Reseller Hosting Can be a New line of business Choice for Web Designers

January 18th, 2011

When we talk about the web hosting industry, we generally can think of two classes- the provider and the client side. One offer the service, while the other utilizes it to run his or her business online. But actually, there is a third side to it too or one can say a service model that lies between these two sides i.e. reseller hosting. This is a competent yet easy-to handle business model that can anytime be blended with any other business model, enabling owner to earn doubled profits.

The option of Reseller hosting services has been opening opportunities for a number of small business owners who are aiming at taking their current revenue stream higher by rendering custom hosting packages to their client base. However, amongst all business models, the one that seems most apt to be united and rendered with reseller hosting package is of web development services. This is why web developers having a consistently growing client base must consider adding web hosting service model to their line of business.

Including the Cost of Services

an ideal way to begin with this is starting to sell all-inclusive packages. Such packages take care of complete site development and management on the basis of a set monthly fee. Typically, this monthly fee includes expenses of hosting, site maintenance and custom design tweaks that are made as per clients’ suggestions. By combining the two services together, you can actually quote a higher price and aim to make a bigger profit. With the added advantage of being a web designer, you may easily convince your client with a convenient package comprising site design, organization and hosting.

Internet Businessmen

pitching for already established online websites or big giants is not very suitable for you since these will already have big hosting plans. Hitting the right set of crowd is very important for business growth at any stage. Hence, rather than opting for experienced online businessmen, it is better to go after offline crowd, since their information and experience in this field would be much limited. Offline business owners who are not technically inclined are more likely to buy reseller plans, and let me tell you this does not limit your targeted crowd.

One thing that is always consistent with every business owner is the aspiration of growing bigger. Be it a medical shop or a giant corporate house, every business wishes to expand more and more, so that they reach to the biggest of podium of clients and customers. Fortunately, World Wide Web successfully fulfills this aspiration of reaching out the masses, economically. Hence for a reseller hosting service provider, the clientele is humongous. Moreover, since you are a web developer who is ready to take up the projects of web hosting services, the combination of offering website development and hosting may pitch your sales much higher.

Cloud Hosting: The Good, The Bad, and The Ugly

January 18th, 2011

In recent years, there has been a blurring of distinction between the terms virtualization and cloud computing.  Virtualization is actually not new; it was invented by IBM nearly 40 years ago and allows an IT department to split a single server into several virtual dedicated servers or “virtual machines (VM)”.

This abstraction of hardware and software offer a number of benefits including simplicity, reduced costs, portability and increased agility for a web host or an IT department.

Cloud computing on the other hand extends virtualization through the Internet “As a Service” to deliver remote “on-demand” resources to an IT department at a fraction of traditional hosting costs.

Theoretically, nothing is exempt from end-to-end IT virtualisation including hardware, platforms or software, all of which may be accessed remotely from a hosting provider (via the Internet) as part of a public or private cloud based service

The implications of cloud computing are profound and far-reaching and could be distilled into this simple formula:  Cloud computing = Virtualizations + Internet.

While virtualization has been around for a while, it’s only recently that the managerial and technical capabilities to execute public and private clouds have come together in such a way as to realize the promise of this technology for businesses and enterprise customers over the Internet.

Increasingly, web-hosting platforms in the UK and around the world are introducing new cloud services at a frenetic pace. But, some are struggling more than others to offer adequate support services and keep pace with the evolving demands of their customers based on both private and public virtual dedicated servers.

Further, while forward-thinking companies are waking up to the benefits of the cloud they are still not completely comfortable off shoring their data, applications and storage requirements to a public cloud service provider.

The eternal specter of security looms over any cloud service and is being pushed along by a media hungry to expose the good and bad in this exciting re-born technology.

It’s worthwhile summarizing both the pros and cons of cloud hosting and where you as a decision-maker should be positioning your company.

The Good

Without doubt one of the key benefits to deploying a public cloud is how quick and painless it is. The quick, easy wizard-driven process surprises many skeptics and turns non-believers into converts.

If you add in the elastic ability to scale to meet seasonable demands over Xmas and New Year, then things are looking pretty good.

But it gets even better. Statistics show that some companies may save in costs between 50-70% over traditional colocated and dedicated servers provided they follow a gradual deployment timeline, rather than an overly ambitious one.

Plus, because you can isolate virtual machines (VM) from each other you can minimize exposure to risk between different applications running on different OS platforms.  Many companies are also loving the portability feature of cloud VM’s which allows them to migrate from one server to the next in record time.

The list goes on, including the benefits of standardizing your IT technology platform and reducing complexity. The ability to self-service your future requirements quickly and effortlessly via a metered pay-as-you-go business model appeals to many decision-makers.

Finally, if you find yourself nodding vigorously while watching Al Gore’s “An Inconvenient Truth” then you will rejoice in the fact that a public or private cloud promises to lower your carbon footprint and promote “Green IT” as a real concept within your organization.

The Bad

Of course, the biggest fear associated with implementing a public cloud service or a private virtualized server usually centers on security.  Many enterprise customers are skeptical that web hosts can actually protect their resources in the cloud.

The recent phishing attack on Google by Chinese government-backed hackers and the subsequent Denial of Service (DoS) attack on the infamous WikiLeaks website housed on Amazon cloud servers have temporarily raised doubt in some people’s minds.

Ironically, these two incidents will actually serve to accelerate increased security in the cloud and eliminate future concerns. The best minds in the business are currently engaged in this venture. Further, customers may also consider opting for a private cloud over a public virtualized server if they wish to absolutely control the level of compliance and security; they do not need to wait for a web host to catch up with their expectations.  Expect to see private clouds grow in popularity over the next few years.

The Ugly

Yes, it can get ugly. While virtual dedicated servers are generally safe, easy to administer and cost affective, they can be implemented badly, even terribly.  The old expression “garbage in, garbage out” applies just as strongly to implementation as it does to CRM data entry.  When companies rush into a cloud deployment they risk inconsistent results, security implications and costly delays in bringing a product to market.  Instead, it’s recommended that a company start small and gradually add new cloud features “on-demand” as required. This approach, for example, may take advantage of a Xen cloud server to safely test new products in a sandbox environment before making products live to a customer.

The way forward

All the points highlighted above must be tempered by the fact that your ultimate success will depend on the knowledge, experience and customer support features of the web host you select to drive your new cloud implementations.

A number of web hosts in the UK are suffering from growing pains — growing too quickly, too fast, which increases risk for a company seeking long-term stability in the cloud.

Further, make sure your web host demonstrates the ability to offer flexible, customized SLAs to help tailor your requirements in a scalable, cost-effective and safe manner.

If you follow these rules things will be mostly good, hardly ever bad and certainly never ugly.

Strengthen Your Web Servers with Load Balancing

January 5th, 2011

On the Internet, organizations whose has web sites and also get huge traffic usually use load balancing technique to manage server. Every webmaster keeps a complete eye on there load balance to mange the web server traffic. The web servers are one of the most important factors for growing business. As sever administrator manage the load balance in different ways. The load balancing of the web server technique is been done in round-robin fashion.

For balancing the website traffic, there are several approaches. The webs servers are are one approach is to route each request in turn to a different server host address in a domain name system (DNS) table. Balancing the web server load is a procedure in which inbound internet protocol (IP) traffic can be distributed across multiple load balancing server or on the Load balancing Switch. There is multiple load balancing solution available with in the web hosting industry. There are high end Internet load balancing solution as well as load balance routers to manage online server.

In this type of balancing technique two online web servers are being used to balance the complete work load on the servers and the third server is used to determine which server to assign the work to. Since load balancing requires multiple servers, it is usually combined with fail over and backup services. In some approaches, the web server is distributed over different geographic locations. Load balancing can be implemented with hardware, software, or a combination of both. Typically, load balancing is the main reason for computer server clustering.

A Network load balancing is also a balancing technique to distribute workload equally across two or more web server, CPUs, hard drives, network links, or other resources. Which indeed to get optimal resource utilization, maximize throughput, minimize response time, and avoid overload. Load balancing is dividing the amount of work that a computer has to do between two or more computers so that more work gets done in the same amount of time and, in general, all users get served faster. Commonly the network load balancing can also manage popular web sites that usually get high traffic.

Load balancing enhances the performance of the web server, leads to their optimal utilization and ensures that no single server is overwhelmed. Network load balancing also helps in managing DNS servers. The large Internet Relay Chat networks, high-bandwidth File Transfer Protocol sites are also being monitor. Using multiple components with load balancing, instead of a single component, may increase scalability and reliability with redundancy. The load balancing of a service is provided by a dedicated program or hardware device (such as a multilayer switch or a DNS server). Load balancing is a procedure in which inbound internet protocol (IP) traffic can be distributed across multiple servers.

Benefits of Load Balancing:-

  • Improves server performance – With the help of load balancing server the performance is achieved .The advanced load balancing technique can easily re-direct end-user service requests to the servers with the fastest response times.
  • Adds Intelligence – The servers also has a feature in which it allow you to send requests for certain web pages to specific groups of servers. The special request is been done with the help of priority to the servers.
  • Enhanced availability -If the online server application gets failed the load balancing can be easily redistributed by the end-user service requests to different webservers within a server farm or to servers in another location to manage the server load balancing.
  • Creates Resilience – High- Availability pairs for load balancer resilience, and creates fault-tolerance for your back-end servers.
  • Improves Reliability – With the help of online monitoring on the health of your web servers. The failed servers easily get detected and removed from the cluster until they recover.
  • Improved flexibility and scalability – Majority of the content intensive applications has been scaled beyond the point of limits where as a single server can provide the web based client a adequate processing power.
  • One-Click Session Persistence – A client is just one click away, for the sticky sessions for your web application when ever required by the.

Transferring Your Data to the Cloud.

December 28th, 2010

Cloud computing has not yet taken over the server industry, and there are plenty who are resisting all attempts. Nevertheless, the usage of cloud services and hybrid cloud deployments has increased gradually, and anyone who uses dedicated servers and has some type of web presence should at least take a look at it.

One of the many concerns system administrators, security experts, and free software advocates have about cloud servers or software as a service (SaaS) is that the moment they move their data to the cloud, it is out of their hands and under the control of a third party. This is a valid concern.

Once another company controls the access to and delivery of your data, you are at the whims of their shareholders. The moment they decide to pull the plug on a project or (even worse) have their plug pulled by bankruptcy, government seizure, or any other unfortunate event, you may be left with nothing.

For cloud technologies that use free and open source software, it may be rudimentary to export data. For cloud services that use proprietary data formats and closed source software, you may have no way to convert data to a useable format when moving from one to another. For that reason, it is important to investigate the company’s policies and software user agreement ahead of time, before you possibly put yourself and your business in a compromising position.

Thousands of websites and millions of pieces of private data are increasingly in one big cloud, where some of the old rules of data security are out the window.

What’s at risk?

Take the example of credit card data. Most of us don’t think twice about saving account numbers and security codes into our online shopping profiles. The Payment Card Industry (or PCI) is a global information security standard established by a consortium including Visa Card, MasterCard, American Express and Discover, that places specific requirements on the operational infrastructure that handles high-risk data like credit card information. If an infrastructure doesn’t conform to any and all PCI regulations, then it’s not PCI compliant. And because cloud infrastructure is so vastly different than that what PCI was written for, most cloud service providers are in fact, not PCI compliant.

How a cloud service provider encrypts client data is also key to security. According to Forrester cloud analyst Chenxi Wang, cloud data encryption can be scattershot. Some services encrypt their data; some don’t. For those that encrypt, it’s worth figuring out whether the encryption is strong enough, whether the physical server that stores your data is entirely encrypted (ie. is all client data encrypted the same way?) or whether the service provider offers applications that encrypt your data separately and with different keys than other stored data.

That last concern stems from a popular cloud practice: some cloud providers store data from multiple clients on the same physical server. So, Client A may be running one “virtual machine” and Client B can be running on another “virtual machine,” but both could be physically running on the same server. If an experienced hacker gains access to Client A via a security hole, it’s not outside of the realm of possibility for the hacker to gain access to Client B’s data as well. Even Client A, if they’re up to no good, could become the culprit.

“The risk of that, depending on how the cloud provider, may be minimal, or it may be quite substantial.” admits Wang. “From the absolute security stance, there is a risk that the other company who happens to rely on the same infrastructure may be able to utilize some covert terminal, or some kind of interface that’s available to actually hack into your part of the infrastructure.”

Another concern is the use of the third-party companies for various components of a cloud service. Cloud services are relying on third parties more and more.

We know recent example where third party usage has gone horribly awry. For back-up purposes, client data is often written to tapes or drives, but after a given period of time, most back-ups need to be destroyed. Recently, an unnamed cloud provider sent their back-up tapes to a data disposal company. The data disposal company lost all the tapes, and thus all the cloud client data on them.

“The cloud provider was put in a very bad situation because they don’t have any assurance the data was actually destroyed.”

How Many IP Addresses Do I Need?

December 28th, 2010

As you may have heard, there are a finite number of IP addresses available to Internet Service Providers (ISP). Once they are all used up, the only way to get more is to reassign them. In technical terms, the limited number of IP addresses refers to the IPv4 address space, while there is plenty of room in the IPv6 address space.

Until ISPs begin fully adopting IPv6 technology, however, IP addresses will be sold at a premium. The question is: how many do you really need for your dedicated server? The answer really depends on where and how your server is hosted, the number and type of websites you are running, and how you use your server.

For a server with a single enterprise website and one central focus, a single dedicated IP may be all you need. This, however, assumes you also have nameserver IPs on another machine or from a service. If your server is housed in a remote datacenter, your nameservers may be managed by the provider. If not, you will need at least two IP addresses.

If you have more than one website, you can usually use shared IPs for most of them, unless they require SSL for ecommerce or community logins. For encrypted sites, you will need an IP for each one, if you want authenticated SSL certificates.

If you are using your server for web hosting, you may need to regularly acquire IP addresses for your customers, and you should use a service that will allow you to quickly and easily add more. Often times, you can purchase them in bulk, depending on the number you need.

It is a good idea to know ahead of time how many IP addresses you think you might want, but even if you repurpose your server at a later date, you should still be able to add more IPs without any difficulty.

I’ve seen a lot of reasons given by ESPs for why they need so many IP addresses:

  1. I need at least one IP address per customer, to handle IP based reputation
  2. I need many IP addresses so my MTAs can handle the volume of mail sent
  3. I need many IP addresses so that I can work around ISP throttling limits
  4. I need multiple IP addresses per customer so that that customer can deliver mail in a timely manner
  5. I need multiple IP addresses per customer so as to manage filtering issues
  6. I need multiple IP addresses in different locations to provide redundancy against network outages
  7. I need multiple IP addresses in different locations so as to provide redundancy against blacklisting of my ISP

Public Clouds vs. Private Clouds.

December 13th, 2010

“The Cloud” is the latest tech buzzword, and although the term has been around for quite a while, it is starting to gain attention among the general public, particularly due to some oft-aired commercials by Microsoft. The business world is not immune to the hype, and some terminology you might have come across when making technology decisions are “public clouds” and “private clouds”.

The idea of a public cloud is the basic concept you already know, if you are at all familiar with cloud computing. Services, applications, or even entire operating systems are hosted and managed remotely by a third party, providing you, the customer, with access. Examples include Google Apps and Microsoft Office 365, both of which provide software as a service (SaaS).

The term “private cloud” refers to all of the above, minus the third party. Essentially, you are hosting your own “cloud”. If you are sitting at home thinking this is a complete contradiction, you’re right. While the idea behind the term is probably genuine, as it intends to replicate software and platforms served over the cloud in a closed on-premise environment, the term has no real technical value for people in IT departments. These are just dedicated servers wearing different clothes.

While one could argue that the main difference between a “private cloud” and regularly used business software is that the “private cloud” software is not installed on local computers, but this concept of using web-based applications in an intranet is nothing new and predates the term “cloud computing” all together. The important lesson to be learned when shopping for dedicated servers or web-based services is to read between the lines and not get caught up in empty terminology.

The Value of SPF Records.

December 13th, 2010

SPF stands for Sender Policy Framework and it is the standard established in RFC 4408. Essentially, SPF validates emails sent to a mail server to determine if a message is spam. One of the biggest problems faced by ISPs trying to fight spam is the spoofing of IP addresses and domains. In such cases, blacklisting an IP address has little effect, since the spammer can use false ones. SPF is a system for validating emails before they are delivered.

SPF works by not allowing senders to forge FROM addresses. When a server establishes its mail server, it will broadcast that it only sends mail from certain systems. If a machine not on the list sends a message from the domain, the SPF-enabled server will reject it.

The benefit of SPF is that ISPs and hosting providers can set standards for mail delivery, denying message senders that do not provide valid SPF records. The unfortunate reality, however, is that the standard requires ISP adoption, and without it, SPF records are rather useless. If, for example, one ISP enforces the standard but another does not, spam can still be sent from one to the other.

It is not terribly difficult to setup SPF records on your dedicated server. Once setup, it does not require any further action on your part, and you will be contributing to create a more clutter-free Internet.

Monitoring Your VPS or Dedicated Server.

December 6th, 2010

One of the most important factors that you should be constantly monitoring with your VPS or dedicated server, especially if you host clients on it, is the uptime of it; this means that you should always be using some type of monitoring service to ensure that your VPS or dedicated server, and if it isn’t you need to ensure that you are notified of the down time ASAP so that you are able to sort the problem out yourself, or notify the support team of your web host to ensure that the down time caused is minimal and that your server will come back online ASAP.

If you are a web host which is providing a responsible and sensible service, then in your terms and conditions you will probably have conditions set out regarding up uptime, which in most cases states things such as if a customer’s service is down for over a certain amount of time, or if the monthly uptime record doesn’t meet the one which is guaranteed then customers are able to request a refund; this in itself should provide you with the motivation to fix a server problem if you have set such rules out in your terms and conditions, since most companies wouldn’t want a servers worth of customers requesting refunds since they don’t think they have been provided with the amount of uptime which has been guaranteed. Most web hosts use their own internal monitoring system for their servers, since in most cases it will alert them quicker to a problem than an external solution would since an internal system is most likely monitored more closely, but with an external solution in place as backup in case the internal one fails. One thing to consider is that most external monitoring services monitor your website or server from multiple geographically different locations which means that they are able to provide a more reliable source of information when it comes to checking to see whether your VPS or dedicated server is online or not when compared to a monitoring system which is monitoring your VPS or dedicated server from one location or from one country or data center, which means that the produced results might not always be accurate and reliable.

When considering uptime solutions for your VPS or dedicated server, you should always take into consideration the effect that a program might have on the performance of your VPS or dedicated server; for example if you use an internal solution then you might need to install an ‘agent’ program which posts data about your server back to the master monitoring node, since information such as the speed that your server’s CPU is running at and the amount of memory that your server has left are factors that can only be gained by internal access to your server unlike other factors such as whether certain services are running or not that can be found out easily via pinging the port which the service runs on. You want to try and maximize the uptime of your VPS or dedicated server, which means that you should optimize the programs that you have installed on it, so that they don’t use up too many resources since the most common reason for a server crashing is that there aren’t enough resources available to keep the operating system going, which means that it just crashes because it is unable to run for any longer on the scarce resources that are available for it.

Conclusion

In conclusion, with the use of either internal or external monitoring systems, you are able to maximize the uptime of your VPS Hosting or dedicated server, thus ensuring that your customers, if you host them on your server, are happy with the service and level of uptime that you have been able to provide them with; you are also ensuring if you use your server for other purposes such as for receiving emails or for a website that emails are received as often as possible, and that visitors will still return to your website thus increasing your amount of revenue that you earn from adverts if applicable. You can also optimize your VPS or dedicated server as well as the programs that it runs to ensure that the amount of resources used is far lower, thus ensuring that you can install some more applications on your VPS or dedicated server or leave it as it is so that it is able to run fast; if running cPanel, then you can use the new optimized version since this will run much fast on a lower specification machine since it has been designed to take up less memory and utilize less CPU.

If you choose to use an internal monitoring system then you gain the ability to monitor internal factors of your server, such as the amount of CPU and memory that is available for use by the operating system and programs that you have installed on your VPS or dedicated server – this is very important if you are running a server which is hosting web hosting and design clients, since you don’t want their websites going down because of a lack of resources. Other factors which you might want to consider when choosing a monitoring system is the accuracy of the results that are collected and in turn produced; for example, with an external monitoring system you will want to be considering how spread the multiple geographical monitoring stations are and with the case of an internal monitoring system, you should find out whether internal server resources can be monitored or not – this will give you an advantage since you will be able to monitor all aspects of your server then, both internal and external which means that accurate results should be produced.

Benefits of dedicated servers in games website.

November 24th, 2010

Every once life one is the time when he/she have his own game to play. In today’s market you can see allover digital games are more popular like xbox360, play station and Nintendo games capture the game markets. But can you think it why everyone likes to play online? And this base idea of dedicated server games theme.

Everyone cannot afford to buy Xbox 360, play-station or Nintendo But; current games versions available on Internet are better than to play alone. There quality display, speed is specially made to give you a high quality excitement, and these kinds of things are possible through dedicated servers.

There quality, display, speed are in particular made to give you a far above the ground quality thrill, and these kinds of things are probable through dedicated servers. If you pay money for a game DVD, how much time you play? At one period, to play that game getting so boring, this is the major reason behind popularity of online games. With lend a hand of dedicated game servers’ people can play against someone else there is no want of same play station. This is the main reason, the online game providers never end require of dedicated game servers. Network bandwidth is one the crucial part in gaming business, because it must be compulsory always in upstream. Here home or office broadband Internet connection is not plenty. Normally with this type of connection, player does not get upstream bandwidth to host out-and-out game servers more than five to ten clients, but in the past years this is the only option was available for game hosting.

Couple of years before, the player who have the game, host the server and also run the client. However, on another side, the bandwidth provider of latest broadband service, handle the outgoing traffic at same time, therefore the host computer struggled to provide a good quality of service to the players on the network, while at the same time running the game on the same computer.

However, the online game providers realized, the importance of dedicated servers, because they need professional server to read data and transferring huge amounts of data as fast as players need it, therefore they purchased rack mounted server machines and collocated them inside Data Center Services to host their games Website. They paid monthly charges for it and the services they got is invaluable, these set ups improved the quality of their games.

Why use a Linux Dedicated Server?

November 3rd, 2010

As you may already know, linux is the most widely used operating system on the market. The basic concept behind linux when it was created in 1991 is to offer great software absolutely free and open source. Linux was created under the GNU GPL license which is open source and therefore people can use its code and change it for their own needs. Since then, linux has gained a lot of popularity and today it is used of many linux dedicated servers.

The most popular factor when a business is considering a dedicated server is cost. Most linux operating systems are completely free, which enables gogax to offer cheap dedicated servers. As opposed to a Windows Dedicated Server which requires licensing fees for the operating system, people will tend to prefer linux for that matter.
Another factor is how reliable and secure the linux operating system has grown to become. We have seen some linux servers running for over 4 years without a single reboot needed. If we compare that to windows servers, they often need reboots after os updates, software installation and other tasks performed on the server. For a personal user this is no big deal, but if online presence is crucial to your business or online store, a reboot can mean loss of business. Many people will argue whether linux or windows is more secure and stable. With time, we personally have found that linux is more stable and can run as a web server for years without any intervention. Unfortunately, it is not the case for Windows servers today.
Linux has some great functions on dedicated servers. It does http web server (apache), php programming language, mysql database and many other features. Those are included in a default setup of the linux operating system. All these elements together offer very stable and secure performance. The best part of it all, many developers have made great free software that runs on linux operating systems. Those are all freely available on a linux dedicated server.
Security: One of the main reasons that people like Linux is that it’s more secure than Windows. The main reason for this is that Linux hasn’t been around as long, and there aren’t as many viruses built to get into it yet. This means that your website information can be somewhat safer on a Linux host.
Cost: Because it’s open source software, Linux hosting solutions are cheaper than Windows hosting options. Although most shared server options are really affordable right now, Linux often presents even more affordable options.
Scaling: If you’re going to start your website small and work it up to a larger site without changing servers, Linux hosting is definitely a good option. This type of service has very efficient scalability, and it’s really easy to keep your website going on the same platform without making any major changes.
Options: Because Linux is one of the most popular hosting options on the Internet, there are literally tons of options with it. You can find hundreds of hosting companies, many of which offer excellent services and extras to their packages.
So why not use a linux dedicated server.
