Why managed Dedicated Server Hosting is helpful For Companies.

January 24th, 2011

If you have decided to get hold of dedicated server on lease from a reputed firm that renders web based solutions,your next duty is managing it. This engage a variety of tasks, which contain administering the server, dealing with the OS and any concern that come up related to the same. All of it is very technical and time consuming, but web hosting firms take care of it by providing high quality server management services. Availing fully managed dedicated servers is very cost effective and provides you the time to focus on running an organization rather than worrying about technicalities of servers.

Since firms that lease dedicated servers to organizations hold expertise in all technical aspects of the servers, they carry out the administrative activities on your behalf,while you rest back. The fee levied by the hosting firm is quite nominal, it is quite cost effective and helps in more ways than one. Such web hosting firms examine the hardware as well as the software of the server in a skillful manner, something a beginner can never achieve This way, the server delivers better performance than it would in case of unmanaged service.

Due to the expertise of the hosting firms in executing the administration of dedicated server they become more stable and reliable and operate exceptionally well over long durations without any glitches. These also attain the feature of greater security due to the familiarity of the specialists with the servers and their details. Furthermore, if you are not satisfied with the dedicated servers management by such firms due to some customary problem, they provide 24×7 support as part of their hosting package.

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.

Changing Dedicated IP to Exim Mail Engine Formats for /etc/mailhelo, mailips, etc.

January 17th, 2011

I have to change how mail is sent from one of our machines because it is on a network with a poor reputation. I have additional ips and can switch the sending ip to something else.

When I look at the options in EXIM CONFIGURATION I see:

** send HELO based on the domain name in /etc/mailhelo (*: HELONAME can be added to the file to change the default helo name) [?]
Send HELO based on the domain name in /etc/mailhelo (*: HELONAME can be added to the file to change the default helo name)

** Send outgoing mail from the ip that matches the domain name in /etc/mailips (*: IP can be added to the file to change the main outgoing interface) [?]
Send outgoing mail from the ip that matches the domain name in /etc/mailips (*: IP can be added to the file to change the main outgoing interface)

** Automaticlly send outgoing mail from the account’s IP address instead of the main IP address. Warning: If you turn this setting on you should make sure reverse DNS entries match the ones in /etc/mail_reverse_dns. [?]
Automaticlly send outgoing mail from the account’s IP address instead of the main IP address.

How do I change the info for these files, all of them are currently empty except for /etc/mail_reverse_dns which has the main server ip and machine name. Do I just edit it manually with VI or PICO and it will work or will it be blown away with the next “upcp”?

What is the format for these three files?

You may use any command-line text editor such as vi (or vim), nano (or pico), to edit the files. As long as the automatic option is not in use you can manually update and manage the mailhelo and mailips files without them being overwritten.

The easiest method to see a full version of the files with proper syntax is to temporarily enable the following “automatic” option:
WHM: Main >> Service Configuration >> Exim Configuration Editor >> Standard Options >> Domains and IPs
* Automatically send outgoing mail from the account’s IP address instead of the main IP address. Warning: If you turn this setting on you should make sure reverse DNS entries match the ones in /etc/mail_reverse_dns

the above option will create the files so you can simply view their contents to see how they are used.

Alternatively, you can manually create them based off the following examples, while being sure to use your own domains and IP addresses where applicable; however, please note that to retain customizations of the two files, mailhelo and mailips, it is necessary to enable the relevant options via the Exim Configuration Editor in WHM as seen below.

WHM: Main >> Service Configuration >> Exim Configuration Editor >> Standard Options >> Domains and IPs
* Send HELO based on the domain name in /etc/mailhelo (*: HELONAME can be added to the file to change the default helo name)
* Send outgoing mail from the ip that matches the domain name in /etc/mailips (*: IP can be added to the file to change the main outgoing interface)

Full Path: “/etc/mailhelo”

Code:

domain2.tld: domain2.tld

sub.domain2.tld: domain2.tld

addondomain.tld: domain2.tld

other.domain3.tld: other.domain3.tld

*: server1.domain1.tld

In mailhelo, the example entry that begins with an asterisk sets the default HELO for domains without their own specific entry; you could, if desired, just have the default set and nothing else.

The “#.#.#.#” entries in the following two examples are meant to represent IP addresses on your system; be sure to use only valid, public IP addresses that are accessible via the Internet.

Full Path: “/etc/mailips”

Code:

domain2.tld: #.#.#.2

sub.domain2.tld: #.#.#.2

addondomain.tld: #.#.#.2

other.domain3.tld: #.#.#.3

*: #.#.#.1

In mailips, the example entry that begins with an asterisk sets the default outbound (sending) IP address for domains without their own specific entry; you could, if desired, just have the default set and nothing else.

You should not have to manually edit or manage the mail_reverse_dns file; the only two that you would manually edit are mailhelo and mailips. For the sake of showing an example, though, here is what the mail_reverse_dns file might look like:

Full Path: “/etc/mail_reverse_dns”

Code:

#.#.#.1: server1.domain1.tld

#.#.#.2: domain2.tld

#.#.#.3: other.domain3.tld

To help understand why the above examples look the way they do, in terms of why a particular domain has a specific HELO value and or why a particular domain has a specific outbound IP, and to help show what you might expect to see from the aforementioned “automatic” option, the following could be assumed:
1.) “domain2.tld” is a primary domain
2.) “sub.domain2.tld” is a sub-domain of “domain2.tld”
3.) “addondomain.tld” is an add-on domain of “domain2.tld”
4.) “other.domain3.tld” is an also primary domain
5.) “server1.domain1.tld” is the server hostname

If you opt to manually create, update and manage the mailhelo and mailips files, you are free to customize them as needed provided they contain the correct syntax and use only valid domains and IP addresses.

Resellers: thoughts toward sell more web hosting.

January 12th, 2011

1. Clearly define your audience:
this is one of those bits of advice that’s sounds blindingly obvious, but so few people actually do. We’ve seen big companies that couldn’t tell you who their core target audience is, or you’d get a different answer depending on who you spoke to. Ask yourself these questions…
• Who is our ideal customer?
• What do they want?
• Why should they choose me?
• Where do they go?
• How do I let them know I exist?

Life is so much easier once you have a clearly defined target market. You know what type of product to create, how much to charge for it, how to position your brand and where to advertise your services. Make the product fit the customer, not the customer fit the product.

2. Be creative with your marketing budget:
You can’t compete with the large web hosting company’s marketing budgets; it’s a simple as that. They spend £1m+ per year and if you try to go toe to toe with them, you’ll probably go bust. I’ve seen it happen a couple of times over the years I’ve been working in the industry. For example, the most competitive keywords advertising on Google are off limits to all but the biggest spenders with the average cost per click for “web hosting” currently running at £8. Some ideas you could pursue include:

• A lot of web hosts haven’t really got their head around social media. They have twitter accounts and pages on Facebook, but I’d argue 85% of them are poorly thought out or token efforts. That’s a gap for you to fill.

• Online press releases are great ways to announce news to a large audience, establish authority and build quality incoming links. At only £100 per release through a distribution service, this is great value for money.

• I personally would not go near the most competitive keywords through Google AdWords if I was on a limited budget but I would still use the Google Display Network. Put together a tight list of target sites and advertise your service there using graphical banners.

3. Assemble your customers:
Excellent customer support and product performance will lead to customers spreading the word without much encouragement. However, you can be more proactive than that and get even more customers to refer you to other people who are looking for web hosting. A refer a friend program with a financial incentive is a tried and tested way of getting customers to refer people. This can be in the shape of cash, credit or vouchers. Review sites are a big part of a customer’s journey. Unfortunately the reviews being left on these sites tend to be from customers who have had a bad experience, certainly much more than those who are happy. Companies are becoming wise to this and starting to counter the negativity by asking their customers to review them, and there is no reason why you can’t do the same.

4. Get to the know the web hosting industry:
You are not competing in a vacuum and the more you know about the industry you are operating in, the more successful you will be. Who are your competitors, where do people go to research web hosts and who are the major web hosting news outlets with the most authority? If you can answer all those questions, you can relax. If not, here are some links to get you started…

5. Sell the core products:
Shared hosting, domain names, dedicated servers email solutions are the bedrock of non-managed web hosting companies. They also offer huge cross sell and up sell opportunities. For example:
• Domains: More domains, email, shared web hosting, domain privacy
• Shared web hosting: Dedicated servers, Hosted Exchange, search engine submission, SSL certificates, higher spec hosting
• Dedicated servers: Server back up, higher spec servers, cpanel, MS SQL, Hosted Exchange, SS certificates

6. Get visitors to trust you:
If you are asking a customer to essentially look after their web site and make sure it is secure and always accessible, there has to be an element of trust on the part of the customer. The challenge is to make them trust you enough to hand over their money. You can reduce the level of perceived risk through an attractive and modern website. Nothing screams “Stay away” more than a website that looks like it escaped from the 90’s.

Beyond being sexy to look at, all but the most carefree of people like to know they are part of a group, it makes them feel more comfortable. Positive customer reviews and testimonials go a long way to relaxing potential customers. If you can source them, case studies are a great way of showing visitors their peers are already your customers.

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

Web Hosting Services to Publish a Blog or Website.

December 13th, 2010

In order to publish a blog or website online and make it accessible to computers connected to the Internet you need a Web host. A Web Host is also sometimes referred to as a Web Server and it is just like another computer somewhere else in the online world that provides a convenient and safe space to store your blog and website pages and files so that people can access to them 24/7/365 via the World Wide Web.

You can also link your domain name to your web host so as to allow online users to access your website pages and files via your domain name. When you first link your domain name to your web host it is assigned with a unique IP that points to your data stored on the server. And whenever people who wanted to access your web-pages and files from any place on the internet enters your domain name into their browser’s address bar, what happens is the IP-address associated with it is located and website is loaded from your web host.

Instead of using a web server as a central place on the internet to get access to your website pages and files you can also host yourself using your own personal server at the comfort of your home but it is not a preferred choice for many because of the fact that it is very complicated to setup, maintain and also to ensure that your server is running 24×7. So, it is much more affordable, reliable, simpler and hassle free to use a web hosting service instead of doing it yourself.

There are different types of hosting depending on the services provided by the web hosting companies.

Here are some of the most common ones: Free Web Hosting,Shared Web Hosting,Reseller Web Hosting,Dedicated Hosting,Virtual Dedicated Server (VDS) Hosting,Colocation Web Hosting,Cloud Hosting,Clustered Hosting,Grid Hosting etc.
