In normal web hosting services most of time the server is leased by a customer and hosting provider will get paid by the customer to run the web business. Your colocated server will be provided with high speed Internet connection, bandwidth and an unique IP from data center to run secure web business. Once you follow these simple procedures you can access websites from the provider with the help of given IP. Data center or web hosting company do not have any kind of permission to change or upgrade your colocated hardware.

Before colocating your server just check if data center or colocation service provider is equipped with all the necessary features that helps your server to perform well with the business because  your colocation servers are the only one which helps you to increase the level of your web business.

In order to be in the competition these data centers invest heavily in infrastructure so that they can provide customers with best services. Internet is now an important part of nearly every business on earth. Without internet it is hard to imagine, many business in the world. There is hardly ever a business without a website that means millions of websites daily.

Other than business websites there are millions of other personal sites present on internet. So with internet being used for every business on earth, more and more hosting solutions are coming into light. As the internet usage is growing mostly individual servers are sold because basic hosting cannot handle the weight of the traffic. This one reason is enough to make colocation famous in the world of internet.

Whole infrastructure of a data center is shared between all of its clients and the costs are distributed, in simple words it makes service cheaper for the clients. Colocation includes everything that is needed for a best quality hosting in one place. There are many clients who don’t want to rent a server but instead buy a server, it is not possible to built whole data center only for a server.

Colocation is the solution for all such clients. Another advantages associated with colocation is support, these days all support is provided by the hosting providers. Previously all maintenance have to be done from clients end. Colocation servers which are completely managed by the server providers falls under the category of managed colocation hosting. Those clients who are not technical expert enjoy managed colocation services. These makes colocation more flexible than ever.

Quantity of these kind of companies is growing on an exponential rate. There are many companies sometime called as wholesale data center facility operators. All such data center facilities include all the modern day data center qualities like raised floor space, HVAC cooling, excellent power supply and security. In order to make the colocaion services more flexible these kind of organizations offer customized data center management, construction and designs.

Some of them promote themselves through colocation services. Leasing data center is getting famous because most of the companies want to avoid the capital investment required to build the whole infrastructure. Craze of data center space which boomed in the era of dot com bubble is filled up recently. Now anyone who wants new space has to consider third party operator.

Financial executives mostly fund in those data center investments which reduce operating cost like automation and virtualization. Some other organization which are looking in the future are investing in Cloud Infrastructure. In last 12 months dapce footprint has grown up to 15 million from 13 million square feet.

High Speed Internet  Required -  Cloud Computing’s performance in slow speed internet connections is absurd. Slow connections like dial-up make is Cloud computing  a pain for the user or it can be say it is impossible for the users to enjoy cloud computing on slow connections. Large documents and web-base applications need a lot of bandwidth to download. Is you are using a low speed internet connection then you may feel Cloud Computing will take more than a lifetime to be operational on that type of connection. In simple words Cloud Computing is not for slow connections.

Constant Internet Connection - Cloud Computing without proper internet connection is just like lifeless body. Because you are using internet for accessing both your documents and applications, in case if you don’t have an internet connection you can’t even access your documents. Departed internet connection means no work on the cloud computing and areas where internet connections are slow and are unreliable it can affect your business. Cloud Computing simply stops working without internet connection.

Limited Features - today many web-based applications are not fully featured when compared to their desktop versions. Just for an example there are n-number of things which can be done using Microsoft PowerPoint with the help of Google Presentation’s web based feature. Basics of using Microsoft PowerPoint on Cloud Computing are same but it lacks many of the advanced features of PowerPoint. If you are specially fond of power features, you will not look at cloud computing.

Data Stored is not secure - All the data in Cloud Computing is stored on Cloud. Its your duty to make sure how secure Cloud is? Whether only authorized persons are slowed to access to your confidential data. Concept of cloud computing is new and even if hosting companies say that the data is secured it can’t be a 100% truth. If you will see theoretically data on cloud computing is unsafe as it is replicated along multiple machines. In any case if your data goes missing you don’t have any chance of local or physical backup. Simply depending on cloud can let you down and there is always a risk of failure. In order to save the data only solution is downloading all cloud documents on your machines. However this is a lengthy process and every time your documents upgrades you will have to download a new copy of the application.

Organizations are now asked to check all the operations in a Data Center are working correctly, also all the equipments are secure. Not just the equipments and applications but technologies, people and policies should also be kept under the eye of organization which are required to keep the Data Center active and functioning.

Based on the expert views there are few points or steps which if followed can secure your data center against all the malicious attacks and also make it  more active then ever. Here are the steps:

Set Up a Secure Zone for Network

Once the physical security level is installed the real hard work of securing network  starts. Securing network systems begins with development area followed by test subnet which is separated from the traffic of the development area. Production which is the third area is considered as the most boring area and most of the efforts and time of system administrators is wasted in this area.

Since this zone works on approved production equipments administrators are asked to imply new systems to control production network. Administrators can organize virtual or physical systems to the sub-networks which are attached to the virtual area network. Other than that strict rules related to outgoing and incoming traffic are also deployed.

Before applying rules managers of Data Center should find out the different requirements of the different business which are handled by sub-networks. For example traffic related with production should be restricted to irrelevant websites and other services like e-mail should use ports with outgoing links.

Wireless access points should be avoided in Data Center because even with two factor authentication and wide working radius they are difficult to control. In the security of Data Center there are three steps to be followed, first one is operational framework is ensures global information grid is available which should have integrity and protection. Technical protection is second and third and last is certification and accreditation of applications to be used in data center.

Physical Access should be Secure

Each layer and system in your data center is important, secure access to every room of your Data center. It is seen that commonly data center managers start with other complex tasks like controlling access to systems and mostly forget the physical security measures and concentrate on network side. In a perfect security systems, measures should be taken at every point of the Data Center.

Physical security for a Data Center includes ID cards, fenced campus, bio-metrics system and video surveillance, specially for the outer entrances of the Data Center. Inner Layers doesn’t need all security measures mentioned above and two important security measures should be taken care of are video surveillance and biometrics. One more important type of access to the inner parts of the Data Center is proper locking on the server. This is done to avoid any accidental error which can be caused by any wrong person working on the servers.

Organize Communication among security devices in Data Center

Cloud Computing and Colocation services has changed nearly every style of working in web world, security is also included. Most important thing in cloud computing is securing the data that is flowing between client systems, virtual machines within the data center and also between two data centers. In order to secure everything something more than port protocols is required like application identification technology.

Application identification technology apply signatures which helps in determining which application is peer to peer program or a shareware program. Application denial of service attacks should also be included in your security measures. Traditionally denial of service of attacks was programmed to fight of attack by using the “black hole” technique.

Drawback of this technique was that administrators have to remove all the traffic from the server that is under attack. Nowadays there are other solutions available which helps in determining which traffic is legal and which is illegal.

Offline Processing - there are many users round the world who wish to change data from your database on a machine even when their status is offline i.e. when they are not connected to the network.

Redundancy - with the help of replication you can build a fail-over database server, in case of any failure it can pick up the processing, even on a minute’s notice.

Load balancing - with the help of replication you can divide your data on large number of servers and thus you divide the query load between those servers. Replication therefore helps in enhancing the quality of the server.

Snapshot Replication - it works just like the name indicates. All what publishers have to do is take a snapshot of the entire replicated database and share that with subscribers. Snapshot replication is not used by most of the administrators because of the reason that snapshot replication is resources intensive process. Most commonly snapshot replication is used in those database which rarely undergoes any change. Other use of snapshot replication is to establish replication between systems at the same time as updates are broadcasted with the help of combined replication.

Merge Replication - this type of publisher allows subscribers to make changes independent to the database. Spatiality of these two applications is that they can work without network connection. When connected again the merger replication feature confirm changes made on both sides and make changes in each database. In the case of changes contradict with each other, there is a provision of conflict resolution algorithm which concludes the suitable data. Most common users or merge replication are laptop users, who didn’t get chance to connect to the publishers continuously.

Transactional Replication - best advantage of Transactional replication is it allows database to undergo any change on a regular basis. With transactional replication publishers can monitor changes occurring on the database an then transmitting those changes to the subscribers. This kind of replication can work immediately or on a periodic basis.

Redundant Systems
Systems used in colocation servers hould be redundant and at every point of working they should have proper capacity. Many people get confused with multiple units considering them as redundancy. Ideal configuration for systems used in colocation facilities should be n+1, which means that if there are two units they should run at 50% capacity, and in any case if one fails other will handle the load. Same if there are three units working capacity should be 66%.

Best Connectivity

Major points which decides the Internet Connectivity of a colocation services are as follows:

• Total Bandwidth available for usage
• Accessible Internet backbones
• Uptime guarantee
• Packet loss, jitter and Latency

Carrier-neutral access and Tier -1 carriers, tier-2 carriers all get access to internet using Colocation data centers. Carrier-neutral can be used by any service from any carrier but customers are requested to configure their own routing. Also customers are should maintain their own connections to Internet backbones. Tier-1 is used by Internet giants like AT&T for direct access. Tier-2 is used for routing traffic amongst the multiple Tier-1 providers. In these kind of tiers speed and reliability depends on how effectively traffic is routed. Tier-2 is preferred by most of the clients since routing is configured by the Colocation facility. Also it is more reliable because of the presence of backbones, these backbones network performance and uptime.

Control on Climate

Design of the Colocation Services India itself affects the performance of the systems used in the colocation facility. Air flow between rack rows should be controlled by the server rooms. Hot air generated due to the heat produced by the servers should be blown in one direction and cool air to keep the servers cool should exit from another direction. Only dedicated hot and cols air flow can save the servers from overheating and finally burning down. Cold sir and humidity is controlled by correctly sized and redundant climate control units. As we all know climate requirements for the server are strict and they only work properly when they are installed under suitable working environment. Servers need 50% humidity and 70 degrees of temperature. Both CRAC units and chillers for the server rooms should be included in a Colocation facility. Cooling capacity is calculated by total tonnage by the square footage.

Power Required

Power to the colocation is like oxygen to the humans, if it fails to perform then you are in deep trouble. UPS and generators should be used for backup and they are necessary to keep the network online. UPS are used when power is shifted from regular to the generators. Generators should be there 24X7 for immediate backup power. Power system of a colocation facility should be properly working and should have following features for perfection:

• Redundant and multiple UPS because of the reason UPS fails very oftenly.
• Generator which can handle at least 1.5 time the total building load

Equal Distribution of Traffic

Both hardware and logic of distribution has an important effect on connectivity. The way traffic is divided plays an important role in the performance of routing. If your distribution covers three below given points than it is perfect:

• In order to continually adjusting routes to find the most effective one Performance based distribution is should be used. Performance based concentrates on performance rather then price.

• Switches and routers should be redundant and be working on full working for the customers.

• Distributions should be done between more than 4-5 clients.

• Improve physical space in Data center and also reduce server sprawl.
• Hardware maintenance cost is reduced since number of physical servers are  also reduced.
• Speed up the network thus making provision for new services.
• Performance and resource utilization is improved.
• Applications are quickly developed and organized and downtime is avoided due to maintenance windows.
• Flawlessly mange and scale the infrastructure based on various industrial demands.

There are many software which helps in organizing server virtualization. Some of the most famous and most conveniently applied virtualization servers are:

Windows Virtual Server

Windows virtual server is loved by those who only want to have Microsoft type of environment, using Windows XP or Windows Server 2003 operating systems. There are two versions provided by Microsoft for its Windows Virtual Server 2005 Standard and Enterprise Edition. Enterprise Edition supports can host a server with as much as 32 processors. Standard on the other hand support server with only 4 processors. The enterprise edition can be downloaded free of charge.

XenSource

It is launched almost three years ago. XenSource is based on a open source project sponsored by Linux and known as Xen. It is a good option for those who like open source products then proprietary ones. XenSource proved itself in cost effectiveness but it still has to prove itself in quality service.

VMWare

It is the leading software of the virtualization process. Launched in 1998 it was VMWare which bought virtualization to the mainstream through  X86 computing platform. There are option for everyone from small to big business and at the wide range of price points. Features of VMWare are never ending and it benefit’s the host for every server environment.
