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.

Cloud Computing provides a strong frame to a company to solve one of the most serious problem for IT industry that is Resource Planning. Every new company dreams of getting famous in few days and expect that new clients start using their services. . But for the IT department this can be nightmare because such flow of traffic will require more and more computing power than on any other day. Now to handle the situation if the company buys many computer equipments, than on an average day most of the machines will sit idle. From other point of view if the systems of a company are too weak to handle the load then they might crash leaving many clients and business in bizarre. This is where cloud computing comes into action. Cloud Computing allows a company to use as much as resources as they want and handle the sudden increase of traffic. And on the day when traffic is low company can save money by only using few machines and thus saving a lot of money. Computer equipments are not so costly how they used to be in past times, but the administration of machines is expensive. To solve this problem what Cloud Computing do is basically gathering large number of low cost computers, all other requirements like maintenance procedures and management of systems can all be automated. Therefore by using Cloud Computing you need very few administrators which can manage thousands of machine. Third and th most important advantage of Cloud Computing is that it is completely compatible to multiprocessor technology. This is basically because of the increased importance of technologies like virtualization and parallel programming. Single processors can not handle immense pressure of the increasing demand of fast processing. To face the situation hardware designers started building multi core chips with the prediction that number of core chips will increase on an exponential rate in near future. So available computers have to be parallel with the increasing computer processing power. This is eased by Cloud virtualization techniques which allows the processing power to be utilized properly and efficiently .

Cloud Computing being a bit more economical then other hosting services so it will be more loved in developing countries and Data Centers Services India will try to bring Cloud Servers in their specifications as soon as possible. So lets understand the Total Cost Ownership on Cloud Computing. TCO for a data center is different from TCO for Cloud since Cloud is completely different from other services offered by data centers.

When you are running your business on some external cloud it is better to calculate the TCO required to run your business in external cloud as compared to the whole infrastructure. If the data center is insufficiently utilized then you will loss a lot of money. Mainly losses will be in Operation Exchange ( support staff, power, energy e.t.c.) and Capital Exchange (hardware requirements of the servers).

Compare Infrastructure with Cloud Costs

How do you face the situation of over or under utilization? What costs are associated in running unoccupied server? What are the possible risks associated with over utilization? The question of over utilization is tricky as one side each company want to grow their business and sell as much as they can thus increasing utilization. But on the other side it is believed to be a good option to save some capacity for your future developments or in any urgent situation.

If you have many colocation servers then this situation gets more complex. This situation cannot be measured in rupees or in any other currency as it depends on the costs and risk implicated in the case your service goes down.

Calculate the TCO for the whole infrastructure or for the part of your business which you are planning to be hosted on cloud. One you calculate TCO for your data center then only you can transform your business into utility computing model, which further can be compared to typical cloud services.

• Support and Security

• Facility system maintenance should be planned and long term.

• Whole infrastructure should be monitored properly.

• Disaster Management

Security and Support

People working in a colocation facility has a big impact on the customers. There are many colocation facilities which operate remotely for saving cost, but the one which are manually operated have a different impact on customers. If your colocation facility is maintained and monitored by an expert team, it will surely help in increasing a reliability and uptime guarantee. Just like monitoring support of your colocation facility should also be there 24X7. Best data centers have a 24X7 support. Having an on-site personnel is like investing money in good deal, not only it will give customers a good impact about the facility but also it will help you to maintain and monitor your servers and any problems can be fixed more swiftly. Having maintenance without security is  useless and anybody can cause damage or harm to your data center. Security is an important feature for business round the globe let it be health management or gaming. It is important to secure your server because these server store valuable information of your customers. On-site personnel also plays an important role in security just like support.

Monitoring of servers 24X7

Monitoring servers round clock help in increasing uptime, and if you want to make your data center services available round the clock monitor servers 24X7. A low cost colocation facility cannot fulfill the need of 24X7 monitoring of your servers and thus making your servers susceptible to various failures and other power issues. On the other hand a superior class colocation facility offers you a application and server monitoring programs. with a high class facility issues like overuse, performance deviation and fluctuations can be detected easily. It is difficult to notify customers about the problems without monitoring. Mostly data centers cut costs in server maintenance.

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.

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.
