Why Cloud Computing?

Feb 25

Posted by in Data Centers India | No Comments

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 .

Feb 10

Posted by in Data Centers India | No Comments

Virtual Private Servers (VPS) are one of the most kind of servers in the world. After dedicated hosting VPS hosting is the one most preferred by the clients.  Dedicated server is divided into several virtual slices and each of that slice acts like a small dedicated server. Users of one virtual server didn’t mess with virtual servers on the same dedicated server. Cloud hosting is another famous hosting package, it is considered as future of web hosting. In Cloud hosting multiple physical servers are connected in pool like formation, hosting resources are supplied on demand. From the customers point of view this whole pool looks like a single dedicated server with the resources as CPU, Disk space, RAM equal to hundreds of physical servers. The customers are charged on the basis of what they use, most like a modern electricity billing. Cloud hosting is definitive cost effective approach in hosting that’s why it is considered as future. Cloud Virtual Server is a combination of two best technologies in hosting world. A Cloud Virtual Private Servers are not hosted on a single dedicated server just like traditional VPS, instead it is hosted within cloud servers. Each physical server provides resources to each of the VPS created. Cloud VPS are considered as more reliable than normal because it is not attached to a single server. Slicing is done by all the servers thus making it failure proof hosting solution. A Cloud VPS server can be easily created with complete automation. Whole process of assigning and identifying cloud resources and creating VPS is done by central OS. All you have to do is few simple clicks and step sand your Cloud VPS will be ready to use. Taking this point into consideration many hosting providers charge their customers on a hourly basis.

Importance of Data Center’s Location

Feb 9

Posted by in Data Centers India | No Comments

Most ideal locations for a data center is the one which have sufficient supply of electricity, near to vendor market and generally a cold place. Perfect site for Data Centers location is the one which is not prone to flood or any other natural calamities. Also it is better to avoid locations near to any air or water contaminating industries. One small but important point is to avoid tress which produce sap. If you are near to a cold lake or river which has no possibilities of harming the data centers than you can use the water as cooling agent thus total cooling cost will be reduced. All these points are important when you are building a data center. Most if the time data centers are used for the following purposes:

  • Data Storage
  • Application Hosting
  • Web 2.0 services
  • Streaming Video Source

To provide the above requirements of customers you need to think about latency and the demand of bandwidth. Bandwidth is more important than data storage. Data storage units which include normal servers as well as colocation servers, are often placed far away from each other for the reason if something disastrous happens simultaneous damage can be saved. But they shouldn’t be placed very far because there is need of synchronous file replication. Data centers which are totally dedicated to provide application hosting have all type of provision for the customers those who are running applications which requires heavy bandwidth like mail services. These kind of applications need well-organized transmission protocols. Some other applications where even a delay of millisecond can damage millions require high latency, like market data feeds for financial services. High latency is the requirement of the data center near to these business as they can’t afford delay. Web 2.0 applications are the strangest one as they include so many types, web storage, web services like security and confirmation. However only requirement of web 2.0 applications is tremendous high performance of connectivity out and inside data center.

TCO for Cloud Computing

Feb 6

Posted by in Data Centers India | No Comments

We already saw what is Total Cost Ownership of a Data Centers. Cloud Computing a new kind of technology which is being considered as the future of hosting and webs world. Cloud Hosting has got many advantages over other traditional hosting services like VPS hosting, Shared Hosting or dedicated server hosting. Cloud Computing being a bit more economical then other hosting services so it will be more loved in developing countries and data centers in country like 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.

Three Steps To Secure your Data Center

Jan 12

Posted by in Data Centers India | No Comments

Its Cloud Computing which bought server-oriented, virtualization and new Internet applications. With Cloud Computing Data Centers are now more active with flexible boundaries. However this change towards Cloud Computing also added new levels of intricacies. IT managers now have to work more hard in order to secure equipments in Data Center so that precious data of the customers will be safe from spiteful attacks. 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.

Evolution of Data Centers

Dec 22

Posted by in Colocation Services India | No Comments

Most of use believe that Data Centers came into existence all through late 90’s in the dot com boom. But the true fact is that data centers are as old as early computer era previously known as private computer rooms or dedicated computer rooms. Since early computer systems were large, complex room sized machines which required of a lot of space and controlled environment. These requirements of maintenance and large rooms led to the evolution of dedicated computer rooms which later evolve into Data Centers. Also since the computer business was new at that time security was big concern. Machines were extremely expensive in that era so they have to be placed in separate rooms. Early computers was only used for large and important civilian business ventures military purposes. As we all know how secure civilian business and military operations are that’s why the machines are kept in secured rooms. One more factor that played an important part in the evolution of data centers was the need of cooling these giant computers cool. Computers of that time consume large power just according to their size and chances of overheating were quite frequent. So in separate rooms particular arrangements can be made to keep the machines cool and prevent any loss from overheating. Size of the cables was also huge because of the size of these computers. N number of cables connecting various parts of the huge computers needed to be organized. All these points lead to the creation of some early data center standards, which we all know how much they are important. Cables trays were created to manage the cables and Racks were planned to house the equipments. In order to accommodate early computers floors were also elevated.

Evolution of Data Center-3

Later during the 80’s computer industry experienced the boom of microcomputer era. Flowing in the excitement of this new technology nobody thought about controlled environment required and machines were installed everywhere. Organizing the machines grew complex with time and lost of data became a major worry, and this lead to the development of information technology teams. Work for these teams was to install and maintain early microcomputers. However this was not the final and permanent solution and Data Centers were created. As computers were shifted to dedicated rooms and more and more teams were set up for the maintenance, hierarchical designs were also suggested for these rooms. And for the first time the word Data Center was coined. Importance of the Data Center grew as the dot com bubble evolved and companies began to understand the significance of having Internet. In order to have fast and reliable communication and connectivity. Internet also gave companies to have the capability of 24×7 presence. These requirements resulted in the construction of large data facilities and initially these facilities were called as “Internet Data Centers.” These facilities were used to operate computer systems and install new systems within the company. However some points made these data centers extremely expensive like equipment requirement, physical space and skilled staff. Not all companies were able to operate a large data center. Today’s Scenario is different and now even small companies can enjoy the services of Data Center. Constructing and operating a data center is a extensively recognized industry. Disaster recovery plans helped in enhancing the reliability and uptime guarantee of the companies.
