A data center should be use to ensure the continuity of your business IT Infrastructure. Contracting the services of a data center to host your servers can ensure that your service would not be affected due to a power or internet outage. Essentially, a cloud data service is a remote version of a data center – located somewhere away from your company’s physical premises – that lets you access your data through the internet… A data center traditionally refers to server hardware on your premises to store and access data through your local network data center is that a data center refers to on-premise hardware while the cloud refers to off-premise computing. The cloud stores your data in the public cloud, while a data center stores your data on your own hardware. Data centers are simply centralized locations where computing and networking equipment is concentrated for the purpose of collecting, storing, processing, distributing or allowing access to large amounts of data. They have existed in one form or another since the advent of computers. Depending on the destination there are four different types of data centers, each designed for a specific business model and has its own operational problems and issues: Corporate data centers. Web hosting data centers, providing computer infrastructure as a service (IaaS) Data centers that provide TurnKey Solutions.
There is no requirement for a single data center, and modern businesses may use two or more data center installations across multiple locations for greater resilience and better application performance, which lowers latency by locating workloads closer to users.
Conversely, a business with multiple data centers may opt to consolidate data centers, reducing the number of locations in order to minimize the costs of IT operations. Consolidation typically occurs during mergers and acquisitions when the majority business doesn't need the data centers owned by the subordinate business.
Data center operators can also pay a fee to rent server space in a colocation facility. Colocation is an appealing option for organizations that want to avoid the large capital expenditures associated with building and maintaining their own data centers. Today, colocation providers are expanding their offerings to include managed services, such as interconnectivity, allowing customers to connect to the public cloud.
Because many providers today offer managed services along with their colocation facilities, the definition of managed services becomes blurry, as all vendors market the term in a slightly different way. The important distinction to make is this: Colocation -- The organization pays a vendor to house their hardware in a facility. The customer is paying for the space alone. Managed services -- The organization pays a vendor to actively maintain or monitor the hardware in some way, whether it be through performance reports, interconnectivity, technical support or disaster recovery.
Data centers are not defined by their physical size or style. Small businesses may operate successfully with several servers and storage arrays networked within a convenient closet or small room, while major computing organizations, such as Facebook, Amazon or Google, may fill an enormous warehouse space with data center equipment and infrastructure. In other cases, data centers can be assembled in mobile installations, such as shipping containers, also known as data centers in a box, which can be moved and deployed as required.
Although almost any suitable space could conceivably serve as a "data center," the deliberate design and implementation of a data center requires careful consideration. Beyond the basic issues of cost and taxes, sites are selected based on a multitude of criteria, such as geographic location, seismic and meteorological stability, access to roads and airports, availability of energy and telecommunications and even the prevailing political environment.
Once a site is secured, the data center architecture can be designed with attention to the mechanical and electrical infrastructure, as well as the composition and layout of the IT equipment. All of these issues are guided by the availability and efficiency goals of the desired data center tier.
Data center designs must also implement sound safety and security practices. For example, safety is often reflected in the layout of doorways and access corridors, which must accommodate the movement of large, unwieldy IT equipment, as well as permit employees to access and repair the infrastructure.
Fire suppression is another key safety area, and the extensive use of sensitive, high-energy electrical and electronic equipment precludes common sprinklers. Instead, data centers often use environmentally friendly chemical fire suppression systems, which effectively starve a fire of oxygen while mitigating collateral damage to the equipment. Because the data center is also a core business asset, comprehensive security measures, like badge access and video surveillance, help to detect and prevent malfeasance by employees, contractors and intruders.
The core components of a data center –
Data center design includes routers, switches, firewalls, storage systems, servers, and application delivery controllers. Because these components store and manage business-critical data and applications, data center security is critical in data center design. The data centers are 250 feet long, 72 feet wide, 16 feet deep. The following are common components of a data center –
Computing Hardware, Computing units, data storage devices and other hardware deployed by customers or provided as a service by the data center.
Any entity that generates or uses data has the need for data centers on some level, including government agencies, educational bodies, telecommunications companies, financial institutions, retailers of all sizes, and the purveyors of online information and social networking services such as Google and Facebook. Data center infrastructure refers to the core physical or hardware-based resources and components – including all IT infrastructure devices, equipment and technologies – that comprise a data center. Importance of Data Centers in Our Lives. Most of the things in every segment of human activity such as energy, lighting, telecommunications, internet, transport, urban traffic, banks, security systems, public health, entertainment and even our physical integrity are controlled by data centers.
