  3. Data Center • A data center refers to any physical space (a building, a group of buildings, a building’s dedicated space etc.) that is used to house an organization’s IT infrastructure, critical applications and data. It has a network of computing and storage resources which are used to deliver shared applications and data. Storage systems, servers, firewalls, routers, application-delivery controllers are an essential part of any data center. • Data centers serve the purpose of securing resources that have to do with information technology along with ensuring the least amount of downtime.

  4. Need for Data Centers The existence of data centers helps to achieve the following- • Efficient storage and management of data • Decrease in barriers with regard to internal operations • Higher Margins • Enhanced data security • Centralized management that facilitates better decision making.

  5. Main Components of a Data Center • Network Infrastructure- It is meant to connect both physical and virtual servers, services of the data center, storage etc. to the end users. • Storage Infrastructure- It stores as well as manages data safely. • Computing Resources- These resources (servers) enable processing of applications. To digress, servers are used by web hosting companies as well. These servers store the data of websites in order to make the websites accessible over the Internet. The best web hosting companies are usually referred to with terms such as the “Best Website Hosting Company”, the “Best Windows Hosting Company”, the “Best Linux Shared Hosting Company” etc.

  7. Data Center Operations Data center opertions consist of the workflows and the systems that enable a data center to run. These include the following- • Installing as well as maintaining network resources • Monitoring systems that have to do with power and cooling • Maintaining security of the data center

  8. Tiers of Data Centers The four tiers of data centers are mentioned below- • Tier 1: It is usually used by small-sized businesses. There are no assured built-in redundancies in it for the purpose of ensuring optimal uptime. A tier 1 data center’s average downtime in a year is 28.8 hours. • Tier 2: Certain redundancies are introduced in it by the colocation provider. Moreover, partial redundancies are usually built in for the purpose of ensuring the availability of power and cooling for supporting operations. Its annual downtime is approximately 22 hours. • Tier 3: It provides better protection against issues that have to do with power and cooling. A tier 3 data center’s annual downtime is 1.6 hours. Such a data center makes use of N+1 fault tolerenace. This ensures up to 72 hours of protection against a power outage. • Tier 4: An annual uptime of 99.995% is provided by a tier 4 data center. Its annual downtime is as low as 26.3 minutes which makes it a top choice for enterprises. A tier 4 data center has 2n+1 redundant infrastructure and it assures 96 hours of protection against a power outage.

  9. Types of Data Centers The classification of data centers depends on certain factors, such as, the number of owner organizations, computing and storage technologies that have been used, the way these data centers fit into the topology of other data centers, their energy efficiency etc. The four main types of data centers are mentioned below, in no particular order. • Enterprise Data Centers • Managed Services Data Centers • Colocation Data Centers • Cloud Data Centers • These are described in the following slide.

  10. Different types of Data Centers Explained The above-mentioned types of data centers are explained below, in brief. • Enterprise Data Centers- These data centers are owned, built and operated by enterprises and are usually housed on a corporate campus. These are optimized for the end users. • Managed Services Data Centers- This type of a data center is managed by a third party. The business that uses it leases the required infrastructure rather than buying it. • Colocation Data Centers- In this type of a data center, a business rents space in a data center that is not owned by it and which is located off the business’ premises. Such a data center hosts the infrastructure whereas the business provides and manages all the components which include servers, firewalls etc. • Cloud Data Centers- In this type of a data center, the applications and data are hosted by a particular cloud services provider. It is an off-premise data center.
