Data Center

• A data center refers to any physical space (a
  building, a group of buildings, a buildings
  dedicated space etc.) that is used to house an
  organizations 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.

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.

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.

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

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 centers 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 centers annual downtime is 1.6
  hours. Such a data center makes use of N1 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
  2n1 redundant infrastructure and it assures 96
  hours of protection against a power outage.

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.

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.
