The document discusses what a datacenter is and provides details about their evolution and types. It defines a datacenter as a facility that stores, manages, deploys, and monitors organizations' massive data, information, and IT applications at a centralized location to ensure business continuity. It describes how datacenters have evolved from traditional "siloed" datacenters in the early 1990s to today's more flexible software-defined datacenters. The document also outlines the four levels of datacenters as defined by the Telecommunications Industry Association, ranging from basic level 1 server rooms to highly redundant level 4 datacenters designed to continuously operate during power outages.

1. What Is A
Datacenter?
A data center is an infrastructure facility which stores,
manage, deploy and monitors organizations massive data,
information and IT applications at a centralized location
that ensures business continuity.

2. Datacenters
Datacenters today have become an integral part of our life. Datacenters, as the name suggests,
is a facility where organizations store, deploy, manage and monitor their massive amount of
industrial/corporate crucial data and information. It comprises of computer systems &
hardware such as racks, storage & associated devices, computers, networks, backup, power
supply, and security etc.
Businesses, Industry’s and organizations are generating a massive amount of data and
information be it structured or unstructured and it is a continuous recurring process It is very
difficult for these businesses to store, deploy, manage and monitor this data & information on
their own infrastructures this is where Datacenters come into the picture. A Datacenter service
provider stores, manage, maintain & secures the data on behalf of the organizations it is a
Datacenter service providers responsibility to keep the data and information along with the
company’s applications available and updated as and when they are required with zero or
negligible downtime.

Definition of Datacenter
“A data center is an infrastructure facility which stores, manage, deploy and
monitors organizations massive data, information and IT applications at a
centralized location that ensures business continuity.”
Evolution of Datacenters
The evolution of the computer has its roots in the early 19th century when
Charles Babbage, considered to be the father of computers invented the
first mechanical computer. The first computers were quite similar to today’s
Datacenters they were known as traditional Datacenters or ‘siloed’
Datacenters in the early 90’s. Traditional Datacenters or siloed Datacenters
offered reliability, & flexibility though they were astonishingly slow, an
organization would take months to deploy new applications with traditional
Datacenters.

4. Evolution of Cloud Technology
Virtualisation technology which came into existence between 2003-
2010 played a major role in the evolution of today’s Datacenters. It
enables us to virtualize and pool resources of computing such as
Storage, RAM, ROM, Network etc. to create more flexible, reliable, and
resourceful infrastructure. Thanks to Cloud Computing we are now
able to better utilize the resources with greater flexibility, reliability &
Speed.

5. Software-defined Datacenters (SDDC) / Software-Led
Infrastructure (SLI)
Virtualisation of the siloed Datacenters does enable flexibility and reliability on traditional
Datacenters but had detrimental impacts on storage and network components. Server
virtualization wasn’t the perfect solution but a stepping stone for an ultimate solution. Server
virtualisation enabled better utilisation of resources in an ideal situation though it had a
shortfall, as, what if an application on a shared resource utilises more resources than that of
the other applications relying on the same resources these applications will witness a shortfall
of computing resources & it will void the complete SLA of 100% uptime between the
organisations and the service provider. This is the part when software-defined virtualization or
Software-Led Infrastructure (SLI) came into the picture. This gave total control on resource
utilization via software’s giving a centralized control over deployment, automation, regulations,
provisioning & configuring with the aid of software. SLI also enabled us to allocate resources
as per the applications demands automatically scaling resources up and down as and when
required handling dynamic demands & reliving IT burdens of the organizations and it’s also
cost-effective as the organizations only have to pay for the resources they have utilized.
According to a survey by Right scale 2017, 95% of respondents are using cloud computing
some or the other way.

6. Datacenter Types
The Telecommunications Industry Association is a trade association accredited
by ANSI (American National Standards Institute). In 2005, it published ANSI/TIA-
942, Telecommunications Infrastructure Standard for Data Centers, which defined
four levels of data centers in a thorough, quantifiable manner.TIA-942 was
amended in 2008, 2010, 2014 and 2017. TIA-942: Data Center Standards Overview
describes the requirements for the data center infrastructure. The simplest is a
Level 1 data center, which is basically a server room, following basic guidelines for
the installation of computer systems. The most stringent level is a Level 4 data
center, which is designed to host the most mission-critical computer systems,
with fully redundant subsystems, the ability to continuously operate for an
indefinite period of time during primary power outages.

7. ▸You might not know yet but yes, it is a fact Datacenters are or have become an integral part of our
lives or it affects our lives in some or the other ways & Datacenters today have evolved far more
than just stacks of servers, here are some interesting facts about Datacenters.
▸Datacenters accounts to 17% of carbon footprints of the global information and communication
technology sector.
▸For every watt of computer power consumed by a Datacenter, it takes another watt to cool it
▸You need a whole power plant just to cool a Datacenter.
▸A large Datacenter has the capacity to use as much electricity as a small town.
▸Every Datacenter has to be uptime certified.
▸Google has around 15 Datacenters all over the world with 9,00,000 servers and Google alone
roughly accounts for 0.013% of the worlds energy use.
▸Facebook has around 6 Datacenters across the world with 60,000 servers and consumes around
approx. 678m kWh of energy every year.
▸Amazon has Datacenters at 7 locations in the world with 1,58,000 servers and their 30 million
customers streams around 40 PB/Month of data.
▸Microsoft has around 20 facilities across the world with 1,00,000 servers and there southern
Virginia Datacenter costs a whopping $1 Billion.
