Data centers are network-integrated all-in-one application centric remote server ecosystem that stores, manages, and processes huge amount of valuable organization data primarily coming from varied digital media sources.

1. Data Center – An All-In-One Application Ecosystem
with Big Data Managing Certifications
Managing and processing data with the traditional data processing approaches is the
toughest job. Here is why to make things simpler, the data centers have emerged, which is
an all-in-one application centric ecosystem that stores, processes and manages huge
quantities of organization data.
Every day, around 2.5 quintillion bytes of data is created in the corporate firms. This data
comes from everywhere such as sensors, posts to social media sites, digital pictures and
videos, purchase transaction records, and cell phone GPS signals, etc. The quantity in which
data is created each day makes it difficult or complex to store and process these data sets
via the traditional approaches. Often, the term big data is used in context. You might be
wondering what is big data? Well!! Big data refers to huge amount of data that is beyond
the processing capability of traditional data management system to manage and analyze the
data in a specified time span. Big data comes from many sources, some of them are digital
media, online transaction records, cell phone signals, etc. It is quite impossible to process
big data using the traditional data management system. This is the reason, the data centers
came into existence. Now, what are data centers? How are they helpful in processing big
data?
Data Centers – Definition
Data centers are network-integrated all-in-one application centric remote server ecosystem
that stores, manages, and processes huge amount of valuable organization data primarily
coming from varied digital media sources. In basic terms, Data centers are the
infrastructure supporting the application ecosystem. These all-in-one application systems of
data centers are efficient enough to manage cloud big data efficaciously. The data center
infrastructure is designed and built with complex set of systems that make it capable for
processing great amount of data files of an organization coming from different digital
routes. The amount of data stored, processed, and managed by data centers is
approximately more than several quintillion bytes of data.

2. Big Data Certification and the Tier 3 Data Center Model
The number of big data certifications is increasing day by day. The field of big data is
expanding every day. Data centers are at the core of processing big data and so the
certification courses dealing with data centers are also covering the aspects of big data as
well. There are several notable organizations around the world that offer varied kinds of
data center courses and among few of those courses carry big data certifications. Through
big data certifications acquired through comprehensive data center courses helps handle the
holistic and dynamic ecosystem of data centers carrying huge amount of big data.
In order to handle the tier 3 data center model, one needs to have big data certification as
that allows the technician to understand the holistic and dynamic system of the application.
You might be wondering what is tier 3 data center model? In basic terms, tier 3 data center
is a location with redundant and dual powered servers, storage, network links, and other IT
components. It is one of the most commonly used data center tiers, where IT components
are powered with multiple, active and independent sources of power and cooling resources.
A tier 3 data center is also known as a level 3 data center. A tier 3 data center model
combines and exceeds features and capabilities of tier 1 and tier 2 data centers but with
redundant capacity and data center infrastructure components. It is the third level/tier of
data centers introduced by the uptime institute.
Like a tier 2 data center, IT components can be replaced or removed without interrupting
routine data center operations. With the redundant and always active power supply, there is
minimal planned and unplanned downtime. It guarantees 99.982 percent availability wit h a
fractionally of less than two hours downtime per year.
This is why proper certifications are essential to handle these complex systems efficaciously.
