<blockquote>
• India Data Center Market Size which is rapidly increasing with increasing requirement for data storage, is said to cross $4.5 Billion by 2025 – Arizton
• Over $2 billion cumulative revenue opportunity for data center construction contractor through India market during 2020-2025, as few states like Telangana and
Maharashtra are already taking FDI for data centres.
• As the competition among states of India for investment into data centres grows, Maharashtra leads with 60% market shares in investment.
• Existing data centers in India have majorly installed racks of 42U and 47U configuration. Hyperscale build-to-suit development to support deployment of OCP-rack
architecture, which will, in turn, is likely to increase adoption of 48U racks.
• Tech giants like Oracle, and the companies from recent news GOOGLE and MICROSOFT, to open their Cloud region and Azure platform in India by end of 2020.
<strong>What defines a modern data center?</strong>
Modern data centers are very different than they were just a short time ago. Infrastructure has shifted from traditional on-premises physical servers to virtual networks
that support applications and workloads across pools of physical infrastructure and into a multicloud environment. In this era, data exists and is connected across multiple
data centers, the edge, and public and private clouds. The data center must be able to communicate across these multiple sites, both on-premises and in the cloud. Even the
public cloud is a collection of data centers. When applications are hosted in the cloud, they are using data center resources from the cloud provider.
<strong>Why are data centers important to business?</strong>
In the world of enterprise IT, data centers are designed to support business applications and activities that include:
Email and file sharing
Productivity applications
Customer relationship management (CRM)
Enterprise resource planning (ERP) and databases
Big data, artificial intelligence, and machine learning
Virtual desktops, communications and collaboration services
<strong>What are the core components of a data center?</strong>
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. Together, they provide:
Network infrastructure. This connects servers (physical and virtualized), data center services, storage, and external connectivity to end-user locations.
Storage infrastructure. Data is the fuel of the modern data center. Storage systems are used to hold this valuable commodity.
Computing resources.
<strong>Applications are the engines of a data center. These servers provide the processing, memory, local storage, and network connectivity that drive applications.
How do data centers operate?</strong>
Data center services are typically deployed to protect the performance and integrity of the core data center components.
Network security appliances. These include firewall and intrusion protection to safeguard the data center.
Application delivery assurance.
To maintain application performance, these mechanisms provide application resiliency and availability via automatic failover and load balancing.
<strong>What is in a data center facility?</strong>
Data center components require significant infrastructure to support the center's hardware and software. These include power subsystems, uninterruptible power supplies (UPS),
ventilation, cooling systems, fire suppression, backup generators, and connections to external networks.
<strong>What are the standards for data center infrastructure?</strong>
The most widely adopted standard for data center design and data center infrastructure is ANSI/TIA-942. It includes standards for ANSI/TIA-942-ready certification, which ensures
compliance with one of four categories of data center tiers rated for levels of redundancy and fault tolerance.
Tier 1: Basic site infrastructure. A Tier 1 data center offers limited protection against physical events. It has single-capacity components and a single, nonredundant
distribution path.
Tier 2: Redundant-capacity component site infrastructure. This data center offers improved protection against physical events. It has redundant-capacity components and a single,
nonredundant distribution path.
Tier 3: Concurrently maintainable site infrastructure. This data center protects against virtually all physical events, providing redundant-capacity components and multiple
independent distribution paths. Each component can be removed or replaced without disrupting services to end users.
Tier 4: Fault-tolerant site infrastructure. This data center provides the highest levels of fault tolerance and redundancy. Redundant-capacity components and multiple independent
distribution paths enable concurrent maintainability and one fault anywhere in the installation without causing downtime.
<strong>Types of data centers</strong>
Many types of data centers and service models are available. Their classification depends on whether they are owned by one or many organizations, how they fit (if they fit) into
the topology of other data centers, what technologies they use for computing and storage, and even their energy efficiency. There are four main types of data centers:
42950650-new-600x338
Enterprise data centers
These are built, owned, and operated by companies and are optimized for their end users. Most often they are housed on the corporate campus.
cloud-42861523-600x338
Managed services data centers
These data centers are managed by a third party (or a managed services provider) on behalf of a company. The company leases the equipment and infrastructure instead of buying it.
42950736-fc-600x338
Colocation data centers
In colocation ("colo") data centers, a company rents space within a data center owned by others and located off company premises. The colocation data center hosts the infrastructure:
building, cooling, bandwidth, security, etc., while the company provides and manages the components, including servers, storage, and firewalls.
public-600x338
Cloud data centers
In this off-premises form of data center, data and applications are hosted by a cloud services provider such as Amazon Web Services (AWS), Microsoft (Azure), or IBM Cloud or other
public cloud provider.

Infrastructure evolution: from mainframes to cloud applications
Computing infrastructure has experienced three macro waves of evolution over the last 65 years:
The first wave saw the shift from proprietary mainframes to x86-based servers, based on-premises and managed by internal IT teams.
A second wave saw widespread virtualisation of the infrastructure that supported applications. This allowed for improved use of resources and mobility of workloads across pools
of physical infrastructure.
The third wave finds us in the present, where we are seeing the move to cloud, hybrid cloud and cloud-native. The latter describes applications born in the cloud.
<strong>Distributed network of applications</strong>
This evolution has given rise to distributed computing. This is where data and applications are distributed among disparate systems, connected and integrated by network services and
interoperability standards to function as a single environment. It has meant the term data center is now used to refer to the department that has responsibility for these systems
irrespective of where they are located. Organizations can choose to build and maintain their own hybrid cloud data centers, lease space within colocation facilities (colos), consume
shared compute and storage services, or use public cloud-based services. The net effect is that applications today no longer reside in just one place. They operate in multiple public
and private clouds, managed offerings, and traditional environments. In this multicloud era, the data center has become vast and complex, geared to drive the ultimate user experience.
