Four Primary Types of Data Centers

What Is a Data Center and What Does it Contain?

At its most fundamental level, a data center is a physical establishment that enterprises employ to store their essential data and applications. The architecture of a data center is built on a system of computer and storage tools that support the deployment of integrated data and applications. Storage systems, routers, switches, firewalls, servers and application-delivery devices are the vital ingredients of a data center's architecture.


What Characterizes a Contemporary Data Center?

Contemporary data centers differ significantly from their predecessors. Conventional on-premises dedicated servers have been replaced by network systems that handle applications and operations spanning pools of physical infrastructure and in a multi-cloud system.

Data is available and is linked across many data centers, the apex, and public and private clouds in the current period. The data center must be capable of communicating with these different on-premises and cloud-based locations. Even the public cloud comprises multiple data centers. When apps are hosted in the cloud, they use the cloud provider's data center resources.


Benefits of Data Center

Data centers in corporate IT are intended to serve business applications and operations such as:

  • Email and file distribution
  • Client relationship management (CRM)
  • Artificial intelligence, big data and machine learning
  • Virtual desktops, collaboration and communication services
  • Enterprise resource planning (ERP) and databases
  • Productivity-enhancing applications

Features of Data Centers

Routers, switches, firewalls, storage systems, servers, and application delivery devices are included in a data center design. Because these systems hold and handle business-critical applications and data, data center design must prioritize safety. Together, they supply:

  • The network infrastructure: This connects end-user locations to real and virtual servers, data center applications, memory, and external connection.

  • The infrastructure for storing data. Data is the contemporary data center's fuel. This precious commodity is held in storage systems.
  • Computing assets: Programs are the data center's engines. These servers offer processing, local storage, memory and network access programs.

How Do Data Centers Work?

Typically, data center resources are delivered to safeguard the functionality and security of the whole data center system.

  • Information security equipment. These safeguards include a firewall and intrusion detection and prevention systems.
  • Application delivery assurance. These strategies provide application resilience and accessibility via minimum downtime and load balancing to maintain application performance.

The Components of a Data Center

Components of a data center necessitate an extensive architecture to accommodate the software and hardware of the center. This includes electrical components, uninterruptible power supplies (UPS), ventilation, cooling equipment, fire protection systems, emergency generators and external internet connectivity.

The Requirements for Data Center Infrastructure

ANSI/TIA-942 is the most commonly recognized platform for data center planning and system infrastructure. It provides ANSI/TIA-942-ready accreditation criteria, which ensures compliance with one of four kinds of data center tiers rated for duplication and failure tolerance levels.

Tier 1: Basic site infrastructure. A Tier 1 data center offers modest physical event protection. It has single-capacity elements and a single, non-redundant channel of distribution.

Tier 2: Infrastructure components with redundant capacity. This data center provides enhanced physical hazard safety. It consists of several components with duplicate capacity and a single, non-redundant channel of distribution.

Tier 3: Infrastructure maintainable concurrently. This data center offers protection against most mechanical occurrences, with redundant elements and various independent distribution channels. Each component can be uninstalled or changed without negatively impacting end-user services.


Tier 4: Fault-tolerant site infrastructure. This data center has the best error detection and redundancy available. Devices with duplicate capacity and numerous independent distribution pathways permit simultaneous maintenance and a single failure anywhere in the installation without generating downtime.

Data Center Design Variations

There are different data centers and business systems available. Their classification relies on whether they are controlled by a single or multiple businesses, how they fit (if at all) into the architecture of other data centers, the storage and computing capabilities they employ, and even their power efficiency. Four primary types of data centers exist:


Enterprise Data Centers

These are constructed, owned, and managed by businesses and tailored to their customer base. They are typically located on the major site.

Cloud Data Centers


In this kind of off-site data center, a cloud services provider hosts data and applications.

Colocation Data Centers

In colocation ("colo") data centers, a corporation leases space within an off-site data center controlled by a third party. The colocation data center houses the architecture, including the facility, ventilation, connectivity, and protection, while the company supplies and operates the elements, such as servers, memory, and firewalls.


Managed Services Data Centers

These data centers are maintained on behalf of a firm by a third party (or managed services provider). Instead of purchasing the equipment and facilities, the corporation leases them.

dvancement of Architecture: From Legacy Systems to Cloud Apps

In the past 65 years, the technology architecture has seen three significant evolvement phases:

The first phase witnessed the transition from commercial legacy systems to x86-based, on-premises systems administered by corporate IT departments.

In a second wave, application-supporting infrastructure was virtualized extensively. It increased resource usage and workload movement across physical infrastructural pools.


The third phase occurs in the present, where there is a transition to hybrid cloud, cloud-native and cloud. The latter describes cloud-born applications.

Network of Distributed Software


This growth has led to the development of cloud applications. Here, applications and data are dispersed across diverse systems, interconnected and linked via communication networks and compatibility standards to operate as a unified framework. It has resulted in the term data center being applied to the department responsible for these technologies regardless of their physical location.

Businesses can construct and maintain their own hybrid cloud computing systems, lease space in colocation centers (colos), leverage combined computation and storage solutions, or employ public cloud-based infrastructure. The result is that apps no longer exist in a single location. They function in numerous public and private clouds, controlled solutions, and conventional settings. In this multi-cloud age, the data center has expanded and become more complicated to facilitate a positive user experience.
