The companies/organization who are maintaining data centres are an absolutely crucial challenge. When I started studying the data centres, I had seen Microsoft, Google, Facebook and Day in the life of a data centre videos. Apart from it, I went through very few articles.
Interestingly, the security level seems enormous. Precisely, I saw a video on Google Data Center Security: six Layers Deep. Technicians look notably, professionals. Because in a Day in a life of data centre video they review and change several hard drives and doing repairs shows their dedications.
Apart from watching videos, if I had an opportunity to visit any data centre, I will go. I would argue, it doesn’t matter which data centre you have a visit. It all matters with the experience you are gonna gain in the data centre by looking at the way they work.
Finally, the investment made to build the data centre is gigantic. With humility, we must pay respect to the professionals who are in the data centre.
I’m gonna combine the two articles about the data centre. I would say those two says fair view about the data centre.
I’m gonna paste the source link down below. I sincerely encourage you all to visit further.
What Is a Data Center
At its simplest, a data center is a physical facility that organizations use to house their critical applications and data. A data center’s design is based on a network of computing and storage resources that enable the delivery of shared applications and data. The key components of a data center design include routers, switches, firewalls, storage systems, servers, and application-delivery controllers.
What defines a modern data center?
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.
Why are data centers important to business?
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
What are the core components of a data center?
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. 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?
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.
What is in a data center facility?
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.
What are the standards for data center infrastructure?
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.
The Role of the Data Center
Data centers are an integral part of the enterprise, designed to support business applications and provide services such as:
- Data storage, management, backup and recovery
- Productivity applications, such as email
- High-volume e-commerce transactions
- Powering online gaming communities
- Big data, machine learning and artificial intelligence
Today, there are reportedly more than 7 million data centers worldwide. Practically every business and government entity builds and maintains its own data center or has access to someone else’s, if not both models. Many options are available today, such as renting servers at a colocation facility, using data center services managed by a third party, or using public cloud-based services from hosts like Amazon, Microsoft, Sony and Google.
The primary elements of a data center break down as follows:
- Facility – the usable space available for IT equipment. Providing round-the-clock access to information makes data centers some of the world’s most energy-consuming facilities. Design to optimize space and environmental control to keep equipment within specific temperature/humidity ranges are both emphasized.
- Core components – equipment and software for IT operations and storage of data and applications. These may include storage systems; servers; network infrastructure, such as switches and routers; and various information security elements, such as firewalls.
- Support infrastructure – equipment contributing to securely sustaining the highest availability possible. The Uptime Institute has defined four tiers of data centers, with availability ranging from 99.671% to 99.995%. Some components for supporting infrastructure include:
- Uninterruptible Power Sources (UPS) – battery banks, generators and redundant power sources.
- Environmental control – computer room air conditioners (CRAC); heating, ventilation and air conditioning (HVAC) systems; and exhaust systems.
- Physical security systems – biometrics and video surveillance systems.
- Operations staff – personnel available to monitor operations and maintain IT and infrastructure equipment around the clock.
Data centers have evolved significantly in recent years. As enterprise IT needs continue to move toward on-demand services, data center infrastructure has shifted from on-premises servers to virtualized infrastructure that supports workloads across pools of physical infrastructure and multi-cloud environments. There is an expression these days: The modern data center is where your workloads are.
