The Evolution of Cloud Data Center

Data centers come in various sizes, from a single isolated server room to large clusters of buildings spread across a large area. Still, they all have one feature in common: they are vital business assets where businesses frequently invest in and implement the most recent developments in compute, data center networking, and storage technologies.


The contemporary data center has changed from being a place where an on-premises architecture was housed to one that links on-premises systems with cloud architecture known as cloud data center, where apps, networks and workloads are virtualized across many public and private clouds.



● Enterprise data centers are often built and utilized by a single enterprise for internal uses. These are typical among multinational tech companies.
● Colocation data centers serve as a type of rental property where a data center's space and resources are made available to those who are interested in renting them.
● Managed service Data centers directly serve clients by providing services like computation, data storage, and other elements.
● Distributed cloud data centers are occasionally made available to consumers with the aid of a separately managed service provider.

Data Center Evolution


The simplicity with which a virtual cloud may be ramped down or up with just a few clicks is one of the primary arguments for migrating to the cloud. Contemporary data centers have traffic flow management software called software-defined networking.  Solutions for Infrastructure as a Service that are hosted on both public and private clouds enable the construction of systems on request. Platform as a Service and container technology is quickly accessible when new apps are required.


Although more organizations are migrating to the cloud, not all of them are prepared to do so. For the first time, businesses allegedly spent more on cloud computing services in 2019 than on physical hardware. According to 58% of businesses in a survey, most workloads are still housed in corporate data centers because public cloud platforms are not transparent, accountable, or visible.


Data Center Architecture Components


storage, compute, and network are the three main categories of components found in data centers. But in a contemporary DC, these elements merely represent the tip of the iceberg. Support infrastructure is crucial to fulfill an enterprise data center's service level commitments.


Data Center Storage


Data centers house a lot of private information for both their own needs and those of their clients. The amount of storage space available for local, remote, or combined data backup rises as storage media costs decline. Data access times are getting faster because to developments in non-volatile storage. Additionally, software-defined storage solutions improve staff productivity when operating a storage system, just like with everything else that is software-defined.


Data Center Computing


The servers are the brains of a data center. Applications that run on servers may use processing and memory that is distributed among numerous distant nodes using virtual, distributed, physical, containerized, or edge architectures. In data centers, the right processors must be employed; general-purpose CPUs, for instance, might not be the best choice for solving deep learning and artificial intelligence difficulties.


Data Center Networks


Datacenter network hardware, including firewalls, routers, switches, and cables, is used to connect servers to one another and to the outside world. They can handle a lot of traffic when they are properly designed and configured without losing performance. A center aggregate layer connects the core layer to the access layer, which is where the servers are placed, and central switches at the data center's edge connect it to the Internet. Software-defined architecture and hyperscale network security advances have given on-premises networks the scalability and agility of cloud networks.


Data Center Support Infrastructure


Data centers, regarded as vital assets, are protected by a solid and dependable support infrastructure comprising fire suppression systems, cooling equipment and ventilation, backup generators, uninterruptible power supplies (UPS), building surveillance systems, and power subsystems.


Data center design, building, and maintenance are aided by industry standards provided by groups like the Telecommunications Industry Association (TIA) and the Uptime Institute. The Uptime Institute, for example, describes these four tiers:



● Tier I: Minimum capability; a UPS is required.
● Tier II: Redundant capacity with the addition of redundant power and cooling.
● Tier III: Concurrently maintainable and guarantees that any part can be removed from service without disrupting production.
● Tier IV: Fault-tolerant, allowing any manufacturing capacity to be protected from any form of failure.
