		+	== Data Center Architecture<ref>[https://www.ibm.com/topics/data-centers Data Center Architecture]</ref> ==
		+	Most modern data centers—even in-house on-premises data centers—have evolved from traditional IT architecture, where every application or workload run on its own dedicated hardware, to cloud architecture, in which physical hardware resources—CPUs, storage, networking—are virtualized. Virtualization enables these resources to be abstracted from their physical limits and pooled into capacity that can be allocated across multiple applications and workloads in whatever quantities they require.
		+
		+	Virtualization also enables software-defined infrastructure (SDI)—infrastructure that can be provisioned, configured, run, maintained, and ‘spun down’ programmatically, without human intervention.
		+
		+	The combination of cloud architecture and SDI offers many advantages to data centers and their users, including the following:
		+	*Optimal utilization of computing, storage, and networking resources. Virtualization enables companies or clouds to serve the most users using the least hardware, and with the least unused or idle capacity.
		+	*Rapid deployment of applications and services. SDI automation makes provisioning new infrastructure as easy as making a request via a self-service portal.
		+	*Scalability. Virtualized IT infrastructure is far easier to scale than traditional IT infrastructure. Even companies using on-premises data centers can add capacity on demand by bursting workloads to the cloud when necessary.
		+	*Variety of services and data center solutions. Companies and clouds can offer users a range of ways to consume and deliver IT, all from the same infrastructure. Choices are made based on workload demands and include infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). These services can be offered in a private data center, or as cloud solutions in either a private cloud, public cloud, hybrid cloud, or multi-cloud environment.
		+	*Cloud-native development. Containerization and serverless computing, along with a robust open-source ecosystem, enable and accelerate DevOps cycles and application modernization as well as enable develop-once-deploy-anywhere apps.

-Data Centers have their roots in the huge computer rooms of the 1940s, typified by ENIAC, one of the earliest examples of a data center. Early computer systems, complex to operate and maintain, required a special environment in which to operate. Many cables were necessary to connect all the components, and methods to accommodate and organize these were devised such as standard racks to mount equipment, raised floors, and cable trays (installed overhead or under the elevated floor). A single [[mainframe]] required a great deal of power, and had to be cooled to avoid overheating. Security became important – computers were expensive, and were often used for military purposes. Basic design-guidelines for controlling access to the computer room were therefore devised.

-During the boom of the microcomputer industry, and especially during the 1980s, users started to deploy computers everywhere, in many cases with little or no care about operating requirements. However, as [[IT Operations (Information Technology Operations)|information technology (IT) operations]] started to grow in complexity, organizations grew aware of the need to control IT resources. The advent of Unix from the early 1970s led to the subsequent proliferation of freely available Linux-compatible PC operating-systems during the 1990s. These were called [[Server|"servers"]], as timesharing operating systems like Unix rely heavily on the client-server model to facilitate sharing unique resources between multiple users. The availability of inexpensive networking equipment, coupled with new standards for [[network]] structured cabling, made it possible to use a hierarchical design that put the servers in a specific room inside the company. The use of the term "data center", as applied to specially designed computer rooms, started to gain popular recognition about this time.

-The boom of data centers came during the dot-com bubble of 1997–2000. Companies needed fast Internet connectivity and non-stop operation to deploy systems and to establish a presence on the Internet. Installing such equipment was not viable for many smaller companies. Many companies started building very large facilities, called Internet data centers (IDCs), which provide enhanced capabilities, such as crossover backup: "If a Bell Atlantic line is cut, we can transfer them to ... to minimize the time of outage."
