Data center migration is the center of modern software technology and plays a key role in expanding enterprise capability. The data center concept originated in the late 1950s, when American Airlines and IBM cooperation, to create a company belonging to the United States Sabre reservation system for passengers, so that this part of the main commercial areas become automatic. In 1960, the concept of a data processing system to become a reality, it is used to create and manage aircraft booking system, so that any agency anywhere can timely access to electronic data, then open the door to enterprise class data center.

Since then, physical and technological changes in the field of computing and data storage have taken us to a winding road to today. Let's take a brief look at the history of data centers, from the previous mainframe to the current cloud centric, and their impact on IT decisions.
1946
Electronic digital integrator (ENIAC) was invented in 1946 for the U. S. Army's storage artillery firing code. It was called the first universal electronic digital computer.
1971
Intel adopted its 4004 processor and became the first universal programmable processor in the market. It provides a "block type" service that allows engineers to purchase and customize software, enabling many electronic devices to perform different functions.
1980
The generation of personal computers (PC), which began in the 1981, led to a boom in the micro computer industry.
Sun Microsystems has developed a network file system protocol that allows users of computer clients to access files over the network in a manner similar to accessing local storage.
Computers are quickly installed on any one of us, but little attention has been paid to the environment and operational requirements.
1990s
Early microcomputers began to serve as servers instead of older mainframes, which became increasingly known as data centers. The enterprise starts to organize the platoon server group in the interior.
1990s
Metaphase". The com wave has prompted the company's desire for fast network connectivity and uninterrupted operation. The enterprise starts to construct the server space which can run more equipment (tens of thousands of servers). The data center, as a service model, became popular during this period.
Note: thanks to the PC (server), the IT decision begins in two separate ways. The server allows for application based decisions, while hardware (Data Center) decisions are still within the enterprise scope.
1997
The Apple Corp created a program called Virtual PC and sold it through Connectix. Virtual PC, like SoftPC, allows users to run window copies on a Mac computer to resolve software incompatibility issues.
1999
VMware began selling VMware PC like Virtual Workstation., the original version can only run on Windows systems and later support other operating systems.
Salesforce.com pioneered the concept of delivering enterprise applications through a simple web site.
2001
VMware ESX release, this is a bare metal management procedures, can be run directly on the server hardware, the underlying operating system without additional.
2002
Amazon AWS has begun developing a cloud based service that includes storage, computing, and artificial intelligence implemented through the Amazon Mechanical Turk.
2006
Amazon AWS has begun offering IT infrastructure services to businesses in the form of Web services, and is now commonly referred to as cloud computing".
2007
Sun Microsystems uses modular data centers to change the basic economics of enterprise computing.
2011
Facebook launched the open computing project, which advocates industry wide sharing of technical parameters and practical experience to create the most energy-efficient and economical data center.
2012
Survey shows that 38% of enterprises have been using the cloud, 28% of enterprises plan to start using or expanding cloud.
2013
Telcordia has released General requirements for telecom data center equipment and space. The document provides minimum space and environmental requirements for data center devices and spaces.
Google invested $7 billion 350 million in huge sums of money in 2013 to build its network infrastructure. The cost is for the massive expansion of Google's global data center network, possibly the largest construction effort in the data center industry.
Today and in the future, data centers are shifting from the ownership model of infrastructure, hardware and software to another on-demand subscription and delivery model.
To meet the needs of the application, especially through cloud computing, today's data center capabilities need to match the cloud. With the integration of data centers, cost control and cloud support, the entire data center industry is now changing. Cloud computing matches today's data centers, making IT decisions more flexible access to resources, but the data center itself is a complete and independent entity.
