VMware
VMware is a global leader in desktop to data center virtualization solutions. Customers of all sizes around the world rely on VMware to reduce costs and operating expenses, ensure business continuity, strengthen security and go green. In 2007, VMware's annual revenue reached US$1.3 billion, with more than 100,000 users and more than 10,000 partners, making it one of the fastest-growing listed software companies. VMware is headquartered in Palo Alto, California.
Virtualization is an abstraction layer that separates physical hardware from the operating system, providing greater IT resource utilization and flexibility.
Virtualization allows multiple virtual machines with different operating systems to run independently and in parallel on the same physical machine. Each virtual machine has its own set of virtual hardware (such as RAM, CPU, network card, etc.) into which operating systems and applications can be loaded. Regardless of the actual physical hardware components, the operating system treats them as a consistent, standardized set of hardware.
"In the next few years, virtual machines will no longer be limited to simple resource deployment and use as computer rooms, they will provide a basic building block to improve desktop mobility, security stability and availability."
—Mendel Rosenblum, Chief Scientist, VMware Inc. Virtual machines are encapsulated in files so they can be quickly saved, copied, and deployed. An entire system (fully configured applications, operating system, BIOS and virtual hardware) can be moved from one physical server to another in seconds for zero-downtime maintenance and continuous workload consolidation.
The concept of virtualization first emerged in the 1960s as a way to partition mainframe hardware, which was a scarce and expensive resource. Over time, microcomputers and PCs provided more efficient and economical ways to allocate processing power. Therefore, by the 1980s, virtual technology was no longer widely used.
In the 1990s, researchers began to explore how to use virtualization to solve some of the problems associated with the proliferation of cheap hardware, such as underutilization, rising management costs, and vulnerability to attacks.
Now, virtualization technology is at the forefront of the times and can help enterprises upgrade, manage and secure their IT infrastructure around the world.

The benefits of Jiangnan Bank Data Center are good. According to the relevant information, the salary of Jiangnan Bank data center is 4,000 to 6,000 yuan, six insurances and one fund, no overtime, working hours 9:00-17:00, weekends off, paid annual leave, training, Jiangnan Bank data The center pays well.

The difference is as follows:
i (internet) d (data) c (center): a data center that provides Internet services, usually in the form of third-party hosting, new The technology has a high degree of application and a large number of platform cloud application clouds are deployed; it is based on the INTERNET network and provides an operation and maintenance facility base and related services for equipment that centrally collects, stores, processes and sends data. The main services provided by IDC include hosting (leasing of computer seats, racks, VIP computer rooms), resource leasing (such as virtual hosting business, data storage services), system maintenance (system configuration, data backup, troubleshooting services), management services ( Such as bandwidth management, traffic analysis, load balancing, intrusion detection, system vulnerability diagnosis), and other support and operation services.
The FDC data center is located in the Chicago computer room in Illinois and the Denver computer room in Colorado. It is a typical unlimited traffic computer room and the largest unlimited traffic computer room in the world. 40G bandwidth goes directly to the backbone of the United States, and BGP4 is used to construct network connections, which is stable and fast. Multi-line integration ensures unobstructed lines and 24/7 real-time monitoring and uninterrupted service. Therefore, the group it targets is also a group with relatively large demand for traffic. Redundant systems are in place. Multi-gigabit lines, closed-circuit monitoring equipment, ultra-large traffic, the same computer room as Time Warner AOL, extremely cost-effective. The famous American Unlimited Traffic King server is located in this computer room. It is a professional service for customers in many countries around the world who need high-traffic American servers. Select the computer room.
