In the past few days, the company is preparing to migrate the application database and add some servers, so after understanding the virtualization of VMware, the following content is found on the Internet, and I think it is very good and I turned it down!
When the owner went to a company and saw a book introducing VMWare ESXi, I flipped it through. I also set up VMWare ESXi 4.0 in the company before. This time it is to understand some theoretical knowledge. Later, when talking with their engineers, he talked about the version of VMWare Enterprise Edition. He said that VMWare ESX is a free version. I dare not agree with this. I think he may be looking for a cracked version! Still understand the difference between VMWare EXSi and EXS!
Both VMware ESX and VMware ESXi are bare metal hypervisors installed directly on the server hardware. Both have industry-leading performance and scalability. The difference is that VMware ESXi uses a unique architecture and operations management method. Although neither depends on the operating system for resource management, VMware ESX relies on the Linux operating system (called the service console) to perform two management functions: execute a script, and install a third-party program for hardware monitoring, backup, or system management. Tripartite agent. The service console has been deleted in ESXi, which greatly reduces the space occupied by this management program and realizes the development trend of migrating management functions from the local command line interface to remote management tools. A smaller ESXi code base means that the "attack surface" is smaller and less code needs to be patched to improve reliability and security. The function of the service console is replaced by a remote command line interface that conforms to system management standards.
VMware ESXi is the easiest way to get started with virtualization. By consolidating applications on fewer servers, you can reduce hardware, power, cooling, and management costs, thereby starting to save money. VMware ESXi has been optimized and tested, and it can even run the most resource-intensive applications and databases with the lowest performance overhead. Use VMware ESXi, you can run on a single server
multiple operating systems
, thus
reducing hardware costs
run more environmentally friendly data center, thereby
reducing energy costs
make application
backup and recovery simpler
, running in a production environment
Resources The most occupied application
.
According to VMWare engineers, VMWare ESX is used more in the production environment, VMWare ESXi is used less in the production environment, EXSi is smaller, and it can even be used in a U disk. The latest version of VMWare supports vlan technology, different operating systems in the virtual machine can be in different vlan, this function is very good!
VMWare ESXi can be obtained from VMWare's official website for free. VMWare ESX, vSphare, vCenter and some kits are very expensive!
