What are the characteristics of CVM ecs? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

CVM ecs runs as a virtual machine, and the host resources include basic computing components such as CPU, memory, disk and so on. Users can deploy and activate quickly according to their business needs. According to the specific situation of application access, users can dynamically adjust the host-related resources and bandwidth resources online in a few minutes.

Elastic adjustment

Configuration changes can be made to a single server. After purchasing a CVM, you can freely change your configuration according to the growth or reduction of business, and all operations will be completed in a few minutes. For the peak period of e-commerce, games and other business, flexible ways can be used to help the business through such peak. After the peak of the business, the excess resources can be released to reduce the expenses of the business.

Flexible automation

Users can purchase various components of cloud computing resources separately, or adjust the combination at any time according to the business situation, and freely bind and unbind each cloud resource. Many service providers also provide comprehensive API to facilitate users to build automatic operation and maintenance management platform, which can be integrated with existing resources to the maximum extent and improve efficiency.

Stable and reliable

General service providers will guarantee 99.95% service availability and data reliability of not less than 99.9999%. The cloud disk of the CVM is protected by multiple copies, and the local disk is protected by RAID array to prevent data loss. At the same time, the cloud platform supports hot migration. If there is a failure or problem of the host, you can quickly migrate the CVM on the host to avoid affecting the use of users.

High performance of operation

For example, the performance metrics of CPU and memory of CVM are industry-leading, as well as local SSD disk CVM, which provides ultra-high IOPS performance. Excellent network processing capacity to meet a variety of business application requirements.

Safety guarantee

Through the mutual isolation of CPU, IO and network among users and 100% complete network isolation between users, CVM leasing can effectively prevent performance interference caused by resource encroachment among users, and achieve fault and security isolation. At the same time, it supports the login mode of SSH (Linux system) and provides network firewall function to protect the safe use of users.
