As we all know, cloud computing architecture has the feature of elastic expansion, and virtual machine is a product under cloud computing architecture. Elasticity can be understood as that users can flexibly purchase resources according to actual business needs. Elastic virtual machine is a virtual machine that supports users to freely schedule computing resources and runs in a cloud computing environment without being limited by traditional hardware devices. The use of elastic virtual machine can effectively avoid the waste of enterprise resources. What are the "elasticity" of elastic virtual machines? Today, Micron Network will take you to understand the "elasticity" of elastic ECS.

1、 Billing flexibility
1. Controllable cost
From the perspective of host cost, because services can be distributed to multiple servers, resources are fully utilized, and hardware, power and maintenance costs are reduced. The billing of virtual machine is based on the usage, that is, the customer can control the use cost according to the usage.
2. Purchase on demand
At present, there are a variety of standard specifications of virtual machines for customers to choose from and support a variety of mainstream operating systems. In addition, virtual machines do not need to bind network bandwidth and IP geology. While meeting customers' various application needs, customers can also more flexibly customize the specifications of virtual machines to help customers use and purchase on demand, It can minimize the cost of customer deployment and operation and maintenance.
2、 Resource call elasticity
Compared with conventional servers, it is difficult for users to make configuration changes to a single server. The basic feature of elastic virtual machine is distributed architecture. The advantage of the decentralized architecture is that it can meet customers' business growth and emergency needs. Customers can flexibly expand the memory, system disk and bandwidth of the virtual machine online at any time, which has reached the goal of improving the overall capacity of the extended service. This is not possible with traditional servers.
3、 Business management flexibility
Elastic virtual machine deployment is fast and simple. It only takes a few minutes for an elastic virtual machine to be created and started. Customers can even create one or more virtual machines at the same time, which can be completed in the same few minutes. Customers can have the super administrator rights of the virtual machine owner. The elastic virtual machine is deployed quickly, which can be bought and used immediately, meeting the sudden needs of customers.

The above is the "elasticity" of the elastic cloud server shared by Micronet. Huawei Cloud, a micro network agent, is an excellent cloud computing service provider with perfect industry solutions and excellent cloud computing technology. The self-developed pure SSD architecture ECS breaks the industry record with 50000 IOPS random read/write speed and 800 Mb/s throughput as performance indicators. The ECS elastic cloud server uses hardware devices with a pure SSD architecture. In just a few minutes, you can easily obtain and enable the cloud to meet your computing needs. Expanding the flexibility of resource use also saves you computing costs, simplifies IT operations, and enables you to pay more attention to core business innovation.
