Introduction

ECS (Elastic Compute Service) cloud server is a computing service based on virtualization technology provided by Alibaba Cloud. It aims to provide secure, reliable, highly elastic, and scalable cloud computing infrastructure. With high performance, high availability, elastic scaling, and support for multiple operating systems and applications, ECS cloud server can be easily created or managed through the Alibaba Cloud console.

ECS cloud servers are a type of computing resource service that provides complete CPU, memory, and network resources. Users can easily adjust resource capacity according to actual business needs to meet the running requirements of different applications. ECS cloud servers support both pay-as-you-go and subscription-based billing methods to meet different user cost needs.

Features

As a cloud computing infrastructure service, ECS cloud servers have the following features:

1. Multiple instance types: ECS cloud servers provide multiple instance types, including general-purpose, compute-optimized, memory-optimized, and shared instance types.

2. Multiple operating systems: ECS cloud servers support multiple operating systems, including Windows, Linux, FreeBSD, etc.

3. Multiple network types: ECS cloud servers support multiple network types, including classic network and VPC (Virtual Private Cloud) network.

4. Elastic scaling: ECS cloud servers provide elastic scaling, which supports automatic or manual scaling according to actual business needs.

5. Automatic snapshot backup: ECS cloud servers provide automatic snapshot backup, which can automatically back up cloud server data according to user-set policies.

6. Security and reliability: ECS cloud servers support various security measures, including security groups, network ACL (Access Control List), etc. At the same time, ECS cloud servers adopt Alibaba Cloud’s self-developed cloud computing architecture, which has high availability and fault tolerance.
