ECS Advantages

ECS supports automated scaling of compute resources based on traffic changes and predefined scaling policies. You can customize ECS specifications including vCPUs, memory, and bandwidth to let your applications run in a flexible, efficient environment.

Reliability

  • A broad range of EVS disk types

    EVS disk types are classified based on I/O performance. Select EVS disks based on service requirements.

    For more information about EVS disk specifications and performance, see Elastic Volume Service User Guide.

  • Distributed architecture

    ECS provides scalable, reliable, and high-throughput virtual block storage on a distributed architecture. This ensures that data can be rapidly migrated and restored if any data replica is unavailable, preventing data loss caused by a single hardware fault.

  • Backup and restoration

    You can set automatic backup policies to back up in-service ECSs and EVS disks. You can also configure policies on the management console or use an API to back up the data of ECSs and EVS disks at a specified time.

Security

  • Multi-dimensional protection

    A number of security services, such as Web Application Firewall (WAF) and Vulnerability Scan Service (VSS) are available.

  • Security evaluation

    Cloud security evaluation and security configuration check help you identify security vulnerabilities and threats, reducing or eliminating your loss from viruses or attacks.

  • Intelligent process management

    You can customize an allowlist to automatically prohibit the execution of unauthorized programs.

  • Vulnerability scan

    Comprehensive scan services are available, including general web vulnerability scan, third-party application vulnerability scan, port detection, and fingerprint identification.

Hardware and Software

  • Professional hardware devices

    You can deploy ECSs on professional hardware devices that allow in-depth virtualization optimization, delivering superior virtual server performance.

  • Virtual resources accessible anytime, anywhere

    You can obtain scalable, dedicated resources from the virtual resource pool anytime, anywhere, so your applications can run in reliable, secure, flexible, and efficient environments. You can use your ECS like the way you are using your local computer.

Scalability

  • Automated scaling of computing resources

    Dynamic scaling: AS automatically increases or decreases the number of ECSs in an AS group based on monitored data.

    Periodic/Scheduled scaling: AS increases or decreases the number of ECSs in an AS group at a regular interval or a specified time based on the predicted load or a pre-set plan.

  • Flexible adjustment of ECS specifications

    ECS specifications and bandwidth can be flexibly adjusted based on service requirements.
