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.
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.
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 a data replica is unavailable, preventing data loss caused by a single hardware fault.
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.
A number of security services, such as Web Application Firewall (WAF) and Vulnerability Scan Service (VSS) are available.
Cloud security evaluation and security configuration check help you identify security vulnerabilities and threats, reducing or eliminating your loss from viruses or attacks.
You can customize an allowlist to automatically prohibit the execution of unauthorized programs.
Comprehensive scan services are available, including general web vulnerability scan, third-party application vulnerability scan, port detection, and fingerprint identification.
You can deploy ECSs on professional hardware devices that allow in-depth virtualization optimization, delivering superior virtual server performance.
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.
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.
ECS specifications and bandwidth can be flexibly adjusted based on service requirements.
