- Supports enabling or disabling Hyper-Threading
Note By default, Hyper-Threading is enabled on ECS instances. For more information, see Customize CPU options.
- Provides strong network performance with a large computing capacity
- Supports instance type changes to g6 or c6
- Suitable for the following scenarios:
- Scenarios where large volumes of packets are received and transmitted, such as on-screen video comments and telecom data forwarding
- High-performance databases and in-memory databases
- Data analysis and mining, and distributed memory cache
- Hadoop clusters, Spark clusters, and other memory-intensive enterprise applications
