What Is Live Change?

Live change is only supported by the Huawei Cloud EulerOS 2.0 image. It allows you to upgrade the vCPU or memory specifications of a FlexusX instance without stopping the instance. After the upgrade is complete, you can use the new specifications without interrupting services.

Live change has the following constraints:

  • It is supported only when the FlexusX instance uses the Huawei Cloud EulerOS 2.0 image.
  • The vCPUs and memory can only be upgraded in live change.
  • Live change is supported only between FlexusX specifications.
  • Live change is supported only when both the specifications before and after the change support live change.
  • A maximum of 12 memory live changes can be performed.
  • Live changes cannot be performed in batches.
