Do I Need to Reconstruct the Legacy System If I Want to Use IEC? How Can I Do That?

It depends on your environment and requirements. Before you start, consult the Huawei Cloud professional team.

Consider the following aspects when you determine whether to reconstruct your system:

• Workload migration

  The migration policy is as follows: Migrate workloads that are sensitive to network latency or need to be quickly deployed in batches nearby to IEC. Migrate workloads that often generate a large amount of data and need to run stably for a long time to the central cloud, or retain them on the central cloud if you have migrated them to the cloud.

• Consistent experience

  IEC uses the same architecture as the central cloud and ensures consistent experience in using basic resources such as compute, storage, and network resources. You only need to check the instance specifications supported by IEC. If you want more custom specifications, contact customer service to apply.

• Data processing and communication methods

  Consider data processing and communication method changes that might be caused by workload migrations.
