Scenarios
Users have their own on-premises IDCs, but as time goes on, the server cluster in the server room has been running for 8-10 years and the equipment gradually reaches the service life. In this case, most enterprises will choose to remove the equipment that has reached their service life from the network. In addition, as the equipment is removed from the network, original business systems, application clusters, databases, and object storage services need to be migrated to the cloud.
Pain Points
Removing equipment from the network and migrating services to the cloud usually face the following challenges:
· Interruption and shutdown not allowed: The business system has high requirements for interruption and downtime and cannot be shut down for an extended period of time. Otherwise, business continuity is affected.
· A large amount of data: With the development of businesses, the amount of data increases gradually, and a large amount of data to migrate may slow down the migration process.
· Complex business association: The association between multiple business systems and application clusters makes migration difficult.
· Lack of system maintenance personnel: An enterprise may lack system maintenance personnel due to various reasons.
· High difficulty in redeployment after application iterations: The difficulty of redeployment and configuration of an application system increases after multiple iterations.
Product Advantages
· Minimum downtime: CMS can provide a migration service solution with minimum downtime for the government and enterprises to ensure the shortest interruption time during the migration of business systems.
· Impactless migration: CMS will not affect existing business systems during the migration, ensuring business continuity.
· Budget information: Before the migration, CMS can roughly provide the required cloud resources and budget information, so that users can configure resources and plan the budget easily.
· Data verification: After the migration, CMS will verify system information and data, and generate inspection reports to ensure the accuracy and consistency of data migration.
Scenario Architecture
Product Combinations
In this scenario, you can use the service in combination with the following products:
· Elastic Cloud Server (ECS): Bears business systems and application clusters after migration.
· EIP: Provides static EIP for servers after migration to guarantee accessibility to public networks.
· Object-oriented storage (OOS): Stores object data after migration to meet persistent storage requirements.
