Question
His company has deployed a small system in the offline IDC computer room, and recently needs to migrate to the Huawei Cloud environment. When the business was deployed, resources were limited and the operation and maintenance personnel were familiar with the deployment architecture. The operation and maintenance personnel used 5 physical hosts to complete the service deployment. In order to improve the utilization rate of the host during business deployment, multiple modules are deployed in each physical host, and web and message middleware, applications and databases are deployed on the same host. When migrating business to the cloud, which of the following methods is the best choice for operation and maintenance personnel?
Options
- ASort out the open ports of the offline business system, set up an appropriate security group
- BTake advantage of the characteristics of diverse services and flexible resources on the cloud,
- CAfter the business is migrated to the cloud, in order to facilitate maintenance, the operation and
- DBased on the perspective of convenient architecture and maintenance, directly follow the offline

Explanation
Option B is correct because migrating to the cloud is the ideal opportunity to redesign a resource-constrained architecture. The original deployment packed web servers, message middleware, applications, and databases onto the same physical hosts only because resources were limited - not because it was good design. Cloud platforms like Huawei Cloud offer flexible, scalable resources that allow each component to be separated into its own appropriate service, improving security, performance, and maintainability.
Option A is wrong because setting up security groups is only one small step in a migration, not a migration strategy - and security groups designed around a poorly architected system will inherit that system's weaknesses. Option C is wrong because maintaining the same co-deployed architecture after migration defeats the purpose of moving to the cloud; convenience in the short term sacrifices all the scalability and isolation benefits the cloud provides. Option D is wrong for the same core reason: directly replicating the offline architecture (a "lift and shift" of a compromised design) means carrying technical debt and resource-sharing problems into the new environment rather than fixing them.
Memory tip: The original architecture was bad by necessity, not by choice. Cloud migration removes that necessity, so the correct answer always involves redesigning properly rather than copying the old constraints into the new environment.
