Assurance

In the assurance phase of cloud migration, you need to perform the following tasks to ensure a smooth transition to the new cloud environment:

• Cloud platform monitoring: Establish an effective monitoring system to monitor the performance, availability, and security of the cloud platform. Set an alarm mechanism to detect and resolve potential problems in a timely manner.
• System monitoring and O&M: Set system monitoring and alarms to detect and resolve potential problems in a timely manner. Deploy infrastructure monitoring tools to monitor key indicators of servers, storage devices, and networks, and ensure that the log recording and error alarm mechanisms work properly.
• Security check and bug fixing: Check for potential vulnerabilities or weaknesses and take appropriate remedial measures to enhance security. Update and patch the system and software to ensure that the components and versions in use are up-to-date and that security patches are applied in a timely manner.
• Backup and DR policies: Evaluate and set new backup and DR policies to ensure data security and recoverability. Perform regular backup and DR drills to verify backup availability and recovery procedures.
• Optimization and adjustment: Optimize and adjust the system and applications based on the running status. Identify bottlenecks and performance problems by monitoring performance indicators, and adjust and optimize the system accordingly to improve system stability and responsiveness.
• Training and support: Provide necessary training and support for the O&M team to ensure that they are familiar with the new cloud environment and tools.
• Document output: Record and maintain the documents for future reference and archiving.
