Why moving AS400 setup to the cloud is a no-brainer

If you got mission-critical workloads on AS400 applications, migrating the entire AS400 portfolio to the cloud is the need of the hour to attain higher scalability, agility, and cost benefits.

• Agility: IT resources on demand, zero dependencies on hardware.
• Scalability: Pay only for what’s needed, accommodate unforeseen surges and seasonal usage patterns.
• Low maintenance overheads: Owing to a diminishing workforce, daily system maintenance adds substantially to the overheads. But system maintenance in cloud hosting is 30%-70% less expensive than the on-premises option.
• Security: Built-in application security measures with a multifaceted approach; role-based authentication.
• Architecture flexibility: As workloads are independent of hardware resources on the cloud, it’s easy to make the system future-ready to better match changing business needs and handle unexpected demand levels.

AS400 Cloud Migration Pre-requisites

• A complete understanding and documentation of the AS400 infrastructure, including all existing workflows.
• Risk assessment, budgeting, and security analysis to host the workloads on the cloud.
• Key stakeholders must be informed about the order of migration and its impact on business.
• Check if the existing versions of RPG & OS400 need remediation.

Common challenges during such AS400 lift and shift process

• Architectural complexity: The cloud architecture must be compatible with the in-house IT infrastructure to minimize inconsistencies and interoperability problems.
• Application dependencies: No complete clarity on the relationship between the application and the servers, databases, and other services to which it connects.
• Maintain system performance: It’s critical to ensure that the network provider offers optimization services to minimize all latencies.
• Security considerations: To avoid security risks while moving data to the cloud infrastructure, the migration plan must include the tools, practices, and policies to comply with relevant security requirements.
• Old databases: The aged AS400 database can have challenging relational structures. To migrate it and its contents, restructuring the database to map the new data model is important.
• No data recovery plan: Understanding data risks and having a data recovery plan is critical. Cloud environments do support disaster recovery (DR) but a lack of cloud experience can make the execution challenging.
• Knowledge of configuration: The people managing the systems might have already retired; when nobody knows how the old system is configured, you are one step behind.
• Change management: The need to plan KT sessions and allocate training resources to ensure all departments are equitably prepared for the transition.
