What potential issue should be considered when migrating an on-premises database to the public cloud?

When migrating an on-premises database to the public cloud, a significant potential issue to consider is the format of the workload. This encompasses how the applications and databases are designed to operate, including their performance characteristics, dependencies, and configurations. Public clouds may have different resource management, scaling capabilities, and latency characteristics compared to traditional on-premises environments.

The format of the workload can affect how efficiently the database performs in the cloud environment. An application optimized for local infrastructure may not leverage the cloud's capabilities, such as auto-scaling, network latency considerations, or different data management practices effectively. Additionally, various cloud service models (like IaaS, PaaS, SaaS) may imply shifts in workload handling that require adjustments in how data is processed, accessed, and stored.

Understanding these implications allows for adequate planning and adaptation of the database and its associated applications, ensuring that they can function properly and meet performance requirements in the public cloud setting. This focus on workload format can lead to successful migrations that fully leverage cloud advantages, such as elasticity and managed services.
