The complexity of modern business systems means that the migration of an application to the cloud causes a risk of performance and reliability (P&R) problems. Cloud project managers need to consider the P&R risks so applications continue to deliver satisfactory performance during and after migration.
- Cloud experts use the term performance when they mean load vs. capacity and this is leading to an assumption that current plans adequately deal with performance.
- Although Application Dependency Mapping identifies the major network flows in a system, it does not characterise those flows in terms of sensitivity to network latency.
- Application performance and reliability is key to a user’s assessment of the success of a cloud migration project.
