General Computing-Basic ECSs

General computing-basic ECSs are suitable for scenarios that require moderate CPU performance generally but burstable high performance occasionally while keeping costs low. The performance of such ECSs is constrained by the baseline performance and CPU credits. CPU credits do not incur additional costs. For details, see CPU Credits.
