Burstable instances are the only instances that use CPU credits for maximum cost efficiency. This topic describes the benefits of burstable instances.
ecs.t5-lc2m1.nano is an instance type of burstable instances, which has the baseline level specifications of one vCPU and 0.5 GiB memory. The instance specifications of burstable instances allow you to flexibly combine instance types to meet finer-granularity requirements. For more information, see t5, burstable instance family.
Predictable CPU performance
Burstable instances provide a baseline level of CPU performance (baseline performance). You can predict the burstable performance of a burstable instance based on its baseline performance and accrued CPU credits, and select appropriate compute capabilities.
Higher network performance
Burstable instances use the most advanced network-based technologies to reduce network latency to one-third of that of the last-generation instances.
