Burstable instances are the only instances that use CPU credits for maximum cost efficiency. This topic describes the benefits of burstable instances.
Lower costs
The cost of a burstable instance is 10% to 48% lower than that of a shared instance that has the same configurations.
The actual performance of a burstable instance depends on the accumulation and usage of CPU credits. Before you purchase a burstable instance, familiarize yourself with the relevant terms such as baseline performance and CPU credits of burstable instances. For more information, see Overview.
Finer-granularity specifications
ecs.t5-lc2m1.nano is the lowest-specification instance type of burstable instances, which has one vCPU and 0.5 GiB of memory. Burstable instances allow you to flexibly combine instance types to meet finer-granularity requirements. For more information, see the "t5, burstable instance family" section of the Overview topic.
Predictable performance
Burstable instances provide a baseline level of CPU performance. You can predict the burstable performance of burstable instances based on their baseline performance and accrued CPU credits to 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.
