A burstable instance is a VM instance that provides a baseline level of CPU performance that can automatically burst to a higher level to support occasional spikes in usage, for a limited amount of time.
Burstable instances are well suited for scenarios where an instance is typically idle, or has low CPU utilization with occasional spikes in usage. These instances are also ideal for scaled-down workloads that do not require a full core. For example, microservices, low-latency interactive applications, small and medium databases, virtual desktops, development, build, and stage environments.
