Study Notes
- Full-stack workload profiling is more difficult than it was before the advent of the cloud era because of the many layers and abstractions in cloud computing.
- Observability solutions exist in each domain, including user-level profiling at the application layers, high-level observability for monitoring and logging at the orchestration layers, and many tools for tracing and instrumentation at the application level.
- CPU profiling is important to understand the effects of an issue on the system.
- A disciplined performance methodology is needed in the cloud because the different layers between the hardware and software can be difficult to bridge.
- Traditional mechanisms such as system characterization and application profiling can be helpful in identifying low-hanging fruit, but more is needed to determine the root cause of an issue.
- System characterization and application profiling can be helpful in understanding what the application is doing at the platform level, but more is needed to determine the root cause of an issue.
- Bridging the gap between the cloud layers is difficult, and traditional mechanisms are not enough to determine the root cause of an issue.
- To improve performance analysis in the cloud, a disciplined performance methodology is needed.
