15 Questions
What is the primary challenge of full-stack workload profiling in the cloud era?
Too many layers and abstractions
True or false: CPU profiling is necessary to understand the effects of an issue on the system.
True
True or false: User-level profiling at the application layers is a form of observability.
True
What is needed to improve performance analysis in the cloud?
A disciplined performance methodology
True or false: Traditional mechanisms such as system characterization and application profiling are enough to determine the root cause of an issue.
False
What is important to understand the effects of an issue on the system?
CPU profiling
True or false: To improve performance analysis in the cloud, more tools for tracing and instrumentation at the application level are needed.
True
What can be helpful in identifying low-hanging fruit?
Traditional mechanisms
True or false: The many layers and abstractions in cloud computing make full-stack workload profiling easier than before.
False
What is needed to determine the root cause of an issue?
System characterization and application profiling
What kind of tools are used for tracing and instrumentation at the application level?
User-level profiling
What can be helpful in understanding what the application is doing at the platform level?
System characterization and application profiling
What is more difficult than it was before the advent of the cloud era?
Full-stack workload profiling
What can be difficult to bridge?
The gap between the hardware and software
What exists in each domain to help with observability?
User-level profiling
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.
