As a basis for that discussion, first some definitions: Dependability The degree to which a product or service can be relied upon. This means a system that is not merely available but is also engineered with extensive redundant measures to continue to work as its users expect. Availability and Reliability are forms of dependability.

Due to its popularity, the number of workflows managed by the system has grown exponentially. The scheduler on-call has to closely monitor the system during non-business hours. As the usage increased, we had to vertically scale the system to keep up and were approaching AWS instance type limits.

We recently extended the pre-shipped code-level API definitions to group logical parts of our code so they’re consistently highlighted in all code-level views. Another benefit of defining custom APIs is that the memory allocation and surviving object metrics are split by each custom API definition.

The quality can be subjective, so different teams may use different definitions based on the context. Keeping good code quality is also crucial for developing safety-critical systems. Code can be considered good quality if it is clear, simple, well tested, bug-free, refactored, documented, and performant.
