Millions of lines of code comprise these apps, and they include hundreds of interconnected digital services and open-source solutions , and run in containerized environments hosted across multiple cloud services. This may result in unnecessary troubleshooting exercises and finger-pointing, not to mention wasted time and money.

Instead, focus on understanding what the workloads exercise to help us determine how to best use them to aid our performance assessment. sysbench is a widely used open-source benchmarking tool that is designed to evaluate the performance of CPU, memory, disk I/O, and database systems. Instead, use the default settings.

There are many possible failure modes, and each exercises a different aspect of resilience. Another problem is that a design control, intended to mitigate a failure mode, may not work as intended. STPA is based on a functional control diagram of the system, and the safety constraints and requirements for each component in the design.

Service-oriented architecture (SOA) was hyped in the mid-2000s as a modern take on distributed systems architecture, which through modular design would provide productivity through loose coupling between collaborative services—so-called "WebServices"—communicating through externally published APIs. Most well-known is probably Apache Camel.

While open source Redis comes with primitives to help reshard a cluster, they are inadequate. With online cluster resizing, our goal was to design a fully managed experience for cluster resharding, which would support both scale-out and scale-in and retain open source compatibility.
