Cloud-Native systems are complex distributed systems
In the effort to get new digital services to market faster and more efficiently, it can be difficult to anticipate or recreate every possible condition to ensure proper functionality and performance.
Assuring individual service performance is not enough when dealing with distributed systems running at scale. When individual digital services interact with other services in a distributed system, you often get unpredictable and chaotic outcomes related to network reliability, bandwidth, latency, security, admin requirements and more. This can have disastrous effects for users and IT service administrators.
