Top Anti-Patterns to Avoid in Service Architecture
Summary
The article identifies critical anti-patterns in service architecture that can lead to systems becoming slower, harder to operate, less reliable, and more costly than monolithic predecessors. These issues often stem not from single bad decisions, but from the accumulation of individually sound choices, such as clean separations or independent deployments, which collectively result in an unintended, problematic arrangement. A service is defined as a deployable system part controlling its own data, communicating with others over a network. This network communication introduces latency (milliseconds vs. nanoseconds for internal calls) and potential for partial failures, a core problem underlying most anti-patterns. The discussion aims to explain how these anti-patterns occur and how to avoid them, starting with "Splitting Early."
Key takeaway
For AI Architects or Software Engineers designing new microservice systems, recognize that architectural problems often arise from the cumulative effect of individually reasonable choices, not single errors. Avoid "splitting early" by carefully evaluating the long-term implications of each service boundary decision. Prioritize robust communication patterns and data ownership to prevent common anti-patterns that degrade system performance and reliability.
Key insights
Seemingly good architectural decisions can accumulate into problematic service architectures.
Principles
- A service is self-deployable and data-controlling.
- Services communicate over a network.
- Network calls introduce latency and failure modes.
