Microservices: The Emerging Complexity Driven by Trends and Alternatives to Over‑Design

The adoption of microservice‑based architectures has grown exponentially over the past decade, often driven more by industry trends than by a careful evaluation of system requirements. This phenomenon has generated unnecessarily complex implementations—like using a bazooka to kill an ant. Distributed architectures without solid foundations in domain capabilities, workloads, operational independence, or real scalability needs have become a common pattern in the software industry. In many cases, organizations migrate without having a mature discipline in observability, traceability, automation, domain‑driven design, or an operational model capable of supporting highly distributed systems; as a consequence, they end up with distributed monoliths that require coordinated deployments and suffer cascading failures, losing the benefits originally promised by microservices (Iyer, 2025; Fröller, 2025).

Over‑Design

The primary issue in microservices is not rooted in their architectural essence, but in the over‑design that emerges when attempting to implement such architecture without having ...
