Microservices Everywhere
Independent deployability as religion. Correct for some; ruinous cargo-cult for most.
Microservices failed as a default because network boundaries multiply failure modes faster than team autonomy. Netflix needed it; your CRUD shop needed a modular monolith and sleep. The fad cost was paying senior distributed systems salaries to ship slower.
Cost of the fad
Teams split 4-person products into 40 services, then hired SREs to babysit the mesh. Many later consolidated — after years of distributed tracing invoices and on-call trauma. See case studies on premature microservices and big-bang cutovers for named failure modes.
Case studies
- Big-bang microservices cutover weekend — Weekend cutover rollback; months of dual-run and incident debt
- Mid-market CRUD shop splits into forty repos — 3× infra spend; velocity flat for two years
- AI codebase rewrite pilots that shipped nothing — Six-figure LLM API and SI costs; production cutover: zero
Patterns
Context
Split everything, then pay for the glue
Hyperscale patterns escaped the companies that needed them. Containers unified packaging; Kubernetes became the cloud OS; microservices and NoSQL were sold as defaults. Mobile-first stuck because screens changed. Cargo-cult distributed systems stuck around as invoices. The durable move was packaging and ops maturity — not rewriting every app into a mesh.

Enterprise SOA
Reuse via shared services — in theory. In practice: central buses and political ownership fights.
$ ESBs, governance boards, and "service portfolios" burned seven-figure programs. Many orgs got distributed monoliths with worse latency and a permanent integration team.

Kubernetes
Container orchestration that became the cloud's OS. Overkill for many; unavoidable for many others.

Modular monolith
One deployable with clear boundaries. The unfashionable default that keeps shipping while microservices argue about ownership.

Service mesh everywhere
Sidecar proxies for every microservice. Netflix problems with startup headcount.
$ Istio sidecars on three-service startups burned SRE headcount on mTLS ceremonies nobody could debug. Many teams ripped mesh out before the observability dashboard paid rent.
