Production Development with Microservices Architecture and DevOps Practices

Microservice systems require reliable delivery, stable runtime environments, and production controls to achieve both high throughput and operational stability. This paper proposes a production-development framework that combines (i) runtime and toolchain version pinning, (ii) progressive delivery (canary / blue-green) with automated rollback, (iii) SLO and error-budget-based reliability management, and (iv) supply-chain security controls for build and artifact integrity. The framework is assessed via an 8-week synthetic observation design that mirrors operating conditions typical for mid-size telecom/fintech organizations (Central Asia), using eight independently deployable services. The evaluation is reported through DORA-style delivery metrics (deployment frequency, lead time, change failure rate, MTTR) and SLO attainment, and includes an ablation that isolates the expected contribution of each practice. The results indicate that deterministic builds (pinning) and progressive delivery provide the strongest improvements in delivery stability, while SLO/error-budget policies reduce incident impact by enforcing clear rollback and release-freeze rules.
