This article explains how to design and implement custom routing strategies—including default branch routing, version‑specific routing, and service‑specific routing—to achieve isolated version testing and gray‑release deployments in distributed microservice systems.
This article explains how to design custom routing rules, version‑based load balancing, and gray‑deployment strategies in distributed microservice systems to isolate service versions, ensure safe acceptance testing, and smoothly roll out new releases.
This article explains how to design custom routing strategies for versioned microservices, including default master branch routing, unified version routing, and service‑specific routing, and shows how to apply these rules to achieve gray deployments with load‑balancing and seamless version isolation.
This article presents a detailed overview of change management practices, covering compatibility design across hardware, base software, and applications, release strategies, gray‑deployment techniques, data migration analysis, rollback planning, configuration change control, and verification procedures to ensure system stability and reliability.
This article outlines a comprehensive, data‑driven methodology for reducing MySQL storage expenses—including background analysis, challenge identification, a nine‑grid systematic framework, benefit estimation, safety and stability verification, gray‑scale rollout, and rollback strategies—demonstrating over 50% disk space savings in a large‑scale billing system.
The article details Meituan's large‑scale RASP (Runtime Application Self‑Protection) rollout, covering deployment challenges such as heterogeneous Java environments, performance impact of agent injection, upgrade difficulties, monitoring complexities, and the engineering solutions—including agentmain/premain hybrid loading, gray‑scale upgrades, hot‑update plugin architecture, and performance optimizations—validated with concrete metrics and benchmarks.
This article outlines the background, challenges, systematic methods, benefit calculations, data‑safety and stability checks, verification steps, rollback strategies, and gray‑deployment practices for lowering MySQL storage expenses in large‑scale billing systems while maintaining system reliability.
The LUBAN MQ platform introduces a gray‑deployment extension for RocketMQ that isolates gray traffic by assigning configurable gray queues, adds a graySubscriptionTable and grayFlag in broker and Namesrv, uses shared consumer groups with a custom rebalance strategy, and ensures loss‑less offset merging and seamless switch‑over.
This article explains Knative’s traffic‑driven autoscaling and gray‑release capabilities, detailing the request flow architecture, the roles of Service, Configuration, Route and Revision, and walks through built‑in scaling strategies such as KPA, HPA, scheduled‑HPA, event‑gateway and custom plugins, with practical examples.
