Technology Lifecycle Management

This thread tracks the evolution of Slack's approach to managing the lifecycle of its internal infrastructure projects, from development and support to eventual retirement. Initial posts detail the challenges of managing a broad remit of infrastructure services, leading to duplicated effort and difficulty in retiring older technologies. This post introduces a six-stage lifecycle model (Alpha, Beta, Active, Maintenance, Deprecated, Retired) designed to standardize technology status, improve communication with engineering peers about support levels and future expectations, and provide a framework for controlled migration and retirement of technologies. The case study highlights how this framework facilitated the migration through three successive internal compute platform offerings (BuiltBySlack, Kubernetes-based platform, and a subsequent iteration), improving resource allocation and customer communication.
