About this ebook

Historically, companies have employed systems administrators to run complex computing systems. This systems administrator, or sysadmin, approach involves assembling existing soft‐ ware components and deploying them to work together to produce a service. Sysadmins are then tasked with running the service and responding to events and updates as they occur. As the system grows in complexity and traffic volume, generating a corresponding increase in events and updates, the sysadmin team grows to absorb the additional work. Because the sysadmin role requires a markedly different skill set than that required of a product’s developers, developers and sysadmins are divided into discrete teams: “development” and “operations” or “ops.” The sysadmin model of service management has several advantages. For companies deciding how to run and staff a service, this approach is relatively easy to implement: as a familiar industry paradigm, there are many examples from which to learn and emulate. A relevant talent pool is already widely available. An array of existing tools, software components (off the shelf or otherwise), and integration companies are available to help run those assembled systems, so a novice sysadmin team doesn’t have to reinvent the wheel and design a system from scratch. The sysadmin approach and the accompanying development/ops split has a number of disadvantages and pitfalls. These fall broadly into two categories: direct costs and indirect costs. Direct costs are neither subtle nor ambiguous. Running a service with a team that relies on manual intervention for both change management and event handling becomes expensive as the service and/or traffic to the service grows, because the size of the team necessarily scales with the load generated by the system.
