IT Operating Environments Best Practices

Overview

Environments created without a formal process accumulate the governance deficits that informal creation produces: no documented purpose that justifies their existence, no named owner accountable for their governance, no defined lifecycle that includes decommissioning, and no record in the Environments Inventory that would make them visible to enterprise governance. Every environment that is created informally is an environment that will eventually become idle, orphaned, or ungoverned - a cost burden and a security exposure that the organization cannot see because it was never registered in the governance framework.

Best Practice

Require that every new environment instance be created through a formal environment provisioning process that establishes the governance foundations the environment requires before it is deployed. The provisioning process should collect and record: the environment type from the standard taxonomy and the semantic identifier for the instance; the application or solution the environment will serve and the corresponding APM portfolio record; the named Environment Instance Owner who accepts accountability for the environment from the moment of creation; the isolated-vs-shared model decision with documented rationale; the data classification of data that will be present in the environment and the governance controls applicable to that classification; the infrastructure sizing justification against the right-sizing guidelines for the environment tier; the expected lifecycle duration and the criteria that will trigger decommissioning; and the availability SLA applicable to the environment.

Record every new environment in the Environments Inventory at the time of provisioning, before the environment is made available to its intended users. An environment that is deployed before its inventory record is created is an environment that begins its operational life with a governance deficit that may never be remediated.

Benefit(s)

Formal environment creation processes produce environments that begin their operational lives fully governed rather than requiring retroactive governance establishment that is more difficult, less complete, and less reliably executed than governance established at provisioning time. Every environment in the inventory has a documented purpose, a named owner, a defined lifecycle, and a complete governance record from the first day of its operation. The organization’s Environments Inventory is accurate and current because environment registration is a required step in the creation process rather than an optional documentation activity that may or may not follow informal provisioning.
