Enterprise Applications, IT Atlas

Overview

Enterprise applications are defined by their integrations and their data ownership. Each has an authoritative dataset, a set of interfaces, an upgrade cycle, and a business owner whose priorities drive availability requirements.

IT's contribution is lifecycle rigour: documented architecture, environment separation, tested upgrades, integration inventory, access model and recovery plan.

Security considerations

Integrate with SSO and remove local application accounts, especially administrative ones.
Map integrations and their credentials; service to service accounts are the least governed part of most application estates.
