Single-tenant clouds on tap for Navy, Marines

The Navy and Marine Corps are moving to individual, dedicated Microsoft 365 environments to improve identity and credentialing efforts, according to a department memo.

In that document, Navy Department CIO Aaron Weis explained that using a dedicated Microsoft 365 cloud for the Navy and Secretariat, and another for the Marine Corps would save money, and be the most efficient way to account for users while also allowing for future collaboration and productivity services across multiple networks.

"Moving to single tenancy is the most expeditious way to ensure users are accounted for and migrated to the cloud-based office suite of services offered by Microsoft 365. Single tenancy reduces cost and complexity, enables effective command and control, and increases the efficiency of federation management with external DON tenants," Weis wrote in the memo that was publicly released Sept. 15.

The move is also critical to the Navy and Marine Corps implementing their identity, credentialing and access management strategy, including reducing individual aliases and adopting a "one email for life" posture through single directory management.

"Directory management tools can also serve as a source of identity management for applications re-factoring for cloud that are interested in flexible access management and single sign-on. Starting with these capabilities will allow the DON to clean up identity, and to learn and evolve as our understanding grows," the CIO wrote.

The dedicated tracts, however, won't impede using productivity services across multiple networks, according to the memo. Additionally, the Navy's chief information office said it will review any individual testing, procurement or implementation of Microsoft 365 user groups and realign them to this approach.
