What Does Combine Solve?
Delivering commercial software to the classified National Security sector cloud regions (such as C2S, SC2S, Azure Secret / Top Secret, and others) is very difficult because there are high technical barriers to entry, organizational policies and workforce limitations.
Technical
Barriers
Technical
Barriers
The National Security sector’s classified cloud regions (C2S, SC2S, Azure Secret / Top Secret and others) have intrinsic technical differences that often make them incompatible with commercial cloud native software and solutions.
Organizational
Policies
Organizational
Policies
Different members of the National Security sector have disparate rules and processes governing the access and administration of classified cloud regions. This makes it a challenge to support a consistent software baseline.
Workforce
Limitations
Workforce
Limitations
Many cleared engineers are new to cloud technologies and existing commercial cloud experts lack National Security clearances or citizenship to work in classified cloud regions. There is also an increasing decline in the number of clear software developers/engineer tue to various economic and social factors.
Combine bridges the technical gaps between cloud regions, accounts for organizational differences, and provides access to a broader workforce with the skills needed to deliver modern cloud engineering.
Migration / DevOps
Environment
Technical
Emulation
Combine reproduces technical differences that exist between classified cloud regions and their commercial counterparts such as:
- Authentication / Authorization
- Service Parity
- Air Gapped Networking
- Cloud Service Endpoints
Unclassified / Cloud
Native
