The operating system is the mission's foundation.
Every capability above it inherits the quality of the Linux layer. AASHU delivers that layer with fleet discipline: repeatable builds, managed configuration, planned upgrades, and measured performance — from a single enclave to hundreds of nodes.
What this line covers.
Focused engineering with clear outcomes, documented implementation, and a path for your team to own the result.
Deployment & provisioning
Kickstart, cloud-init, image-based, vendor-native, and automation-driven builds producing consistent, documented systems on demand.
Version migrations
Cross-distribution upgrades and RHEL major-version migrations in planned waves: dependency mapping, rehearsals, and rollback per wave.
Configuration management
Fleet configuration standardized and enforced as code — drift detected, deviations explained.
Patching & lifecycle
Patch baselines, package and advisory management, and maintenance-window discipline with health checks.
Performance engineering
Kernel, storage, and network tuning driven by measurement, with before/after evidence.
Identity integration
SSSD, IdM/AD join, Kerberos, and sudo policy — centralized authentication done right the first time.
What you receive.
Three ways to bring the capability in.
Fixed-scope project, monthly retainer, or staffed capacity embedded with your program.
Defined outcome, defined price
Scope, deliverables, and exit criteria agreed before work starts.
Reserved monthly capacity
Ongoing operations and expertise without a new contract per task.
Engineering on-program
Embedded delivery, including cleared environments where required.
