Architecture & Standards
Architecture Decisions, Made Explicit
The engineering standards NEOKADRIX applies across platforms: clear boundaries, durable state, verified media movement and releases that can be reversed.
System model
Control Plane and Media / Compute Plane
The control plane decides: identity, permissions, state and orchestration. The compute plane executes: ingest, processing and acceleration close to storage. They communicate only through typed contracts.
Standards
Engineering Standards in Practice
Service Boundaries
Each service owns a defined responsibility and its data. Other services interact with it only through its contract.
- Single owner per dataset
- No shared-table coupling
- Versioned interfaces
Reliable Data Storage
Core records are kept in durable storage. Related changes are saved together, while data rules protect consistency and changes to the data structure are reviewed before deployment.
- Consistent data updates
- Data integrity checks
- Reviewed structural changes
Coordinated Workflows
Shared work is coordinated between services. Temporary results help serve repeat requests efficiently, while core records remain in durable storage.
- Coordination between services
- Fast access to temporary results
- Durable storage for core records
Access Permissions & Audit
Access is granted by role with least privilege, and significant actions produce a structured audit record.
- Role-based permissions
- Attributable actions
- Structured audit trails
Deployment Isolation
Environments, tenants and workloads are isolated so that a failure or change in one does not propagate to another.
- Separated environments
- Containerized workloads
- Tenant isolation where applicable
Observability
Services expose health, throughput and errors so operators can see the state of the system rather than infer it.
- Health and readiness signals
- Structured logging
- Monitoring of critical paths
Rollback Discipline
Releases are phased and reversible. A release is not complete until its path back has been defined and tested.
- Phased releases
- Tested rollback paths
- Backward-compatible migrations
Media integrity
Atomic Media Movement and Checksum Verification
Large media files are never exposed in a partial state. Movement is staged, verified and committed as one controlled sequence.
Five-step sequence: stage the file, compute its checksum, verify against the source, commit atomically to the final path, and record the result.
- 01
Stage
Write to a staging location on the destination storage.
- 02
Checksum
Compute the checksum of the staged file.
- 03
Verify
Compare against the source checksum; mismatches are rejected.
- 04
Commit
Atomically move the file into its final path.
- 05
Record
Commit catalogue state and the audit event together.
Architecture Principles
Explicit system boundaries
Every service has a defined responsibility, owner and interface.
Control / compute separation
Decisions are made in the control plane; heavy work runs in the compute plane.
Typed contracts
APIs and events are versioned, typed and validated at the boundary.
Least-privilege access
Users and services receive only the permissions their role requires.
Multi-tenant isolation
Where systems serve multiple tenants, data and access are separated by design.
Auditable operations
Significant actions leave a structured, attributable record.
Storage-aware processing
Work is placed near the data to minimize large-file movement.
Observable services
Health, throughput and failures are measurable, not inferred.
Phased deployment
Change is introduced in controlled stages with defined checkpoints.
Reversible releases
Every release has a tested path back to the previous state.

Apply These Standards to Your Platform
An architectural review measures an existing or planned system against these standards and identifies the gaps that matter.
