Compatibility
Application behavior, database objects, procedural logic, drivers, tools, integrations, transactions, and errors.
PROOF OF CONCEPT
Turn product capability into a workload decision.
A Halo PoC defines the application, target architecture, and acceptance criteria before testing compatibility, performance, continuity, distributed behavior, and day-to-day operations.
Five steps to a defensible decision
Frame the decision
Name the application, source product and version, business reason, owners, decision date, and non-negotiable requirements.
Map the dependency surface
Inventory objects, procedural logic, drivers, frameworks, integrations, transaction behavior, data profile, workload, and operating dependencies.
Select the Halo architecture
Choose the mode, topology, replication and recovery design, distributed components, operating environment, exact build, and optional modules in scope.
Run representative tests
Test application behavior, integrations, workload, failover, backup, restore, PITR, diagnostics, and operator tasks under agreed conditions.
Record the decision
Mark each material requirement passed as tested, passed with remediation, unsupported in scope, or not tested; assign owners and retest conditions before recommending proceed, remediate, or stop.
A demo and a PoC answer different questions
| Demo | Proof of concept |
|---|---|
| Introduces documented capabilities | Tests a defined workload |
| Uses prepared product material | Uses representative application inputs |
| Helps decide whether to investigate | Helps decide whether to proceed |
| Does not establish application fit | Produces scoped evidence and exceptions |
Run the lanes that affect the decision
Workload
Representative query mix, concurrency, batch work, resource use, stability, and agreed performance measures.
Continuity
Replication, failover, reconnect, backup, validation, restore, PITR, and former-primary rejoin.
Operations
Monitoring, HWR, diagnostics, maintenance, resource controls, administration tools, and ownership.
Distributed topology
DLB, TWR, HSM, or HDS routing, failure, consistency, placement, and lifecycle behavior when applicable.
What a useful PoC leaves behind
- Source and target inventory
- Requirement-to-test matrix
- Reproducible environment record
- Observations and retained evidence
- Compatibility and exception register
- Remediation, ownership, and retest plan
- Proceed, remediate, or stop recommendation
