Mature multi-tenant SaaS platform
Enterprise SaaS Platform Assessment and Azure-to-AWS Target Architecture
Overview
Performed an AWS MAP Assess engagement for a mature Azure SaaS platform, producing current-state findings, a conceptual AWS target, migration strategies, waves, governance considerations, TCO inputs, and risks.
Context / Problem
A mature multi-tenant SaaS platform and its identity and access capabilities needed a credible view of migration feasibility from Azure to AWS. Decision-makers required current-state evidence and a target direction without confusing an assessment with a build-ready implementation design.
My Role
I contributed architecture assessment, discovery, dependency analysis, migration strategy, conceptual target-state design, governance and identity considerations, hybrid connectivity, wave planning, cost inputs, risks, and stakeholder decision material.
What I Did
- Structured current-state discovery across platform components, dependencies, identity, operations, and readiness.
- Applied migration-strategy and feasibility reasoning to workload groups and designed a conceptual AWS target.
- Produced decision inputs covering governance, hybrid connectivity, waves, TCO considerations, dependencies, and risks.
Architecture
Azure current state and dependency inventory feed an assessment and decision model. That model connects migration strategies to a conceptual AWS target and to wave, governance, identity, connectivity, cost, and risk considerations. The diagram deliberately ends before build-level design.

The target is conceptual assessment output, not a build-ready implementation design.
Key Decisions / Trade-offs
- Separate assessment from implementation design
- A conceptual target was sufficient for feasibility and direction while avoiding false precision before Mobilize and detailed discovery.
- Model identity and governance early
- For a mature multi-tenant platform, access and organizational controls shape migration feasibility as much as compute placement.
Implementation Scope
The engagement completed assessment and conceptual target-architecture work under an AWS MAP Assess scope. It produced migration decision material and planning inputs; it did not implement an AWS landing zone, migrate workloads, or enter a Mobilize delivery phase.
Safety / Security / Governance
Identity, access, governance, tenancy boundaries, hybrid connectivity, and risk were assessment dimensions. Public reconstruction uses generic platform descriptions and omits client identity, system names, inventory details, costs, and confidential findings.
Scope Boundary
This was an assessment plus conceptual target architecture. The result was not a build-ready final design and did not include landing-zone implementation, workload migration, or an AWS MAP Mobilize phase. No implementation or realized business outcome is claimed.
