Cloud and integration architecture
Most enterprise pain lives between systems. We design the contracts, messaging, identity and hosting patterns that let services change independently and fail safely.
In practice
what you end up working with
| Interface | Owner | Health |
|---|---|---|
| Payments API v2 | Payments team | Healthy |
| Customer events | Customer team | Healthy |
| Partner file feed | Finance | Retiring |
| Legacy sync | Unassigned | Needs owner |
The problem
A change in one system breaks three others, and nobody is sure which interfaces are still in use.
What it usually looks like.
Systems that each work on their own are joined by point-to-point links, file transfers and manual steps. Nobody can list every integration, so every change is a risk, and outages are found by customers first.
When to ask for it
- You are adding a new system, partner or channel and need it to fit cleanly
- Integrations fail in ways that are hard to trace
- You are moving workloads to the cloud, or between cloud accounts
- New message standards, such as ISO 20022, are arriving in your sector
Scope
agreed in writing before work starts
What the work covers.
In scope
- An inventory of systems, interfaces and data flows that matter to the change
- API and event contracts, with ownership and versioning rules
- Messaging and integration patterns, including retries, ordering and reconciliation
- Cloud account, network and identity structure, with security and cost guardrails
Not included
- Running your integration platform day to day
- Licensing or reselling integration products
Approach
small steps, each one reversible
How the work runs.
- Start from the business events and the systems that care about them
- Agree contracts before anyone builds, and give each contract a named owner
- Design for failure: what happens when a system on either side is slow or down
- Prove the design with a thin working slice before it is rolled out widely
Every engagement also includes decision records, tested releases, documentation you own and a planned handover. How we work
Deliverables
each one ends with something you keep
What you keep.
Deliverables
- API and integration contracts
- Event and messaging design
- Cloud account and network structure
- Security, resilience and cost guardrails
What it is for
- Integrations you can list on one page, each with an owner
- Systems that can change without breaking each other
- Failures that are contained, visible and recoverable

Patterns
- Connecting fragmented services C: Illustrative
- Moving batch integrations to real time C: Illustrative
Often paired with
- Platform modernisation Move off ageing systems in steps, without a risky big-bang rewrite.
- Data foundations Give data clear owners, shared definitions and pipelines people trust.
