Cloud & Resilience
Cloud & Systems Architecture
Plan how your applications, data and infrastructure work together. We assess your current systems, compare practical options and define an architecture or migration plan around your operating needs and budget.
- Who it helps
- Businesses connecting applications, reviewing cloud or hosting arrangements, modernizing systems or preparing a migration.
- What you receive
- Architecture diagrams, an integration map, an operating cost comparison and a delivery or migration plan with clear responsibilities.
- How it works
- We review your systems with your team and suppliers, compare designs and plan delivery. Implementation and ongoing support are agreed in the scope.
When you need architecture support
Systems can work individually while the connections between them create problems. Teams enter customer information twice, integrations fail without an owner or a migration depends on an undocumented application. Understanding those dependencies helps you choose where to invest.
We help businesses modernize connected applications, review hosting arrangements and prepare for integration or migration. The aim is a design your team can operate and support, with clear trade-offs and a practical route from the current system.
Signs your systems need a review
- Teams cannot explain where important data originates or which system owns it.
- A platform change affects multiple suppliers, applications or customer journeys.
- Availability expectations, backup arrangements and recovery responsibilities do not match.
- Infrastructure costs grow without an agreed relationship to demand or service requirements.
What we assess
We map users, applications, data stores, integrations, infrastructure and external dependencies. The review covers access, performance, monitoring, backup and recovery, including how failures are detected, who is notified and how work is restored.
We compare cloud and hosting options with your current arrangement, including retaining and improving it. Design choices consider setup and operating costs, your team’s capacity, the ability to move between providers and the consequences of failure. Recovery objectives reflect your business’s tolerance for interruption and data loss.
What you receive
We select the outputs around the architecture, integration or migration decision you need to make.
Architecture & integrations
- Current and proposed architecture diagrams showing system boundaries, key decisions and performance, availability and reliability requirements.
- An integration and information-flow map identifying where data moves, which system owns it and the dependencies between services.
Migration & recovery
- A migration plan with the sequence of work, verification checks, switchover responsibilities and conditions for rolling back.
- Agreed recovery objectives and the checks needed to evaluate restore procedures and critical dependencies.
Costs & operating ownership
- An options comparison with cost assumptions covering setup, migration and ongoing operation.
- Defined operating and support responsibilities, with documentation for implementation and handover.
How we work
We agree the scope, information access, responsibilities and review points before work begins. A limited technical investigation can be scoped where a specific integration or migration risk needs closer examination.
Understand the current systems
InterPro: Review system diagrams, configuration summaries, usage and incidents. Map dependencies and clarify the requirements that affect the design.
Your team: Identify system and supplier owners. Share available documentation and explain critical workflows, budget constraints and interruption tolerance.
Compare practical designs
InterPro: Assess a manageable set of options, including improving the current arrangement. Explain the trade-offs in cost, performance, recovery and operating effort.
Your team: Check assumptions with your team and suppliers. Confirm priorities, operating capacity and the requirements the design must meet.
Plan delivery and handover
InterPro: Sequence the work and define acceptance checks, migration responsibilities and rollback conditions. Document how the proposed system will be operated and supported.
Your team: Confirm delivery owners, approve change windows and acceptance criteria and agree who can authorize switchover or rollback.
Engagement options
Choose a focused architecture review, a modernization and migration design project or scoped implementation coordination. Your existing engineering team and infrastructure suppliers can deliver against the agreed design and acceptance plan.
Implementation work and ongoing support are included only when agreed in the scope. Continuous monitoring, emergency coverage and specialist security testing require explicit arrangements with the responsible providers.
Measuring results
Measures may include response times for important user journeys, failed integrations, recovery-test results, operating cost, manual handoffs and completeness of operating documentation. We agree baselines, targets and measurement conditions for the engagement.
Testing and operating evidence show whether the implemented system meets its requirements. The design and handover plan define what needs to be checked, including recovery and rollback where relevant.
Illustrative scenario: connecting sales and customer accounts
Imagine a growing business that re-enters order details between its website and customer-management system. This is a hypothetical example of how an architecture engagement could work.
The scenario describes proposed work. Reliability and reductions in manual effort would need to be demonstrated through testing.
- The decision: connect the existing systems or replace part of the setup?
- Our approach: map the order journey, review available integrations and data ownership, and compare costs, support needs, and failure handling.
- What you would receive: an options assessment, a proposed system design, and a staged implementation and recovery plan.
- What we would test: sample orders, duplicate records, failed transfers, and recovery before recommending a wider rollout.
Relevant platform experience
For InterProWebHost, an affiliated operating business, we retained the existing WordPress and WHMCS platforms and coordinated focused customization across the public website, ordering and customer accounts. Completed work includes custom themes and an upgraded WHMCS 9 customer-management system.
The core website and customer platform are live. This work provides a practical reference for connecting the customer journey across systems and coordinating platform delivery. Relevant commercial relationships are explained during recommendations; an engagement does not require moving to a particular hosting or cloud provider.

For the Website Traffic Security development workstream, we completed AWS architecture and configuration, a service scope and system model, an evaluation framework and a staged roadmap. Integration planning addressed website setup, security-rule management, customer administration, support and recovery.
The offering remains in development. Production integration, acceptance testing and customer security outcomes are not yet established. The roadmap sets out validation work before wider release.

What should we prepare before starting?
Bring the system or migration decision, the applications involved and any deadlines or budget constraints. Existing diagrams, supplier details, cost summaries and incident records are useful where available. We agree any further information and system access needed as part of the scope.
How long does an architecture engagement take?
Timing depends on the number of systems, the available documentation, supplier involvement and whether technical investigation is needed. We agree the schedule and review points in the proposal. Implementation and migration windows are planned separately where included.
How are fees agreed?
Fees are set out in the proposal alongside the scope, deliverables, responsibilities and timing. The initial conversation helps establish whether you need a focused review, a wider design or implementation coordination. Relevant infrastructure and supplier costs are considered in the options assessment.
Does the service include implementation and ongoing support?
Architecture and delivery planning define what needs to be built or changed. Implementation, migration execution and ongoing support are included only when agreed in the scope, with responsibilities allocated to InterPro, your team and suppliers. Monitoring, emergency coverage and specialist testing need explicit service arrangements.
Do you only design systems that run in the cloud?
No. The assessment follows the application's requirements, dependencies and operating context. Existing hosting, managed services, cloud platforms and mixed arrangements can be compared where they are relevant options.
Can our current supplier implement the design?
Yes. The engagement can define design and acceptance criteria for implementation by your team or existing supplier, with InterPro IT Consultants providing scoped coordination or review.
Will a migration require downtime?
That depends on the systems, data flows and migration method. The plan examines interruption tolerance, synchronization, verification and rollback. Any downtime commitment requires a specific design and tested delivery arrangement.
Are backups enough to establish recovery readiness?
Backup coverage is one input. Recovery planning also needs restore procedures, access, dependencies, accountable owners and evidence from an appropriate recovery test. Recovery objectives should be agreed with the business and checked against what the system can demonstrate.
