We’re pleased to share that fourTheorem has achieved the AWS Migration and Modernisation Competency. So, what does that mean exactly? As an AWS Migration Competency Partner, we have a proven track record of delivering successful enterprise migrations. It also means we can leverage the funding and support available under the AWS Migration Acceleration Program to accelerate your migration and reduce your costs.
What is AWS MAP?
The AWS Migration Acceleration Program (MAP) is a structured framework AWS developed to help organisations migrate to the cloud in a way that reduces risk, controls cost, and builds a solid foundation for what comes after. It’s built on AWS’s experience supporting thousands of enterprise migrations, and it combines methodology, tooling, and, importantly, AWS funding to offset the cost of moving.
MAP follows three phases: Assess, Mobilise, and Migrate & Modernise. The Assess phase is about understanding where you are and building the business case. Mobilise is where you put the foundations in place – landing zone, security, governance, and the detailed migration plan. Migrate & Modernise is the execution phase, where workloads move, and the real modernisation decisions get made.
Now the interesting part. Depending on your workloads, MAP can unlock up to 25% of incremental ARR in migration investment, with additional incentives for Windows workloads, managed database migrations, and database modernisation.
Now the interesting part. MAP funding comes in two forms. First, partner cash funding to offset the cost of the Assess and Mobilise phases – up to 5% of ARR for Assess and up to 20% for Mobilise. Then, MAP Credits for the Migrate & Modernise phase are issued directly to you based on your tagged AWS spend. There are also additional incentives for VMware migrations, database and analytics workloads, and SAP or Oracle applications.
What the Competency means in practice
Looking for a migration partner that you can rely on? The Migration and Modernisation Competency requires demonstrating proven success. AWS has reviewed our customer engagements, assessed the outcomes we delivered, and validated that we have the expertise to migrate and modernise mission-critical workloads at scale.
In practical terms, it also unlocks access to the full MAP program benefits for our customers – the funding, the tooling, and the structured support that AWS makes available through accredited partners. That has a direct impact on cost and risk, particularly in the earlier phases where the groundwork is being laid.
This Competency sits alongside our AWS ECS Service Delivery and AWS Lambda Service Delivery designations, reflecting our specialisation in containers and serverless – two of the primary modernisation pathways on AWS once workloads are in the cloud.
How we approach a migration
Context shapes everything. Before any workload moves, we spend time understanding your business, your goals, and your current technology landscape – how you got here and where you want to go. That understanding informs how we prioritise workloads, how we structure the business case, and what the target architecture looks like.
We follow the MAP methodology closely, but the framework is only part of what determines whether a migration goes well. The other part is experience – knowing where migrations typically run into trouble and having the patterns and tooling to address it before it does.
Our Accelerators
Over the course of many migrations, we’ve distilled repeatable patterns into a set of accelerators – pre-built, production-ready tools that we deploy as part of our migration practice. They’re not off-the-shelf products; they’re extracted from real work and refined through use.
The Landing Zone Accelerator handles the setup of a secure, well-governed multi-account AWS environment; account structure, identity, federated access, security baselines, and networking. Getting this right at the start of Mobilise avoids a lot of rework later.
The Modernisation Factory is our approach to modernising large application portfolios at pace. It provides repeatable patterns and components for moving legacy applications to cloud-native architectures, and is designed for engagements where the volume of applications makes a one-by-one approach impractical.
The Financial Modelling Accelerator addresses a specific and common challenge in our sector: high-performance compute workloads running on on-premises infrastructure that were never designed for the cloud. It’s designed to move those workloads effectively, with elastic scaling, transparent cost visibility, and a significant reduction in infrastructure overhead.
The Data Platform Accelerator provides an architecture for managing and sharing analytical data at scale. Decentralised by design, with strong governance and provenance. It’s built around how data teams in complex organisations actually work, rather than how a centralised data architecture assumes they should.
The Enterprise API Accelerator is for teams who need to rebuild or expose their application layer as part of modernisation – getting a production-ready API platform configured and deployed without months of upfront architecture work.
Looking further ahead, our GenAI RAG Accelerator lets organisations pilot Generative AI use cases using their own data, building on the clean AWS foundation established during migration.
A note on our sector focus
Much of our migration work is concentrated in financial services and (re)insurance, where workloads tend to be complex, business-critical, and performance-sensitive. We’ve built significant domain expertise in this space – in catastrophe modelling, risk rollup processing, exposure management, and the wider (re)insurance technology stack. That experience shapes how we approach migrations in the sector and informs the design of several of our accelerators.
Oasis SaaS | Global Catastrophe Modelling Platform
We delivered the migration and modernisation of a global catastrophe modelling platform to AWS – a multi-tenant high-performance compute platform supporting over 300 CAT models, processing model sizes typically ranging from 300GB to 1TB. The platform is soon to be available industry-wide through Moody’s Intelligent Risk Platform and is in active adoption by global carriers, including Chubb, Sompo, and SwissRe.
Get in touch
If you’re thinking about a migration, whether you’re at the early stages of building a business case or already underway, we’re happy to have a conversation about where you are and what a sensible path forward might look like.
