Migrate to the cloud with confidence.

What is AWS MAP?

The AWS Migration Acceleration Program (MAP), is a proven cloud migration program designed to help move workloads to AWS quickly and easily, in a cost-efficient manner – with AWS funding available at each phase of the migration process, as well as significant discounts for several years after.

As an AWS MAP Partner with demonstrated technical expertise in delivering customer cloud migrations, fourTheorem can access migration support available under the AWS Migration Acceleration Program on your behalf.

Migrating to AWS unlocks efficiencies and operational benefits - but the process can be long, complex, and expensive.

MAP can accelerate your organisation’s cloud migration and modernisation journey through outcome-driven methodology, tooling, and financial incentives.

We follow a three-step approach to migration that uses proven frameworks to reduce the risk and cost for you.

A serverless architecture for high performance financial modelling

RenaissanceRe, one of the world’s leading reinsurance companies, specialises in managing risks associated with climate change, natural hazards, cyber threats, and societal upheaval. With $8 billion in gross premiums and $18 billion in capital under management in 2021, the company heavily invests in modelling expertise and technology.

Understanding deal and portfolio risk and capital requirements is a computationally expensive process that requires the execution of multiple financial forecasting models every day and often in real time. Each run (typically 5 daily) handles massive data, processing about 45TB and generating 600GB of output. Besides batch-based risk computation, real-time deal analytics are required for pricing and underwriting decisions. This involves running risk models on individual deals, sometimes thousands of times per day during peak periods.

Due to business growth, the number of contracts under risk has significantly increased, straining the on-premises compute resources. As a result, in 2020, RenaissanceRe decided to stop investing in the on-premises cluster and transition to AWS.

Partnering with fourTheorem, RenaissanceRe migrated the portfolio rollup process to AWS, utilising managed services and serverless compute. This transformation reduced the run time of one process from 10 hours to 1 hour and demonstrated the true potential of serverless AWS – the removal of the artificial ceiling the monolith represented, unleashing the power of the cloud.

The Benefits

Choose fourTheorem as your MAP partner and...

Cut Carbon Emissions

Self-owned and operated IT infrastructure and data centres are major sources of energy use. Moving workloads to the cloud can reduce associated carbon emissions by nearly 80%.

Accelerate Adoption

We are uniquely positioned to help companies make the most of the agility, breadth of services, and pace of innovation that AWS provides.

Reduce Costs

We can help you to offset the initial cost of migrations. AWS Partners can leverage MAP funding incentives to assist customers in achieving their business objectives with AWS.

Mitigate Risk

The biggest inhibitor to cloud adoption is a lack of skills. We can leverage AWS cloud best practices to reduce the complexity & costs of your migration and improve the chance of success.
