Migrate to the cloud with confidence.

What is AWS MAP?

The AWS Migration Acceleration Program (MAP), is a proven cloud migration program designed to accelerate your organisation’s migration and modernisation journey through an outcome-driven methodology.

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 enterprise migrations can be complex and time-consuming.

MAP provides tools that reduce costs and automate and accelerate execution, as well as tailored training approaches, content and AWS investment.

As a MAP Partner, we follow a three-step approach to migration that uses proven frameworks to reduce the risk and cost associated.

Migration Methodology

Assess Readiness

Develop the business case for migration.

  • Conduct a Migration Readiness Assessment (MRA)
  • Identify desired business objectives & deliverables
  • Align key stakeholders
  • Complete cost projection for running applications in AWS

Mobilise Resources

Build an operational foundation for your migration.

  • Create a detailed migration plan – address gaps identified by the MRA
  • Create proof of concept (POC) implementations
  • Build AWS Landing Zone architecture
  • Complete Well-Architected Review for all workloads
  • Run applications in production capacity
  • Develop cloud capabilities and skills
  • Automate migration with AWS built-in tools, fourTheorem’s Enterprise Cloud Accelerator and Fission

Migrate & Modernise Workloads

Execute the migration plan developed during the mobilise phase.

  • Design, migrate, and validate planned workloads to AWS
  • Re-host, re-platform, and re-architect as necessary
  • Use the patterns, processes, tools, resources, and methodology identified and tested during the Mobilise phase

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

Achieve cost savings by migrating your infrastructure and legacy applications to the cloud. On average, customers who make this transition save 31% on their infrastructure expenses.

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.
