AWS Well-Architected

Build and evaluate your applications based on architectural best practices.

AWS Well-Architected Framework Reviews.

The Well-Architected Framework Review is an architectural assessment, based on the AWS Well-Architected six pillars, which support cloud architects in building secure, high-performing, resilient, and cost-efficient infrastructure for their applications.

As an AWS Well-Architected Partner, fourTheorem has the expertise to build high-quality solutions, implement best practices, check the state of workloads, and make improvements to fit business and customer requirements.

The six pillars:

  • Operational Excellence: Run and monitor systems to deliver business value while continuously improving processes and procedures. Identify gaps and employ best practices to enhance operations and customer outcomes.
  • Security: Protect information, systems, and assets through risk assessments, AI-generated security insights, automated monitoring, and mitigation strategies. Encompass people, processes, and data to build a strong security foundation.
  • Cost-Optimisation: Eliminate unnecessary costs by understanding spend over time, controlling fund allocation, selecting resources of the right type and quantity, and scaling to meet business needs without overspending.
  • Performance Efficiency: Ensure computing resources are used efficiently to meet system requirements. The strategy adapts to changing demands and evolving capabilities.
  • Reliability: Assess the ability to recover from failures, dynamically acquire computing resources to meet demand, and mitigate disruptions.
  • Sustainability: Improve sustainability impacts by reducing energy consumption and enhancing workload efficiency.

  • Understand and reduce risk: Identifying and addressing critical issues promptly helps maintain system stability and security, preventing potential disruptions that could affect business operations.
  • Continuous improvement: Regularly measuring systems against best practices and striving for continuous improvement leads to better product quality, increased customer satisfaction, and a more efficient and effective development process.
  • Faster build and deployment timeframes: Having a solid, reliable baseline infrastructure allows you to build and deploy applications faster, which is critical in meeting customer demands and scaling the system effectively.
  • Minimise system failures and optimise performance: Reducing system failures and improving performance ensures a more reliable and efficient AWS environment, leading to improved customer experiences and reduced downtime.
  • Reduce operational costs: Optimise architecture for cost and performance with dedicated guidance on designing and implementing applications, as well as recommendations on utilising AWS services to ensure they are cost-effective and meet performance requirements.

The Process:


Ahead of the Review fourTheorem will need to identify the selected workloads, access any relevant AWS accounts, prepare the relevant data and arrange the review with the customer.


During a one-day workshop, fourTheorem will meet with the customer and assess the current architecture. The review can be conducted onsite or remotely.


fourTheorem will prepare a report evaluating the workload against AWS best practices. The identified areas for improvement will be prioritised as either High Risk or Medium Risk and will form the basis of a Statement of Work to address the necessary improvements.


If the customer follows through with the recommended remediation with fourTheorem, they can receive $5,000 in credits from AWS to offset the costs of our professional services.
