AWS Foundational Technical Review (FTR) is a service offered by Amazon Web Services (AWS) to help customers design and operate reliable, scalable, and efficient systems in the cloud. During an FTR, AWS solutions architects review a customer's AWS environment to assess its overall architecture, operational excellence, security, reliability, performance efficiency, and cost optimization. The FTR also includes a comprehensive review of the customer's workload's architecture, implementation, and configuration. The primary goal of an FTR is to provide customers with recommendations for improving the architecture, security, and overall efficiency of their AWS environment. This review also helps customers to optimize their workloads and reduce costs. Additionally, FTR enables customers to identify and remediate any security or compliance issues that may exist in their AWS environment. AWS Foundational Technical Review is typically used by organizations that are planning to deploy new workloads in AWS or those that want to optimize their existing AWS environment. It is a valuable tool that can help customers to achieve greater success with their cloud deployments by ensuring that they are taking advantage of AWS best practices and optimizing their AWS environment for cost and performance.
