Currently Pied À Terre, has a mature AWS architecture that is growing day by day.
One of the main benefits has been the integration with AWS managed services, such as: in the RDS database that helped to have backup and replication schemes from day one; Cloudfront that allows to distribute the content in the different regions for a better experience of the platform; S3 as an image repository.
Some other tools like auto-scaling, SSL load balancers, AWS Cognito integration have solved tasks in a standard and secure way. AWS Lambda for running microservices in different flows.
The speed with which AWS adds relevant services supports the decision of having chosen it.
