The AWS public cloud would bring a scriptable infrastructure, resilient with AWS Regions and Availability Zones, to build redundancy into the new tax calculation service engine. But lifting and shifting an application to the AWS public cloud to build robust services requires an entirely new mindset. Further, AWS’s serverless public cloud technologies require a unique set of application development processes. To ensure the success of their SaaS-based, tax calculation service, the Client partnered with Anexinet to devise a strategy for migrating the Saas offering from a private cloud to an AWS public cloud.
Anexinet first built the SaaS application in a private cloud, then migrated the application once the business decision was made to move the workload to AWS. Naturally, the application required modification to be optimized for the public cloud. Once in the public cloud, new features were added to take full advantage of the AWS services.
