Consulting and optimization for transforming into cloud-only setup using AWS toolstack

Immowelt GmbH / AVIV Group

Immowelt runs a hybrid setup of various Windows and Linux servers to provide their real estate trading platform to enterprises and end users all over Europe.
To ensure maximum future IT capabilities, the customer wants to leave all local datacenters and systematically cut the two big monolith platforms into microservices running on the AWS native tech stack.
The complete AWS infrastructure is maintained with Terraform, versioned in Git repositories and deployed with pipelines via GitLab, Jenkins or CircleCI.
Wherever possible, the central Auth0 provider Okta is to be implemented, even in legacy applications.
On their journey to provide a smooth, seamless employee tech stack, I supported them in making key decisions by integrating MS Azure Intune and Okta. This way the newly onboarded users experience an automated path to get their new workstations up and running exactly where they need to work.
