AEVI - More resilient cloud infrastructure solution

Aevi currently runs multiple database instances, in various staging environments and regions - all using Oracle EE licensing. There are two types of databases - mission-critical transactional database and less-critical support database. The transactional databases have an extreme requirement for availability, minimum lag time and durability of data. The support database on the other hand needs to be cross-regionally replicated because it utilizes a synchronization mechanism that needs to be migrated to a cloud as well. Therefore, any cloud solution must take these requirements into account and propose two very different strategies.

The Trustsoft team assessed the current on-prem database layer and designed and tested the new AWS cloud-based solution that would cover all requirements and would be stable and ready to support any future Aevi’s ventures.

The databases are crucial components of the Aevi’s mission critical systems that are frequently subjected to highly variable heavy workloads (up to 1000 requests per second). Our solution reflects a special need for a speedy, scalable, and resilient architecture that is capable of cross-regional backup, data synchronisation and disaster recovery.

In order to bring Aevi’s customers the best connectivity with minimal lag times, the solution we proposed is now deployed in European, the North American and Asian AWS regions.

Our team also proposed various metrics and KPIs to thoroughly test the proposed solution. In cooperation with the client, we built a POC (proof-of-concept) environment into the production on-prem environment in AWS and made sure that it can handle presumed traffic.
During this phase of the POC, our team also re-platformed the critical database into the open-source PostgreSQL and also re-platformed the supporting database for Oracle SE licensing. The total value of savings from  the change of the licenses is $ 1.5 million per year.
