Eurowag – from on-prem to AWS with MAP

Their solution was on prem, where they were running multiple applications and database, that was used by Eurowag’s partners. Database was also running in Oracle, which was not only expensive but very limiting in terms of compatible services. Due to a large amount of data collected through the years which were on servers, Eurowag was a bit worried about the migration that was needed.

Eurowag’s mission was to provide seamless and secured services for their partners and the ability to add more partners. Their solution was based on the two main applications:

• PMG (payment management gateway) that serves as authorisation centre
• database – which runs in Oracle

We were asked to propose the best, scalable and the most efficient and secured solution on the AWS cloud and provide it without the system outages. We were also informed that the client was not happy with the Oracle database solution. After the first analysis and the information obtained, we offered Eurowag to join our AWS Migration Acceleration Program (MAP).

The Migration Acceleration Program (MAP) is a comprehensive and proven cloud migration program based upon AWS’s experience migrating thousands of enterprises and SMD customers to the cloud and on an outcome driven methodology.

• rapid evaluation of current workload and infrastructure
• estimation of cloud solution costs 
• company readiness for cloud migration
• discovery of critical knowledge gaps
• fast prototyping and evaluation of the target solution 
• security and compliance assessment

After the assessment phase in MAP we built the whole new network infrastructure in the AWS cloud. We ensure the communication between modules through the network of load balancers, transit gateways and VPNs. We also prepared special access through more than 130 VPNs for Eurowag’s partners, each of them has their own 3 secured communication environments for main, backup and test productions.

By moving apps and data to AWS we removed the dependence on the third-party datacentre, optimized the cloud fee costs and created scalable and high available environment. Transferring database from Oracle to PostgreSQL we enabled client to benefit from the use of compatible services. We also simplified the onboarding of the new partner into the system with automated templates. The infrastructure is delivered as a code (IaC), the deployments and distribution are automated.
