Abstract

The client is a major developer of payment services, retail cash registers and a leading partner for campaign driven marketing in Swedish supermarkets and other retailers. Faced with the challenge of migrating its critical workloads to the cloud, the client engaged Omegapoint to help lead the effort. Together we established a robust and secure landing zone and successfully migrated the majority of their on-prem workloads to AWS. 

Background

The client made the strategic decision of migrating their business workloads to the public cloud in order to realise improvements in operational resilience, staff productivity and ultimately their business agility. There was a special concern to ensure that the architecture would be not only cost-effective and scalable, but also provably secure, as many of the clients partners are supervised financial institutions.

The Solution

Together with the client, we established a robust landing zone, with a secure hybrid network setup, cloud governance and security tooling. We played a pivotal role in crafting and executing an ambitious migration program, that would continue to serve as a foundation for scalable future growth, improved team efficiency and a strong security posture.

• We set up a robust Organization structure with Control Tower and SCP:s.

• We establisheda resilient hybrid network with optimized performance and redundant connectivity to seamlessly integrate with the existing on-premises infrastructure throughout the migration phase. On-prem connectivity was established through AWS DirectConnect with a failover AWS Site-to-site VPN. Everything connected through AWS Transit Gateway.

• We meticulously mapped services and dependencies within the IT landscape. We helped to organizeeverythinginto logical workloads,to ensure a future-proof organizational and account structure.Workload VPC’s have been segmented to fit the least-privilege requirement ofeach individual workload component.

• We enabled and calibrated central security services, such as GuardDuty, Identity Center, Macie, CloudTrail and Security Hub.

Results and benefits

Omegapoint delivered a highly scalable solution that met the security needs of the client and their stakeholders. We helped the client reach a stable Cloud Operating Model and set on a path of continuous modernization. The client has realised significant cost savings, efficiency improvements and overall increased business agility.
