AWS Platform and Microservice Modernization with 45% Cost Saving

-Increasing and out-of-control cost levels of AWS infrastructure and tools without strong coorelation with new clients and business growth -Lack of visibility and observability within the system and product – no E2E monitoring, no SLO’s defined and good business dashboards and escalations -Lack of reliability – no SLO’s defined, no clear E2E flow monitored and defined -Performance issues and ongoing incidents – due to monolithical design of the app, legacy code and technical debts and unmaintained areas of the system and its underlying infrastructure -Poor technical knowledge and understading of the infrastructure in in-house teams -Legacy code and infrastructure with plenty of technical debt, started but unfinished initiatives and no Infrastructure as Code defined

1. Migrate from legacy container infrastructure to AWS EKS (Kubernetes) for greater flexibility and insights into the application 2. Optimize AWS Infrastructure Costs and stabilize the trend of cost increasing 3. Optimize tooling costs (mainly Datadog and CircleCI) 4. Maintain the old (legacy) monolithical core of the application and develop new microservices 5. Migrate from Circle CI to Github Actions 6. Train on-site teams on SRE principles and using and implementing Kubernetes and AWS Cloud Native approach​

After 12 months of cooperation and becoming a strategic technology partner for Leeroy we significantly modernized the platform, limited amount of legacy code and technical depts, cut the AWS and tooling costs by 45% and increased the level of competences of Leeroy engineers significantly by applying DevOps Mindset and SRE principles. Many business challenges were still to be faced and new technologies to be implemented. In 2023 the platform and core development was officially moved to new owner of Leeroy – Caspeco who aquired the Leeroy Group AB company in february 2023 and officially took over the product and platform development.
