Srovnejto.cz needed to break free from a legacy monolith that slowed down innovation and growth. Stormit helped them transition to a fully serverless, event-driven architecture on AWS - unlocking the agility and scalability their platform needed.

Srovnejto.cz is a trusted multi-brand company and the leading platform for comparing financial products in the Czech Republic and Slovakia. With several brands and online portals focused on insurance, banking, and energy, they make it easy for people to find the right offer that fits their needs. Whatever stage of life you’re in, Srovnejto.cz helps you make smarter financial choices with confidence.

The company’s legacy on-premise system had begun to hold them back, making it difficult to expand and roll out new services quickly. To keep pace with their growth, Srovnejto.cz decided to move away from the outdated monolithic setup and rebuild their platform as smaller, more agile microservices on AWS.

Stormit designed a fully cloud-native, event-driven microservices architecture using services such as Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. After the successful migration, Stormit continues to support Srovnejto.cz by optimizing their AWS environment and managing costs, allowing their team to stay focused on innovation, expansion, and growth without being limited by IT infrastructure.

By moving to a serverless, event-driven architecture on AWS, Srovnejto.cz gained the agility and scalability needed to innovate faster. With Stormit’s support in optimizing their AWS environment, they can now focus on expanding services and delivering smarter financial solutions without being held back by legacy systems.
