Keeping data in motion

How Adyen re-architected their platform to improve throughput and latency by developing a highly consistent in-house streaming framework.

Adyen was processing close to 5 billion transactions yearly, and growing rapidly. As a result databases were straining under load and batch processes were constantly at risk of missing their scheduled deadline. This led to Adyen deploying a streaming data flow for file generation, reporting and analytics, effectively doing away with costly batch job processing and making sharding a cinch.

You heard of “new thing” called gRPC and promises that it will solve all issues for you, so now you are not sure if you should use it for breaking up your monolith to Microservices.

On the other hand, you have been using REST API’s for some time now, at least as a consumer, so maybe this would be better approach in Microservices waters, or would it?

Which one to chose and which one will fit your use case better?

Join me in this talk were I will try to explain both approaches, good and bad. I will give some points and tips, which will help you in understanding better which one will be better for you. By doing this I will also share some best practices for both approaches
