Modern architectures often consist of containers that run services. Those containers scale up and down depending on the demand for the services. These large software systems often use a technique known as event sourcing, where every change to the system is kept in an event log. When an event on the log is processed, several different data stores might be updated in response.
In these architectures, containers are interacting with each other. Multiple databases are responding to events in the event log. To connect these systems together, engineers can write small functions to pass data around–you might call these small connecting functions “glue.” Glue functions are a great use for a serverless tool such as AWS Lambda or Google Cloud Functions. As these glue functions grow in popularity, there is an increased need for an open source way to deploy serverless functions.
Sebastien Goasgoen works on Kubeless, a serverless execution tool built on top of Kubernetes. In this episode, we explore his take on the “serverless on Kubernetes” problem. This is a great companion episode to yesterday’s interview with Soam Vasani.
