This session provides an in-depth exploration of primary serverless paradigm for web apps — Function-as-a-Service (FaaS) and how achieve it in the Kubernetes world.

We will explore the main options for approaching these in the Kubernetes ecosystem and discuss the limitations and possible benefits of each approach. Is WASM viable today? Should we benefit from Knative feature limiting in-flight requests? Or can we go with a vanilla autoscaling? The session will present a few simulations regarding different use cases suitable for each workload highlighting differences and attributes that make the solution a good fit in terms of performance, stability, and budget.

We will uncover the current blockers with non-WASM technologies and evaluate whether WASM can address them effectively today – or if it remains a promise for the future.
