Feature flags can be surprisingly complicated

Feature flags are usually an after-thought when it comes to building applications. However, there is an entire army of developers that think otherwise. There is now an small set of companies that aim to provide feature flags as a service. There is now even a project in CNCF that aims to standardize this in order to ensure that users are not bound to a single provider. This talk aims to cover this (and more if time permits)

Using Emulators for Testing Google Cloud Datastore

Talk is about the situation where we would want to test an application that relies on Google Cloud Datastore locally. Google Cloud Datastore is a cloud based service - which raises the question of how a developer can test it locally, ideally without requiring to create a separate Google Cloud Project to safely test the changes.

Deploying apps using workload identity on GKE

Talk on introducing audience to deployment of applications on Google Kubernetes Engine. The application being used for demo would need to contact a Google APIs. The demo would consist having the application deployed in a Kubernetes cluster without needing a service account file for authentication of api requests.
