Using SPIFFE and OPA to Authenticate and Authorize Workloads (Charlie Egan, Styra)
What’s the highest value platform feature you can offer your Kubernetes tenants? It might be standardizing workload identity and policy controls. In this session, we will discuss desirable properties for a workload identity and present a modern architecture built on SPIFFE and cert-manager which uses Open Policy Agent (OPA) for policy decisions. This should leave you with actionable ideas to help you re-evaluate your workload identity functionality and security posture.

Charlie has been working with in the Cloud Native space since 2018. He currently works as a Developer Advocate at Styra and on the OPA project. Charlie is interested in authentication and authorization across the stack (charlieegan3@hachyderm.io on Mastodon & @charlieegan3 on Twitter)

The Complexities of Database Caching at the Edge (Ben Hagan, PolyScale.ai)
Caching can be used as an effective solution to solve data-driven application performance issues, including expensive database queries and multi-region latency. Implementing caching however can be a complex and time consuming exercise, often ending in variable hit rates and consistency issues. In this talk we explore these challenges and how PolyScale.ai can offer a solution for automated database caching, globally.

Understanding Shift To Custom Kubernetes Resources (Kale Oum Nivrathi, JFrog)
In the era of containerization and orchestration, Kubernetes is highly brisking. The future of the orchestration platforms will be Custom Resources Definitions (CRD) and APIs. Whereas writing k8s operator is the best way of extending APIs for our application, Operators are clients of the Kubernetes API that act as controllers for a Custom Resource. Operator lets us extend the functionality of the Kubernetes API, enabling it to configure, create, and manage instances of applications automatically using a structured process. In this talk, we will take a deep dive into the capabilities of Kubernetes controllers, and lifecycle management, including backup, recovery, and automatic configuration tuning. We will also explore the uses of Kubernetes Operator Writing Controller logic and its unique way to manage application deployments as a use case.
