Kubernetes offers automation, scalability, and flexibility for managing your containerized applications. However, its distributed architecture makes it difficult to manage at scale. As the number of clusters and nodes increases, so does the complexity. Common challenges include maintaining uptime, resource scaling, security and governance, auxiliary cluster software deployments and lifecycle, and more. In this session, we’ll explore best practices for operating Kubernetes at scale and the efficient methods for managing a Kubernetes cluster in production. Additionally, we’ll discuss some new advancements of managed Kubernetes services, the key use cases they serve, and recommended configurations.

Cloud native, container-based microservices are the new norm for application architectures. Multicloud is the new norm for cloud consumption. Combine these two and you end up with significant challenges: How do I manage costs and complexity while deploying to multiple clouds? How do I know if my app is running properly? If my app isn't running smoothly, how do I find the cause of the issue? How do I move an app from cloud to cloud? In this session, we’ll discuss developing, deploying, and operating cloud native applications using Verrazzano—an open source container platform built from well-known, community-driven projects—for DevOps with cross-cloud consistency.

March 2023

Tools based on extended Berkeley packet filter (eBPF) kernel technology are getting more popular for cloud native applications, and new use cases for networking, monitoring, and security tools are arising.
