Four Techniques Serverless Platforms Use to Balance Performance and Cost
Erwin van Eyk, InfoQ

Serverless computing is for many the logical next step in cloud computing, moving applications to a set of higher-level abstractions and offloading more of the low-level operational work to the cloud provider (regardless of whether that is a public one or an internal infrastructure team). This post gives you an idea of what is going on under the covers of the current state-of-the-art serverless platforms—especially with regards to performance and how you can influence it.

Kubernetes Security with Liz Rice
Jeff Meyerson, Software Engineering Daily

A Kubernetes cluster presents multiple potential attack surfaces: the cluster itself, a node running on the cluster, a pod running in the node, a container running in a pod. If you are managing your own Kubernetes cluster, you need to be aware of the security settings on your etcd, your API server, and your container build pipeline. In today’s show, Liz gives an overview of the security risks of a Kubernetes cluster, and provides some best practices including secret management, penetration testing, and container lifecycle management.
