• Kubernetes Security Specialist Certification Now Available
  CKS is now open for registration and scheduling.
• Cloud Native Computing Foundation Announces 2020 Community Awards Winners
  CNCF and the projects lives by the community, these are the people who were outstanding the last year in serving the community.
• Cloud Native Survey 2020
  Container in production jump by 300% in comparison to the first report 4 years ago.
• Cloud Native Security White Paper
  The whitepaper intends to provide organizations and their technical leadership with a clear understanding of cloud native security.
• CNCF End User Technology Radar: Database Storage
  The technology radar is a quarterly published technology specific snapshot of some of the most relevant tools/systems. This time: Databases
• Cloud Native Network Functions Conformance Launched by CNCF
  The community has launched a new working group (WG) focused on Cloud Native Networking Functions (CNF). Their first target is to build CNF conformance and developed a new whitepaper on the use of cloud native technologies in telecommunications organizations
• CNCF and FinOps Foundation Collaborate to Advance Cloud Financial Management
  CNCF and FinOps Foundation find together to define FinOps best practices and standards to improve cloud financial management.

Networking

• iptables: How Kubernetes Services Direct Traffic to Pods
  The third part of the Kubernetes tackles how Kubernetes’s kube-proxy component uses iptables to direct service traffic to pods randomly. The previous parts of this network series give a deep insights on how Kubernetes creates IP addresses and publishes port.

Cloud-Native Industry

• Jetstack donates cert-manager to Cloud Native Computing Foundation
  cert-manager is a Kubernetes add-on to automate the management and issuance of TLS certificates from various issuing sources. Donating this widely used project to the CNCF will support its growth and visibility.

Containers & Orchestration

• awslabs/karpenter
  Meet this new early stage, an experimental project from awslabs. Karpenter is a metrics-driven autoscaler built for Kubernetes and can run in any Kubernetes cluster anywhere. It's performant, extensible, and can autoscale anything that implements the Kubernetes scale subresource.

Observability

• Kubernetes Service Level Objectives (SLOs) with Prometheus and Linkerd
  SLOs are a way for application developers and SRE teams to explicitly capture the risk tolerance for their application, by defining what level of failure is acceptable. Utilizing Linkerd gives you the possibility to provide consistent metrics for the things you want to measure.
