Full migration guidance is available in the Kubernetes blog post: https://kubernetes.io/blog/2019/07/18/api-deprecations-in-1-16/

Prometheus Managed Services

Cloud providers now offer managed or integrated Prometheus services:

Microsoft Azure provides a preview integration of Prometheus metrics with Azure Monitor. Details: https://azure.microsoft.com/en-us/blog/azure-monitor-for-containers-with-prometheus-now-in-preview/

Alibaba Cloud launched a managed Prometheus service that includes zero‑touch exporter installation, pre‑built dashboards, full compatibility with open‑source components, and optional persistence in Alibaba TSDB for high availability. The service can be installed with a single Helm chart. Documentation: https://www.aliyun.com/product/arms and https://help.aliyun.com/document_detail/94622.html

Kubernetes Design Enhancement Proposals (KEP)

IPv6 support has entered Beta. Details: https://github.com/kubernetes/enhancements/issues/1138

Cloud Provider label is moving from Beta to GA, standardizing the cloud.provider label across clusters. Details: https://github.com/kubernetes/enhancements/blob/master/keps/sig-cloud-provider/20190215-promoting-cloud-provider-labels.md

Knative Project Updates

Knative Serving 0.8 is scheduled for release on 2020‑08‑06, focusing on availability and stability improvements.

Work is in progress to simplify direct event consumption from sources and to extend the Knative CLI for richer event handling.

Open‑Source Project Recommendation: Kopf

Kopf is a Python‑centric Kubernetes Operator framework that provides concise primitives for building operators with minimal code while abstracting low‑level controller details.
