Demystifying Persistent Storage Myths for Stateful Workloads in Kubernetes (blog.calsoftinc.com)
Published: Friday, 18 October 2019.  By:Sagar Nangare / Calsoft Inc.
Kubernetes provides workload portability. That is, any workloads should spontaneously run on any type of infrastructure where Kubernetes clusters are deployed. In the case of handling stateful workloads, it may not easy to set up persistent storage but it is not impossible. The Kubernetes community has addressed the issue for stateful services and different storage options with CSI along with dynamic provisioning of persistent storage using storage classes. These allow integrating remote block/file storage easily into K8S clusters and can run on any different K8S-based clusters.

Monitoring blocked and passthrough external service traffic (istio.io)
Published: Monday, 07 October 2019.
Understanding, controlling and securing your external service access is one of the key benefits that you get from a service mesh like Istio. From a security and operations point of view, it is critical to monitor what external service traffic is getting blocked as they might surface possible misconfigurations or a security vulnerability if an application is attempting to communicate with a service that it should not be allowed to. Similarly, if you currently have a policy of allowing any external service access, it is beneficial to monitor the traffic so you can incrementally add explicit Istio configuration to allow access and better security your cluster. In either case, having visibility into this traffic via telemetry is quite helpful as it enables you to create alerts and dashboards, and better reason about your security posture. This was a highly requested feature by production users of Istio and we are excited that the support for this was added in release 1.3.

A Practical Guide to Setting Kubernetes Requests and Limits (blog.kubecost.com)
Published: Monday, 07 October 2019.
Setting Kubernetes requests and limits effectively has a major impact on application performance, stability, and cost. And yet working with many teams over the past year has shown us that determining the right values for these parameters is hard. For this reason, we have created this short guide and are launching a new product to help teams more accurately set Kubernetes requests and limits for their applications.

KubeVirt Joins Cloud Native Computing Foundation (blog.openshift.com)
Published: Thursday, 03 October 2019.
This month the Cloud Native Computing Foundation (CNCF) formally adopted KubeVirt into the CNCF Sandbox. KubeVirt allows you to provision, manage and run virtual machines from and within Kubernetes. In joining the CNCF Sandbox, KubeVirt now has a more substantial platform to grow as well as educate the CNCF community on the use cases for placing virtual machines within Kubernetes. The CNCF onboards projects into the CNCF Sandbox when they warrant experimentation on neutral ground to promote and foster collaborative development.
