Why Kubelet TLS Bootstrap in Kubernetes 1.12 is a Very Big Deal

Kubelet TLS Bootstrap, an exciting and highly-anticipated feature in Kubernetes 1.12, is graduating to general availability. As you know, the Kubernetes orchestration system provides such key benefits as service discovery, load balancing, rolling restarts, and the ability to maintain container counts by replacing failed containers. And by using Kubernetes-compliant extensions, you can seamlessly enhance system functionality.

How to Triage Test Failures in a Continuous Delivery Lifecycle

Continuous testing has evolved to become an important phase in modern application development and delivery. When we at Sumo Logic sketched out a plan to start delivering our microservices continuously, we knew we needed to define a delivery pipeline, which would run our automated tests and provide feedback in early phases of development.

Migrating from Monolithic to Cloud Native Applications

Lately, the public cloud services market has created one of the biggest disruptions in the tech market. In fact, as per Forrester Data, public cloud services forecasted a 22% CAGR in the public cloud market from 2016 to 2020.
