In the pre-Kubernetes, pre-container world, backup and recovery solutions were generally implemented at the virtual machine (VM) level. That works for traditional applications when an application runs on a single VM. But when applications are containerized and managed with an orchestrator like Kubernetes, this system falls apart. That means effective disaster recovery (DR) plans for Kubernetes must be designed for containerized architectures and natively understand the way Kubernetes functions.

Being in the DevOps space, we're often asked questions about software deployment like, "What's the difference between continuous deployment and continuous delivery?", "What is continuous deployment?", and "Are continuous deployment and continuous delivery the same thing?" So first, let's start by clearly defining these terms.

In the world of containers and Kubernetes, observability is crucial. Cluster administrators need visibility into the infrastructure and cluster operators need to know the status of their workloads at any given time. And in both cases, they need observability into moving objects. This is where Metricbeat and its autodiscover feature do the hard part for you.

Another year of empowering DevOps teams has passed and what a year it’s been! I’d like to take a moment to reflect on the journey, the milestones and challenges this past year encompassed. The last year has been our most transformational to date. We’ve had a huge amount of ups and downs and I’m incredibly proud to say that we got through it and our organization is more resilient, more aligned in our vision and closer as a result.

Puppet is a Continuous Configuration Automation tool that’s you can use to automate the configuration of your entire infrastructure. You can use it to manage the configuration of anywhere from a few, to thousands of servers or devices. Puppet consists of two main components: The Puppet Server The Puppet server is where you create and store your configurations and define which nodes specific configurations will be applied to.
