What is DevOps?

DevOps is a set of various tools, practices, and ideals that combine software development (Dev) and IT Operations (Ops) into a single unifying force. It allows for better collaboration between developers, operations teams, system administrators, and system engineers. Their streamlined goal is to continually provide a high-value software product to the customer at high speed while monitoring and improving the overall process than using traditional software and infrastructure management.

What is Service Mesh?

A service mesh is an additional infrastructure layer that provides a means of communication between all services in a given application. It is typically deployed as a series of proxies alongside each service instance. Since the service mesh proxies are deployed alongside the application services and not as part of it, they are often referred to as sidecars. This means that as a whole, these sidecar proxies are a mesh network and an infrastructure layer separate from the application. A service mesh not only brokers communication between all services in an application but, since all requests, both internal and external, pass through it, it provides a means for handling many tasks that can be obfuscated away from the application.

The web-based Kubernetes console is an interface that provides information about the state of the Kubernetes cluster. The dashboard is also used for deploying containerized applications as well as for general cluster resource management. Traditionally, kubectl is primarily used in the terminal for nearly all cluster related tasks. Still, it is useful to have a visual representation of our cluster in a user-friendly interface. To install the dashboard, kubectl needs to be installed and running on the server.

Configuration management is the process by which a company or organization defines and tracks the state of its infrastructural resources. Encapsulated in those resources are both physical hardware and software. It is a means to ensure that when changes are made to a system, those changes are tracked, geared toward the ultimate predefined criteria of what state should be.

What is K3s?

K3s is a lightweight version of Kubernetes. It is a highly available Kubernetes certified distribution designed for production workloads in unattended, limited resource, remote locations, or inside an IoT appliance. The developers of K3s declare that K3s is capable of almost everything that K8s can do.

What is Puppet?

Puppet is a cross-platform client-server based application used for configuration management. It handles the software and its configurations on multiple servers. There are two versions available. One is open-source, the other is a commercial version. It works on both Linux and Windows platforms. It uses a declarative approach to automate updates, installations, and other tasks. This feature allows the software to configure those systems using files called manifests. A manifest contains the instructions for a group or type of server(s) being controlled.
