What is SaltStack?
SaltStack is an open-source infrastructure management platform built on a dynamic communications bus. The main structure of SaltStack contains two main components for work: one Salt Master and several Salt Minions. Salt Master is the main control system used to send commands to Salt Minion and their configuration. Salt Minions (they are also called Nodes) are subsystems that work on managed servers and receive commands from the master, as well as their configuration. At least two servers are required for interaction settings. One for the Master and one for the node. All nodes are configured in the same way.

Introduction
Configuring a single server with the required software is a reasonably simple task. However, if numerous servers need to have the same or similar software and configurations installed on them, the process would use numerous man-hours to complete, which would deplete your already strained resources. Without some form of automation, this task can become nearly insurmountable. With this task in mind, new configuration management tools were developed to address the need to deploy new servers with premade configurations and updates, that allowed for a smoother and more manageable automation process. To keep these servers syncing and to manage updates across a broad swath of hosts in a data center or cloud environment, automation tools like Puppet, SaltStack, Chef, and Ansible meet this need.

Service Mesh Defined: A Simple Overview
What is a Service Mesh?
A service mesh is a layer of communication and control between applications or microservices and the network stack they typically communicate over. This layer controls communication and helps microservices share data. This service-to-service interaction is governed by logic built into the service mesh layer. Simply put, microservices are small or partial applications, or individual functions, and the network stack is the physical networking layer.
