Get your hands-on agent-less infrastructure automation:
Now many companies embark on their DevOps journeys to automate infrastructure and building blocks for strong DevOps foundation.
Real time, managing thousands of servers in an organisation is an error-prone task to operations teams, and doing tasks on that inside applications is also a next level task. In this scenario, firms started the concept of configuration management like puppet, chef, etc
These tools will help the teams to automate the server tasks in a systematic way, but the above-mentioned tools will require agent installation on client machines or servers for communication and task execution. Installing agents in thousands of servers for a small task is a hectic job again so the trend moved to agentless infrastructure automation to execute tasks in seconds.
In this, our tool of choice is Puppet – Bolt
Bolt is an agentless infrastructure automation tool that helps teams to directly execute commands or scripts on remote systems. Bolt also an open-source orchestration tool and can be implemented in multiple platforms like Linux distributions (Debian, Kali, RHEL).
Every tool in the background uses one platform to perform its functionality like this we know the most used communication ways to interact with servers. Generally, in Linux based distributions we use SSH to interact with its shell, and in windows platforms, we use remoting protocols to connect with PowerShell. Bolt enables you to move a step further.
Bolt uses SSH and WinRM protocols to communicate with the remote servers (Linux – SSH and Windows- WinRM). It establishes direct communication with the system shell and executes commands so the output rate will be faster here. so, you are not required to install any agent software.
Teams can use Bolt to keep servers up to date and pushing packages or scripts, monitoring the application & system-level services and tasks. No prior Puppet knowledge is required to perform these tasks we can directly start working on Bolt from now.
Let’s see one real-time workflow:
Suppose I have 500 servers in my home to perform various POC’s on the latest trends and am not maintaining active directory kind of thing to manage my servers centrally. Sometimes I may require applying the patch to all the servers or some at most. So, I need a centralized tool here that should be an opensource to manage my cost scale. So here I am implementing puppet bolt to manage all the devices and I can make one server among as a bolt server (local workstation) and start using it to do my task. Bolt is a scalable way to automate my workflow. To Linux servers, I will use SSH and for windows, I use WinRM as a transport protocol.
Bolt does not conflict with the Puppet version if you have installed it in any of your machines. Bolt team is working out the kinks and smoothing out the edges and making things easier to automate regular workflows. You can scale more than 1,000 concurrent connections with the bolt. Bolt supports various scripts that are written in python, bash, PowerShell, Ruby, etc. finally bolt helps companies to move faster with fewer errors and less overhead to the teams. Bolt is having well-structured official documentation to follow.
