![]() Specifying what to do and how to do is an imperative style. This programming paradigm expresses the logic of a computation(What to do) and describes its control flow(How to do)Īssume you are going to your office, you book a cab and start giving step by step directions to the driver until you reach the office. We will focus on Imperative and Declarative. Functional (which is considered a subset of that declarative paradigm).It implements the infrastructure as a code because policies and configurations are written as code.īefore we learn Puppet DSL, let’s understand programming paradigms:Ī programming paradigm is a style you are using in computer programming. It is also used as a deployment tool as it automatically deploys software to the system.It also provides control over all the configured system, so a centralized change gets automatically effected.If the config is changed, Puppet tool will revert to the pre-defined configuration on the host. The tool allows you to continuously monitor servers to confirm whether the required configuration exists or not and it is not altered.Puppet allows you to define distinct configurations for every host.This reduces the human effort and makes the development process fast and effective. To do this, you can use Puppet, which allows you to write a simple code which can be deployed automatically on these servers. System Admin working manually on the servers ![]() As a system admin, it’s your role to ensure that all these servers are always up to date and running with full functionality. Puppet Enterprise: Commercial version that offers features like compliance reporting, orchestration, role-based access control, GUI, API, and command-line tools for effective management of nodes.įor example, you have an infrastructure with about 100 servers.It is available directly from Puppet’s website and is licensed under the Apache 2.0 system. Open Source Puppet: It is a basic version of Puppet configuration management tool, which is also known as Open Source Puppet.Deployment models of configuration management tools.The Configuration Management tool like a Puppet was introduced to resolve such issues. ![]() However, it is a difficult job when they are working on a massive infrastructure. These professionals can automate this task, by writing scripts. System Administrators mostly perform repetitive tasks like installing servers, configuring those servers, etc. It also allows access to an accurate historical record of system state for project management and audit purposes. Before we learn Puppet, let’s understand: What is Configuration Management?Ĭonfiguration management is the process of maintaining software and computer systems (for example servers, storage, networks) in a known, desired and consistent state. ![]()
