AUTOMATING WITH ANSIBLE (CONFIGURATION TOOL)
Published: 2023-07-28 18:55:54

## Introduction

In the rapidly evolving world of IT infrastructure management, efficiency, scalability, and automation have become critical factors for organizations to stay competitive. Traditional manual processes for provisioning and managing servers, particularly in the context of multiple database servers and enterprise databases, are not only time-consuming but also error-prone, leading to potential downtimes and security risks. This is where ansible comes in, it's an open source automation tool which solves the aforementioned issues.

Ansible simplifies and streamlines the process of managing complex IT environments by providing a robust, agentless, and declarative approach to configuration management, application deployment, and task automation. It has gained widespread popularity among system administrators, developers, and DevOps teams for its ability to orchestrate and automate repetitive tasks, such as server provisioning and database deployment, across a wide range of platforms.

## Perks of utilizing ansible.

**1. Simplified Automation:** Ansible allows it users to define infrastructure as code using a simple, human-readable language known as YAML. This approach makes automation more accessible to both developers and system administrators, enabling them to easily describe the desired state of their database servers and manage them efficiently. You simply just write code for what should have been manually "ssh-ing" into 10-100 of servers manually and configuring them.

**2. Agentless Architecture:** Unlike many other automation tools, Ansible follows an agentless architecture, which means it doesn't require any additional software to be installed on the target servers. This minimizes the management overhead and security concerns associated with agents and simplifies the setup process for database servers.

**3. Idempotent Execution:** Ansible executes tasks in an idempotent manner, ensuring that the same configuration is applied consistently, regardless of the server's current state. This feature eliminates configuration drift and ensures that databases are provisioned consistently across the entire infrastructure. But you might be wondering isn't that too rigid? well, ansible also offers you the flexibility of applying specific changes to specific servers, based on different criterias which may include server roles(web server, file server, workstations, etc..), underlying operating system(centOS, ubuntu, windows, etc..) , conditions (updated, changed, present, etc..), etc...

**4. Reusability and Modularity:** Ansible promotes the use of roles and playbooks, which are reusable and modular components that encapsulate specific configurations and tasks. This allows teams to standardize the provisioning process, share best practices, and enhance collaboration across different projects.

**5. Integration with Existing Tools:** Ansible integrates seamlessly with various configuration management tools, cloud providers, and other DevOps technologies. This adaptability enables organizations to leverage their existing investments and incorporate Ansible into their existing workflows.

**6. Scalability and Flexibility:** Whether you need to provision a handful of database servers or manage a large-scale enterprise database environment, Ansible can scale to meet your needs. Its agentless nature and parallel execution capabilities make it well-suited for handling distributed and complex infrastructures.

**7. Community and Ecosystem:** Ansible boasts a vibrant and active community that continuously contributes to the development of modules and playbooks. This extensive ecosystem provides access to pre-built automation solutions for various databases, making it easier for teams to get started and accelerate their automation efforts.

## Conclusion

By just pressing the "Enter" key you can deploy applications on hundreds to thousands of servers within seconds to minutes with guaranteed consistency across these servers. As said earlier provisioning infrastructures just by writing code (IAC - Infrastructure As Code) has made deployment automation easier, faster, and scalable. In the coming article we'll see how to install ansible and using it at the bearest minimum.
