Building the Future: Learn the Essentials of IaC and Platform Engineering
What is Infrastructure as Code?

Infrastructure as Code (IaC) refers to the practice of managing and provisioning IT infrastructure using code. Instead of manually configuring servers, networks, and other resources, IaC allows you to define your infrastructure in a declarative manner using scripts or configuration files more like a software project. You define your infrastructure’s configuration in code, specifying the desired state and tools like Terraform automate the provisioning and configuration process.

Think of it as writing a detailed blueprint for a construction project – precise, replicable, and adaptable. This method offers several benefits. It ensures consistency across environments, minimises human error, and facilitates easy scaling. Additionally, like software code, infrastructure code can be managed using version control systems, enabling collaboration and providing a safety net for changes.

IaC is more than just automating infrastructure deployment. It’s about embracing principles of software development to create scalable, reliable, and consistent infrastructure that can adapt to changing business needs while maintaining high levels of security and compliance.

Why is IaC important?

Consistency and Standardisation. With IaC, infrastructure is defined in code, ensuring that every environment – development, testing, production – is set up exactly the same way. This consistency reduces errors caused by manual configuration and ensures that applications behave consistently across different environments.

Automation and Efficiency. IaC automates the provisioning and configuration of infrastructure, saving time and effort. Manual tasks that used to take hours or days can now be completed in minutes or even seconds. This automation boosts efficiency and frees up resources to focus on higher-value tasks.

Scalability and Flexibility. IaC allows infrastructure to be scaled up or down easily to meet changing demands. Whether it’s adding more servers to handle increased traffic or spinning up new environments for testing, scaling infrastructure becomes a matter of modifying code rather than manually configuring each component.

Version Control and Collaboration. Infrastructure code can be version-controlled using tools like Git, enabling teams to track changes, collaborate effectively, and revert to previous states if necessary. This ensures that everyone is working on the same version of infrastructure and promotes better collaboration between development, operations, and other teams.

Reduced Risk and Increased Security. Since infrastructure changes are made through code, there’s less room for human error. Additionally, IaC allows for security best practices to be built into the code, ensuring that security policies are consistently applied across all environments.

In traditional infrastructure management, security configurations are often applied manually or through separate processes after the infrastructure is provisioned. This can lead to inconsistencies and oversights, increasing the risk of security breaches.  With IaC, security policies are defined in code, just like the infrastructure itself.

How to get started with IaC

Before diving into IaC tools and frameworks, it’s essential to understand the underlying concepts and principles. Here are some key concepts to get you started:

Declarative vs. Imperative. Understand the difference between declarative and imperative approaches to infrastructure management. Declarative IaC tools (e.g., Terraform) focus on describing the desired state of infrastructure, while imperative tools (e.g., Ansible) specify the steps needed to achieve that state.

Version Control. Familiarise yourself with version control systems like Git. Version control is crucial for managing infrastructure code, tracking changes, and collaborating with team members.

Cloud Providers. If you’re using cloud services, learn about the specific IaC tools provided by your cloud provider. For example, AWS offers AWS CloudFormation, Azure has Azure Resource Manager (ARM) templates, and Google Cloud provides Deployment Manager.

Hands-On Learning

The best way to learn IaC is by doing. Start with simple projects and gradually build up complexity as you gain confidence. Here’s a suggested learning path:

Tutorials and Documentation. Most IaC tools provide extensive documentation and tutorials. Work through these tutorials to understand the basic concepts and commands.

Hands-On Projects. Start with small projects, such as provisioning a virtual machine or setting up a simple web server. Experiment with different configurations and settings to understand how they impact your infrastructure.

Community Resources. Join online communities and forums related to IaC. Platforms like Stack Overflow, Reddit, and GitHub are great places to ask questions, share knowledge, and learn from others’ experiences.

What is Platform Engineering

Platform engineering is an innovative discipline within software development and IT operations that focuses on creating and maintaining the foundational systems and environments essential for efficient application development and deployment. It encompasses the design and implementation of scalable infrastructure, automated CI/CD pipelines, containerisation, and robust monitoring systems. By standardising these critical components and integrating security best practices, platform engineering provides a reliable, efficient, and secure foundation that enables development teams to build, test, and deploy applications with greater speed and consistency. This holistic approach not only streamlines workflows but also enhances overall system resilience and developer productivity.
