Four easy reasons why you should use Infrastructure as Code (IaC)

As we enter a new era of Cloud computing, an era of optimization and automation, the need for an easy way to configure and deploy infrastructure environments in Cloud becomes paramount. How do you accomplish this?

The simple answer to this question is Infrastructure as Code (IaC). We've touched upon the subject of IaC numerous times in previous blog posts and other content on social media, enough times that we probably sound a bit like a broken record. However, we cannot understate the importance of this concept. To give you a short recap of the principles of IaC and how it works, here's the gist of it:

  • Any Cloud environment that runs applications and other services require you to configure various components such as operating systems, networking and storage.

  • IaC allows you to configure and support your Cloud infrastructure using code instead of manually configuring all settings.

If your goal is to create a reliable, fast and easy-to-follow infrastructure (if not, feel free to stop reading), then IaC should definitely be your way forward. If you have doubts for some reason, this blog post will provide you with four easy reasons why you should use Infrastructure as Code.

Four "easy" reasons for Infrastructure as Code

Easy to deploy

Working with infrastructures can be time consuming, especially if you do it manually. The manual aspect in this case also often leads to inconsistencies and hidden errors which can complicate things down the line. With IaC you can set up and control your virtualised resources by codifying them, making the infrastructure reliably deployable in just minutes. An additional benefit to this is that this processes is highly repeatable. Say that you want to duplicate your infrastructure to run it in another region. With IaC, this region would be up and running in no time.

To make the deal even sweeter, there are a lot of great third-party solutions that you can use and improve to get you started. In fact, Altostruct has its own open-source repository of templates designed for various use cases.

Easy to comprehend

In a recent LinkedIn newsletter, we stated that creating a complex infrastructure is one of the easiest tasks in the world. The real challenge is to create something extremely simple that works. This is perhaps one of the biggest reasons for IaC: the visibility and clarity it offers. In a recent conversation regarding AWS and infrastructure, Altostruct's CEO, Erik Rehn, had this to say about hard-to-follow and complex infrastructures:

"Every infrastructure will eventually, as it scales and the user-base grows, become complex. Therefore, if your infrastructure is complex and confusing from the start, you're in for some serious problems down the line."

With Infrastructure as Code the code acts as a single source of truth for your entire infrastructure, making it easy to understand, document, and collaborate on the architecture. IaC encourages best practices in documentation, version control, and change tracking, ensuring that everyone involved has a clear understanding of the infrastructure's design and purpose. If you ever have the need to "hand" over the infrastructure to someone, having a comprehensive and flexible infrastructure will likely make this task less if a headache.

Easy to manage

IaC simplifies infrastructure management by allowing you to define infrastructure components in code and declaratively state how they should look. This declarative approach makes it easier to manage infrastructure at scale, as changes and updates can be applied consistently across all environments. as long as the developer knows which components and settings they need to run their application, it does not get easier than that.

Here's three excellent services that can help you with you IaC needs:


Easy to update

In a dynamic technology landscape, infrastructure requirements can change frequently. IaC excels in handling these changes. When you need to update your infrastructure, you can make code changes, test them in a development environment, and then apply them across staging and production with confidence. This approach eliminates the need to make manual adjustments, reducing the risk of configuration errors and ensuring that updates are applied consistently. With version control and collaboration features built into IaC tools, you can also manage updates more effectively within your team.

Some final words

Infrastructure as Code is a powerful paradigm for modern IT operations, offering numerous benefits that streamline infrastructure management and increase reliability. By automating deployment, enhancing comprehension, simplifying management, and facilitating updates, IaC empowers organizations to better adapt to the fast-paced demands of today's digital world. Whether you're a small startup or a large enterprise, embracing IaC can help you achieve greater efficiency, scalability, and agility in your infrastructure management processes. So, make the smart choice and start implementing Infrastructure as Code in your organisation today.
