Infrastructure as Code (IaC) is rapidly becoming the backbone of modern IT operations. According to a recent study, over 75% of enterprises now use some form of automation for provisioning infrastructure, demonstrating how quickly infrastructure as code is reshaping IT teams. In this blog, we explore infrastructure as code, often abbreviated “infrastructure as code(IaC),” along with the variant term “infra as a code,” guiding readers from expert coders to freshers, and even those with no coding background. We'll also examine iac infrastructure as code tools, especially Terraform infrastructure as code and Azure infrastructure as code, while clarifying What is Kubernetes vs Terraform? and answering the pressing question: Is infrastructure as code dead?
What
Is Infrastructure as Code?
At its core, infrastructure as
code means managing and provisioning computing infrastructure, servers,
networks, load balancers, and more, through machine-readable definition files,
rather than manual setup or configuration tools. Essentially, infra as a code
replaces manual steps with scripts and configuration files.
The term infrastructure as
code(IaC) emphasizes that these definitions are versioned, testable, and
reproducible. And yes, even non‑coders can contribute once the templates are
pre-defined, as they don’t necessarily need to write raw code.
Who
Is This Guide For?
a)
Expert Coders
If you're an expert developer, iac
infrastructure as code is your chance to apply software engineering
patterns to infrastructure. Use infrastructure as code tools like
Terraform or Azure Resource Manager (ARM) templates. With strong programming
practices, modular design, testing, version control, you’ll find IaC fits
naturally into CI/CD pipelines.
b)
Freshers / Beginners
New to IT? Scripts and templates may
look intimidating at first, but with tools like Terraform infrastructure as
code and step-by-step guidance, you can quickly spin up servers or networks.
Concepts like declarative syntax and parameterized templates turn
repetitive tasks into reusable workflows without much coding knowledge.
c)
No‑Coders and Business Users
Surprisingly, infra as a code
is not just for developers. With visual tools or template libraries, people
unfamiliar with coding can still deploy environments. For instance, a project
manager might use a pre-written ARM template or Terraform script, customize
blueprints via friendly interfaces, and hit “apply.” However, deeper
customization still needs some understanding, so iac tools empower non‑coders
to some extent, but total lift-off still benefits from guidance.
Why
Use Infrastructure as Code?
a)
Consistency and Repeatability
IaC ensures environments are
identical: dev, staging, production. No “it works on my machine” problems when
infra as a code is correctly tracked under version control.
b)
Speed and Scalability
Provision entire clusters in
minutes. Terraform infrastructure as code can spin up dozens of servers across
providers with a single command. At scale, this saves hours of manual work and
drastically reduces human error.
c)
Auditable, Version-Controlled Infrastructure
Every change is logged. You can roll
back if something breaks. With infrastructure as code(IaC) definitions
versioned in Git, you get traceability that manual infrastructure lacks.
d)
Cost Management
Automated provisioning fosters
ephemeral infrastructure: spin-up for testing, destroy afterward. This reduces
cloud spend. For example, using Azure infrastructure as code scripts, teams saw
a 30% reduction in idle resource costs.
Real‑Life
Use Cases & Scenarios
Let’s break down a few real-world
scenarios where infrastructure as code is essential:
- Scenario A: Startup Launching Quickly
A small startup wants to launch an app. They use Terraform infrastructure as code to define their AWS VPC, EC2 instances, RDS database, and DNS records, all in under 10 minutes. This infra as a code approach gave them a mobile app back-end prototype in a day. - Scenario B: Dev/Staging Parity
A mid-sized company uses iac infrastructure as code to maintain identical environments. Developers, QA, and production all have the same configuration. Result: a 45% drop in environment-specific bugs. - Scenario C: Disaster Recovery
A financial institution maintains its infrastructure definitions with infrastructure as code(IaC). If their data center goes down, they can deploy equivalent infrastructure in another region within an hour, due to pre-defined templates. - Scenario D: Cloud‑Cost Governance
Using Azure infrastructure as code deployment, a large enterprise can deploy ephemeral test environments, then tear them down automatically. This has saved them tens of thousands in monthly Azure spend.
All these scenarios show how infra
as a code transforms operations, whether done by expert coders or fresher
team members.
IaC
Tools: What’s Out There?
A strong ecosystem of iac
infrastructure as code tools has emerged:
- Terraform infrastructure as code – A multi-cloud, open-source tool using declarative
configuration. Popular for its consistent syntax across providers.
- Azure Resource Manager (ARM) – Native Azure infrastructure as code.
- AWS CloudFormation
– Native AWS IaC tool.
- Chef / Puppet / Ansible – Configuration management tools that also support
infrastructure automation.
- Pulumi,
Google Deployment Manager – Other modern IaC solutions.
Here’s a quick breakdown:

These infrastructure as code
tools each suit different scenarios, Terraform infrastructure as code for
cross-cloud consistency, Azure infrastructure as code for deep Azure workflows,
etc.
What
Is Kubernetes vs Terraform?
- Terraform infrastructure as code is an infrastructure provisioning tool. It
declares what infrastructure you want, networks, VMs, clusters, and
Terraforms builds them.
- Kubernetes
is a container orchestration system. Once you have infrastructure
(e.g., VMs, load balancers), you deploy containerized apps using
Kubernetes.
In short:
- Terraform handles the infrastructure layer
(infrastructure as code).
- Kubernetes handles the deployment and scaling of
containers on that infrastructure.
Use them together: provision with
Terraform, then deploy containers via Kubernetes. They are complementary, not
competing.
Is
Infrastructure as Code Dead?
Absolutely not. Here's why:
- Cloud adoption continues to grow worldwide, cloud
providers like AWS, Azure, and GCP require infrastructure automation at
scale.
- The DevOps movement relies heavily on automation,
reproducibility, and CI/CD, all powered by IaC.
- New IaC tools like Pulumi, Crossplane, and serverless
frameworks continue to appear and evolve, indicating strong investment and
interest.
Infrastructure as code is very much
alive and thriving. In fact, infrastructure as code(IaC) is evolving to include
policy-as-code, GitOps, and declarative drift detection,
extending its reach well beyond basic provisioning.
