How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a DevOps with Terraform with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.
The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.
Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

Where is Terraform used?
Infra-as-Code Party Tricks
- Spinning up a herd of servers faster than a microwave popcorn during a Netflix binge.
- Playing multi-cloud hopscotch with your entire application stack, no sweat or tears involved.
- Laying out network topologies like a spider spins its web, with precision but without getting tangled.
- Version-controlling the cloud as if it's a video game save point - reload when the boss level gets too tough.
Terraform Alternatives
Pulumi
Pulumi is an infrastructure as code tool that allows developers to define and deploy cloud resources using familiar programming languages such as JavaScript, TypeScript, Python, Go, and .NET.
- Uses real programming languages.
- Supports multi-cloud configurations.
- Brings familiar test practices to IaC.
import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";
const bucket = new aws.s3.Bucket("my-bucket", {
acl: "private",
});
- Slightly steeper learning curve for IaC newbies.
- Diverges from declarative approach of Terraform.
- Tooling and editor integration might be less mature.
CloudFormation
AWS CloudFormation provides a declarative way to outline AWS infrastructure using a template made up of JSON or YAML.
- Native integration with AWS Services.
- Supports rollback of changes if deployments fail.
- Built-in drift detection.
Resources:
MyBucket:
Type: AWS::S3::Bucket
Properties:
AccessControl: Private
- AWS-specific; not suitable for multi-cloud.
- Templates can be verbose and complex.
- Less flexible compared to Terraform Modules.
Ansible
Ansible is a configuration management tool that can also be used for orchestration or as an IaC tool, focusing on automation using YAML-based playbooks.
- Agentless; manages nodes over SSH.
- Extremely simple to set up and use.
- Large, supportive community and plenty of modules.
- hosts: servers
tasks:
- name: ensure the S3 bucket exists
aws_s3:
bucket: mynewbucket
mode: create
- Less suited for complex orchestration.
- Imperative approach might lead to drift in state.
- Performance can degrade with large inventories.
Quick Facts about Terraform
Once Upon a Manual Laborland...
In the dark ages of 2014, a wizard named Mitchell Hashimoto conjured up a spell called Terraform. Yeah, you heard it right, in the IT realm, four years is akin to a century ago! Poof, and suddenly infrastructure became code. I mean, who needs wands and broomsticks when you can just write down what you want your cloud kingdom to look like and abracadabra, it's done!
Upgrading the Spellbook
With great power comes great responsibility... and a bunch of updates! Terraform didn't just stay put; it evolved faster than a rabbit population. By 2021, it had shape-shifted into version 1.0, looking all spiffy and stable, promising those who practice the arcane arts of DevOps a 'backward compatibility' charm. That's code for "We won’t break your stuff with updates," which, as you know, is quite the pledge in the software sorcery world.
The Incantation Syntax
Eloquent as Shakespeare and structured like a LEGO set, Terraform's language, HCL (HashiCorp Configuration Language), was designed to describe the end state of your infrastructure with the clarity of a tropical lagoon. It's both human and machine-friendly, so even the robots can't complain. Seek and ye shall find! Behold, the sacred script to summon an S3 bucket:
resource "aws_s3_bucket" "bella_bucket" {
bucket = "my-supercool-bucket"
acl = "private"
}

HCL (HashiCorp Configuration Language)
Picture yourself crafting a love letter, but instead of professing your undying affection, you're sweet-talking a server setup. That's HCL for you – the poetry of Terraform configuration! Intuitive as a pet following crumbs, HCL's got a JSON-compatible sheen, making your Infrastructure as Code endeavors a walk in the park. A harmonious blend of human-readable meets machine-efficient, HCL lets your infrastructure bloom like a well-watered Chia Pet.

ami = "abc123"
instance_type = "t2.micro"
}Version Control Systems (Git)
Git, the safety net for your coding high-wire act, captures every somersault of your Terraform code. Commit by commit, branch by branch, it guards against the "Whoops, shouldn't have deleted that" fiasco. Git also pairs with Terraform like peanut butter with jelly, ensuring your infrastructure recipes can be versioned, tracked, and shared – just shy of slapping a bow on it and calling it a gift.
git add .
git commit -m "Add initial Terraform config for a new VPC"
git push origin mainContinuous Integration/Continuous Deployment (CI/CD)
CI/CD platforms, like juggling while unicycling, keep the Terraform deployment balls beautifully airborne. Jenkins, GitLab CI, and GitHub Actions let you push updates without breaking a sweat or the infrastructure. Automate your Terraform plan and apply, and you can sit back, relax, and watch as your code gets deployed like clockwork-powered cupcakes on a conveyor belt!

Groove to the rhythm of your metrics and logs as these tools lay down the beat.
Container Orchestration (Kubernetes, Docker)
Kubernetes is the grand puppet master of containers, skillfully orchestrating your Docker darlings across a stage of servers. It ensures each container plays its part seamlessly, whether it's the prima donna front-end or the sturdy back-end bass. Combined with Terraform, deploying these container performances becomes as smooth as a Broadway show tune.
Configuration Management Tools (Ansible, Chef)
Imagine your infrastructure as unruly hair, and Configuration Management tools are the combs and gels bringing it to a slick pompadour. Ansible scripts are like gentle strokes, soothing your servers into uniformity. Chef, with its recipes and cookbooks, whips up a gourmet dish of automated settings. Terraform lays the canvas, and these tools paint the final polish.
Scripting Languages (Bash, Python)
Scripting languages are your Swiss Army knife in a jungle of tasks. Need to automate a chore? Bash it. Want to parse some complex output? Python it. When your Terraform deployment scripts need that extra sprinkle of logic or a dollop of decision-making, these tried and true comrades are ready to jump into the fray, torches blazing!
