How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a Full Stack Web with DevOps 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 DevOps used?
1. Rapid Bug Squashing Adventures
- Gone are the ages of 'buggy' sagas dragging on forever! DevOps swoops in like a superhero, wielding automated pipelines to zap defects faster than a coder can yell "Oops!"
2. Feature Fiesta with Continuous Deployment
- Imagine throwing a non-stop party where software updates are the guests of honor. That's DevOps for you, ensuring the feature fest never ends, with updates smoothly salsa dancing to production.
3. Knightly Ops and Developer Roundtable
- With DevOps, ops folks and devs sit at a roundtable, not in castles far apart. They break bread (and silos) to unify workflows, slay downtime dragons, and toast to resilience.
4. Cloud Conquest
- In this epic quest, DevOps is the trusty steed that carries teams to the cloud castles in the sky. Its magic spells of orchestration conquer sprawling server empires without breaking a sweat.
DevOps Alternatives
Agile Methodology
Agile is an iterative approach to project management and software development that emphasizes flexibility, collaboration, and customer satisfaction. By breaking projects into small pieces, Agile helps teams deliver value faster.
// No direct code sample for Agile as it's a methodology not a scripting language.
- Responds well to change
- Improves product quality
- Enhances customer satisfaction
- Requires cultural shift
- Difficult to scale
- Planning can be less predictable
Waterfall Model
The Waterfall model is a linear and sequential approach to software development with distinct goals for each phase of development. Once a phase is completed, you cannot go back.
// Waterfall is not expressed in code, but in phases such as:
1. Requirements
2. Design
3. Implementation
4. Verification
5. Maintenance
- Simple and easy to understand
- Well-organized structure
- Works well for smaller projects
- Not suitable for complex projects
- No working software until late
- Difficult to accommodate changes
Scaled Agile Framework (SAFe)
SAFe provides a guide to scaling Agile and Lean practices beyond single teams. It helps larger organizations coordinate, plan, and deliver software.
// SAFe is a set of workflow patterns intended to guide enterprises in scaling lean and agile practices
// Again, not a coding practice, so no code sample.
- Facilitates large team coordination
- Aligns with enterprise goals
- Structured guidance for scaling
- Complex for small teams
- Can be rigid and prescriptive
- Implementation can be costly
Quick Facts about DevOps
DevOps: A Sibling Squabble Turned Family Business
Picture it: Agile had a baby with IT operations. They named it DevOps. Born in 2009, this brainchild of Patrick Debois disrupted the tech world harder than a toddler in a china shop. Poised to mend the eternal feud between coders cranking out features and sysadmins hungry for stability, it was like teaching cats and dogs to tango. Groovy, right?
Continuous Everything - Not Just For Buffets
With DevOps came a buffet of 'continuous' options: integration, delivery, deployment, you name it. The software world gaped as traditions were tossed aside faster than leftovers at a high-stakes poker game. Suddenly, code whizzed from concept to customer quicker than greased lightning, shattering the slow dance of yesteryear's release cycles.
The Automation Jamboree
Ever heard of an assembly line for code? Well, DevOps threw a game night and invited automation tools to play. This wasn't just a tea party; it was a full-blown jamboree where scripts and tools like Jenkins, Puppet, and Ansible became the life of the party. "Automate or perish!" became the industry's party chant.
# Party like a DevOps star - automate deployment using Jenkins!
pipeline {
agent any
stages {
stage('Build') {
steps {
echo 'Building..'
// Building code goes here
}
}
stage('Test') {
steps {
echo 'Testing..'
// Testing code goes here
}
}
stage('Deploy') {
steps {
echo 'Deploying..'
// Deployment magic happens here
}
}
}
}

Git & Version Control Systems
Imagine a world where your code never gets lost, like socks in a laundry. That’s what Git does for developers. It's the magical undo button we all wish we had for life. Just don't push the wrong button or you'll end up with the 'master' disaster.
git commit -m "Added awesome feature"
git push origin masterContainerization with Docker
Containers are like Tupperware for code; they keep it fresh and stop it from interfering with other code. Docker is your kitchen where you can cook up any app environment without burning down the house - unless you forget your ports, then everything's on fire.
docker build -t my-cool-app .
docker run -d -p 80:80 my-cool-appKubernetes
So you've got a boatload of containers and you need an octopus to juggle them? Enter Kubernetes, the container orchestrator that's harder to spell than to use. It's like a game of real-time strategy with your apps, where you're deftly commanding your peons – I mean pods.
kubectl get pods
kubectl deploy my-super-appContinuous Integration/Continuous Deployment (CI/CD)
Ever wished you could clone yourself to do more work? CI/CD is the next best thing for your code. Tools like Jenkins, GitLab CI, and GitHub Actions help automagically test and deploy your code like a conveyor belt sushi restaurant – but for software releases.
pipeline {
agent any
stages {
stage('Build') {
steps {
sh 'make'
}
}
}
}Infrastructure as Code (IaC)
Remember playing with LEGO? Terraform and Ansible let you build server infrastructure by snapping blocks of code together instead of physical bricks – and no foot injuries when stepping on them! Configure and version your cloud environment as if it's Minecraft.
resource "aws_instance" "my_instance" {
ami = "ami-0c55b159cbfafe1f0"
instance_type = "t2.micro"
}Monitoring and Logging
Ever feel like Big Brother watching your systems? That's Prometheus and Grafana in the DevOps world. They keep tabs on your apps, ensuring they're behaving. And if they're not, you'll know about it faster than a gossip in a small town.
metrics_path: '/metrics'
static_configs:
- targets: ['localhost:9090']Cloud Service Providers
If your app's server was a house, the cloud would be a colossal apartment complex that you rent space in. Providers like AWS, Azure, and Google Cloud offer a rooftop infinity pool experience for your apps with scalability options as expansive as the city skyline.
aws s3 cp myapp.zip s3://my-deployment-bucket/
Configuration Management
Imagine a world where your configurations are like well-trained pets. Meet Chef, Puppet, and SaltStack, which are like the digital whisperers that keep your server configurations in line - so you don't come home to a chewed-up infrastructure.
package 'nginx'
service 'nginx' do
action [:enable, :start]
endScripting Languages
Scripts are the Swiss Army knives in a DevOps professional’s belt. Learning languages like Python, Bash, and Ruby is like unlocking wizard spells; you'll automate tasks and conjure up scripts, charming servers to do your bidding.
#!/bin/bash
echo "Hello, magical world of automation!"Security Best Practices
It’s a digital Wild West, and security is your six-shooter. Understanding principles like the OWASP Top 10 is as important as knowing the difference between a click and a bang. Keep your apps locked up tighter than an ancient treasure.
