What is DevOps?
DevOps is a way of working that tightly integrates software development (Dev) and IT operations (Ops) to ship software more often, faster and more reliably. At its core are automation, short feedback loops and shared ownership of the running system — from the first line of code to operation in the cloud.
Also known as: DevSecOps · continuous delivery · dev and ops · Azure DevOps
Where DevOps is used
DevOps addresses a classic problem: development wants to ship new features quickly, operations wants stability — and friction and manual handovers arise between the two. DevOps resolves this by automating build, test, delivery and operation as far as possible and casting them into a continuous pipeline.
Technically, DevOps is not a single tool but an interplay of practices: CI/CD for automated building and shipping, infrastructure as code for reproducible environments, monitoring for fast feedback and a culture of shared ownership. In the Microsoft world, Azure DevOps (or GitHub Actions) forms the backbone of these workflows.
A practical example
A new SaaS platform is meant to go live within a few weeks. Instead of setting up servers manually and deploying releases by hand, the entire Azure environment is defined as infrastructure as code and rolled out automatically through DevOps pipelines. Every code change runs through automated tests and is delivered in a controlled way to test and production environments — traceable, repeatable and free of manual error sources.
Benefits & typical use cases
DevOps pays off wherever software has to be developed continuously and operated reliably — especially for cloud and SaaS solutions.
- Faster, more predictable releases through automated pipelines
- Fewer errors thanks to reproducible environments instead of manual configuration
- Fast feedback via monitoring and automated tests
- Clear traceability of who shipped what and when
How it differs from related terms
DevOps is the overarching approach; CI/CD and infrastructure as code (IaC) are concrete building blocks within it. „Azure DevOps“, in turn, is a product name for a tooling platform and should not be equated with the DevOps concept. When security is integrated into the pipeline from the start, the term is DevSecOps.
How smiit works with it
smiit applies DevOps practices consistently in cloud projects. For Claimity AG, a SaaS platform was taken live on Azure in just six weeks — made possible by infrastructure fully described as infrastructure as code and automated DevOps pipelines. This keeps environments reproducible, releases traceable and operation stable from day one.
Common mistakes & misconceptions
- DevOps is often misunderstood as just a tool chain (pipelines, containers) — in reality it is primarily a cultural and organizational practice that brings development and operations closer together.
- Many believe DevOps means creating a dedicated DevOps team; this often creates a new silo instead of improving collaboration between existing teams.
- People assume DevOps is only about speed; without automated testing and quality assurance, faster deployments simply produce faster failures.
Frequently asked questions
Is DevOps only for large tech companies?
No. In SMEs in particular, DevOps practices help small teams ship software reliably without falling back into manual routines and errors. Adoption can be gradual, for example starting with a first CI/CD pipeline.
Do we need a dedicated DevOps team for it?
Not necessarily. DevOps is primarily a way of working, not a staffing plan. Often it is enough to integrate existing development and operations tasks more closely and set up the right automation.
How does DevOps relate to security?
Closely. When security is integrated into the pipeline early — for instance through automated checks and properly managed secrets — the term is DevSecOps. This prevents security from being bolted on only at the end.
How do DevOps and Agile differ?
Agile mainly describes how requirements and development are organized — in short, iterative cycles. DevOps operates one level deeper and ensures that the resulting software is also delivered automatically and operated reliably. The two complement each other but solve different problems.
How do you start adopting DevOps?
Usually with the biggest manual pain point, often building and shipping software via a first CI/CD pipeline. From there, further practices such as infrastructure as code and monitoring can be added step by step instead of changing everything at once.
