What is DevOps

DevOps is a set of cultural practices, automation tools, and collaborative ways of working that unify software development (Dev) and IT operations (Ops) into a continuous workflow. It replaces the traditional model of developers building features and throwing them to a separate ops team, creating shared ownership of the full software lifecycle through automated workflows and fast feedback loops.

What is DevOps?

DevOps stands for Development (coding, building, testing) and Operations (deployment, infrastructure, maintenance, stability). It emerged because Agile practices made developers faster, but operations struggled to keep pace. As a result, code sat in staging for days. Friday deployments became firefights. Silos between development teams building software and operations teams running it in production led to slow handoffs, blame cultures, and unowned incidents.

These silos are eliminated with DevOps. It brings development and operations together to work as one team with shared tools, shared accountability, and a shared goal: delivering working software to users as quickly and safely as possible. Five core principles govern DevOps:

How does DevOps work?

DevOps combines a set of practices (CI/CD, version control, infrastructure as code, configuration management, and monitoring) into a framework that helps teams plan, build, test, and deliver software in continuous cycles rather than big-bang releases.

The DevOps lifecycle is often visualised as an infinity loop (∞), with eight continuous phases that feed into each other.

‍Plan defines what to build and when. This is the roadmap that keeps the team aligned before anyone writes a line of code.

Code is where developers write application code using version control systems to track changes. Multiple developers can work on different features simultaneously without overwriting each other's work.

Build compiles source code, bundles dependencies, and packages the application into deployable artifacts. Build automation makes sure that what works on a developer's laptop works identically in production.

Test validates that code works correctly and meets security standards through automated unit tests, integration tests, security scans, and code quality analysis.

Release prepares validated builds for deployment through release gates, artifact promotion, and orchestration steps.

Deploy pushes code changes to production. Modern deployments happen continuously using strategies like blue-green deployments and canary releases that gradually shift traffic to new versions.

Operate maintains running applications and infrastructure, including server configurations, access controls, security policies, and automated guardrails.

Monitor tracks application performance, infrastructure health, and user behaviour in production. Monitoring data flows back into planning, creating continuous improvement loops.

Why DevOps matters for mobile development

Compared to web teams, mobile teams face unique challenges that make DevOps practices both more important and harder to get right.

Code signing adds a layer of complexity

Code signing is something web teams never deal with either. Every iOS and Android build needs valid certificates and provisioning profiles before it can run on a real device or reach the app store. Managing these credentials across a team, especially in CI, is one of the most common causes of broken builds and missed launch windows.

You can't deploy on your own schedule

Web teams push to production whenever they want. Mobile teams submit to Apple and Google's review processes, which can take hours or days. Your release management workflow needs to account for review times, staged rollouts, and the fact that you can't hotfix a live app the way you can a web app.

Testing needs real devices

Simulators catch some issues, but differences in hardware, OS versions, and manufacturer customisations mean you need real device testing in your workflow. The fragmentation across Android alone (thousands of device and OS combinations) makes this a serious engineering challenge.

Build times are longer

Compiling native iOS and Android apps takes longer than bundling a web app. Without build caching and parallelisation, CI workflows become a bottleneck that slows the entire team.

The core DevOps principles (automation, collaboration, continuous improvement) all apply to mobile. Mobile-specific constraints, however, must also be accounted for in tooling and workflows, which is why generic DevOps platforms often fall short.

DevOps best practices

These are the proven methodologies that high-performing teams use to ship software faster and more reliably.

If you do it twice, automate it

If a task is manual and you've done it more than once, automate it. Start with builds and tests (CI), then extend to deployments (CD), infrastructure provisioning (IaC), and environment setup. Automation removes human error and frees your team to focus on work that relies on critical insight and decision making.

Implement infrastructure as code from day one

Manage all infrastructure through version-controlled code files. Tools like Terraform, Ansible, and Pulumi let you spin up identical environments on demand, track every change, and roll back mistakes. Never configure a server manually in production.

Measure with DORA metrics

Track the four DORA metrics: deployment frequency, lead time for changes, change failure rate, and mean time to recovery. These are the industry-standard measures of DevOps performance, validated by years of research. They give you an objective baseline and show whether your improvements are working.

Shift security left

Integrate security scanning into your CI/CD workflow rather than leaving it as a gate at the end. Run static analysis, dependency vulnerability checks, and secret detection on every commit. This catches issues when they're easy and affordable to fix.

Use feature flags for progressive rollouts

Decouple deployment from release. Ship code to production behind feature flags, then gradually enable features for increasing percentages of users. This limits the blast radius of any issues and lets you gather real user feedback before full rollout.

Establish blameless post-mortems

When incidents happen, focus on the system failures that created the problem, not the person who triggered it. Blame cultures drive problems underground.

DevOps vs CI/CD

DevOps is the cultural philosophy and organisational strategy; CI/CD is the technical automation engine that makes DevOps practices possible.

‍

CI/CD is the engine that converts DevOps culture into measurable results. Without CI/CD automation, DevOps principles remain theoretical: teams may want to collaborate and ship faster, but manual builds and deployments create the same bottlenecks. For a deeper look at each side, see our guides to continuous integration and continuous delivery.

‍DevOps vs Agile

Agile and DevOps are complementary. Agile focuses on what to build and how to organise the work. DevOps focuses on how to deliver it reliably and continuously.

‍

Both Agile and DevOps complement each other. Agile focuses on what to build and how to organise the work. DevOps focuses on how to deliver it effectively and reliably.

DevOps vs DevSecOps

DevSecOps extends DevOps by integrating security as a first-class priority throughout the entire development lifecycle, rather than treating it as a gate at the end.

‍

The same automation and fast feedback loops that help you ship quickly also power security checks at every stage of development. Instead of catching vulnerabilities late (or not at all), you address them as they come up, building a stronger security posture without slowing down delivery.

How Bitrise handles DevOps

Bitrise is a purpose-built DevOps platform for mobile teams. Where traditional DevOps platforms treat iOS and Android as afterthoughts, often forcing you to script custom solutions for code signing, device testing, and app store deployment, Bitrise provides native mobile workflows that work out of the box.

The Workflow Editor is where you define your DevOps workflow visually or in YAML. Each workflow is a sequence of Steps (400+ pre-built integrations at bitrise.io/integrations) that handle everything from cloning your repo to deploying to the App Store. You can chain workflows together, run them in parallel, and trigger them automatically on code push, pull request, or tag.

Automated code signing removes one of the biggest friction points in mobile DevOps. Instead of manually managing certificates and provisioning profiles across your team, Bitrise handles code signing for both iOS and Android as part of the workflow. Upload your signing assets once, and every build uses the right credentials automatically.

Real device testing is built into the platform. You can run your test suites on real iOS and Android devices in the cloud, not just simulators, catching device-specific issues before they reach users.

Bitrise Release Management extends your DevOps workflow beyond CI/CD into release management. You can manage staged rollouts, track release status across both app stores, and roll back if something goes wrong, all from one dashboard.

Bitrise Insights gives you visibility into your DevOps performance with built-in analytics. Track build times, test success rates, and workflow reliability over time. Use DORA metrics to measure your DevOps maturity and identify where your workflows need attention.

Mobile teams using Bitrise ship faster because the platform handles the hard parts natively: no custom scripts, no stitching together web-focused tools that weren't built for mobile.
