The DevOps Essentials - The Handbook

Explore how DevOps unifies development and operations as a bottom-up cultural movement, emphasizing collaboration, continuous integration, monitoring, and deployment practices while bridging tools like Jenkins and Docker with the cloud.

DevOps unifies development and operations through collaboration and automated pipelines that build, test, and deploy software reliably and faster, with monitoring ensuring smooth releases.

DevOps unites development and operations, replacing the speed and stability tension with shared goals, enabling faster time to market, fewer production failures, and immediate recovery through common tools.

Explore DevOps history from agile to the dev-ops movement, highlighting rapid delivery through small, frequent cycles and the dev-ops collaboration that fuels automation and the tool chain.

contrast traditional silos with devops, highlighting walling and finger-pointing, then show automated builds, testing, and deployment with monitoring that delivers faster, stable releases and happier teams and customers.

Automate the build with scripts and build tools to compile, transform, and test code, delivering consistent, portable, and reliable deployable output across environments and CI servers.

Learn how continuous integration streamlines code merging with automated builds and unit tests, catching bugs early to prevent merge conflicts when multiple developers contribute.

continuous integration merges small changes with automated builds and tests on CI servers like Jenkins, CircleCI, and GitLab CI, enabling early bug detection and frequent releases.

Understand continuous deployment and continuous delivery, how automation enables frequent, small production releases, and the role of source control, build, and stage-to-prod pipelines.

Learn how continuous delivery keeps code deployable through automated build, testing, and staging, enabling frequent, small deployments that accelerate time to market and include CAB-guided production approval.

Learn how configuration management minimizes drift by automating centralized changes across servers, maintaining a standardized, reliable infrastructure, and linking deployments to infrastructure as code.

Monitor DevOps environments by collecting and visualizing metrics, logs, and network data to detect issues in real-time, present data in charts, enable rapid response, and improve stability and performance.

Learn how microservices break a monolithic application into small, loosely coupled services that communicate via stable APIs, enabling modular design, independent deployment, scalable architectures, and devops efficiency.

Explore build automation tools like Maven, Gradle, Ant, NPM, Grunt, Gulp, Make, and Packer. Learn how continuous integration triggers automated builds with Jenkins, Travis CI, Bamboo, and source control integration.

Learn how configuration management uses infrastructure as code and declarative configuration to automate and maintain systems with tools like Ansible, Puppet, Chef, and Salt.

Explore virtualization and containerization tools, including hypervisors and Docker, to understand lightweight containers, portability, and the role of orchestration in DevOps.

Evaluate infrastructure monitoring and application performance monitoring using tools like Sensu, Nagios, New Relic, and AppDynamics, and leverage Elastic Stack and Kibana for aggregation and analytics.

Explore how automation and orchestration provision and scale resources, enable auto-scaling and self-healing, and integrate tools like Docker Swarm, Kubernetes, ZooKeeper, Terraform, and Ansible.

Explore how devops practices and culture integrate with cloud architectures from iaas and paas to saas and serverless, highlighting collaboration and the tools that enable cloud led devops.
