Cloud and DevOps explained
Cloud computing provides on-demand infrastructure and managed services over a network. DevOps is a culture and engineering practice that improves collaboration between software development and operations through automation, feedback and shared responsibility for reliable delivery.
Core cloud concepts
Cloud platforms provide compute, storage, networking, databases, identity and monitoring. Infrastructure as a Service offers flexible virtual resources, Platform as a Service manages more of the runtime, and Software as a Service delivers finished applications. Good architecture balances reliability, security, performance and cost.
Containers and orchestration
Docker packages applications with their dependencies into portable containers. Kubernetes schedules and manages containers across machines, providing scaling, service discovery and recovery. Containers improve consistency, but teams still need sensible images, resource limits, secrets management and observability.
CI/CD and infrastructure automation
Continuous integration automatically builds and tests each change. Continuous delivery prepares verified releases, while deployment automation moves them safely into environments. Tools such as Git, Jenkins, GitHub Actions, Terraform and Ansible make changes repeatable and reviewable.
How to learn Cloud and DevOps
Build Linux and networking foundations, then practise Git, scripting, Docker and CI/CD. Add one cloud platform, infrastructure as code, Kubernetes, monitoring and security. Deploy a real application and document how it is built, released, observed and recovered.
● LEARN BY BUILDING
Turn the concept into a real project.
Practise Linux, cloud infrastructure, Docker, Kubernetes, CI/CD, automation, security and monitoring.
