What are Automation, Scaling, and Infrastructure
In DevOps automation means automating repetitive tasks in DevOps like build and deployment processes, infrastructure provisioning and configuration, testing and monitoring. Automation helps improve speed, reliability and consistency in software development. some examples of automation tools are:- Jenkins, Gitlab etc.
Scaling in DevOps means the ability to scale applications both horizontally and vertically, here horizontal scaling means increasing the number of servers or instances and vertical scaling means increasing the resources of existing instances like RAM, CPU etc. Some common examples are Kubernetes, Load balancers, and serverless computing platforms.
Infrastructure means underlying technology resources and components necessary to support and run software applications. Infrastructure includes servers(virtual or physical), Networking equipment, Operating systems, storage devices etc. Infrastructure can be provisioned and managed by Infrastructure as a code(ie. terraform), Configuration management tool (ie. ansible), and Cloud platforms like AWS, GCP and Azure.
Why DevOps is important?
DevOps is important because it helps us in many ways like maximizing efficiency, Optimizing the entire business, improving the speed and stability of software development and deployment etc.
