What is DevOps?
Basically, DevOps means working with development and operations together. Let’s say a developer has written a code. Is it scalable? Well tested? Deployed in the cloud?
All these things will be made sure by the DevOps engineer. DevOps engineer uses several tools to test some of those and its uses were.
Linux: code
is an operating system. 91% of applications on the internet are using Linux. So as DevOps engineers, we need to deploy or troubleshoot on a Linux-based machine.
GIT/GITHUB: Deploy
Every developer writes code that needs to be deployed somewhere. GIT/GitHub is a platform that allows us to manage code, collaboration, and version control system
Docker: Build
can build applications in a virtual environment and ship them to any environment or Operating system.
Jenkins: Continuous integration
As soon as a developer write the code and kept in GIT/GitHub then the continuous integration will start. The code is pulled and built using Docker and tested. once tested it is ready for integration(Continuous integration) and the code needs to be deployed(continuous deployment).
Kubernetes: Container orchestration
Most demand tool in DevOps. The tool which is responsible for all the containers and needs to be handled to make everything stable.
Aws: Cloud services
To use all the tools in the virtual experience.
Infrastructure as a code: Terraform & Ansible
is the managing & provisioning of infrastructure through code instead of through manual processes. Ansible is used to update multiple servers all at once
Garafana & Prometheus: Monitoring
Used to monitor the CI/CD applications
Why DevOps and why is it important?
The simple answer would be because it’s trending. But every company has applications that need to scale up and are well tested, has to be deployed on the servers, all should be done with the latest technologies, making it higher demand.
What are Automation, Scaling, and Infrastructure in Devops?
Automation, Scaling, and Infrastructure are key components of DevOps that help to ensure the efficiency and reliability of software development and deployment processes.
Automation: In DevOps, automation refers to the use of tools and scripts to automate various tasks in the software development process. Automation helps to reduce manual errors and inconsistencies and ensures that the software is built, tested, and deployed in a consistent and repeatable way. Examples of tasks that can be automated include building processes, testing, deployment, and monitoring.
Scaling: Scaling in DevOps refers to the ability to handle increased demands on software and infrastructure as the user base grows. This can involve scaling up the hardware infrastructure or deploying additional software resources to handle the increased load. Scaling is essential for ensuring that software remains performant and available, even as usage increases.
Infrastructure: In DevOps, infrastructure refers to the underlying hardware and software resources needed to support the software development and deployment process. This can include servers, storage systems, networking components, and cloud services. The infrastructure needs to be scalable, secure, and reliable to support the needs of the software and its users.
Overall, Automation, Scaling, and Infrastructure are essential components of DevOps that help to ensure that software development and deployment processes are efficient, reliable, and scalable. By focusing on these areas, DevOps teams can reduce errors, increase productivity, and deliver high-quality software faster.
