What is Cloud Computing?

Cloud computing is offered in three different service models which each satisfy a unique set of business requirements. These three models are known as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).

There are three main service models of cloud computing – Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).

At the other end of your internet connection where you store your files and can be accessed from anywhere in the world. This could be a big deal for you, primarily because of three reasons:

• You do not have to maintain or administer any infrastructure for the same.
• It will never run out of capacity, since it is virtually infinite.
• You can access your cloud based applications from anywhere, you just need a device which can connect to the internet.

In simple terms, DevOps is about removing the barriers between traditionally s teams, development and operations. Under a DevOps model, development and operations teams work together across the entire software application life cycle, from development and test through deployment to operations.

• Public Cloud
• Private Cloud
• Hybrid Cloud

Advantages does Cloud Computing serve:

• Fast Implementation
• Instant Scalability
• Access Anywhere
• No Upfront Costs
• Maintenance Free
• Better Security

Git is a DevOps tool used for source code management. It is a free and open-source version control system used to handle small to very large projects capably. Git is used to tracking changes in the source code, enabling multiple developers to work together on non-linear development. Linus Torvalds created Git in 2005 for the development of the Linux kernel.

Git is a version control system used for tracking changes in computer files. It is generally used for source code management in software development.

• Git is used to following changes in the source code
• The spread version control tool is used for source code management
• It allows multiple developers to work together
• It supports non-linear advance through its thousands of corresponding branches

Features of Git:

• Tracks history
• Free and open source
• Supports non-linear development
• Creates backups
• Scalable
• Supports collaboration
• Branching is easier
• Distributed development

The Git workflow is divided into three states:

• Functioning directory – Adjust files in your working directory
• Presentation area (Table) – Stage the files and add snapshots of them to your staging area
• Git directory (Source) – Perform a commit that stores the snapshots permanently to your Git directory. Checkout any existent version, make changes, stage them and commit.

Continuous Testing:

The Continuous Solution Testing in DevOps is a software testing type that involves testing the software at every stage of the software development life cycle. The goal of constant testing is evaluating the quality of software at every step of the nonstop delivery process by testing early and testing them.

The Continuous Testing process in DevOps involves stakeholders like Developer, DevOps, QA and operational system.

Selenium is a transportable open source software-testing framework for web applications. It has the capability to activate on almost every operating system. A Continuous Integration Tool. A basic continuous integration tool allows the team to integrate new code that has been deposited into a central repository to produce a new build of a software solution.
