Day-1: Getting Started With DevOps World!

What is DevOps?

DevOps is a methodology in the software development and IT industry. Used as a set of practices and tools, DevOps integrates and automates the work of software development (Dev) and IT operations (Ops) as a means for improving and shortening the systems development life cycle. DevOps is complementary to agile software development several DevOps aspects came from the agile way of working.

What is Automation, Scaling, Infrastructure?

• Automation: DevOps automation is the?practice of automating?repetitive and manual DevOps tasks to be carried out without any human interaction. Automation can be applied throughout the DevOps lifecycle, spanning. The goal of DevOps automation is to streamline the DevOps lifecycle by reducing manual workload. This automation results in several key improvements. Automation relies primarily on software tools and presetting configurations to automate necessary processes and tasks.
• Scaling: Cloud scalability?in cloud computing refers to the ability to increase or decrease IT resources as needed to meet changing demand. Scalability is one of the hallmarks of the cloud and the primary driver of its exploding popularity with businesses.
• Infrastructure: Infrastructure as code uses DevOps methodology and versioning with a descriptive model to define and deploy infrastructure, such as networks, virtual machines, load balancers, and connection topologies.

Why DevOps is Important?

1. Ensure faster deployment: Faster and more frequent delivery of updates and features will not only satisfy the customers but will also help your company take a firm stand in a competitive market.
2. Stabilize work environment: Do you know that the tension involved in the release of new features and fixes or updates can topple the stability of your workspace and decreases overall productivity? Improve your work environment with a steady and well-balanced approach to operation with DevOps practice.
3. Significant improvement in product quality: Collaboration between development and operation teams and frequent capturing of user feedback leads to a significant improvement in the quality of the product.
4. Continuous delivery of software: In DevOps methodology, all of the departments are responsible for maintaining stability and offering new features. Therefore, the speed of software delivery is fast and undisturbed, unlike the traditional method.Continuous integration?and?continuous delivery?are practices that automate the software release process, from build to deploy.
5. Security: Move quickly while retaining control and preserving compliance. You can adopt a DevOps model without sacrificing security by using automated compliance policies, fine-grained controls, and configuration management techniques. For example, using infrastructure as code and?policy as code, you can define and then track compliance at scale.
