What is Continuous Delivery(CD)?
Continuous delivery is a software development practice that uses automation to speed the release of new code.
It establishes a process through which a developer's changes to an application can be pushed to a code repository or container registry through automation.

Why we wants to implement CD?
Continuous deployment is basically when teams rely on a fully-automated pipeline. This practice fully eliminates any manual steps and automates the entire process. Therefore, continuous deployment ensures that code is continuously being pushed into production.

Why DevOps buzz is growing around us?
Devops-it's a software development and operations approach that enables faster development of new products and easier maintenance of existing deployments.

What is DevOps?
DevOps is a set of practices that combines software development and IT operations. It aims to shorten the systems development life cycle and provide continuous delivery with high software quality.

Top 20 Advantage of DevOps?
1: It involves multidisciplinary teams. DevOps is based on collaboration.
2: It provides agility to overall business deliveries.
3: Continuous improvement is the core.
4: DevOps is focused on goals and not on processes.
5: Continuous Integration and Delivery = Faster feature or functionality release = Faster earnings
6: Highly available applications or websites = Permanent presence/influence on the internet = More business opportunities
7: Automated IaaS = Permanent application/website capacity to attend demand = Customer confidence in your business
8: Constant monitoring on development /integration /building /testing /deploying /operation processes = Better capacity to attend to emergencies = Lower risk for losing business or customers

1. It provides Serverless approaches
2. Define and keep a full track of Key Performance Indicators
3. Microservices architecture

Why doing a DevOps in right way is difficult?

1. Resistance to change
2. Moving away from expertise teams to cross-functional teams
3. Misplaced focus on tools
4. The clash between Dev and Ops tools
5. Moving from legacy applications to microservices
6. The lack of expertise in the industry and lack of vision
7. Choice of tools
8. The optimization of the delivery pipeline
9. Managing multiple environments
10. The speed of innovation

• What is DevOps? It is combination of development and operations to increase the efficiency, speed, and security of software development.
• Top 20 Advantage of DevOps? Fast Delivery Detect errors early because continuous monitoring and testing Team collaboration Fast delivery Reduce cost Reduce time Improve quality Automation with tools Multiple test runs a day Multiple builds a day
• Why doing a DevOps in right way is difficult? As you can see there are lot of tools and technologies “to learn” for DevOps. But only learning, say for example, building/deploying a simple web application using various tools such as Maven, Jenkins, Docker and AWS is not enough. You learn these tools and methods by all the videos/user guides/tutorials available. But real-life scenarios are not that easy for sure! And that’s the challenging part. You have to apply all those tools and technologies to real-time scenarios.

Faster development.
Increases frequent releases.
Decreases manual intervention by Automating
Can focus more on code quality because of quality gates
Reliability of service because more checks and automation involved.
