Why DevOps is so important?
I have taken up the #90DaysDevOps Challenge, and today marks the first day of this incredible learning journey. Over the next three months, I will be dedicating myself to mastering DevOps and sharing my daily learnings with all of you.
I am excited to share my daily learnings from this DevOps journey with all of you. Each day, I will post about a specific topic and concepts.
What is DevOps?
DevOps is a combination of the two words “development” and “operations.” It is a collaboration between Development and IT Operations to make software production and Deployment in an automated & repeatable way. DevOps helps increase the organization’s speed to deliver software applications and services.
LifeCycle of DevOps:
DevOps lifecycle is a series of automated development processes or workflows within an iterative development lifecycle. It follows a continuous approach, hence its lifecycle is symbolized in the form of an infinity loop. The left part deals with software development and testing. And in contrast, the right side of the infinity loop represents the deployment and operations cycle.
Plan: This is the first stage, teams identify the business requirement and collect end-user feedback. They create a project roadmap to maximize the business value and deliver the desired product during this stage.
Code: In this stage, The developers use some tools and plugins like Git to streamline the development process, which helps them avoid security flaws and lousy coding practices.
Build: Build automates the process of building executable applications from source code. The process includes linking and packaging the code into an executable form .where the basic version of the product is built using a suitable programming language such as Gradle, Maven, and Ant.
Test: In this phase, where the developed software is continuously tested for bugs. For constant testing tools used such as selenium, Junit, etc.
Release: This step involves planning, scheduling, and controlling the built process in a different environment.
Deploy: The code is deployed to the production servers. the new code is deployed continuously and configuration tools play an essential role in executing tasks. tools that are used here are Ansible, puppet, and Chef.
Operate: All operations are based on continuity with complete automation of the release process and allow the organization to accelerate the overall time to market.
Monitor: In this stage, the delivered products or application to a user has been monitored to note any uptime and downtime failures or errors.
Automation
Automation is one of the most important DevOps practices because it enables teams to move much more quickly through the process of developing and deploying high-quality software. With automation, pushing code changes to a source code repository can trigger a build, test, and deployment process that significantly reduces the time these steps take.
Scaling
Scaling refers to the system that can expand automatically during high workloads and shrink back when the needs are reduced to normal and promote mutual collaboration among teams, facilitated bottlenecks in deliveries, faster feedback cycles, and resilient product updates.
This can involve a variety of measures, such as adding more servers or other resources to the system, implementing load balancing to distribute traffic across multiple servers, and using automation to streamline the process of provisioning and managing resources.
Types of scaling
Horizontal Scaling: Horizontal scaling involves adding more instances of an application or service to handle increased load.
Vertical Scaling: Vertical scaling involves increasing the resources, such as CPU and RAM, of a single instance of an application or service to handle increased load.
Load Balancing: Load balancing involves distributing traffic across multiple instances of an application or service to improve performance and handle increased load.
Infrastructure
Infrastructure is a concept that involves managing infrastructure with the help of code. DevOps teams use technologies like infrastructure as code (IaC), containers, and microservices to deliver fully governed infrastructure environments. A DevOps engineer should have the ability to design, provision, and manage computer ecosystems, whether on-premise or in the cloud. DevOps infrastructure helps to improve the efficiency, reliability, and security of software delivery.
Why DevOps is important?
Shorter development cycles that encourage innovation
When both the teams work together, (development and operations) is an advantage when it comes to releasing new apps, products… It is generally known that the more innovative companies are, the higher their chances of outrunning the competition. Which is essential to increase significantly competitiveness.
More collaboration, better communication
As both teams are together, productivity improves a lot. The DevOps culture is based on achieving the best performance in such a union, instead of worrying about individual objectives.
Reduced deployment failures and faster time to recover
DevOps aims to improve collaboration between all these teams by reducing the time it takes to deploy new features or fix bugs. DevOps also helps to eliminate deployment errors by increasing automation and making changes more transparent.
Efficiency:
Improved resource management Increased efficiency helps speed up development and reduce coding defects and problems. The quantity of manual labor is kept to a bare minimum. Parallel workflows, acceleration tools, scalable infrastructure, continuous integration servers, and much more all help to ensure efficient development and deployment.
Security
Organizations adopting DevOps can more easily incorporate security into their software development practices. This helps them to prevent security breaches from occurring during the software development process. It also helps to improve the overall quality of their software.
