It is worth noting that DevOps culture is not just about tools or techniques, and a good understanding of the values and principles behind DevOps, as well as the ability to work well in a collaborative, multidisciplinary team are also important qualities.
More and more organizations have adopted DevOps practices to streamline software development, increase developer productivity, and enhance continuous delivery workflows to deliver better software faster.
Approx 70% of organizations that use DevOps practices have improved the quality of their deployment
What is DevOps?
DevOps is a flexible framework of software development practices organizations use to create and deliver software by aligning and coordinating software development efforts — "Dev" — with IT operations — "Ops".
As DevOps pioneer Patrick Debois first described it in 2009, DevOps is not a specific technology, but a tactical approach. By working together, development and operations teams can eliminate roadblocks and focus on improving how they create, deploy, and continuously monitor software.
The shift to DevOps is critical for organizations to support the ever-accelerating development speeds that both customers and internal stakeholders demand. With the help of cloud-native technologies, open-source solutions, and agile APIs, teams can now deliver and maintain code more efficiently than ever. Combining development with operations and the processes that support them enables organizations to keep pace with the speed of development.
Why DevOps is important?
DevOps describes a culture and set of processes that bring development and operations teams together to complete software development. It allows organizations to create and improve products at a faster pace than they can with traditional software development approaches. And, it’s gaining popularity at a rapid rate.
5 important factors are:-
Reduce deployment failures, rollbacks and time to recover.
shorter development cycle, faster innovation.
Improved collaboration and communication.
Improved efficiency
Reduce cost and IT headcount.
What are DevOps engineering tools and platforms?
The choice of DevOps engineer tools and cloud platforms for DevOps engineers are those that meet an organization’s current needs. They have the ability to scale and meet changing business key performance indicators and requirements for continued success in the future.
The following are 12 popular DevOps tools and platforms to consider implementing:
GitHub. Version control system and source code management with end-to-end DevOps platform and cloud-hosted Git services.
Jenkins. Open source CI/CD pipeline tool with extensible server automation for distributed builds and scaling.
Atlassian Jira. Issue tracking system to manage issues, trigger workflows, and track code changes.
Selenium. The open-source automated browser and testing tool.
Ansible. Open source, a cross-platform automation tool for resource provisioning.
Chef. Infrastructure as code (IaC) configuration management tool.
Amazon Web Services (AWS). Automated DevOps throughout AWS hybrid-cloud environments.
Codefresh. CI/CD solution that automates GitOps workflows for cloud-native applications.
Kubernetes is a Container orchestration platform offering orchestration, automation, security, governance, and other capabilities.
Docker. Open source software containerization platform.
Puppet. Configuration management.
Microsoft Azure. DevOps services that offer agile tools to simplify collaboration and work item tracking.

The fundamentals of DevOps
DevOps is a cultural shift that requires vision, planning, executive buy-in, and tight collaboration to successfully establish a more integrated way of developing and delivering applications.
Because DevOps is a continuum, these practices should also be continuous and ongoing. This chapter covers the basic tenets or practices that form the fundamentals of adopting a DevOps approach.
Continuous integration
Continuous integration (CI) is a software development practice in which developers regularly commit their code to a shared repository. Because microservices architecture is distributed, continuous integration allows developers to own discreet, manageable chunks of code and individual features and work on them in parallel.

Because microservices architecture is distributed, continuous integration allows developers to own discreet, manageable chunks of code and individual features and work on them in parallel.
Continuous delivery
While CI focuses on regular, independent code updates to a central repository, continuous delivery (CD) focuses on releasing completed code blocks to a repository at regular intervals. These blocks of code should always be in a deployable state for testing or release to production.
Continuous delivery is often confused with continuous deployment — the next process in line, which releases finalized code into production. Deployment is the act of making new and updated software available to end users. Accordingly, the CD primarily denotes "continuous delivery," or both "continuous delivery and deployment," but rarely just continuous deployment.
CD takes code and adds it to a repository, such as GitHub.The end goal is to increase release consistency by perpetually keeping code in a deployable state. Software development becomes more nimble and more predictable as a result.
Benefits of DevOps?
As teams embrace shifts in both culture and processes, DevOps’ holistic approach to software and infrastructure creation can pay dividends, even at the organizational level. Once teams have established some best practices and key metrics to monitor and manage, teams can expect to see some core benefits.
Increased speed of delivery
Increased frequency of releases
Reduced risk and increased release confidence via higher-quality software
Developer empowerment
Better collaboration and developer productivity
Increased security
Reduced mean time to resolution (MTTR)
Increased software reliability and resiliency
DevOps principles
DevOps adoption has produced several principles that have evolved (and are still evolving). Most solution providers have developed their own variants. All these principles take a holistic approach to DevOps, and organizations of all sizes can adopt them.

In conclusion
In order to make the journey to the cloud smooth, efficient, and effective, technology companies should embrace DevOps principles and practices.
The DevOps approach is based on the deep involvement of both the operational and development teams during all steps of product creation. It may take some effort to integrate DevOps into the process, but eventually, it will help to create an agile and scalable system that’s ready for rapid change and growth.
