What Are The 6 Best Practices Of Using Devops (2021)?
DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). It aims to shorten the systems development life cycle and provide continuous delivery with high software quality. DevOps is complementary with Agile software development; several DevOps aspects came from Agile methodology.
As DevOps is intended to be a cross-functional mode of working, those who practice the methodology use different sets of tools — referred to as “toolchains” — rather than one. These toolchains are expected to fit into one or more of the following categories, reflective of key aspects of the development and delivery process
Coding — code development and review, source code management tools, code merging.
Building — continuous integration tools, build status.
Testing — continuous testing tools that provide quick and timely feedback on business risks.
Packaging — artifacts repository, application pre-deployment staging.
Releasing — change management, release approvals, release automation.
Configuring — infrastructure configuration and management, infrastructure as code tools.
Monitoring — applications performance monitoring, end-user experience.
DevOps Model & Benefits:
Devops: A Cultural change:
Transitioning to DevOps requires a change in culture and mindset. At its simplest, DevOps is about removing the barriers between two traditionally siloed teams, development and operations.
With DevOps, the two teams work together to optimize both the productivity of developers and the reliability of operations.
They strive to communicate frequently, increase efficiencies, and improve the quality of services they provide to customers.
They take full ownership for their services, often beyond where their stated roles or titles have traditionally been scoped by thinking about the end customer’s needs and how they can contribute to solving those needs.
Quality assurance and security teams may also become tightly integrated with these teams.
Best Practices
1.CONTINUOUS INTEGRATION is a practice where
developers regularly merge their code changes into a central repository, after which automated builds and tests are run. The key goals of continuous integration are to find and address bugs quicker, improve software quality, and reduce the time it takes to validate and release new software updates.
2.CONTINUOUS DELIVERY is a practice where code changes are automatically built, tested, and prepared for a release to production. It expands upon continuous integration by deploying all code changes to a testing environment and/or a production environment after the build stage. When continuous delivery is implemented properly, developers will always have a deployment-ready build artifact that has passed through a standardized test process.
3.The MICROSERVICES architecture is a design approach to build a single
application as a set of small services. Microservices are built around business capabilities; each service is scoped to a single purpose. You can use different frameworks or programming languages to write microservices and deploy them independently, as a single service, or as a group of services.
4.INFRASTRUCTURE AS CODE is a practice in which infrastructure is provisioned and managed using code and software development techniques, such as version control and continuous integration. The cloud’s API-driven model enables developers and system administrators to interact with infrastructure programmatically, and at scale, instead of needing to manually set up and configure resources.
5.Organizations MONITOR metrics and logs to see how application and infrastructure
performance impacts the experience of their product’s end user. By capturing, categorizing, and then analyzing data and logs generated by applications and infrastructure, organizations understand how changes or updates impact users, shedding insights into the root causes of problems or unexpected changes.
6.Increased COMMUNICATION & COLLABORATION in an organization is one of the key cultural aspects of DevOps. The use of DevOps tooling and automation of the software delivery process establishes collaboration by physically bringing together the workflows and responsibilities of development and operations.
