Continuous Integration and Delivery Solutions

Continuous Integration (CI):

 

Continuous integration (CI) is a software engineering practice in which fresh changes are immediately tested and reported when they are integrated to main branch. In traditional software development process integration is generally done at the end of day when every developer had completed their work. As a result of this integration took lots of time and was a very painful process.

CI means when two teams of developers working from different location. But both write code for the same product separately, integrate their changes together in a GIT source repository. Both teams can build software products from the bits they wrote and test that it works in an expected way. Developers generally use a tool called CI Server to do the building and the integration for them. This code runs a self-test to ensure that it is working as expected.

 

According to Paul Duvall, co-author of Continuous Integration, best practices of CI include:

  • Committing code frequently.
  • Categorizing developer tests.
  • Use a dedicated integration build machine.
  • Use continuous feedback mechanisms.
  • Staging builds.

The goal of CI is to provide quick feedback so that if a defect is found in code base, it can be identified and corrected as soon as possible. Continuous integration is a practice that puts the integration phase earlier in the development cycle. CI detects defects early on in development, defects are typically smaller, less complex and easier to resolve.

Continuous Integration

Benefits of CI:

  • Faster product releases
  • Reduce repetitive manual processes
  • Enable better project visibility
  • Less bugs
  • Good quality code
  • Improves team communication
  • Reduce risks

Continuous Delivery (CD):

Continuous Delivery is a software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliable and can be released at any time. In Continuous Delivery our Aim is to build, test, and release software more frequently. Other main goal of continuous delivery is to make feedback loops as short as possible.

Continuous Delivery means each time developers change the code, integrates the code and builds the code. Code should be automatically tested in the environments similar to production. Which gives development team more confidence, that the code will work on the production environment when the code is deployed. If the code passes the test in previous environment.

Continuous Integration

Crucially, the code is only promoted from Dev to Test and Test to Live in the deployment stages. In this way developers gets feedback of their code in each environment. And if there are failures they can understand the errors more easily, where the issue might be and how to get it fixed before the code gets to the production environment.

If an iterative delivery and deployment process is becoming big due to increasing project complexity, Continuous Delivery offers developers a way to get back to doing smaller, more frequent releases which are more stable and reliable.

With Continuous Delivery your software is always ready for production. But when to push it into production is a business decision. So deployment to production is just a manual step. With Continuous Deployment latest working version of the software is pushed to production.

Continuous Deployment:

In Continuous Deployment every commit which developers make goes through the entire pipeline and is put into production, automatically, resulting in many production deployments every day. To achieve continuous deployment you first need to get continuous delivery.

Continuous delivery is about giving the control of the release in the hands of the business, not in the hands of IT. Implementing continuous delivery means making sure your software is always production ready. And any build could be released to users at the touch of a button using a fully automated process in a matter of seconds or minutes.

This in turn relies on automation of the build, test and deployment process, and excellent collaboration between delivery team, development teams and management teams.

DevOps:

Automation of activities are becoming more important to an organization doing Continuous Delivery and DevOps. This is because, in order to achieve continuous and successful process of releasing software that we expect from Continuous Delivery and DevOps, organizations must automate their process. Manual processes are ineffective and very prone to errors.

DevOps Old

DevOps integrates development team and operations teams, in order to improve collaboration, communication and productivity, by automating workflows, infrastructure and continuously measuring application performance and quality. The main goal of DevOps is to improve code quality, integrate continuously, and deliver faster.

DevOps is commonly associated with Continuous Delivery because they both aim to increase collaboration and communication between development and operations teams. And both teams are using automatic processes to build, test and deploy software more quickly, frequently and reliably.

DevOps New

In today's Agile environment teams Co-ordination and Continuous Integration of processes are one of the most critical factors that help enterprises operate and succeed. Kraftic provide 'DevOps as a Service' offering to enable automation of end-to-end delivery processes.

Kraftic’s “DevOps as a Service” help enterprises in bridging the organizational gaps, by automating and integrating process of Development > QA > Building > Testing > Deployment > Monitoring > Support resulting in faster releases with best quality.
