January 8, 2019 - by Manan Thakkar
The path to building exceptional software products is often obstructed by several hurdles; disjointed teams often end up affecting release cycles that not only result in a poor quality product, but also add to the overall cost of software development. With the software development landscape evolving so rapidly, traditional software product development and delivery methods are quickly becoming obsolete. If you are looking to improve your time-to-market, enhance your software quality, and set yourself apart from competition, DevOps can enable you to build high-quality software.
According to the 2017 State of DevOps Report, high performing organizations that effectively utilize DevOps principles achieve 46 times more frequent software deployments than their competitors, 96 times faster recovery from failures, and 440 times faster lead time for changes. Continuous delivery, a subset of DevOps, produces software products in short cycles with reliable, manual releases.
Let’s look at what continuous delivery is, how it improves software product development speed, frequency, and reliability, and how it is different from continuous integration and continuous deployment.
Continuous delivery (CDE) is a software engineering approach which enables teams to produce software in short cycles and ensures that the software can be manually and reliably released at any time. It aims to automate the software delivery process by building, testing, and releasing new features and changes with greater speed, accuracy, and frequency.
Moreover, the approach helps reduce the cost, time, and risk of delivering changes by allowing for more incremental updates to applications in production. CDE is enabled through the deployment pipeline, and uses automatic or manual processes to ensure frequent releases of bug-free software into production. The deployment pipeline has three components:
In an industry characterized by long periods of development, looming deadlines, big releases, and stressful remediation of bugs, CDE enables software releases to be small, predictable, less dramatic, and more interesting. When well executed, CDE enables organizations to respond quickly to market fluctuations and customer demands. Listed below are some benefits of CDE:
As market conditions change constantly, CDE lets organizations deliver the business value inherent in new software releases to customers more quickly. By implementing new changes and features more frequently, CDE helps them to stay a step ahead of the competition.
Frequent releases let the application development teams obtain user feedback more quickly. Teams can work in collaboration to develop useful features; if they find that a feature isn’t useful, they simply flick it and move on to the next useful feature. This helps in building the right product.
CDE distributes the responsibility of software delivery more widely. This shared responsibility and collaboration enhances developer productivity and efficiency and makes life easier for everyone. It also brings about significant time savings through automation.
CDE allows developers to release small batches of working software quickly and easily to production. The risks associated significantly decrease, and the release process becomes more reliable. Since the deployment process and scripts are tested repeatedly, finding and fixing problems is easier, and reduces the impact they have on the overall product.
Since CDE takes customer feedback very seriously, it ensures every need is taken care of. Also, as the number of open bugs and production incidents decrease significantly, a higher level of customer satisfaction is achieved.
Continuous Delivery, Continuous Deployment and Continuous Integration are all part of a software product development and delivery mechanism called DevOps. Continuous Integration (CI) is the practice of integrating the working copies of every developer into a central repository several times a day. Since each check-in is verified by an automated build, teams can collaborate better, detect problems early and ensure a better-quality product.
The main aim of CI is to make the process of integration as simple as possible and reduce overall build costs. Since developers regularly integrate their code into a common repository, software product development happens in collaboration and in spurts rather than in isolation and at the end of the cycle.
This way, developers can achieve earlier RI for each feature that is developed, and also receive user feedback quickly. In CD, teams rely on infrastructure that automates and instruments the various steps leading up to deployment. As each integration successfully meets the release criteria, the live application is updated with new code.
As software product development teams around the world get crushed under the weight of constant change, the DevOps approach acts as a silver lining; over 84% of organizations are adopting some aspect of DevOps principles, and the market is expected to reach $12.85 billion by 2025. By enabling software development teams to release working software frequently, it helps in minimizing the occurrence and impact of bugs and ensures a good-quality product is delivered to the end customer.
CDE, an integral aspect of DevOps, aims to minimize the friction points that are inherent in software deployment or release processes. By automating each of the steps for build deployments, it ensures safe code release. When combined with CI and CD, it improves collaboration between various teams and enables the delivery of high-quality software for continued success.
