DevOps is a term that has been thrown around for the last few years, and it is one of those words everyone seems to be using but not many people are sure what it means.
DevOps can be defined as a cultural change in which software developers take on more responsibility for quality assurance and operations tasks traditionally performed by dedicated teams of IT professionals. This blog post will highlight everything you need to know about DevOps and its role in the software development life cycle.
What Exactly is DevOps?
So what exactly is DevOps? It's a combination of two words, "development" and "operations," which refers to the collaboration between software developers and IT professionals. Contrary to popular belief, DevOps is not a specific technology. Instead, it's a mindset involving collaboration, communication, and automation for software delivery among different departments within an organization.
Why is DevOps Beneficial to Deploy?
A key goal of DevOps is to develop software faster, which allows organizations to react more quickly to changes in the marketplace and deliver innovative products. For example, a company that develops a new digital product can typically deliver it into production much sooner than competitors who use traditional development methods.
Another benefit of DevOps is the ability to fine-tune and continuously improve an application in a production environment, which helps organizations reduce the length of time between releases and respond to issues more quickly. As a result, many organizations have adopted DevOps practices to improve their efficiency and quality of service while reducing the time it takes to deliver new features and products.
Other vital benefits include reducing the cost of coding errors and responding quickly to market changes, which ultimately help organizations deliver innovative products faster than their competitors.
Benefits of Speed & Stability Optimization
DevOps practices are designed to enhance the speed and stability of software delivery while cutting operational costs. DevOps increases software development and deployment efficiency when appropriately used by aligning business goals with quality assurance and operations functions.
Through this collaboration, companies can quickly deliver new features and updates to customers, providing feedback on applications in a production environment. This collaboration also improves communication among departments, leading to greater efficiency and reduced expenses spent on deploying software.
Understanding Waterfall and Agile Methodologies
When organizations look to integrate DevOps into their software development life cycle, various methodologies can be applied. Two common software development methodologies that are incorporated into DevOps practices are Agile and Waterfall.
Waterfall is a sequential development process in which you perform steps one at a time (like building blocks), and once you begin creating an application, there's no going back to change it later on. All changes must be made before the next step can be performed. When a problem is identified in the application, you have to go back and rework previous actions before moving forward again. Thus, this development method is not very flexible and can delay an application by weeks or even months if problems are encountered later in the cycle.
Waterfall methodology can often lead to lengthy testing cycles, which can result in dissatisfied customers if not managed thoroughly. As a result, customers might not receive the applications they need when they want them. The Waterfall method can present certain challenges when developing software. It doesn't allow you to rapidly make changes to an application or fix problems that arise as work progresses. However, it offers the advantage of providing high-quality applications that can be thoroughly tested and reviewed before deployment.
Agile is a software development process that focuses on delivering small chunks of applications (usually called "features") to customers quickly, typically every two weeks or so. Because each feature is developed independently of the others, you're able to deliver them more quickly than methods such as waterfall.
Small groups of developers work on the features and combine them later in the development cycle using "integration testing" to ensure they all work together. Agile methodology allows for rapid feature delivery, with continuous improvement and iteration throughout the development process. It also allows teams to develop working software from a business perspective at an early stage, which gives the customer and developer a chance to engage early in the process.
Lean-Agile development methodologies also consider that there are no perfect applications, and you should strive to create working software as soon as possible so users can use it before the full completion of an application. This means that some features might be missing or not fully developed; however, the product's value is realized early in its development cycle.
Lean-Agile development methodologies provide faster time-to-market and rapid feature delivery while still maintaining quality assurance standards, potentially saving significant development costs for the organization.
DevOps is a paradigm that has changed the way software development teams work. It's not just for large companies and enterprise-level projects anymore; it can be used by any company, no matter how small they are or what type of project they're working on.
The goal of DevOps is to create a business that's able to react quickly to the needs of its customers. By employing Agile methodologies and Lean development strategies, you can help your company and its development projects meet the ever-changing demands of your customer base.
