Understanding Traditional Development

Traditional development, often referred to as the Waterfall model, represents a historical approach to software development. Picture this: you're building a bridge across a river. In the traditional development world, you'd sketch out detailed blueprints, gather all the necessary materials, and start constructing the bridge from one end to the other in a meticulously planned sequence.

Once the bridge is complete, you test it thoroughly to ensure it can carry the anticipated loads and withstand various conditions. Only then is it open for public use.

Similarly, in traditional software development, the entire project is meticulously planned upfront, with requirements gathered in detail, and development proceeds through a sequence of distinct phases – planning, design, implementation, testing, deployment, and maintenance. Each phase must be completed before moving on to the next, much like building the bridge section by section.

Pros and Cons of Traditional Development

Traditional development has its strengths and weaknesses, much like our bridge-building analogy

Pros

  1. Predictable Timelines: Just as a bridge construction project can often provide a fairly accurate completion date, traditional development can offer a predictable timeline. You have a clear roadmap, and each phase has well-defined objectives and milestones.

  2. Clear Responsibilities: In the bridge project, the roles of architects, engineers, and construction workers are distinct and well-defined. Similarly, traditional development assigns clear roles and responsibilities to different teams, ensuring specialization.

Cons

  1. Siloed Teams: Much like having separate teams for designing and constructing the bridge can lead to communication gaps, traditional development often results in siloed teams. Teams work in isolation during different phases, which can lead to misunderstandings and delays.

  2. Slow Deployment: Building the entire bridge before opening it can be time-consuming, as is traditional development. The long development cycle means that software updates or new features may take months or even years to reach users, resulting in slow deployment.

In this fast-paced digital world, where software users expect frequent updates and improvements, traditional development can sometimes feel like building a bridge in an era of rapid transit systems. As a result, the software development industry has shifted its focus to embrace a more agile and responsive approach, leading us to the world of DevOps.

What is DevOps?

Imagine a high-speed relay race where a team of runners must pass a baton seamlessly to the next runner to achieve maximum speed and efficiency.
