DevOps Vs Traditional Approaches

Introduction

For software development, two types of approaches exist one is traditional, and another is DevOps. Traditional software development (SDLC) approaches include the waterfall and spiral models. This article gives a comprehensive overview of the differences between DevOps and traditional approaches.

 

DevOps is an arrangement of development and IT operations with improved communication and collaboration. Traditional approaches need to be more scalable, limiting their collaboration ability. As technology evolves, more flexibility is required, and traditional approaches are less flexible than DevOps. 

Why it is needed

  • In traditional software development (SDLC), the development and operations teams worked completely segregated, needing more time. While in DevOps, both teams work together, understanding each other’s concerns and views, thus being able to build and deliver resilient software products at a fast pace. 



  • Organizations transition from traditional approaches to DevOps for software development because DevOps provides better options for development, scalability, customer satisfaction, cost reduction, and software optimization. 

How do traditional approaches compare to DevOps?

When comparing Traditional IT Ops to DevOps, it’s clear how they differ and why DevOps is increasingly embraced by organizations worldwide. 

Planning & Organization

  1. Batch Sizes

 

  • Traditional approach: Large-scale releases are the focus of traditional processes, which are significantly risky due to the amount of work required. 
  • DevOps: Small batch sizes are simple, easy to test, and less risky. If things do not work, the impact is minimal and is much easier and faster to fix. 

 

  1. Scheduling: Centralize to Decentralize & Continuous

 

  • Traditional approach: A Traditional IT organization is built around effective scheduling. Projects frequently demand access to SMEs or infrastructure due to the pooling of resources. To prevent this, enterprises have invested in sophisticated scheduling planning systems.
  • DevOps: Scheduling is pushed down to the local cell level in a DevOps organization. Smaller batch sizes, specialized teams, and automated procedures all work together to make scheduling easier to manage.

Performance

  1. Software release



  • Traditional approach: The release of software into production is a high-risk initiative in a traditional IT organization. The procedure is carefully controlled, overseen at the highest levels, and requires participation from every company division.
  • DevOps: The goal of DevOps organizations is to minimize the impact of software release. They minimize risk by automating testing, ensuring all environments are in sync, and minimizing batch sizes.



  1. Information

 

Both kinds of organizations produce and exchange a vast amount of data. How the teams use the data makes a difference.



  • Traditional approach: Data is gathered by experts (operations team), combined with other data into a report, approved by management, and shared with other managers, who then send it to their specialist teams (testers, developers, etc.).
  • DevOps: The team cell is responsible for gathering and producing the data inside a DevOps organization. The time lag associated with producing long reports, obtaining manager approvals, and waiting in line is eliminated because the data is processed within the team. As a result, the team can read and respond to the data rapidly, which shortens the time it takes to provide feedback.

Culture

  • Traditional approach: Traditional methods are risk-averse, focusing on no failure. The culture is based on doing all in its power to keep the business running smoothly, which puts a lot of pressure on them to get everything perfect.
  • DevOps: A DevOps organization understands that failure is inevitable. As a result, they prefer to decide when and how they fail rather than trying to eliminate it. They prefer to fail small, fail early, and recover fast.  

Measure

  1. Metric: Cost & Capacity to Cost, Capacity, & Flow



  • Traditional approach: The traditional approach utilizes a capacity and cost model to determine how much they can accomplish for the least amount of money. The fundamental issue with this technique is that it can be challenging to reduce prices while maintaining the same capacity. As a result, many businesses that use traditional methods frequently outsource work.
  • DevOps:  DevOps has added this matrice by including “flow,”. A company is compelled by flow to examine its end-to-end cycle time, find waste areas, determine the real productive time, measure quality, and concentrate on tasks that contribute the most value.

 

  1. Definition of Work Done



  • Traditional approach: In traditional IT, “work done” refers to the specialist doing “only” their task before passing it along.This approach results in a loss of quality and a lack of responsibility.
  • DevOps: DevOps create a cross-functional team where everyone’s accountable for completing the task. Every member of the many IT departments is represented in this “cell” structure. They are all held responsible for only one task, so they all arrive at the same definition of work done – releasing high-quality software.

In conclusion, DevOps teams get more work done and quickly resolve issues. 

Teams spend more time improving things, less time fixing things, recover from failures faster, and release applications more than twice as fast as Traditional IT Ops. The goal of bringing high-quality software to market is shared by all members of the various IT departments working cooperatively.
