When we talk about the Software Delivery Life Cycle, the value is mainly added to the two places. The first is at the software development stage, and second is at a delivery phase when customer feedback is received. Other than this, the associated teams need to manage transportation. The main idea is to ensure faster response from product development to the delivery phase; it may help to assure more value. Although there is a considerable benefit of transportation activities, they do not add value to the entire process.
On the other side, DevOps can help you compute the value equation more effectively. This approach focuses on the phases that add more value and try to organize all the actions for minimized risks. The traditional IT considers all this in conceptual terms, but the biggest trouble is that it treats all different stages with equal importance, or may give equal importance to the wrong stages as well.
The DevOps approach, practices and policies differ more from the traditional IT, and the differences can be observed in terms of a few key dimensions. Here we have listed details about how they may impact the overall performance:
- Batch size:
When we talk about traditional IT, it has to deal with the time-consuming processes, and the releases also get quite disruptive and expensive. On the other side, DevOps believe in considering small batch sizes that are comparatively easier to manage. Even beginners may find them easier to understand, and the process becomes less risky. Even if things get wrong somewhere in-between, it is easier to fix. In short, DevOps release has offered more convenience and responsiveness to the consumers.
- Easy organization:
Traditional IT follows the skill centric silos, and in the typical environment, every new feature has to undergo around 3 to 4 silos before delivering the product to the end consumers. It means 80% of the time is wasted in the back and forth movement between different silos. But on the other side, DevOps operates through dedicated cross-functional teams. The prime goal of every task is to enhance productivity while reducing the cycle time so that customers can stay satisfied.
- Efficient scheduling:
Efficient scheduling is a must in traditional IT organization; hence, organizations need to invest in sophisticated scheduling. On the other side, the DevOps organization schedule is operated on the local cell level. The perfect combination of dedicated teams, smaller batch sizes and automated processes ensure easy scheduling. There is no need to wait so long at every stage as it eliminates the time-consuming decisions and escalations between different phases.
- Information management:
Both traditional IT and DevOps organizations share and generate tones of data; the main difference lies in how teams make use of that valuable information. In the case of traditional systems, the management is quite difficult because of too much data and improper approach. However, in the case of DevOps, it is possible for teams to consume the data more effectively with the automated processes. It eliminates the approvals of the managers, time lag in lengthy reports and queue time as well.
Other than this, DevOps is more effective in terms of easy deployment, cost metrics, success rate, and overall system management.
