Key benefits of CD
In this section, we will look at the benefits of CD in more detail. Building upon the idea of the key characteristics of CD being speed, enabling security and progressive practices for software development, and operation and life cycle management, let’s look at the benefits.
There are some industry references. DevOps Research And Assessment (DORA) is an initiative by Google to support organizations to achieve high performance by embracing DevOps according to actionable guidance, DORA metrics (https://cloud.google.com/blog/products/devops-sre/using-the-four-keys-to-measure-your-devops-performance), which can give you a measure of the positive business outcomes from adopting CD. For us, it will be easier to map the key characteristics to the business outcomes and key benefits of CD:
|

Let us now look at the benefits of CD in the cloud.
Benefits of CD in the cloud
Taking one step forward, cloud service providers combined the benefits with the service offerings to facilitate better business outcomes:
|
Characteristics of CD |
Business outcome |
Service offering of cloud service providers |
|
Speed |
% gains on market share from launching new products and services |
Automate the software delivery process through an already tested CI/CD pipeline. Improve developer productivity by removing mundane tasks. |
|
Agility in software development |
% revenue gains on accelerated time to market for changes and new products |
Feature development in increments, which are discrete and small so they can be delivered with agility. |
|
Security |
% reduction of the cost of a long list of risk mitigation and cost avoidance strategies aimed at security breaches |
Cloud providers offer a marketplace of security tools, which can be easily integrated with the pre-built pipelines through APIs. |
|
Simplifying software life cycle management |
% gains from the cost reduction of application failures |
With managed services from cloud providers, it is easier to roll out updates. What used to take weeks and months can now be done in days or even hours. |
|
Collaboration with software operations |
% gains from enhanced team productivity |
Implementing practices adopted by several organizations. Example: AWS has a number of certified DevOps Partners who can provide resources and tooling. |
