What is DevOps?

DevOps is a combination of practices and tools for software development and IT operations that aims to increase an organization’s capacity to deliver applications and services faster. This means that the systems’ development life cycle is reduced, and the software produced is continuously improved, achieving high-quality standards. This contributes to better productivity and competence for the organization that uses the application.

How DevOps makes the difference

In a company operating in a DevOps philosophy, the development and operations teams will be working together, or maybe be merged into one team. The same engineers will accompany the application throughout its lifecycle, from development to deployment. Other areas like quality assurance and security will be working closely with the developers. 

The objective of DevOps is streamlining all processes, and make frequent, complete runs of all the development cycle. The integration of individual contributions to a common repository is very regular – almost continuous – and after each compilation, the complete, aggregated software goes through standard testing. This is called continuous integration and delivery (CI/CD), and grants access to a ready, up-to-date version of the software at any given time. Various metrics like performance, speed, and other relevant user interaction variables are actively monitored. 

Communication and collaboration are extremely valued in DevOps. Chat applications and project tracking systems are used to attain high levels of communication within the organization.

The overall satisfaction and effectiveness of your teams are boosted by team collaboration.

Things to note before using DevOps

DevOps is not a software or a tool; it is a philosophy, and a work method that relies on people’s willingness to work together and adopt new approaches.

If your employees are not informed about the benefits or are not ready to change procedures, you may find a counter-productive resistance to change. In this situation, you should first implement a training program.

Notwithstanding the cultural nature of DevOps adoption, there are many tools that you can use to implement these methods in your organization. Amazon offers cloud services for the development of your applications, through AWS. Google Cloud and Digital Ocean are examples of structures that can accommodate your cloud-based, efficient, and flexible application configuration and help you make the leap to a DevOps working philosophy. 

DevOps philosophy: An example

Any organization working on the development, testing and supply of web or mobile applications and related products can greatly benefit from the adoption of DevOps. 

Amazon shifted to a DevOps work philosophy after making great investments in dedicated servers that proved to be a waste of money. The company, to accommodate traffic spikes and the sales increase in the busy Christmas season, greatly expanded server capacity; as a result, about 40% of it was wasted. After the shift to a DevOps model, all the services were moved to the Amazon Web Services (AWS) cloud, allowing instantaneously scaling up or down, reducing costs, and even decreasing the number and duration of outages, increasing the company’s revenue. Within a year of the change, Amazon was deploying code every 11.7 seconds, working in a continuous delivery model.
