For a company that provides customized software and products and has recently moved its infrastructure and applications to the cloud, the best option to help with automated integration, development, testing, and deployment in the cloud is DevOps.

Understanding DevOps: DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). It aims to shorten the systems development life cycle and provide continuous delivery with high software quality1.

Automated Processes: DevOps encourages automating the software delivery process, which includes:

Continuous Integration (CI): Developers merge code changes into a central repository, after which automated builds and tests are run.

Continuous Delivery (CD): The code changes are automatically built, tested, and prepared for a release to production.

Continuous Deployment: This goes one step further than continuous delivery. Every change that passes all stages of the production pipeline is released to customers. There’s no human intervention, and only a failed test will prevent a new change to be deployed to production1.

Benefits of DevOps:

Improved Collaboration: DevOps practices encourage collaboration between development and operations teams, resulting in better communication and collaboration.

Increased Efficiency: Automation and consistency help your team do more, in less time, with significantly fewer bugs.

Faster Resolution of Problems: Continuous monitoring and automated testing mean you can identify and address bugs more quickly, often before they become a problem for users1.

Why Not the Others?:

A vulnerability assessment tool is used for identifying and assessing the vulnerabilities in a system, not for deployment.

SIEM (Security Information and Event Management) is used for real-time analysis of security alerts generated by applications and network hardware, not for deployment.

A dashboard is a type of graphical user interface that provides an overview of a system’s key performance indicators, not for deployment.
