Cloud and DevOps are very different from each other. As DevOps is a methodology that came into the picture citing many defects and drawbacks of the traditional SDLC methods. It is known as the combination of various concepts that enable both the Development team and Operations team to perform collaboratively to bring the solutions, products, applications, or Software to the market quicker, error-free, rolls out updates more easily and at a much lesser interval, implementing the features based on the customer feedback.
On the other hand, Cloud is a technology that allows companies or organization get access to on-demand computing, data storage, and other computer resources on-demand, rather than setting up their own infrastructure and worrying about fixing errors or issues, to maintain a constant stream of high availability of their services, or applications, etc. Some of the major Cloud service providers are AWS, GCP, and Azure, etc.
