Azure Pipelines/Microsoft Azure
Azure is a provider of cloud service that offers different kind of services such as computation service, storage, databases, machine learning and etc. Azure allows user to rent these services where user just need to pay for resources & services that the user is using. It is somewhat similar to ‘Power Consumption Analogy’.
On the other side DevOps is an approach that helps in developing the software faster. Basically DevOps is an umbrella under which approaches of developer and operator falls.
It makes sure to continuously integrate the software, build it, test it and deploy it to the end user so the role of DevOps is to bring developer & operator together.
