About this Course

Cloud Computing is the delivery of IT resources or different computing services over the internet. These computing services include servers, storage, database, networking and intelligence etc. It allows users to keep the files to remote database and as long as user has access to web, they can access the data and the programme.

Cloud computing is the best for organisations irrespective of their type, size and industry and allow them to use cloud for data backup, virtual desktop, software development, big data and many more. It is also used to create cloud native application, test & build application and to deliver software on demand.  There are three types of cloud computing: Public cloud, private cloud and Hybrid cloud.

In this Cloud Computing course by Uplatz, you will be able to learn the basics and introduction to what is Cloud computing, need for Cloud computing, how organizations are benefitting, the architecture of cloud computing solution, front-end, back-end, the lifecycle of a Cloud service, working in a Cloud ecosystem, and much more.
