Let's talk about cloud and cloud services. What is a cloud? What is a cloud service? Why do we need cloud services? How we can use cloud services?
Simply put, the cloud is the Internet—more specifically, it's all of the things you can access remotely over the Internet. When something is in the cloud, it means it's stored on Internet servers instead of your computer's hard drive.
Simply put, cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.
Cloud Computing offers resilient computing, fast and effective virtualization, provides you low-cost software, offers advanced online security. In simple words, it’s make the life easier.
The term "cloud services" refers to a wide range of services delivered on demand to companies and customers over the internet. These services are designed to provide easy, affordable access to applications and resources, without the need for internal infrastructure or hardware.
