Cloud computing and Google Cloud
1. Cloud computing and Google Cloud
Let's start at the beginning with an overview of cloud computing. Cloud computing is a way of using information technology, IT, that has these five equally important traits. First, customers get computing resources that are on-demand and self-service. Through a web interface, users get the processing power, storage, and network they need with no need for human intervention. Second, customers get access to those resources over the internet, from anywhere they have a connection. Third, the cloud provider has a big pool of those resources and allocates them to users out of that pool. That allows the provider to buy in bulk and pass the savings on to the customers. Customers don't have to know or care about the exact physical location of those resources. Fourth, the resources are elastic–which means they're flexible, so customers can be. If they need more resources they can get more, and quickly. If they need less, they can scale back. And finally, customers pay only for what they use, or reserve as they go. If they stop using resources, they stop paying. That's it. That's the definition of cloud. Google Cloud offers a variety of services for architects and developers to use to build solutions. Some might sound familiar, like virtual machines, whereas others might represent a totally new paradigm, like Google Kubernetes Engine. A common first request that organizations make of Google Cloud is to run some code in the cloud. Google offers a range of computing services to help fulfill that request. We'll explore these options next.2. Let's practice!
