Google was the first major Cloud provider to deliver per second billing for its Infrastructure as a Service Compute offering, Google Compute Engine. Fine-grain billing is a big cost savings for workloads that are bursty, which is a lot of them. Many of the best-known GCP services billed by the second, including Compute Engine and Kubernetes Engine and you'll learn about them and others in this course. Compute Engine offers automatically applied sustained use discounts which are automatic discounts that you get for running a virtual machine instance for a significant portion of the billing month. Specifically, when you run an instance for more than 25 percent of a month, Compute Engine automatically gives you a discount for every incremental minute you use for that instance. Compute Engines Custom Virtual Machine types lets you fine-tune virtual machines for their applications, which in turn lets you tailor your pricing for your workloads.
