Cloud computing with Amazon Web Services
Cloud computing can be loosely defined as using scalable computing resources provided as a service from outside your environment on a pay-per-use basis. You use only what you need, and pay for only what you use. You can access any of the resources that live in the “cloud” at any time, and from anywhere across the Internet. You don’t have to care about how things are being maintained behind the scenes in the cloud.
In this series, learn about cloud computing using Amazon Web Services. Explore how the services provide a compelling alternative for architecting and building scalable, reliable applications. This first article explains the features of the building blocks of this virtual infrastructure. Learn how you can use Amazon Web Services to build Web-scale systems.
