Infrastructure As a Service The focus of this book is the idea of IaaS. I spend a lot of time in this book using examples from the major player in this environment, Amazon Web Services. A number of significant AWS competitors exist who have different takes on the IaaS problem. These different approaches have key value propositions for different kinds of cloud customers. AWS is based on pure virtualization. Amazon owns all the hardware and controls the network infrastructure, and you own everything from the guest operating system up.

Amazon S3 enables you to place persistent data into the cloud and retrieve it at a later date with a near certainty that it will be there in one consistent piece when you get it back. Its key benefit is that you can simply continue to shove data into Amazon S3 and never worry about running out of storage space. In short, for most users, S3 serves as a short-term or long-term backup facility. CLEVERSAFE STORAGE Cloud storage systems have unique challenges that legacy storage technologies cannot address.

EC2 servers in particular see both cost savings and greater efficiencies in accessing S3. To secure your network within the cloud, you can control virtual firewall rules that define how traffic can be filtered to your virtual nodes. You define routing rules by creating security groups and associating the rules with those groups. Com allows port 80 and port 443 traffic from the public Internet into its servers, but allows no other incoming traffic. Amazon Simple Storage Service (S3) Amazon S3 is cloud-based data storage accessible in real time via a web services API from anywhere on the Internet.
