Seeing Infrastructure as a Service
Transcript of Seeing Infrastructure as a Service
as a Service Amazon's Elastic
Compute Cloud Other Iaas Companies Examining IaaS-Enabling Technology Trusting the Cloud EC2 pricing EC2 Compute Units Platforms and storage Exploring Amazon EC2 IaaS Tracing Iaas to ISP Tracing IaaS to ISP IaaS is the delivery of computer
hardware as a service.
The IaaS customers rent
computing resources instead
of buying and installing
them in their own
data center. The dawn of IaaS when Amazon launched its Electric Cloud Computing (EC2) service in 2006. But long before then, Internet service providers (ISPs) were happily renting out servers to companies.
In fact, if you compare what customers get from an ISP to what they get from an IaaS, you will see that it’s pretty much the same capability. Renting
Why do companies rent external infrastructure
to run their Web sites?
- Aggregation of resources
- Speed to deployment
- Security Currently the highest profile IaaS operation is Amazon’s Elastic Compute Cloud.
Customers can rent computers or virtual
instances to run their own computer applications. EC2 provides a Web services interface through which a customer can create virtual machines and load and run any software. EC2 uses Xen virtualization to create and manage its virtual machines.
Xen is a popular, proven open-source hypervisor — a thin layer of software that allows other operating systems to run on the same system.
One EC2 Compute Unit equals a 1.0–1.2 GHz 2007 AMD Opteron or 2007 Intel Xeon processor. Linux

Microsoft’s Windows Server 2003
This covers most of the common operating systems that companies might want to use. Amazon’s primary charges are of two types: Rackspace The ability to offer IaaS requires software that can manage the infrastructure that’s being shared.
Two technologies are worth drawing attention to: The trusted cloud includes services that are: Following the ISP pattern Much of the IaaS market will follow in the path of the ISP market. The ISP model has been proven and some large ISPs run millions of Web sites.
Usually the ISP service paid for based on the amount of resources used over time.
IaaS takes the ISP model to a new level. Hourly charge per virtual machine
Data transfer charge What does Amazon provide? GoGrid Other It focuses primarily on attracting customers that want to host Web sites and its charges are more oriented to Web site usage.
It charges for: Storage space
