Introduction to Amason Cloud computing applications

What is the benefit of the cloud, the advantages of the cluster will be everyone can think of, super storage capacity, large-scale integrated computing power and system load capacity, and cloud can be imagined as a larger cluster, theoretically its storage and computing capacity is almost unlimited, So the greatest benefit is that it greatly reduces the cost of data storage, including the cost of money. The cloud's first estimate is that Google's goal is to use it to distribute computer clusters around the world to reduce the cost of data storage, thereby bringing deeper cloud computing ideas.

In the December 2008 issue of the Programmers monthly magazine, there is a very practical article-the practice of cloud computing based on Amason WEB service online Trading application, which describes the practice of three services in Amasonwebservice Cloud computing services AWS from an application perspective:

1. Amason Elastic Compute Cloud (Amazon EC2), he provides operating system-level platform support primarily through Xen virtualization technology, imagining that users can come out of a virtual computer directly from the cloud, Cool ideas no longer need the basics of hardware and get directly to the "computer" I want from the cloud.

2. Amason Flexible Payment Service (FPS), he offers online trading support similar to PayPal

3. Amason Simple Storage Service (Amazon S3) provides storage services that are tightly integrated with 1.

Of course, many of these services need to be registered Amason AWS to obtain certification, and most of the time based on cloud services will be charged. We take Web services for example to simply look at how Amazon S3 can be applied in our web services. First of all normal a Web site requires a hosting service provider-the host server. Since the cloud has such a powerful storage capacity is not stored in the cloud, of course, it can be completely the site of the large files stored in the AmazonS3, of course, in the Amason S3 flow is also to collect fees. So you have to calculate the cost of how much data you store is the most cost-effective, and I feel that the cost will be cheaper as cloud computing matures.

Of course, his costs are also:

The total price is 28.56 dollars is relatively cheaper. If you combine Amason's CloudFront, you can use Amason cache servers all over the world to publish your site content so that you can reach a very fast access request wherever you are.

This is a very common application of the cloud to provide storage services, in fact, Google's corporate suite also has a lot to be included in the cloud computing applications, such as Google site, corporate email and so on. My mailbox Meatyustar.info, is through the DNS CNAME direct point to Google's application service domain name to obtain the mailbox service, as to this service actually happened where, that also is not my concern matter. I feel like I've been talking about SaaS software, the service model, but it's just a manifestation of cloud computing.

Amazon's FPS and EC2 services are not discussed here, you are interested to see the relevant articles or can look for programmers 2008 12 Introduction, really good very practical is worth a look.
