4 16))AbstractTraditional on-premises web architectures require complex solutions and accurate reserved capacityforecast in order to ensure reliability. Dense peak traffic periods and wild swings in traffic patterns resultin low utilization rates of expensive hardware. This yields high operating costs to maintain idle hardware,and an inefficient use of capital for underused Web Services (AWS) provides a reliable, scalable, secure, and highly performing infrastructurefor the most demanding web applications. This infrastructure matches IT costs with customer trafficpatterns in near-real Whitepaper is meant for IT Managers and System Architects who want to understand how to runtraditional web architectures in the Cloud to achieve elasticity, scalability, and Application Hosting in theAWS Cloud AWS WhitepaperAn overview of traditional webhostingScalable web Hosting is a well-known problem space.

5 The following image depicts a traditional webhosting architecture that implements a common three-tier web Application model. In this model, thearchitecture is separated into presentation, Application , and persistence layers. Scalability is providedby adding hosts at these layers. The architecture also has built-in performance, failover, and availabilityfeatures. The traditional web Hosting architecture is easily ported to the AWS Cloud with only a traditional web Hosting architectureThe following sections look at why and how such an architecture should be and could be deployed in theAWS Application Hosting in theAWS Cloud AWS WhitepaperHow AWS can solve commonweb Application Hosting issuesWeb Application Hosting in the cloudusing AWSThe first question you should ask concerns the value of moving a classic web Application Hosting solutioninto the AWS Cloud .

6 If you decide that the Cloud is right for you, you ll need a suitable architecture. Thissection helps you evaluate an AWS Cloud solution. It compares deploying your web Application in thecloud to an on-premises deployment, presents an AWS Cloud architecture for Hosting your Application ,and discusses the key components of the AWS Cloud Architecture AWS can solve common web applicationhosting issuesIf you re responsible for running a web Application , you could face a variety of infrastructure andarchitectural issues for which AWS can provide seamless and cost-effective solutions. The following aresome of the benefits of using AWS over a traditional Hosting cost-effective alternative to oversized fleets neededto handle peaksIn the traditional Hosting model, you have to provision servers to handle peak capacity.

7 Unusedcycles are wasted outside of peak periods. Web applications hosted by AWS can leverage on-demandprovisioning of additional servers, so you can constantly adjust capacity and costs to actual example, the following graph shows a web Application with a usage peak from 9AM to 3PM andless usage for the remainder of the day. An automatic scaling approach based on actual traffic trends,which provisions resources only when needed, would result in less wasted capacity and a greater than 50percent reduction in example of wasted capacity in a classic Hosting modelA scalable solution to handling unexpected trafficpeaksA more dire consequence of the slow provisioning associated with a traditional Hosting model is theinability to respond in time to unexpected traffic spikes.

8 There are a number of stories about web3 Web Application Hosting in theAWS Cloud AWS WhitepaperAn on-demand solution for test, load ,beta, and reproduction environmentsapplications becoming unavailable because of an unexpected spike in traffic after the site is mentionedin popular media. In the AWS Cloud , the same on-demand capability that helps web applications scaleto match regular traffic spikes can also handle an unexpected load . New hosts can be launched and arereadily available in a matter of minutes, and they can be taken offline just as quickly when traffic returnsto on-demand solution for test, load , beta, andreproduction environmentsThe hardware costs of building and maintaining a traditional Hosting environment for a production webapplication don t stop with the production fleet.

9 Often, you need to create preproduction, beta, andtesting fleets to ensure the quality of the web Application at each stage of the development you can make various optimizations to ensure the highest possible use of this testing hardware,these parallel fleets are not always used optimally, and a lot of expensive hardware sits unused for longperiods of the AWS Cloud , you can provision testing fleets as and when you need them. This not only eliminatesthe need for pre-provisioning resources days or months prior to the actual usage, but gives you theflexibility to tear down the infrastructure components when you do not need them. Additionally, youcan simulate user traffic on the AWS Cloud during load testing.

10 You can also use these parallel fleetsas a staging environment for a new production release. This enables quick switchover from currentproduction to a new Application version with little or no service AWS Cloud architecture for web hostingThe following figure provides another look at that classic web Application architecture and how it canleverage the AWS Cloud computing Application Hosting in theAWS Cloud AWS WhitepaperAn AWS Cloud architecture for web hostingAn example of a web Hosting architecture on AWS1.
