This article, excerpted from Amazon Web Casework in Action, shows that you are able to run any appliance on AWS by appliance one or a aggregate of altered services. The four examples we present in this commodity will accord you an abstraction of what you can do with AWS.
When you are hosting a web boutique on-premise, you would about hire a server in a abstracts center. On this server you run a web server, administration the requests from your users and a database autumn your articles and orders. You can run this exact aforementioned bureaucracy in AWS as amount 1 shows.
Figure 1: Comparison of how to run a web boutique on-premise and on AWS
You ability ask yourself: Why should I do that? Only because I don’t accept to affliction about the database any longer? But attending at how the bureaucracy could be bigger to absolutely account from AWS in three steps.
Figure 2 compares the on-premise bureaucracy with the added AWS setup.

Any web appliance can be transferred to AWS after any constraints. You can optionally use account like a SQL database or an article abundance to get the best out of the cloud.
It’s accessible to alteration any appliance to AWS, alike an action application.
It is accessible to run an action appliance on AWS. To do so you charge to ascertain a basic arrangement in the billow and affix it to your accumulated arrangement through a VPN connection. Controlling admission and attention mission-critical abstracts can be accomplished with subnets and admission ascendancy lists for the advice amid them. You can ascendancy cartage to the Internet by the use of NAT and firewalls. Appliance servers can be installed on basic machines to run your JEE application. If you like, you can abundance your abstracts in a SQL database account (e.g., Oracle Database Action Edition or Microsoft SQL Server EE). Amount 3 illustrates this scenario.

If you accept to accord with huge amounts of abstracts to accommodated acknowledged or business archival requirements, the aing use case will appearance you, how you can handle this with AWS.
A book server to allotment abstracts amid users can be begin in every company. Autumn abstracts consistently creates to problems.
To save costs and access abstracts security, it is accessible to apparatus this use case on AWS. Abstracts is transferred to a aerial accessible article store. A accumulator aperture makes it abounding to buy and accomplish arrangement absorbed accumulator and a advancement on-premise. A basic band accouter can booty over the assignment of archiving abstracts for a continued time. Amount 4 illustrates the accomplishing of this use case on AWS and compares it to an on-premise solution.

You can additionally architectonics adult accountability advanced systems with AWS.
Murphy’s law applies to IT infrastructure: annihilation that can go amiss will go wrong. On AWS there are two blazon of services: accountability advanced casework and casework that can be acclimated in a accountability advanced way. Amount 5 shows a fault-tolerant architecture. The database account is offered with archetype and failover handling. A distinct basic server, acclimated as a web server in this example, is not accountability tolerant. But with the advice of a amount aerialist and the achievability to barrage assorted servers in altered abstracts centers, accountability altruism can be achieved.

You now accept a ample abstraction what you can do with AWS. Generally speaking you can host any appliance on AWS. You will now apprentice how you collaborate with AWS to about-face the arrangement diagrams into reality.
