Amazon.com Software
Platform:
Amazon uses a customer tracking system, and if a cookie finds your hard drive, you will start seeing recommendations from your prior purchases.
Amazon uses Linux, which offers data recovery tools and has business quality software to work with documents, internet, and networking or multimedia and graphics. It could replace Windows XP but is not a clone of Windows. Oracle is a database designed for the Cloud and is an efficient way of using IT Resources while it continues to improve the user's service levels and can reduce the expenses for IT Specialists. C++ is a collection of commands which will tell the computer to do "something". The collections are codes, and they are either functions or keywords. The keywords are used to build the language; while the functions are simpler tasks that with every C++ program having one service and the main program because it is always used first when a program's executed. Perl Mason is the framework for generating dynamic text and is very useful for creating sophisticated websites. Mason is operated by embedding Perl into text and is popular for creating a web page. Java is the source of most application networked, it is implemental in delivering embedded and mobile apps, games, and web-based content and enterprise software. Java enables you to develop efficiently, deploy and use apps and services. Businesses use it for providing more services and boosts productivity and communication. Java will also allow developers to write software on one platform and have it run on any other. You can create programs that are compatible with web browsers and web services and can combine apps to contribute to creating customized apps. Developers use Java to write powerful and efficient apps for mobile devices and remote processors. Java works well with Oracle. JBoss is an open source alternative to IBM WebSphere, Oracle BEA Services, and SAP NetWeaver. JBoss will enable the Java platform to handle many aspects of programming automatically and is available on Amazon's Cloud. JBoss is a technology of Red Hat and uses Java, it has moved to Amazon's Cloud. Amazon established partnership at the end of 2007, with this Amazon handles the customer tracking and billing while it absorbs the bandwidth and storage fees it charges for the service use and in return. Red Hat gets the licensing money and doesn't need to invest in setting up an infrastructure to deliver the code. Servlets are small programs that run on a server, they usually are referred to as a Java applet and will run within a web browser environment. It is very persistent unlike others, once it starts, it stays in the memory and can fulfill multiple requests. This will make if faster because there is no wasted time setting up the process.

My observation: Amazon needs to have all of these programs implemented to ensure their site runs smoothly. All of the information that I read, there are many of these programs that are intertwined and needed to run another or make another run smoother and more efficient. This is just a summary of what each one is responsible for.
