Cloud computing and its technologies: JavaScript and Java

December 8th, 2010 Leave a comment Go to comments

Cloud computing and distributed networking enhances the power of client computers by providing content or technology at the server end or over the Web. However, client end technologies are also often required. Java and JavaScript are two such client end technologies that are frequently employed in cloud computing networks and VPS hosting services. Although their names suggest otherwise, Java and JavaScript are not related to each other in terms of how they developed and their naming is coincidental.

Client side technologies have been influenced by the ECMAScript conventions and standards. Netscape and Microsoft were among the software teams to develop this scripting language – a kind of universal language that should ideally be adhered to my new technologies in the same vein.

JavaScript is one of the languages that aims to be ECMAScript compliant. Typically found in host environments that require access – on a programmatic level – to computational objects. It is an object oriented scripting language and resides on the client side. It can be described as dynamic rather than static insofar as it can be used in user inputs and in various other ways to change a web page’s or application’s content. It is a functional programming language and because of its prototype status it is more common than a lot more languages like it. Self and Scheme programming languages are both heavily influenced in the design elements found in JavaScript. It is usually enabled through the technology of a web browser.

Java is also an object oriented language and is typically compiled in the form of applications run on a Java Virtual Machine (JVM) via the class files or bytecode. The type of computer on which the software runs is not relevant. It is built with distributed services in mind when you consider the “write once, run anywhere” philosophy of the developers of the software.
