State of Ajax: Progress, Challenges, and Implications for SOAs
By Martin English | August 21, 2005
Ajax hasn’t even been big a year yet and already open source development tools by the dozen are pouring out. Not to mention big names like TIBCO and Microsoft already have previews on the way of full-fledged IDEs for developing Ajax applications. Ajax may be the biggest software development story of 2005.
Dion Hinchcliffe has a detailed article about how Ajax has evolved over the last six months and assesses the current state of tools, libraries, and mindshare.
Something I’m picking up from watching stories about intranet AJAX developments is that since it requires high performance back-end XML services, it may inadvertently up being a driving force for Service-Oriented Architecture (SOA) for many organizations.
Bear in mind, though, that the point of providing SOA services is to be able to combine them and use them in a manner that is consistent and abstracted from the source application(s). SOA operates at the integration level… between apps. To assume that services should be tied together at the browser assumes that architecturally significant web services are so fine-grained that they would be useful for driving a user interface. That is nonsense.
Another issue, vaguely related, is the movement from “local” to “remote” data storage. In fact, it was going on before AJAX – since people went from fat client software towards more streamlined C/S replacements, due mostly to convenience and easier features, server updates etc. Examples include web mail (i.e. outlook v hotmail).
