As we roll towards 2013, the tide is turning; leading online brands, including Apple, Best Buy, Four Seasons Hotels, and Rue La La to name a few, are now putting the features of HTML5 to use on their desktop sites with the goal of enhancing the online experience for customers using modern browsers like Chrome, Firefox, and IE9. We are at an inflection point: With consumer adoption of HTML5-“capable” desktop browsers widespread and web developer understanding of the technology rapidly maturing, HTML5 is no longer an emerging toolset for mobile and tablet development. Instead, it is fast becoming the de facto standard for web experience innovation across touchpoints.
As eBusiness teams evaluate the business case for HTML5 on the desktop, it is important to remember that this not an all-new technology— it is a collection of individual features that extend the existing W3C HTML standards. The decision to start using HTML5 or CSS3 does not require any changes to or throwing away of existing code. Instead, eBusiness teams can simply enhance the user experience of existing sites by incrementally using the new features of HTML5. HTML5 puts more tools in the box, but it doesn’t change the fundamentals of how to build the website.
Open Web developers tend to use a variation of the façade pattern for their applications but refine the pattern to focus on standard web formats and protocols and services delivered via the Web — so we refer to it as the open Web façade. Developers draw on three bodies of de jure and de facto standards to implement the open Web façade pattern:
Client standards. Application clients based on a body of emerging standards collectively labeled HTML5.
Service plane standards. A service plane that exposes interfaces using the REST pattern and resource-oriented architecture principles. These services are often called RESTful web services.
Virtual infrastructure standards. A highly virtualized server tier (often a public cloud service) that is easy to deploy initial solutions to but that is also able to scale up or down on demand to meet surges in capacity.
