Vignette High Performance Delivery
More and more, Web users expect to be treated as the unique individuals they are, whether they are conducting personal business online, being entertained, or doing research. In response to this audience expectation many organizations want to offer online interactions that are customized, personal and meaningful. But as these organizations quickly learn, delivering a dynamic, personal online experience is detrimental to Web site performance, and a slow Web experience is another thing that today's Web users won't stand for.
Traditionally, delivering a highly customized online experience, while maintaining Web site performance, has been a very expensive proposition. Some organizations try to keep up with user expectations with ever-greater investments in hardware, but the Web audience is growing faster than almost anyone's hardware budget. And other organizations have turned to caching technology, only to learn that traditional Web site caching solutions address the needs of static content sites but fail to support the dynamic page components associated with personal experiences.
Vignette High Performance Delivery (HPD) is caching technology for Web sites that need to be dynamic, personal and fast. HPD lets organizations deliver fresh, customized content online without either the high cost of hardware or the unacceptable cost of slow site performance. HPD provides a unique, integrated combination of real-time caching and intelligent cache management capabilities. HPD is designed for organizations with high traffic, content-centric sites that want to improve dynamic Web site scalability and performance, while potentially reducing costs.
HPD is a part of the Vignette Web Experience Platform, a scalable enterprise foundation that helps some of the world's premier online brands manage and deliver content. When coupled with the technologies in this proven foundation, HPD lets organizations significantly increase the overall complexity and volume of their Web site pages without the traditional corresponding increase in resources required to deliver such pages.
HPD helps organizations avoid hardware investments by employing a unique caching strategy. HPD can understand the page structures and content dependencies within a site. It takes advantage of the fact that sites are content-driven – and that have page elements that are specific to a user and belong to a known fragment of a page – offer opportunities for caching.
Site administrators who are already comfortable with the Vignette user interfaces don't require a lot of training to leverage HPD, because the product lets site administrators alter caching policies from within the existing user interface. Site administrators can designate regions on a page and apply a caching strategy that allows static content to be fully cached, dynamic content to be refreshed on occasion, and personalized content to be fetched with every page request. If a personalized page region such as a bookmark portlet needs to be rendered as part of a page, it no longer involves re-rendering the whole page. It only requires re-rendering of the bookmark portlet itself; which is a simpler, faster and less costly transaction.
HPD is an innovative solution that helps address the following challenges faced by many organizations:
- It helps control the cost of a sophisticated Web experience. HPD helps enable lower page processing time and increase page delivery throughput.
- It enables improved site response times. HPD can dramatically improve response times for complex dynamic pages.
- It helps ensure that end users get fresh content. HPD is designed to serve up the most current content including links, lists and queries to provide a rich and relevant user experience.
- It reduces the impact of unplanned and planned site outages. HPD's optional Web tier caching allows the delivery of cached pages during planned or unplanned application server down time.
- It reduces developer and IT involvement in the delivery of a great online experience. HPD puts the delivery of dynamic, transactional and personalized page components in the hands of site administrators, which helps to further reduce costs and system complexity.
HPD has a clean, component-based architecture that is open, allowing for integration with third party tools and Web applications. HPD's deployment is streamlined through its conformance to J2EE standards and support for leading J2EE application servers.
HPD is fully integrated with Vignette Portal 7.4, Vignette Dynamic Portal Module (DPM) 7.5 and Vignette Dynamic Site Module (DSM) 7.5.
