Deeply ingrained in our philosophy at Deloitte Platform Engineering is the idea of building solutions by composing services to fit a unique business need. Nothing really new here, people have been talking about "mashups" about "service composition" and "composite applications" for a while and we've seen our customers...

For a recent Mule ESB project we needed to pump out a lot (100+) of ESB service operations. Most of them followed the same pattern: synchronous request-response to a single provider API. With so many similar flows to knock out, our thoughts quickly turned to ways to automate development. How much of our code could we...

A handy addition in XSLT 2.0 is a nice set of date and time format XPath functions. XSLT 1.0 was decidedly lacking in these functions, so you may have used a third-party library such as EXSLT for this purpose. EXSLT offers arithmetic functions on dates and times (still absent in XSLT 2.0) but the XSLT 2.0 offering is...

Transformations between XML and other data structures are quite common when it comes to developing an ESB layer. Mule ESB provides a wide range of choices when it comes to...

Recently we helped a client deploy an on-premises ESB platform based on Mule ESB and Apache ActiveMQ. The platform uses JMS queues between ESB services and adapters to provide load balancing and fault tolerance across active/active Mule servers.

The ESB is a strategic IT asset for our client and so went through...

The IT debates continue - vehemently as ever - about which language, which architecture, which methodology and whether to use any methodology at all. Sometimes it feels like we're stuck in the veritable goldfish bowl admiring the shiny new castle that periodically presents itself. How could everyone be so right and so...

Mashape launched yesterday adding a new API player to the growing arena of API management sites and tools. As the Mashape Blog says "everyone and their dog's are building API's these days" and a number of companies have developed API management systems to cater to both public and private APIs.

API Growth (from...
