Day three of the QCon London conference featured John O'Hara's keynote on Advanced Message Queuing Politics, detailing the evolution and importance of message-oriented middleware like AMQP. He described a significant bank's experience in developing middleware that ultimately fueled investment in AMQP. O'Hara emphasized the challenges with inconsistencies in middleware standards over the years and highlighted the continued relevance of AMQP 1.0 as the current protocol standard. His insights reveal the complexities and costs associated with inter-business and intra-system connections in modern bank operations.
By the 1990s, middleware was considered arcane to keep up with the scale at which banks had been operating. The banks would often write their own middleware.
O'Hara stated that "inter-business and intra-system connections are a major source of complexity and cost," highlighting the difficulties in managing system connections.
Despite being released in October 2011, the AMQP 1.0 protocol still remains today's standard, underscoring the challenge of creating universal standards in technology.
Creating a universal standard can be challenging. In 2002, there were 14 standards, and O'Hara stated that we are all too familiar with this situation.
