At QCon London 2015 Phil Calcado shared lessons learnt from SoundCloud’s move from a monolithic to microservices architecture, and stated that the core requirements for building a microservice platform include developing capabilities for rapid provisioning, basic monitoring and rapid application deployment.
Microservices are conceptually too big; they conflate optimizing for organisational and technical factors, but solutions to problems of each type may not fit together very well, Phil Wills, senior architect at The Guardian, explained in a presentation at the QCon London conference promoting thinking about independent services and single responsibility applications, rather than microservices.
At the last QCon London, Michael Brunton-Spall, Technical Architect at the UK's Government Digital Service, expressed his views on how DevOps patterns are crucial to successfully operate microservices. Brunton-Spall identified the key ingredients to identify a microservice, explained how to build your first microservice and the necessary tools and practices to manage an ecosystem of microservices.
At QCon London 2015, Dave Farley proposed that although the state of software development has been suboptimal in the past, studies are revealing that the implementation of continuous delivery leads to considerable improvement. Farley stated that continuous delivery changes the economies of software development, and provides more rapid business idea validation and reduced defect rates.

Jez Humble has stated that current software delivery practices are not optimised to create valuable software, and three issues must be addressed in order to enable innovation. First, the traditional project model is unsuitable. Second, the entire organisational value stream must be addressed. Third, the problems are rooted in process and culture, not organisational structure or tooling.
In too many cases agile is failing to deliver on its promise says Steve Holyer. At the OOP 2015 conference Steve explained how we can choose the rewards and benefits that we want to get out of agile development and plan the investments to achieve them. He presented the agile fluency model and explored a solution-focused approach for organization to find their path in adopting agile.
