Popular configuration mechanisms like conf.d pose multiple problems when trying to converge system configuration using configuration management tools. Ish-Shalom proposes five design principles for configuration that prevent those problems. The core ideas being the use of a configuration API and the separation of configurations based on the type of system updates they require.
In a workshop at the Agile Testing Day Netherlands attendants experienced the Dev & Ops and DevOps approaches. An interview with Jaap Schuttevaer about what DevOps can bring to organizations, tearing down the walls between Dev and Ops and advice for organizations that want to apply DevOps.
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.
Gene Kim (moderator), Gary Gruver, Andrew Phillips and Randy Shoup have discussed some of the benefits of microservices in a recent online panel.
Anna Shipman, technical architect at UK's Government Digital Service (GDS), revealed to the QCon London attendees how DevOps permeates their culture. GDS aims to lead the digital transformation of UK's government, "mak[ing] digital services and information simpler, clearer and faster". Its most well known site is GOV.UK, which provides government information and services.
Service-Oriented Architecture (SOA) made us think about breaking up monolithic systems into individual services but also encouraged building producer driven monster services with centralised control. With microservices we are going back to the underlying notions of why SOA made sense, Rebecca Parsons claimed in a presentation at the QCon London conference.
Yuval Yeret is a senior enterprise Agile Coach at AgileSparks. At the upcoming Agile India conference he is talking on good and bad ways to kickstart agile the Kanban way. He spoke to InfoQ about the synergies between Kanban and DevOps.
