In this talk, Donnie shared what he's seen and what he predicts for the future of how we build and deploy applications to generate business value. You'll hear buzzwords like DevOps, Docker, and microservices used in ways that actually make sense (for a change), see real-world examples of companies that have succeeded at the leading edge, and learn how approaches like the one taken by HashiCorp's Terraform (by the authors of Vagrant) will be critical to the future of how we build software.

Editor's Notes
- Today we’re going to dig deep into the technology, and specifically one of the hottest technologies of the past year – containers.
- 0 talks at Glue last year, 12 this year 1 proposal at OSCON last year, 30 this year Intro myself and credibility re containers/microservices
- Overall business goals
- “Does your company struggle with increased demands for shorter release cycles, with business managers expecting weekly, daily or even hourly releases and updates?” 63% overall
- Cathedral, indulgences to bazaar Open source, cloud, DigitalOcean Shadow IT: IT as service provider, as vendor
- Future is two years out App dev is 7.8% of workloads, ranked #5 (highest is email/collab at 15.9%) How do you get them to choose your offering? … But how are they building this?

- Languages, databases, frameworks … What’s driving the way we build technology?
- OODA loops
- Culture: Collaboration, Sharing Automation: Digital Measurement: KPIs
- Configuration management CFEngine 1.0: 1993
- Release management – quarters to weeks to days to hours Gary Gruver, HP
- Nagios (NetSaint): 1999 Community, UX Keep using cattle metaphor
- The next step in DevOps How do we cope with these demands for agility, scalability, automation, transience?
- VotE shows most orgs are largely moved to virtualization, a minority to automation, few to orchestration/private cloud Vagrant, Packer, Docker
- Windows catching up quickly with DevOps and containers No need to leave the Microsoft half of your environment behind
- Business-defined separations. Bounded context based on cross-organizational empathy. Steve Yegge memo — Amazon must be SOA, or you’re fired.
- DevOps + microservices Bounded contexts, empathy defined DevOps is how you build and run microservices.
- Nomad out of HashiCorp, new competitor to Mesos/Kubernetes Azure Container Service, building on Docker & Mesos. Beta by EOY 2015 Also note PaaS providers moving to containers
- Amazing stuff, great open-source code But hard for the rest of the world to envision becoming like them Any others?
- Launch a multitenant, elastically scalable, componentized cloud integration platform Dynamically launch and run 100s of different demos in AWS Their own customers running hotel kiosks, retail POS
- Worked well: template project, resilience, idempotence, automation, exposing verbs Wrote their own testing library to test consumers Problems: right-sizing, code sharing (inheriting from common git repo and adding files worked)
- The future of service delivery.
