The document discusses the integration of DevOps practices within the IoT domain, emphasizing the collaboration between development and operations to adapt to changing market demands. It highlights the historical conflicts between developers and operations and advocates for shared objectives to enhance service quality. Key themes include the importance of automation, continuous integration, and the shift towards microservices architecture in IoT applications.
IoT to Cloud the DevOps Way
- 1. IoT to Cloud, the DevOps Way Development at Web Scale on Web Time Mark Heckler Principal Technologist & Developer Advocate Pivotal Software, Inc. www.thehecklers.org @MkHeck
- 2. @MkHeck Agenda • Define “DevOps” • History and perspective • Why DevOps? Why for IoT in particular? • Digging In • IoT: Matches, Misses, & Adaptations • Walkthrough/Demo/Live Discussion • Summary
- 3. @MkHeck What IS It? Simply stated: • Development (Dev) • Operations (Ops) • Dev + Ops == DevOps
- 5. @MkHeck Historically Opposed Due to Conflicting Objectives • Developers’ sole reason for being: drive change • Better support organization’s objectives • Hopefully increasing funds available to organization in the process • Market/field isn’t immutable; failure to adapt is death
- 6. @MkHeck Historically Opposed Due to Conflicting Objectives • Operations’ primary objective: maintain expected level of service • Risk/reward balance inverse of developers • Change is a very real threat to an ops org • “Don’t touch” policies can take many forms
- 8. @MkHeck Why Mess With It? • “If it ain’t broke, don’t fix it.” • But it IS broken… • Time == Money • At Stake: SURVIVAL
- 9. @MkHeck –W. Edwards Deming “It is not necessary to change. Survival is not mandatory.”
- 10. @MkHeck –Steve Jobs (1995) “Software is infiltrating everything we do these days. In businesses, software is one of the most potent competitive weapons.” –Marc Andreessen (2011) “Software is eating the world.” –Jeff Immelt, GE (2015) “…every industrial company has to be a software and analytics company.”
- 11. @MkHeck “Silicon Valley is coming. There are hundreds of startups with a lot of brains and money working on various alternatives to traditional banking… We are going to work hard to make our services as seamless and competitive as theirs.” –Jamie Dimon, CEO of JP Morgan Chase & Co, 2015 letter to shareholders
- 12. @MkHeck Bring Developers and Operations Together • Shared Objectives • Shared Pain • Shared Reward
- 13. @MkHeck –Mel Conway, 1968 “Any organization that designs a system (defined broadly) will produce a design whose structure is a copy of the organization’s communication structure.”
- 14. @MkHeck –Werner Vogels, Amazon (2006) “Giving developers operational responsibilities has greatly enhanced the quality of the services, both from a customer and a technology point of view. The traditional model is that you take your software to the wall that separates development and operations, and throw it over and then forget about it. Not at Amazon. You build it, you run it. This brings developers into contact with the day-to-day operation of their software. It also brings them into day-to-day contact with the customer. This customer feedback loop is essential for improving the quality of the service.”
- 15. @MkHeck Why is this Important?
- 16. @MkHeck Keep CALMS and DevOps
- 17. @MkHeck Culture Sometimes when people see gourmet food and ping pong tables, they only see the most superficial aspects. They wonder out loud if people won’t abuse the opportunity. If people can’t be trusted with food and ping pong, what makes you think they can be trusted with delivering the future of a company?
- 18. @MkHeck Automation (CD) –Noah Sussman, Etsy “If pushing is easy enough, then pushing a fix will be too.” “Instead of fearing change, we get people used to it. The risks change, but we take steps to address the risks. It’s a different way of developing software.”
- 19. @MkHeck Lean (Microservices) Loosely coupled service oriented architecture with bounded contexts If every service has to be updated in concert, it’s not loosely coupled! If you have to know about surrounding services you don’t have a bounded context.
- 20. @MkHeck Again: Why is this Important?
- 21. @MkHeck IoT: Matches • Focus upon people and change • Continuous Integration • Continuous Delivery • Measurement • Collaborative environment
- 22. @MkHeck IoT: Misses • CI/CD for extreme endpoint (often “dumb”) devices • Direct focus upon end user (with exceptions)
- 23. @MkHeck IoT: Adaptations • Infrastructure as Code • Microservices
- 24. Time for a Walk(through)
- 26. @MkHeck An Example of an Enabling Platform: Cloud Foundry One consistent API • On-premises • Public cloud • Any provider
- 28. @MkHeck Summary • DevOps isn’t NoOps, HugOps, or ToolOps, but… • Roles of Devs, Ops do change • Trust & collaboration a requirement • Tools enable everything (rapidly, repeatably) • Already “doing DevOps”? Adapt for IoT • No? IoT provides overwhelming incentive to do so
- 30. @MkHeck –Derek Sivers, founder of CD Baby “The most brilliant idea, with no execution, is worth $20.”
