Cloud-based development, delivery, and deployment environments are the future of IT operations. Thomas Stiehm shares the hard-learned lessons of setting up and running cloud-based solutions that implement DevOps for geographically distributed agile projects. Thomas describes how to best leverage the cloud to enable your teams to use it effectively. Learn why cloud software delivery is different from traditional software delivery environments, and how to optimize your platform and team to get the most out of the cloud. Geographically-distributed software delivery teams are now the norm for large projects, and the cloud is a perfect enabler to level the playing field for your distributed teams and to give them all the same ability to achieve high productivity. Since the road to the cloud isn’t always paved, learn many of the trade-offs that must be made to implement cloud-based delivery and discover the situations that will derail a move to cloud-based development.

  4. 4. Cloud-based Cloud Computing - In its essence, Cloud Computing is a massive distributed computing model consisting of three tiers: p g g infrastructure, platform and services, and is about using swarms of computers to deliver unprecedented computing power to people and organizations across the globe. Cloud computing isn't a new technology nor a new architecture... it s architecture it's a new delivery model 1 model. 1. http://www.mkpress.com/CloudReading © Copyright 2012 Coveros, Inc.. All rights reserved. 3 DevOps DevOps – A combination of Development and Operations, it is a software development method that stresses communication, collaboration and integration between software developers and Information Technology (IT) professionals. DevOps is a response to the interdependence of software development and IT operations. It aims to help an organization rapidly produce software products and services.1 1. http://en.wikipedia.org/wiki/DevOps © Copyright 2012 Coveros, Inc.. All rights reserved. 4
  5. 5. Distributed Agile Projects Distributed Agile, as the name implies, is a model in which projects execute an Agile Methodology with teams that are gy distributed across multiple geographies.1 1. .

SalesForce.com – Platform-as-a-Service (PaaS) vendors that give developers the tools to build and host using specific frameworks or services, ex. G i Google Apps Engine l A E i – Infrastructure-as-a-Service (IaaS) vendors that offer access to raw storage and computing resources, ex. Amazon EC2 © Copyright 2012 Coveros, Inc..

Features of Cloud Services Cloud Provisioning Dynamic Computing Infrastructure Self-Service, Self-Managed Platforms Programmatic Control of Server Resources Internet Access Geographic Distribution © Copyright 2012 Coveros, Inc.. All rights reserved. 7 Lessons Learned: The Project The technology parts are challenging The people parts are hard, often really hard Automate everything as early as possible Automation is software, treat it like the application code – – version – review – test Test everything, including your automation As you learn error and failure conditions, automate dealing with them © Copyright 2012 Coveros, Inc.. All rights reserved. 8
  7. 7. Lessons Learned: The Vendor The right cloud vendor can make or break you. Pick one that meets your needs, skip any that don’t p y provide real cloud services. There is no perfect cloud platform, they all have problems. If you pick a cloud provider that expects things to be done their way, do it their way. If you pick a cloud provider that offers extra i k l d id h ff services that induce lock-in, consider using their extra services but think about it a lot. It could work better than rolling your own. © Copyright 2012 Coveros, Inc.. All rights reserved. 9 Things to Expect Expect to do a lot of learning, teaching, hand holding and pushing for new practices Expect to explain things multiple times: issues, processes, practices, and priorities at multiple levels: developers, architects, testers, BAs, Project Managers, Product Managers, Directors, VPs, the client, and end users Expect confusion, rejection and clinging to old practices Expect to do a lot of expectation setting and resetting © Copyright 2012 Coveros, Inc.. All rights reserved. 10
  8. 8. Things to Expect Expect to make ultimatums and to get strong pushback to those ultimatums Expect to fail the first time with almost time, everything you put in place Expect everything to take longer than you planned Expect the expectation of immediate results and payoffs, work your way through l d ff k h h them Expect your detractors to take credit when things, in the end, succeed © Copyright 2012 Coveros, Inc.. All rights reserved. 11 How to Best Leverage the Cloud Understand your system, application and organizational requirements Pick a Service Model – SaaS – IaaS – PaaS Pick a Vendor that suits your requirements, service model and budget Train your team on the vendors technology and service model © Copyright 2012 Coveros, Inc.. All rights reserved. 12
  9. 9. Live in the Cloud Use Cloud-based service to communications: – Text (IM and Email) – Voice – Video – Collaboration – Source Code Management – Code Review – Project Management Software Using Cloud services helps to make people around the country or globe equal members of the team and reduces location bias © Copyright 2012 Coveros, Inc.. All rights reserved. 13 Living in the Cloud Example Requirements gathering using Cloud resources such as Google Docs and Sites Task Management in the Cloud using Trello Project Management in the Cloud using VersionOne Development in the Cloud using EC2 Development Resources in the Cloud using GitHub Testing in the Cloud using EC2 Deployment and OPS in the Cloud using EC2 © Copyright 2012 Coveros, Inc..

  10. 10. Enabling Distributed Teams Use Cloud-based technologies to avoid second class team syndrome Face to Face team building g – In person is best – Video is better than nothing – If your locations don’t “know” each other, they won’t trust each other – Phone calls aren’t enough aren t Make sure that all locations have equal opportunities for – Advancement – Interesting Work © Copyright 2012 Coveros, Inc.. All rights reserved. 15 What are the Advantages? Ability to focus on your core value Flexibility Time t market Ti to k t Speed of development Less up front cost Proven platforms Scalability or at least scalability patterns No hardware infrastructure to manage Geographic distribution Cheaper? © Copyright 2012 Coveros, Inc..

  11. 11. Cloud Provisioning Most people think of dynamic production scaling when they think of Cloud provisioning But it also means: – Full setup and tear down of test environments – Creation and disposal of development and test environments based on need – Scaling development and test environments to fit the task, so if you want to do performance testing on a duplicate of your production environment, you can, without having those resources in-house © Copyright 2012 Coveros, Inc.. All rights reserved. 17 Programmatic Control Programmatic control of self-service APIs allows your team to fully automate setting up and tearing down resources for: p g – Dynamic scaling of production resources – On-demand creation of development and test resources, sized to fit the immediate needs – Fully automating the development, test, y g p , , and deployment life cycle Automation is not magic. You have to work at it, maintain it, and manage configuration data. © Copyright 2012 Coveros, Inc.. All rights reserved. 18
  12. 12. Self-Service API Automated everything – Development Setup – Test Setup – Running Tests – Populating Application Data/Test Data – Builds – Deployment – Monitoring/Scaling – Reporting Be able to rebuild your entire environment, including your development, test tools and servers automatically © Copyright 2012 Coveros, Inc.. All rights reserved. 19 Cloud vs. Traditional Development Vendor lock-in - Your application code will be tied to the vendor's service offering, you will be integrating their API and Services into g g your code You are dependent on their development and testing, resources and practices You don’t have the same level of control, with SaaS and PaaS you are plugging your software extension into the vendor’s system To get the advantages of cloud platforms you must work within their constraints, using their tools or your tools their way © Copyright 2012 Coveros, Inc.. All rights reserved. 20
  13. 13. Trade-Offs Loss of control: You no longer control the infrastructure. It can go down or change and y you have to deal with it and live with it. The cloud vendor has a different set of priorities than you. You don’t have to worry about infrastructure. SaaS gets you started very quickly, but it limits how you can grow. li i h PaaS simplifies your choices but locks you in IaaS can be like a CoLo arrangement with more control and all of the responsibility. © Copyright 2012 Coveros, Inc.. All rights reserved. 21 Derailments Picking the wrong vendor Picking the wrong service model No automation: development, deployment test or infrastructure Physical data-center operator mentality No access VM consoles or VM API Staff th t i d St ff that is adamantly against change, tl i t h management that doesn’t support change Application requirements that don’t fit within the vendor’s framework © Copyright 2012 Coveros, Inc.. All rights reserved. 22
  14. 14. How to Begin Create a plan, short term, near term, long term. You are going to get it wrong, keep adjusting and resetting expectations. Focus on priorities. Base priorities on business values, however you define that. If you don’t show value, you will fail in the long run. Start simple and get more sophisticated as you go. You are going to have to refactor your work/process/practices anyway as you don’t know what you are doing at first, so rework/refactoring is unavoidable. © Copyright 2012 Coveros, Inc.. All rights reserved. 23 Work in small, quick steps, adjust your strategy and tactics around things that work. Fix pain points. Focus on fixing the pain points of the people that have the most to gain, prove the value to them and their direct management. Get key stakeholders and influencers on your side. Sh id Show them h h how lif will b b life ill be better for them doing things your way. Some people will reject the new way of doing things. Route around them and eventually the organization will leave them behind. 24 How to Begin © Copyright 2012 Coveros, Inc.. All rights reserved.
  15. 15. Reasons not to use the Cloud You have a stable Application with little new requirements You have an infrastructure that meets your needs You need to have complete control over your entire environment and have little risk tolerance You h Y have to b d budget exact resources, and d allowing for flexibility and dynamic computing isn’t allowed There isn’t any benefit to changing your process and practices, for now © Copyright 2012 Coveros, Inc..
