  1. Solutions Engineering isn’t Dev and it isn’t Ops... Industrial Research

    Business Management Human Resources Government Work Regulated Environments Big Data Applications Cloud Infrastructure R in Production What is there to learn? What are the needs? What are the problems? Solutions Engineers!
  2. What are the problems? 1. Legitimacy How do you get

    R recognized as an analytic standard? How do you make R a legitimate part of your organization and get the resources you need to support it? In many organizations, R enters through the back door when analysts download the free software and install it on their local workstations… Some organizations struggle to standardize on R due to a lack of management and governance around open source software. At the same time, organizations may neglect R on user workstations, thereby increasing security, legal, and operational risks. - Nathan Stephens, R Views 2016
  3. 1. DevOps is a philosophy / set of practices 2.

    Which create new processes for collaboration between Dev and Ops teams 3. There’s nothing new in DevOps A framework for making sense out of common sense
  4. Vicious cycle of mutual resentment and distrust Dev Silo IT/Ops

    Silo THE FEAR “Hey - could you just put this thing in production real quick?” “Uh.. I just deployed this little change, and something might be broken”
  5. SUPER-vicious cycle of mutual resentment and distrust Data Science Silo

    IT/Ops Silo THE FEAR “Hey - I wrote this code using a bunch of open source packages some random person from the internet created … Also, I built a Web App - is that cool?”
  6. Challenges for the R User Organizational • Legitimizing R •

    Working with IT Technical • Experience • Education • Exposure
  7. Shiny in Production Journey Code Profiling Version Control Testing Deployment/Release

    Access/Security Performance Tuning Shared Goal: Shorten the distance between development and production Shared Goal: The improvement of daily work Shared Goal: Reduce the risk of deploying a breaking change
  8. Code Quality and Performance The “Hour-Long-Talk” of Data Products -

    Rambling, Cluttered - Parts that work well - Parts that work not-so well Local Development EDA, Prototyping, Iteration The “Lightning-Talk” of Data Products - Targeted - Elegant - Streamlined - Optimized Production Development
  9. Turn a Prototype into a Production Application Performance Workflow 1.

    Use shinyloadtest to see if app is fast enough 2. If not, use profvis to see what’s making it slow 3. Optimize a. Move work out of shiny (very often) b. Make code faster (very often) c. Use caching (sometimes) d. Use async (occasionally) 4. Repeat!
  10. Testing: Why Test Shiny Apps? • You’ve developed a nice

    app • You want to be confident that it will keep running in the future Things that can change/break a Shiny application • Modifying code • Upgrading the shiny package • Upgrading other packages • Upgrading R • External data source changes or fails Shared Goal: Reduce the risk of deploying a breaking change
  11. Automation! • I don’t want to remember to run this

    testing procedure • I don’t want to have to assure someone from IT that I ran it • I certainly don’t want to hand the job off to them GIVE IT TO THE MACHINES Shared Goal: The improvement of daily work
  12. Shared Goal: Shorten the distance between development and production ADVOCATE

    FOR A SANDBOX PUBLISHING ENVIRONMENT B. User Acceptance Testing A. Automated Snapshot Testing
  13. • Deployment is any push of code to an environment

    (test, prod) • Release is when that code (feature) is made available to users Application-based release patterns vs. Environment-based release patterns DevOps Learning: Decouple deployment from release
  14. The DevOps Handbook 1. Accelerate Flow - Make work visible

    - Limit Work in Progress (WIP) - Reduce Batch Sizes - Reduce the number of handoffs - Continually identify and elevate constraints - Eliminate hardships and waste 2. Utilize Feedback - See problems as they occur - Swarm to solve problems and build new knowledge - Keep pushing quality closer to the source - Enable optimizing for downstream work centers 3. Learn and Experiment - Enable organizational learning and a safety culture - Institutionalize the improvement of daily work - Transform local discoveries into global improvements - Inject resilience patterns into daily work Three principles form the underpinnings of DevOps:
  15. Start by answering some questions… - What is a Shiny

    Application? - Who is the audience? - What is your service level agreement definition? (SLA) - What does your analytic architecture look like today? - What are your goals for evolving this architecture? - How will monitoring be handled? - Who is responsible for maintenance? Make work visible, Define shared goals, Build a checklist, Iterate Empathetic Communication is Challenging
  16. Production is... CUSTOMER/USER FACING - Ready to use - Software

    that end users are using - An app that is live and available to the end user - Apps on our production server are available to our clients - Client facing Credibility AT SCALE - Scaled to a larger audience - Bulletproof, scalable, fails predictably - Live to 1000 of users with production vehicle data SERVICE LEVEL AGREEMENTS - Required for mission-critical operations; downtime affects the ability to serve customers - Deployed for end users to have continual access without performance issues ENVIRONMENTAL REQUIREMENTS - An area where validated applications are deployed in a locked down environment - The main part of a company that handles all process - Application or system operates effectively without much maintaining effects - A server or environment that runs the “final” applications that your ultimate end-users (often external customers) use to get stuff down DOCUMENTATION - TESTING & MONITORING - Creating apps that can reach a wider audience and are deployed/tested in a consistent manner - Running in a way that is stable to use, documented and monitored
