AI with Watson

AI includes

• text to speech
• speech to text
• visual recognition
  • can find a picture in a video
  • tag the people ages
  • upload a photo can recognize it

IBM Bluemix

• a service inside Bluemix: Watson VR
  • create a VR instance, each with a APIKey
  • can recognize 250 photos/day free of charge

Python

• favor of many data scientists, since easy to use
• installed packages by pip (python install package)
• e.g. pip install watson_developer_cloud
• IDE Jupyter, can run code dynamically in a document

Link:

• Cognitive class
• Watson Visual Recognition
• IBM's Watson Supercomputer Destroys Humans in Jeopardy
• TJBot

Building an AI-powered application in 30 minutes

Aim: Democratized AI - make it popular for everyone

Microsoft AI components

• Bot framework
• Cognitive toolkit/service
• ...

Classifier

• e.g. EA1 team, car, Sushi, ...
• upload a zip of photos to train the AI

Microsoft Azure Machine Learing Studio

• https://studio.azureml.net/
• login: [email protected]
• experiments + data --> predictive web service
• Telco Customer Churn, use this AI to build a churn model enables you to predict the customers that will churn (leave).

Cloud Native Applications

Agile: welcome change

Conway's Law

Any organization that designs a system (defined more broadly here than just information systems) will inevitably produce a design whose structure is a copy of the organization's communication structure.

Cloud native app

• not implies it is running on the cloud, but
• follows certain process/practices, e.g. CI/CD, DevOps, ...
• automate everything if possible
• fulfill twelve-factor app's criteria

DevOps

Pets vs Cattle (metaphor of cloud scaling)

• with name vs. no name
• Disposability: repair vs. replace
• ...

XaaS

• SaaS: VM + OS + DB + security + App, e.g. Gmail, Dropbox
• PaaS: VM + OS + DB + security, but no app
• IaaS: VM only, no OS

The Twelve-factor App

1. Codebase: One codebase tracked in revision control, many deploys
2. Dependencies: Explicitly declare and isolate dependencies
3. Config: Store config in the environment (even stored in external properties file is not enough)
4. Backing services: Treat backing services as attached resources
5. Build, release, run: Strictly separate build and run stages
6. Processes: Execute the app as one or more stateless processes
7. Port binding: Export services via port binding
8. Concurrency: Scale out via the process model
9. Disposability: Maximize robustness with fast startup and graceful shutdown
10. Dev/prod parity: Keep development, staging, and production as similar as possible
11. Logs: Treat logs as event streams
12. Admin processes: Run admin/management tasks as one-off processes

Greenfield project

• new project, no need to integrate with legacy systems, without previous projects constraints

PCF-demo in Cloud Foundry

• Try PCF on the Public Cloud
• run.pivotal.io
• GitHub

cf env pcfdemo -m 100    // add CF memory for pcfdemo
cf push pcfdemo        // deploy app
cf app pcfdemo        // check app status
