5. Vagrant A tool for making VMs on your laptop
6. Cloud Someone else maintains the physical hardware
7. AWS Amazon Web Services, 
 a cloud provider
8. EC2 Elastic Compute Cloud, AWS makes you VMs
9. S3 Simple Storage Service, AWS stores your files
10. CloudFormation Create and manage AWS stuff using YAML files instead of clicking in the web UI
11. Terraform Create and manage things on lots of clouds without clicking in the web UI
12. GCE Google Cloud Engine, AWS but by Google
13. Azure AWS but by Microsoft (yes, you can run Linux)
14. OpenStack AWS except you also run the physical hardware too
15. Container A process running with a bunch of security options
16. Container Image A tarball containing the files a container will see (and some metadata)

21. Docker Compose Small, complex thing for managing a few containers
22. Orchestration Coordinating multiple containers together along with storage and networking they need
23. Resource Scheduling Working out which server to run a container on given multiple options
24. Serverless Tool(s) for making web apps/APIs with less boilerplate
25. CI Continuous Integration, except not that. Running tests automatically on every commit
26. CI Pipeline Dividing tests up into multiple groups and then chaining them together
27. Jenkins Popular (and often infuriating) CI tool
28. Travis Also a popular CI too, but you don't have to run it yourself and free for open source
29. CD Continuous Delivery or Deployment, if the tests pass then it gets deployed
30. Big Data Running queries against more data than will fit on one server (~>= 10TB)
31. Hadoop Popular suite of 
 tools for Big Data
32. Spark Hadoop component used for running the fancy queries
33. ETL Extract Transform Load, a common Big Data query pattern
34. InfoSec Information Security, keeping your data safe
35. Black Hat Using InfoSec for evil
36. White Hat Using InfoSec for good
