### Concurrency and Burgers

This idea of **asynchronous** code described above is also sometimes called **"concurrency"**. It is different from **"parallelism"**.

**Concurrency** and **parallelism** both relate to "different things happening more or less at the same time".

But the details between *concurrency* and *parallelism* are quite different.

To see the difference, imagine the following story about burgers:

  * Multiple fixes to avoid hitting AWS rate limits, and to throttle if we do
  * Support for the EC2 Container Registry (currently in us-east-1 only)

With kube-up:

  * Automatically install updates on boot & reboot
  * Use optimized image based on Jessie by default
  * Add support for Ubuntu Wily
  * Master is configured with automatic restart-on-failure, via CloudWatch

## CRUD utils

Now let's see the file `sql_app/crud.py`.

In this file we will have reusable functions to interact with the data in the database.

**CRUD** comes from: **C**reate, **R**ead, **U**pdate, and **D**elete.

...although in this example we are only creating and reading.
