AWS: S3 and Lambda

Describe “The Cloud”

Instead of one server managing all back-end functions and processes, each function/process is handled by a separate server.

What is a container (as it relates to computers and servers)?

A compute environment that contains everything needed to function on its own.

What is auto-scaling?

A service that monitors your applications and automatically adjusts compute resources to maintain steady, predictable performance at the lowest possible cost.

What is bandwidth?

The maximum rate at which data can transfer from one machine to another.

How do cloud providers compute service costs?

Based on usage.

Document the following Vocabulary Terms

• Server Instances: a virtual machine which runs our workloads in the cloud.

• Containers: A compute environment that contains everything needed to function on its own.

• Cloud Services: come from cloud providers.

• Cloud Architecture: how computing environments are designed.

• AWS: provides on-demand cloud computing platforms and APIs to on a metered pay-as-you-go basis, with a basic abstract technical infrastructure and distributed computing building blocks and tools.

• EC2/Beanstalk vs Heroku: Heroku’s pricing takes exponential price jumps as one adds common additional features such as auto-scaling. AWS pricing is fairly linear. In contrast, Heroku is generally simpler to get up and running. AWS has a fairly steep initial learning curve.
