# Elastic Compute Cloud (EC2)
|
|
|
|
|
|
|
|
|
|
- Cloud-based or virtual server (virtual machine), basically a hypervisor
|
|
|
|
|
(compare [[zk/Docker_architecture]])
|
|
|
|
|
- It is virtual because you are not responsible for its physical implementation
|
|
|
|
|
- Still needs considerable configuration compared to a serverless
|
|
|
|
|
[[zk/Lambda_programming_model]]
|
|
|
|
|
- Like lambdas has the benefit of easy scaling: you can add compute capacity on
|
|
|
|
|
demand (elasticity)
|
|
|
|
|
|
|
|
|
|
The following needs to be considered:
|
|
|
|
|
|
|
|
|
|
- Naming
|
|
|
|
|
- Application and OS image (known as "Amazon Machine Image"):
|
|
|
|
|
- Which OS you want to use (Linux distribution, Windows, etc)
|
|
|
|
|
- Applications you want pre-installed
|
|
|
|
|
- Block device mapping
|
|
|
|
|
- Instance type an size (basically the type of processor and how powerful you
|
|
|
|
|
want it to be)
|
|
|
|
|
- An encrypted key-pair for login
|
|
|
|
|
- Your network (typically managed via Amazon VPC (Virtual Private Cloud)) and
|
|
|
|
|
network security
|
|
|
|
|
- Storage: size and type (eg. GP3)
|
|
|
|
|
- Location and latency
|
|

|
> EC2 is more expensive copared to serverless options. Accordingly it is better
|
|
|
|
|
> to run smaller servers (in terms of processor and memory) at higher capacity
|
|
|
|
|
> than larger servers under-capacity.
