Scalability + Edge Computing + VPCs

Vertical scaling

increases the capacity of existing servers

Horizontal scaling

adds more servers to a pool of clustered servers

Edge computing

places some processing power on the remote sesnors, allowing them to preprocess data before shipping it back to the cloud.

Fog computing

uses IoT gateway devices that are located in close physical proximity to the sensors. The sensors themselves don’t necessarily have processing power, but they send data to their local gateway that performs preprocessing before sending the results in the cloud

Virtual Private Clouds (VPCs)

achieve segmentation in cloud environments

Cloud providers also offer VPC endpoints

that allow the connection of VPCs to each other using the cloud provider’s secure network backbone

Cloud transit gateways

extend the VPC model even further, allowing the direct interconnection of cloud VPCs with on-premises VLANs for hybrid cloud operations
