Networking in the cloud isn’t just VLANs. On today’s Datanauts episode we explore the ins and outs of building networks in cloud services such as AWS.
Our guest is Anthony Miloslavsky, a network engineer in the finance industry. He’s been leading his company’s AWS networking efforts and wanted to share what he’s been learning.
The first point to understand? Instead of the layer 2 domains that engineers traditionally work with, public cloud networking is basically all layer 3. The provider presents you with its overlay and gives you tools and services to work with it.
Anthony and the Datanauts explore the basic constructs in AWS networking, including Virtual Private Clouds (VPCs) and security groups, and how these constructs will affect your architectural choices.
They also discuss how your AWS networks interact with the rest of the world, including load balancers and NAT gateways. They also drill into the automation capabilities that are on offer, and how those capabilities could influence your premises infrastructure.
