Ingress
ELI5 — The Vibe Check
Ingress is data coming INTO the cloud from outside — the opposite of egress. Cloud providers almost always let you send data IN for free (ingress) because they want your data on their platform. The exit (egress) is where they charge you. It's like a roach motel for your data.
Real Talk
Ingress refers to inbound data transfer entering a cloud provider's network from the public internet or other external sources. Ingress is typically free or very low cost across major cloud providers. In Kubernetes, 'Ingress' also refers to an API object that manages external HTTP/HTTPS access to services within a cluster.
