EC2 vs VPC
EC2 (Elastic Compute Cloud) and VPC (Virtual Private Cloud) both come up in technology conversations and get confused. Here's the plain-English difference, side by side, so you can use each one with confidence.
The key difference: EC2 refers to elastic compute cloud, while VPC refers to virtual private cloud — they describe different things even when they show up in the same sentence.
EC2 — Elastic Compute Cloud
Amazon's on-demand virtual server product — the original cloud primitive. EC2 instances are the raw compute beneath most managed AWS services.
VPC — Virtual Private Cloud
A logically isolated network within a public cloud provider. A VPC is your perimeter — everything inside it can talk freely; everything outside has to be explicitly allowed in.
When to use EC2
Reach for "EC2" when the conversation is specifically about elastic compute cloud. Amazon's on-demand virtual server product — the original cloud primitive. EC2 instances are the raw compute beneath most managed AWS services.
When to use VPC
Reach for "VPC" when the conversation is specifically about virtual private cloud. A logically isolated network within a public cloud provider. A VPC is your perimeter — everything inside it can talk freely; everything outside has to be explicitly allowed in.
