AWS service that creates a dedicated, private network connection from your office or data center directly to AWS. Like having a private highway built just for your company's traffic, bypassing the public internet entirely.
A financial firm uses Direct Connect to transfer sensitive trading data between their data center and AWS with guaranteed bandwidth and security.
All provide private, dedicated (or partner-provisioned) connectivity from on-premises networks to the cloud, improving bandwidth consistency, latency predictability, and avoiding the public internet. They differ mainly in port speeds, partner ecosystems, and routing/attachment models.
