Connecting on-premises networks to AWS Local Zones
For use cases where resources in an AWS Local Zone need to communicate with resources in an on-premises data center in that same metro area, there are two basic approaches. The first is a physical connection via AWS Direct Connect and the second is a virtual connection via a VPN over the public internet. Both approaches have benefits and drawbacks, which must be weighed in light of the requirements and constraints that a given project is operating within.
AWS Direct Connect
AWS Direct Connect is a service that provides dedicated network connections from on-premises environments (such as a corporate data center) to AWS. Instead of using the public internet for AWS data transfer, Direct Connect offers a private, high-bandwidth, and consistent network experience. It often results in reduced network costs and increased bandwidth throughput and provides a more consistent network experience than typical internet-based connections.
