Secure On-Premises to AWS Connection Within One Week?

Why the Answer Is Correct

AWS Site-to-Site VPN is correct because it creates an encrypted IPsec tunnel between an on-premises customer gateway and an AWS virtual private gateway or transit gateway over the public internet. It is a fully managed AWS service, so there is no physical circuit to order, no cross-connect to schedule, and no carrier coordination that would consume the one-week window. As alokdixit2006 noted, it uses "IPSec tunnels" to provide a secure path between the data center or branch office and AWS resources. This makes it the only listed option that delivers the required security and can realistically be operational within days.

Why the Other Options Are Wrong

AWS Direct Connect offers a dedicated private connection, but provisioning involves AWS Direct Connect locations, cross-connects or hosted connections, and often third-party carriers, so it routinely takes weeks or months rather than one week. Amazon VPC is a virtual network that hosts AWS resources; it is not itself a hybrid connectivity service and would still need a VPN or Direct Connect to reach on-premises. An edge location is part of CloudFront's content delivery network, not a secure tunnel for extending an on-premises network into AWS. None of these alternatives solves both the security and the one-week timeline.

Community Comment Notes

The community consensus is strongly behind Site-to-Site VPN. As lunatik observed, the key phrase is "1 week" and Direct Connect needs more time because it involves multiple parties and configurations. ShaiTay likewise selected it as "best for the short set up time," while komorebi simply confirmed the answer. Alokdixit2006 added the useful technical detail that the service uses IPsec tunnels, reinforcing why it satisfies the secure-connection requirement without a long procurement cycle.
