AWS PrivateLink is now available on Pro and Enterprise

Vercel has extended AWS PrivateLink to its Pro and Enterprise tiers, enabling private network connectivity between Vercel Functions and AWS-hosted services. This removes the need for public internet traversal, which can reduce latency and exposure to potential attacks. The feature targets teams running hybrid architectures where Vercel hosts frontend or serverless logic while AWS manages backend services like databases or internal APIs. Configuration requires enabling Advanced Networking in project settings and specifying the AWS service name and region, which may add setup complexity for teams unfamiliar with AWS networking primitives.

The integration requires the AWS service to accept connections from all AWS principals or explicitly allowlist Vercel’s provided IAM role. This introduces a dependency on AWS-side configuration, which may slow adoption for teams without direct control over their AWS environments. Once configured, Vercel provides a stable hostname for private access, simplifying DNS management but requiring updates to existing code or infrastructure to use the new endpoint. The feature is positioned as an add-on to Advanced Networking, meaning teams must already be using or willing to adopt that tier to access PrivateLink.

Pricing follows a tiered model: the first PrivateLink connection is included with Advanced Networking, but additional connections cost $30 per month each, and data transfer incurs $0.04 per GB. For high-throughput workloads, data transfer costs could accumulate quickly, making this less attractive for teams with tight budgets. The inclusion of the first connection lowers the barrier to trial, but scaling beyond a single service may require careful cost-benefit analysis. Teams should also monitor AWS-side PrivateLink pricing, which is not covered by Vercel’s fees and could add further expense.

The feature’s scope is limited to AWS-hosted services, meaning teams using other cloud providers or on-premises infrastructure won’t benefit. It also requires the target AWS service to support PrivateLink, which excludes some AWS offerings or configurations. For teams already invested in Vercel and AWS, this fills a gap in secure hybrid connectivity, but those with multi-cloud or non-AWS backends will see no immediate value. The documentation suggests compatibility with common AWS services like RDS, Aurora, and S3, but teams should verify support for their specific use cases before committing to the setup.
