To minimize network latency and improve content delivery for users in Europe, the best solution is a content delivery network. Amazon CloudFront specializes in caching content in multiple locations worldwide, known as edge locations, closer to end-users to ensure low latency and fast data transfer. Using this service would allow the company's European customers to access the content more quickly. Choosing a VPN connection or establishing a Direct Connect link would primarily address concerns of a secure, reliable link between an on-premises data center and the cloud provider, not improving customer-facing content delivery. Route 53 provides DNS services, which can route user requests to endpoints more efficiently but does not directly address the issue of latency or caching content closer to the users.
