A cloud customer is experiencing intermittent network performance issues when accessing their cloud-hosted applications. They suspect the problem lies with the path their traffic takes over the public internet, rather than within the cloud provider's internal network. Which networking solution would provide a dedicated, private connection to bypass the public internet and potentially resolve these issues?
- ADirect Connect / ExpressRoute
- BCloud Load Balancer
- CContent Delivery Network (CDN)
- DVirtual Private Network (VPN)
Show answer & explanationAnswer & explanation
Correct answer: A. Direct Connect / ExpressRoute
Direct Connect (AWS) or ExpressRoute (Azure) are dedicated, private network connections from an on-premises data center to a public cloud provider. They bypass the public internet, offering consistent, high-bandwidth, and low-latency connectivity, which can resolve intermittent performance issues caused by public internet routing.
Why the other options are wrong
- B. A Cloud Load Balancer distributes traffic within the cloud environment; it doesn't address connectivity issues between on-premises and the cloud over the internet.
- C. A CDN caches content closer to users to reduce latency for web traffic, but it's not a solution for general application connectivity issues bypassing the public internet between on-premises and cloud.
- D. VPNs use encrypted tunnels over the public internet, which doesn't bypass the internet itself or guarantee performance improvements.
Dedicated Cloud Connectivity
Services like AWS Direct Connect or Azure ExpressRoute provide a dedicated, private network connection from an on-premises data center to a cloud provider, bypassing the public internet.
- Bypasses the public internet, improving security and performance.
- Offers consistent bandwidth and lower latency.
- Ideal for hybrid cloud environments and large data transfers.
- Requires physical provisioning and typically has recurring costs.
Memory trick: Direct Connect is the private highway to the cloud.
