A company is migrating its on-premises data center to a public cloud environment. They require a dedicated, private, and consistent network connection between their on-premises network and the cloud provider's network to ensure low latency and high bandwidth for critical applications. Which cloud connectivity option should they choose?
- ASoftware-Defined Wide Area Network (SD-WAN)
- BCloud Dedicated Connection (e.g., AWS Direct Connect, Azure ExpressRoute)
- CPublic Internet Gateway
- DInternet-based VPN
Show answer & explanationAnswer & explanation
Correct answer: B. Cloud Dedicated Connection (e.g., AWS Direct Connect, Azure ExpressRoute)
Cloud Dedicated Connections (like AWS Direct Connect or Azure ExpressRoute) establish a direct, private network connection between an on-premises data center and the cloud provider, offering consistent low latency and high bandwidth, bypassing the public internet.
Why the other options are wrong
- A. SD-WAN optimizes traffic over various links (including internet/VPNs) but doesn't provide the dedicated physical layer connection itself.
- C. A Public Internet Gateway connects a VPC to the public internet, not a private connection to on-premises.
- D. Internet-based VPNs use the public internet, which doesn't guarantee low latency or consistent bandwidth.
Cloud Dedicated Connection
A service that creates a direct, private network connection from an on-premises data center to a cloud provider's network, bypassing the public internet.
- Offers consistent high bandwidth and low latency
- Increases security by avoiding the public internet
- Examples: AWS Direct Connect, Azure ExpressRoute, Google Cloud Interconnect
Memory trick: Dedicated Connection: Direct to the Cloud.
