• ✗

  Increase the bandwidth at the remote office

  Why it's wrong here

  Increasing bandwidth primarily enhances the volume of data that can be transmitted over a given period (throughput), not the time it takes for a single packet to travel from source to destination (latency). A 150 ms delay indicates high latency, meaning each network request and response takes a significant amount of time to complete. Adding more bandwidth will not reduce this inherent travel time for individual packets, which is the core issue affecting VDI login responsiveness.

• ✗

  Upgrade the cloud VDI servers to faster CPUs

  Why it's wrong here

  Upgrading cloud VDI server CPUs would improve the processing speed of tasks on the server itself, such as application execution or desktop rendering. However, the described problem is a 150 ms network delay, which is latency between the remote office and the cloud. Faster CPUs cannot reduce the time it takes for data packets to physically traverse the network, making this solution ineffective for mitigating network latency as the primary bottleneck.

  Deploy a local VDI broker or caching server at the remote office

  Why this is correct

  Deploying a local VDI broker or caching server at the remote office directly addresses the impact of high latency by reducing the number of necessary round trips across the WAN. A local broker can handle initial authentication, profile loading, and policy enforcement locally, caching frequently accessed data and minimizing interactions that must traverse the 150 ms link. This significantly speeds up the login process by keeping more operations geographically closer to the user.

• ✗

  Switch to a different cloud provider

  Why it's wrong here

  Switching to a different cloud provider is a drastic and often unnecessary measure that does not guarantee a reduction in network latency. Latency is predominantly determined by the physical distance between the remote office and the cloud data center, as well as the quality of the network path. A new provider might have data centers in different locations, but there's no assurance one would be geographically closer or offer a lower-latency network route to the specific remote office experiencing issues.
