explanation for non-techies**

Imagine you're organizing a large conference and initially planned to have a venue that could accommodate 5,000 attendees. You then consider expanding to a venue that could hold over 20,000 people, thinking it would allow more people to join and make the event more successful. However, after some consideration, you decide not to go through with the expansion because it might not be feasible or necessary at this time.

In the world of IT, a similar situation occurred with Microsoft Intune's Tunnel gateway server. The original plan was to increase the capacity of each server from supporting 5,000 clients to over 20,000. This would have been like moving to a larger venue to accommodate more attendees. However, the decision was made to cancel this plan. This means that, for now, each Tunnel gateway server will continue to support up to 5,000 clients, just like sticking with the original venue size for the conference.

This change might be due to various reasons, such as technical challenges, cost considerations, or a reassessment of current needs. Just as in event planning, where logistics and practicality can influence decisions, similar factors play a role in IT infrastructure planning. The key takeaway is that plans can change based on new insights or priorities, and sometimes sticking with the current setup is the best course of action.
