Three Approaches to Remote Access for Business Applications
When staff need to access Tally, Busy, or other Windows applications from outside the office, three infrastructure approaches exist. The choice affects reliability, IT overhead, security posture, and cost — in significantly different ways for each option.
Option 1 — Cloud Server (Recommended)
All applications run on a cloud server. Staff connect via Remote Desktop from any device. No VPN. No office internet dependency. Works from any location with internet — office, home, client site, hotel, mobile data.
How it works: Staff open Remote Desktop → enter server address and credentials → see Windows desktop → open Tally or Busy → work identically to local. Session disconnects cleanly when done. No data on local device.
Key advantage: If the office internet fails, home-working staff are completely unaffected — they connect directly to the data centre, bypassing the office entirely. The server is always available regardless of any single location's connectivity.
Option 2 — VPN to Office Server
A VPN creates an encrypted tunnel from a remote device to the office network. Remote staff connect as if they were in the office, then use Remote Desktop to the office server.
Why it often fails in practice:
- Office internet down = all remote access stops — the VPN destination is unreachable
- Dynamic office IP requires IT reconfiguration every time the ISP changes it
- Hotel and corporate firewalls block many VPN protocols
- SSL certificates expire and break remote access until IT renews them
- 4G mobile data is unreliable for most VPN protocols
- Each new remote user requires IT setup time
Option 3 — Physical Office Only
Staff work only from the office. No remote access infrastructure. Simple to manage but inflexible: GST filing deadlines require physical presence, director oversight requires physical presence, any disruption to office access (power, internet, building closure) stops all work.
Side-by-Side Comparison
| Factor | Cloud Server | VPN + Office Server | Office Only |
|---|---|---|---|
| Works if office internet fails | ✓ Unaffected | ✗ All remote stops | ✗ N/A |
| Works from hotel/client firewalls | ✓ Rarely blocked | ✗ Often blocked | ✗ N/A |
| Works on 4G mobile | ✓ Reliable | ✗ Unreliable | ✗ N/A |
| Adding new remote user | Minutes — account creation | IT setup required | Not applicable |
| IT maintenance required | Zero — fully managed | Ongoing — certificates, IPs | Minimal |
| Data on personal devices | None — server only | Possible data copies | Risk of manual copying |
| Monthly cost | ₹700/user + GST | IT support ₹6k–15k/month | Lowest |
When VPN Is Still Appropriate
VPN to a local server may still be appropriate for businesses with: a very stable office internet connection with a static IP, a well-maintained IT team managing the VPN infrastructure, and staff who connect from predictable locations with known-good internet. For businesses without these conditions — which describes most Indian SMEs — cloud server Remote Desktop is the more reliable and lower-maintenance option.
Frequently Asked Questions
For businesses migrating from VPN to cloud: M A Global Network recommends running both in parallel for 1–2 weeks after migration — confirming everything works on cloud before decommissioning the VPN setup. After the parallel period, most businesses discontinue the VPN as cloud proves more reliable. Running both permanently adds complexity without benefit once cloud access is established.
On a good broadband connection (10+ Mbps) to an Indian data centre, Remote Desktop access to cloud Tally or Busy is nearly indistinguishable from local access. The application and all database operations run on the server — only the screen image travels over the internet. For most accounting operations (voucher entry, report generation, ledger review), the experience is effectively equivalent to local use.
