Question network architects actually ask: which cloud connectivity method reduces latency without adding operational overhead?

Short answer: it depends on what you're routing around — public internet variability or private path control.

The three methods, side by side

Internet-based connectivity

• Cheapest to stand up

• Best-effort routing across shared infrastructure

• Latency and jitter vary with congestion — outside your control

VPN over public internet

• Adds encryption, not path control

• Still subject to internet routing behavior

• Fine for low-priority traffic, risky for production workloads

Layer 2 private connectivity

• Direct, point-to-point handoff between endpoints

• Removes public-internet variability from the path

• Requires design and ongoing operation — the tradeoff for control

Where teams get stuck

Choosing a method is the easy part. Operating it is where cloud connectivity breaks down:

• SLAs split across vendors, with gaps at the handoff

• Portal-based support that can't coordinate across providers

• Slow resolution when a fault crosses a provider boundary

None of that shows up in a comparison chart — it shows up during an outage.

Practical guidance for architects

1. Match the method to the workload — not every path needs Layer 2

2. Document handoffs and ownership before provisioning, not after an incident

3. If you're under HIPAA or SOC 2 scrutiny, build audit-ready documentation into the connection from day one, not retroactively

This maps to real operating patterns seen across healthcare and enterprise environments running Google Partner Interconnect, AWS Direct Connect, Azure ExpressRoute, and the Equinix ecosystem — where the failure point is almost always the boundary between providers, not the method itself.

For teams ready to move off best-effort routing, see how managed Layer 2 connections remove the provider handoff problem entirely.

Talk to an engineer before your next audit — or your next outage — forces the conversation.
