I've been evaluating the shift from traditional VPNs to SSE for a new internal tooling API. The vendor whitepapers are predictably full of abstract "security transformation" slides, but I need to understand the concrete architectural changes and performance implications.
Where should a backend engineer start to get practical, implementation-focused knowledge? I'm particularly interested in:
* The actual traffic flow for a Zero Trust Network Access (ZTNA) connection versus a VPN tunnel. I want to see packet-level diagrams or API call sequences.
* The impact on latency for service-to-service communication, especially between on-premise data centers and cloud providers. Are we trading security for a 50ms RTT penalty?
* How API gateways and service meshes integrate (or conflict) with an SSE layer. Is the SSE proxy just another hop, or does it replace certain ingress components?
I learn best from case studies detailing migration pain points, or open-source projects that demonstrate the proxy/connector model. Vendor-neutral technical deep dives would be ideal.
