Azure App Gateway drops TLS 1.0/1.1 today
Impact: legacy clients fail handshakes at the edge from 31 Aug 2025.
Action: set SSL policy to 1.2+, verify backend ciphers, retest ingress before the exec demo.
🔗 Microsoft Learn

Firestore + MongoDB compatibility is GA
Impact: credible driver-swap path for Mongo estates on Google Cloud and Firebase, with Enterprise edition and a free tier.
Action: run a 10-minute driver-swap demo, list unsupported ops, add rollback; confirm regional vs multi-region options.
🔗 Google Cloud

AWS WAF managed rules changed on 29 Aug
Impact: CRS updates can shift allow or block rates mid-trial.
Action: run new rules in Count first, diff the last 7 days of false-positives, re-baseline dashboards.

Script: “Technical acceptance confirmation”
Subject: Technical acceptance confirmation
Body:
We validated [use cases] against [criteria]. Passed [X of Y].

Constraints noted: [limits], [mitigations planned].

Next step: [procurement or security step] by [date].

Please reply “Approved as technically suitable” if accurate.

Usage: send the email the same day the PoC exit criteria are met; attach logs, screenshots, and the runbook snippet.

Firestore multi-region availability: 99.999% SLO
Provenance: Firestore SLA shows credit tiers tied to a 99.999% multi-region SLO.
SE implication: treat multi-region as the default for availability-sensitive PoCs; state the SLO and the region choice in exit criteria.
🔗 Google Cloud

GitHub Copilot coding agent (Enterprise Cloud)
What it does: lets devs delegate repo-scoped tasks to an AI agent from the new Agents panel; Enterprise Cloud supports data residency.
Where it fits: objection handling. Clean answer to “where does our AI data live?” Pair with admin controls in Visual Studio August update.

🔗 IT Pro

Enterprise SE, SaaS infra vendor. Context: late-stage PoC with WAF in front.
Move: before the exec demo, flip AWS Managed Rules updates to Count for 24 hours, tag false-positives, then enable.
Why it works: zero surprise blocks during the demo, clear artefacts for security, and a neat line in the runbook: “Managed rules promoted from Count on [date], FP = [n].”
