Reviving the Messaging Network for Hybrid Multi-Cloud Solutions

1. Core Assumptions to Challenge

  • Messaging Networks = Essential Backbone:

    • Assumes that rebuilding a messaging network is superior to optimizing or extending existing API-driven models (e.g., gRPC, GraphQL federation).

    • Implicitly bets on messaging middleware revival rather than application-layer innovation.

  • Hybrid Multi-Cloud is the Norm:

    • Assumes most enterprises are operating true hybrid or multi-cloud setups needing complex cross-domain messaging.

    • In practice, many companies still centralize workloads into one dominant provider (e.g., AWS-centric with satellite services).

  • IBM MQ as Ideal Solution:

    • Presupposes that MQ-style solutions can evolve fast enough to meet cloud-native expectations (autoscaling, event-driven, ephemeral workloads).

    • Risks ignoring newer event systems (e.g., NATS, Pulsar) that offer "modern messaging" with different assumptions.

2. Potential Blind Spots

  • Cloud-Native Messaging Models:

    • Kafka, Pulsar, EventBridge, Pub/Sub — cloud-native services are often good enough for most needs, without needing explicit "networks of queues."

  • Operational Complexity:

    • Building a global messaging network increases the operational surface: security policies, inter-domain routing, peering agreements, observability — complexity that cloud-native messaging services abstract away.

  • Cost Model Shifts:

    • Saving on egress is good — but running global messaging meshes can introduce infrastructure costs (VMs, networking, ops staff) that aren't trivial.

  • Dev Culture Shifts:

    • Today's developers are more API-oriented (REST, GraphQL, Webhooks) — forcing a "messaging first" mindset could increase friction unless developer experience is radically simplified.

3. Risks

  • Overengineering:

    • For many apps, HTTP/2 or lightweight event systems are good enough. Complex messaging infrastructures might be oversized for the actual problem.

  • Lock-in Risk:

    • Building deeply into IBM MQ or proprietary messaging networks could limit cloud portability if future strategies change.

  • Security Holes:

    • Messaging networks require trust brokering between domains — a ripe target for misconfigurations or insider threats.

  • Innovation Lag:

    • If messaging network tech evolves slower than cloud-native application patterns (e.g., serverless, edge computing), enterprises might be stuck maintaining legacy scaffolding.

4. Alternative Viewpoints

  • API-First with Messaging Backplane:

    • Instead of a primary messaging network, treat messaging as a backplane behind APIs, only invoked for async recovery or retries.

  • Event-Driven Cloud Services:

    • Architect around cloud-native event services, accepting some vendor lock-in for agility gains (e.g., EventBridge, EventArc, Azure Event Grid).

  • Selective Hybrid:

    • Recognize that full hybrid/multi-cloud messaging is only needed for a small subset of business-critical flows (not for every app).

🧠 TL;DR

While the "Reviving the Messaging Network" idea is strong for certain critical, multi-domain, low-latency workflows, it overassumes universality, underestimates cloud-native evolution, and risks operational overhead without careful scoping.
Use selectively, not dogmatically.
