What does AceMQ Google Cloud Pub/Sub support include?

Our Pub/Sub support covers 24/7 emergency incident response with a 15-minute SLA, root cause analysis on every P1, throughput and latency tuning, cost and quota review, integration support for hybrid estates, and design review before major topology changes. Every ticket is handled by a named senior engineer assigned to your account. There is no tier-1 triage layer and no per-incident charge.

Pub/Sub is fully managed by Google. What is there to support?

Google operates the service; you still own everything that determines whether it works for you. Ack deadlines, ordering key design, flow control limits, push endpoint behavior, subscription filters, dead-letter policy, and retention settings are all yours, and in our experience they cause the overwhelming majority of production incidents. Google support will confirm the service is healthy — which is usually true and rarely the answer you need at 3am.

Why did our throughput drop after we enabled message ordering?

Pub/Sub guarantees ordering per ordering key, and delivers messages for a single key strictly one at a time. If your ordering key has low cardinality — a constant, a region, a single large tenant — every message for that key queues behind the previous one, and a subscription that was parallel becomes serial. The fix is almost always key redesign toward higher cardinality rather than adding subscriber capacity, which does nothing.

How fast do you respond to a Pub/Sub production incident?

P1 emergencies — backlog growing uncontrolled, subscribers stalled, publish path failing — get a 15-minute first response with a senior engineer joining a live bridge. P2 critical issues are 1 hour, P3 high-priority 4 hours, and P4 standard questions next business day. These are contractual, not best-effort targets.

Do you support Pub/Sub alongside Kafka or on-premise brokers?

Yes, and that is a large share of what we do. Most enterprises running Pub/Sub also run Kafka, RabbitMQ, or IBM MQ somewhere, with bridges between them. We support the brokers on both sides and the connectors between, including where ordering and delivery guarantees change as a message crosses the boundary — which is where cross-platform incidents almost always originate.

Can you help us migrate to or from Pub/Sub?

Yes. We plan and execute migrations between Pub/Sub, Kafka, RabbitMQ, and traditional MQ with zero message loss, including semantic mapping, parallel-run validation, and canary cutover. We will also tell you honestly when a migration is not warranted — several teams have come to us convinced they needed to leave Pub/Sub when the actual problem was a subscription setting.

How is AceMQ Google Cloud Pub/Sub support priced?

Support is priced as an annual contract based on your environment size, required SLA tier, and coverage hours — not per incident or per ticket. Calling us during an outage never carries a cost decision. Contact us for a quote; we turn them around within 24 hours.

Google Cloud Pub/Sub Support

24/7 Google Cloud Pub/Sub Support with a 15-Minute Emergency SLA

Pub/Sub is managed, but the failure modes are still yours: ack deadlines expiring under slow handlers, ordering keys serializing your throughput to one stream, push subscriptions backing up behind a 503, and exactly-once semantics quietly degrading. Every ticket reaches a named senior engineer who already knows your subscription topology.

Incident Triage

Google Cloud Pub/Sub problems we fix every week

These are real symptoms from real Google Cloud Pub/Sub production environments — and the first thing our engineers check when one comes in.

Symptom you're seeingWhat we check firstTypical resolution

Same messages delivered over and over, backlog never drains

What we check firstAck deadline against actual handler p99. If processing outlives the deadline, Pub/Sub redelivers while the first attempt is still running — so throughput drops as duplicate work multiplies. We check whether the client library's lease extension is running and whether a blocked thread pool is starving it.

Typical resolutionUnder 1 hour

Throughput collapsed after enabling message ordering

What we check firstOrdering key cardinality. Pub/Sub delivers one ordering key strictly serially, so a low-cardinality key — a single tenant ID, a constant, a date — turns a parallel subscription into one stream. We look at key distribution before touching anything else.

Typical resolution1-3 hours

Push subscription backlog climbing, no consumer errors visible

What we check firstThe push endpoint's HTTP response codes and latency. Anything that isn't 2xx counts as a nack, and Pub/Sub then backs off — so a dead or 500-ing endpoint produces a growing backlog with silence on the subscriber side. We pull the delivery metrics and hit the endpoint directly.

Typical resolutionUnder 1 hour

Exactly-once subscription still producing duplicates

What we check firstWhether acks are actually succeeding. With exactly-once enabled, an ack that fails or arrives after the deadline is not honored, and the message is legitimately redelivered. We check ack response futures, the extended deadline window, and whether the client library version supports the guarantee at all.

Typical resolution2-4 hours

Oldest unacked message age growing while subscribers look idle

What we check firstFlow control settings against message size. A subscriber that has hit maxOutstandingBytes stops pulling entirely and looks healthy in every dashboard — CPU flat, no errors — while the backlog climbs behind it.

Typical resolution1-3 hours

Messages silently disappearing before consumers see them

What we check firstSubscription message retention, dead-letter topic configuration, and filter expressions. A subscription filter that no longer matches an evolved payload schema drops messages at the subscription, not the topic — and produces no error anywhere.

Typical resolution2-4 hours

Publisher latency spiking, publish futures timing out

What we check firstBatch settings and per-region publish quota. Aggressive batching plus a quota ceiling produces retry storms that look like network trouble; we separate quota rejections from genuine latency before changing client config.

Typical resolutionUnder 2 hours

Dead-letter topic filling up with messages that look fine

What we check firstMax delivery attempts against transient downstream failures. A dead-letter policy tuned for poison messages will also drain perfectly valid traffic during a downstream outage, which is usually the wrong outcome and needs different retry handling.

Typical resolutionSame day

Resolution times reflect typical Google Cloud Pub/Sub engagements under an active AceMQ support contract. Every P1 closes with a written root-cause analysis.

What's Included

Everything in your Google Cloud Pub/Sub support contract

No add-on pricing for incidents. No per-ticket charges. One contract covers the whole surface.

Emergency Incident Response

Backlog growing, subscribers stalled, or a publish path failing. A senior engineer joins a live bridge within 15 minutes with access to diagnose against your project — not a ticket acknowledgement.

Root Cause Analysis

Every P1 closes with a written RCA: what failed, why, the fix applied, and the specific subscription or client change that prevents recurrence. Delivered as standard, not on request.

Throughput & Latency Tuning

Ack deadlines, flow control limits, ordering-key design, batch settings, and subscriber concurrency tuned against your real message sizes and handler timings rather than library defaults.

Cost & Quota Review

Pub/Sub bills on data volume, retention, and inter-region traffic. We find the subscriptions retaining seven days for no reason, the cross-region pulls nobody intended, and the retry loops paying twice for the same message.

Hybrid & Multi-Cloud Integration

Pub/Sub rarely lives alone. We support the bridges into Kafka, RabbitMQ, and on-prem MQ estates — Dataflow paths, Pub/Sub connectors, and custom relays — including ordering and delivery guarantees across the boundary.

Migration & Design Review

Kafka or RabbitMQ to Pub/Sub, Pub/Sub Lite consolidation, and topic and subscription design reviews before you scale a schema decision you cannot easily reverse.

Anywhere You Run It

We support Google Cloud Pub/Sub wherever it's deployed

Why AceMQ

What you get that you don't get elsewhere

Named Engineers, Zero Cold Start

The same senior engineers stay on your account. They know your topic layout, your ordering strategy, and your subscriber runtime — so a P1 call starts with diagnosis, not twenty minutes of you explaining your project structure.

No Tier-1 Triage Layer

You reach a senior messaging engineer directly by phone, email, or Slack. No help desk collecting information to pass along, no case number that sits overnight, and no escalation approval standing between you and someone who can fix it.

We Know What Pub/Sub Replaced

Most Pub/Sub incidents come from patterns carried over from Kafka, RabbitMQ, or IBM MQ that Pub/Sub models differently. We support all of them, so we recognize a consumer-group assumption or a queue-depth mental model on sight.

Genuine Follow-the-Sun Coverage

Engineers across 26+ countries and every time zone. Your 3am incident is someone's mid-afternoon — no overnight skeleton crew, no waiting for a region to wake up.

Beyond What Google Support Covers

Google will tell you the service is healthy, and it usually is. The problem is normally your ack deadline, your ordering keys, or your subscriber's flow control — the application-side surface a platform vendor cannot debug for you.

Full-Stack, Not Just the Broker

Pub/Sub problems are often not Pub/Sub problems. We diagnose across the client library, the JVM or runtime, GKE resource limits, VPC egress, and IAM — because that's where the root cause frequently actually lives.
