The Problem
Eight Azure Service Bus problems that teams bring to AceMQ, from sessions that cap throughput and messages that dead-letter on lock expiry, to a namespace that throttles at month-end and Geo-DR that has never been failed over. If one describes your week, that is where the review starts.
Sessions serialise processing onto one consumer and throughput will not go past it
Messages dead-letter on lock expiry, so the handler never gets a fair second attempt
The namespace hits its messaging-unit ceiling at month-end and starts throttling
Duplicate detection is enabled but the detection window is shorter than the retry interval
Subscription filters have accumulated to the point that nobody can say who receives what
Geo-disaster recovery is paired and has never been failed over in a test
Standard-tier throttling surfaces as intermittent client errors that look like application bugs
Premium namespaces were provisioned per team and the combined cost is now hard to defend
A good fit if you run Azure Service Bus in production, on Standard or Premium, and want senior engineers who know its failure modes and stay on a problem until the root cause is written down.
Not a fit for small teams with non-critical workloads. AceMQ is not a budget consultancy: we work with enterprises running business-critical and compliance-heavy Azure Service Bus.
How it breaks, and the fix
A message that fails every time is abandoned and delivered again, up to the queue's maximum delivery count. With that count set high and no backoff, one poison message becomes a retry storm: consumers spend their time on it, the namespace is loaded, and the queue behind it backs up.
One poison message, one retry storm
Two producers, one Premium namespace, three queues
NamespaceAll three queues drain as fast as the producers send. Namespace load is low and every dead-letter queue is empty.
The adjudication worker throws on one malformed claim and abandons it. It comes straight back, again and again. The queue backs up, the namespace is loaded, and both producers are throttled, even on the intake and notification queues.
The worker dead-letters a message that can never succeed, with a reason, and retries transient errors with a backoff. The delivery count is low, an alert watches the dead-letter queue, and the other queues never noticed.
A poison message with no limit on retries, and a dead-letter queue nobody reads, are two of the reasons teams call AceMQ about Azure Service Bus. The fix is split between code and configuration: a low maximum delivery count, an explicit dead-letter call with a reason and description for failures that will never succeed, exponential backoff for transient ones, lock duration and renewal sized for the slowest handler, and alerts on dead-letter count and entity size. Service Bus never cleans a dead-letter queue, and its messages count toward the same quota as the live queue, so an unwatched one can end in failed sends. The Premium tier reserves capacity and Standard throttles on shared credits, so AceMQ checks which applies.
Our Services
AceMQ runs four Azure Service Bus service lines: namespace architecture and consulting, enterprise integration with Azure, migration onto Service Bus, and performance and cost optimization. A senior engineer leads each one, and any of them can roll into 24/7 support with a 15-minute emergency SLA.
We design Azure Service Bus namespaces, queues, and topics sized for your throughput and availability requirements. Every design includes geo-redundancy, retry policies, and a dead-letter strategy from day one.
We integrate Azure Service Bus with Logic Apps, Event Grid, Azure Functions, and API Management. Managed identity authentication eliminates credential management across every integration point.
We migrate IBM MQ, RabbitMQ, and ActiveMQ deployments to Azure Service Bus while preserving message semantics and minimizing application changes. Every migration includes a tested rollback plan.
Azure Service Bus costs scale with operations and Premium unit hours. We model your workload to maximize throughput while keeping spend predictable.
Named senior engineers on your account — 15-minute emergency response, no ticket routing, no junior triage.
24/7 Support
AceMQ Azure Service Bus support gives you a named senior engineer and a 15-minute first response when production is down, 24/7, on Standard and Premium namespaces. Lower severities get 1-hour, 4-hour and next-day responses, and every P1 ends with a written root-cause analysis.
P1 escalation path
A replay of one P1, from the first page to the written root-cause analysis
15-minute P1 response, 24/7.
A response time, not a resolution time.
P1 opened, on-call engineer paged
Phone, email or Slack reaches the on-call senior engineer directly, whether the incident is in RabbitMQ, Kafka, Redis, PostgreSQL or Kubernetes. No web form, no tier-1 queue.
Senior engineer on your bridge
A senior engineer who already knows your environment joins a live bridge, so nobody has to re-explain your topology.
Specialists across the stack join
When an incident crosses components, the engineers who know each one join. For RabbitMQ, the path runs to the core team.
Written root-cause analysis
Root cause, the fix applied and the prevention steps, delivered after every P1.
Beyond SLAs — the model behind senior-only, zero-cold-start expert access.
Every ticket is handled by a senior SME assigned to your account — not a pool of anonymous agents. Zero cold-start. No re-explaining your environment.
Any ticket can be escalated to a live session with your named engineer via calendar booking. No gatekeeping, no approval required — direct access, always.
Quarterly health checks on your deployment plus shared intelligence from our support customers — we surface risks before they reach production.
How It Works
An AceMQ Azure Service Bus engagement runs in four stages: a namespace and entity assessment of 1 to 2 weeks, written findings within a week, changes made with your engineers and staged per entity, then a handover with runbooks for dead-letter handling, throttling and Geo-DR failover.
1–2 weeks
We review namespace tiering, queue and topic layout, subscription filters, lock durations, prefetch and messaging-unit headroom against the throughput and ordering your applications actually need.
Within a week
Prioritised findings with the reasoning attached, including where tier changes or namespace consolidation would pay for themselves.
Scoped per engagement
We change entity configuration, client settings and retry behaviour with your engineers rather than around them, staged per namespace and reversible at each step.
Ongoing
Runbooks for dead-letter handling, throttling and a tested geo-DR failover, plus 24/7 support with a 15-minute emergency SLA if you want it.
A senior engineer, not an SDR. No sales sequence attached.

Support and managed services
Four tiers of ongoing cover once you are live. Each tier hands more of the day-to-day work to AceMQ, from a 15-minute emergency SLA to AceMQ hosting and running Azure Service Bus for you.
Compare the four Azure Service Bus support tiersSide by side
Azure Service Bus Standard runs on shared capacity and throttles on credits when traffic bursts. Premium reserves dedicated capacity in messaging units and adds private endpoints, geo-replication, JMS 2.0 and larger messages. Either way, dead-letter handling, lock duration and retry design stay with your application, and that is the layer AceMQ covers.
| Question | Standard tier | Premium tier |
|---|---|---|
| How is capacity provided? | Shared capacity. A burst can return throttling errors such as ServerBusy. | Dedicated resources sized in messaging units, so throughput is predictable once the units are sized correctly. |
| How is it billed? | A base charge plus operations, so cost follows message volume and how your clients poll and settle. | A rate per messaging unit, so cost follows the capacity you reserve. |
| What is the largest message? | 256 KB. | Much larger: up to 100 MB over AMQP. |
| Can the namespace be isolated on a private network? | No private endpoints or network service endpoints. Those are Premium features. | Yes, with private endpoints and network service endpoints. |
| Does it support JMS and geo-redundancy? | Only a JMS 1.1 subset focused on queues, and no geo-replication or Geo-DR pairing. | JMS 1.1 and 2.0, Geo-DR pairing for entity definitions, and geo-replication that also copies message data. |
| What stays with your team on either tier? | Dead-letter handling, lock duration, retries and idempotent handlers. | The same, plus sizing and scaling the messaging units. |

One partner, not five
Azure Service Bus rarely fails in isolation. AceMQ covers the full surrounding infrastructure — so one team owns the whole path instead of pointing at each other.

Choose Premium when you need predictable throughput, private endpoints, geo-redundancy, JMS 2.0, customer-managed keys or messages above 256 KB. Standard shares capacity and throttles on credits when traffic bursts. AceMQ measures sustained and peak operations first, because moving tier without sizing the messaging units only relocates the ceiling.
A named AceMQ senior engineer answers within 15 minutes, 24/7, when Azure Service Bus is failing production traffic. Lower severities get a first response within 1 hour, 4 hours or the next day. AceMQ works on your namespace configuration, client behaviour and design. A fault in the Azure platform itself still goes through Microsoft support.
An AceMQ Azure Service Bus engagement starts with a free consultation with a senior engineer, booked in our reply within 1 hour. Next comes a namespace and entity assessment of 1 to 2 weeks covering tier, messaging units, queues, topics, sessions, dead-lettering and client settings. Written findings and a plan follow within a week, before anything changes.
Yes. AceMQ assigns a named senior engineer from its team of 11+ who works with your engineers rather than around them, changing entity settings, retry logic and alerts together. Every change is staged per entity and reversible, and you keep the runbooks for dead-letter handling, throttling and Geo-DR failover when the work is done.
Duplicates usually mean a handler runs longer than the lock duration, so the message becomes visible again while the first attempt is still working and a second consumer picks it up. The first handler then fails to complete with a lost-lock error. The fix is lock renewal, a longer lock, idempotent handlers and, where it fits, duplicate detection with a long enough window.
The cause is on each message as its dead-letter reason: MaxDeliveryCountExceeded, TTLExpiredException and HeaderSizeExceeded each need a different fix. Service Bus never cleans a dead-letter queue, and its messages count toward the same quota as the live queue, so an unwatched one can eventually make sends fail with a quota error. AceMQ sets the alerts and a replay path.
Yes. AceMQ maps JMS, AMQP and queue manager semantics to Service Bus queues, topics and sessions, runs the old and new side by side, and cuts over flow by flow with a rollback. AceMQ also says plainly when staying on the current broker is the better answer for the workload.
Yes. AceMQ works on Azure Service Bus in two ways: ad hoc engagements for a defined piece of work, such as a health check, an upgrade or an incident, or an annual partner engagement that covers 24/7 support, proactive reviews and named engineers. Many teams start ad hoc and move to an annual partnership once the first engagement is done.
Every AceMQ proposal is tailored to your requirements: your Azure Service Bus environment, the SLA you need, the hours of cover and the scope of work. Most contracts run $24,000–72,000 a year, depending on the SLA, the scope and how Azure Service Bus is deployed, with aggressive discounts when several technologies share one contract.
