Certified Azure Event Grid Licensing Provider
Clear, practical support to license and optimise your event-driven solutions
As a certified Microsoft Azure Partner, Claria helps organisations design licensing strategies for Azure Event Grid that align with their real-world event-driven architectures and future scaling needs.
Azure Event Grid doesn’t use traditional license purchases or renewals, it operates on a flexible pay-per-operation model, where you are billed monthly based on actual usage. This model adds some flexibility, but requires careful planning to avoid unnecessary costs.
How Azure Event Grid licensing works
Azure Event Grid displays different prices based on the number of operations you perform. An operation includes:
Event Publication
Events sent into Event Grid.
Advanced Matching
Filtering and evaluating events based on rules.
Delivery Attempts
Successful and retried deliveries to subscribers (push or pull).
Dead-Lettering
Managing events that fail to deliver after retries.
Each event operation is measured in 64 KB units, larger events incur additional charges.
Azure Event Grid also offers a monthly free allotment of operations, after which charges apply per additional operation processed.
Why careful Azure Event Grid licensing planning matters
Without proactive event traffic modelling, it's easy to underestimate:
Event volumes generated by telemetry, IoT, microservices and user actions.
Costs associated with retries, filtering and dead-letter management.
Additional operations incurred by hybrid and cross-cloud event flows.
How Claria helps with Azure Event Grid Licensing
Our licensing and optimisation support includes:
Event traffic forecasting
Analysing your systems to model realistic event generation patterns.
Cost-effective event architecture
Designing routing, batching and filtering strategies to minimise operations.
Scaling strategy development
Planning licensing for future event growth based on business and technology roadmaps.
Governance and monitoring setup
Implementing operational monitoring to manage, alert and optimise usage over time.
Azure Event Grid Pricing and Cost
Azure Event Grid is designed to make real-time, event-driven architectures accessible and scalable without upfront licensing costs. You pay only for what you use, every event published, filtered, delivered, or dead-lettered is an operation.
This flexible, pay-per-operation model makes Azure Event Grid highly attractive, but true cost efficiency depends entirely on how your event-driven architecture is designed.
However, the real price of running Azure Event Grid depends entirely on how your architecture is designed, how many events you generate and how efficiently you route and manage them.
How Claria helps on Azure Event Grid pricing
At Claria, we work closely with you to:
Analyse your business processes and event flows
Model realistic operational patterns
Calculate projected monthly costs based on your real-world architecture and scaling plans
Identify optimisation strategies to minimise unnecessary operations and costs
We help you build a clear, realistic picture of what your Azure Event Grid project will truly cost today and as it grows.
When to use Azure Event Grid
Azure Event Grid is ideal when your systems need to react in real-time to events and changes, both within Azure and across hybrid or multi-cloud environments. It enables organisations to move from traditional, request-driven architectures to scalable, event-driven models that improve agility, resilience and operational efficiency.
Here’s when Azure Event Grid is the right solution:
You need real-time event-driven integration
When applications, services or business processes must respond instantly to changes (such as file uploads, system updates, or user actions), Event Grid provides low-latency, scalable event delivery.
You want to simplify event management
Instead of building custom polling mechanisms, complex APIs, or heavy middleware, Event Grid offers a centralised, fully managed event routing system that reduces operational complexity.
You require large-scale event distribution
If you need to distribute millions of events per second across multiple applications, services and regions, without losing performance or control, Event Grid is designed for that scale.
You are building serverless architectures
Azure Event Grid works natively with Azure Functions, Azure Logic Apps and other serverless components, making it easy to trigger workflows and automate operations without maintaining infrastructure.
You need hybrid or cross-cloud eventing
When events must flow securely across cloud and on-premises systems, or even between different clouds, Event Grid provides the necessary routing, security and governance frameworks.
You need secure, governed event flows
With support for RBAC, managed identities and encryption, Event Grid helps you maintain strong security postures while handling critical event-driven communication.
Azure Event Grid Considerations
At Claria, we work with you from the earliest stages to answer the critical strategic questions that shape your event-driven architecture. Our goal: to ensure your Azure Event Grid implementation is resilient, compliant, scalable and fully aligned with your operational models and business goals. Here’s what we explore together before starting any Azure Event Grid project:
Event-driven systems rely on consistent event schemas and metadata. You need to define clear standards for event formats, subjects and types to avoid integration complexity and inconsistent consumer behaviour.
Depending on your architecture, real-time HTTP push delivery may be ideal, or you may need pull delivery for systems that must control event consumption rates. Choosing the right model affects event flow reliability, scaling and latency.
Event Grid guarantees at-least-once delivery, which means consumers must be designed to handle potential duplicate events safely and idempotently to ensure data consistency.
You must plan for access control, encryption, authentication (e.g., managed identities) and auditing across all event publishers, subscribers and intermediaries, especially in hybrid or cross-cloud environments.
Handling undelivered events effectively is critical. Define dead-letter queues and retry policies tailored to the importance and criticality of your event types to avoid data loss and operational risks.
Event-driven systems require proactive observability. Plan for monitoring metrics like delivery failures, subscription health, event processing latencies and implement alerting on operational anomalies.
Consider how Event Grid interacts with existing messaging systems (Service Bus, Event Hubs), serverless platforms (Functions, Logic Apps) and APIs to avoid architectural fragmentation.

Azure Event Grid FAQs
Azure offers multiple messaging services (Event Hubs, Event Grid and Service Bus) each tailored to specific messaging and event-driven scenarios:
Azure Event Hubs is a big data streaming platform and event ingestion service, capable of receiving and processing millions of events per second. It is designed for high-throughput telemetry ingestion, such as collecting data from IoT devices, applications, or infrastructure for further processing and storage.
Analogy: Like a pipeline, constantly streaming high-volume data into storage or analytics systems.
Azure Event Grid is a fully managed event routing service that delivers discrete events from publishers to subscribers. It is optimised for reacting to events in near real-time, triggering processes in services like Azure Functions, Logic Apps, or custom applications.
Analogy: Like a Like a news broadcaster, it announces that something happened and interested parties can choose to react.r analytics systems.
Azure Service Bus is a reliable message broker with queues and topics, designed for ordered, durable and transactional messaging between distributed systems.
Analogy: Like a postal service, it guarantees that the message is delivered, even if it requires retries or waiting in a queue.
Azure Event Grid uses a push-based delivery model.
Events are pushed to configured endpoints such as webhooks, Azure Functions, Logic Apps, or custom HTTP endpoints.
Event Grid includes built-in retry mechanisms with exponential backoff to handle temporary endpoint unavailability.
If delivery continues to fail, the event may be placed in a dead-letter destination if configured.
There is no pull model in Event Grid; consumers cannot fetch events manually from the service
To integrate Azure Event Grid with your applications:
Create an event subscription for an event source (such as a storage account, Event Hub, or custom topic).
Specify an event handler, such as an Azure Function, Logic App, or custom HTTP endpoint, to process the incoming events.
Configure filters and delivery settings if necessary to control which events are delivered and how they are handled.
Integration can be performed using the Azure Portal, Azure CLI, Azure SDKs, or ARM templates.
Azure Event Grid provides several security features:
Authentication and authorisation: Event Grid supports Azure Active Directory (AAD) authentication and Shared Access Signature (SAS) tokens to validate senders and receivers.
Encryption: All data is encrypted at rest using Microsoft-managed keys and in transit using HTTPS.
Access control: Azure Role-Based Access Control (RBAC) manages permissions for sending events, creating subscriptions and managing resources.
IP filtering and private endpoints: Event Grid supports network security features to restrict access to approved clients only.
These measures ensure that events are securely transmitted and accessed only by authorised entities.
To get started with Azure Event Grid:
- 1.
Choose or create an event source, such as a Storage Account or Event Hub.
- 2.
Create an Event Subscription, specifying the event source and the destination where events should be sent (e.g., an Azure Function or a webhook).
- 3.
Configure any necessary filters to ensure only relevant events are delivered.
- 4.
Develop and deploy the event handler that processes the incoming events.
- 5.
Use the Azure Portal, Azure CLI, or Azure SDKs to manage and monitor event subscriptions and delivery status.
Azure Event Grid ensures reliable event delivery through several mechanisms:
At-least-once delivery guarantee: Events are delivered at least once to each configured subscriber.
Built-in retry policies: If a delivery attempt fails, Event Grid retries delivery with an exponential backoff strategy.
Dead-lettering: If all retries fail, events can be sent to a dead-letter destination for later analysis, provided the dead-letter feature is configured.
High availability: Event Grid operates on a globally distributed infrastructure to provide high resilience and redundancy.
These features help maintain delivery reliability even during transient failures.
Failover handling in Azure Event Grid depends on the selected data residency configuration:
If the "cross-geo" option is selected, subscription metadata is replicated automatically to a paired Azure region. In the event of a major regional outage, Microsoft may initiate a failover to the secondary region without user intervention.
If the "regional" option is selected, data is not replicated across regions and the customer must implement their own disaster recovery plan if regional availability is lost.
It is important to note that while subscription configuration is replicated in cross-geo scenarios, event data itself may not always be automatically transferred between regions.
