Microsoft Azure Event Hub is a cloud-based service used to process millions of events as a large data platform and event ingestion service.

Introduction to Azure Event Hub :

Microsoft Azure Event Hub is cloud-based assistance that is utilized as a major information stage and occasion ingestion administration by handling a huge number of occasions in short order. Information created or put away in the source framework can be shipped off the occasion center and the client can play out the important change on information lastly, it tends to be put away utilizing continuous ingestion method or by group/stockpiling processes. The purplish-blue Asian center point is utilized for abnormality discovery, application logging, or applications where continuous information is required like live dashboarding, and so on.

How does Azure Event Hub work :

Azure event hub processes data easily in real-time so that users can get more insight into data. It uses a distributed processing platform used in Hadoop to process data with low latency and has integration with data analytics services. Event hubs are like a “front door” to the event pipeline and act as an event ingester. Event ingester lies in between the event punisher and consumer. It is a unified streaming service to decouple the producer from the event consumer.

For processing, the stream of data Event hub uses the below component:

  1. Event producers: It is an endpoint that engages customers with event hubs using the HTTP or Apache Kafka protocols. Any type of data sent to the hub is first published using the event publisher/producer.
  2. Partitions: The event hub streams a message which is partitioned so that based on partition consumers can only read the particular subset of the partition of the streamed message.
  3. Consumer groups: The event hub follows the mechanism of publishing and subscribing and this is enabled in the event hub using the consumer group. It provides the state, position, and offset view of the event hub. Based on the subscription of the consumer group they can view the event stream in the event hub. Consumer groups can read or view the stream based on their pace and offset.
  4. Throughput units: To control the throughput capacity users can pre-purchase the units of capacity in the Azure Event Hub.
  5. Event Receiver: it is an entity used to read the data from the event hub. AMQP 1.0 sessions are used to connect the All event hub consumers. This session is used to deliver Event hub services as soon as they are available. For real-time streaming and ingestion of data, Apache Kafka uses Kafka consumers which are connected using Kafka protocol 1.0 or later.

How to Create and Use Event Hub in Azure :

Before learning to create the Azure Event hub users must have an Azure subscription so that they can log in with valid credentials to the Azure Portal.

Step #1

Use a valid certificate to login into the Azure portal:


Step #2

Search Create a resource link to all services on the Azure portal Search and select Create a resource from Azure services.


Step #3

Now select the +Add to add a new resource group in Azure:


Step #4

Enter resource group details as needed:


Step #5

Then select the Create Review + button and then create to create a new resource group, a new resource will be created as below.


Step #6

Now go to the Azure portal home page and then go to all the services


Step #7

Search for event hubs on Azure services:


Step #8

Select Event Hub from the page and click + Add to create a new event hub:


Step #9

Create a namespace page now Select Resource Group, Subscription, Location, Pricing Level (Basic or Standard) as well as Throughput Unit:


Step #10

Now select Review + Create and then create a new event hub to CDPlay:


Step #11

If deployment is successful, select Go to Resource.


Step #12

Check for Event Hub in the left panel under Entity and select Event Hub:


Step #13

To add a new event, select Event Hub from the Event Hub page:


Step #14

Provide details and partitions for the new event, and then click Create to add a new event:


Uses of Azure Event Hub :

  1. It supports real-time data processing so can be used in anomaly detection, live dashboarding, and any type of real-time analysis as part of Big Data Analytics.
  2. Data supports both real-time as well as batch processing.
  3. Azure Event Hub uses cloud-based services so it is scalable and users can start streaming in megabytes and it can be expanded to GB or TB.
  4. It is a fully managed platform-based service so monitoring and management overhead is less required.
  5. It has a rich ecosystem because it supports the Apache Kafka ecosystem so that the Kafka protocol is used to transfer data between producers and consumers.
  6. Azure Event Hub supports multiple languages ​​like .NET, Python, Java, Scala.

Conclusion :

Microsoft Azure Event Hub is the assistance of Azure cloud to assist Ingesting information progressively or cluster so clients with canning get additional significant knowledge from the information and send the application on mists or some other framework effortlessly. It has support for a very long time and stages and uses the apache Kafka environment for information ingestion. Clients who need to ingest a lot of information significantly quicker to further work can incline toward the Azure Event Hub administration as it is not difficult to utilize and require less manual impedance.
