    • Summary

    Our boss has asked us to investigate connecting the machines owned by Collegiate Vending, Inc.to the cloud to capture soda product sales. The ultimate goal is to save the messages in an Azure SQL database for analysis and reporting. Our fictitious company has a contract to distribute Coca-Cola products and vending machines to various educational institutions in the United States of America. In aprior article, we created a PowerShell script to write messages to an Azure Event Hub using PowerShell and HTTPS. The diagram below depicts the data flow in our system. Today, our job is to create and configure an Azure Event Hub service for the test program that sends simulated soda machine telemetry to the hub. We need to have an understanding of event hub features before we can successfully deploy a hub.

    The event hub namespace is the logical parent object that can contain one or more event hubs. For those database administrators, a namespace is conceptually the same as a logical database server. It is a unique scoping container that can be reference by a fully qualified domain name (FQDN). Security can be given out at this level; However, I would not recommend it since the end application will have access to all hubs. The namespace deployment is part of the event hub creation when using the Azure Portal. There are two types of Event Hub offerings: single hub and clustered. The fictitious Collegiate Vendingcompany is only processing 200K records per hour. Therefore, the non-cluster deployment has plenty of horse power to handle this processing. The usual information is required to deploy the namespace object. Please see the next section for details. The following information is specific to this service: tier, throughput, and zone redundancy. The Azure Event Hub service has two tiers...

    Now that we are informed about the choices for the namespace, lets deploy the service for our company. A search of the Azure Marketplace brings up two offerings for event hub. Choose the non-clustered installation option. The typical overview page for a service is shown below. Links to documentation and pricing are informative for the first use. Choose the create button to continue the deployment. The image below shows the deployment of a namespace called ehns4tips2020. It is interesting to note that the FQDN contains the servicebus.windows.netaddress. Thus, Azure Service Bus is the foundation of this service. The subscription – pay-as-you-go, resource group –rg4tips2020 and location – east us 2are entered to complete the basic information required by all Azure objects. Click the create button to move onto the next screen. We will need more background information about Event Hubs to finish the deployment selections. Publishers write events to the hub and subscribers read events from...

    The create event hub dialog box allows the user to pick the partition count and message retention period. I choose the maximum choices in the window shown below. You can set the partition count and message retention to 1 for this poof of concept. If you are using the deployment template from the Portal, choose okay to build both the namespace and hub at the same time. The message retention and capture options can be changed after deployment. The partition count is static for the lifetime of the object. Since the Collegiate Vendingcompany is thinking of branching out into snack machines, we want to deploy an additional event hub called ehub4tips2020-snacks. Just choose the "+ Event Hub" button on the overview page of the namespace to start the process. The above image shows two hubs that are associated with our namespace. In the next section, an overview of the screens (blades) dedicated to managing the namespace.

    The Azure portal is where management of the namespace can be done via a graphical user interface (GUI). I am going to break the menu into three parts (images) that can be easily commented on. Not all options are required in most use cases. The overview menu option is the most popular destination. It brings up the current use of the namespace capacity. During the holiday break, I was doing a lot of testing of a Python program connecting to the event hub using AMQP. The results of those tests are seen in the chart below. The access control (IAM) menu option allows for the assignment of Azure rights to users and groups. The typical rights of owner, contributor and readercan be assigned to the appropriate user or group. The Tags menu option is useful when companies want to assign charge backs to departments for use of the Azure Subscription. Many companies enter department, application, component and cost center as descriptive tags to the deployed Azure objects. The shared access polici...

    The publisher/subscriber mechanism of Event Hubs is enabled through consumer groups. A consumer group is a view (state, position, or offset) of an entire event hub. Consumer groups enable multiple consuming applications to each have a separate view of the event stream, and to read the stream independently at their own pace and with their own offsets. We will talk about offsets in a future article. The image below shows two consumer groups have access to the four partitions. In event processing, each application is considered a consumer. There is always a default consumer for each event hub. Going back to our proof of concept, we might want to have one consumer group for each our Azure Function applications. If we want to persist all messages to storage, we could create another consumer group for that effort.

    The Azure portal is where management of the events hubs can be done via a graphical user interface (GUI). The overview menu option displays metrics about requests, messages and throughputat the bottom of the page. These numbers should match the namespace metrics if one event hub is deployed. The summation of the event hub metrics should always equal the container (namespace) metrics. At the top of the page, the four most common menu actions are show as large push buttons. The connect menu brings the user to a screen that can be used to define access policy. Each policy can be granted manage, send, and listen rights. The image below shows a policy for our soda-app. This has been given read and write privileges. Double clicking the policy after definition brings up the SASPolicy. There are two different keys that can be used to connect to the event hub service. While some services have different end points, this service lists the same end point twice. The checkpoint menu brings the us...

    Today, we explored how to deploy and configure both a namespace and event hub for streaming data. It is important to choose certain parameters such as throughput units and partitions correctly at the start of a project. Changes to these properties will require the re-creation of the objects. The details about how to read from the event hub partition were briefly covered. The partition is maintained for N days of retention. That means that various offsets can be used when reading the hub. In the future, I will show how to use Python to read and write to the hub. I am choosing this language since many of the edge device run Linux. Adding Python to this operating system is very simple. The partitioned consumer model allows for the application to read or write to a particular partition. Thus, scale can be achieved through parallelism. If you have multiple applications using the same event hub, it is wise to create a separate consumer for each read. If we were using Event Hub for many Io...
