3 Interesting Facts About Using Azure Service Bus

Service Bus message is like a message in a bottle. It is absolutely great.

Running an enterprise business is all about keeping up with the expectations of customers and meeting the supply demands in time. What customers of this century care about most is time! This is why effective queue management is crucial to automate customer flow. Plus, if employees stay occupied to organize the queue, this can lead to a sheer drop in staff’s productivity. An effectively managed queue can promise customer loyalty and improved services.

The true efficiency of an enterprise business can be measured by the rate by which the random walk-in customers are turned into potential customers. But it may happen that many customers don’t complete their purchase and leave the queue. The queue management systems are designed to improve the waiting experience by centralizing the information flow. This means that the customer will be certain about how much he has to wait and the staff would also be aware of the customer’s needs and specifics which streamlines many aspects of the queue.

To develop an effective queue management system, queue mechanisms are applied to the enterprise business. Either a single-channeled system or a multi-channeled system can be used based on the availability of servers. To figure out which customer do you need to serve next considering the behavior of customers, the queue mechanisms are found helpful. Usually, there are five queue mechanisms that are practiced; FIFO (First In First Out), Priority Queuing (PQ), Custom Queuing (CQ), Weighted Fair Queuing (WFQ), Class-Based Weighted Fair Queuing (CBWFQ), and Low-Latency Queuing (LLQ).

FIFO is probably the most primitive and simple form of queuing mechanism. This mechanism is based on the popular enterprise expression: first come first serve. Those who come first in the queue are dealt first and the rest are put to the waiting and don’t get served until the previous ones are finished being in the queue. While Priority Queueing responds to the significant customers first. This mechanism discriminates in view of packet source, packet destination, its type, label, and so on to channelize and regulate the traffic flows. The biggest drawback associated with PQ mechanism is the high volumes of prioritized traffic which leaves the low-prioritized traffic completely neglected.

You can manage your business operations in a more effective, pragmatic, and profound way

Weighted Fair Queuing renders two significant benefits; it supports variable-length packets and it offers impartial queuing which splits the available bandwidth across queues of traffic, based on weights. This is by no doubt an effective queuing mechanism that resolves the issue of low prioritized traffic being neglected as WFQ assigns each queue a weight which makes flows with different bandwidth requirements possible. But if a correct, befitting, and a compatible queuing mechanism is chosen successfully for your enterprise business, then you can manage your business operations in a more effective, pragmatic, and profound way, garnering more sales and consequently become more successful.

How to write messages into an Azure Service Bus Topic:

Create message in Azure Service Bus Topic

To create a message in Azure Service Bus, first load the NuGet package into your .NET Core assembly:
https://github.com/Azure/azure-service-bus-dotnet

After that, you just need to write some lines of code like in the example to create a message into a specific Service Bus Topic.

How to get triggered, when new messages arrived an Azure Service Topic:

Select Azure Development in Visual Studio Installer

Azure Development

If you want to use Visual Studio 2017 make sure you installed the prerequisites for Azure Development before using the Visual Studio Installer. Using Visual Studio Code you will find all these extensions in the Extensions tab of VS Code.

Create a new Azure Function

Use your favorite IDE like Visual Studio 2017, Visual Studio 2019 or Visual Studio Code. In the example you will see how to create an Azure Function (Version 2: .NET Core) in Visual Studio 2017. Click:
File -> New -> Project

Use your Azure Functions template

Navigate to Cloud -> Azure Functions and set a meaningful name for the Service Bus Trigger.

Now, before we continue, we should pick up all required setting from the Service Bus in Azure. Let's do that in the next steps before we continue in Visual Studio.

Navigate to the Service Bus Ressource in Azure

Select the Sevice Bus namespace, select "Shared access policies" in the navigation on the left hand side, use the right policy (default: "RootManageSharedAccessKey"). Copy the Primary Connection String.

Navigate to the Service Bus Ressource in Azure

Select the Sevice Bus namespace, select "Shared access policies" in the navigation on the left hand side, use the right policy (default: "RootManageSharedAccessKey") and copy the Primary Connection String.

Select the right Service Bus Topic

Add new Service Bus Topics if not already done. Select an existing topic of your choice.

Select the name of the Subscription

Navigate to "Subscriptions" and fix the name of the subscription. Keep it in mind for the next step.

Select the name of the Subscription

Navigate to "Subscriptions" and fix the name of the subscription. Keep it in mind for the next step. Now go back to Visual Studio 2017, continue now adding the new project

Continue in Visual Studio

Create the project, press "OK"

Select Azure Functions v2 (.NET Core)

Find Service Bus Topic trigger in the collection. Insert the Connection String from the Clipboard, insert also the Topic name as well as the Subscription name

Ready to start

Visual Studio will create a template out of the box with all required dependencies. You're now ready to start developing the triggers listening to the Service Bus topics.

Debug it simply using the CLI

Debugging the Service Bus Trigger is just simple as with every other kind of .NET solution. The local Service Bus solution will immediately listen to the selected topics.

Let’s find out about 3 interesting facts about using the Azure Service Bus:

1

Buyer- Seller Relationship

As Azure Service Bus provides a smoothest platform to receive and send messages between seller and buyer, it helps build trust through the medium of communication, messaging, between the client and the seller. Push notifications can be scheduled which informs the clients about the newly arrived stock or any newly introduced services or the notification can also be about the stock/products that have been sold out recently. This creates an understanding between both parties; seller and buyer.

2

A Flexible and Comprehensive Control

Azure Service Bus has lots of options which allows extensive control over sending the messages. Some of these options include Auto-forwarding, Scheduled delivery, Batching, Filtering and actions, and the list goes on. Auto-forwarding allows you to chain queues and message within the same namespace, and the same messages can be sent to other consumers:

Through scheduled delivery, messages can be sent at a certain time regardless of the time of their creation and scheduling. Batching also allows the delivery of messages at a certain time in bulk. Filtering gives the freedom to the subscribers to choose a specific category of messages which they want to receive and block those which they don’t want.

3

Secure Communication Despite Complex Messaging Workflows

As with Azure Service Bus, it is possible to access the assets without a network, VPN configuration, or without complex firewalls and also use the hybrid connections. This offers enhanced authentication and improved connectivity through the cloud, also the activity can be monitored easily. Azure Service Bus also makes it possible to build messaging across diverse categories of subscribers which increases the overall availability:

5 reasons why a business must exploit the benefits of the queuing mechanisms:

1

No More Long Lines

Prolonged wait times can make a considerable number of your customers turn away, which might harm the customer experience to an irreparable level. Instead, getting a queue management system by implementing queue mechanisms can save you from the pain of impaired customer service. Queue management saves your customers time and allows them to access what they need from your services/products without wasting their time. An effective and appropriate queue management stratagem reduces the on-site wait time and diminishes the number of walkaways.

2

Intensifies Staff Productivity

If the staff has to manage the long lines, it can be a massive hindrance in their way to focus on the matters that need their attention and efforts the most. As the most important and fundamental matter in business is how to satisfy the customers' needs, so you need your staff focused on and dedicated towards that goal which can only be achieved when the staff has enough time to stay dedicated and render their services with undivided attention. When a better and befitting queuing management is being operated, this gives employees an environment filled with clarity and also spreads a vibe of accomplishment among them.

3

Lesser Customer Complaints

What your customer needs to hear is what their status is about having your services or products because this makes the matters clear for your customer and they don't feel like wasting their time or left neglected. It's the customer behavior that once they get to know their place in a queue, it makes waiting time feel shorter. Queuing management strategies allow customers to use their time in an efficient manner, building up better customer experience. Resultingly, this mitigates the complaints from customers and is also a reason for reducing customer's walkways.

4

Gathers Valuable Data

The real-time data about the service/s your organization is providing, customers, and wait time assigned to these customers can be accessed easily through queuing mechanisms and management systems. The gathered data can help you identify many such areas of your services and operations where improvements are needed. Thus, the analytics can show you ways to achieve betterment and furtherance which consequently can make your business grow by leaps and bounds and gain a higher position within the market.

5

Builds a Positive Business Image

The reasons and benefits mentioned and discussed earlier in this article sum up to play a profound role in building the business image for your organization, company, or business. Better customer experience turns visitors into loyal customers, staff productivity allows innovation to flourish, and also the queue management mechanism-based system compatible with your business can lessen a great share of burden from your employees’ shoulders allowing them to do more and more in order to achieve and set their eyes on the bigger and meaningful matters.
