Welcome to Managing Azure Service Bus. In this lesson, take a look at the tools that can be used to create and manage Azure Service Bus queues, including the Azure portal, Azure PowerShell, Azure CLI, Azure SDKs, and REST API.

The Azure Portal provides a graphical user interface for managing Service Bus entities, including queues, topics, subscriptions, and filters. Through the Azure portal, you can create, configure, monitor, and troubleshoot Azure Service Bus resources, such as queues, topics, subscriptions, and filters.

To manage Azure Service Bus via the Azure portal, you can navigate to the Service Bus namespace or resource group that contains your Service Bus resources. From there, you can create new Service Bus resources or configure existing ones, such as setting access policies, configuring messaging and filtering rules, and monitoring metrics and logs. The Azure portal provides a user-friendly interface for managing Service Bus resources, with helpful tooltips and documentation to guide you through the process.

However, it is worth noting that managing Azure Service Bus via the Azure portal may not be the most efficient way for managing large-scale and complex Service Bus deployments. For such scenarios, using Azure PowerShell, Azure CLI, or REST API may provide better automation and scalability options.

Azure PowerShell provides cmdlets to manage Service Bus resources, such as creating and deleting namespaces, topics, and queues, as well as managing access policies and keys. Additionally, Azure Resource Manager templates can be used with Azure PowerShell to define Service Bus resources and deploy them to Azure.

You can manage Azure Service Bus with Azure CLI with a variety of cmdlets. For example, Get-AzServiceBusNamespace retrieves information about a Service Bus namespace, including the name, resource group, location, status, and associated authorization rules.

The New-AzServiceBusNamespace command creates a new Service Bus namespace with the specified name, resource group, and location. Remove-AzServiceBusNamespace removes a Service Bus namespace and all associated resources, including queues, topics, subscriptions, and authorization rules.

And Set-AzServiceBusNamespace updates the properties of a Service Bus namespace, such as the default authorization rule or maximum allowed size.

Azure SDKs can also be used to manage Azure Service Bus. There are several SDKs available for .NET, Java, Python, Node.js, and other programming languages. These SDKs provide a set of libraries and tools to interact with Azure Service Bus, including managing entities such as queues, topics, and subscriptions, sending and receiving messages, and setting up authorization and authentication.

To get started with Azure Service Bus and SDKs, you need to install the appropriate SDK for your programming language and platform. For .NET, you can use the Azure.Messaging.ServiceBus or Microsoft.Azure.ServiceBus SDKs, both of which can be installed via NuGet. These SDKs provide a set of classes and methods to interact with Service Bus entities, and can be used to authenticate with Service Bus using Azure Active Directory (Azure AD).

Azure SDKs can also be used to improve the performance of Azure Service Bus, as they allow for better message batching and parallel processing. In addition, SDKs provide an HTTP pipeline with custom policies, error handling, and distributed tracing capabilities, making it easier to develop and debug applications that interact with Service Bus.

Azure Service Bus can be managed using the Service Bus REST API, which provides a set of HTTP operations for managing Service Bus resources. The API can be used to create and manage queues, topics, subscriptions, and rules, as well as send and receive messages. The API supports OAuth authentication with Azure AD, which provides superior security and ease of use over shared access signatures (SAS). With Azure AD, there is no need to store tokens in your code and risk potential security vulnerabilities.

So, the key takeaway here is that there are several tools available to manage Azure Service Bus, including the Azure portal, Azure PowerShell, Azure CLI, Azure SDKs, and REST API. 

The Azure portal provides a user-friendly graphical user interface, but may not be the most efficient option for large-scale and complex Service Bus deployments. Azure PowerShell and Azure CLI offer automation and scalability options, while Azure SDKs provide libraries and tools to interact with Service Bus entities, improving performance and enabling better message batching and parallel processing. Finally, the Service Bus REST API supports OAuth authentication with Azure AD, providing better security and ease of use over shared access signatures.
