Understanding Azure Subscription Limits and Resource Management

Azure subscription limits can be a bit overwhelming, especially for beginners.

The maximum number of subscriptions allowed per Azure Active Directory (AAD) tenant is 10,000.

As your organization grows, managing multiple subscriptions can become a challenge.

Each subscription has a unique identifier, known as a subscription ID, which is used to track and manage resources.

Azure Resource Manager (ARM) provides a centralized platform for managing resources across subscriptions.

Azure Resource Management plays a crucial role in managing your cloud IT practice in Microsoft Azure. Familiarizing yourself with the core building blocks of Azure objects, including Accounts, Tenants, and Management Groups, is essential for efficient and cost-effective resource management.

Azure Resources are the foundation of your cloud infrastructure, and understanding how they interact with each other is vital. The hierarchy of Azure objects, starting from the Azure account/tenant/directory, sets the stage for effective resource management.

To effectively manage your Azure Resources, it's essential to organize them into logical groups, such as Resource Groups, which can contain related resources like virtual machines, storage accounts, and databases. This structure helps you manage and monitor your resources more efficiently.

The Resource Manager is a crucial component of Azure Resource Management. It allows you to combine multiple resources into a single Azure Resource Group.

Resource groups provide an easy way to organize, view, and manage resources in Azure. This is especially useful for complex, multi-component applications that require a logical grouping of resources.

Resources in a resource group are not billing units, and you can't view the cost associated with a resource group from an Azure invoice. However, you can view resource usage by resource group from Azure Cost Management.

The Resource Manager also helps with limits and quotas. For example, core quotas are per-region accessible by your subscription, and you need to request a quota increase specifically for each region you want to use.

Here's a summary of the limits and quotas:

This means you need to request a quota increase specifically for each region you want to use, rather than having a single quota increase for your entire subscription.

Understanding the Microsoft Object Hierarchy is essential for efficient Azure Resource Management.

At the core of Azure is the account/tenant/directory structure.

A Microsoft Azure account is the foundation of your cloud IT practice.

There are several core building blocks to familiarize yourself with, including Accounts, Tenants, Management Groups, Subscriptions, Resource Groups, Resources, and Billing options.

These building blocks interact with each other to form the hierarchy of Azure objects.

To build a cost-effective cloud IT practice, it's crucial to understand how these components work together.

Azure Resource Graph limits the number of requests to its operations, so it's essential to monitor your usage to avoid hitting the limit.

The limit is separate from Azure Resource Graph throttling limits, which are also in place to prevent overwhelming the system.

Azure Resource Graph sets its own limit and reset rate, which can be found in the Resource Graph throttling headers for more information.

Resource Graph throttling headers provide valuable insights into remaining requests and how to respond when the limit is reached, making it easier to manage your usage.

Network and connectivity limits are in place to prevent abuse and ensure a smooth experience for all users. Specifically, the Microsoft.Network resource provider has a write/delete (PUT) limit of 1000 operations per 5 minutes.

To give you a better idea of these limits, here's a breakdown of the throttling limits for Microsoft.Network:

These limits help maintain a balanced and efficient network environment.

Network throttling is a real thing, and it's essential to know the limits. The Microsoft.Network resource provider has a specific limit on the number of writes or deletes (PUT) you can make in a 5-minute window, which is 1000.

To put that into perspective, if you're working on a project that requires frequent updates, you'll need to pace yourself to avoid hitting this limit. This is especially important if you're working on a large-scale project.

The read limit, on the other hand, is much higher, with 10,000 GET requests allowed in the same 5-minute window. This is likely because reads are typically less resource-intensive than writes.

Here's a quick summary of the limits:

Keep in mind that these limits apply to the Microsoft.Network resource provider, and you should also check the usage limits for Azure DNS for further details.

OpenAI Instance Connectivity is a crucial aspect of network and connectivity.

To connect to an OpenAI instance, you need to have a valid API key, which can be obtained by signing up for an OpenAI account.

The API key is used to authenticate and authorize access to the OpenAI instance.

OpenAI instances can be connected using various protocols, including HTTP and WebSocket.

These protocols enable real-time communication and data exchange between the client and the OpenAI instance.

With OpenAI instance connectivity, you can access a range of services, including text generation, translation, and conversation.

These services can be integrated into various applications, such as chatbots, virtual assistants, and language translation software.

Azure services have their own set of limits, which can vary depending on the service. Some services have adjustable limits, while others do not.

If a service has adjustable limits, you can raise the limit above the default limit, but not above the maximum limit. The default and maximum limits are usually listed in the service's documentation.

To request a quota increase, you'll need to specify the amount and region you want to increase the limit for. For example, if you need 30 vCPUs in West Europe, you'll need to request a quota increase specifically for that region.

Azure Communications Gateway has default limits and quotas that can be increased by creating a change request stating the specific limit you want to change.

Some of these limits can be adjusted, so it's worth exploring what's possible.

Azure Communications Gateway also has limits on the SIP signaling, which is a key aspect of its functionality.

The size of SIP messages is restricted, but the exact limits are not specified in the documentation, so you'll need to refer to the [communications-gateway-sip-size-restrictions] for more information.

By understanding these limits, you can better plan and manage your Azure Communications Gateway resources.

Azure Storage is a crucial component of Azure Services, and understanding its limits is essential for optimal performance and cost-effectiveness.

Azure Storage has various limits depending on the type of storage you're using, including Standard storage account limits, Azure Storage resource provider limits, Azure Blob Storage limits, Azure Queue storage limits, and Azure Table storage limits.

Storage throttling is another important aspect to consider, especially when performing management operations using Azure Resource Manager with Azure Storage. Here are the limits per region of the resource in the request:

Virtual Machine disk limits also apply, and they vary depending on whether you're using Standard or Premium storage accounts.

API Management Tiers are a crucial aspect to consider when working with Azure API Management. API Management classic tiers exist, which is a fundamental fact to keep in mind.

API Management v2 tiers are also available, offering a different set of features and limitations. These tiers are a significant improvement over the classic tiers, but still have their own set of limits.

API Management workspaces are a separate entity, with their own set of limits and features. They provide a way to organize and manage multiple API Management instances.

The Developer portal is a key feature in API Management v2 tiers, allowing developers to easily access and manage APIs. However, it's worth noting that the Developer portal is only available in API Management v2 tiers.

Here's a summary of the main API Management tiers and their key features:

App Configuration is a service that allows you to store and manage application settings in a centralized location.

You can use App Configuration to store secrets, such as API keys and connection strings, securely.

Each Azure subscription has a default App Configuration instance, which can be accessed through the Azure portal.

The default instance has a limit of 100,000 keys, which can be increased as needed.

App Configuration supports multiple data stores, including Azure Blob Storage and Azure Cosmos DB.

The service also provides a built-in audit log, which can be used to track changes to application settings.

App Configuration supports both HTTP and HTTPS protocols for secure communication.

The service is designed to be highly available and scalable, with built-in support for load balancing and failover.

Synapse Analytics is a cloud-based enterprise data warehouse that allows you to integrate and analyze data from various sources.

You can use Synapse Analytics to query data in Azure Storage and Azure Cosmos DB, and even connect to on-premises data sources using PolyBase.

Synapse Analytics supports a wide range of data types, including relational, NoSQL, and semi-structured data.

With Synapse Analytics, you can create data warehouses in minutes, and scale as needed without worrying about infrastructure management.

Synapse Analytics provides a unified view of your data, making it easier to analyze and gain insights from your data assets.

Azure Service-Specific Limits are in place to ensure fair usage and prevent abuse of the platform.

Azure has limits in place for various services, including Active Directory, API Management, App Service, and more. These limits can be found in the Azure documentation.

Some of the services with limits include:

Azure AI services have limits to ensure a high-quality experience for all users.

The Provisioning API has limits that you should be aware of.

To use the Provisioning API, you need to know its limits, which include the maximum number of requests per minute and the maximum number of entities that can be updated or deleted in a single request.

Azure AI services are designed to handle a large volume of requests, but there are still limits to prevent abuse and ensure fair usage.

The Provisioning API limits are in place to prevent abuse and ensure fair usage, so it's essential to understand these limits before using the API.

Azure Functions limits are quite specific, and you can learn more about them by checking out Billing accounts and scopes in the Azure portal.

To get started with Azure Functions, you'll want to be aware of the creation limits for Azure subscriptions.

Azure Functions can be a powerful tool, but it's essential to understand the limits to avoid any potential issues.

The creation limits for Azure subscriptions are outlined in Billing accounts and scopes in the Azure portal.

Scale Sets are a great way to manage your resources in Azure, but did you know that Virtual Machine Scale Sets have limits? For example, Virtual Machine Scale Sets limits exist.

You can find more details on Virtual machine sizes in the documentation, which is a good place to start if you're looking to optimize your scale sets.

The Managed Run Command limit is a key consideration for Azure users. The maximum number of allowed Managed Run Commands is currently limited to 25.

If you're planning to use Managed Run Commands extensively, you'll need to keep this limit in mind to avoid hitting the cap.

Azure Security and Access is a vital aspect of managing your subscription limits. Azure Active Directory (Azure AD) is the core service for identity and access management in Azure, allowing you to manage access to your Azure resources.

Azure AD provides a range of features to ensure secure access, including multi-factor authentication, conditional access, and identity protection. This helps prevent unauthorized access to your Azure resources.

To manage access to your Azure resources, you can use Azure AD groups to assign permissions and roles to users. This makes it easier to manage access and ensure that only authorized users can access sensitive resources.

Microsoft Tenants are the core building blocks of Azure, and understanding them is crucial for efficient cloud IT practice.

An Azure account is essentially a Microsoft Tenant, which is a unique identifier for your organization.

Familiarizing yourself with the hierarchy of Azure objects is the first step to determining the most efficient and cost-effective way to build a cloud IT practice in Microsoft Azure.

A Microsoft Tenant is a single directory that contains all the resources and subscriptions for your organization.

To build a cloud IT practice in Microsoft Azure, you need to understand the hierarchy of Azure objects, starting with the core building blocks of Accounts, Tenants, Management Groups, Subscriptions, Resource Groups, Resources, and Billing options.

Azure resources are organized into Resource Groups inside a subscription, and every resource must be deployed in a geographical location known as a Region.

There are over 60 regions available in 140 countries, and Microsoft is constantly growing its global footprint.

Azure regions are groupings of data centers located in specific geographic locations, and resources deployed in the same region are interconnected with high-speed connectivity.

Resources in different regions can still communicate with each other over Microsoft’s dedicated network, but are subject to additional WAN latency.

The latency depends on how far the regions are from each other, and resources in different regions are subject to additional WAN latency.

Billable Azure resources have a Meter attached to them that runs while the resource is provisioned, and there are both billable and non-billable resources.

Azure RBAC limits are in place to prevent abuse and ensure secure access to resources. The limits apply to Azure role-based access control (Azure RBAC).

Azure RBAC has specific limits to prevent over-privileging and ensure secure access to resources. These limits are designed to prevent abuse and ensure that users have only the necessary permissions.

The following limits apply to Azure RBAC: [!INCLUDE role-based-access-control-limits].

Azure Active Directory is a cloud-based identity and access management solution that integrates with Microsoft Azure. It provides a centralized location for managing user identities, groups, and applications.

Azure Active Directory can be used to manage access to Azure resources, such as virtual machines and storage accounts, as well as on-premises resources using Azure Active Directory Domain Services. This allows for a single identity and access management system across both cloud and on-premises environments.

With Azure Active Directory, organizations can use multi-factor authentication to add an extra layer of security to their user authentication process. This can be set up to require a second form of verification, such as a code sent to a user's phone or a biometric scan, in addition to their username and password.

Azure Active Directory also supports conditional access policies, which allow organizations to control access to their resources based on user identity, device, location, and other factors. This can be used to block access to sensitive resources from untrusted devices or locations.

The new throttling experience is a game-changer for Azure users. You can send more requests, which is a big plus.

Write requests increase by 30 times, making it easier to accomplish tasks. This is a significant boost in productivity.

Delete requests increase by 2.4 times, allowing you to manage your data more efficiently. You'll be able to delete more files and data in less time.

Read requests increase by 7.5 times, making it faster to retrieve the information you need. This is especially helpful when working with large datasets.
