Azure Storage Account Limits and Options Explained

In Azure, Storage Account limits are essential to consider when deciding on the right storage solution for your application.

The maximum storage capacity for a single Azure Storage Account is 5 TB, which is a generous amount, but may not be enough for large-scale applications.

You can have multiple Storage Accounts, which can help you scale up your storage needs.

Azure offers a variety of storage options, including Blob, File, Queue, and Table storage, each with its own set of limits and use cases.

Blob storage, for example, allows for up to 20,000 blobs per container, which is a good starting point for most applications.

File storage, on the other hand, has a limit of 5,000 files per share, which may be a constraint for applications with a large number of files.

Azure Storage Account limits are not just about storage capacity, but also about performance and scalability.

You can store files up to 4.77 TB in size, which is huge! The maximum size of a single file is determined by the block blob type, which we'll get to in a minute.

There are three types of Azure Blob Storage: block blobs, append blobs, and page blobs. Each type has its own strengths and weaknesses.

Block blobs are great for storing files that won't be updated after they're uploaded. They're split into small parts called blocks, which are then merged into a single unit. This means you can't modify the file once it's uploaded.

Append blobs are optimized for storing metadata and logs. You can update files without re-uploading them, making them perfect for database log files.

Page blobs are used for frequent/fast read and write operations. They're made up of 512-byte pages, and the maximum blob size is 1 TB.

You can only select a blob type once when creating the blob, and you can't change it later. However, you can switch between access tiers when needed, except for page blobs.

Azure Blob Storage is often used as a backup destination, which is integrated into modern data protection solutions. You can even use it to send VMware vSphere backups to Azure Blob storage with NAKIVO Backup & Replication.

Here are the three access tiers for Azure Blob Storage:

Remember, the correct tier will help you optimize storage costs. You should define how frequently you'll access the data and how long it must be retained before selecting a tier.

File Storage is a key component of Azure Storage Account, allowing you to store files in the cloud. You can create a file share in Azure cloud and store files up to 1 TB in size.

Azure File Storage supports SMB and NFS file shares, making it easy to access shared files from Azure virtual machines or local machines. You can also store backups in Azure File Storage.

There are four component types for file storage in Azure: Azure storage account, Share, Directory, and Files. The share name must be 3 to 63 characters long.

Here's a breakdown of the file storage pricing:

To organize your files, Azure file storage supports a hierarchical directory structure with subdirectories and files. You can upload files up to 1 TB in size.

Azure file storage pricing is based on data storage and operations. For data storage, you pay $0.06 per used GB for file storage and snapshots. Here's a breakdown of the costs:

For operations and data transferring, you pay $0.015 per 10,000 operations for Put, Create Container, and List operations. All other operations, except Delete, cost $0.0015 per 10,000 operations.

Azure Disk Storage offers three types of disks for virtual machines: OS disk, data disk, and temporary disk. Each disk serves a specific purpose.

The OS disk contains the operating system files and has a maximum capacity of 2,048 GB. This disk is fixed when you create a virtual machine, and it's used to boot the machine.

Data disks are used to store data, such as database files, website static content, or custom application code. The number of data disks you can add depends on the virtual machine size. Each data disk has a maximum capacity of 32,767 GB.

Temporary disks are used for short-term storage applications, like page files and swap files. The contents of temporary disks are lost during maintenance events, so don't use them for critical data. Temporary disks are local to the server and not stored in a storage account.

Here's a quick rundown of the three types of disks:

Azure Storage offers a range of storage services to meet different needs.

Azure Storage provides an enormously scalable object store for data objects, disk storage for Azure virtual machines (VMs), a file system service for the cloud, a messaging store for reliable messaging, and a NoSQL store.

Azure Storage supports five main data services: Azure Blobs, Azure Files, Azure Queue, Azure Tables, and Azure Disks.

Here are the five core data services offered by Azure Storage:

Data transfer is a crucial aspect of Azure Storage Accounts. It refers to the transportation of data between the Azure Storage Account and other services or resources within or outside of Azure.

Data transfers within the same Azure region are generally free. This is a great feature, especially for businesses that rely heavily on cloud storage.

The cost of data transfers varies depending on the location of the data and the type of transmission. For instance, data transfers between regions are charged, which can add up quickly.

Data transfers to and from the Internet are also costly. This is something to consider when deciding how to set up your Azure Storage Account.

In summary, data transfer costs are determined by the location and type of transfer.

Azure Blob Storage offers three access tiers: Hot, Cool, and Archive. These tiers are designed to help you optimize storage costs based on how frequently you access your data.

Hot access tier is ideal for frequently accessed data, with the highest storage cost but lowest access cost. It's perfect for applications that require rapid access to data.

Cool access tier is less expensive than the hot tier but more expensive than the cold tier to store files. It's optimized for infrequently accessed data that's stored for at least 30 days.

Data stored in the cold (archive) access tier must reside for at least 180 days to avoid early deletion charges. If you delete data earlier than 30 or 180 days for cool and cold access tiers, you'll be charged an early deletion fee.

Here's a summary of the three access tiers:

Each tier provides features to choose from depending on the lifecycle of the data stored in the Azure cloud. Selecting the correct tier will allow you to optimize storage costs.

Geo-Zone-Redundant storage is a highly reliable option that provides maximum protection against regional disasters. This is because data is synchronously replicated across three Azure availability zones in the primary region, and then asynchronously replicated to a single physical location in the secondary region.

Data is then replicated synchronously in the secondary region, resulting in three copies. This provides durability of 99.99999999999999% (99 and fourteen nines). GZRS is recommended for applications that require high levels of protection, performance, availability, and resilience.

To give you a better idea of the redundancy levels, here's a comparison of the different types of redundant storage:

This shows that GZRS provides the highest level of durability, making it an excellent choice for critical applications.

Storage Account Management is crucial to optimize your Azure experience. You can manage your storage accounts through the Azure portal, Azure CLI, or Azure PowerShell.

To create a storage account, you need to specify a unique name, which can be up to 24 characters long. This is a hard limit, not a recommended maximum.

You can also manage access to your storage account by creating access keys, which can be used for authentication with Azure services. There is no limit to the number of access keys you can create.

If the number of messages in the Storage Queue exceeds the limit that can be deleted manually, an automated task can be created to purge the Storage Queue periodically when the need is to deal with a huge volume of messages.

Creating an automated task for message purge is a great way to manage your Storage Account efficiently, especially when dealing with large volumes of messages.

You can set up the automated task to run at specific intervals, such as daily or weekly, to ensure that your Storage Queue remains within the manageable limit.

Automated tasks can help prevent Storage Queue overflow and associated issues, giving you more time to focus on other important tasks.

When choosing a storage account in Azure, you have several options to consider. Each type of account has its own unique features and pricing model, so it's essential to pick the right one for your application.

There are four main types of storage accounts available in Azure: General-Purpose v2 (GPv2), General-Purpose v1 (GPv1), Blob Storage Accounts, and Premium Storage Accounts. GPv2 accounts support blobs, files, queues, tables, and drives, making them a great option for most scenarios.

General-Purpose v1 accounts are a legacy type and should be avoided unless necessary. They support blobs, files, queues, and tables, but not drives. Blob Storage Accounts are ideal for storing massive amounts of unstructured data, such as photographs, videos, and documents.

Premium Storage Accounts are designed for high-performance, low-latency workloads that require constant performance and minimal I/O latency. They support both managed and uncontrolled disks.

Here's a quick summary of the main differences between Azure's storage account options:
