Azure storage account IaaS or PaaS

Hi,

Azure storage account is IaaS or PaaS?
As I understand it can be categorised under both IaaS and PaaS, depending on the use case.

For example, in this qa:
Your company plans to migrate all its data and resources to Azure.

The company’s migration plan states that only platform as a service (PaaS) solutions must be used in Azure.

You need to deploy an Azure environment that supports the planned migration.

Solution: You create an Azure App Service and Azure Storage accounts.

Does this meet the goal?

So, here how can I know if it will be used as IaaS or PaaS without more information about how the company are planning to use this server

Azure Storage
Azure Storage

Globally unique resources that provide access to data management services and serve as the parent namespace for the services.

    Hello ABOD

    Thank you for your question!

    Please be informed that Azure Storage accounts can be categorized as both IaaS and PaaS, depending on the specific storage service being used within the account and the way it's consumed.

    App Services commonly use Blob Storage for things like static website content, images, user-uploaded files, or logs. Blob Storage is a pure PaaS offering. They might also use Azure Files for shared content that multiple instances need to access, which is also a PaaS offering.

    Yes, creating an Azure App Service and Azure Storage accounts does meet the goal of using only PaaS solutions in this context. The storage accounts are implicitly assumed to be used for their PaaS features (like Blob storage or Azure Files) to support the App Service, rather than for IaaS components like virtual machine disks.

    So, (Azure App Service and Azure Storage Accounts) meets the goal of using only PaaS solutions, as Azure Storage Accounts are classified as PaaS unless explicitly used for IaaS workloads like VM disks. Without additional details suggesting an IaaS use case, assume PaaS for Azure Storage Accounts.

    Hope the above answer helps! Please let us know do you have any further queries.

    Yep - the classification of Azure Storage as IaaS or PaaS does depend to some extent on the context.

    By default, Azure Storage is considered a PaaS offering.

    • Azure Storage (Blobs, Tables, Queues, Files, Disks) provides managed services for storing data.
    • You don’t manage the underlying infrastructure like disks, file systems, or VMs.
    • Microsoft handles scalability, availability, and maintenance.
    • You access it via APIs, SDKs, or through higher-level services.

    IaaS storage typically refers to attaching managed disks to VMs, where the VM and its OS are managed by you (like in a typical IaaS deployment).

    So, in your scenario:

    "You create an Azure App Service and Azure Storage accounts." "The company’s migration plan states that only PaaS solutions must be used in Azure." "Does this meet the goal?"

    My take would be that this does meet the goal:

    • Azure App Service is clearly a PaaS offering.
    • Azure Storage Account (used for Blob, Queue, Table, File, etc.) is also PaaS, unless you're specifically attaching it as a disk to an IaaS VM (which is not the case here).

    On the other hand, note that sometimes you might also see references to Azure Storage as IaaS because it's one of thee "infrastructure building block" of Azure solutions (in addition to compute and networking) - but I don't believe this would apply in this context.
