Azure Storage vs GCP Storage: A Technical Deep Dive


Choosing the right cloud storage service requires an understanding of your needs and the technical capabilities of each platform. In this article, we delve into the specifics of Azure and Google Cloud Platform (GCP) storage services, providing a detailed comparison to help inform your decision.

Azure Storage: An In-depth Look

Azure Storage provides a range of services, each designed to accommodate specific storage needs. Let’s take a closer look at each service.

Blob Storage

Azure Blob Storage is designed for storing massive amounts of unstructured data, such as text or binary data. It includes three types of blobs: block blobs for handling data up to about 4.7 TB, append blobs for append operations like logging, and page blobs for random read/write operations and providing the backbone of Azure IaaS Disks.

Disk Storage

Azure Disk Storage provides disks for Azure Virtual Machines (VMs), offering high-performance SSD and low-cost HDD options. It also allows for snapshot creation and disk cloning.

File Storage

Azure File Storage offers fully managed file shares in the cloud accessible via the industry-standard SMB protocol. Azure Files can be used to replace or supplement on-premise file servers or NAS devices.

Table Storage

Azure Table Storage is a service that stores structured NoSQL data in the cloud, providing a key-attribute store with a schemaless design. Azure Table Storage is ideal for storing structured, non-relational data, and is highly scalable.

Queue Storage

Azure Queue Storage is a service for storing large numbers of messages that can be accessed from anywhere in the world via authenticated calls using HTTP or HTTPS. It’s often used to create a backlog of work to process asynchronously.

GCP Storage: An In-depth Look

Much like Azure, Google Cloud Platform (GCP) also offers various storage services, designed to cater to a range of different needs.

Cloud Storage

GCP Cloud Storage is an object storage service comparable to Azure’s Blob Storage. It’s designed for a wide range of storage needs, from serving website content, storing data for archival and disaster recovery, to distributing large data objects to users via direct download.

Persistent Disk and Local SSD

Persistent Disk is GCP’s block storage solution, similar to Azure Disk Storage. It’s suitable for use as boot disks and data storage for virtual machine instances. GCP also offers Local SSDs for high performance, low latency use cases.


GCP Filestore is a managed file storage service comparable to Azure’s File Storage. It’s designed for applications that require a filesystem interface and a shared filesystem for data. It supports the NFS protocol.

Firestore and Bigtable

Firestore is GCP’s highly scalable, fully managed NoSQL document database, while Bigtable offers a fast, fully managed, massively-scalable NoSQL database service. Both these services can be compared to Azure’s Table Storage.

Direct Comparison: Azure vs GCP

Now that we’ve broken down the different services offered by Azure and GCP, let’s look at how they compare.

Azure Storage
GCP Storage
Object StorageAzure Blob Storage is a versatile and highly scalable solution designed specifically for handling massive volumes of unstructured data, be it text or binary data. With its three types of blobs – block, append, and page – Azure Blob Storage is engineered to cater to diverse needs, including handling streaming and batch data, storing backups, and providing the backbone of Azure IaaS Disks.GCP Cloud Storage is Google’s counterpart for Azure Blob Storage, offering similar capabilities for unstructured data storage. GCP Cloud Storage sets itself apart with its four distinct storage classes – Standard, Nearline, Coldline, and Archive, allowing you to tailor your storage solution to align with your data usage pattern and budget.
Block StorageAzure Disk Storage is your go-to service when you need persistent and high-performance disks for Azure Virtual Machines. With support for both SSD and HDD, Azure Disk Storage ensures a solution for every workload intensity. Additional features like snapshot creation and disk cloning make it a comprehensive block storage solution.GCP Persistent Disk is the block storage service in Google Cloud, designed to provide robust and reliable disk storage for GCP’s Virtual Machine instances. Similar to Azure, it supports both SSD and HDD. For workloads that require ultra-high performance with low latency, GCP also offers Local SSDs.
File StorageAzure File Storage enables fully managed file shares in the cloud, accessible via the industry-standard SMB protocol. It’s an excellent service for businesses needing to replace or supplement on-premise file servers or NAS devices, offering seamless integration and compatibility.GCP Filestore is Google Cloud’s managed file storage service for applications requiring a filesystem interface and a shared filesystem for data. It supports the NFS protocol, ensuring compatibility with a wide range of systems and applications.
NoSQL DatabaseAzure Table Storage is a NoSQL database service that excels at storing structured, non-relational data in the cloud. It’s a key-attribute store with a schemaless design, making it ideal for flexible and adaptable data storage.Google Cloud Platform offers two NoSQL database services: Firestore and Bigtable. Firestore is a fully managed NoSQL document database that is scalable and robust, ideal for storing and syncing data for serverless, cloud-native applications. Bigtable, on the other hand, is a fast, fully managed, massively-scalable NoSQL database service designed for large operational and analytical workloads.
Queue StorageAzure Queue Storage provides a secure and reliable service for storing large numbers of messages that can be accessed from anywhere in the world. It’s an excellent tool for creating a backlog of work to process asynchronously.GCP doesn’t have a direct equivalent to Azure Queue Storage. However, GCP’s Cloud Pub/Sub, in combination with Cloud Functions or Cloud Run, offers similar functionality for building and deploying event-driven systems and microservices.

Cloud Storage Costs

When evaluating cloud storage services, cost efficiency is as crucial as the technical aspects. Both Azure and GCP offer competitive pricing models, factoring in aspects such as the storage type, data access frequency, redundancy options, and region of storage. Here is a simple comparison table showcasing the starting prices of different storage services in both platforms.

Azure StorageGCP Storage
Object Storage (Cool Tier)$0.01 per GB/month$0.01 per GB/month
Block Storage (SSD)$0.073 per GB/month$0.17 per GB/month
File Storage$0.06 per GB/month$0.20 per GB/month
NoSQL Database$0.07 per 10,000 transactions$0.06 per 100,000 document reads
Queue Storage$0.0004 per 10,000 transactionsN/A
Azure vs GCP Costs

It’s worth noting that while the cost of storage services plays a role in the total cost, it’s also important to consider network and operations costs.

In the context of Azure Storage, one way to further enhance cost efficiency is by leveraging the Cloud Storage Manager software. This tool provides valuable insights into your Azure Storage usage, helping you identify areas where you can reduce costs. For instance, with Azure Files, Cloud Storage Manager can help implement strategies to save money, such as setting up quotas on file shares, deleting unused files, and using Azure File Sync.

Similarly, Azure Blob Storage users can find cost-effective tips to manage their storage better. These include finding and managing the largest blobs and minimizing Azure Blob Storage costs through lifecycle management policies and optimizing storage tiers. With the right approach and tools like Cloud Storage Manager, you can ensure you’re not overspending on your storage needs.


Azure and GCP both offer robust, scalable, and secure storage services.Continuing from the previous response:

The optimal platform for your needs depends on your specific use cases, the volume and type of data you are dealing with, and the specific requirements of your applications. Your decision may also be influenced by other factors such as pricing, the existing technological infrastructure of your company, and personal preference.


  1. How do Azure Blob Storage and GCP Cloud Storage compare in terms of performance? Both Azure Blob Storage and GCP Cloud Storage offer high durability, availability, and scalability. However, GCP offers four distinct storage classes allowing users to optimize costs based on access frequency, which could impact retrieval performance.
  2. Can Azure Disk Storage and GCP Persistent Disk be used interchangeably? While both services provide similar functionality, migrating from one to another requires careful planning due to potential changes in performance, pricing, and compatibility with specific Virtual Machines or applications.
