Amazon S3 and Microsoft Azure Object Storage compete in the cloud storage solutions category. Amazon S3 has the upper hand in data retrieval speed and global reach, while Azure Object Storage is superior in integration with other Microsoft services and customer support.
Features: Amazon S3 offers extensive scalability, superior durability, and robust security measures. Microsoft Azure Object Storage integrates seamlessly with other Azure services, provides strong analytical capabilities, and offers flexible data management.
Room for Improvement: Users suggest Amazon S3 should simplify its complex pricing model, reduce the user learning curve, and improve customer support. Microsoft Azure Object Storage needs better performance in data retrieval speed, greater transparency in pricing, and simplified deployment processes.
Ease of Deployment and Customer Service: Amazon S3 has a straightforward deployment process but mixed reviews on customer support. Microsoft Azure Object Storage has a steeper deployment but highly rated customer service.
Pricing and ROI: Amazon S3 users appreciate competitive setup costs and good ROI but criticize the unpredictable pricing model. Azure Object Storage offers competitive pricing and high ROI with transparent costs, making it preferable for cost-sensitive users.
Moving infrequently accessed data to cheaper classes like Glacier is beneficial for long-term storage at a lower cost.
I have seen a return on investment, and the ROI that we observed in our organization includes reducing manpower by 20% and achieving zero downtime for storage expansion, which improves overall productivity.
Amazon S3 has a reasonable price as you pay a flat price to use it.
I have seen a return on investment as it saves both time and money with this agile technology.
I rate the technical support from Amazon for S3 a ten out of ten.
The customer support for Amazon S3 is very good; they are responsive and knowledgeable, providing quick resolutions, clear documentation, and proactive guidance during migrations or performance tuning.
An engineer is assigned based on the severity of the issue.
If I want to change something on my resources or directly access it via the portal, there is not a service level agreement of 100%, and sometimes it's quite difficult to access.
The customer support for Microsoft Azure Object Storage is not good.
Technical support from Microsoft is good.
Data placed in an S3 bucket is replicated across availability zones in a region, ensuring scalability and availability.
The level of scalability allows storage to automatically scale on demand, without the need for manual intervention.
The scalability of Amazon S3 is excellent as it handles unlimited data and seamlessly supports growth without manual provisioning or performance degradation.
The storage is very scalable, so you can effortlessly scale it.
The downloading of high volume data and scalability processes face performance issues related to high data volumes.
Most of the time, it fits the requirement, but for drastic demands, we may need to provide quotas and other requirements to Microsoft for them to manage forecast and capacity planning.
There is zero latency or downtime.
Transitioning between S3 storage classes, like moving data from the standard class to Glacier or Glacier Deep Archive, has been challenging.
Amazon S3 is highly stable.
The downloading of high volume data and scalability processes face performance issues related to high data volumes.
From a security standpoint, there is a question mark due to past cyber attacks.
An improvement could be associating the naming with personal accounts, allowing more familiar or desired names without conflicting with global conventions.
The practice of protecting data could be more streamlined or mandatory.
I would like to see an increase in the data upload limit, similar to DynamoDB, where there is no data limit.
When using Data Lakes for analytics and frequently pulling data from our source database to Microsoft Azure Blob Storage, there should be faster methods to download large data from Microsoft Azure Storage Blob to different locations.
They need enhancement in security aspects. Security alerts and integrations could be improved as part of lifecycle management, especially for archives and restoration requirements.
The improvement needed for Microsoft Azure Object Storage is to reduce the transactional charges, as these read and write operation charges are higher.
I've used the free tier and haven't been charged yet.
S3 offers multiple classes, allowing you to move data to cheaper classes for cost savings.
Since using Amazon S3, storage costs have reduced by around 35% to 40% through lifecycle tiering.
It's a pay-per-use solution and a good idea for proof of concept and value.
The licensing cost of Microsoft Azure Object Storage is cheaper compared to other competitors, such as Google or third-party solutions, which easily engages customers.
Regarding pricing for Microsoft Azure Object Storage, I find it reasonable.
Its stability and scalability are also impressive, as it allows for increased storage space according to demand.
I appreciate its capability to create static websites and integrate with services like CloudFront, EC2, and DynamoDB.
Security measures like encryption, access controls, and the block public access feature are also important.
Since I work mostly with AI/ML, data piping, data integrations, and ETL tools, these features are valuable.
When talking about storage accounts, customers utilize Azure file as a replica of the file server, allowing them to access file shares or storage accounts from their systems, making it easy to use while automatically syncing data with the cloud.
The ability to store everything inside Blob or Object storage and use it for archiving data is beneficial.

Amazon Simple Storage Service is storage for the Internet. It is designed to make web-scale computing easier for developers.
Amazon S3 has a simple web services interface that you can use to store and retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, fast, inexpensive data storage infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to developers.
