    I think [Amazon S3 (Simple Storage Service)] is cheaper than Azure Blob Storage (at least at the time I selected it). It is a low maintenance product and it is more reliable.

    We are an AWS shop, thus it is much easier to use with other AWS services. It may not always be the cheapest but once you are in AWS if you can decouple your apps and use this as one of your services it will certainly make developer's life easier and admin life easier.

    Amazon S3 is a great service to safely backup your data where redundancy is guaranteed and the cost is fair. We use Amazon S3 for data that we backup and hope we never need to access but in the case of a catastrophic or even small slip of the finger with the delete command we know our data and our client's data is safely backed up by Amazon S3. Transferring data into Amazon S3 is free but transferring data out has an associated, albeit low, cost per GB. This needs to be kept in mind if you plan on transferring out a lot of data frequently. There may be other cost effective options although Amazon S3 prices are really low per GB. Transferring 150TB would cost approximately $50 per month.

    Blob storage is well suited to hosting/sharing zipped files rather than several smaller files, as folder enumeration/listing is not supported. Files uploaded are case-sensitive, so users need to be educated on the correct naming convention format if they are delegating the file-sharing process outside of IT.

    Pros
    Amazon AWS
    • Fantastic developer API, including AWS command line and library utilities.
    • Strong integration with the AWS ecosystem, especially with regards to access permissions.
    • It's astoundingly stable- you can trust it'll stay online and available for anywhere in the world.
    • Its static website hosting feature is a hidden gem-- it provides perhaps the cheapest, most stable, most high-performing static web hosting available in PaaS.

    Cons
    Amazon AWS
    • Web console can be very confusing and challenging to use, especially for new users
    • Bucket policies are very flexible, but the composability of the security rules can be very confusing to get right, often leading to security rules in use on buckets other than what you believe they are

    • If we are transferring huge amount of data (outbound), it can get quite expensive.
    • With new features being added constantly, although a good thing, at times it becomes difficult to keep up with the changes. Documentation needs to keep UpToDate and should include best practices.
    • Performance can be improved especially when it comes to cold storage.

    Amazon AWS
    It is tricky to get it all set up correctly with policies and getting the IAM settings right. There is also a lot of lifecycle config you can do in terms of moving data to cold/glacier storage. It is also not to be confused with being a OneDrive or SharePoint replacement, they each have their own place in our environment, and S3 is used more by the IT team and accessed by our PHP applications. It is not necessarily used by an average everyday user for storing their pictures or documents, etc.

    Blob storage is fairly simple, with several different options/settings that can be configured. The file explorer has enhanced its usability. Some areas could be improved, such as providing more details or stats on how many times a file has been accessed. It is an obvious choice if you're already using Azure/Entra.

    AWS has always been quick to resolve any support ticket raised. S3 is no exception. We have only ever used it once to get a clarification regarding the costs involved when data is transferred between S3 and other AWS services or the public internet. We got a response from AWS support team within a day.

    Microsoft has improved its customer service standpoint over the years. The ability to chat with an issue, get a callback, schedule a call or work with an architecture team(for free) is a huge plus. I can get mentorship and guidance on where to go with my environment without pushy sales tactics. This is very refreshing. Typically support can get me to where I need to be on the first contact, which is also nice.

    Overall, we found that Amazon S3 provided a lot of backend features Google Cloud Storage (GCS) simply couldn't compare to. GCS was way more expensive and really did not live up to it. In terms of setup, Google Cloud Storage may have Amazon S3 beat, however, as it is more of a pseudo advanced version of Google Drive, that was not a hard feat for it to achieve. Overall, evaluating GCS, in comparison to S3, was an utter disappointment.

    Azure Blob Storage is the best choice to store files when the app runs in Azure. It also has some advantages over S3, like Shared Access Signatures, that make it easy to control access to files directly via a URL. Azure Blob Storage is very fast and we have not had any major issues with it after using it for several years.

    Return on Investment
    Amazon AWS
    • It practically eliminated some real heavy storage servers from our premises and reduced maintenance cost.
    • The excellent durability and reliability make sure the return of money you invested in.
    • If the objects which are not active or stale, one needs to remove them. Those objects keep adding cost to each billing cycle. If you are handling a really big infrastructure, sometimes this creates quite a huge bill for preserving un-necessary objects/documents.
