    Whilst Amazon S3 cloud storage is without any doubt a great solution for storing data safely in the cloud, there might be times when you require a better value alternative, be this one offering a lower cost per GB stored, better data transfer fees, different geographical areas used for storage, higher levels of data redundancy, security or other provider specific features such as easy integration with products including VPS servers or CDN networks.

    Whatever your reasons for wanting to seek alternatives beyond the official Amazon AWS S3 service are, this guide will hopefully both help in solidifying these reasons before showcasing 10 of my favourite S3 alternatives for consideration towards the end of the guide – Vamos!

    Looking for S3 compatible backup software?

    As well as S3 compatible cloud storage, if you arelooking for S3 compatible backup software then be sure to check out our guide to the best AWS S3 compatible backup software.

    Why Choose S3 Compatible Cloud Storage?

    Amazon’s AWS S3 cloud storage service has become very popular across both business and enterprise users over recent years. A big part of this success coming down to the very good levels of security, resiliency and redundancy offered by the product and how easily these features can be accessed without the need to invest in additional hardware as a user of the service.

    Not only does Amazon S3 offer a great service to business and enterprise users, but with (virtually) unlimited cloud storage available on-tap and advanced data protection features (including file versioning and file locking functionality), Amazon S3 has also become a popular service for storing backed-up data upon and is now supported by several leading backup solutions right out of the box.

    NB – For more information on choosing S3 compatible backup solutions check out our guide to S3 compatible backup software.

    Another great reason for considering AWS S3 or S3 compatible cloud storage is that it is often readily available, on demand, for both business and personal users alike. This availability means that anyone looking for cost effective cloud storage which is only billed based upon what is actually being used (alongside the other great benefits already mentioned above) should definitely consider S3 storage as an option.

    NB – Although both AWS and many other S3 compatible storage providers support a web-based file manager for accessing and managing storage, addition software supporting the S3 protocols will usually be very useful in taking full advantage of the service.

    Why Consider S3 Compatible Alternatives?

    So far, we have established that AWS S3 is a leading service which brings many benefits to the cloud storage world for both individual and business users alike. In no particular order here are some of the main reasons you might want to consider an alternative to the official Amazon AWS S3 service:

    1) Lower Storage, Egress and Ingress costs

    Whilst the official AWS S3 service is very competitive on price (especially so given it is priced on demand and that no additional hardware purchases are required), there are now a number of S3 compatible providers in the market looking to offer a similar service at a much lower cost!

    Whilst the cost of the service isn’t everything, if you are happy to use an S3 compatible service which might not have the full range of AWS functionality available, then such storage could be obtained at a much lower cost. For example, our current top S3 compatible choice, Backblaze B2, offers S3 compatible storage at approximately 76% less cost (and with approximately 80% lower egress costs) versus the official AWS S3 service!

    2) Ease of Use

    Whilst the official AWS service is undoubtedly very powerful, the sheer number of features and configuration options available could make configuring AWS S3 storage a daunting task for many, especially so individual or small business users who don’t have easy access to professional IT support to assist with the set-up of such services.

    With this in mind, many S3 compatible services (often by virtue of them offering less functionality than AWS do overall) tend to have easier to understand systems and this can in-turn often make the process of setting up such storage considerably easier as a result. One relative newcomer to the S3 compatible market space, iDrive e2, which I tested earlier this year is particularly impressive not only for its low costs but for how easy and accessible they make S3 compatible storage to obtain.

    3) Integration with other services

    Whilst AWS is a very comprehensive service in and of itself, it might often be the case that individuals or business users are already making use of another cloud provider yet still require an S3 compatible service. In cases such as these, it might be worth considering S3 compatible services from other cloud providers given the additional integration options they could already provide with any existing cloud providers (as well as the saving in time when only having to deal with a single company for any issues relating to billing and support).

    A great example of this integration is via the Spaces S3 compatible storage service from virtual server specialists, DigitalOcean. Not only is the Spaces service a great S3 compatible service in and of itself, but by being integrated into the DigitalOcean ecosystem it naturally becomes a great choice for any individuals or business already making use of DigitalOcean and its cloud services.

    S3 Alternatives - FAQs

    S3 compatibility simply refers to the cloud storage in question supporting the S3 APIs. Such storage should naturally be compatible with any applications or services already making use of S3 compatible storage via AWS themselves or another S3 compatible storage provider.

    Whilst it is important to note that prices are always subject to change and new providers can come and go, two are the best value S3 compatible alternatives we are aware of at time of publishing this guide are iDrive e2 at $0.004 / GB per month and Backblaze B2 at $0.005 / GB per month.

    Yes, in-fact if you are willing to forgo some of the niceties found in more traditional cloud backup software then making use of an S3 compatible service can help to prove one of the most cost-effective methods for creating cloud backups. Be sure to check out our guide to S3 compatible backup software for some more information on available backup software products supporting the S3 protocols.

    Yes, storage aside, one of the many additional benefits of the official AWS S3 cloud storage service is that it can also be configured to host static websites.
