S3 Compatible Storage On-Prem
In the world of enterprise storage, a new hero is rising and it’s called S3 compatible storage. What started as a cloud-only wonder is now sneaking into on-premise data centers and private clouds, ready to shake things up.
The magic behind 'S3 compatible' is simple - it means the storage speaks the S3 API language fluently. If your application understands S3, it’ll work seamlessly with S3 compatible storage, like a perfect dance partner.
More and more applications are jumping on this bandwagon because S3 compatible storage has some serious perks. Here's why Rabata and others are betting on it:
- Scale: It’s built to grow without limits, all under one roof - one namespace to rule them all.
- Geo-distribution: Imagine one storage system that can stretch across multiple locations, keeping your data connected no matter where it lives.
- Cost: Designed to run on standard servers, it lets you snag the best deals and efficiency the hardware market can offer.
- Reliable data transport: Created in the internet age, S3-compatible storage excels at moving huge data mountains across wide networks without breaking a sweat.
Cloudian leads the pack in S3-compatible storage, but plenty of familiar names like Rubrik, Veeam, Commvault, Splunk, and NetApp have also embraced it. Adobe, VERITAS, Hadoop, EMC, Komprise - this list reads like the who’s who of storage and data management.
And this is just the tip of the iceberg in our deep dive into the world of S3 storage.
Clearing Up the Jargon
Now, let's demystify S3-compatible storage a bit more. This storage style carries quite a few nicknames, so keep up.
It’s often called object storage because the technology underneath organizes data as - surprise - objects. Over time, developers used various APIs to interact with object storage, but S3 API has now taken the crown as the most popular.
Sometimes you’ll hear 'cloud storage' thrown around. Most cloud storage today is actually object storage using the S3 API. So these different terms? They’re mostly describing the same great thing: S3-compatible storage.
Why Choose S3 Compatible Storage On-Prem?
Deploying S3 compatible storage right in your own data center comes with some seriously compelling perks. Imagine expanding your storage effortlessly to an exabyte scale without breaking a sweat or interrupting your workflow. That’s exactly what S3-compatible solutions bring to the table - a single namespace that grows with your needs, no fuss involved.
Think of the cost savings like finding a hidden treasure. On-prem S3 storage often costs up to 70% less than public cloud options. This isn’t magic - it’s thanks to using industry-standard hardware that packs more data into less space and slashes your per-GB expenses. Plus, there’s no sneaky ingress or egress fees draining your budget.
When speed matters, keeping your storage close by matters even more. Hosting your hardware inside your data center means you get lightning-fast response times and plenty of bandwidth. No more waiting around as your data zips back and forth across the internet.
Security-conscious folks will appreciate the peace of mind that comes with having full control. Your data stays safely behind your firewall, letting you enforce security policies and manage access exactly how you want. No surprises, no backdoors.
Flexibility is another big win here. Since S3 is the common language between on-prem storage and public clouds, you’re never locked in. You can start using cloud resources seamlessly when needed and tap into the ever-growing ecosystem of S3-compatible apps without missing a beat. Moving data and apps between your servers and the cloud becomes a smooth, hassle-free dance.
- Scale effortlessly to an exabyte in a single namespace without downtime
- Save up to 70% compared to public cloud storage costs with standard hardware and zero ingress/egress fees
- Enjoy low latency and high bandwidth with local hardware
- Maintain strict control over data behind your own firewall
- Seamlessly integrate with cloud environments and S3-compatible apps

Hetzner Object Storage
Hetzner offers a strong European contender for object storage, boasting impressive price-to-performance that catches the eye immediately. While the service is relatively new on the scene - and early beta tests revealed some hiccups - their reputation suggests these kinks have been ironed out. It's a smart choice for those seeking solid storage without breaking the bank.
Storage costs at Hetzner sit comfortably at $0.00713 per gigabyte each month, which makes it a wallet-friendly option compared to many others. What really turns heads is their egress pricing: just $0.00143 per gigabyte. To put that in perspective, this is roughly 60 times cheaper than AWS egress fees. If you’re moving data in and out frequently, that saving adds up fast.
Of course, there are a couple of trade-offs. Hetzner’s data centers don’t span the globe like some competitors, so if you need truly global presence, this might be a sticking point. Also, their sign-up process is a bit like applying for a secret club membership - strict and cautious, designed to keep scammers and troublemakers at bay. So, patience and some paperwork might be part of your onboarding adventure.
