What cloud providers are used by Stackhero?
We created our own cloud software solution, making us completely independent from cloud providers. We deploy this innovative solution directly on bare-metal servers, providing you with incredible performance and stability.
Where is the data hosted?
Stackhero is a French company operating under European and French laws.
Servers are located, depending on your choice, either in the European Union (France) or in the USA.
Backups are stored in the European Union.
What is the software infrastructure?
Your service is composed of multiple subservices. All of them are running in containers, within a virtual machine, totally dedicated to you.
This VM is totally private and isolated from other clients, offering a highly secured environment with very high-performance.
It is hosted on a bare-metal server running Stackhero DC OS, our own Linux distribution.
What about disk performance?
We use disks physically plugged to your instances.
We don't use network disks, contrary to traditional cloud solutions, that are slow and expensive.
This way we ensure best performances and exceptional IOPS.
What is the atomic backup system?
The problem with traditional backup systems is that files are saved at different times interval.
Let's say you have 2 files, a.txt and b.txt. Your backup starts at 9am and it finishes at 10am.
The file a.txt will contain data from 9am and b.txt will contain data from 10am.
This is traditional in backups systems and is a big issue leading to consistency problems.
This is why we developed an in-house backup system that takes an atomic image of your instance at a precise moment.
Atomic in a way that we can guarantee that all files from the backup have been taken exactly at the same time.
If your backup starts at 9am, all files will have data from 9am. You have a perfect consistent and reliable backup.
Are backups encrypted?
Backups are first transmitted to a dedicated server, which verifies and validates the data. Once these checks have been approved, the backups are encrypted and archived.
Encryption uses ECDH and Curve25519 as part of the OpenPGP protocol, with a unique key generated for each backup.
How does billing work?
At the beginning of each month, our system computes how many hours your services were up and a detailed invoice is created.
You receive a single monthly invoice, containing all your services, clearly explained and easy to understand. Your accounting department will love that!
What certifications does Stackhero hold?
The primary mission of Stackhero is to provide a platform that is easy to use, extremely reliable, and highly secure.
A key element in achieving this mission is the annual attainment of the ISO 27001 certification, a globally recognized quality and security label.
This certification, awarded following a rigorous audit conducted by an independent external body, attests to compliance with the strictest international standards in information security.
