FAQ about Stackhero for Graylog cloud

We include OpenSearch, MongoDB, an email server (unlimited!) as well as a reverse proxy.
You don't need to add any other services, Graylog is ready to be used directly.

Unlike traditional cloud providers, Stackhero allows unlimited concurrent connections!
The power of your instance is entirely dedicated to you. You can use as many connections as you want as long as your instance can handle them.

We have included official plugins from the Community Edition as well as the Slack/Mattermost and Telegram Alert plugins.
If needed, we can potentially add other plugins. You can contact us, and we will review your request.

You can keep your logs as long as you want.
As long as the disk space of your instance supports it, there is no limit!

You can configure the retention of your logs with great precision using the Graylog interface.
For example, you can choose to keep the logs for the last 365 days, retain the last 200 million messages, or limit the occupied space to 400GB.

Graylog uses a journal that acts as a buffer between the time it receives the logs and when they are stored in the OpenSearch database.
This journal can occupy up to 7GB of disk space on your instance.

Additionally, Graylog, MongoDB, and OpenSearch require disk space to function properly.
Since OpenSearch has a protection mechanism, the database will automatically switch to read-only if the disk has less than 7GB of free space.

This is why we advise you to configure your retention to always have 15GB of free disk space on your instance to ensure its proper functioning.

Since Stackhero provides managed services, SSH access is not available. For any installation needs, please contact support to explore possible solutions.

Absolutely! Your instance has its own firewall where you can decide which IPs have access to which port in just 2 clicks.

We developed our own cloud software solution, making us entirely independent from cloud providers. We deploy this innovative solution directly on bare-metal servers, offering you exceptional performance and stability.

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.

Your service consists of multiple subservices. All of them run in containers within a virtual machine that is entirely dedicated to you.
This VM is completely private and isolated from other clients, providing a highly secure environment with very high performance.
It is hosted on a bare-metal server running Stackhero DC OS, our own Linux distribution.

We use disks that are physically connected to your instances.
We don't use network disks, unlike traditional cloud solutions, which are slow and costly.
This way, we ensure optimal performance and exceptional IOPS.

The issue with traditional backup systems is that files are saved at different time intervals.
Let's say you have 2 files, a.txt and b.txt. Your backup starts at 9 a.m. and finishes at 10 a.m.
The file a.txt will contain data from 9 a.m. and b.txt will contain data from 10 a.m.
This is common in backup systems and leads to significant consistency issues.

This is why we developed an in-house backup system that captures an atomic image of your instance at a precise moment.
Atomic in the sense that we can guarantee all files in the backup are captured at exactly the same time.
If your backup starts at 9 a.m., all files will have data from 9 a.m. You have a perfectly consistent and reliable backup.

Backups are initially sent to a dedicated server, which verifies and validates the data. Once these checks are 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.

At the start of each month, our system calculates the number of hours your services were operational, and a detailed invoice is generated.
You receive a single monthly invoice that consolidates all your services, clearly explained and easy to understand. Your accounting department will love it!

Stackhero's primary mission 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.
