FAQ about Stackhero for Nextcloud cloud

Stackhero strives to always provide a recent and stable version of Nextcloud, ensuring access to the latest features and full capabilities of your Nextcloud instance.

Unlike traditional cloud providers, Stackhero doesn't charge per user!
The power of your instance is entirely dedicated to you, so you can add as many users as you want as long as your instance can handle them.

Collabora requires a separate server from Nextcloud. This configuration is not yet supported, so it is not possible to use Collabora Office with Stackhero for Nextcloud.

No, and that is exactly the value Stackhero brings. There are no servers for you to manage: Stackhero takes care of the operating system, security patches, service configuration, TLS certificates, firewall, monitoring, and daily atomic backups.
Everything you would normally do over SSH is available as a supervised action in your dashboard, with just one click: change the configuration, upgrade to a new version, resize the instance, open or close a port, or restore a backup.
You retain full access to the service itself, its admin console, APIs, and your data. Nothing related to your application is out of your reach.
This also reduces your attack surface: there are no SSH keys to rotate, leak, or brute-force.
If there is an option missing in the dashboard, let us know. That’s how the configuration page evolves on the platform.

No. That’s the whole point of Stackhero: you get a production-ready Nextcloud without needing to hire anyone to run it. No provisioning, no operating system to patch, no backup scripts to write or test, no monitoring stack to set up, no on-call rotation to manage.
Your team can focus on what makes your product unique, and all the infrastructure work that used to take weeks simply disappears.

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

Premium support is included with every plan at no additional cost. There is no support tier to purchase and no extra charge for priority support. Support is available by email and online chat during business hours, from 9 a.m. to 6 p.m. Central European Time. Typically, you will receive a first response within the hour.

Outside of these hours, your services continue to be monitored. Stackhero keeps an eye on them 24/7. If downtime is detected, automated remediation is triggered right away, and an on-call engineer is notified if the issue is not resolved. You do not need to be the first to notice an incident. You also do not need to manage your own on-call rotation.

Everything is included. The price you see on the pricing page is the total you pay: the service itself, the dedicated and isolated infrastructure it runs on, unlimited and unmetered network traffic, daily atomic backups and their storage, free and unlimited backup restores, updates and version upgrades, TLS certificates, your custom domain, firewall, monitoring, and premium support.
There are no setup fees, no per-user or per-seat charges, no support add-ons, no traffic bills, and no fees for restoring a backup.

At the start of each month, our system calculates how many hours your services were running and generates a detailed invoice.
You receive a single monthly invoice that includes all your services, presented clearly and easy to understand. Your accounting team will appreciate that!
There is no commitment: you can stop billing for a service with a single click, and you are only charged for the hours it was active.

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 data is automatically backed up at least once a day for every service and every plan. Additional backups are also performed automatically during sensitive operations such as updates or upgrades.
Retention: one backup per day is kept for 7 days, one per week for 1 month, and one per month for 3 months.
Each backup is stored in a vault located at least 200 km from the datacentre hosting your service, so a physical incident cannot affect both sites at the same time.
You can restore your backups at any time, as often as needed, with a single click. There are no restoration fees and no limits on the number of restores.

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.

Your service consists of several subservices, each running in containers within an environment dedicated entirely to you.
This environment is private and isolated from other customers, ensuring strong security and optimal performance.
Everything is hosted on a bare-metal server running Stackhero DC OS, our own Linux distribution, with disks physically attached to your instance to provide maximum IOPS.

This isolation is guaranteed by a dedicated virtual machine for each customer, not by shared containers on a multi-tenant host.

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.

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 founded in 2009. The platform itself launched in 2018, after two years of development, and has been running production workloads ever since.
The company is profitable and independent, with no outside investors and no exit planned. This stability is important when you choose a provider to host a service that is not easy to move. Stackhero is built to be here for the next ten years.

Both use the same platform. A startup can launch its first Nextcloud in production in two minutes on the smallest plan, then scale up to dozens of vCPUs as the product grows, without changing providers or migrating anything.
Larger organizations get the features they need (included for all companies on all plans): ISO 27001 certification, a GDPR-compliant Data Processing Agreement, a contractual 99.9% SLA, dedicated and isolated infrastructure, and a single monthly invoice that's easy for accounting to process.
In both cases, you only need to adjust the size of the instance.

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.
