提供的 RabbitMQ 版本是什麼？
Stackhero 致力於始終提供最新且穩定的 RabbitMQ 版本，確保您能夠使用 RabbitMQ 實例的最新功能和全部功能。
每秒可以處理多少訊息？
每秒發送的訊息數量沒有限制。這些訊息的速率取決於您的訊息大小、路由類型以及您擁有的消費者/生產者數量，並且可能因每個使用案例而異。
通訊是否使用 TLS/SSL 加密？
通訊使用 TLS/SSL 加密，我們支援現代加密算法，例如 TLS 1.2 版本，以及為了達到最高安全性，支援最新的 TLS 1.3 版本。我們使用 RSA 2048 位元證書和 ECDSA 來提升相容客戶端的通訊速度。要使用加密連接，只需在連接到 RabbitMQ 時將 amqp:// 替換為 amqps://。
有包含任何插件嗎？
是的！您可以在 RabbitMQ 設定面板中簡單地一鍵啟用它們。
我們目前支援 Delayed Message Exchange、Message Deduplication、Federation、Event Exchange、Shovel、Consistent-hash Exchange、HTTP backend authentication 和 Prometheus 插件，並計劃添加其他插件。如有需要，歡迎隨時聯絡我們討論您的需求！
HTTP API 是否可存取？
是的，您可以在服務 URL 後加上 /api 來訪問 RabbitMQ HTTP API。
是否可以使用SSH連接到該實例？
由於 Stackhero 提供託管服務，因此不提供 SSH 訪問。如有任何安裝需求，請聯絡支援以探索可能的解決方案。
Is it possible to restrict access based on IPs with a firewall?
Absolutely! Your instance has its own firewall where you can decide which IPs have access to which port in 2 clicks.
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.
