+## What is serverless computing and how does it differ from traditional cloud hosting?
+
+Serverless computing is a cloud execution model where the cloud provider dynamically manages the allocation of compute resources. Unlike traditional hosting models, you don’t need to provision, scale, or maintain servers. Instead, you focus solely on writing and deploying your code, and the infrastructure scales automatically to meet demand.
+
+## Why consider using Serverless Containers, Functions or Jobs for my projects?
+
+These services allow you to build highly scalable, event-driven, and pay-as-you-go solutions. Serverless Containers and Functions help you create applications and microservices without worrying about server management, while Serverless Jobs let you run large-scale, parallel batch processing tasks efficiently. This can lead to faster development cycles, reduced operational overhead, and cost savings.
+
+## Can I run any application on Serverless Containers?
+
+Yes. Because Serverless Containers supports any containerized application, you can choose the language, runtime, and framework that best suits your needs. As long as it can run in a container and respond to HTTP requests, Serverless Containers can host it.
+
+## What are the cost benefits of using serverless services like Serverless Containers?
+
+With serverless, you only pay for the compute resources you actually use. There are no upfront provisioning costs or paying for idle capacity. When your application traffic is low, the cost scales down, and when traffic spikes, the platform automatically scales up, ensuring you never overpay for unused resources.
+
+## Does updates of Serverless Containers can cause downtime?
+
+No, when deploying a new version of your Serverless Container generates a **rolling update**. This means that a new version of the service is gradually
+rolled out to your users without downtime. Here is how it works:
+
+* When a new version of your container is deployed, the platform automatically starts routing traffic to the new version incrementally, while still serving requests from the old version until the new one is fully deployed.
+* Once the new version is successfully running, we gradually shifts all traffic to it, ensuring zero downtime.
+* The old version is decommissioned once the new version is fully serving traffic.
+
+This process ensures a seamless update experience, minimizing disruption to users during deployments. If needed, you can also manage traffic splitting between versions during the update process, allowing you to test new versions with a subset of traffic before fully migrating to it.
+
+## Can I update Serverless Container ressources (vCPU and RAM) at any time?
+
+Yes, Serverless Containers ressources can be changed at any time without causing downtime, see previous question.
+
+## How does scaling work in these serverless services?
+
+Scaling in Serverless Containers and Serverless Functions is handled automatically by the platform. When demand increases—more requests or events—the platform spins up additional instances to handle the load. When demand decreases, instances spin down. This ensures optimal performance without manual intervention.
+
+## How do I integrate my serverless solutions with other Scaleway services?
+
+Integration is straightforward. Serverless Functions and Containers can be triggered by events from Queues, SQS and SNS and can easily communicate with services like Managed databases or Serverless databases. Serverless Jobs can pull data from Object Storage or output processed results into a database. With managed connectors, APIs, and built-in integrations, linking to the broader Scaleway ecosystem is seamless.
+
+## Can I migrate existing applications to Serverless Containers?
+
+Yes. Many traditional applications can be containerized and deployed to Serverless Containers. This makes it easier to modernize legacy systems without a complete rewrite. By moving to a serverless platform, you gain automatic scaling, reduced operational overhead, and a simpler infrastructure management experience.
+
 ## Are applications deployed on Serverless Containers stateless?
 
 Yes, all applications deployed on Serverless Containers are stateless. This means the server does not store any state about the client session. Instead, the session data is stored on the client and passed to the server as needed.

 ## Why does my container have an instance running after deployment, even with min-scale 0?
 
 Currently, a new container instance will always start after each deployment, even if there is no traffic and the minimum
