+# What is Serverless Compute?
+
+Serverless computing is a cloud computing model where the cloud providers manages the infrastructure and dynamically alocates computing resources as needed.
+
+This means that you don't have to provision machines, manage a cluster or pay for servers. Your application code is executed on demand and you only pay for the compute time consumed by your software.
+
+This approach enables greater scalability, flexibility and cost-effectiveness.
+
+Key features:
+* **Automatic scaling:** your application can scale up or down automatically based on demand
+* **No server management:** you don't need to provision, maintain or manage servers
+* **Pay as ou go:** you only pay for the compute time you consume, making it cost effective
+
+Serverless is not limited to Serverless Function which is perfect to deploy small chunks of code, it can also directly deploy containers on Serverless Containers and Serverless Jobs.
+
+# Why Serverless?
+
+Serverless offers numerous advantages that can significantly enhance your development and operational efficiency:
+
+* **Cost savings:** You only pay for the compute time your code uses, which can lead to significant cost reductions. No idle resources.
+* **Scalability:** Automatically scale your applications to handle varying loads without manual intervention. It's perfect for seasonal traffic and viral apps.
+* **Faster time to market:** Focus on writing code rather than managing infrastructure, accelerating your development cycles.
+* **Reduced operational overhead:** Let the cloud provider handle server maintenance, updates, and scaling, freeing up your team to focus on innovation.
+* **Eco friendly:**  Optimized resource usage reduces wasted energy.
+
+
+# How to control costs of Serverless?
+
+Serverless is inherently cost-transparent, tips to otpimize costs:
+* Use efficient code and set timeouts
+* Monitor usage with built-in observability
+* Define a max-scale setting
+
+Remember: Serverless eliminates upfront capital expenses and reduces operational costs giving you predictable, granular billing.
+
+# Ready to go Serverless?
+
+By adopting Serverless, you are choosing agility, innovation, and cost savings.
+Whether you are a startup scaling rapidly or an enterprise modernizing legacy systems, Serverless lets you focus on what matters: delivering value to your users.
+
+You can fully deploy your API on Serverless or use it to emporer and add automation to your infrastructure.
+Serverless is excellent at handling traffic spikes, useful to offload regular servers on special events.
+
+# Is my applicaiton a good fit for Serverless?
+Most applications can benefit from Serverless! Here's when it shines:
+
+* Event driven workloads: file processing, real time notification, IoT data streams.
+* Microservies and APIs: Stateless, short-lived tasks (e.g., user authentication, payment processing, etc...)
+* Sporadic traffic: Aps with variable usage (e.g., marketing campaigns, ticketing system).
+* Rapid prototyping: Test ideas quickly without upfront infrastructure investment
+
+# How secure are Serverless resources?
+
+**Isolation:** Each container runs in a secure, isolated environment
+**IAM integration:** Fine-grained access control via IAM, inject directly required redentials to Serverless ressources.
+
+# How do I debug and monitor applications in a Serverless environment?
+
+Scaleway provides full observability:
+
+* **Logs and metrics:** Centralized logging and real-time metrics via Cockpit
+* **Local debugging:** Test containers locally using the Serverless CLI and emulator
+* **Error Reporting:** Automatic alerts for failed invocations or resource bottlenecks via Cockpit
+
+# Will Serverless lock me into the ecosystem?
+No. Scaleway Serverless is designed to minimize vendor lock-in.
+We believe in empowering your freedom to choose, adapt, and evolve. Here is how we ensure flexibility:
+
+## Container portability
+- **Docker compatibility**: Your container images (built with Docker, Helm, or other tools) are portable. You can redeploy them elsewhere—on-premises, on other clouds, or in hybrid environments.
+- **No proprietary formats**: We don't modify your containers. What you build works anywhere.
+
+## No proprietary lock-in
+- **No forced dependencies**
+- **Open APIs**: Manage Serverless Containers via REST APIs, Terraform, CLI, etc... no proprietary control required.
