Kubeless is an open-source serverless framework that runs natively on Kubernetes, allowing you to deploy and manage functions without worrying about the underlying infrastructure. It leverages the power of Kubernetes to provide auto-scaling, high availability, and efficient resource utilization for your serverless workloads.

• **Function-as-a-Service (FaaS):** Kubeless enables you to deploy and execute functions triggered by events or HTTP requests, abstracting away the complexities of infrastructure management.
• **Language Agnostic:** Kubeless supports a wide variety of programming languages, including Node.js, Python, Go, Ruby, and more, offering flexibility in choosing the best fit for your function requirements.
• **Custom Runtimes:** You can create and use custom runtimes to support additional languages or specific environments.
• **Event Triggers:** Kubeless integrates with various event sources, such as Kafka, NATS, and HTTP events, enabling event-driven function execution.
• **HTTP Triggers:** Functions can be exposed as HTTP endpoints, allowing them to be invoked directly through HTTP requests.
• **Autoscaling:** Kubeless leverages Kubernetes' Horizontal Pod Autoscaler (HPA) to automatically scale functions up or down based on demand, ensuring optimal performance and resource utilization.

• **Focus on Code:** Kubeless empowers developers to concentrate on writing their function logic without having to worry about setting up and managing servers.
• **Cost Efficiency:** The serverless model of Kubeless can lead to cost savings by only paying for the resources consumed when functions are executed.
• **Scalability:** Kubeless automatically scales functions to handle fluctuating workloads, ensuring optimal performance and resource utilization.
• **Language Flexibility:** The support for multiple programming languages and custom runtimes offers flexibility in choosing the best fit for your specific function requirements.
• **Kubernetes-Native:** Kubeless operates natively within Kubernetes, leveraging its APIs and resources for seamless integration and management.

While Kubeless relies on Kubernetes manifests and function code, here's a conceptual example of a simple Python function deployed with Kubeless:

```python

1. handler.py

def hello(event, context):

   name = event.get('name', 'World')
   return f'Hello, {name}!'

You would then package this function into a Docker image and deploy it to your Kubeless cluster using the `kubeless` CLI:

```bash kubeless function deploy hello-world –runtime python3.9 \

   --from-file handler.py --handler handler.hello
