Serverless and Related Platforms ☁️

🚀 What is Serverless?

Serverless is a cloud computing model where service providers fully manage the infrastructure, allowing developers to focus solely on writing code. The system automatically allocates resources based on demand and charges only for actual resource usage. Serverless architecture is commonly applied for microservices applications, event processing and helps minimize operational costs.
