SERVERLESS COMPUTING
Serverless computing is a cloud computing execution model where cloud providers dynamically manage the allocation and provisioning of resources. In a serverless environment, developers write and deploy code without worrying about the underlying infrastructure. The cloud provider takes care of scaling, server maintenance, and resource management, allowing developers to focus solely on writing code for their applications.
Key features of serverless computing include:
1. Event-Driven: Serverless functions are triggered by specific events, such as HTTP requests, database updates, or file uploads. The functions execute in response to these events and automatically scale up or down based on demand.
2. Pay-as-you-go: With serverless, you only pay for the actual execution time of your functions, rather than paying for idle server time. This cost-effective pricing model can lead to significant savings, especially for applications with sporadic or unpredictable workloads.
3. Scalability: Serverless platforms automatically handle the scaling of resources to accommodate changes in traffic and demand. This ensures that applications can handle sudden spikes in usage without manual intervention.
4. Low Maintenance: As the cloud provider manages the infrastructure, developers can focus more on writing code and less on infrastructure management, resulting in reduced operational overhead.
Serverless computing is commonly used for web applications, data processing tasks, IoT applications, and microservices architecture.
