Serverless computing (Serverless) is a cloud computing execution model where the provider provides the customer with a ready—made programming environment, with server resources increasing or decreasing depending on the load. This way developers can focus on their core product and not waste time maintaining the infrastructure.
Advantages of the serverless model
Reduced operating costs. Serverless computing allows you to pay for the exact amount of resources that a company uses.
Scalability. Serverless architectures are designed to scale automatically, processing from a few requests to thousands per second.
High performance. Delegating tasks to a provider allows IT professionals to focus on their core services and innovations.
Quick entry into the market. Companies can deploy applications faster and more often, thereby reducing the time to market for products.
Serverless Application Areas
Microservices. Serverless computing is suitable for microservices architecture because it allows each service to scale independently.
Real-time file processing. You can run serverless functions whenever new files are uploaded to the cloud storage.
Data transformation. Serverless can be used to convert data to a more convenient format before storing it in a database.
