Serverless Framework

The Serverless Framework is an open-source framework that simplifies the development and deployment of serverless applications across various cloud providers, primarily focusing on AWS.

Serverless Framework V.4 requires organizations with annual revenues exceeding $2 million to purchase a subscription license, while V.3 will continue to receive critical updates until the end of 2024. Developers have expressed dissatisfaction with these changes.

Focus

• Single YAML config file for managing app: Centralizes configuration in a single file, making it easier to manage application settings and resources.
• Connect managed services and code: Facilitates integration between serverless functions and various cloud services without extensive boilerplate code.
• Redeploy: Simplifies the redeployment process of applications with minimal downtime, allowing for quick updates and iterations.
• Scaling: Automatically adjusts resources based on demand, ensuring optimal performance and cost-efficiency without manual intervention.

Key Features

• Integrated CI/CD: Streamlined deployment processes integrated into the framework.
• Secrets: Enhanced management of sensitive information through secure storage options.
• Plugins: Offline Lambda emulator, API Gateway domain management, AWS Step Functions architectures, Python requirements, and more.
• Variable Resolver: Introduced in V.4, allowing integration with external services like Terraform and Vault for variable management.
• Extensions: New feature in V.4 enabling support for additional serverless vendors and use cases, with a revenue-sharing model for extension creators.
