SST features and specs

Ease of Use
SST is designed to simplify the process of building serverless applications, providing developers with higher-level abstractions and tools that streamline development.
Integration with AWS
SST is well-integrated with AWS services, allowing developers to leverage the full power of AWS infrastructure while maintaining a focus on serverless architecture.
Live Lambda Development
SST supports live Lambda development, enabling developers to make real-time changes and see them reflected immediately without the need for lengthy deployment processes.
Infrastructure as Code
With SST, developers can define their infrastructure programmatically, which promotes version control, scalability, and collaboration among team members.
Flexibility
SST provides flexibility to developers, allowing them to use popular libraries and frameworks alongside serverless components, thus accommodating various use cases.

Possible disadvantages of SST

Learning Curve
Developers unfamiliar with SST and its abstractions may face a learning curve in understanding how to effectively use the toolkit and take full advantage of its features.
AWS Lock-in
As SST is tightly integrated with AWS services, it can lead to vendor lock-in, making it challenging for organizations to switch to other cloud providers in the future.
Complexity for Small Projects
For smaller projects, the overhead introduced by SST's abstractions and tooling might be unnecessary, adding complexity without significant benefits.
Dependency on Community Support
SST relies on community support for maintenance and feature development, which could pose a risk if the community's interest wanes or if support does not keep pace with AWS innovations.
