The Future of Serverless: Our Predictions for 2023

by Chelsea Hagon, Senior Developer

1. Lambda Observability

One of the key roadblocks to widespread adoption of AWS Lambda has been the lack of deep observability into system performance. Yet, with the introduction of AWS CloudWatch Lambda Insights and new third-party tools, developers are starting to gain a more profound understanding of their Lambda functions.

In 2023, we predict that improved techniques for logging, monitoring, and debugging Lambda functions will emerge, driven by the demands of increasingly complex serverless applications. Expect Lambda observability to no longer be a challenge but rather an integral part of serverless development workflows.

2. DynamoDB Dominance

DynamoDB's flexible NoSQL model has already made it a top choice for serverless web applications. However, its full potential has often been untapped due to the complexity of implementing single table designs.

As more resources and tutorials emerge demystifying single table designs, we predict that DynamoDB's dominance will continue to grow in 2023. Expect to see more sophisticated applications taking full advantage of DynamoDB's speed, scalability, and adaptability.

3. Serverless SQLite

SQLite's self-contained, serverless, zero-configuration approach aligns perfectly with the serverless paradigm. It provides a simple yet powerful solution for applications that don't require the scale provided by distributed database systems like DynamoDB.

In 2023, we expect to see more serverless environments embedding SQLite, allowing developers to benefit from its full-text search, geospatial indexing, and other advanced features while keeping the operational overhead minimal.

4. Server Side Rendering (SSR) to the Edge

SSR improves SEO and user experience by generating the full HTML for a page on the server in response to navigation. But when combined with edge computing, the benefits multiply.

In 2023, we anticipate seeing more SSR applications being deployed directly to the edge. This trend will reduce latency, increase performance, and provide an overall better user experience. As edge networks expand and become more capable, edge-based SSR will undoubtedly be a significant part of the web's future.
