Serverless is a cloud computing model where applications are hosted on a cloud platform without the need for a dedicated server or virtual machine. Instead, cloud resources are allocated and released dynamically depending on the demand of the application. This allows developers to focus more on the development of the application instead of maintaining the underlying infrastructure. Serverless computing is also cost-effective because it only charges for the exact amount of resources used, rather than paying for an idle server.

Advanced GraphQL Architectures: Serverless Event Sourcing and CQRS
Watch video: Advanced GraphQL Architectures: Serverless Event Sourcing and CQRS
GraphQL is a strongly typed, version-free query language that allows you to ask for specific data and get it in JSON format. It simplifies data retrieval and modification by allowing the server to handle all necessary operations. Serverless architectures, such as AWS Lambda, are scalable, cost-effective, and good for event-driven applications. Event sourcing and CQRS are techniques that ensure consistency and separate reading and writing parts of an application. Building a GraphQL API with commands and queries can be achieved using AWS AppSync and DynamoDB. This approach offers low latency, scalability, and supports multiple languages. Challenges include application complexity, data modeling, and tracing, but starting with simplicity and making something work first can lead to success.

Serverless for Frontends
Welcome to my session on Serverless for Front-ends. Serverless functions eliminate the need for a runtime and handle orchestration for you. Microfrontends require a runtime and orchestration, but side-less UIs provide a runtime-free solution. In the demo, a new team adds functionality to an application and publishes it easily. Building and deploying applications is quick and easy with micro apps and PowerCLI, offering true loose coupling and instant availability without a runtime.

This workshop discusses the challenges Enterprises are facing when scaling the data tier to support multi-region deployments and serverless environments. Serverless edge functions and lightweight container orchestration enables applications and business logic to be easily deployed globally, often leaving the database as the latency and scaling bottleneck.
Join us to understand how PolyScale.ai solves these scaling challenges intelligently caching database data at the edge, without sacrificing transactionality or consistency. Get hands on with PolyScale for implementation, query observability and global latency testing with edge functions.

Building a Serverless GraphQL API in 7 Minutes
Maxime Beunier, a developer advocate at MongoDB, demonstrates how to build a serverless GraphQL API using MongoDB Atlas and Realm. He creates a new app called Galaxy, links it to the production cluster, and deploys it in Ireland. He then shows how to authenticate users and obtain a token to access the GraphQL API. The demo showcases the ease and speed of building a serverless GraphQL API and provides all the necessary links for further exploration.

From 1 to 101 Lambda Functions in Production: Evolving a Serverless Architecture
Vacation Tracker is a serverless startup using Node.js that started with a simple lambda function and now has many lambda functions. They built a system connected to Slack and calendars, which is now used by many startups, companies, and organizations. They evolved to an event-driven architecture using CQRS and AWS AppSync with Managed GraphQL. Onboarding new developers is a challenge, but serverless allows them to assign a new environment and AWS account to each developer. Testing and monitoring are crucial, and they have successfully migrated from MongoDB to DynamoDB.

Writing Testable Serverless Apps Using Hexagonal Architecture
The scariest thing about serverless is the fear of vendor lock-in and losing control. Planning, good architecture, and deployment procedures help keep switching costs reasonable. Hexagonal architecture is a useful approach for writing testable serverless apps. Integration testing is crucial for serverless apps, and hexagonal architecture helps fight vendor lock-in and reduce switching costs. Docker is used for testing serverless functions, and the practicality of hexagonal architecture remains a question.
