The State of Serverless

The AWS Lambda release in 2014 pushed serverless into the mainstream. Other major cloud providers (Google, Microsoft, IBM) have caught up, and today there’s a vast offering of serverless services available. Not to mention the handful of feature rich, open source projects that enable running serverless applications on-premise. This talk will help you understand what serverless is, and how it improves software development and operations. It will provide an overview of the serverless ecosystem – from Function-as-a-Service providers to microservices orchestrators that allow building a complex state machine in the cloud. Without worrying about scalability, capacity planning, and security patches.
