Cloudburst: Stateful Functions-as-a-Service with Vikram Sreekanti

Serverless computing is a way of designing applications that do not directly address or deploy application code to servers. Serverless applications are composed of stateless functions-as-a-service and stateful data storage systems such as Redis or DynamoDB. 

Serverless applications allow for scaling up and down the entire architecture, because each component is naturally scalable. And this pattern can be used to create a wide variety of applications. The functions-as-a-service can handle the compute logic, and the data storage systems can handle the storage. But these applications do not give the developer as much flexibility as an ideal serverless system might. The developer would need to use cloud-specific state management systems.

Vikram Sreekanti is the creator of Cloudburst, a system for stateful functions as a service. Cloudburst is architected as a set of VMs that can execute functions-as-a-service that are scheduled onto them. Each VM can utilize a local cache, as well as an autoscaling key-value store called Anna which is accessible to the Cloudburst runtime components. Vikram joins the show to talk about serverless computing and his efforts to build stateful serverless functionality.

ExtraHop is a modern security company that provides complete visibility into your infrastructure. ExtraHop lets you detect threats and respond quickly, giving you the deep context you need, as well as the ability to set up automated response workflows. At, you can see a demo for how ExtraHop works.

It’s hard to get engineering resources to build back-office apps, and even harder to get engineers excited about maintaining them. The idea is that all internal tools kinda look the same – they’re made of tables, dropdowns, buttons, text inputs, etc. Retool gives you a drag and drop interface so engineers can build these internal UIs in hours, not days, and spend more time building features customers will see.
