Designing serverless functions for easy evolution

Cloud functions and serverless platforms force teams to make more granular components. If done right, this can be great for isolation, speeding up delivery, and simplifying operational tasks. If done wrong, this can make teams quickly lose the big picture and produce a spaghetti system of interconnected services that is very tricky to maintain.

Gojko will talk about the key design constraints and guidelines on how to split, organise and manage cloud functions for easy evolution.

The talk is based on two products that have been running serverless for a while now (www.MindMup.com since 2016, and www.Narakeet.com since 2019), evolving significantly over the years and benefitting greatly from good design.

You'll get some great actionable tips on how to structure code for easy development, maintenance, and testing, hear about some experiments that didn't work that well, and learn how to maintain a high speed of delivery with confidence:

- how to decide when to split code into multiple functions or keep it together

- how to coordinate multiple cloud functions effectively

- how to design code inside a single function for testability

- how to support multi-versioning but still ensure data integrity

- how to design for parallelisation but enforce synchronisation when needed

DynamoDB - Brief introduction to Single-Table Design

During the presentation, we will be designing a complete database for a blogging platform. By employing the principles of Single-Table Design, we will push the limited querying capabilities of DynamoDB to their limits. We will start by finding the entities and relations between them. Next, we will figure out the data access patterns that will be required to build the desired application. Finally, we will be shaping our data, so that it could all fit into a single DynamoDB table and would allow efficient querying and massive scalability.
