Understanding the evolution of cloud compute models

Cloud computing has evolved from heavyweight virtual machines to middleweight containers and finally to lightweight serverless functions.

#3about 5 minutes

Identifying the key challenges of serverless functions

Traditional serverless platforms suffer from slow cold start times, dependencies on specific operating systems, and a complex developer experience.

#4about 6 minutes

Defining WebAssembly and its original design goals

WebAssembly was created as a secure, portable, and fast binary format for the web, designed to be a compilation target for many programming languages.

#5about 2 minutes

How technologies like Java and Ruby outgrew their purpose

Languages like Java and Ruby evolved far beyond their initial use cases, showing how a technology's application can expand over time.

#6about 3 minutes

Applying WebAssembly to solve serverless performance issues

WebAssembly's features like a strong security sandbox and sub-millisecond cold start times make it an ideal runtime for high-performance serverless functions.

#7about 2 minutes

Introducing Spin for building WebAssembly serverless applications

The open-source Spin tool simplifies building and deploying WebAssembly-based serverless functions with commands for scaffolding, building, and running applications.
