The following chart shows the typical range of cold starts in Google Cloud Functions, broken down per language. The darker ranges are the most common 67% of durations, and lighter ranges include 95%.

Google Cloud Functions have a setting to define the memory size that gets allocated to a single instance of a function. The CPU resources are allocated proportionally to the memory. So, in theory, larger instances could start faster.

The following chart shows the typical range of cold starts in Azure Functions, broken down per language. The darker ranges are the most common 67% of durations, and lighter ranges include 95%.

The following chart shows the typical range of cold starts in AWS Lambda, broken down per language. The darker ranges are the most common 67% of durations, and lighter ranges include 95%.

AWS Lambda has a setting to define the memory size that gets allocated to a single instance of a function. The CPU resources are allocated proportionally to the memory. So, in theory, larger instances could start faster.

AWS Lambda might need to access resources inside Amazon Virtual Private Cloud (Amazon VPC). In the past, configuring VPC access slowed down the cold starts significantly.

Azure Application Insights is an analytics service to monitor live web applications, diagnose performance issues, and understand what users actually do with the app. Aurelia is a modern and slick single-page application framework. Unfortunately, there’s not much guidance on the web about how to use AppInsights and Aurelia together in a proper manner. The task gets even more challenging in case you are using TypeScript and want to stay in type-safe land. This post will set you up and running in no time.
