New Relic’s quick intro into serverless performance. Article presents a new challenge to operators and developers: how do you build fast and resilient functions when many traditional system and application metrics are either unavailable or no longer relevant?
Article reads about observing cold start time in the real world. Functions will vary in their execution time, yet all of these functions are identical and run in the same region. The only difference is how often they are triggered from an external API request.
Outcome: Warming the green function had no significant impact on how quickly the external request completed and the warmed Lambda function sometimes responded more slowly than the cold Lambda functions did.
Interesting read.
