Lessons learned from scaling to 1 million Lambda functions
In this post, we share our journey and the lessons learned from building and running a fully serverless, multi-account software as a service (SaaS) platform at scale. We’ll explore why true scale-to-zero is critical, how we handle quota management, why engaging AWS service teams early saved us from outages, and which unexpected practices emerged once we scaled from thousands to over a million functions.
6,000 AWS accounts, three people, one platform: Lessons learned
This post describes why ProGlove chose a account-per-tenant approach for our serverless SaaS architecture and how it changes the operational model. It covers the challenges you need to anticipate around automation, observability and cost. We will also discuss how the approach can affect other operational models in different environments like an enterprise context.
