Case Study: Nylas achieves 30x account synchronization performance with Speedscale

Nylas improves account synchronization performance 30x with Speedscale

Nylas, a fast-growing SaaS technology vendor, faced challenges ensuring uptime and stability while migrating from an EC2 monolith to Kubernetes. They needed a solution to handle increased integration loads from larger customers and to benchmark APIs effectively in their new, complex microservices environment. After evaluating options, they chose to implement Speedscale's traffic replay platform to maintain performance parity during their migration.

Using Speedscale, Nylas was able to observe API traffic, generate mocks of critical third-party dependencies like Office365 and Google Apps, and replay traffic at scale. This allowed them to rapidly iterate and validate new service versions at production volumes. The solution enabled a 30x improvement in account synchronization performance within a few months, helping Nylas meet heightened customer expectations in a short timeframe.
