Co-founder of Signadot here. Computers and software programs become multi-tenant so they can do more and support concurrent users with fixed resources. However, when it comes to test environments for cloud native applications, most are single-tenant, meaning teams can't easily share a testing environment for different features.
The idea here is to bring multi-tenancy to test environments by routing traffic through specific versions of microservices. This way, multiple testing environments can be created at a lower cost, enabling new use cases that were too expensive before. This blog post is about one such use-case around end-to-end testing of a set of PRs realized in a cost effective way. Would love to get your feedback!
