Rainbow Smile Case Study: Success Story

Reducing TTM and Increasing Speed of Hypothesis Testing with a Gateway Solution

Location: Saint Petersburg, Russia Industry: E-Commerce, Retail

To us, KrakenD is an enterprise system that forgives mistakes and allows you to get the desired result.

The challenges

At “Rainbow Smile”, we faced challenges with publishing technical APIs from external sources, leading to increased development costs and a violation of the Domain Driven Design. We also needed help publishing the REST interface, which required developer involvement.

Scenario

To solve these challenges, we implemented KrakenD as a gateway for systems that do not support gRPC. In addition, we have moved the API configurations to appropriate repositories and included KrakenD in our current delivery cycle.

Results and Outcomes

We have seen a reduction in Time To Market for epics by 10% and a 100% decrease in crashes related to configuration consistency errors. It has also allowed for faster launch of API prototypes, with a 70% increase in speed for hypothesis testing.

The company plans to scale this experience to all public systems and bring part of the functionality (caching, authentication) to the responsibility of KrakenD.

Why KrakenD

“Rainbow Smile” chose KrakenD due to its low entry threshold, k8s-readiness, excellent documentation, performance, and reliability.

To us, KrakenD is an enterprise system that forgives mistakes and allows you to get the desired result.
