3 ways to end the misery of tech migrations
Safely migrate and modernize across cloud services, databases, and APIs.
Customer success stories
The best migration stories are free of drama. Here are two examples of customers leveraging LaunchDarkly's safe, progressive migration capabilities to modernize their legacy applications without downtime for their customers.
Nestlé Purina's Petfinder migrates to microservices without disrupting service for pet seekers
Challenge
Petfinder is the largest online pet adoption site in North America. The site was acquired in 2013 by Nestlé Purina Petcare, a subsidiary of Nestlé S.A, a multinational food and drink processing corporation. Since then, Petfinder and Nestlé Purina Petcare have been on a mission to match people with their perfect pets, but Petfinder's legacy on-premises monolithic website hindered agility and created deployment risk. They needed to re-architect to microservices while maintaining business continuity.
Solution
With LaunchDarkly, Petfinder could gradually migrate their infrastructure piece by piece, while keeping their site up for pet seekers. LaunchDarkly enabled Petfinder to roll new front- and back-end features out to a subset of users, validate performance along the way, and instantly roll back if needed.

Result
- Migrated to modern architecture without downtime
- 2x increase in deployments

As we're continuing to modernize all of the technology that we're using, we're able to use LaunchDarkly on AWS to roll out new features in a safe way, to make sure that we don't take the site down … LaunchDarkly gives us the confidence to make these changes that make it more efficient, because we want to make sure that we can have the best experience for all of our users.

Hireology migrates seamlessly to Azure Cloud and slashes infrastructure hosting costs
Challenge
Hireology is an all-in-one hiring and HR platform founded in 2010. Hireology's development team was struggling to deliver successful, frequent releases, while also facing the challenge of a large-scale migration to Azure.
Solution
Hireology broke down their monolithic migration into components to reduce risk, migrating each individually to Azure. They then leveraged segmented user targeting to route user traffic between their legacy systems and public cloud. With this approach, they were able to revert instantly in the event of an error.
Results
- 8% change failure rate, down from 75%
- 14x increase in deployments and 65% increase in loading time speed
- Migrated legacy components to Azure Cloud seamlessly and with no negative impacts on customers
- Significantly reduced infrastructure hosting costs with LaunchDarkly
Additionally, by integrating LaunchDarkly with APM (Datadog), Hireology:
- Increased deployment frequency from 2x a month to on-demand
- Cut lead time from 14 days to 3 hours
- Slashed recovery time from a couple days to less than an hour
What LaunchDarkly does is it provides a safety net for this change so we can test out the Azure app services without exposing it to everybody in the world.
