Get to know the client & their business challenges!

Rent-A-Center is the leading American company helps its customers with rent-to-own service for key items like furniture, appliances, and electronics. They have implemented a leasing application to serve their customers with rent-to-own service for both online/offline stores.

Client team wanted to modernize their leasing application from on-premises infrastructure to cloud platforms. They could not scale at a faster pace with flexible data load in legacy data platforms.

With the on-prem application infrastructure, they could not plan frequent deployments or upgrades as there was third-party vendor intervention.

So, they were in search of a dynamic environment that can auto-scale with fluctuating user traffic.
