SB Payment Service (SBPS) has reached its fifth year of using VMware Tanzu Platform for Cloud Foundry and is currently hosting one of the largest payment agency services in Japan. With only 20 developers and five operators, SBPS is delivering a transaction volume of 8 trillion yen with no downtime, demonstrating the power of Tanzu Platform for Cloud Foundry in scaling a development environment to massive levels. SBPS is now expanding its use of Tanzu Platform to refactor legacy applications and host them on the platform. In this session, you'll learn from SBPS's experience, and gain insights into how Tanzu Platform for Cloud Foundry can help you achieve similar results in your organization. We will explore how SBPS has applied new and proven technologies to modernize legacy applications and has overcome the challenges they faced along the way.
