Netflix is renowned for its dedication to innovation and customer satisfaction. In pursuit of these goals, the company embarked on a journey to upgrade its applications to Spring Boot 3. This move aimed to establish a fresh baseline for future inventions, decrease complexity, reduce tech debt, reduce application start time, increase developer productivity, save money, and leverage a supported version of the framework with vulnerability patching. The early results of this endeavor are impressive, with a 15 percent voluntary adoption rate, significant cost savings, and streamlined operations.
Here are six key takeaways from Netflix Senior Software Engineer Asi Bross’s talk sharing details of this initiative at SpringOne 2023.
Starting early is critical
Netflix’s journey to Spring Boot 3 began in June 2022 and continues today, reflecting the importance of starting early to address the challenges associated with such a significant upgrade. The proactive approach allowed Netflix to plan meticulously and ensure a smooth transition.
Make it an organizational priority
Netflix deemed upgrading to Spring Boot 3 and Java 17 a top priority and expanded the effort to include the entire platform engineering team of five to work on the project.
Automate tools to minimize user intervention
Automation plays a pivotal role in Netflix’s success. By automating as much of the upgrade process as possible, the company has reduced the need for manual intervention, resulting in quicker adoption and reduced risk.
Serving a diverse application landscape
Netflix’s portfolio consisted of 3,000 applications and 1,500 libraries. Despite this complexity, the company successfully upgraded to Spring Boot 3, underscoring the adaptability and scalability of the Spring Framework.
Realizing significant cost savings
Netflix reports that it has already seen cost savings amounting to hundreds of thousands—possibly millions—of dollars thanks to the reduction in batch job boot-up times, according to Bross. This demonstrates the practical value of Spring Boot 3 in optimizing resource utilization.
Improve security with vulnerability patching
By upgrading to Spring Boot 3, Netflix is strengthening its ability to support and patch vulnerabilities promptly. This enhances security and aligns with best practices in software maintenance.
