Monolith to Event-Driven Microservices: 5 Tips for Securing Business Buy-In

In February 2021, McAfee embarked on a replatforming strategy to transition from a monolithic architecture to a cloud-native event-driven microservices architecture, aiming to enhance scalability, fault isolation, and time to market while reducing costs. This strategic shift was driven by the need to overcome the limitations of their existing infrastructure, which impeded their ability to rapidly innovate and protect over 500 million users from cyber threats. By adopting microservices, McAfee sought to improve business velocity and system availability, emphasizing the importance of decoupling services to ensure resilience and real-time responsiveness to security events. The transition process involved several phases, including modernizing the technology stack, leveraging managed services like Confluent Cloud for efficient event management, and emphasizing the importance of securing organizational buy-in by demonstrating immediate business benefits. This transformation not only enhanced McAfee's operational efficiency but also shifted their focus from device-centric to user-centric protection, aligning their architecture with contemporary technological standards to support future growth and innovation.
