- Problem solved
- The core problem solved was the manual, expensive, and complex process of distributing network traffic and ensuring application availability and scalability. Before cloud services, organizations relied on physical hardware load balancers that required significant upfront investment, extensive configuration, manual scaling, and dedicated operational teams to maintain high availability and cope with fluctuating demand. Cloud load balancers automated these tasks, making distributed application architectures accessible and cost-effective for a wider range of businesses.
