Developers are increasingly adopting microservices to overcome the rigidity of traditional monolithic applications, with benefits such as separation of concerns, team autonomy, fault tolerance, and scalability across multiple regions for enhanced availability. However, microservices introduce infrastructure complexities, requiring more monitoring and management of services. Load balancing is crucial for distributing client requests across various application instances, enhancing performance, availability, and customer experience. Different load balancing algorithms, including DNS, round robin, and ring balancer, offer varied advantages and disadvantages, depending on the need for session consistency or the ability to quickly add or remove hosts. Health checks, both active and passive, are essential for detecting and responding to failed hosts, ensuring traffic is rerouted to maintain service availability. Circuit breakers further enhance fault tolerance by diverting traffic from unhealthy hosts, aiding in system recovery and supporting deployment strategies such as blue-green or canary deployments. Kong, a leading open-source API management platform, simplifies delivering high availability for microservices with features such as richer health checks, load balancing, and a user-friendly interface, offering both community and enterprise editions that cater to different operational needs.
