Elastic has transitioned its Elasticsearch platform to a serverless architecture with the launch of Elastic Cloud Serverless, aiming to meet changing customer demands for simplified infrastructure management and pay-per-use models. This transformation involved shifting from a stateful to a stateless system by leveraging cloud-native object stores for persistent storage, adopting Kubernetes for orchestration, and employing a cell-based architecture for resilience. The platform also implements custom autoscaling controllers to optimize resource allocation and has developed a flexible pricing model aligned with actual usage. Elastic's approach includes using Crossplane for infrastructure management, addressing networking challenges with Cilium, and ensuring high availability through proactive capacity planning. The company emphasizes a cultural shift towards continuous innovation and automation, positioning Elastic Cloud Serverless as a scalable, efficient, and customer-centric solution for running Elasticsearch, with plans for ongoing feature development to enhance customer experience in the evolving serverless landscape.
