AWS Elasticsearch offers a managed service for ELK clusters, but its pricing model, which involves scaling costs either horizontally or vertically, can become expensive. Horizontal scaling, which adds more machines, increases costs linearly, while vertical scaling, which enhances existing resources, results in a steeper cost increase. A comparison with Coralogix's full ELK SaaS stack reveals that managing an ELK stack on AWS can cost around $20,000 annually, inclusive of setup, compute, storage, and maintenance costs. In contrast, Coralogix Streama provides a more cost-effective solution with optimized logging pipelines, significantly reducing costs by only processing crucial logs and leveraging machine learning for alerts and insights, with yearly costs ranging from $1,440 to $4,344, depending on storage size. This highlights the potential for cost savings and efficiency improvements in log management through Coralogix's platform.
