Oracle Solaris is great due to the fact that it actually is meant for high-end servers.
Oracle Solaris enables quick and secure deployment of new environments with virtualization features and is known for reliability, scalability, and stability. While it excels in database operations and resource partitioning, setup complexity and package management lag behind Linux. Despite valued ease of use, cost and integration issues persist, with room for improvement in scalability, SVM enhancements, and customer service. Incremental backups and zone manipulation offer flexibility, yet memory use inconsistencies and version updates pose challenges.
