Alibaba Cloud launched the Eigen+ cluster manager, enhancing efficiency in database management through advanced memory oversubscription techniques. The approach addresses the common practice of allocating more memory to virtual machines than physically available, which aids in managing more guest machines on each host. However, this method carries risks, including Out of Memory errors, which may impact service availability. By combining historical memory usage data with bin packing algorithms, Alibaba Cloud seeks to minimize forecast errors, particularly in high-utilization scenarios, thus improving overall resource allocation and performance.
Alibaba Cloud has developed a new cluster manager called Eigen+ that improves database efficiency over previous hyperscale technologies by implementing advanced memory over-subscription techniques.
The Eigen+ system employs a blend of historical memory usage data and optimized bin packing algorithms to manage memory more effectively, reducing risks of Out of Memory errors.
Despite concerns over memory oversubscription, which can lead to Out of Memory errors, Alibaba Cloud's Eigen+ aims to enhance resource allocation in high-utilization environments.
The performance enhancements brought by Eigen+ indicate a significant advancement in addressing shortcomings of earlier memory management strategies in cloud computing environments.
