concurrency to improve I/O performance. • OpenStack & Kubernetes: openEuler is designed for cloud applications. It integrates the two mainstream pieces of cloud scheduling and management software to build Programming (ROP) attacks. 15. ILP32 support: The Kunpeng 920 ARM64 environment supports 32-bit applications. 16. Memory System Resource Partitioning and Monitoring (MPAM): Cache QoS and memory bandwidth status and resources. Application Scenarios Application scenario 1: kernel CVE fixes Typical applications, such as Nginx, Redis, and MySQL, run on a physical or virtual machine. They generate many keep-alive

compatible with multiple computing architectures. openEuler suits operational technology (OT) applications and enables the convergence of OT and information and communications technology (ICT). The scenarios. It has a rich history of helping enterprises develop their software, hardware, and applications. The openEuler open source community was officially established on December 31, 2019, with the KubeEdge+ edge-cloud synergy framework to provide unified management, provisioning of edge and cloud applications, and other capabilities. • Embedded: openEuler 21.09 Embedded is released for embedded scenarios
