System and application performance remains a primary goal in enterprise and cloud computing. Each new Red Hat Enterprise Linux release brings higher performance, improved toolsets, and advanced tuning and analysis techniques. Performance engineers must constantly meet functional and business requirements in IT systems: to increase workload volume, reduce system bottlenecks and failures, with a final goal of increased business revenue and customer satisfaction. This course provides the skills needed to customize a solution for performance efficiency issues and allow for future scalability.
Performance tuning and capacity planning for Red Hat Enterprise Linux
Red Hat Performance Tuning: Linux in Physical, Virtual, and Cloud (RH422) teaches senior Linux® system administrators the methodology of performance tuning. This course discusses system architecture with an emphasis on understanding its implications on system performance, performance adjustments, open source benchmarking utilities, networking performance, and tuning configurations for specific server use cases and workloads.
This course is based on Red Hat® Enterprise Linux 8.
Senior Linux system administrators responsible for maximizing resource utilization through performance tuning
