Episode 103 — SMT and Oversubscription in Cloud Environments
In this episode, we define Simultaneous Multi-Threading (SMT) and how it allows a single CPU core to execute multiple threads concurrently, improving utilization and throughput. We also discuss oversubscription, where more virtual resources are allocated than physically available, leveraging the fact that not all workloads use their full allocation simultaneously. These techniques can improve efficiency but require careful planning to avoid resource contention.
We also highlight the risks of excessive oversubscription, which can cause performance degradation during peak demand. On the Cloud+ exam, SMT and oversubscription concepts often appear in performance optimization and capacity planning questions.
