Automatic scaling happens when a certain threshold is reached, such as CPU usage, that is captured by a monitoring mechanism and then triggers a change using orchestration capabilities.
Monitoring and Metering Monitoring and alerting tools focus on monitoring the usage of resources by both customers, and service providers, and provide alerts to optimize and manage workloads. It also helps to predict future requirements. To monitor PaaS development environment utilization, response, and event, the application tool that is best suited should be considered during designing. The effectiveness of a metering solution relies on the visibility into how cloud resources are used. You may have to consider a single metering and billing solution when services are deployed in a private or public cloud. You have to use a unified metering solution, if deployed across multiple clouds. Example: Amazon Cloud Watch: It collects and track metrics, monitors logfiles, set alarms, and automatically reacts to changes of AWS resources.
