In hybrid workload model, management companies, such as IBM, create customizable templates that allow developers to make allowances for differences in APIs and are able to deploy and migrate workloads. 

## Portability of workloads 

Discussing APIs and standards is essential because workload management is fundamental to the operation of a hybrid cloud. In a hybrid cloud environment, being able to move workloads around and optimize them based on the business problem being addressed is critical. Despite the fact that workloads are abstracted, they are built with middleware and operating systems. In addition, workloads must be tuned to perform well in a specific hardware environment. 

Another challenge is that a majority of workloads in the cloud are virtualized with hypervisors such as KVM, VMware, and PowerVM. Each of these virtualization implementations are different and will impact the portability of workloads. In today’s hybrid cloud world, a lot of manual intervention is needed to achieve workload portability. However, in the future standards and well-defined approaches will hopefully make hybrid cloud workload management a reality. 

## Managing and Monitoring Workloads 

To support the needs of the business with a hybrid cloud environment requires that considerable attention be paid to how workloads are managed and monitored. Increasingly, organizations depend on these environments to support their internal teams as well as partners and suppliers. Without careful management and monitoring of the required workloads, the organization can’t achieve the right level of support and service the business demands.
