Cloud Services For Dummies, IBM Limited Edition  42 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. 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. Portability of workloads Managing and Monitoring  Workloads 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. 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.
