run constantly, such as an online commerce site or a control system that manages a critical environmental process.  Business services and various application models are added  into the mix as well. In a hybrid cloud environment, your workloads may be running on different clouds, and running different kinds of  infrastructure using different operating systems. You’re bringing together workloads from different environments that  often have to behave as though they’re a unified system. Now you may think that all you have to do in a hybrid cloud environment is to get some automation software to  automatically schedule resources and to perform some other  functions associated with allocating resources and you’re  done. However, do consider some issues when thinking about  how to create a hybrid cloud environment that both performs  at a quality level and meets security and governance requirements. For example, say a workload is being used within a geography  that has different rules for where data must be placed. If the  data has to be stored within a country, then that workload has  to be managed differently than the same workload running in  a country without this kind of governance requirement. With  fewer restrictions, IT operations is free to move workloads  to locations that have the bandwidth or capacity to meet the  quality of service the business needs. In fact, the ability to  change and move workloads based on business requirements  is at the heart of operational issues in the cloud. There are different kinds of workloads that you work with  in the cloud, and while balancing workloads may not be a  problem when you have a homogenous workload running in a  particular cloud, like a public cloud for e-mail, things can get  more complicated as you try to bridge different environments.  That’s where portability and standards come into play.
