Workload Categories For Private Cloud
Private Cloud use cases generally fall into 3 different categories of workloads.
Transient
A transient application is one that is used infrequently, exists for a short time period or is used for a specific task/need and the discarded. This type of workload is appropriate for a Pay As You Go allocation model in VMware vCloud Director.
Highly Elastic
An elastic application is one that is dynamically growing and shrinking its resource consumption as it runs. An example of this would be a retail application that sees dramatically increased demand during holiday shopping seasons, or a travel booking application that expands rapidly as the fall travel season approaches. This bursty type of workload is appropriate for the Allocation Pool model in VMware vCloud Director.
Infrastructure
An infrastructure application is one that tends to run all the time at a predictably steady state. Examples of these include a print server, directory server, an e-mail relay server or systems monitoring engine. This type of workload is appropriate for a Reservation Pool model in VMware vCloud Director.
