A Virtual Data Center (VDC) is a collection of virtualized resources and machines that belong to a specific tenant and reside within a single physical data center. VDCs are designed to provide cloud-based infrastructure that allows users to deploy and manage their computing resources efficiently and flexibly. These virtual environments mimic the operations of a traditional data center while offering the advantages of scalability, cost-effectiveness, and agility.
There are two main types of Virtual Data Centers:
An Allocation VDC is characterized by resource limits (quotas) that are assigned for specific resources such as CPU, RAM, and storage.
Allocation VDCs are ideal for organizations that need predictable resource usage and prefer to set limits on their consumption of resources to manage costs effectively.
A PAYG VDC operates on a consumption-based model, offering greater flexibility by assigning an unlimited quota for CPU and RAM.
PAYG VDCs are typically used by businesses with fluctuating or unpredictable resource requirements, as it allows them to scale up or down as needed and only pay for what they use.
Virtual Data Centers provide a flexible, scalable, and cost-effective solution for businesses looking to manage and deploy virtualized resources. With two types—Allocation and PAYG—organizations can choose the model that best suits their operational and financial needs. The allocation model is suitable for businesses requiring fixed resource caps, while the PAYG model offers unlimited resource consumption with billing based on actual usage.
Both models offer robust storage policy management, allowing businesses to balance resource consumption and cost control within their virtual environments.
