Hybrid IT
What is
HYBRID IT
IT strategy is complex. Sometimes the correct solution is a private cloud on-premises and
sometimes its a public cloud off-premises.
What if your needs are not cut-and-dried? What if
what is needed is the best of both worlds? Hybrid IT empowers blending the control of a private cloud with the agility of the public cloud – it is fully customizable.
Overview
HOW IT WORKS
Hybrid IT is when datacenter resources reside both on-premises plus in a public cloud. The combination is a hybrid of both locales. A hybrid blend of resources for infrastructure platforms unlocks the flexibility of both. There are almost unlimited resources available on demand in the public cloud, as well as emerging private clouds.
These additional resources can provide great scalability and agility benefits when applications require burst capabilities. Thus, with a hybrid IT model, your data and applications can reside where they best meet your organization's service level requirements, while leveraging key advantages and benefits of both public cloud and on-premises compute resources.
WHY YOU NEED HYBRID IT
Capacity on Demand
When the ability to flex IT resource capacity is needed without long term commitments or if you lack immediate resources to scale up, implementing a hybrid strategy is advantageous. Both public and private clouds, including "everything-as-a-service" models (XaaS, EaaS), have matured enough to drastically reduce complexity.
You can maintain and provision resources while enabling scale up or down capacity within minutes. There is no upfront commitment to purchase capacity (over a baseline in the case of private clouds), it simply fluctuates as needs dictate. For example, if demand is seasonal and “bursty”, consider this model as an option, especially private cloud, which can be less costly for many workloads that are required to run 24/7 or most of the time.
