Definition from Microsoft: A hybrid cloud is a computing environment that combines a public cloud and a private cloud by allowing data and applications to be shared between them. When computing and processing demand fluctuates, hybrid cloud computing gives businesses the ability to seamlessly scale their on-premises infrastructure up to the public cloud to handle any overflow—without giving third-party data centers access to the entirety of their data. Organizations gain the flexibility and computing power of the public cloud for basic and non-sensitive computing tasks, while keeping business-critical applications and data on-premises, safely behind a company firewall.
Using a hybrid cloud not only allows companies to scale computing resources, it also eliminates the need to make massive capital expenditures to handle short-term spikes in demand as well as when the business needs to free up local resources for more sensitive data or applications. Companies will pay only for resources they temporarily use instead of having to purchase, program, and maintain additional resources and equipment that could remain idle over long periods of time. Hybrid cloud computing is a “best of all possible worlds” platform, delivering all the benefits of cloud computing—flexibility, scalability, and cost efficiencies—with the lowest possible risk of data exposure.
Most businesses today even if they have a significant amount of the architecture on premise will have some form of hybrid cloud – this could be in the form of their Office 365 environments or storage or even the way that their accounts departments use Sage. This is because a significant amount of applications that businesses use daily are accessed from environments outside of their networks, ironically sometimes without the knowledge of IT.
Quiss work with many businesses that have a hybrid solution where their IT is a mix of private, public and on premise managing and advising on deployments, applications, security, hardware etc. Handling these environments can have its own issues with security being a primary risk, our experience and knowledge will support an organisation if after consideration this is the chosen deployment methodology.
