What is a hybrid cloud?
A hybrid cloud—sometimes called a cloud hybrid—is a computing environment that combines an on-premises datacentre (also called a private cloud) with a public cloud, allowing data and applications to be shared between them. Some people define hybrid cloud infrastructure to include "multi-cloud" configurations where an organisation uses more than one public cloud in addition to their on-premises datacentre.
What are the benefits of hybrid cloud computing?
No matter which definition of hybrid cloud you use, the benefits are the same: When computing and processing demand increases beyond an on-premises data-centre's capabilities, businesses can use the cloud to instantly scale capacity up or down to handle excess capacity. It also allows businesses to avoid the time and cost of purchasing, installing, and maintaining new servers that they may not always need.
Are there regulatory issues with using a hybrid cloud model?
For industries that work with highly sensitive data, such as banking, finance, government, and healthcare, using a hybrid cloud model may be their best option. For example, some regulated industries require certain types of data to be stored on-premises while allowing less sensitive data to be stored on the cloud. In this kind of hybrid cloud architecture, organisations gain the flexibility of the public cloud for less regulated computing tasks, while still meeting their industry requirements.

Are there security issues with hybrid cloud infrastructure?
Organisations that use a hybrid cloud platform are able to take advantage of many of the same security measures that they use in their existing on-premises infrastructure—including security information and event management (SIEM) capabilities. In fact, some organisations find cloud hybrid security to be superior to that of their on-premises datacentre because of capabilities such as automated data redundancy, high availability, disaster recovery, and other robust cybersecurity features.
