Hybrid cloud architecture is a configuration in which organizations utilize both in-house systems, such as proprietary servers, and cloud services, either public or private. This combination enables organizations to store sensitive data in-house for security purposes and use the cloud's scalability and cost efficiency for other workloads.
For instance, a company may keep confidential customer information in-house within its local systems while using the cloud to run a website or process bursts of additional traffic. This would give the business flexibility, efficient resource use, and savings.
