For the first few years that cloud was becoming prominent, it was praised by IT and finance professionals. However, those who were working with extremely sensitive or mission-critical systems remained reluctant to use the technology. What enterprises started to do was strike a balance and adopt the hybrid model, rather than going all-in with either in-house or public systems.
A hybrid cloud is an integrated cloud service utilizing both private and public clouds to perform distinct functions within the same organization. All cloud computing services should offer certain efficiencies to different degrees but public cloud services are likely to be more cost-efficient and scalable that private clouds. With a hybrid cloud, an organization can maximize their efficiencies by employing public cloud services for all non-sensitive operations, only relying on a private cloud where they require it, with it ensuring that all platforms are seamlessly integrated.

Hybrid cloud refers to a mixed computing, storage, and services environment made up of on-premises infrastructure, private cloud services, and a public cloud such as Amazon Web Services (AWS) or Microsoft Azure with orchestration among the various platforms. Using a combination of public clouds, on-premises computing, and private clouds in your data center means that you have a hybrid cloud infrastructure.
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 fluctuate, 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 datacenters 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.
Often, hybrid cloud refers to a combination of a public cloud service and a private cloud on-premises; however, hybrid clouds could also consist of two public clouds provided by different providers or even a combination of a cloud and traditional IT. Actually, a setup where existing systems on a traditional IT infrastructure are combined with a public cloud service is currently the most frequent use case of a hybrid cloud.
Hybrid cloud enables an enterprise to use a broader mix of IT services. For example, a business might run a mission-critical workload within a private cloud, but use the database or archival services of a public cloud provider.
Means, the public cloud’s pay-as-you-go scalability is ideal for heavy or unpredictable traffic and can reduce IT costs. When you need enhanced security and ultimate control for business-critical apps and data, incorporate a private cloud. The performance with single-tenant dedicated servers, you get ultra-fast performance, security, and reliability, on bare metal machines. A hybrid cloud approach can unify these two approaches can provide a cost-effective secured solution for business
Hybrid cloud use case is big data processing. A company, for example, could use hybrid cloud storage to retain its accumulated business, sales, test and other data, and then run analytical queries in the public cloud, which can scale a Hadoop or other analytics cluster to support demanding distributed computing tasks.
Despite its benefits, hybrid cloud computing can present technical, business and management challenges. , which requires substantial expertise from local IT staff and cloud architects. The implementation of additional software, such as databases, helpdesk systems, and other tools can further complicate a private cloud. What's more, the enterprise is fully responsible for the technical support of a private cloud and must accommodate any changes to public cloud APIs and service changes over time.
Moreover, there may be potential connectivity issues, service-level agreements (SLAs) breaches, and other possible service disruptions. To mitigate these risks, organizations can architect hybrid cloud workloads that interoperate with multiple public cloud providers. In some cases, an enterprise needs to redesign workloads slated for hybrid cloud to address specific public cloud providers' APIs.
Moving to a hybrid cloud can save money and make your organization more efficient and agile. Public clouds are likely to offer more significant economies of scale such as centralized management, and so greater cost efficiencies than private clouds. Hybrid clouds, therefore, allow organizations to access these savings for as many business functions as possible whilst still keeping sensitive operations secure.
