A hybrid cloud is a combination of both public and private clouds. In a hybrid cloud environment, the public cloud is used to perform non-critical tasks, whereas the private cloud is used to perform critical tasks. The hybrid cloud is used by government agencies, financial organizations, healthcare, etc.

The hybrid cloud combines both cloud environments, which helps an organization choose the particular cloud environment to manage their workload. 

There is multiple hybrid cloud provider such as Google Cloud Platform, Cisco, Amazon Web Services, IBM, NetApp, Microsoft Azure, etc.

Benefits of Hybrid Cloud

1. Reliability: Hybrid clouds are more reliable because the alternate cloud can be used as per the business requirement.
2. Secure: It is easy for an organization to perform non-critical tasks on the public cloud and critical tasks private cloud, as the private cloud offers greater security as compared to the public cloud.
3. Scalability: Public clouds are more scalable, and resources can be easily added and removed as per the organization's needs.
4. Cost Effective: Hybrid clouds are cost-effective since organizations don’t need to buy all IT infrastructure and equipment.
5. Risk Management: Hybrid cloud environment provides an efficient way for organizations to handle risks.

Disadvantages of Hybrid Cloud

1. Infrastructure Compatibility: Since a hybrid cloud is a combination of both the cloud environment, both have different compatibility. It is challenging to make them compatible by running them on different stacks.
2. Networking: Networking is a bottleneck issue when there is data transmission between the public and private clouds. The public cloud is slow, which affects the performance level significantly. 
3. Security:  Security is an important issue for any cloud environment. Due to this, it should be made sure that cloud services are compliant with the organization's security policy.
4. Investment: Hybrid cloud are inexpensive in operations term, but it is not totally dependent on the public cloud. So for private cloud, it needs an experienced cloud architect to manage the cloud environment and hardware resources, which are costlier than the public cloud environments.
