There is a reason why Hybrid cloud computing happens to be the most preferred cloud computing model. Even when compared to public and private cloud computing models, Hybrid cloud has some really good advantages which attract most of the businesses.
In our previous cloud post, we discussed the advantages of deploying the Hybrid Cloud Computing model and how a hybrid of public and private model could be the best option for a company. But the Hybrid cloud model is no different to others. Similar to Public and Private, Hybrid cloud also comes with its own set of disadvantages. We enlist Three major drawbacks a company could face when deploying the Hybrid cloud model.
1. Infrastructure Dependency
In case of an outage, the organization has to rely on the internal IT for any support to handle the outages in the hybrid environment. One of the ways to reduce it would be to create redundancy across its data centers. In order to mitigate the risks, the company may have to use multiple cloud services.
2. Security compliance
Ensuring that all the cloud services; both public and private, are compliant with the company’s security policies and more importantly, abiding the regulations set by their respective governed bodies. The data transferred between any of the cloud services are protected against any misdeeds. Any negligence on this part could defeat the purpose of deploying the hybrid cloud model.
3. Networking
Having a network setup which ensures fluid and effortless transfer of data is the key in Hybrid model. The involvement of public and private cloud would invariably make networking in the organization quite complex, which needs to be handled in the most effective manner possible.
4. Cost
Although a business can easily setup a public cloud for a low cost, the same cannot be said for the private cloud model. Building the private cloud can increase the cost, and the cost is bound to increase in future as the business keeps growing. A clear strategy for the perfect combination of public and private clouds are required to bring this cost to the minimum.
Conclusion
Irrespective of it drawbacks, for many organizations the Hybrid cloud model may still appear to be the best option when compared with the Public and Private cloud model. Given that Security and Uninterrupted smooth transfer of data remain of paramount importance, Hybrid cloud model may be exactly what they are looking for.
But the enterprise has to have a clear view of handling the complex SLA’s (specifically the compliances) involved with all the cloud services, an equally complex networking, and a perfect model for controlling the company’s infrastructure.

Assembling a private cloud to handle a standard workload, with burst compute offloaded to the public cloud, can be a long-term budget-friendly arrangement. I think that it provides us with flexibility, simplicity and practicality.
