The term “hybrid cloud” refers to an infrastructure that is a combination of on-premise server infrastructure and different cloud based solutions. Not all applications are “cloud ready” or suited and must therefore be maintained in an on-premise infrastructure. We refer to a mixture of cloud and on-premise infrastructure as a “hybrid cloud”.
Hybrid cloud allows organizations to get the best of both worlds, choosing the best solution by each application or system.
- Combined benefit of private and public infrastructures.
- This includes increased efficiency and the flexibility to meet disparate needs.
- Building a hybrid cloud with private infrastructure that’s directly accessible greatly reduces access time and latency in comparison to an public cloud services.
- Flexibility in designs.
- Particularly valuable for dynamic or highly changeable workloads.
- Integration of applications and security can attract a higher management overhead.
- Dilution of knowledge – multiple vendors can result in loss of control over systems knowledge.
- Security risk is increased as credentials may not be integrated or synchronised
- Systems can be “detached” if poorly implemented.
- Complex licensing model that can be cumbersome to manage and can potentially introduces duplicate costs.
- Can opt for the best value solution based on each application or data set
- Can become more expensive if integration of systems is not properly handled
- Can increase complexity of design and therefore increase operational costs
