What is Hybrid Cloud and its benefits
Hybrid
Cloud refers
to the cloud infrastructure environment that is a mix of public and private
cloud solutions. The resources are typically orchestrated as an integrated
infrastructure environment. Apps and data workloads can share the resources
between public and private cloud deployment based on organizational business
and technical policies around security, performance, scalability, cost and
efficiency, among other aspects. For instance, organizations can use private
cloud environments for their IT workloads and complement the infrastructure with
public cloud resources to accommodate occasional spikes in network traffic. As
a result, access to additional computing capacity does not require the high
CapEx of a private cloud environment but is delivered as a short-term IT
service via a public cloud solution. The environment itself is seamlessly
integrated to ensure optimum performance and scalability to changing business
needs.

Advantages
of Hybrid Cloud to business organizations include:
- Flexible policy-driven deployment to distribute workloads across public and private infrastructure environments based on security, performance and cost requirements.
- Scalability of public cloud environments is achieved without exposing sensitive IT workloads to the inherent security risks.
- High reliability as the services are distributed across multiple data centers across public and private data centers.
- Improved security posture as sensitive IT workloads run on dedicated resources in private clouds while regular workloads are spread across inexpensive public cloud infrastructure to tradeoff for cost investments.
Suitable
choice for:
- Organizations serving multiple verticals facing different IT security, regulatory and performance requirements.
- Optimizing cloud investments without compromising on the value proposition of either public or private cloud technologies.
- Improving security on existing cloud solutions such as SaaS offerings that must be delivered via secure private networks.
- Strategically approaching cloud investments to continuously switch and tradeoff between the best cloud service delivery model available in the market.
Limitations:
- It can get expensive.
- Strong compatibility and integration is required between cloud infrastructure spanning different locations and categories. This is a limitation with public cloud deployments, for which organizations lack direct control over the infrastructure.
- Additional infrastructure complexity is introduced as organizations operate and manage an evolving mix of private and public cloud architecture.
The
choice between public, private and hybrid cloud solutions depends on a variety
of factors, use cases and limitations. In the real-world, it’s not an either/or
situation, especially since organizations tend to leverage all three types of
cloud solutions considering the inherent value propositions and tradeoffs.
