Hybrid Cloud
Hybrid Cloud is a cloud infrastructure model in which computing resources are distributed between a private cloud or on-premises infrastructure and a public cloud, while being managed within a unified architecture. A hybrid cloud allows different environments to be combined based on security, performance, cost, and scalability requirements.
In a Hybrid Cloud model, some workloads and data are hosted in a private environment, while others run in a public cloud. Integration, network connectivity, and unified management processes are established between these environments. This approach is widely used in corporate IT infrastructures where maintaining control over critical data while leveraging the benefits of public clouds is essential.
How Hybrid Cloud works
A hybrid cloud is built by connecting on-premises infrastructure or a private cloud with one or more public cloud providers. Secure network connections are configured between environments to enable data exchange and service access.
Applications and services can be distributed across environments in different scenarios. For example, sensitive data and business-critical systems may remain on-premises, while compute-intensive or peak workloads are offloaded to the public cloud. Resource management is often performed through centralized orchestration and monitoring platforms.
Hybrid Cloud vs other models
Hybrid Cloud differs from a private cloud in that it uses public cloud resources for scaling and cost optimization. Unlike a public cloud, the hybrid model allows part of the infrastructure to remain fully under the company’s control.
Hybrid Cloud is also different from a multi-cloud model. In a hybrid cloud, the key element is the integration of private and public environments, whereas multi-cloud involves using multiple public clouds without a mandatory on-premises component.
Use cases for Hybrid Cloud
Hybrid Cloud is widely used in enterprise environments, the financial sector, telecommunications, and by large service providers. It is applied to host corporate systems, databases, analytics platforms, and business applications.
Typical scenarios include backup and disaster recovery, scaling for peak workloads, meeting regulatory requirements, and gradual cloud migration without a complete infrastructure redesign.
The role of Hybrid Cloud in IT strategy
Hybrid Cloud is often considered a compromise and evolutionary approach to cloud transformation. It allows organizations to adopt cloud technologies gradually without abandoning existing investments in on-premises infrastructure.
Hybrid Cloud also increases IT strategy flexibility by enabling architectures to adapt to changing workloads, business requirements, and regulatory constraints.
Advantages of Hybrid Cloud
Key advantages of Hybrid Cloud include:
- a combination of control and flexibility
- cost optimization through the use of public cloud resources
- scalability for peak workloads
- compliance with security and regulatory requirements
- the ability to migrate to the cloud in stages
At the same time, Hybrid Cloud requires a more complex architecture and higher demands on management, security, and network integration.
FAQ
