It had already started and is now spilling over into 2015. Now, Hybrid Cloud is the most favored solution due to cost-effectiveness and low security risks. Hybrid Cloud combines both public and private (on-site) cloud services, and is considered as the best solution for concerns involving dependence on public services and security risks. On-site services are usually associated with high costs, maintenance, and support required throughout the application lifecycle.
Public and private cloud services talk to teach other through technology that enables data and application portability. Some of the components involved are cloud-native applications, application migration, and cloud management platform.
The range of benefits afforded by hybrid solutions are:
- Providing the ability to burst (scale up and down) as required by applications or data.
- Including multiple public clouds. The right cloud can be the one which is closer geographically, cost-effective, or higher performing.
- Including distinct or single public and private clouds. For example, an organization might use a public cloud service (storage service) for archived data but continue to maintain in-house (private) storage for mission-critical customer data.
- Speedily moving critical applications including data and analytics, e-commerce and customer-related services to hybrid cloud environments. This mainly relieves enterprises the concerns related to storage and scalability.
The main purpose of having a hybrid cloud is to have the facility to move workloads from a private cloud to a public cloud when needed. There can be various reasons, for example, a private cloud maintenance outage or more demand for computing resources. The cloud platforms used in private and public clouds must be able to execute applications and process data successfully to ensure efficient movement of workloads between clouds.
This is achieved by executing same cloud platforms or platforms that have application programming interface (API) which is shared. For example, OpenStack, an open source cloud framework is available for private clouds. Numerous public cloud vendors have started using OpenStack, including Rackspace, IBM, and HP.
The goal to drive towards, during a hybrid cloud deployment is to minimize change. The greater the differences between the public and private cloud environments, the more difficult it will be to manage multiple clouds as a single entity.
A hybrid cloud strategy has to first pick one of two starting points: public or private cloud. Your pick could determine whether an IT model is efficient and economical.
