Nowadays, more and more businesses are turning to a managed hybrid cloud model which mixes and matches dedicated hardware, public cloud services, and private cloud platforms to meet their unique requirement.
It is defined as a composition of two or more distinct cloud infrastructures (community, private or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (National Institute of Standard and Technology).
The primary benefit of a hybrid cloud is agility. Now the core principle of a digital business is the need to adapt and change direction quickly. Many enterprises need to combine private cloud, public cloud and on-premises resources to gain the agility it needs for a competitive advantage.
Users can use the easily scalable public cloud for their dynamic workloads while leaving more sensitive, workloads to a private cloud. Users might store sensitive financial or customer information on their private cloud and use the public cloud to run the rest of their enterprise applications. When the company runs some of their big data analytics using highly scalable public cloud resources while also using the private cloud to ensure data security and keep sensitive big data behind their firewall. A hybrid cloud lets users allocate public cloud resources for short-term projects at a lower cost than if they used their own data center’s IT infrastructure. This cloud could let users match their actual data management requirements to the private cloud, a public cloud that is best able to handle. Hybrid cloud allows users to take advantage of emerging cloud technologies, while still retaining their legacy applications within their corporate data centers.
The hybrid cloud absorbs the benefits of both the public cloud and the private cloud. It delivers the fast connection and easy-to-access features of the public cloud and the high-security features coupled of the private cloud. The hybrid cloud can capitalize on a similar low-cost approach as the public cloud. Besides that, it can integrate the public cloud computing with onsite cloud hardware which delivers control of security and regulations in the hand of the company. More than that, it will operate behind a firewall and offer scalability to handle fluctuating computing demands. It means it may down to the private cloud or scale up to use the public cloud.
The hybrid cloud approach allows components and applications to interoperate across boundaries, between cloud instances, architectures. The same level of distribution and access flexibility is needed for data. It includes some characteristics such as users with the data center, private, public cloud resources and workload are tied together under common data management while staying distinct. Users can connect existing systems running on traditional architectures that run business-critical applications or contain sensitive data that might not be suited for the public cloud.
There are a lot of hybrid cloud providers. For example, Amazon Web Services hybrid cloud includes networking, security, storage, and management tools, Dell EMC Hybrid cloud has main aim to help companies with the largest workload to achieve efficiency with digital transformation.
In conclusion, the hybrid cloud becomes more and more important with the development and helpful for operation in a digital environment.
