The rise of hybrid cloud

Hybrid cloud is a cloud computing environment which uses a mix of on-premise private cloud and public cloud services with seamless orchestration between platforms. While some of the organizations are looking to put selective IT functions on to a public cloud, they still prefer keeping the higher-risk or more bespoke functions in a private/on-premise environment. This is what we can call a hybrid cloud solution. It is not necessary to go the whole mile, for example - some organizations use cloud services for archiving old data but keep operational data closer to within the organization.

Best-fit infrastructures

Sometimes the best infrastructure for an app requires both - cloud and dedicated environments. That's why we need to create a truly hybrid environment - so that an organization can connect public cloud, private cloud and the dedicated hardware to create the best fit for the desired business needs. - that are:

Public cloud for cost effective scalability, ideal for heavy or unpredictable traffic
Private cloud for complete control and security aspects
Dedicated servers for super-fast performance and reliability

A hybrid cloud configuration offers the following features:

Flexibility; the availability of both scalable, cost effective public resource and secure resource can provide better opportunities for organizations to explore different operational avenues
Cost efficiencies: Public clouds are likely to offer significant economies of scale (such as centralized management) and greater cost efficiencies than the private cloud. Hybrid cloud model therefore allow organizations to unlock these savings for as many business functions as possible and still keeping sensitive operations secure
Security: The private cloud feature in the hybrid cloud model not only provides the security where it is required for sensitive operations, but can also meets regulatory requirements for data handling & storage where it is applicable
Scalability:Although private clouds offer a certain level of scalability based on the configurations (whether they are hosted externally or internally), public cloud services do offer scalability with less boundaries as resources are pulled from the larger cloud infra. By moving as many non-sensitive functions as possible to the public cloud infrastructure, this would allow organizations to benefit from public cloud scalability even as reducing the demands on a private cloud.

Hybrid cloud is particularly valuable for highly changeable / dynamic workloads. For example, a transactional order entry system which involves significant demand around the holiday season is a good hybrid cloud candidate. The application could run in private but can access additional computing resources from a public cloud when there is a spike in computing the demand. To connect both public and private cloud resources, this model requires a hybrid cloud environment.

Another hybrid cloud use case is big data processing. An organization, for example, could use hybrid cloud storage to retain its test, accumulated business, sales and various other data, then run analytical queries in the public cloud, which can scale to support the demand in distributed computing tasks.
