What is Hybrid Cloud?
Hybrid Cloud is an architecture that uses a mix of on-premises private, public and third-party cloud services whereby you get on-demand access to software and services. This type of cloud computing uses three requisites to be considered as a Hybrid Cloud –
- Infrastructure as a service (IaaS),
- Construction of a private cloud, or co-location hosting with a private cloud service provider.
- Wide Area Network (WAN) connectivity between those two premises.
In layman’s term, a hybrid cloud is a platform by which you can manage and consume public and private cloud IT resources as one.
How does Hybrid Cloud work?
A hybrid cloud provides an “orchestration” layer that allows the user to move data, applications, software, information or resources across the private cloud to public cloud and vice versa. Architecture, security, and management principles and procedures are very similar, if not identical between the two platforms.
Why you should consider a Hybrid Cloud strategy?
Public clouds keep organisations data on third-party service providers. This reduces operational and maintenance costs for the enterprise. Nonetheless, some organisations think that their data and applications are no longer under their ownership. If the third-party service provider encounters service interruption or downtime, the organisation would not be able to access their applications or data.
Changing service providers in the event of interruption is a costly and time consuming exercise. A hybrid cloud strategy enables organisations to mitigate these risks whilst taking advantage of the benefits that public cloud services provide.
The business benefits of public cloud services are important to keep up with the non-stop demands of digital innovation. With a hybrid cloud strategy you primarily get the best of both cloud worlds. Deploying a hybrid cloud is a low-cost way to get extra capacity when you need it. Application workloads and data that are best hosted in a on-premise private cloud environment do not need to change. Access and integration of the on-premise applications and data to public cloud services enable organisations to deliver innovative digital solutions to their customers.
The crucial factor of considering a hybrid cloud approach is evaluating the available deployment options based on workload and data requirements. Hybrid cloud strategies avoid the compromises that may arise from adopting either a pure public cloud strategy or a no-cloud strategy.
Hybrid Cloud Benefits
Business Continuity and Stability
If your requirements demand the highest levels of availability and stability then you are most likely going to require complete control over all IT system elements. This includes appropriate change control and governance across all layers of the technology stack.
This level of control may be impossible to achieve when using public cloud services as the public cloud provider is typically responsible for the management of the cloud. In some cases, changes and modifications to system components supporting the cloud services will be executed with little or no customer engagement.
Hosting workloads that require complete control of the IT environment in a private cloud provides this level of control. Integrating highly available environments to cloud services to augment with non-critical functionality is a great way to achieve the availability and innovation objectives of the organisation.
Extra Opportunity for Innovation
In the past, businesses need to spend on infrastructure, provisioning and management to provision application and system environments. In some cases this requires considerable effort to predict the required capacity and workloads – which in many cases will be unknown until the development process has commenced.
A hybrid cloud allows business to test concepts without capital disbursement. They can create a prototype in a cloud environment, develop, evaluate and destroy if required with minimal delay or lengthy capex procedures.
In one way or another, your digital business will grow so does your need for more IT infrastructure. Expanding IT infrastructure can be extremely costly and time consuming. Provisioning to support innovation places pressure on precise forecasting particularly when procurement of infrastructure or software licenses is required.
Nonetheless, a hybrid cloud environment provides the opportunity for business to augment their on-premise capacity with cloud services until accurate capacity metrics are defined.
Deploying automation procedures on the cloud provides the ability to expand resources up and down as the business demands vary. This permits the hybrid cloud system to take advantage of limitless resources based on demand-driven usage, improving the environment for effectiveness and performance.
Improved Speed To Market
In many companies, environment delivery speed is a crucial factor in supporting digital innovation and launching new products. Organisations who can both innovate at speed at low cost, without interruption to existing systems, have a distinct competitive advantage in the marketplace.
A well implemented hybrid cloud strategy supports both speed to market for new products and the stability and performance required to retain customers.
Most organisations need to consider the security implications of placing their data in a public cloud. Lax security controls or procedures can easily result in sensitive data being publicly available on the internet. Nonetheless, a private hybrid cloud system allows for more control the location and security of sensitive data.
