Hybrid cloud is an integrated cloud service model that employs two models: public cloud and private cloud. But deploying hybrid cloud isn’t like implementing one public cloud and one private cloud. Implementing hybrid cloud computing into your business involves certain integration and migration challenges. Some companies use public and private clouds for different business functions. But that is not a hybrid cloud! A cloud model is hybrid when a business uses public platform for sending data to a private cloud or data center. Therefore, it becomes imperative for enterprises to understand how hybrid cloud is beneficial for them, how to deploy this model, and how it can drive business agility.
By leveraging hybrid cloud, a business can:
Manage sensitive business applications/data on-premise but interconnect them to a business intelligence platform on public cloud.
Send non-critical applications or data to the public cloud for greater flexibility and higher scalability.
Tap into public cloud IT infrastructure resources and save big investments made in sole private clouds.
Deploying hybrid model
While hybrid cloud delivers business agility, reduces operating costs, and provides higher scalability on-demand, its implementation requires careful analysis and systematic approach. Three critical factors essential for successful implementation of hybrid cloud includes:
Secure cloud architecture: Enterprises need secure cloud architecture so that it can replicate the security features of private clouds into the public cloud. A business must consider operational security measures, VPN connection, data encryption, ownership of server keys, and third party access management in its hybrid cloud.
User Access Control (UAC): The hybrid cloud model must have a User Access Control (UAC) system. This will help your hybrid cloud to set permission levels for users asking for access to the data centers of your enterprise. When businesses use UAC, vendors can only access sandbox environment but not corporate networks.
Automating self-service and self-defined networking: Your virtualized infrastructure should be created upon a self-service portal to manage service levels defined by your IT department. With automated self-service interface, a business gets financial transparency and self-service admin capabilities such as security policies and VPN connections. Software-defined networking helps users to create a bridge between public cloud and dedicated private resources.
Enterprises and organizations are leveraging hybrid clouds for its agility, lower costs, greater control, and improved SLAs. Apart from the hybrid cloud deployment requirements mentioned above, companies should consider parameters such as cloud bursting, disaster recovery, and other core set of IT capabilities for successfully implementing this model. Examining the experiences of a cloud vendor and taking cloud technology advisory services, enterprises can better select the right hybrid cloud service provider. Post done by Fred
