Hybrid cloud technology is the middle path in the cloud computing world. Some experts predict that hybrid cloud technology will be the future of enterprise computing, while others are skeptical about the efficacy of integrate disparate systems and arriving at a hybrid cloud scenario that works.
But, what is this hybrid cloud? Hybrid clouds attempt to integrate in-house and outsourced computing and network resources. The perceived advantages of hybrid cloud technologies are many.
- The architectural concept is compelling. Customers can move between virtualized servers within the local data center and remote data center. Load balancing between on premise and public cloud servers can be effectively and efficiently managed from a single interface that allows the user pick out the location of the VM based on cost and SLA information.
- Hybrid clouds are flexible. Users can decide what goes on the public or private cloud on the fly and can allocate different elements of an application to internal or external environments.
- Hybrid clouds integrate primary storage with the cloud interface to create a single highly available, accessible system. Replication of data is consequently, made simpler and Disaster recovery is provided for with greater ease.
Hybrid cloud computing adoption processes—for that matter any kind of cloud computing—is hard work. The adoption process may require iterative discussions at all levels of the organization for buy-in. The enterprise must take out the time to identify the resources that may be migrated to the cloud. For instance, if the resource has high availability requirements and response time, cloud latency issues may have to be considered before the resource is migrated to the remote data center.
The internal and external platform integration will have to be evaluated during the adoption process. The internal and external platforms must be similar for seamless integration. Most often, the platform is used to open up the ticket to the external cloud and monitor workloads to be processed. Integrations can be created at application levels by using SOAP or SOA based approaches. However, the necessary APIs of the two IT infrastructures are exposed to each other for creating the connection and integrating the applications.
To summarize, hybrid cloud technology is attractive for a variety of reasons, but adoption is hard work. Enterprises must learn how to build the hybrid cloud storage solution using the available market tools taking into consideration the data categories and needs of the enterprise and the integrations aspects of the technology. Success or failure of the adoption of the hybrid cloud will emerge from the process re-engineering that goes into the creation.
