Cloud Clustering: Benefits of Utilizing Multi-Cloud Virtualized Clustering for the Enterprise
Physical Clusters are practically becoming obsolete in the evolving corporate modern world because of augmented drawbacks. There is a growing need to deplete the dependency factors of organizations because of the fact that ubiquitous access to Cloud resources easily enables the simultaneous use of different resources. Cloud based virtualized clusters are making the usability of the multi-Cloud platforms over a single Cloud easier along with salability, resource provisioning and leveraging of the compute intensive problems that are the primary issues in Cloud based environments. Unlike the physical nodes of clusters, the Cloud based virtualized cluster nodes can be provisioned with resources from different Clouds to improve the cost-effectiveness of hardware and software stack.
Virtual clusters are also facilitating the enterprises to avoid the useless major investments related to hardware, specialized installations of cooling and power efficient systems along with personnel to operate and control the specialized hardware. Multi-cloud development also comes with multifarious challenges, related to the lack of a cloud interface standard because the distribution and management of the service master images and the cross platform interaction between the service components is a difficult tasks for most of the start-up level Cloud customers. Using a computing cluster constituting multiple Cloud services there are better results depicted in the practical domains in terms of availability and avoidance of outages in the crunch cases,. Cloud also lets us to dynamically deploy new cluster nodes in different vicinities to avoid the degradation of the cluster performance.
Virtual clusters are normally built with VM’s installed in multiple entities at the backend servers using the distributed setup of physical clusters but this approach is not what we call “purely virtualized”. A combinational strategy of using the physical and virtual Cloud based clustering is will not serve the purpose because there will be increased risks of complexities at the back end resulting in lack of QoS. The VMs in a virtual cluster are logically connected by a virtual network across multiple networks thus increasing resource provisioning. Another pronounced effect of Cloud based clustering is the ability to activate multiple number of nodes within a virtual cluster with an option to have dynamic, shrinkable and flexible capacity to switch between them just like an overlay network a peer-to-peer network.
Cloud clustering comes with great challenges and a need of adaptation of efficient strategies. Effective strategies for managing VMs running on physical computing nodes are a must if the enterprise is really looking forward towards a competitive edge in the performance outputs.
