| | DECEMBER 20199CIOReviewmost of the challenges of private/ public cloud mentioned above. Some benefits of Hybrid IT are in improved efficiency, greater flexibility, lower costs, and finally increased speed to market.However, the challenges in this also is worth noticing--integration of cloud and on-premise applications, migration of workloads between environments, management issues on frameworks and data availability, and security challenges.To offset these challenges, before moving to Hybrid IT, there are some of the questions you need to ask. These include what workloads should we move to private/public cloud, what is the baseline resource consumption we should consider for provisioning resources, how will applications perform in the cloud relative to their on-premises performance, what are the likely resource contentions, and what is the most resource-effective way to run a specific workload?What are the measures to design and manage Hybrid IT?To design an effective Hybrid cloud, consider the following--Operations:Clearly define the infrastructure (network, cloud computing, and social media) as concisely as possible. Now implement a decision-making framework that is interactive and flexible. Next review and adjust resource skills to match the new focus on service management rather than delivery. IT employees will need better managerial, analytical, and risk management skills to evaluate and validate vendors.Controls:Need to implement the right controls and audit processes to ensure the selected vendors are delivering as promised and that their services are secure. In case of vendor failure, will the business be financially affected and will the expectations of the key stakeholders be met?Sourcing:Evolve an efficient vendor sourcing model to address a constantly changing vendor landscape. Along with this, you need a rigorous sourcing program to manage significant relationships with smaller vendors rather than a couple of large vendors. Finally you require a different contractual arrangement and redefined service levels.In conclusion, Hybrid IT is the new reality. It is time for vendors and IT organizations to accept it and make sure it is designed well, workloads are effectively balanced between the various clouds, and traditional IT hosting and Operational controls are put in place to maximize the benefits. Businesses can leverage hybrid it by optimizing the mix of public cloud, private cloud, and on-premises solutions
