Best of both (The Hybrid Cloud)
In the quest for solutions that are practical to manage and offer the flexibility and security that modern businesses demand, there always seems to be a trade off between isolating solutions vs opening them up. For a business this means finding the balance between the efficiencies of cloud deployments and the control of in house systems.
Gartner, Inc. defines a hybrid cloud service as a cloud computing service that is composed of some combination of private, public and community cloud services, from different service providers.
How does a hybrid cloud work in reality and what are some of the trade-offs one can expect from adopting this approach. Most business have embraced virtualisation as a means to add new software environments as their needs grow and evolve, if a new solution requires a server, a virtual machine is started. When truly dissecting cloud based solutions there may only be a few exceptions where a solution needs to be deployed on bespoke hardware across nodes in a cluster, most solutions can be run on single server instances albeit sacrifice distributed performance and fallback etc. With this in mind there is a definite use case for SaaS based applications moving to a hybrid based approach to accommodate specific customer needs where inside the firewall deployment is a priority.
The resistance of SaaS providers to offer on premise solutions is well founded and in most cases offering on premise solutions goes against the very philosophy and value adding benefits that the SaaS providers have set out to achieve. Benefits like economies of scale, continuous updates and distributed load balancing are compromised when deploying on a customer’s premises. But what if customers prize inside firewall security, reduced latency and self managed environments over other benefits, then one can expect that the benefits passed on to the customer from scaled SaaS deployments such cost reductions, zero server maintenance and failover to be compromised as a result. Like with most traditional on premise solutions there will be a premium for adopting this type of deployment.
The hybrid cloud tries to bridge the gaps between delivering cutting edge web based solutions and in house managed solutions. Companies can close these gaps by offering virtual machines with the same operating systems that would be used with purely on cloud deployments. By SaaS providers deploying on these internal environments they can still leverage the power of the modern web while satisfying in house IT teams in order to land the traditional enterprise Sales deals.
