Hybrid Cloud vs. Converged Cloud: Comparing 2 cloud options


There is still confusion about cloud. There, I said it.  After reviewing white papers and marketing collaterals I noticed there is some confusion between hybrid cloud and converged cloud. This material was written by industry watchers and marketers. These are people who work with Cloud every day. Some people inter-changeably use converged cloud and hybrid cloud as if they have the same meaning.  Some do not know what converged cloud means.  So, I wrote down what I think the differences are between these two terms:


Hybrid cloud is a combination of private, managed and public cloud deployment models. 


Converged Cloud is HP’s terminology that has special connotation regarding to our unique approach:

  • Convergence of various deployment models: private, managed, public cloud and traditional IT  
  • Open, extensible and integrated by design so that applications and workloads can be portable across the various deployment models  
  • One consistent management, consumption and user experience across all models.  No cloud silos, no separate tools for different cloud models. 


The difference is more than skin deep


Another way to think about the difference is that an organization can have hybrid cloud, which results in possibly islands of cloud that don’t talk to each other. This means data is not transportable, apps are not portable and you may have different management tools for different cloud models.


Converged Cloud treats the various deployment models as one (hence convergence) set of resources even though the underlying sourcing models may be different.  This is critical for organizations that are embracing and investing in cloud computing now and years to come. 


As businesses evolve, their demands to serve their customers properly may evolve and their IT environment needs to adapt to the changing needs of the business.  Converged Cloud offers the flexibility and portability of the applications and critical business data, as well as the confidence and consistency in delivering the right services to the end users over time.


Most cloud vendors today talk about hybrid cloud as a mix of private and public cloud. They focus on what they have to sell to get customers to build hybrid cloud. Unfortunately, they do not emphasize the risk of establishing ‘cloud silos’ where your data and applications may be locked into a specific cloud deployment model.  They also don’t discuss how to remove your data and applications from these environments.


Which cloud solution gives you what you need, when you need it?


Let’s say you build an application on your private cloud, and you need to scale beyond its capacity to meet seasonal demand. You need to ‘burst’ to a temporary pool of public cloud resources. Can your application run on the public cloud?  What if you are expanding your business in other countries and you need to put the same applications you are running in-house today to run on a different environment? 


Application and data portability are key. Cloud silos are bad. That’s why HP sees the future of cloud computing as hybrid and yet ‘converged’ to prevent silos, data and technology lock-in and ensure flexibility and consistent user experience. That is why we developed Converged Cloud, to give our customers true freedom.
