Two years back, I disparaged hybrid clouds in my blog: "Why Hybrid Clouds Look Like my Grandma's Network". Since then the pain and necessity of many clouds in business environment has become acute. I see a great similarity between Hybrid Clouds and Bring Your Own Device (BYOD) phenomenon that has become well-accepted in today's organization. IT tried to resist it initially, but the consumer movement proliferated into the workplace and was hard to control. Hence IT had no choice but to follow along.
A similar movement is emerging in Cloud. After Amazon Web Services (AWS) made it simple for application developers to swipe credit cards to buy compute and get up and running in a jiffy, the addiction has been hard to stop. Enterprise stakeholders are consuming cloud infrastructure by the hour and in the process running up total costs for their organizations and leaving gaping holes in security and compliance. But this time around, IT has an opportunity to get ahead of the phenomenon.
Challenges with existing hybrid cloud approaches:
Vendor lock-in: It is hard to argue against the flexibility offered by public clouds. However, few realize that the flexibility comes at the cost of vendor lock-in. Public cloud APIs are typically custom and moving the workload back is almost impossible.
Skyrocketing costs:Granted that public cloud vendors have been driving down costs. However, using public cloud for regular application deployments is like using a rental car for long-term use. If you need a car temporarily, say during a vacation, it makes sense to rent it by the day. However, when you are back at home and need a car for everyday commute, using a rental car will run up costs. This is what enterprises are running into when public cloud charges for resources and bandwidth start to add up. However, it is hard to get out once you are locked into operational practices and workload customization in your favorite cloud.
Security & Compliance holes:Security, what security? When you don't even know what workloads are running in public clouds and you have no control over who accesses them and how, it is needless to say how big a security and compliance hole this is.
The Solution: Embrace Bring Your Own Cloud (BYOC), build hybrid clouds with Intercloud Fabric
Now that we agree that there's no way around folks bringing their own clouds, IT needs to provide choice to users while driving consistency, control and compliance for its own sake. Here's how Intercloud Fabric make this possible:
Choice:Intercloud Fabric enables IT to support a number of clouds including giant public clouds (Amazon, Azure) or their favorite cloud provider including Cisco Powered.
Consistency:Although users get choice of clouds, IT can maintain consistency in networking, security and operations. This is made possible by seamless workload portability across clouds, say vSphere to AWS while maintaining enterprise IP addressing and security profiles.
Compliance:Since public clouds appear as an extension of enterprise data center, current compliance requirements like logging, change control, access restrictions continue to be enforced.
Control:IT controls the cloud in a good way. They don't have to say "No" to their end users in consuming diverse clouds but can still manage them with a single console and move workloads back and forth.
Seem too good to be true?
