After attending last week’s All About the Cloud, Satish Shenoy shared a summary about the Public, Private and Hybrid Clouds Presentation
Speaker: Treb Ryan, CEO, Opsource
Key Topics covered: Private vs. Public Cloud – Pros & Cons; What is the answer?
Presentation – Summary Points:
• Choice of Rhino as our “masot” – A Rhino might not be able to see too far into the future but it certainly charges forward.
• Dimension Data takes on cloud announcement in Feb 2012.
• Why disdain for Private Cloud?
o Because it doesn’t offer….
-Immediacy
-Ubiquity & Mobile
-Collaboration – Info sharing, innovation
-Infinite (never a question of out of storage or other resources)
o Sold by hardware guys
-Designed to maximize hardware/software sales – Hardware sold whether they have ability to provide private clouds or not
-Capex, Capex, Capex – Upfront costs – You should be able to pay for something only when you use it
o Innovation and Compatibility Lags
-Private cloud providers software releases are on a different scale (a year vs. the “normal” of weeks/months)
• Issues with Public cloud
o Dave Sovereignty
-Some data cannot reside in anywhere we want…there are laws where data should reside
o Latency Issues
-7 ms latency times need
o Customization
-Someday we will get whatever we want in the public cloud in what is now available in the private cloud.
-Variety is lacking in the public cloud
-In private cloud – you can tweak cloud requirements for certain apps, etc
• Then what is the answer
o Give people private instances within the public cloud
o Always compatible with the public cloud environment
-In a private environment you need to be in perfect sync with your provider
o Disadvantage:
-Sometime you turn on the tap and there is nothing there and you need to find out where to find some.
• Audience Q:
o If you are my ISV,
-Critical things to think about are data sovereignty and latency issues
-Multi-tenant SaaS apps,
-When you write your app, think about future expansion – write your apps for regions and locations
-Important part is where the data sits in terms of data sovereignty and latency issues
o We offer two options – Private cloud within one of our centers, Private cloud in client’s own data center
Heard at the session (Interesting Quotes):
• “(With private clouds) once again, I see hardware turn to shelf-ware”
• “I have disdain for private clouds”
