The most interesting part of the presentation was a list of the “Nine Myths of Cloud Computing”:
- Myth #9 - Cloud computing is not new, not revolutionary
- Myth #8 - All clouds are the same
The speaker noted that there are many different types of clouds including: public, private and hybrid. He felt that in the long run, most companies would end up with hybrid solutions, running what is appropriate for each type of cloud.
- Myth #7 - Cloud computing is about technology
Marcello walked through a slide of Forrester info on traditional data center vs a cloud-based solution. He focused on expense, financial risk and depreciation, noting that cloud computing is also about cost.
- Myth #6 - Private clouds have no benefit over virtualization
The speaker felt that private clouds had to deliver self-provisioned capabilities. At Unisys, the average setup time for a developer went from 10 days to 5 minutes due to the creation of a self-service web-based UI.
- Myth #5 - Cloud computing is not reliable
Marcello disagreed with this myth, focusing on having a disaster recovery strategy, data security requirements, data reliability (using ‘m’ of ‘n’ redundancy strategies)
- Myth #4 - Cloud value is only about cost
Don’t let the improvement in agility get lost in the message
- Myth #3 - Cloud is not for mainstream business applications
Marcello felt that cloud computing won't take off until this myth dies
- Myth #2 - Cloud is inappropriate for compliance-regulated industries
If architected properly, can address all kinds of compliance issues
- Myth #1 - Internal datacenter is more secure than the cloud
Overall, quite an interesting presentation; certainly some hype around the cloud, but good list nonetheless.
