Data, Storage & Their Impact
Private or Hybrid Cloud
Storage: “Leak” issues in
hybrid clouds and
performance issues relating
to storage/server siting
Out-of-Cloud
Storage: No
special risks
Public

Public Cloud
Storage: Data
security and

considerations
Cloud Storage vs. DBMS
• You may not have a choice with PaaS or
SaaS models
• Cloud DBMS systems let you leave storage
management to the cloud
• Cloud DBMS systems may pose
performance and compatibility risks, and
be harder to manage
• Persistent storage in the cloud is the
largest issue in management and security!
Summing Up
• You need a specific business case, and to know
how cloud commitment will address it
• You need to understand the value of public,
hybrid, and private clouds
• The various as-a-service models will differ
considerably in terms of what you have to do to
support them and how to manage and secure
them
• Data storage issues are all too often ignored;
don’t make that mistake!
