What Well Cover

• Cloud targets of opportunity
• Public, hybrid, private
• SaaS, PaaS, IaaS
• Application Models
• Storage models

How Clouds (Might) Save Money
Maintenance Costs Fall
Faster Turn-On to New Projects
Better Resource Efficiency/Utilization
Cash Flow Is Improved
Compliance/Security Improved
4
The Three Business Models
Suitable Apps Maintenance (HW, SW, support) Quick Start Efficiency Cash Flow Management and Compliance
Public Limited Excellent Excellent Excellent Excellent Newer Issues Up Front
Hybrid Broad Good Good Good Good Fewer Issues
Private Almost All Primarily HW Benefits Reduces HW Setup Good Good Few New Issues
5
The -as-a-Service Options
Your Role Most Common Applications Primary Benefit Case Primary Issue
Software as a Service Setting up parameters and using Personal productivity, non-mission-critical Substitute service for internal IT Breadth of service, credibility of supplier
Platform as a Service Maintaining application images for platform Business apps extending a local middleware framework Specific application support and hybrid applications Matching platform to application needs
Infrastructure as a Service Maintaining full machine images Development, offload, all others Most flexible, general Managing machine images
SaaS models look like hosted services, IaaS/PaaS
models look like a data center

How Cloud Applications Might Look
Virtual Infrastructure
Mash-Up Hybrid
Client-to-Cloud
Public Cloud
Private Cloud
7
Data, Storage Their Impact
Private or Hybrid Cloud Storage Leak issues in
hybrid clouds and performance issues relating to
storage/server siting
Public Cloud Storage Data security and
performance considerations
Out-of-Cloud Storage No special risks
Public Cloud
Private Cloud

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!

9
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
  dont make that mistake!
