Moving to the cloud can raise more questions than answers. Do I move and improve to Infrastructure as a service, or redesign my business processes on Software as a Service. This presentation covers several cloud migrations to OAC, EBS/Cloud (HCM/Financials) and Hyperion, and outlines what went well and what could have gone better.

What this
session IS
We will go over the various “Cloud” types
Discuss how Cloud is used to mean different things
Understanding these options, pros and cons
Talk about leveraging cloud-based architectures
• What works well
• What works less well
Applies to many products (on-Prem and Cloud)
• Hyperion, JDEdwards, EBS, PeopleSoft, DRM,
OBIEE/OBIA

What this
session is
NOT
Not a specific guide for your organization
This is not one-size-fits-all
Deeper conversations needed
• You can’t be an expert in 40 min.

Oracle vs other definitions
Decision Matrix
Workload considerations
Extras – Backups, Cloning, Encryption

What have we seen…

Typical Cloud Getting Started Mentality
Traditional Silos
• Physical
• Dedicated
• Static
• Heterogeneous
Consolidated
• Virtual
• Shared platform &
shared
infrastructure
• Dynamic
• Standardized
platform &
infrastructure
Private Cloud
• Self-service
• Auto-scaling
• Metering &
chargeback
• Capacity planning
Public Cloud
• Specialized
• Shared
• Standardized
Hybrid Cloud
• Federation across
public & private
clouds
• Interoperability
• Cloudbursting

11. www.datavail.com 11
Multiple definitions out there
Types of Cloud or XaaS
• FaaS
• SaaS
• PaaS
• DBaaS
• IaaS
• Hosting
• AMS
Oracle calls these all Cloud,
others have different definitions

13. www.datavail.com 13
FaaS – Function-as-a-Service
This is a future option
Buy only what you use
Channel by Channel, instead of cable or dish lineup
SaaS – Software-as-a-Service
Bundled functions into a service
Application that is developed/ported into a shared
infrastructure model
Data, applications are typically stored outside your
firewall

14. www.datavail.com 14
PaaS
Think of this like an SDK (Please don’t shoot me for the
over-simplification)
Develop, run, and manage applications without needing
to manage the infrastructure
Plug-and-play modules to enhance capabilities quickly
Used to enhance or extend SaaS solutions
Also sometimes used to describe on-prem applications
on IaaS
Platform-as-a-Service

15. www.datavail.com 15
DBaaS – Database-as-a-Service
Quickly stand up a database, create some tables and
upload data
IaaS – Infrastructure-as-a-Service
Think servers
Bare metal options
Pre-build OS
Get a desktop or server up and running quickly

16. www.datavail.com 16
Hosting
Putting your on-premises
server/DB/app onto someone
else's hardware
Could be a virtual or physical
move
Could be a rack, or a VM
Third party that you contract to manage
your server, DB, application, services
etc.
Some of these work together, others
build on one another
AMS
Application Management Services

17. www.datavail.com 17
Which to use?
When the off-the-shelf product will meet your needs
Commodity services
Limited or no customizations
Extensions ok (PaaS)
Operating budget is available
CapEx is not available
Limited interfaces, self-contained business processes
SaaS

18. www.datavail.com 18
Can be in your cloud, or a provider
Quick deployments
Avoids expensive or complex architecture
Convention tools may be limited
Which to use?
PaaS

19. www.datavail.com 19
Major players are Oracle, Amazon, Google, Microsoft
Provides a server (may contain OS, web server etc)
Workloads are quite variable
• High usage for short periods of time
• Can be turned off at night, weekends, outside peak
periods
Need quick provisioning
User self service
Which to use?
IaaS

20. www.datavail.com 20
Decision Matrix SaaS
Can business processes be changed to conform
to the application?
Standard processes across the globe
Limited interfaces/data loads
Reporting needs are minimal
Do you own your data? Can you locally store it
later?

21. www.datavail.com 21
Decision Matrix IaaS
A set of questions to help understand the workload
being considered
Not all workloads are suitable for the cloud
Best to derive a formula to determine suitability
Based on workload, costs, availability, need to flex
CPU, memory, storage

22. www.datavail.com 22
Decision Matrix Hosting
Can the service be provided outside of your data
center?
Allow providers to clone/backup/test DR
Many will include BIOS, OS, Java patching
Ability to grow and shrink CPU, memory, storage
needs
Data location/data privacy concerns

23. www.datavail.com 23
Decision Matrix AMS
Many times hosting/AMS can be combined for
cost savings
May include application/database level patching
Concerns about who has access to the data
Cloning of complex applications like EBS
Provide Level 1 and Level 2 support
More team focused on enhancement backlog

24. www.datavail.com 24
Workloads are high and consistent
Considerable customization or
extensions are needed
Legal/compliance reasons around
requiring data stored on site
You have the staff and expertise to
support it
Existing software licenses are already
paid for
Workload Considerations
May be best to wait for next upgrade
cycle
Business processes are not
standardized
Capital vs Operating expense
Cloud is not always the cheapest
Those were ‘Cloud’ options. On-premises is better when:

25. www.datavail.com 25
Extras to
consider
Backups
Who is responsible for the backups
BR/DR – how are your backups tested
Storage and retrieval needs
High Availability – Can you staff and afford clusters, RAC,
etc?
Cloning – creating dev/test environments
Encryption – many providers include encryption in their
offerings
Testing – do you have a testing solution or strategy?

26. www.datavail.com 26
Compliance
Issues
Multi-tenant Concerns
• Are you sharing hardware, data bases?
Data Privacy – is the data PII, PCI, HIPAA?
Data Location
• Moving to a data center down the street
• May not be that simple for compliance
• Contracts are often written with language:
• Internal data stores
• Specific addresses
• “Owned” by company

27. www.datavail.com 27
What have
we seen…
One size does not fit all
Workloads were a small consideration
Application affinity is a larger consideration
Product maturity was a large driver
Willingness of the business to change processes
to comply
Misunderstanding of what cloud providers actually
provide
Management tools across solutions are lacking

28. www.datavail.com 28
If you are using HR Modules
HR/HCM
Many complex integrations, best of breed
Oracle HCM product very mature
• Exception payroll – outsource that
Moving module by module
• Time and labor
• Recruitment
• Compensation
• Benefit tracking
Working to establish core HR
SaaS is commonly the direction

29. www.datavail.com 29
If you are using Finance
Accounting (AR/AP/GL) Planning
and Budgeting
Cloud offerings in subledger and project
accounting are not there yet
EPM products have matured a lot in the past
year
Many integrations - reporting needs are
huge
Steady workloads
Iaas/Hosting/AMS is commonly the direction

30. www.datavail.com 30
If you are using
Manufacturing
Manufacturing/Logistics
If core to your business
• Customizations are your differentiator
• Iaas/Hosting/AMS is the direction
If not core to your business
• Look for operational cost savings
• Leverage new features/capabilities as
deployed
• SaaS is the direction

31. www.datavail.com 31
In Summary
Be sure to understand which XaaS
makes sense, and maybe none do!
Understand your workload
List out the extras that come with
the service, not just the functionality
Compliance issues - think like a
lawyer
