PIM4Cloud
What is PIM4Cloud?
UML profile for
describing IT systems deployment to cloud platforms
from an application designer perspective
Inputs from different partners
SOFTEAM
Enterprise Architecture approach and TOGAF modeling initiative
Tecnalia
SINTEF

Why PIM4Cloud?
Need to describe a deployment to
cloud platforms at UML level of abstraction
Why not UML deployment diagrams?
3
Too generic!
Cloud specific concerns:
• Geographical distribution?
• Public, private hosting?
• Instantiation of new computation resources?
• Packaging of Virtual Machines to host an IT system?
• Automatic deployment of Virtual Machine images?
• Generation of deployment scripts?
• Help in migration from one provider to another?
Which cloud layer should PIM4Cloud
focus on?
Infrastructure as a Service (IaaS):
a platform virtualization
environment as a service.
Platform as a Service (PaaS):
a computing platform and
solution stack as a service.
Software as a Service (SaaS): software as a service over the
Internet.
Different Issues for each layer.

Infrastructure as a Service
Platform as a Service
Software as
a Service
Why isn’t PIM4Cloud at PaaS/SaaS
levels? Cloud platforms at these layers are all significantly
different.
They propose different libraries, language mechanisms,
scalable data storage means.
This all is on the design level, not on the deployment
level!
5
Again, why is PIM4Cloud at IaaS
level?
Great similarities between IaaS cloud platforms:
computation and storage resources,
virtual machine images,
APIs.
IaaS technical domain is currently stable.
It is time to develop systems!

Conclusion
The PIM4Cloud language
Support the Designer of a Cloud based Application
High-level design of the deployment architecture
Current state UML Profile / Meta-model + Modeling Tool
Perspectives
Proactively developing the specification and issue PIM4Cloud RFP
at OMG
Support for code generation aimed at cloud computing platforms
Fully automated deployment

More on Big Data Support
What are Big Data Systems?
Dominated by the amount of data and
the speed in which it must be processed
This is an important subset of cloud applications!
Why is it complicated?
Current platforms do not
provide real-time guarantees
New platforms: NoSQL Databases
In terms of modeling…
