The PIM4Cloud modeling language has been developed by SOFTEAM and its partners during the REMICS FP7 project. In this presentation we motivate this language; describe its current state; detail an case study; and discuss about its future developments.
1. PIM4Cloud
A PIM for Cloud Application Engineering

2. 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

3. Why PIM4Cloud?
Need to describe a deployment to
cloud platforms at UML level of abstraction
Why not UML deployment diagrams?
Cloud specific concerns:
• Geographical distribution?
• Public, private hosting?
• Instantiation of new computation resources?
• Packaging of Too generic!
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?

4. Which cloud layer should PIM4Cloud
focus on?
Software as
Infrastructure as a Service (IaaS): a Service
a platform virtualization Platform as a Service
environment as a service.
Platform as a Service (PaaS): Infrastructure as a Service
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.

5. 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
6. 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!

Metamodel UML Profile
Image Type Description
CloudApplication Application whose architecture is based on the use of a
cloud computing platform.
CloudProvider Service provider of a platform for cloud computing.
PublicCloud Public cloud computing platform, provided by an external
provider.
PrivateCloud Private cloud computing platform installed and managed
directly by the end user.
CloudResource Collection of resources provided by a cloud computing
Set platform.
CloudResource Generic resource provided by a cloud computing
platform.

19. 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?
LHC (Hadron Collider)
Current platforms do not 300 Gb/s filtered 300Mb/s
provide real-time guarantees
New platforms: NoSQL Databases
In terms of modeling…
