The Cloud computing trend is increasingly commoditizing and delocalizing several different elements of the computing stack. It all started with Infrastructure as a Service (IaaS) and Software as a Service (SaaS) but companies are starting to quickly understanding and leveraging the value of Platform/Middleware as a Service (PasS/MaaS). Cloud Messaging is an example of PaaS/MaaS services at the foundation of virtually all cloud-applications. This webcast will introduce the use case for cloud messaging, and will demonstrate how a very efficient Cloud Messaging solution can be built end deployed on a public or private cloud using OpenSplice DDS and its technology ecosystem. This presentation explores the technical and business benefits deriving from the use of OpenSplice at the foundation of a Cloud Messaging solution.

3. Cloud Computing
☐ Cloud computing is the delivery of
computing as a service rather than

a product
☐ Cloud computing provides
virtualized hardware, middleware,
software, data access, storage, etc.
OpenSplice DDS
☐ Cloud Services do not require end-
user knowledge of the physical
location and configuration of the
system that delivers the services –
like in power-grids

4. Cloud Computing Stack
Cloud Based Delivery Stack

☐ Established with IaaS and SaaS, Software as a Service (SaaS)
Cloud computing is now
quickly expanding into PaaS Platform as a Service (PaaS)

Middleware Platform as a Service (PaaS)
OpenSplice DDS
Infrastructure and Hardware Infrastructure as a Service (IaaS)
☐ Functionally, the Cloud Computing stack mirrors the traditional stack
☐ Yet, not all the layers of Cloud Computing (e.g. PaaS) are mature or
available as COTS offering

6. PaaS
Cloud Based Delivery Stack
☐ Gartner identifies into PaaS the

such as:
☐ Enterprise Application Integration Platform as a Service (PaaS)
☐ Messaging

☐ Data Bases
☐ Application Servers Infrastructure as a Service
☐ …

7. Public vs. Private Clouds
Copyright*2011,*PrismTech*–**All*Rights*Reserved.
☐ Although most of the hype is Cloud Based Delivery Stack
on public clouds, most of the
deployments are today on Software as a Service (SaaS)
private clouds
OpenSplice DDS
☐ OpenSource infrastructures Platform as a Service (PaaS)
are more and more available
for easily set-up and run Infrastructure as a Service (IaaS)
private clouds
