1. JOnAS on Windows Azure

JOnAS is an Open Source OSGi certified J2EE application server, hosted by OW2. Bull
provides a technical support through subscriptions.
Windows Azure is the public Platform as a Service Cloud from Microsoft. Yes VMs are
Windows Server, but Azure runs tons of Open Source software and applications written
in .Net for sure but also in PHP and Java.
JOnAS runs like a charm on Windows Azure and takes benefits of the Platform as a
Service concept and the high SLA level and availability of Azure. JOnAS allows the
deployment and execution of JavaEE/OSGi applications in production on Azure

4. Running JOnAS on Windows Azure
● Same instantiation mechanism used as for .net applications
1. The application is managed as a “Role”, an assembly of VMs running a cluster
connected to a load balancer
2. The role is configured and controlled either programmatically or using the console
3. A new VM is created from a Windows Server image, then the application & middleware
are downloaded from a Blob and installed on the image.
4. The management & update of the underlying infrastructure & Operating System are
totally automated & applied without service interruption

5. How much does it cost ?
● It’s cloud based pricing, based on consumption of resources
● But you can also use subscriptions or an enterprise agreement
● All prices are public and there is an online calculator available
● An example : A cluster of 2 Jonas servers, running on bi-core VMs with 3.5GB of
memory, accessing a 500GB storage space with 1 million of transactions and 1
Tera bytes of traffic will cost $581 per month based on standard prices
JOnAS $581
NLB per month
list price
1 Tera Bytes 2 VMs - 2 x 1.6GHz Storage 500GB
traffic 3.5 GB Mem 1 million accesses

6. Next Steps of the project
● Today the clustering technic used is the « farm » concept. JOnAS servers do not
know each others. Maybe it could be interesting to test the JOnAS clustering.
● Test the performances of JOnAS on Azure virtual machines, in order to delivers
performance figures.
● Connectivity with SQL Azure to take benefits of the SQL database service
● Build an automated installation of new applications and updates on existing
JOnAS clusters
