In this blog post, I'm going to briefly introduce the WSO2 Private PaaS , an upcoming product from WSO2. Even though I'm writing about this now, the WSO2 Private PaaS term coined just few weeks after we donated WSO2 Stratos to Apache Foundation in June 2013. Apache Stratos (incubating) and WSO2 Private PaaS The WSO2 Private PaaS is built on top of the Apache Stratos (incubating) project, which is currently undergoing major architectural changes from the initial 3.0.0-incubating version. Following are few major changes you can expect in the next Apache Stratos (incubating) release. i.e. 4.0.0-incubating version. Using a message broker for communication among core Stratos components. Auto scaling now analyze real time data from cartridges like in flight request count and load average. Currently this data is analyzed using  WSO2 Complex Event Processor Load Balancer is now a cartridge in Stratos New Stratos Manager UI Stratos Manager now has RESTful servic...

Recently, WSO2 proposed the "Apache Stratos" as an incubating project at the Apache Software Foundation. The vote for Stratos proposal started about a week ago. We are really excited to hear the news that voting has passed less than 20 hours ago and Apache Stratos project is now officially in the incubator. Apache Stratos will be a polyglot PaaS framework and it will be possible to run on any IaaS supported by jclouds . Interestingly, the jclouds is also currently an Apache incubating project. The proposed Apache Stratos committer list includes developers from WSO2, Cisco, SUSE, Citrix, NASA Jet Propulsion Lab (JPL), Sungard and Engine Yard. I'm really happy that I'm also in the initial committer list!! :) We recently released the Stratos Foundation 2.0 GA, which will be the last release of "Stratos" from WSO2. The Stratos 2.0 GA release is also featured in many technology web sites such as InfoQ , JAXenter , BusinessWire ,  Kavis Technol...

In my previous post , I explained how to install OpenStack in Multi-Node environment with DevStack. If you want to install the OpenStack in a Single Machine, you can follow the same steps for the Controller Node Installation in my previous post. You can omit the "MULTI_HOST=1" line from the localrc. For example, following is a "localrc" configuration used to install OpenStack in a single machine. HOST_IP=10.100.0.29 FLAT_INTERFACE=eth0 FIXED_RANGE=192.168.17.0/25 FIXED_NETWORK_SIZE=126 FLOATING_RANGE=10.100.0.64/28 ADMIN_PASSWORD=labstack MYSQL_PASSWORD=root RABBIT_PASSWORD=rabbitmq SERVICE_PASSWORD=supersecrete SERVICE_TOKEN=token

These days we are preparing to release WSO2 Stratos 2.0 PaaS Foundation and we needed to install OpenStack in multiple nodes in our lab environment. In this guide I'm going to explain how to install OpenStack Folsom using the DevStack script [1] and also how to install additional Compute Nodes. Installing OpenStack was not an easy task. I spent last 5 days to install and configure the OpenStack and tried various guides. Earlier we used Damitha's  guide  to Install OpenStack Essex on a single node [2]. Then we followed different guides. Finally we decided to try the DevStack script, which is a great option to install and run an OpenStack cloud in a local development environment. Using Nova Network This guide uses the Nova Network instead of the Quantum Network plugin. I followed a really good guide  [3] at NetworkStatic.net, which also use the Nova Network. Quantum Network Plugin is bit complicated and we need two physical network interfaces. I'm p...
