WSO2 Gadget Server and WSO2 Mashup Server .next

0 comments

Written by Tyrell



The WSO2 Mashup Server, still the only true Free and Open Source Mashup platform in the industry will see its 2.1.0 release alongside Carbon 3.0.0 - Irridium. Highlights for this release include ...
  • Carbon 3.0.0 - Irridium as base platform
  • Hierarchical mashup deployment (mashups deployed under user work spaces)
  • New HTTP client Host Object to retrieve any resource over the internet, supplementing the Screen Scraper and WSRequest Host Objects and
  • numerous fixes and improvements as suggested by users in our forums 



We are almost there with version 1.1.0 release of the WSO2 Gadget Server and Nuwan, a key member of my team has done a nice round up of the latest features and improvements we've done for this release. To highlight ...
  • We are powered by Carbon 3.0.0 - Irridium
  • Latest stable revision of Apache Shindig
  • Pub/Sub and i18n for Gadgets and
  • HTTP mode portal (in case you haven't noticed we ran the portal on HTTPS in previous releases, which was not a must, since Gadgets themselves come from HTTP sources.)
I'm also working on an article explaining inter Gadget communication with pub/sub that I hope to publish in the WSO2 Oxygen Tank right in time for the release.

We are at the beta testing stages of the release cycle and are hoping to announce the final release within the next couple of weeks.

Step 1: Go to layout settings in your blogger.com blog and click "Add a Gadget".




Step 2: Click "Add your own" and type the gadget URL as http://gsdemo.wso2.org/registry/resource/system/gadgets/soa.xml

(This gadget is hosted in the WSO2 Gadget Server demo instance at http://gsdemo.wso2.org)




Step 3: Change gadget settings if required and click "Save".



Step 4: Save your layout. Now the latest posts from the SOA Platform Blog will be visible in your blog. And the beauty of this particular gadget is that your viewers can read the SOA Platform Blog's posts without leaving it :)

Written by Sami

If you are using C++ as the choice of programming language for you Web services implementations, rather than assuming the default C++ performance advantage, you might want to dig a bit deep to see what the best options are.

This article publishes some performance test results for C++ Web services.

Autoscaling (Axis2) Web Services on Amazon EC2

0 comments

Written by Afkham Azeez

Fault tolerance, high availability, & scalability are essential prerequisites for any enterprise application deployment. One of the major concerns of enterprise application architects is avoiding single points of failure. There is a high cost associated with achieving high availability & scalability. We will look at an economical approach towards automatically scaling Web service applications while maintaining the availability & scalability guarantees at an optimum economical cost. This approach, involving the Amazon EC2 cloud computing infrastructure, makes it unnecessary to invest in safety-net capacity & unnecessary redundancy.

The Web service application developer should only need to write the application once, and simply deploy it on the cloud. The scalability & availability guarantees should be provided automatically by the underlying infrastructure.

Autoscaling refers to the behavior where the system scales up when the load increases & scales down when the load decreases. Auto-healing refers to an approach where a specified minimum deployment configuration is maintained even in the event of failures. Such an approach is essential for cloud deployments such as Amazon EC2 where the charge is based on the actual computing power consumed. Ideally, from the clients' point of view, in an autoscaling system, the response time should be constant and the overall throughput of the system should increase.

We will describe in detail an economical approach towards building auto-scaling Apache Axis2 Web services on Amazon EC2. In the course of this thesis, we will introduce well-known address (WKA) based membership discovery for clustering deployments where multicast-based membership discovery is an impossibility.

We will also introduce an approach towards dynamic load balancing, where the load balancer itself uses group communication & group membership mechanisms to discover the domains across which the load is distributed. In a traditional setup, a single load balancer fronts a group of application nodes. In such a scenario, the load balancer can be a single point of failure. Traditionally, techniques such as Linux HA have been used to overcome this. However, such traditional schemes have quite a bit of overhead and also require the backup system to be in close proximity to the primary system. In case of catastrophic situations, this approach can result in complete failure of the system. We will introduce an auto-healing scheme in case of load balancer failure using Amazon Elastic IP addresses & a load balancer group, which can overcome these shortcomings.
