WSO2Con 2011: Panel: Cloud and SOA: The good, the bad and the uglyService-oriented architecture (SOA) and the cloud complement each other and at the same time are in different stages of their lifecycles. At WSO2Con 2011, Paul Fremantle, WSO2 co-founder and CTO, led a panel to discuss three aspects of these technology approaches. First was an examination of SOA, which has been through the hype cycle and out the other side, and how hindsight here might help understand cloud computing. Second, was to examine the interaction between SOA and the cloud, and third was to look to the future and what is next. Joining Mr. Fremantle were panelists Sastry Malladi, eBay distinguished architect; Brad Svee, Concur Technologies senior manager of IT development and engineering; Narendra Nathmal, Cognizant Technologies Advanced SOA Center of Excellence chief architect; and Afkam Azeez, WSO2 director of architecture. Here are highlights from their discussion. Moderator: Paul Fremantle, Panelists: Sastry Malladi, Afkham Azeez, Brad Svee, Narendra Nathmal WSO2Con 2011: Panel: Data, data everywhere: big, small, private, shared, public and moreIt has been said that data has a value that will last much longer than the systems it runs on. Today that data is more diverse than ever, whether it’s coming from Google, Facebook, RFID tags, GPS devices, or traditional applications. The challenge to effectively store, manage and access all these forms of information has in turn spawned a correspondingly diverse range of data storage and management technologies. At WSO2Con 2011, Dr. Srinath Perera, WSO2 senior software architect, led a panel to address two primary questions. How can we store data at a time when we are no longer talking about 10MB but instead 10TB? And how do we make sense of all the information we are collecting? Joining Dr. Perera were panelists Dr. C. Mohan, IBM research fellow; Gregor Hohpe, Google engineer; and Sumedha Rubasinghe, WSO2 architect and senior manager. Here are highlights from their discussion.

In the process, we’re setting ourselves up for failure. WSO2Con 2011: Building Cool Applications with WSO2 StratosLive - Selvaratnam UthaiyashankarPlatform-as-a-service (PaaS) compliments infrastructure-as-a-service (IaaS) offerings by providing middleware products as services to enable application development and integration in the cloud. However, not all PaaS approaches are the same. Many only support Web application development, and only a few can support complex enterprise applications in the cloud. In his presentation at WSO2Con 2011, Shankar explored cloud-native benefits, such as self-provisioning, multi-tenancy, elasticity and metering, and he used the WSO2 StratosLive PaaS to demonstrate how to build complex SOA applications for the cloud. Here are highlights from his talk. About the Speaker
WSO2Con 2011: Open Source Middleware for the Cloud: WSO2 Stratos - Afkham AzeezIncreasingly, enterprises are turning to the cloud as a cost-effective way to extend the reach of their applications. However, Gartner forecasts that vendors will not have true, integrated and complete middleware platforms and platform-as-a-service (PaaS) frameworks until 2015. In his presentation at WSO2Con 2011, Azeez explored basic cloud middleware platform and PaaS principles, using WSO2 Stratos and WSO2 StratosLive as examples. About the Speaker
WSO2Con 2011: Multi-tenancy: Winning Formula for a PaaS - Dr. Srinath PereraOrganizations are turning to cloud computing because it allows for resource pooling, minimizes capacity planning, can scale to meet an enterprise’s growing needs, and enables the specialization of services. However, achieving these benefits means going beyond running virtual machine instances—which are resource and time intensive—to deploying full multi-tenancy. At the same time, implementing a multi-tenant platform or service requires a trade-off between sharing and isolation. In his presentation at WSO2Con 2011, Srinath discussed levels of multi-tenancy, how the WSO2 platform delivers multi-tenancy, and why multi-tenancy is critical when implementing a platform-as-a-service (PaaS). Here are highlights from his talk. About the Speaker
Usage Metering and Throttling in Cloud ComputingThis article describes how to do usage metering and throttling in a cloud environment by taking WSO2 Stratos as an example. Also, this includes information about measurable parameters and how we can use them for throttling How WSO2 Products can be Used to Create and Invoke a Proxy Service through a Mobile ClientThis article describes a usecase which demonstrates how the WSO2 ESB can be used with BlackBerry client. You can also do many things inside this proxy service like calling actual Web services, mediate message, logging, message reformat etc.
