    Cloud Computing Hype

    Why is everyone talking about cloud computing? Drawn-out, expensive IT projects that are planned andimplemented without any benefits for the business stakeholders are commonplace. In contrast, cloud computing offers business users the chance to immediately implement services with usage-based billing that are tailored to their requirements, often without the need to consult with the ITdepartment. However, aspects like security, architecture, availability, and standards are often not evaluated. Cloud consumers find themselves at the mercy of the cloud provider. Scenarios that require changing cloud providersafter a cloud provider goes bankrupt, and the associated moving of data and/or applications, have not yet been sufficiently tested. Business continuity should play a key role from the start of a cloud evaluation process. One of the greatest challenges here is the integration of existing data and systems into the cloud solution. Without integration spanning between clouds and on-premise systems, processes can only be executed inisolation, leading to cloud-specific silos of isolated solutions. Important information for users is not available across processes and systems. Problems that would have occurred in the company’s internal IT are nowshifted to the cloud provider. To prevent “legacy clouds” or solutions that are hard to maintain, it is important to manage the entire architecture proactively and, in particular, the integration into the cloud. Even if cloudproviders want us to believe otherwise, not every aspect of IT can be outsourced to cloud solutions!  Read the paper here.

  • Cloud Computing Definition & Architecture for Cloud Service Brokers

    Juergen1Cloud Computing Hype Introduction

    Why is everyone talking about cloud computing? Drawn-out, expensive IT projects that are planned and implemented with few benefits for the business stakeholders are commonplace. In contrast, cloud computing offers business users the chance to immediately implement services with usage-based billing that are tailored to their requirements, often without the need to consult with the IT department.

    However, aspects including security, architecture, availability, and standards are often not evaluated. Cloud consumers find themselves at the mercy of the cloud provider. Scenarios that require changing cloud providers after a cloud provider goes bankrupt, and the associated moving of data and/or applications, have not yet been sufficiently tested. Business continuity should play a key role from the start of a cloud evaluation process.

    One of the greatest challenges here is the integration of existing data and systems into the cloud solution. Without integration spanning clouds and on premise systems, processes can only be executed in isolation, leading to cloud-specific silos of isolated solutions. Important information for users is not available across processes and systems. Problems that would have occurred in the company's internal IT are now shifted to the cloud provider. To prevent "legacy clouds" or solutions that are hard to maintain, it is important to manage the entire architecture proactively and, in particular, the integration into the cloud. Even if cloud providers want us to believe otherwise, not every aspect of IT can be outsourced to cloud solutions!

    In the SOA Magazine III “Cloud Computing Definition & Architecture for Cloud Service Brokers” we introduced the cloud computing definition, concepts and the idea of Cloud Service Broker. In this article we discuss the Cloud Service Brokers in details including their roles, services, market opportunity and challenges.

     

    Cloud service broker definition

    The paper “Defining Cloud Services Brokerage: Taking Intermediation to the Next Level” written by Daryl C. Plummer, Benoit J. Lheureux, Frances Karamouzis and published by Gartner in October 2010, defines cloud services brokerage (CSB) as "A cloud services brokerage is a business model in which a company or other entity adds value to one or more (generally public or hybrid, but possibly private) cloud services on behalf of one or more consumers of those services." The authors do not define cloud brokers in categories like the NIST definition in 2011 (Service Intermediation & Service Aggregation & Service Arbitration). Instead the paper highlights the types of CSBs by backup & recovery, integration, customer development, governance or service marketplace. In recent papers Gartner follows the NIST cloud broker categories.

     

  • Introducing the Integration Cloud Service

    ics18by Robert van Mölken published inSOA Magazine V

    Oracle released some more Cloud offerings and in this article we introduce the Integration Cloud Service. This cloud service lets your organization create integrations between cloud applications, but also between cloud and on premise applications. Create connections to well-known and less known SaaS applications using a bunch of cloud adapters, publish or subscribe to the Messaging Cloud Service, or use industry standards like SOAP & REST. The available set of cloud adapters will certainly grow in the future when the marketplace is fully up-and-running.

    Why should organizations consider the Cloud?
    Let's get started with the key benefits and features before diving into them more detailed. Why should organizations consider the Cloud?

  • Java Cloud Service - initial impressions for WebLogic architects and administrators

    jcs3by Simon Haslampublished inSOA Magazine V

    There's no doubt that "the cloud" is coming, even in the relatively conservative world of mission-critical Oracle platforms.

    At the end of 2012 I took a trial of what was then "Java (or WebLogic) as a Service" (now known as "SaaS Extension"). Back then I wasn't hugely impressed - yes, I could deploy a simple web app, but the WebLogic environment was very heavily constrained and almost entirely hidden from the administrator - no WebLogic console, no WLST, minimal logs. As a result as soon as I tried to deploy something non-trivial, in this case Apache Roller (the software running this blog), I ran into all sorts of class white-list issues and with little debug information so I quickly gave up in despair!

  • Process Cloud, a game changer in process implementations

    pcs3by Léon Smiers and Jeroen van Essen published inSOA Magazine V

    Oracle is accelerating the delivery of all of its Software as a Service (SaaS) solutions and Platform as a Service (PaaS) solutions to gain market share in the cloud space. The Oracle Process Cloud Services (PCS), a Paas Solution, is one of the new services that is delivered now in controlled availability to a selected set of customers, and will be general available in the near future. With this service we are entering a new era for development and management of processes with Oracle technology. The cloud based delivery and management model of the processes is aimed at simplification and improvement of time-to-market. 

    PCS builds on top of the already existing Oracle BPM technology. The delivery of functionality towards the cloud will be gradually extended in the coming releases. We see this product as a potential game-changer in the market, because of the simplicity and possible mash-up scenarios with other Oracle PaaS offerings and on-premise applications.

    In this article we will have a quick glance at what the Process Cloud offers, look at typical use cases and see the look-and-feel of development.

  • SOA and Cloud - Where's This Relationship Going - Industrial SOA?

     

    Release: OTN 6.2014
    Authors: Jürgen Kress, Hajo Normann, Guido Schmutz

    Opinions vary on the relationship between service oriented architecture and cloud computing. Some say SOA is essential to the cloud. Others say cloud is entirely possible without SOA. In this three-part program three members of the Masons of SOA, the group behind the Industrial SOA article series, offer their insight into the issue.
