    SOA and service-orientation have laid the foundation for a variety of emergent service technology innovations such as cloud computing and Big Data, while the original building blocks of SOA and service-orientation (which include BI, BPM and MDM, among others) continue to evolve by embracing fundamental service technologies, concepts and practices. The models, principles and patterns behind SOA and service-orientation can be applied to formalize any of the environments produced by modern service technologies. For example, SOA can establish interoperability between different data sources to consolidate Big Data solutions via schema-based interfaces, even when canonical data models don't exist between the solutions' underlying data sources. For example, consider a US customer whose address and zip code are stored in a CRM system but has its state information stored in the data warehouse. An ontology established via a centralized service contract and implemented by a standardized service can establish the necessary link to provide the customer with a combined view. Similarly, service-orientation design principles can be applied to SaaS services that are deployed as part of cloud-based solutions. This application can help prevent cloud environments from accumulating disparate systems and services that will require subsequent integration in order to overcome the traditional problems associated with silos.While emphasis usually falls on the various methods of applying SOA and service-orientation to service technology products and platforms, it is advantageous to take a step back and discern the ways in which this evolving landscape can reciprocally help achieve the strategic goals of SOA. Never before has there been so much potential to realize service-orientation on.

    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.

  • Next Generation SOA

    NextGenerationSOAbookCoverRelease: The Prentice Hall Service Technology Series from Thomas Erl - October 2014

    Authors: Thomas Erl,Clive Gee,Jürgen Kress,Berthold Maier,Hajo Normann,Pethuru Raj,Leo Shuster,Bernd Trops,Clemens Utschig-Utschig,Philip Wik,Torsten Winterberg

    Innovative service technologies are becoming valuable assets for businesses that need to stay competitive in the face of increasing globalization and market complexity. While computer processing power is becoming faster and cheaper, search engines, instant messaging, and social media channels are generating floods of information that escalate demands for consumable and accessible data.

    As the world's economies engage one another through offshoring, outsourcing, and supply chaining, localization is required to accommodate different currencies and languages. Globalization, recession, invention, and communication are some of the driving forces behind a next generation of technologies and practices that revolve around software programs designed in accordance with the paradigm of service-orientation. Such programs, referred to as "services," are expected to do more for less with greater efficiency in order to meet business challenges head-on.

    We have reached a stage in the evolution of service-oriented computing where modern service technology innovation is building upon mature service platforms at the same time that proven delivery techniques and design patterns are building upon an established service-orientation paradigm. These developments have made it possible to create service-oriented solutions of unprecedented sophistication.

    Introduction
    Security requirements are usually relatively easy to manage when using local restrictions in conventional closed systems. They become more complex in the distributed system landscape of an SOA. Not limited to only an application or an application domain anymore, security must work across a range of applications and business processes. Numerous security standards have been created in order to realize these comprehensive security requirements. These include WS-SecurityPolicy, WS-Trust, XML Encryption, XKMS, XML Signature, WSFederation, WS-SecureConversation, SAML1, SAML2, and many more. Currently, no product or open source framework can fully support all of these standards. In our experience, incompatibilities arise whenever an SOA product or deployed Web service framework needs to communicate outside of its small ecosystem. Not surprisingly, project managers who are confronted with increasing expenses tend to start looking for viable alternatives. They then usually choose to develop inflexible solutions in-house that can quickly implement risky anti-patterns, such as transferring usernames and passwords within the functional payload. The variety of different standards makes it difficult to formulate a clear understanding of the available security standards and internal product dependencies, in light of the individual restrictions to designing a well-secured system. Our aim is to provide IT experts and SOA architects with tips on how to handle security responsibly, using tried and true best practices as a basis.

  • SOA and Business Processes: You Are the Process! Service Technology Magazine 1.2014

    Release: OTN & Service Technology Magazine 1.2014
    Authors: Jürgen Kress, Berthold Maier, Hajo Normann, Danilo Schmiedel, Guido Schmutz, Bernd Trops, Clemens Utschig-Utschig und Torsten Winterberg

    Business Process Management is a management discipline that thrives to improve process performance. If done right, BPM leads to appealing, user-friendly processes that provide information about productivity, that measure performance and that illustrate the potential for improvement while indicating the exact location in the overall process that potentially benefits from one of various process optimization strategies.

    To deal with the complexity of modeling a company’s business processes, business analysts proceed hierarchically and begin by describing a value chain (process level 0) through several levels of processes, until they reach a level on which they depict a detailed description of the activities of process participants. Figure 1 gives an overview of BPM with a figure for each modeling technology and the interaction with SOA services.

    We see that Business Process Management and SOA go hand in hand: SOA enables BPM..  Read the paper here

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

    Abstract: Any place, any time: the old promise from the dotcom age has never been more relevant. With the release of the iPhone, Apple set off a huge amount of hype. Many people now have a laptop with broadband Internet connection and/or WLAN or UMTS Internet access. Yet these devices are still too large, too awkward, and take too long to boot up to be usable at any time. On the other hand, almost everyone has a smartphone these days, making them more mobile than ever in today’s economy.
    Smartphones are enormously practical and are becoming more and more powerful. They are generally very easy to operate, can be used almost anywhere, and the mobile web is becoming both faster and cheaper. App stores are shooting up everywhere and new functions can be installed with a single click. As the saying has it: “There’s an app for everything.”
    The use of built-in sensors provides for entirely new possibilities such as Google Maps integration, locationbased services, augmented reality, etc. Built-in cameras are becoming more and more powerful and are often used as a second compact camera. Video telephony is becoming more common—not just on Skype, now longestablished, but also through Apple Facetime. The speed of innovation is tremendous.

  • SOA MythBusters Episode #2: “SOA & Web Service Technology”

    soamyth5by Roland Carrasco and Arturo Viveros published inSOA Magazine V

    Introduction

    So, do you work with Oracle SOA Suite?, that’s great because we also do, every single day since a long time ago. As Oracle professionals, we’ve seen the SOA stack grow, change, incorporating new products and technology with each version, from 10g to 12c.

    We’re Rolando Carrasco (Oracle ACE) and Arturo Viveros (Oracle ACE Associate), the SOA Myth Busters from Mexico, and as we go with this series we will put to the test a number of questions, myths and urban legends regarding both SOA & the Oracle SOA Platform in seek of finding out which myths are true and which are not.

    SOA & Web Service Technology

    It’s a secret to nobody that Service Oriented Architecture and Web Services go hand by hand. However, the relationship between these two is very often and very awfully misunderstood. Thus, there are plenty of myths and misconceptions surrounding this particular topic, which we will attempt to tackle and clarify within this episode.
