AmberPoint’s application is used to pomp screen the performance of SOA-driven applications and aid clients remedy complications. it is “totally complementary” to Oracle’s own SOA software and should “allow accelerated control and efficiency of essential functions throughout the enterprise,” in accordance with an FAQ doc Oracle released Monday.


It is not clear how the deal will absorb an upshot on street maps for AmberPoint’s products. A evaluation is under manner and greater particulars can be forthcoming, Oracle referred to. funding in the products is expected to boost, in accordance with the FAQ.


“AmberPoint became considered one of a dwindling community of still-standing independents offering runtime governance for SOA environments,” analyst Tony Baer spoke of on the OnStrategies perspective blog.


The Move “patches some gaps in its commercial enterprise supervisor providing, not best in SOA runtime governance, but additionally with enterprise transaction administration – and doubtlessly – more desirable visibility to non-Oracle systems,” he introduced.


The deal is anticipated to shut within the first half of this year.

Service-Oriented Architecture and Legacy Systems | killexams.com real questions and Pass4sure dumps

This article first appeared in IEEE Software magazine. IEEE Software offers solid, peer-reviewed information about today's strategic technology issues. To meet the challenges of running reliable, resilient enterprises, IT managers and technical leads reckon on IT Pro for state-of-the-art solutions.

Enterprise systems are quickly evolving from monolithic silos to distributed applications with service-oriented exible usage schemes. To withhold up, IT organizations must fit their legacy systems to meet changing business challenges almost in real time, with no second chances. Service-oriented architectures (SOAs) absorb evolved to exibly operate and federate business processes and underlying systems. Authors Nicolas Serrano, Josune Hernantes, and Gorka Gallardo provide an overview of current SOA technologies and how to evolve in legacy environments. I glance forward to hearing from both readers and prospective column authors about this column and the technologies you want to know more about. — Christof Ebert

Today’s business must be able to flexibly and quickly fit to market needs, but even minor changes to processes can involve rework in multiple IT systems that were originally designed as application silos. To abide competitive, maintenance efforts must be reduced, yet IT systems must continue to evolve. Service-oriented architecture (SOA) enables the transition from a silo-based system to a service-oriented one. It facilitates slack coupling, abstraction of underlying logic, fl exibility, reusability, and discoverability. 1,2 The SOA Manifesto outlines additional guiding principles.

SOA Primer SOA’s novelty is in how it designs infrastructure architecture based on services instead of focusing on entire applications. Services are small, discrete units of software that provide a specific functionality and can be reused in multiple applications. SOA applies a loose-coupling design principle, which means that each service is an isolated entity with limited dependencies on other shared resources such as databases, legacy applications, or APIs. It helps provide an abstraction layer between producers and consumers, which promotes fl exibility in changing service implementations without impacting consumers. SOA offers several benefi ts to busi- nesses, but it isn’t the best architectural option for everything cases. On the plus side, it:

  • provides a natural route to modularize complicated systems by integrating services from different vendors independent of platform and technology;
  • promotes slack coupling, helping the interface with legacy systems;
  • increases efficiency by allowing applications to be reused, thus reducing cost and progress time;
  • improves flexibility and scalability because multiple services can be easily developed from the integration of existing applications;
  • allows a reduction of costs associated with maintenance;
  • enables standards-based interoperability between systems;
  • provides location independence to access data via any channel such as smartphones, tablets, or laptops; and
  • allows an incremental approach to be taken, which helps meet customer demands faster by adding new services in response to specific business needs. However, on the minus side, it
  • is difficult to implement asynchronous communication between applications;
  • is challenging to implement real-time responses or lofty data transfers because XML brings robustness, not quicken (although there are other alternatives such as JSON);
  • has numerous security vulnerabilities due to process-sharing applications and systems; and
  • involves complicated transaction management in interactions between logically divide systems.
  • Moving to SOA isn’t easy, and enterprises wishing to accomplish so must be awake of the difficulties and inherent issues. Needless to say, every IT organization will sustain multiple tradeoffs with SOA implementations; your mileage may vary. For effi ciency and fl exibility they recommend an incremental transition to SOA in legacy environments.

    Web Services

    Web services are, for most organizations, the simplest approach for implementing a loosely coupled architecture. This interoperability is gained through a set of XML-based open standards such as WSDL, SOAP, and UDDI to provide a common approach for defi ning, publishing, and using Web services .

    Web services evolved from Web applications. In fact, they’re a simplification of Web applications: in- stead of serving the user interface along with the data, they only serve the data; the client application is in freight of presenting the information. Consequently, Web services are the most common route to implement a SOA—indeed, many systems employ Web services without defining them as a SOA.

    The main edge of SOA (and therefore of Web services) is that the selfsame service can be consumed by different clients. The data that was originally designed for a Web application to consume can be used, without any modifi cation, by any other nature of client. Examples include desktop applications that glean data from a server without providing specific SQL queries of the database or external systems such as a vending or public client information point that gets its data from a SOA service.

    A legacy system can be wrapped as a SOA service and respond directly to the HTTP protocol or drudgery behind a proxy that translates the request to the legacy system’s language. Ultimately, the message in HTTP is plaintext, which any system or programming language can produce.


    SOA is a helpful option for pile more fl exible applications, but choosing the perquisite technology to achieve it will depend on your needs and environment. Let’s review the most germane technology considerations for organizations wishing to adopt SOA in their own business processes.

    SOAP vs. REST

    When designing a Web service, they requisite to define the set of rules we’re going to employ to exchange information. The main tools for doing this today are SOAP and REST. 3 SOAP is the older protocol; it was developed as an Internet-capable alternative to established technologies such as CORBA. SOAP can employ various transports (HTTP, SMTP, and so on), which gives it more fl exibility. Data is exchanged in XML, so some performance issues could arise if the amount of information or messages transferred is high. SOAP can be used with Web Services Security, a measure for signing and encrypting messages that offers more secure information exchange. 4

    REST is a newer protocol that uses HTTP transport, but it can wield several data formats (XML, JSON, and so on); it relies on a specific URL instead of XML. comfort is a lightweight alternative to SOAP. Because it doesn’t impose a rigid implementation, it has a higher degree of fl exibility, is lighter, and is less contingent on documentation. As comfort can employ glean methods, as opposed to the POST-only SOAP implementation, caching can befall not only in the service’s design but moreover on the infrastructure side.

    Choosing comfort or SOAP will depend on an organization’s needs and constraints. Sometimes, you’re better off with the enterprise capabilities that SOAP offers, or maybe you would benefi t from a more performant and lightweight alternative such as REST. Because SOAP has better security and error-handling capabilities, most enterprise IT shops regard it as their preferred Web service implementation. Simplicity, performance, and a less rigid implementation everything Make comfort the preferred implementation for those working on the collaboration APIs create in Internet services (see the sidebar for an example).

    Legacy Modernization

    Although SOA architecture can be the best alternative for seamlessly integrating enterprise systems and avoiding the headaches of protocols 5 and platforms, most people requisite to deal with an existing infrastructure. There’s no flawless solution to the problem of modernizing legacy systems as you try to adopt a SOA architecture because a variety of aspects arrive into play. You requisite to Take into consideration the current technological stack to Make the optimal transition based on overall cost and risk.

    Because legacy systems usually champion key business processes, a step-by-step change design should be developed and a feasible evolution of the current systems using a hybrid approach should be designed to achieve a absolute SOA architecture. There are several strategies for converting legacy systems to SOA.

    The first approach is to replace the current legacy system with another system or set of systems. Normally, this is a helpful route to fade if a current commercial off-the-shelf system (COTS) option matches the legacy system’s requirements and functionalities. This solution reduces maintenance but increases costs in future modifications. A second alternative is to wrap the current legacy system with a middleware that can offer the legacy system interface through a Web service. In this way, legacy functionality is “wrapped” with a service layer and “plugged” into a SOA environment. This might not solve some of your problems: the legacy application can integrate several possible services, and you won’t glean the expected decoupling. However, it’s a helpful option when the legacy system is expensive to rewrite, can be reused, and requires a cost-effective solution. Finally, the third alternative is to redevelop or recode the current legacy system. This can be a very helpful approach, as you can act on the application architecture and achieve the optimal levels of decoupling. However, legacy applications are normally critical, and they’re sometimes difficult or expensive to change due to the obsolete technologies involved and the want of documentation, which could lead to some problems and expand the project risk. In this case, correctly assessing everything the involved risks is a must.

    Enterprise Application Integration

    When planning for application integration in any SOA initiative, many vendor products can befriend you ease into the transition. However, the different offerings gain in capability and complexity, so selecting the perquisite one is vital for success. You can divide the alternatives into three different groups based on the level of integration complexity (See device 1):

  • Integration frameworks are the lightest of the alternatives and are basically formed by the libraries that implement APIs for   different progress environments. Examples of these integration frameworks are Apache Camel and Spring Integration in the Java environment and NServiceBus for .NET.
  • Enterprise Service Bus (ESB) products offer integration framework capabilities plus tools for deployment, administration, and monitoring at runtime. ESB supports the connections between service producers and consumers, thereby offering the edge of better tooling, which reduces cost and complexity signifi cantly and solves integration problems at a higher abstraction level. Exam- ples of ESB products are Oracle Service Bus and Mule ESB.
  • Integration suites offer a com- plete stack that not only gives ESB capabilities but moreover more   business-specific tools such as BPM (business process management), business activity monitoring, master data management, and a repository. everything of these features befriend you respond to changes more quickly.   It’s difficult to understand how competing solutions stack up against one another, so Table 1 compares these three integration solutions.
  • Making Choices

    Obviously, the best alternative depends on specific needs and complexity. First, you must settle whether a framework is suffi cient. For instance, if you absorb only two applications to connect or you can drudgery with a single technology (such as REST), you might opt for the simplest approach (integration framework) in spite of the scarcity of tools and support; otherwise, an ESB is the better choice. However, if additional features are required, you might be better off with a more capable and complicated stack such as an integration suite. 

    The next evolutionary step forward will be how to Make the convergence of SOA and cloud computing easier. The ascend of the cloud has brought advantages to enterprise: cloud computing provides resources you can leverage on demand, including those that host data, services, and processes. You can extend your SOA outside of the enterprise firewall to cloud computing providers.

    Thus, cloud integration is one of the main challenges enterprises are dealing with today. In this context, iPaaS (integration platform as a service) is emerging as a suitable option  for a wide gain of integration needs. iPaaS is a suite of cloud services that enable users to create, manage, and govern integration flows connecting a wide gain of applications or data sources without installing or managing any hardware or middleware.

    Looking to the future, research hard Gartner predicts that by 2016, at least 35 percent of everything large and midsize organizations worldwide will be using one or more iPaaS offerings in some form. However, experts opine that iPaaS won’t replace SOA: traditional SOA will still be required for complicated integration scenarios such as low-latency messaging and dataintensive transactions within and between enterprises.

    Robert Stackowiak

    Robert Stackowiak

    Robert Stackowiak and Rick Greenwald are super busy. They both wield a lot of responsibilities in their “day” jobs at Oracle. They moreover managed to squeeze in enough time to complete the latest update to their book, Oracle Essentials. It is currently available here as an early release. Both Robert and Rick took some time out to respond a few questions about the book, how they started working with Oracle, and writing. I’ve focused on Robert for this post but abide tuned for a later post that provides some behind the scenes insight from Rick Greenwald.

    How did you glean started working with Oracle technologies? How long absorb you been working with them?

    Robert Stackowiak: I started working with the Oracle Database while at the U.S. Army Corps of Engineers in St. Paul in about 1984. The St. Paul District was one of the first Corps Districts to employ the Oracle Database to write applications.

    What is your day-to-day job with data entail?

    Robert Stackowiak: I befriend lead Oracle’s sales and architecture teams and Oracle’s customers in defining and pile information architectures. This includes everything aspects including databases, mammoth Data solutions, business intelligence and data discovery tools, and integration tools and strategies.

    Is there a particular feature of Oracle 12c that you account will be particularly useful to those working with data?

    Robert Stackowiak: The features generating the most buzz (that I am positive Rick will talk about) are Pluggable Databases and heat maps. In the analytics area, I account that pattern matching could draw quite a bit of interest where organizations are looking for Map Reduce-like capabilities to be used in making sense of data stored in Oracle.

    Any counsel for someone who is looking to equilibrium working and writing?

    Robert Stackowiak: Most of my writing takes residence on weekends and long plane rides. A lot of my writing helps me better articulate how Oracle’s products work, so writing helps me a lot in my day job.

    Who is the audience for the book?

    Robert Stackowiak: This bespeak is about concepts and fundamentals Important to understanding how the Oracle Database works. Those that most esteem the bespeak are often new to Oracle or want a concise overview of what Oracle is about in a single volume. The bespeak is not for those who want a particular how-to description of one specific aspect of Oracle – the Oracle documents and other more targeted books cover that.

    What accomplish you hope the reader will learn after reading the book?

    Robert Stackowiak: They should gain an understanding as to the scope of capabilities provided by the Oracle Database. They should moreover originate to understand where they might requisite to accomplish further exploration.

    When did you first start writing? How did that arrive about?

    Robert Stackowiak: My first professional journal article discussed the value of networked computers to civil engineering solutions and was written in 1986. The Corps of Engineers was an early agency to explore using Unix servers for email and applications. I began to write articles for a variety of technical journals shortly thereafter. Oracle Essentials was my first bespeak and led to many others.
