Oracle SOA Tutorials
The intent of this tutorial is designed for software programmers who would like to understand the concepts of SOA. In these tutorials, you will study topics such as the installation of Oracle SOA 11g, configuring adapters, creating business rules, and SOA projects. We will also discuss in detail security in Oracle SOA 11g and different protocols that we use to connect to partner systems. This tutorial will give you enough understanding from where you can take yourself to higher levels of expertise.
Gologica’s Oracle SOA Online Training provides you an in-depth understanding of the Oracle SOA 11g suite and how to make use of a hot-pluggable and comprehensive software suite to manage, deploy, and develop Service-Oriented Architecture.
Introduction
Service-Oriented Architecture is an architectural format that consists of a collection of services in a network that communicates with each other. The complication of every service is no longer considerable compared to other service.SOA allows the integration of distinctive systems or technologies. The MetaData present in SOA is built upon XML, which helps in transporting the data through structuring it. The needs of the current world require complex IT landscapes with a variety of disparate systems, applications, and multiple platforms.
Integrating with cloud platforms, mobile-enabled the current applications, and starting developments on the latest trends through connecting the Internet of Things (IoT) devices to the existing infrastructure consists of the main focus of organizations. When organizations address each of these new integration challenges independently, using a framework of area of interest distinctiveness integration toolsets, the original goals of faster business integration, improved application infrastructure flexibility, and reduced prices are no longer achievable.The average development helps to orchestrate the services of diverse systems. This is where Oracle SOA comes in. It stands among the dominant middleware platforms in the market. It is the most popular platform for complex application integrations.
What is Oracle SOA?
Oracle SOA Suite allows the developers to build the services and control them. The services can then be utilized by the business processes and composite applications. Organizations can effortlessly extend and evolve the architectures with the hot-pluggable components from Oracle SOA Suite. Replacing current investments would no longer be required. The product strategy, product details, and customer experience referring to the SOA Suite are shared by Oracle Corporation.
Benefits are as follows:
- Reduce the time to market for new task integration, and efficaciously manage the technological modifications and business
- The improved visibility can be gained to react to business events
- Reduction in the integration cost and complexity
- Provide end-to-end solution monitoring with root cause analysis
- Ensure scalability and high availability for the enterprise infrastructure
Why SOA?
The IT companies were capable of facing the challenge of taking on an array of software systems that would possibly no longer be compatible. The IT organizations may even have to face the demands put ahead through a broad array of customers. Customers are accessing products and services via online interfaces and are a part of a supply chain where the cost and time of production need to be decreased.
This is why IT organizations are constantly looking for solutions to meet the demands. But, the technologies are surfacing only now, one of the major requirements to build a system is to have a standard for representing the software parts. Though SOA is not something absolutely new, there have been many standards set up through the Internet, like HTTP and HTML. Businesses that have witnessed the boom of the Internet are using similar principles to get the computer systems linked.
Advantages and Disadvantages of SOA
Advantages:
- Performance can be improved alongside the up-gradation of the system and the service functionalities.
- Applications can be developed except for the replacement of the current applications.
- Plugging in new services or enhancing the current services to place new business requirements.
- Reliable applications are furnished where independent services can be tested and debugged.
Disadvantages:
- High investment costs are required through SOA in terms of development, technology, and human resources.
- Greater overhead is provided when a service interacts with another. Machine load and response time are improved throughout the validation of input parameters.
- It is no longer available for applications with a GUI interface.
Why should you use Oracle SOA?
Re-use of Services Costs involved in testing and developments can be lowered by the use of existing software modules rather than writing new ones. This would ensure lower maintenance costs and better savings.
1. Messaging: The use of messaging would enable services to move between the computer systems inside the enterprise. The externally-provided services would be easy to use. The messages handled by the services can be changed to meet the new demands or the performance can be tuned.
2. Message Security: Message security involves data integrity by the addition of cryptographic integrity-check fields and data confidentiality by encryption of messages.
3. Complex Event Processing: Complex Event Processing offers benefits like:
Ability to adapt to the different scenarios: the focus needs to be put on the logic that connects the scenarios to the business events.
Simplification of the software architecture: removing functionalities from the business software services that are not related.
The improvement of security and management: security event detection and performance measurement are keys.
Latest Versions and Career Opportunities
The release of the Oracle SOA Suite 12c was announced in June 2014, which is the latest version at present. It promised simplified mobile, cloud, on-premises, and Internet of Things integration capabilities. The latest version accessible at existing is Oracle SOA Suite 12.2.1.3.0. The QuickStart version for the standard platform and the other systems intended for the cloud integrations are available as well.
Oracle SOA is being used by nearly 5000 companies across industries. It is being used by many developed foreign countries. So, having good knowledge and understanding of Oracle SOA could land you a handsome job. With the number of Oracle SOA developers being less, there is a higher market demand for the same and in turn a better pay. SOA is in-demand courses. There are no formal qualifications required to enroll for this course, but it is highly recommended that the participants have previous knowledge of XML, XSD, XSL, XSLT, XPath, and XQuery. Also, a clear understanding of WSDL files, SOAP, HTTP, SQL, and Java is recommended.
