The Web

With the widespread use of the Web, distributed object technologies have been widely adopted to construct network-centric architectures, using XML, Web Services, CORBA, and DCOM. Organizations would like to take advantage of the Web in its various forms of Internet, Intranet and Extranets. This requires organizations to port and integrate their legacy assets to distributed Web-enabled environments, so that the functionality of existing legacy systems can be leveraged without having to rebuild these systems. In this chapter, we provide techniques to re-engineer standalone legacy systems into Web-enabled environments. Specifically, we aim for a framework that allows for the identification of reusable business logic entities in large legacy systems in the form of major legacy components, the migration of these procedural components to an object-oriented design, the specification of interfaces of these identified components, the automatic generation of CORBA wrappers to enable remote access, and finally, the seamless interoperation with Web services via HTTP based on the SOAP messaging mechanism.

The Way

In the last decade cloud computing transformed the way in which we build applications. The boom in cloud computing helped to develop new software design and architecture. Helping the developers to focus more on the business logic than the infrastructure. FaaS (function as a service) compute model it gave developers to concentrate only on the application code and rest of the factors will be taken care by the cloud provider. Here we present a serverless architecture of a web application built using AWS services and provide detail analysis of lambda function and micro service software design implemented using these AWS services.

Mining Algorithms

In order to improve the efficiency of service discovery and service composition, this paper proposes a Composition oriented Web services semantic relationships mining framework. Firstly, Web services need to be pretreated, which are filtered based on QoS; and then adopt the method of service functional clustering to generate service classes, which largely reduces the services search space and improve the efficiency of service discovery; Secondly, in order to excavate the semantic relationships between service classes that meet the business logic requirement, we need to set the composition rules between service classes; Finally, using two stages of mining algorithms to excavate the semantic relationships between service classes. Experimental results are given to validate the feasibility and validity of our framework.

Oriented Approach ◽  
The Web

This paper discusses Aspect-Oriented Programming (AOP) as an efficient way to handle security concerns in Web services. Without AOP, the necessary security code would be mixed with the business logic that a Web service implements. This renders the maintenance of both code and business logic tedious and prone to errors. AOP allows confining codes of non-functional concerns like security and self-healing into specific modules so that they do not cross-cut with the Web service's business logic. The proposed aspect-oriented approach in this paper is built upon three levels referred to as user, component, and resource, and adopts three types of context, one context per level. The contexts contain various details on the environment of Web services, which permits activating the necessary aspects in response to these details. A set of experiments validating this approach are also reported in this paper.

Open Issues

Several open issues in Web services architecture are being solved by using different kinds of solutions. Standard high-availability techniques based on the use of Web servers, business-logic-based caching systems, dynamic binding of Web services by programming the access to a SOAP message content from the business logic layer, and other kinds of current open problems can now be handled using a common unique technique. What we propose is to apply virtualization techniques to Web services.

Service-oriented architecture (SOA) is a mechanism for achieving interoperability between heterogeneous systems. SOA enables existing legacy systems to expose their functionality as services, without making significant changes to the legacy systems. Migration towards a service-oriented approach (SOA) not only standardizes interaction, but also allows for more flexibility in the existing process. Web services technology is an ideal technology choice for implementing a SOA. Web services can be implemented in any programming language. The functionality of Web services range from simple request-reply to full business process. These services can be newly developed applications or just wrapper program for existing business functions to be network-enabled. The strategy is to form a framework to integrate z/OS assets in distributed environment using SOA approach, to enable optimal business agility and flexibility. Mainframe applications run the business and contain critical business logic that is unique, difficult, and costly to replicate. Enabling existing applications allows reusing critical business assets and leveraging the assets as a service to be invoked in heterogeneous environment.
