A RESTful API defines a set of functions that developers can use to perform requests and receive responses via HTTP protocol, such as GET and POST. Because RESTful APIs use HTTP as a transport, they can be used by practically any programming language and are easy to test. It’s a requirement of a RESTful API that the client and server are loosely coupled and independent of each other, allowing

We can create a controller object to handle the REST requests (GET, POST). In this controller we can use action routing [48] to control which function will handle which request. In every function, we can do some computations with the data, make decisions and use the HTTP web client to construct and send responses to the partner end point URLs.

Learned about different conventions to impart between the customer and servers and the techniques to be utilized as a part of correspondence such as doGet (),doPost (),doService () and so forth.

Discovers which options are supported by the AJP (Apache JServ Protocol) server by sending an OPTIONS request and lists potentially risky methods.

Microsoft’s internet information services (IIS) is one such solution. This webs server is designed to run on Windows server platforms. Consequently, it integrates well with Microsoft’s online applications. It features an intuitive graphical user interface that simplifies its installation and use. However, the costs of installing new versions of this web server are high. In addition, its restriction to the Microsoft server OS platform inhibits system flexibility. An alternative to IIS is the Apache web server. This is an open sourced application that can be implemented on a wide variety of operating system platforms. Apache’s integration of a pearl and PHP engine facilitates easy integration with the application programming interface (Gunther, 2006). In addition, this web server is available for free. This makes it a cost effective alternative. Further, Apache’s event-driven architecture enables it to perform ideally even under heavy loads. However, Apache usage involves a relatively strenuous learning curve. The software’s complexity may present an obstacle to its use by new users. Another web server that can be adopted for use in this project is Nginx. This server is easy to use as well as stable. It is also based on an event driven architecture. This architecture makes it an efficient user of system resources even under heavy loads (Tanenbaum, 2001). Nginx’s ease of installation, configuration, and use make it a viable alternative for adoption in

Know this acronym: API. It’s the technology that can transform your business into a platform.

Thus, the flexibility in SOA is made possible by loose coupling. However, optimization should be restricted to certain situations in SOA like when the Quality of Service (QoS) profiles are fixed and predetermined. Unfortunately, in the SOA environment optimization is an unfeasible expectation because of the dynamic environment of web services. Moreover, web service providers might not be willing to publish and create the profiles even though using QoS profiles are more reliable than other less-flexible optimization techniques. Thus, web services provide an organization with loosely coupled reusable software. Thus, this flexibility allows interoperability between systems to accomplish business functions. Further, business services can be completely allocated and decentralized over the Internet and collected by numerous communications

As design moves forward, the development teams begin to generate a tremendous amount of detailed information about the system. Modules, classes, data fields, data structures, forms, reports, methods, subroutines, and tables are all being defined in substantial detail in the design model. The key design tasks are decomposing the application into layers, clients, and servers, distributing the “pieces” across hardware platforms, and defining the physical network and protocols.

This is most likely why new web-oriented architecture (WOA) endeavours are seeing the light of day. Since they are littler, use Soothing abilities incorporated with HTTP, and can be empowered in existing web applications with minor changes.

The World Wide Web is established on numerous different technologies that make it possible for users to find and share data through the internet. For example there are Web browsers, HTTP (hypertext transfer protocol) and HTML (hypertext Markup language).

Cloud Computing and Web Services have become well known services that companies have been using. Web services provide the ways that organizations can use applications to communicate with each other across the internet. Cloud computing provides various types of service, such as software as a service, where a provider gives the company software that they can use for their business functions. While this may seem that both types of services are different from each other, they do share similarities that companies should take notice. Service oriented architecture has also started to become a useful feature that helps with integration in companies. One problem is that some companies have difficulty in implementing service oriented architecture, but cloud computing has started to become an option that has caused an impact in service oriented architecture and integration.

RESTful API service gathers pre-process data and generates REST APIs for EIS software service as seen in Figure 8. The RESTful API is also responsible for tasks such as load balancing, caching, access control, API metering, and monitoring, and can be implemented effectively using NodeJS express. The customer can easily and quickly develop an application, designing its data flow and web application using RESTful API.

(3) Web Services in the Cloud - instead of delivering full applications, this service allows users to access APIs for added functionality.

To move around the network securely and safely for organizations is very important. With the increase of this activity new security challenges came in existence. There are many malicious requesters who try to use organization’s web services by sending fake requests. So there is need to identify which request is sent by genuine requester and malicious requester. To avoid requests from fake requesters there is requirement of access control model that can store data about the person who made request for web service at the time of access request and utilize this data effectively in future while making access control decisions. This
