Service-oriented architectures (SOAs) have become popular these days due to their ability to promote business development. According to Microsoft, SOA is “a set of components which can be invoked, and whose interface descriptions can be published and discovered”. With this, SOA is capable of performing various tasks for productivity and efficiency.
Here are the features of SOA with its corresponding benefits and supporting infrastructure:
Service is the original concept of SOA. It improves information flow and organizational flexibility. It can provide freer information flow within and between systems. Organizing internal software as services can make it easier to determine its functionality which would lead to increased visibility to its customers.
SOA allows software services to invoke each other directly through various systems like programming-language function calls. Services can connect with each other by exchanging messages. Consistent use of messaging provides a benefit in which services can be easily moved between computer systems within enterprises.
Message monitoring streams between business actions and analyzes them to get information about those activities. This feature can also provide security attack detection which includes recognition of denial-of-service attacks.
This feature can provide application of management policy and security policy. Through this, SOA can give priority to certain kinds of messages. Also, it can control access to messages that could damage the enterprise systems.
Message transformation focuses on data translation in which it will convert the data from one setup to another through automated field mapping. A specially-designed software can be very expensive, so it is advisable to use generic data translators.
Message security includes data confidentiality through encryption of information and data integrity which involves the addition of cryptographic integrity-check fields. Security is very crucial to enterprises, thus systems should have integrity checking.
Complex Event Processing
Through this, an enterprise system has the ability to adapt quickly to different external environments. In SOA, Complex Event Processing is linked with business activity monitoring. This includes detection of particular patterns in messages that could provide advance warning for various processes. For example, in banking, the detection of patterns may indicate fraudulent activities. Further, CEP provides simplification of software structure by removing functionality that is not contributory to business functions.
Service Composition refers to putting up various simple services to create a more complex one. It is the ability to develop new functionalities. For example, product sales websites use simpler systems such as product selection and payment method selection, however, if the service decides to create a much more convenient method of payment, they can develop a new internet cash payment method. Service composition can be done in two styles – orchestration and choreography.
Virtualization enables programs to be multi-functional by utilizing another asset to perform the function of a particular asset. Through this, a system can improve reliability and productivity as assets can perform similar functions in times an asset fails to perform well.
These are few of the many features of an SOA. Some others include Service Discovery, Asset Wrapping, and Model Drive Implementation. If you want to know more about SOA’s features, check out this article.
