What is SOA architecture?
What is SOA, or service-oriented architecture? SOA, or service-oriented architecture, defines a way to make software components reusable and interoperable via service interfaces. Services use common interface standards and an architectural pattern so they can be rapidly incorporated into new applications.
What are the characteristics of a SOA service?
It is self-contained. A service in SOA may depend on other SOA services. Consumers do not have any knowledge of what’s happening in the process. It is typically wrapped so as to represent a business activity. Web services promote an associate degree atmosphere for systems that are loosely coupled and practical.
What are the benefits of SOA?
In addition, the client -- which can also be a service -- can communicate with other services, even when they are not related. SOA benefits organizations by creating interoperability between apps and services.

Major objectives of SOA
There are three major objectives of SOA; each objective focuses on a different part of the application lifecycle.
Implementation
SOA is independent of vendors and technologies. This means a wide variety of products can be used to implement the architecture. The decision of what to use depends on the end goal of the system.
WS and WSDL models of SOA
Initially, SOA implementations were based on RPC and object-broker technologies available around 2000. Since then, two SOA models have been formed:
Benefits of Service-Oriented Architecture
SOA retains the procedure-call model commonly used in structured programming and standardizes the way in which business processes are automated and used, doing so in a way that maintains security and governance.
SOA disadvantages
The WS model of SOA has never been widely accepted or adopted, in part because of its inherent complexity, but also because of the incompatibility between the WS approach and the RESTful API model of the internet.
SOA and microservices
REST and the internet supplanted SOA before it really gained significant traction, confining SOA to legacy applications, often built around the ESB.

What is SOA protocol stack?
Here lies the protocol stack of SOA showing each protocol along with their relationship among each protocol. These components are often programmed to comply with SCA (Service Component Architecture), a language that has broader but not universal industry support. These components are written in BPEL (Business Process Execution Languages), Java, C#, XML etc and can apply to C++ or FORTRAN or other modern multi-purpose languages such as Python, PP or Ruby. With this, SOA has extended the life of many all-time famous applications.
Is SOA a success?
Though SOA enjoyed lots achieving the success in the past, the introduction to cloud technology with SOA, renewed the value of SOA.
What is SOA based on?
Contemporary SOA is based on open standards. Perhaps the most significant characteristic of Web services is the fact that data exchange is governed by open standards. After a message is sent from one Web service to another it travels via a set of protocols that is globally standardized and accepted.
What does SOA mean in architecture?
Perhaps the best way to view it is that if a product, design, or technology is prefixed with "SOA," it is something that was (directly or indirectly) created in support of an architecture based on service-orientation principles. Along those same lines, this book, though partially titled "Service-Oriented Architecture," goes well beyond architectural boundaries to explore the contemporary service-oriented platform.
