SOAP and the Role of Website Performance Monitoring

The SOAP protocol utilizes a variety of different protocols and application layers in order to exchange information in web services. It can carry large loads of critical messaging and communication information that should be monitored. As a result, it makes sense to utilize website performance monitoring to track overall performance and identify any communication delay points.

What is SOAP?

SOAP (Simple Object Access Protocol) is a protocol specification for exchanging structured information when implementing web services in networks. It relies on XML (Extensible Markup Language) for its messaging, as well as RPC (Remote Procedure Call) and HTTP (Hypertext Transfer Protocol) for message transmission.

The XML-based protocol consisted of three parts: an envelope, encoding rules and a convention. The envelope defines the message and how to process it. The encoding rules are related to application-defined datatypes. The convention signifies procedure calls and responses.

The SOAP architecture consists of multiple layers for message format, Message Exchange Patterns (MEP), underlying transport protocol bindings, message processing models, and protocol extensibility. SOAP if often confused with SOA (Service-Oriented Architecture), however, they are very different from each other.

SOAP utilizes an internet application layer protocol as the messaging transport protocol. SMTP and HTTP are application-layer protocols used as the transport method for SOAP; however, HTTP is much more widely accepted. SOAP may also be used on HTTPS (an encrypted version of HTTP) by way of simple or mutual authentication.

How can Website Performance Monitoring Help?

Web service developers often need to see the SOAP messages used to call upon web services as well as the outcome of those messages. By utilizing website performance monitoring, developers can monitor SOAP messages in order to ensure systems are running properly.

There are many places within the SOAP protocol that can result in performance issues. Because the SOAP protocol utilizes a multi-step process to complete a messaging transaction, there are many different places for lags to take place. When website performance monitoring is implemented, these potential lag points can be identified and ultimately resolved by the developers working on the system. This can improve messaging and web service efficiency, keeping the overall system running properly.
