REST vs SOAP

Definitions

SOAP stands for Simple Object Access Protocol. SOAP is a standard web access protocol that has been employed a long time ago. SOAP is originally by Microsoft.

REST stands for Representational State Transfer. It was made to overcome the loopholes of SOAP. It generally assists SOAP and provides access to web services.

Both are web service communication protocols. SOAP has dominated the web services, but lately, REST has taken over space. About 70 pc public APIs employ REST as a protocol for data communication.

Primary Differences

REST operates through a confined and constant interface to access named resources. It is most commonly used when you are exposing a public API over the Internet. SOAP, on the contrary, exposes components of application logic as services rather than data. Moreover, it operates through multifarious interfaces. REST accesses data while SOAP performs operations through a more standardized set of messaging patterns. However, in most cases, either REST or SOAP could be used to achieve the same output, with some differences in how you configure it. SOAP was developed by Microsoft, and it is called a legacy protocol, whereas REST is relatively new in the world of API.

Merits of SOAP

Either protocol may be used to accomplish the majority of objectives. However, certain case studies indicate that SOAP is more appropriate. For example, if you need enhanced security, SOAP’s support for WS-Security may be helpful. It provides additional guarantees about the privacy and integrity of data. Additionally, it supports identity verification through intermediates, rather than simply point-to-point, as SSL does.

Additionally, SOAP has built-in retry logic to compensate for communication failures. Firewalls and proxies allow easy access to SOAP protocol as it uses HTTP protocol. SOAP is highly extensible through protocols. SOAP not only offers services for Web Services Security, but also for Web Services Addressing, Web Services Reliability Management, and Web Services Coordination.

Merits of REST

Apart from the obvious benefit of utilizing HTTP, REST provides many other advantages. REST supports a broader range of data types than SOAP, which is limited to XML. REST is usually regarded to be simpler to deal with than JSON. REST provides improved support for browser clients due to JSON. REST is a better performance framework. It is the protocol that is most often utilized by large services like Yahoo, eBay, Amazon, and even Google. REST is, on average, quicker.

Additionally, it is simpler to connect with pre-existing websites without requiring the configuration of infrastructure. This allows developers to work more efficiently rather than rebuilding a website from the ground up. Instead of all this, they may essentially add new features.

Similarities share by SOAP and REST

SOAP and REST have a lot in common with the HTTP protocol. SOAP, in comparison to REST, adheres to a more strict set of communications patterns. The SOAP rules are critical because, without them, no measure of uniformity is feasible. RESTful architecture is a type of architecture that does not need processing and is thus more flexible. Both SOAP and REST are regulated by well-defined rules.
