SOAP vs REST

SOAP :

  • It stands for Simple Object Access Protocol.

  • It is a protocol which follows a strict standards to allow communication between the server and the client.

  • It uses only XML for making requests and receiving responses which can increase it's complexity. Sometimes , there is a need to build those requests manually, which increases the chances of error.

  • It has built-in error handling which means it provides the information about the error in requests and responses which you can fix. It provides end-to-end reliability even through SOAP intermediaries

  • It requires high bandwidth for its usage. As request or response contains a lot of information inside of it, the amount of data transfer using SOAP is generally a lot.

  • It uses @WebService and it ensures ACID compliance transaction.

  • It provides pre-build extensibility in the form of the WS* standards and it also has SSL( Secure Socket Layer) and WS-security.

  • It works well in distributed enterprise environments.

  • It is more secure and used in the cases like Bank Account Password, Card Number, etc.

  • It provided more enterprise-level security features if you require them.

  • It supports HEAD, OPTIONS, TRACE and PATCH requests as well.

REST :

  • It stands for Representational State Transfer.

  • It is an architectural pattern which doesn't follow any strict standards but has some constraints to allow communication between the server and the client.

  • It is not restricted to XML only for making requests and receiving responses which makes it less complex. it supports the OpenAPI, Swagger and RAML formats.

  • REST HTTP requests are: POST, GET, PUT, and DELETE.


GET
Read or retrieve data
http://localhost:<PORT>/employee/id

POST
Add new data
http://localhost:<PORT>/employee/create

PUT
Update data that already exists
http://localhost:<PORT>/employee/patchFields

DELETE
Remove data
http://localhost:<PORT>/employee/id

  • It takes fewer resources and bandwidth. As request or response uses multiple standards like HTTP, JSON, URL, and XML for data communication and transfer.

  • It uses uri like @Path.

  • It provides SSL and HTTPS for security.

  • It lacks ACID compliance transaction.

  • It is optimized for the web. Using JSON as its data format makes it compatible with browsers.

  • It is more efficient as it provides excellent performance and scalability.

  • It can make use of SOAP as the underlying protocol for web services as it is just an architectural pattern.

  • It is closer to other web technologies in designing.
