What is the difference between a REST and SOAP web service?

REST supports different formats like text, JSON and XML whereas SOAP supports only XML.

REST works only over HTTP(S) on a transport layer while SOAP can be used with different protocols on a transport layer.

REST works with resources, each unique URL is some representation of a resource while SOAP works with operations, which implements some business logic through different interfaces.

SOAP based reads cannot be cached, need to provide caching for SOAP while REST based reads can be cached.

SOAP supports SSL security and WS-security(Web Service-security) while REST only supports SSL security.

SOAP supports ACID (Atomicity, Consistency, Isolation, Durability) while REST supports transactions, but it is neither ACID compliant nor can provide two phase commit. .
