What are disadvantages/challenges in web services

Distributed transactions. If the environment requires distributed transactions with heterogeneous resources, it should be studied and tested with standard solutions based on BTP, WS-Transactions, and WS-Coordination.

Quality of Service (QoS). In case of a mission-critical solution, the service providers must examine the reliability and performance of the service in peak load and uncertain conditions for high availability. The exposed infrastructure must provide load balancing, and fail-over and fault tolerance, to resolve these scenarios.

Security. Web services are exposed to the public using http-based protocols. As Web services is publicly available, it must be implemented using authentication and authorization mechanisms and using SSL-enabling encryption of the messages for securing the usage. Adopting open security standards like SAML, XML Encryption, XML Signature, or XACML may be a solution.
