Fault tolerance allows a system to continue functioning, even with degraded performance, if portions of it fail or degrade, without the entire system or service being taken down. It can detect problems within a service and invoke compensating systems or functions to keep functionality going. Although redundancy is similar to fault tolerance, it is more focused on having additional copies of systems available, either active or passive, that can take up services if one system goes down. Elasticity pertains to the ability of a system to resize to meet demands, but it is not focused on system failures. Automation, and its role in maintaining large systems with minimal intervention, is not directly related to fault tolerance.

Representational State Transfer (REST) uses TLS for communication over secured channels. Although REST also supports SSL, at this point SSL has been phased out due to vulnerabilities and has been replaced by TLS.

Simple Object Access Protocol (SOAP) and Representational State Transfer (REST) are the most commonly used APIs within a cloud environment. Extensible Markup Language (XML) and Security Assertion Markup Language (SAML) are both standards for exchanging encoded data between two parties, with XML being for more general use and SAML focused on authentication and authorization data.
