A distributed transaction enforces the ACID properties over multiple nodes, and might include systems such as databases, storage managers, file systems, messaging systems, and other data managers. In a distributed transaction there is typically an entity coordinating all the process to ensure that all parts of the transaction are applied to all relevant systems. Moreover, the integration of Storage as a Service (StaaS) within these environments is crucial, as it offers a virtually infinite pool of storage resources, accommodating a range of cloud-based data store classes with varying availability, scalability, and ACID properties. This integration is essential for achieving higher availability, lower response time, and cost efficiency in data-intensive applications deployed across cloud-based data stores.<ref>{{Cite journal |last1=Mansouri |first1=Yaser |last2=Toosi |first2=Adel Nadjaran |last3=Buyya |first3=Rajkumar |date=2017-12-11 |title=Data Storage Management in Cloud Environments: Taxonomy, Survey, and Future Directions |url=https://doi.org/10.1145/3136623 |journal=ACM Computing Surveys |volume=50 |issue=6 |pages=91:1–91:51 |doi=10.1145/3136623 |issn=0360-0300|url-access=subscription }}</ref>
