Which type of service would you use for real-time data updates in Informatica Cloud?

Using Data Synchronization in Informatica Cloud is the appropriate choice for real-time data updates because it is specifically designed to handle the continuous flow of data between systems. This service enables you to synchronize data in near real-time, ensuring that any changes made in one system are promptly reflected in another. This is particularly useful in environments where timely data availability is crucial, such as in customer relationship management or e-commerce applications.

The other services do not focus on real-time updates. Batch processing, for instance, typically involves processing large volumes of data at scheduled intervals rather than in real-time. Data Replication might involve creating offline copies of data at regular intervals but is not geared towards immediate synchronization. Data Warehousing, on the other hand, refers to a data management system optimized for query and analysis rather than for real-time data updates. Thus, Data Synchronization stands out as the best service for achieving real-time data connectivity and updates.
