Is the ACID property maintained when using microservices architecture?

In a microservices architecture, adherence to ACID properties (Atomicity, Consistency, Isolation, Durability) is usually not guaranteed as strictly across the entire system as it is in monolithic databases.

The reason is that microservices often use distributed databases and interact through network calls, which complicates the implementation of transactions that span multiple services.

Instead of traditional ACID transactions, patterns such as:

• Sagas — a sequence of local transactions with compensating actions in case of errors.
• Eventual Consistency — data in different services may be temporarily inconsistent but will eventually reach a consistent state.

Thus, microservices architecture is focused on ensuring high availability and scalability, sacrificing strict consistency in favor of more flexible consistency models.

If strict consistency is required, it is implemented within individual services, but not across the entire distributed system.
