One of the most important points about PostgreSQL on Ubuntu is that it is free. We do not have to worry about cost per core. It is a fully-featured database that supports a lot of features that modern applications need. In fact, it even supports document-based databases. It is quite a powerful solution. The performance of PostgreSQL on Ubuntu's parallel query executions was very good. That is why we selected the solution. We utilize ACID transactions with PostgreSQL on Ubuntu. ACID transactions impact our data reliability in our work significantly. Reliability is very important and ACID helps us reach that goal. Regarding isolation specifically, our application did not require any specific isolation of transactions, but overall, ACID is still very important.
