Unfortunately, using certain open source database software as part of an HA architecture can present significant challenges. Therefore, DBAs must take a piecemeal approach to achieve HA with PostgreSQL, bringing together open source extensions and tools from multiple sources. there cannot be high availability.

Depending on the configuration, one can tune a hardware RAID for either performance or redundancy. Now let’s stretch our imagination and consider a second method of high availability, ala Citus. The best way to describe the Citus way of doing things is to reflect how data is managed by a disk RAID array.

I’m personally interested in this topic since I am a professor who researches human-computer interaction, user experience design, and cognitive science , so AI voice interfaces are fascinating to me. I’ve recently been brainstorming ideas for how to design such a system and how to deal with the practical challenges of scaling and maintenance.

Understanding DBaaS DBaaS cloud services allow users to use databases without configuring physical hardware and infrastructure or installing software. This eliminates the need for complex or scripted backup procedures and designated backup windows.
