An apples to apples comparison of the costs associated with running various usage patterns on-premises and with AWS requires more than a simple comparison of hardware expense versus always-on utility pricing for compute and storage. Total Cost of Ownership.
Also, in general terms, a high availability PostgreSQL solution must cover four key areas: Infrastructure: This is the physical or virtual hardware database systems rely on to run. Can you afford the necessary hardware, software, and operational costs of maintaining a PostgreSQL HA solution? there cannot be high availability.
However, it’s important to note that the optimal value may vary depending on your specific workload and hardware configuration. In general, the recommended value for innodb_thread_concurrency on a server with 10 CPUs is typically between 16 and 32. 16) and monitoring the server’s performance.
Because recognizing if the workload is read intensive or write intensive will impact your hardware choices, database configuration as well as what techniques you can apply for performance optimization and scalability. While our whitepaper Performance at Scale could provide useful insight if you are at the planning or review stage.
In the European Commission’s whitepaper on artificial intelligence all three come together in an almost comical manner: the fear of a high-tech digital future; the need to protect oneself against it; and the complacency inherent in the belief that regulation is the solution. The dominant sentiment in modern-day Europe is anxiety.
In the simplest case, you have a growing workload, and you optimize it to run more efficiently so that you don’t need to buy or rent additional hardware, so your carbon footprint stays the same, but the carbon per transaction or operation is going down.
Failover ensures that if the primary MySQL server becomes unavailable due to hardware failure or another issue, the system seamlessly switches to a standby replica. To delve deeper into this topic and explore Percona’s recommendations for HA architecture and deployment, we invite you to download our whitepaper.

However, Ovais Tariq details a known bug ( or feature ) when using a setting of “0” So it is recommended to set it to “ 1″ To change the swappiness value: # Non persistent - the value will change to the previous value if you reboot the OS echo 1 > /proc/sys/vm/swappiness And to persist it across reboots: # Change in sysctl.conf (..)
I became the Sun UK local specialist in performance and hardware, and as Sun transitioned from a desktop workstation company to sell high end multiprocessor servers I was helping customers find and fix scalability problems. We had specializations in hardware, operating systems, databases, graphics, etc.
