AI-powered optimization software provider Concertio today announced that it has raised $4.2 million, which it says it will use to scale its platform that boosts app performance by tailoring x86 server settings. Customers won't only benefit from faster, more stable apps and hardware as a result, says Concertio, but from lower infrastructure costs as well. Concertio's Optimizer Runtime tool, which runs on most CentOS and Debian Linux distributions running in the cloud or on-premises, monitors and learns from the interactions between apps and systems to tune parameters at each stage of development and deployment. An agent runs in the background and learns system metrics to detect different phases of execution, ingesting only a small sampling of data while dealing with system variability to optimize each phase separately. The Optimizer Runtime discovers hidden systems configurations that deliver optimal settings, and it optionally lets developers define optimization targets, including processor instructions, network bandwidth, database queries, and minimum server energy.
