I am looking forward to share my thoughts on ‘Reinventing Performance Testing’ at the imPACt performance and capacity conference by CMG held on November 7-10, 2016 in La Jolla, CA. – Cloud. Cloud seriously impacts system architectures that has a lot of performance-related consequences. – Agile.

There were five trends and topics for 2021, Serverless First, Chaos Engineering, Wardley Mapping, Huge Hardware, Sustainability. I’d even use it to manage datacenter failover or failover for other cloud vendors, as what you really need is a highly available control plane that is totally independent of your own failure modes.

As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI. I happened to be speaking at a technical confering while still debugging this, and mentioned what I was working on to a processor engineer. We ended up setting it in the BaseAMI for all cloud services.

Linux has been adding tracing technologies over the years: kprobes (kernel dynamic tracing), uprobes (user-level dynamic tracing), tracepoints (static tracing), and perf_events (profiling and hardware counters). The way the cloud is used helps with security: most instances at my employer have only been up for one or two days.

There are three common mechanisms to access remote memory: modifying applications, modifying virtual memory, and hardware-level cache coherence support.
