My last talk for 2017 was at AWS re:Invent, on "How Netflix Tunes EC2 Instances for Performance," an updated version of my [2014] talk. Our team looks after the BaseAMI, kernel tuning, OS performance tools and profilers, and self-service tools like Vector. We help where we can. schedtool –B PID. Virtual Memory.

By 2017, open source projects like Open-Tracing and Open-Zipkin were mature enough for use in polyglot runtime environments at Netflix. Our engineering teams tuned their services for performance after factoring in increased resource utilization due to tracing.

2017: MongoDB goes public, trading as MDB. So if they can’t beat ‘em in the DBaaS space, they often feel like they have to join ‘em — to the tune of total stack sharing or some proprietary arrangement. Some might say this marked the beginning of MongoDB’s “cloud push” escalation.)

Since its introduction by AWS in 2014, AWS Lambda has revolutionized the compute space and boosted the entire serverless movement. since 2017, and many customers have used it with great success while we collected requirements for the next iteration of our Lambda extension. A look under the hood of AWS Lambda.

Aftermath I provided details to AWS and Canonical, and then moved onto the other performance issues as part of the migration. Later that year (2014), Anthony Liguori from AWS gave a [re:Invent talk] recommending users switch the clocksource to tsc to improve performance. At least AWS have now included it in their recommendations.

Both Xen and KVM have had many performance and security improvements, and workloads can now be tuned to run at almost bare metal speeds (say, a 3% loss or less). If that seems wildly unacceptable, note that you can tune overcommit on Linux to not do this, and behave more like Solaris (see sysctl vm.overcommit_memory).
