But managing the deployment, modification, networking, and scaling of multiple containers can quickly outstrip the capabilities of development and operations teams. Docker Swarm First introduced in 2014 by Docker, Docker Swarm is an orchestration engine that popularized the use of containers with developers.

Dynatrace IT itself has implemented a NoOps model for our own IT operations. With a skeleton staff of 7 on a on 24×7 schedule, we increased the number releases from 2 to 26 per year and reduced production bugs by 93% since 2014. Infrastructure as code is sometimes referred to as programmable or software-defined infrastructure.

Since Kubernetes emerged in 2014, it has become a popular solution for scaling, managing, and automating the deployments of containerized applications in distributed environments. This virtualization makes it possible to efficiently deploy and securely run a container independently of the hosting infrastructure. What is Kubernetes?

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. A video of the talk is on youtube : The slides are on slideshare : I love this talk as I get to share more about what the Performance and Operating Systems team at Netflix does, rather than just my work.

Nowadays, the source code to old operating systems can also be found online. And here's an excerpt from [Linux] today (include/linux/sched/loadavg.h): #define EXP_1 1884 /* 1/exp(5sec/1min) as fixed-point */ #define EXP_5 2014 /* 1/exp(5sec/5min) */ #define EXP_15 2037 /* 1/exp(5sec/15min) */. Why, exactly, did Linux do this?

The main improvement MSLs give is that a program data race will not corrupt the language’s own virtual machine (whereas in C++ a data race is currently all-bets-are-off undefined behavior). If we can get a 98% improvement and still have fully compatible interop with existing C++, that would be a holy grail worth serious investment.
