Links of the day 08/07/2015: Storage tipping point, SSL, reverse proxy, #Container with the virtualization goodies on top ( or under )

  • The Storage Tipping Point -- the performance optimization technologies of the last decade – log structured file systems, coalesced writes, out-of-place updates and, soon, byte-addressable NVRAM – are conflicting with similar-but-different techniques used in SSDs and arrays. The software we use is written for dumb storage; we're getting smart storage; but smart+smart = fragmentation, write amplification, and over-consumption.
  • s2n -- Amazon's open source ssl implementation.
  • pushpin -- a reverse proxy server that makes it easy to implement WebSocket, HTTP streaming, and HTTP long-polling services. It communicates with backend web applications using regular, short-lived HTTP requests (GRIP protocol). This allows backend applications to be written in any language and use any webserver.
  • Hyper : Make VM run like Container. Fast as Container, Isolated by VM. Intersting approach, Upon the RUN command, Hyper launches a new VM instance, instead of containers, and mount the specified image onto the instance. Inside to the VM, a minimalist Linux kernel, called HyperKernel, is booted. HyperKernel is built with a tiny Init service, called HyperStart, which creates a Pod, setup Mountnamespace, and launch apps from the loaded image.
