Hey, it's HighScalability time:

From Systems Performance: Enterprise and the Cloud.

• Quotable Quotes:
  • @shanselman: Wife: "How was your day?" Me: "I'm using Grunt to automate NuGet creation for AngularJS." Wife: "But will that scale?" Me: "Well played."
  • John Hagel: winners in the concentrating parts of the economy are increasingly determined by the ability to connect with, and build strong relationships with, the participants who are operating in fragmenting parts of the economy.
  • Jack Clark: This means that although Amazon still grew at a respectable rate, its actual revenues were clipped by the heightened competition. This is what happens when you sell goods with deflationary pricing, it seems.


• Taxi app Hailo on Scaling micro-services Architecture on AWS: Micro-services + Containers + Scheduling on AWS will be a dominant architecture pattern in the next few years.


• Netflix. Revisiting 1 Million Writes per second. How will Cassandra perform on AWS's new instance types? There's no big reveal so you'll have to decide for yourself. Good discussion on reddit and Hacker News.


• TrueTime in Google's Spanner was one of its most buzzworthy innovations. Who doesn't like atomic clocks as a way to time-stamp transactions anywhere in the world? What if you don't have spare atomic clocks? Hybrid Logical Clocks: HLC captures the causality relationship like LC, and enables easy identification of consistent snapshots in distributed systems. Dually, HLC can be used in lieu of PT clocks since it maintains its logical clock to be always close to the PT clock.


• Vertical integration for the win. Apple is building out their own CDN with many terabits of capacity. Capable of handling traffic bursts from software downloads. Or maybe something else? More from Dan Rayburn in Apple’s CDN Now Live: Has Paid Deals With ISPs, Massive Capacity In Place. 


• Clouds make a lot of money on their network pricing. Chris Swan explores this marketing magic in Cloud Price Wars – What about the network?: there haven’t been any major shifts in network pricing.


• Scaling with Microservices and Vertical Decomposition: The architecture of otto.de is based on the concept of vertical decomposition: the whole system is vertically split into several loosely coupled applications. Every “vertical” is responsible for a single business domain such as “Order”, “Search & Navigation”, “Product”, etc. It has its own presentation layer, persistence layer and a separate database. From the development perspective, every vertical is implemented by exactly one team and no code is shared between the different systems.
