Stuff The Internet Says On Scalability For March 6th, 2015

Hey, it's HighScalability time:


The future of technology in one simple graph (via swardley)
  • $50 billion: the worth of AWS (is it low?); 21 petabytes: size of the Internet Archive; 41 million: # of views of posts about a certain dress

  • Quotable Quotes:
    • @bpoetz: programming is awesome if you like feeling dumb and then eventually feeling less dumb but then feeling dumb about something else pretty soon
    • @Steve_Yegge: Saying you don't need debuggers because you have unit tests is like saying you don't need detectives because you have jails.
    • Nasser Manesh: “Some of the things we ran into are issues [with Docker] that developers won’t see on laptops. They only show up on real servers with real BIOSes, 12 disk drives, three NICs, etc., and then they start showing up in a real way. It took quite some time to find and work around these issues.”
    • Guerrilla Mantras Online: Best practices are an admission of failure.
    • Keine Kommentare: Using master-master for MySQL? To be frankly we need to get rid of that architecture. We are skipping the active-active setup and show why master-master even for failover reasons is the wrong decision.
    • Ed Felten: the NSA’s actions in the ‘90s to weaken exportable cryptography boomeranged on the agency, undermining the security of its own site twenty years later.
    • @trisha_gee: "Java is both viable and profitable for low latency" @giltene at #qconlondon
    • @michaelklishin: Saw Eric Brewer trending worldwide. Thought the CAP theorem finally went mainstream. Apparently some Canadian hockey player got traded.
    • @ThomasFrey: Mobile game revenues will grow 16.5% in 2015, to more than $3B
    • John Allspaw: #NoEstimates is an example of something that engineers seem to do a lot, communicating a concept by saying what it’s not.

  • Improved thread handling contention, NDB API receive processing, scans and PK lookups in the data nodes has lead to a monster 200M reads per second in MySQL Cluster 7.4. That's on an impressive hardware configuration to be sure, but it doesn't matter how mighty the hardware if your software can't drive it.

  • Have you heard of this before? LinkedIn shows how to use SDCH, an HTTP/1.1-compatible extension, which reduces the required bandwidth through the use of a dictionary shared between the client and the server, to achieve impressive results: When sdch and gzip are combined, we have seen additional compression as high as 81% on certain files when compared to gzip only. Average additional compression across our static content was about 24%. 

  • Double awesome description of How we [StackExchange] upgrade a live data center. It was an intricate multi-day highly choreographed dance. Toes were stepped on, but there was also great artistry. The result of the new beefier hardware: The decrease on question render times (from approx30-35ms to 10-15ms) is only part of the fun. Great comment thread on reddit.

  • A jaunty exploration of Microservices: What are They and Why Should You Care?  Indix is following Twitter and Netflix by tossing their monolith for microservices. The main idea: Microservices decouples your systems and gives more options and choices to evolve them independently.

  • Wired's new stack: WordPress, PHP, Stylus for CSS, jQuery, starting with React.js, JSON, Vagrant, Gulp for task automation, Git hooks, Lining, GitHub, Jenkins.

  • Have you ever wanted to search Hacker News? Algolia has created a great search engine for HN.

10 Reasons to Consider a Multi-Model Database

This is a guest post by Nikhil Palekar, Solutions Architect, FoundationDB.

The proliferation of NoSQL databases is a response to the needs of modern applications. Still, not all data can be shoehorned into a particular NoSQL model, which is why so many different database options exist in the market. As a result, organizations are now facing serious database bloat within their infrastructure.

But a new class of database engine recently has emerged that can address the business needs of each of those applications and use cases without also requiring the enterprise to maintain separate systems, software licenses, developers, and administrators.

These multi-model databases can provide a single back end that exposes multiple data models to the applications it supports. In that way, multi-model databases eliminate fragmentation and provide a consistent, well-understood backend that supports many different products and applications. The benefits to the organization are extensive, but some of the most significant benefits include:

1. Consolidation

Stuff The Internet Says On Scalability For February 27th, 2015

Hey, it's HighScalability time:


Hear ye puny mortal. 1.3 million Earths doth fill our Sun. Whence comes this monster black hole with a mass 12 billion times that of the Sun?

 

  • 1 Terabit of Data per Second: 5G; 1.9 Terabytes:  customer in stadium data usage during the Super Bowl; 1 TB: free each month on Big Query; 100x: reduced power consumption in radio chip

  • Quotable Quotes:
    • Robin Harris: But now that non-volatile memory technology - flash today, plus RRAM tomorrow - has been widely accepted, it is time to build systems that use flash directly instead of through our antique storage stacks. 
    • Sundar Pichai: That’s the essence of what we [Google] get excited about – working on problems for people at scale, which make a big difference in [people’s] lives. 
    • @timoreilly: Facebook is hacked 600,000 times a day. @futurecrimes First thing to do to protect yourself, turn on 2-factor authentication
    • @architectclippy: I see you have a poorly structured monolith. Would you like me to convert it into a poorly structured set of microservices?
    • Poppy Crum: Your brain wants as much as possible to come up with a robust actionable perception of the world and of the information and data that is coming in.
    • @BenedictEvans: Both Google and Facebook killing XMPP.  IM being euthanized just at the time messaging could become a third run-time for the internet
    • @dhh: 4-tier / micro-service architectures are organizational scaling patterns far more than they're tech. 1st rule of distributed systems: Don't.
    • @amcafee: Ex-Etsy seller: "In practical terms, scaling the handmade economy is an impossibility."
    • kurin: If you're behind a LB you can just drain the traffic to the hosts you're about to upgrade. Also, if you're above your SLA... I mean, some dropped queries aren't the end of the world.
    • @WSJ: Facebook’s 5,000+ staff generate $1.36 million each in annual revenue. The key to productivity is custom-built software tools
    • @jaykreps: Software is mostly human capital (in people's heads): losing the team is usually worse than losing the code.
    • Dylan Tweney: Mobile growth is huge, and could surge at least 3x in the next two years
    • Joe Davison: I learned that there is often more to business than meets the eye, and the only way to succeed is to plan ahead and anticipate all contingencies.
    • @etherealmind: Google published 30000 configuration changes to its network in 1 month 

  • What's different about AI this time around? Less hype, more data, more computation. The Believers: It was a stunning result. These neural nets were little different from what existed in the 1980s. This was simple supervised learning. It didn’t even require Hinton’s 2006 breakthrough. It just turned out that no other algorithm scaled up like these nets. "Retrospectively, it was a just a question of the amount of data and the amount of computations," Hinton says.

  • What lesson did Ozgun Erdogan learn while working on a database at Amazon that never saw the light of day? How to Build Your Distributed Database (1/2): This optimized plan has many computations pushed down in the query tree, and only collects a small amount of data. This enables scalability. Much more importantly, this logical plan formalizes how relational algebra operators scale in distributed systems, and why. That's one key takeaway I had from building a distributed database before. In the land of distributed systems, commutativity is king. Model your queries with respect to the king, and they will scale.

  • Replication for resiliency? Nature thought of that. Nibbled? No Problem: Champaign first observed in the 1980s, some plants respond by making more seeds, ultimately benefiting from injury in a phenomenon called overcompensation. More recently, Paige and postdoc Daniel Scholes suspected a role for endoreduplication, in which a cell makes extra copies of its genome without dividing, multiplying its number of chromosome sets, or “ploidy.”

Deep Learning without Deep Pockets

Now that you’ve transformed your system through successive evolutions of architecture goodness...you've made it cloud native, you now treat a fist full of datacenters as a single computer, you’ve microservicized it, you’ve containerized it, you’re continuously releasing and improving it, you’ve made it reactive, you’ve socialized it, you’ve mobilized it, you’ve Hadoop’ed it, you’ve made it DevOps friendly, and you have real-time dashboards that would make NORAD jealous...what’s next?

Deep learning is what’s next. Making machines that learn. The problem is how?

All the other transformations have been changes good programmers can learn to do. Deep learning is still deep magic. We are waiting for the Hadoop of deep learning to be built.

Until then, if you aren’t Google with Google sized clusters and cloisters of PhDs, what can you do? Greg Corrado, Senior Research Scientist at Google, gave a great presentation at the RE.WORK Deep Learning Summit 2015 (videos) that has some useful suggestions:

HappyPancake: a Retrospective on Building a Simple and Scalable Foundation

This is a guest repost by Rinat Abdullin, who worked on HappyPancake, the largest free dating site in Sweden. Initially written in ASP.NET and MS SQL Database server, it eventually became overly complex and expensive to scale. This is the last post in a nearly two year long series of engaging articles on the evolution of the project. For the complete list please see the end of this article.

Our project at HappyPancake completed this week. We delivered a simple and scalable foundation for the next version of largest free dating web site in Sweden (with presence in Norway and Finland).

Journey

Below is the short map of that journey. It lists technologies and approaches that we evaluated for this project. Yellow regions highlight items which made their way into the final design.

Stuff The Internet Says On Scalability For February 20th, 2015

Hey, it's HighScalability time:


Networks are everywhere, they can even help reveal disease connections.
  • trillions: number of photons constantly hitting your eyes; $19 billion: Snapchat valuation;  8.5K: average number of questions asked on Stack Overflow per day
  • Quotable Quotes:
    • @BenedictEvans: End of 2014: 3.75-4bn mobiles ~1.5bn PCs  7-800m consumer PCs 1.2-1.3bn closed Android 4-500m open Android 650-675m iOS 80m Macs, ~75m Linux
    • @JeremiahLee: “Humans only use 10% of their internet.” —@nvcexploder #NodeSummit
    • beguiledfoil: Javavu - The feeling experienced when you see new languages make the same mistakes Java made 20 years ago and momentarily mistake said language for Java.
    • @ewolff: If Conway's Law is so important - are #Microservices more an organizational approach than an architecture?
    • @KentLangley: "Apache Spark Continues to Spread Beyond Hadoop." I would say supplant. 
    • Database Soup: An in-memory database is one which lacks the capability of spilling to disk.
    • Matthew Dillon: 1-2 year SSD wear on build boxes has been minimal.
    • @gwenshap: Except there is one writer and many readers - so schema and validation must be done on ingest. Anywhere else is just shifting responsibility
    • @jaykreps: Startup style of engineering (fail fast & iterate) doesn't work for every domain, esp. databases & financial systems
    • Taulant Ramabaja: Decentralization is not a goal in and of itself, it is a strategy
    • Eli Reisman: Etsy runs more Hadoop jobs by 7am than most companies do all day.
    • Dormando: We're [memcached] not sponsored like redis is. I've only ever lost money on this venture.
    • The Trust Engineers: There are more Facebook users than Catholics.

  • Exponent...The new integration is hardware + software + services. Not services like disk storage, but services  like HomeKit, HealthKit, Siri, Car Play, Apple Pay. Services that touch every part of our lives. Apple doesn't build cars, stores, or information services, it wraps them with an Apple layer that provides the customer with an integrated experience while taking full advantage of modularity. Modularity wrapped with integration. Owning the hardware is a better profit model than sercvices in the cloud.

  • Quite a response to You Don't Like Google's Go Because You Are Small on reddit. A vigorous 500+ comments were written. Golang isn't perfect. How disappointing, so many things are.

  • After making Linux work well on multiple cores that next bump in performance comes from Improving Linux networking performance. It's a hard job. For a 100Gb adapter on 3GHz CPU there are only about 200 CPU cycles to process each packet. Good break down of time budgets for for various instructions. The approach is improved batching at multiple layers of the stack and better memory management, which leads directly into Toward a more efficient slab allocator.

  • The process behind creating a Google Doodle for Alessandro Volta’s 270th Birthday reminds me a lot of the process of making old style illustrations as described in Cartographies of Time: A History of the Timeline. The idea is to encode symbolically as much of the important information as possible in a single diagram. The coded icon of a tiny skull could mean, for example, a king died while on the throne. A single flame could stand for the fall of man. This art is not completely lost with today's need to convey a lot of information on small screens. This sort of compression has advantages: Strass believed that a graphic representation of history held manifold advantages over a textual one: it revealed order, scale, and synchronism simply and without the trouble of memorization and calculation.

Free Book: Is Parallel Programming Hard, And, If So, What Can You Do About It?

The trouble ain’t that people are ignorant: it’s that they know so much that ain’t so." -- Josh Billings

 

Is Parallel Programming Hard? Yes. What Can You Do About It? To answer that, Paul McKenney, Distinguished Engineer at IBM Linux Technology Center, vetran of parallel powerhouses SRI and Sequent, has written an epic 400+ page book: Is Parallel Programming Hard, And, If So, What Can You Do About It? 

The goal of the book? "To help you understand how to design shared-memory parallel programs to perform and scale well with minimal risk to your sanity."

So it's not a book about parallelism in the sense of getting the most out of a distributed system, it's a book in the mechanical-sympathy sense of getting the most out of a single machine.

Some example section titles: Introduction, Alternative to Parallel Programming, What Makes Parallel Programming Hard, Hardware and its Habits, Tools of the Trade, Counting, Partitioning and Synchronized Design, Locking, Data Ownership, Deferred Processing, Data Structures, Validation, Formal Verification, Putting it All Together, Advanced Synchronization, Parallel Real-Time Computing, Ease of Use, Conflicting Visions of the Future.

To get a feel for the kind of things you'll learn in the book, here's an interview where Paul talks about what in parallel programming is the hardest to master:

Scaling Kim Kardashian to 100 Million Page Views

The team at PAPER estimated their article (NSFW) containing pictures of a very naked Kim Kardashian would quickly receive over 100 million page views. The very definition of bursty viral driven traffic.

As a comparison in 2013 it was estimated Google processed over 500 million searches a day. So a nude Kim Kardashian is worth one-fifth of a Google. Strangely, I can believe it.

How did they handle this traffic gold mine? A complete recounting of the unusual behind the scenes story is told by Paul Ford in How PAPER Magazine’s web engineers scaled their back-end for Kim Kardashian (SFW).  (BTW, only one butt pun was made intentionally in this story, all others are serendipity).

What can we learn from the experience? I know what you are thinking. This is just a single static page with a few static pictures. It’s not a complex problem like search or a social network. Shouldn’t any decent CDN be enough to handle that? And you would be correct, but that’s not the whole of the story:
