Introduction: There's a deep similarity between how long running systems like our brains and computers accumulate errors and repair themselves.  Reboot it. Isn’t that the common treatment for most computer ailments? And you may have noticed now that your iPhone supports background processing it reboots a lot more often? Your DVR, phone, computer, router, car, and an untold number of long running computer systems all suffer from a nasty problem: over time they accumulate flaws and die or go crazy. Now think about your brain. It’s a long running program running on very complex and error prone hardware. How does your brain keep itself sane over time? The answer may be found in something we spend a third of our lives doing. Sleep. There’s new research out on how our brains are cleansed during sleep that has some interesting parallels to how we keep long running hardware-software systems up and running properly. This is a fun topic. Let’s explore it a little more. One of the most frustrating

Introduction: Here's a common situation and question from the mechanical-sympathy Google group by Avinash Agrawal on the black art of capacity planning: How to get started with sizing and capacity planning, assuming we don't know the software behavior and its completely new product to deal with? Gil Tene , Vice President of Technology and CTO & Co-Founder, wrote a very  understandable and useful answer  that is worth highlighting: Start with requirements. I see way too many "capacity planning" exercises that go off spending weeks measuring some irrelevant metrics about a system (like how many widgets per hour can this thing do) without knowing what they actually need it to do. There are two key sets of metrics to state here: the "how much" set and the "how bad" set: In the "How Much" part, you need to establish, based on expected business needs, Numbers for things (like connections, users, streams, transactions or messages per second) that you expect to interact with at the peak t

5 high scalability-2013-12-16-22 Recommendations for Building Effective High Traffic Web Software

Introduction: This is a guest post by Ashwanth Fernando, Software Engineer from the trenches at large scale internet companies. Inspired by the book "Effective Java" by Joshua Bloch, I wanted to share my holistic recommendations on building high traffic web software (i.e. web applications/services that serve high traffic loads). Some of these items may not be just about software design but also around surrounding areas such as the engineering organization, culture etc. Two disclaimers up front: 1) This is my opinion. 2) There will be real world situations where the below principles will be wrong as in all things "software". Please use common sense all the time. Consider using more than one datacenter There have been numerous horror stories about businesses, ahem going out of business because they just had a single datacenter. Its really important to have more than one data center if you want to protect yourself from natural disasters or electrical supply failures. Run all your datacen

Introduction: PayPal gives yet  another glowing report of an app rewritten in node.js experiencing substantial performance improvements. PayPal rewrote their account overview page, one of the most trafficked apps on the website, which was previously written in King Java. The benefits: Full-stack engineers. Using JavaScript on both the front-end and the back-end removed an artificial boundary between the browser and server, allowing engineers to code both. Built almost twice as fast with fewer people  Written in 33% fewer lines of code  Constructed with 40% fewer files Double the requests per second vs. the Java application. 35% decrease in the average response time for the same page. A common pro Java response is an argument like clearly these people don't know how to program Java. Or rewriting an application usually makes it faster. Or the benchmark is faulty. And so on. Consider it noted. These are all potential factors. Baron Schwartz from VividCortex has a different tak

9 high scalability-2013-12-09-Site Moves from PHP to Facebook's HipHop, Now Pages Load in .6 Seconds Instead of Five

Introduction: If you code in PHP have you ever wondered about moving to Facebook's HipHop JIT Virtual Machine for PHP ? With HipHop Facebook achieved over a 9x increase in web request throughput and over a 5x reduction in memory consumption compared to Zend PHP 5.2 engine + APC. But will HipHop really work for you? Is it really drop-in compatible? Is it really as fast as they say? To answer questions like this nothing beats a good experience report and here's a great one: Adventures in Configuring and Running Facebook's HipHopVM (hhvm) JIT Compiler for PHP  by Yermo Lamers. Yermo selected PHP to implement a number of content web sites. He took an interesting approach, he created a forms, views, validation, and business logic description language to remove the drudgery of creating the same code over and over again for each page. Having done this in Perl I think it's a great a approach. The problem is it can be slow. PHP's slow string handling makes dynamically evaluating a description templat

10 high scalability-2013-12-09-In Memory: Grace Hopper to Programmers: Mind Your Nanoseconds!

Introduction: This is an article published last year, but as today is Grace Hopper's birthday I thought it would be a good time to share again an amazing talk from this amazing woman. Computing pioneer Grace Hopper , inventor of the compiler , searched for a concrete way to create an intuitive understanding of just how fast is a nanosecond, a billionth of a second, which was the speed of their new computer circuits. As an illustration she settled on the length of wire that is as long as light can travel in one nanosecond. The length is a very portable 11.8 inches . A microseconds worth of wire is a still portable, but a much bulkier 984 feet. In one millisecond light travels 186 miles, which only Hercules could carry. In today's terms, at a 3.06 GHz clock speed , there's .33 nanoseconds between ticks, or 3.73 inches of light travel. Understanding the profligate ways of programmers, she suggests that every programmer wear a necklace of a microseconds worth of wire so they know what they are

12 high scalability-2013-12-04-How Can Batching Requests Actually Reduce Latency?

Introduction: Jeremy Edberg gave a talk on  Scaling Reddit from 1 Million to 1 Billion–Pitfalls and Lessons  and one of the issues they had was that they: Did not account for increased latency after moving to EC2. In the datacenter they had submillisecond access between machines so it was possible to make a 1000 calls to memache for one page load. Not so on EC2. Memcache access times increased 10x to a millisecond which made their old approach unusable. Fix was to batch calls to memcache so a large number of gets are in one request. Dave Pacheco had an interesting question about batching requests and its impact on latency: I was confused about the memcached problem after moving to the cloud.  I understand why network latency may have gone from submillisecond to milliseconds, but how could you improve latency by batching requests? Shouldn't that improve efficiency, not latency, at the possible expense of latency (since some requests will wait on the client as they get batched)?

13 high scalability-2013-12-02-Evolution of Bazaarvoice’s Architecture to 500M Unique Users Per Month

Introduction: This is a guest post written by Victor Trac , Cloud Architect at Bazaarvoice . Bazaarvoice is a company that people interact with on a regular basis but have probably never heard of. If you read customer reviews on sites like bestbuy.com, nike.com, or walmart.com, you are using Bazaarvoice services. These sites, along with thousands of others, rely on Bazaarvoice to supply the software and technology to collect and display user conversations about products and services. All of this means that Bazaarvoice processes a lot of sentiment data on most of the products we all use daily. Bazaarvoice helps our clients make better products by using a combination of machine learning and natural language processing to extract useful information and user sentiments from the millions of free-text reviews that go through our platform. This data gets boiled down into reports that clients can use to improve their products and services. We are also starting to look at how to show per

Introduction: The story of driving the golden spike to symbolize the completion of the transcontinental railroad  is famous in the US. What is not so well known is the story of how it also foreshadowed changes to come as an early version of both the Internet and the Internet of Things. But that was 1869, how can that possibly be? Telegraph as Internet First, let's establish the telegraph and cable systems was an early version of an Internet. As railroad tracks were being laid a transcontental telegraph system was also being constructed. Telegraph lines were installed parallel to the tracks making instant communication available across the continent, faster than any horse could ride. With the  transalantic cable system  information could quickly span continents in minutes: The miles of American telegraph grew from 40 in 1846 to 12,000 in 1850 to 23,000 in 1852. In Europe it increased from 2,000 in 1849 to 110,000 in 1869. The cost of sending 10 words was $1.55 in 1850, $1 in 1870, 40

Introduction: This is a guest post by  Mark Travis , Founder of InfiniSQL . InfiniSQL is the specific "Infinitely Scalable RDBMS" to which the title refers. It is free software, and instructions for getting, building, running and testing it are available in the guide . Benchmarking shows that an InfiniSQL cluster can handle over 500,000 complex transactions per second with over 100,000 simultaneous connections, all on twelve small servers. The methods used to test are documented, and the code is all available so that any practitioner can achieve similar results. There are two main characteristics which make InfiniSQL extraordinary: It performs transactions with records on multiple nodes better than any clustered/distributed RDBMS It is free, open source. Not just a teaser "community" version with the good stuff proprietary. The community version of InfiniSQL will also be the enterprise version, when it is ready. InfiniSQL is still in early stages of development--it already has m

Introduction: Netty is a high-performance  NIO (New IO) client server framework for Java that Twitter uses internally as a protocol agonostic RPC system. Twitter found some problems with Netty 3's memory management for buffer allocations beacause it generated a lot of garbage during operation. When you send as many messages as Twitter it creates a lot of GC pressure and the simple act of zero filling newly allocated buffers consumed 50% of memory bandwidth.  Netty 4 fixes this situation with: Short-lived event objects, methods on long-lived channel objects are used to handle I/O events. Secialized buffer allocator that uses pool which implements buddy memory allocation and slab allocation . The result: 5 times less frequent GC pauses: 45.5 vs. 9.2 times/min 5 times less garbage production: 207.11 vs 41.81 MiB/s The buffer pool is much faster than JVM as the size of the buffer increases. Some problems with smaller buffers. Given how many services use the JVM in thei

Introduction: In 1999 Dan Kegel issued a big hairy audacious challenge to web servers: It's time for web servers to handle ten thousand clients simultaneously, don't you think? After all, the web is a big place now. This became known as the C10K problem . Engineers solved the C10K scalability problems by fixing OS kernels and moving away from threaded servers like Apache to event-driven servers like Nginx and Node. Today we are considering an even bigger goal, how to support 10 Million Concurrent Connections , which requires even more radical techniques. No similar challenge was issued for managing servers in a datacenter, but according to Dave Neary from Red Hat, in a recent FLOSS Weekly  episode , we have passed the 10K barrier for server management with 10,000 or more servers managed per sysadmin. Should we let this milestone pass without mention? Absolutely not! It’s a stunning accomplishment with 200x-2000x increases in productivity. Dave said h
