Performance and Scaling in Enterprise Systems

This is a guest post from Vlad Mihalcea the author of the High-Performance Java Persistence book, on the notion of performance and scalability in enterprise systems.

An enterprise application needs to store and retrieve as much data and as fast as possible. In application performance management, the two most important metrics are response time and throughput.

The lower the response time, the more responsive an application becomes. Response time is, therefore, the measure of performance. Scaling is about maintaining low response times while increasing system load, so throughput is the measure of scalability.

Response time and throughput

Stuff The Internet Says On Scalability For May 6th, 2016

Hey, it's HighScalability time:


Who wants in on the over? We are not alone if the probability a habitable zone planet develops a technological species is larger than 10-24.

 

If you like this sort of Stuff then please support me on Patreon.
  • 100,000+: bare metal servers run by Twitter; 10 billion: Snapchat videos delivered daily; $2.57 billion: AWS fourth quarter revenues; 40 light years: potentially habitable planets; 1700: seed banks around the world; 560x: throughput after SSD optimization; 12: data science algorithms; $2.8 billion: new value of Pivotal’s Cloud Foundry;  

  • Quotable Quotes:
    • @skap5: Pied Piper's product is its stock and anything that makes its price go up! #SiliconValley
    • Seth Godin: It pays to have big dreams but low overhead. 
    • Craig Venter~ Our knowledge of the genome hasn't changed a lot since 2003, but it's about to start changing rapidly. One of the key things for understanding the genome is to get very large numbers of genomes so we can understand out of the 6.2 billion or so letters of genetic code the less than 3% that we have different amongst the entire human population. We need very large data sets to understand the differences and significances. That's where the cost and speed of sequencing has had such an immediate impact. 
    • @elonmusk: Rocket reentry is a lot faster and hotter than last time, so odds of making it are maybe even, but we should learn a lot either way
    • @EconBizFin: The space race was once between capitalism and communism. Now it's individual capitalists
    • Grit: substitute nuance for novelty. Rather than constantly moving on to a new thrill try to find another dimension of the thing you are already doing to make it more thrilling. 
    • David Rosenthal: Overall the message is: Storage Will Be Much Less Free Than It Used To Be
    • StorageMojo: The losers are the systems that make customers pay for features they no longer need. Winners will successfully blend ease of use with performance and availability – at a competitive price.
    • Tim Harford: These distractions were actually grists to their creative mill. They were able to think outside the box because their box was full of holes.
    • Juan Enriquez~ Plastics was the wrong advice to Dustin Hoffman in The Graduate. The word should have been silicon. In 2015 the word is lifecode, the various means we have to program life.
    • Benjamin Treynor Sloss: If you've ever wondered about how run reliable services, this beautifully written intro from the SRE book is the best 5-minute guide on the topic.
    • cs702: Without AWS, Amazon would have reported losses! 
    • Kode Vicious: A single cache miss is more expensive than many instructions.
    • @aminggs: “your database… unlikely to provide serializability, your multi-core processor… unlikely to provide linearizability” 
    • @mrogati: A decade in academia taught me a bunch of sophisticated algorithms; a decade in industry taught me when not to use them.
    • @mjpt777: Hardware tries so hard to make software fast; software tries so hard to make hardware slow.
    • @jyarow: Echo sold 3 million units. Gets stories that it’s next great business for Amazon. Apple Watch sold 12 million units, gets panned as a flop.
    • @balajis: 5/ At that time, the highest truth comes not from faith in god or trust in the state, but from the ability to check the math of the network.
    • Benedict Evans: The smartphone install base does have a lot of room to grow, but that's a function of replacement at close to existing volumes, and even that will be largely done in a few more years. Hence: smartphone sales growth is slowing down. 
    • @giupan: Colocated teams where Devs are sitting together with Product and UX outperform distributed teams. Don't split up skills @cagan #craftconf
    • Mathias Bynens: To me, this stuff is extremely interesting on a technical level. It’s also a little scary, however, to realize that malicious actors can use these techniques to invade your privacy while you’re browsing the web, without you ever knowing.
    • Le Corbusier: yes, the Parthenon is perhaps the most beautiful instance, the perfect example of a particular standard of architecture. The Parthenon may have achieved the platonic ideal of the standard of architecture we’ve previously established. But there are many possible standards to acknowledge, each dependent on need and use, and standards are established by experiment.
    • PaulHoule: Atom chips have always been crippled to keep them from cannibalizing more expensive chips. Skylake is a fine tablet chip, in fact, that's really what Skylake is good for. They are probably producing them in high enough numbers now that they can give up on Atom
    • Chau Tu: CyArk wants to preserve our world’s important cultural heritage sites before they turn to dust...with new imaging technologies to steadily build a digital archive of the past, for the future. 
    • Neill Turner: Over time i think OpenStack will be a niche product for large corporates that don’t want to use public clouds. For everyone else they with be doing hybrid IT – that is extending their existing IT infrastructure into the Public Cloud. When they see what is left to run to run outside public clouds then they can see where to take that portion of the workloads.

  • What if going to Mars is how we fix our economy? Trump: Before going to Mars, America needs to fix its economy. A problem can't be solved at the same level it was created. Someone smart said that once. Isn't expanding the economy in to space the only way we'll be able to generate the constant growth a modern economy so desperately devowers? Walls don't lift boats.

  • Is it dystopian to hire real meat people to train your AI? Interesting question posed by John Robb in a tweet: "they were there not to work, but to serve as training modules for Facebook’s algorithm" Journos at Fbook

  • Peter Bailis offers in a heartfelt visionary article four pieces of advice to get the database community out of its identity crisis: 1) Kill the reference architecture and rethink our conception of “database.” 2) Solve new, emerging, real problems outside traditional relational database systems. 3) Use data-intensive tools, both the tools that you’re building and the tools that others have built. 4) Do bold, weird, and hard projects and actually follow through. Examples in action: Peter Alvaro’s work on Molly and Lineage-Driven Fault Injection; Chris Ré’s work on DeepDive; A recent project I wish the database community had done is TensorFlow at Google.

  • Quotable Quotes:
    • @antevens: -> Describe your perfect date. ......<- YYYY-MM-DD HH:MM:SS.XXXXXX
    • @ValaAfshar: 1995: top 15 Internet companies worth $17 billion. 2015: top 15 Internet companies worth $2.4 trillion.
    • @BenedictEvans: The move to mobile took away Facebook's monopoly of social, but gave it much greater scale, engagement & revenue potential.
    • Sundar Pichai: We will move from mobile first to an AI first world.
    • Chris Sacca~ We [Google] literally could feel a scale that had never been felt before on the planet. We had a globe where you could visualize in searches in real-time. A dot would indicate every single search on the planet. In the middle of the night there would be a search in the Gobi desert.
    • @stack72: Just had a recruiter contact me about a role with "microservices on a servers architecture” - twice I’ve seen that now in 2 days #TheFuture?
    • Jason Waxman [Intel]: We see that the world is moving to scale computing in data centers. Our projection is between 70 and 80 percent of the compute, network, and storage will be going into what we call scale data centers by 2025.
    • @BenedictEvans: In 2009 only half of Facebook's MAUs were on it every day. Mobile has taken that to 2/3, at much greater scale.
    • Dan Rayburn: Amazon and Google Enticing Customers With Cheap Storage, But Beware Of Egress Charges
    • @manumarchal: CERN LHC computing challenge is more than 400k CPUs + 300PB of data. It's is also global distribution. #dotScale
    • @bridgetkromhout: Decouple and segregate systems requiring different trust levels for faster iteration. @adrianco #craftconf
    • @dkalintsev: GE on stage at AWS Summit: “50% TCO saving compared to best what we could do in-house”
    • @etherealmind: How messed up was GE management to let their costs get this out of control ?
    • @Ellen_Friedman: #dotscale Oliver Keeble CERN - superb: computing is key. Collisions are transient; data is persisted at huge scale
    • @stratecheryAggregation Theory leads to monopoly; expect more antitrust cases, but only in Europe
    • @kelseyhightower: Moving to microservices won't save you. Borrowing money in smaller chunks doesn't change the fact that you're broke.
    • @jrauser: 1/ Inspired by this HN comment …, I offer a story about software rewrites and Bezos as a technical leader.
    • aytekin: This is a story that has happened over and over again. When you rewrite software, you lose all those hundreds of tiny things which were added for really good reasons. Don't do it blindly.
    • @BWJones: The F-35 program, which at $1.5 T would fund the entire NIH biomedical research portfolio for 41 years.
    • @balinski: "Centralization is a disease" #dotScale #scalability #cloudcomputing
    • Tony Bain: So despite the noise surrounding NoSQL, in a head to head comparison of volume of use, NoSQL use seems so very small.  At a guess, I would predict that for every NoSQL database in existence there would be at least 1000 relational databases.  Probably more.  You would be forgiven for thinking NoSQL use was almost insignificant. 
    • @jaksprats: NVM is gonna put big data on a single machine, very interesting for non-BulkSynchronousParallel GraphDBs like Neo4j
    • @frontofstore: US department stores' sales per sq ft down 26% in last ten years - many closures forecast, anchors killing malls.
    • There are even more Quotable Quotes in the full article. See you there.

  • If you thought HyperCard was a trip you were correct. Bill Atkinson in a fascinating two part Triangulation interview (12) shared that HyperCard was inspired by a LSD trip. It's a far ranging interview that covers Steve Jobs, why the movies about Jobs sucked, Apple's early days, the web's HyperCard inspiration, photography, spirituality, color theory, philosophy, learning, and lots more.

  • In case you were wondering (I certainly was): Pied Piper compression (Silicon Valley HBO). This is the Pied Piper code shown on Silicon Valley HBO Season 3 Episode 1. Worth a deca-unicorn or two.

  • Design Details has a fun podcast with Facebookers talking about Facebook bots and the Facebook design process in general. 124: Dazzle (feat. Jeremy Goldberg). Are bots useful? (yes, but not a convincing argument). Do we have to be nice to bots? (to a point because you never know who if you are talking to a person). Bots aren't all automated, they can be a combination of automated and human interactions. Bots should use strategies to help convince people they are talking with another human, like playing with typing indicator delays to simulate typing. Same for simulating reading. Animation and delays should speed up over time. Regressive design, the idea that over time parts of the UI remove themselves as users use the application more. Fight for designs you believe in. Understand, identify, execute. Truly understand what you are doing at a deep level. Identify the things you can be the most impactful on. Facebook measures you on impact. Lots of talk about design crits and pillars and pillar centered design crits. We often think of ourselves as problem solvers, our job isn't so much problem solving as communicating proposed solutions to problems.

The Platform Advantage of Amazon, Facebook, and Google

Where’s the mag­ic? [Amazon] The databas­ing and stream­ing and sync­ing in­fras­truc­ture we build on is pret­ty slick, but that’s not the se­cret. The man­age­ment tools are nifty, too; but that’s not it ei­ther. It’s the trib­al knowl­edge: How to build Cloud in­fras­truc­ture that works in a fal­li­ble, messy, un­sta­ble world.

Tim Bray, Senior Principal Engineer at Amazon, in Cloud Eventing

Ben Thompson makes the case in Apple's Organizational Crossroads and in a recent episode of Exponent that Apple has a services problem. With the reaching of peak iPhone Apple naturally wants to turn to services as a way to expand revenues. The problem is Apple has a mixed history of delivering services at scale and Ben suggests that the strength of Apple, its functional organization, is a weakness when it comes to making services. The same skill set you need to create great devices is not the same skill set you need to create great services. He suggests: “Apple’s services need to be separated from the devices that are core to the company, and the managers of those services need to be held accountable via dollars and cents.”

If Apple has this problem they are not the only ones. Only a few companies seemed to have cross the chasm of learning how to deliver a stream of new features at a worldwide scale: Amazon, Facebook, and Google. And of these Amazon is the clear winner.

This is the Amazon Web Services console, it shows the amazing number of services Amazon produces, and it doesn’t even include whole new platforms like the Echo:

The Joy of Deploying Apache Storm on Docker Swarm

This is a guest repost from Baqend Tech on deploying and redeploying an Apache Storm cluster on top of Docker Swarm instead of deploying on VMs. It's an interesting topic because of the experience Wolfram Wingerath called it "a real joy", which is not a phrase you hear often in tech. Curious, I asked what made using containers such a good experience over using VMs? Here's his reply:

Being pretty new to Docker and Docker Swarm, I'm sure there are many good and bad sides I am not aware of, yet. From my point of view, however, the thing that makes deployment (and operation in general) on top of Docker way more fun than on VMs or even on bare metal is that Docker abstracts from heterogeneity and many issues. Once you have Docker running, you can start something like a MongoDB or a Redis server with a single-line statement. If you have a Docker Swarm cluster, you can do the same, but Docker takes care of distributing the thing you just started to some server in your cluster. Docker even takes care of downloading the correct image in case you don't have it on your machine right now. You also don't have to fight as much with connectivity issues, because every machine can reach every other machine as long as they are in the same Docker network. As demonstrated in the tutorial, this even goes for distributed setups, as long as you have an _overlay_ network.

 

When I wrote the lines you were quoting in your email, I had a situation in the back of my head that had occurred a few months back when I had to set up and operate an Apache Storm cluster with 16+ nodes. There were several issues such as my inexperience with AWS (coming from OpenStack) and strange connectivity problems relating to Netty (used by Storm) and AWS hostname resolution that had not occurred in my OpenStack setup and eventually cost us several days and several hundred bucks to fix. I really think that you can shield from problems like that by using Docker, simply because your environment remains the same: Docker.

On to the tutorial...

    • Dan Rayburn: By My Estimate, Apple’s Internal CDN Now Delivers 75% Of Their Own Content
    • @BenedictEvans: If Google sees the device as dumb glass, Apple sees the cloud as dumb pipes & dumb storage. Both views could lead to weakness
    • @JordanRinke: We need less hackathons, more apprenticeships. Less bootcamps, more classes. Less rockstars, more mentors. Develop people instead of product
    • @alicegoldfuss: Nagios screaming / Data center ablaze? No / Cable was unplugged
    • Mark Bates: As I was working on the software part time, I was keen to minimise the [cognitive] scope required when making changes. A RoR monolith was the best choice in this case.
    • Google: Our tests have shown that AMP documents load an average of four times faster and use 10 times less data than the equivalent non-amp’ed result.
    • @stevesi: In earning's call @sundarpichai says going “from mobile-first to AI-first world" emphasizing AI and machine learning across services.
    • Rex Sorgatz: Unfortunately, the entire thesis of my story is that having the history of recorded music in your pocket dictates that you will develop tastes outside “the usual.”
    • Newzoo: Clash Royale has rocketed to such quick success because of its strong core gameplay elements combined with some serious pressure to spend real money to keep up with your friends
    • vgt:  I'm going to plug Google Cloud's Preemptible VMs as a simpler alternative to Spot Instances: - Preemptible VMs are sold at a fixed 70% off discount, removing pricing volatility entirely
    • @mfdii~ "Cloud Native" is code words for "rewrite the entire f*cking app"
    • There are so many great Quotable Quotes this week they wouldn't all fit in the summary. Please see the full post to read them all.

  • Imperfection as a strategy. Why a Chip That’s Bad at Math Can Help Computers Tackle Harder Problems: In a simulated test using software that tracks objects such as cars in video, Singular’s approach [computer chips are hardwired to be incapable of performing mathematical calculations correctly] was  capable of processing frames almost 100 times faster than a conventional processor restricted to doing correct math—while using less than 2 percent as much power.

  • Mitchell Hashimoto in The Cloudcast #246  on some cloud trends. Seeing a lot of interest in non-Amazon clouds right now. A lot of interest in Azure is coming from more boring successful companies, not hot Silicon Valley startups.  This is not a clean market segmentation, but there are three flavors of cloud: Google Compute for the green field startup crowd, Amazon for enterprise, and Azure for super-enterprise. One enterprise attractor for Azure is Azure Stack, an on-premises solution. Mitchell is seeing a broad adoption of the cloud across industries you may not expect to be using the cloud. Also seeing a transition to a multi-cloud strategy to create pricing leverage. The idea seems to be to rehearse and plan to move to another cloud, though they may not actually do it, but when pricing negotiations come up there's a lot of leverage saying you can move to a completely different platform. The cloud is not so much a pay as you go model for this use case, it's more about trying to lock-in long term cost savings. International companies are interested in price, but also what features are available in different regions and when they become available.
