Mac OS X: The Love Affair Is Over
+1 Vote Up -0Vote Down
Like a lot of developers I started using a MacBook Pro around the time of Tiger.  I instantly loved it:  simple, fast, and virtually no system administration overhead. The genius of OS X was that it never got in the way. You opened the box, pulled out the machine, and got to work. It had a great user interface, excellent  development tools (Eclipse in my case) and the command utilities like ssh, rsync, and bash worked seamlessly with Linux systems.

Well, that was then and this is now. Starting with Lion I began to spend an increasing amount of time fighting OS X instead of getting work done. I'm now using Mavericks and have not seen much improvement, in fact quite the contrary. Here are just a few of the problems after the Lion to Mavericks upgrade:
  • Spotlight indexes destroyed; need 2 days to regenerate
  • AppleMail access

Introducing Data Fabric Design for Commodity SQL Databases
+2 Vote Up -0Vote Down
Data management is undergoing a revolution.  Many businesses now depend on data sets that vastly exceed the capacity of DBMS servers.  Applications operate 24x7 in complex cloud environments using small and relatively unreliable VMs.  Managers need to act on new information from those systems in real-time. Users want constant and speedy access to their data in locations across the planet.

It is tempting to think popular SQL databases like MySQL and PostgreSQL have no place in this new world.  They manage small quantities of data, lack scalability features like parallel query, and have weak availability models.  One reaction is to discard them and adopt alternatives like Cassandra or MongoDB.  Yet open source SQL databases have tremendous strengths:  simplicity, robust transaction support, lightning fast operation, flexible

We have started a new series of webinars at Continuent that we call Tungsten University.  They provide education on Tungsten clustering and replication in handy one-hour chunks.  These are not sales pitches.  Our goal is to provide accessible education about setting up and operating Tungsten without any marketing fluff.

The first Tungsten University webinar entitled "Configure & provision Tungsten clusters" will take place on Thursday January 17th at 10:00 PST.  It will show you how to set up a cluster in Amazon EC2.  There will be a repeat on January 22nd at 15:00 GMT.  We usually record webinars, so you can look at them later as well.

    The fall conference season is starting.  I will be doing a number of talks including a keynote on "future proofing" MySQL through the use of data fabrics.  Data fabrics allow you to build durable, long-lasting systems that take advantage of MySQL's strengths today but also evolve to solve future problems using fast-changing cloud and big data technologies.  The talk brings together ideas that Ed Archibald (our CTO) and I have been working on for over two decades.  I'm looking forward to rolling them out to a larger crowd.

    Life in the Amazon Jungle
    +1 Vote Up -0Vote Down
    In late 2011 I attended a lecture by John Wilkes on Google compute clusters, which link thousands of commodity computers into huge task processing systems.  At this scale hardware faults are common.  Google puts a lot of effort into making failures harmless by managing hardware efficiently and using fault-tolerant application programming models.  This is not just good for application up-time.  It also allows Google to operate on cheaper hardware with higher failure rates, hence offers a competitive advantage in data center operation.

    It's becoming apparent we all have to think like Google to run applications successfully in the cloud.  At Continuent we run our IT and an increasing amount of QA and development on Amazon Web

    Is Synchronous Data Replication over WAN Really a Viable Strategy?
    +3 Vote Up -0Vote Down
    Synchronous data replication over long distances has the sort of seductive appeal that often characterizes bad ideas.  Why wouldn't you want every local credit card transaction simultaneously stored on the other side of the planet far away from earthquake, storms and human foolishness?  The answer is simple: conventional SQL applications interact poorly with synchronous replication over wide area networks (WANs).

    I spent a couple of years down the synchronous replication rabbit hole in an earlier Continuent product.  It was one of those experiences that make you a sadder but wiser person.  This article digs into some of the problems with synchronous replication and shows why another approach, asynchronous multi-master replication, is currently a better way to manage databases connected by

    The stealth success of PostgreSQL

    One of the more notable success stories of the open source world is in the field of databases. A company with a strong commitment to open source has seen tremendous growth and success in the enterprise while contributing to a hugely respected open source code base. Who is that? Maybe your first thought was MySQL, now owned by Oracle. But unlike MySQL, this company is actually taking business away from Oracle so effectively that it's seen an 80 percent revenue growth in the last year.

    Autoscaling MySQL on Amazon EC2

    Read the original article at Autoscaling MySQL on Amazon EC2

    Autoscaling your webserver tier is typically straightforward. Image your apache server with source code or without, then sync down files from S3 upon spinup. Roll that image into the autoscale configuration and you’re all set.

    With the database tier though, things can be a bit tricky. The typical configuration we see is to have a single master database where your application writes. But scaling out or horizontally on Amazon EC2 should be as easy as adding more slaves, right? Why not automate that process?

    We've all seen cloud computing discussed ad nauseam on blogs, on Twitter, Quora, Stack Exchange, your mom’s Facebook page... you get the idea. The tech bloggers and performance experts often pipe in with their graphs and statistics showing clearly that dollar-for-dollar, cloud hosted virtual servers can’t compete with physical servers in performance, so why is everyone pushing them? It's just foolhardy, they say.

    $1000 per hour Servers, Anyone?

    Read the original article at $1000 per hour Servers, Anyone?

    Amazon's spot market for computing power is set up as an open market for surplus servers. The price is dynamic and depends on demand. So when demand is low, you can get computing instances for rock bottom prices. When you do that you normally set a range of prices you're willing to pay. If it goes over your top end, your instances get killed and re-provisioned for someone else. Obviously this wouldn't work for all applications, like a website that has to be up all the time, but for computing power, say to run some huge hedge fund analytics, it might fit perfectly.

    Got open source cloud storage? Red Hat buys Gluster
    +0 Vote Up -0Vote Down

    Red Hat’s $136m acquisition of open source storage vendor Gluster marks Red Hat’s biggest buy since JBoss and starts the fourth quarter with a very intersting deal. The acquisition is definitely good for Red Hat since it bolsters its Cloud Forms IaaS and OpenShift PaaS technology and strategy with storage, which is often the starting point for enterprise and service provider cloud computing deployments. The acquisition also gives Red Hat another weapon in its fight against VMware, Microsoft and others, including OpenStack, of which Gluster is a member (more on that further down). The deal is also good for Gluster given the sizeable price Red Hat is paying for the provider of open source, software-based, scale-out storage for unstructured data and also as validation of both open source and software in

    Open Source Hardware

    Back in 2010 I stopped buying test servers from Dell and began building them from components using Intel i7 processors, X58-based mother boards, and modular power supplies from Ultra.  It was a good way to learn about hardware.  Besides, it was getting old to pay for Dell desktop systems with Windows, which I would then wipe off when installing Linux.  Between the educational value of understanding the systems better, selecting the exact components I wanted, and being able to fix problems quickly, it has been one of the best investments I have ever made.  And it didn't cost any more than equivalent Dell servers.

    For this reason, a couple of recent articles about computer hardware caught my attention.  First, Dell is losing business

    It’s been some time now that we’ve been talking about devops, the pushing together of application development and application deployment via IT operations, in the enterprise. To keep up to speed on the trend, 451 CAOS attended PuppetConf, a conference for the Puppet Labs community of IT administrators, developers and industry leaders around the open source Puppet server configuration and automation software. One thing that seems clear, given the talk about agile development and operations, cloud computing, business and culture, our definition of devops continues to be accurate.
