+0 Vote Up -0Vote Down
As businesses head into the cloud, it is tempting to reach for the first product that offers to make database operation as simple as punching a few buttons on a menu.  However, there’s a big difference between firing up cloud database services such as Amazon RDS for testing or development and finding a solution that can handle hundreds of millions of transactions daily. This webinar-on-demand

Crisis Management During Sandy

The news this past week has brought endless images of devastation. All metropolitan region, the damage is apparent.

More than once in conversation I’ve commented “That’s similar to what I do.” The response is often one of confusion. So I go on to clarify. Web operations is every bit about disaster recovery and crisis management in the datacenter. If you saw Con Edison down in the trenches you might not know how that power gets to your building, or what all those

    Controlled failover simplicity with MySQL
    +3 Vote Up -0Vote Down

    As part of a recent engagement, I described the relative products to manage a MySQL pair (i.e. an Active/Passive MySQL masters configuration). This included the steps to undertake a controlled failover for supporting software maintenance using manual procedures. The upcoming Effective MySQL: Replication Techniques in Depth book details each step and all conditions to review over a dozen pages. While the steps are straightforward and generally well known, scripting this for your environment takes a certain amount of work to ensure your information is correct, and application connectivity loss is kept to a minimum.

    In Continuent Tungsten (which I have just been reviewing these past few weeks), I achieved the same result with a single command.

    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.

    On the other end, management and their bean counters would

    Read the original article at The Mythical MySQL DBA

    I’ve  been getting more than my fair share of calls from recruiters of late. Even in this depressed economic climate where jobs are rarer than a cab at rush-hour, it’s heartening to know that tech engineers are in great demand. And it’s even more heartening to think that demand for MySQL DBAs has never been better.

    My reckoning was confirmed by a Bloomberg news report about stalwart retailers suffering from a dearth of talented engineers. Bloomberg cited Target’s outage-prone e-commerce site as a symptom of, among other things the market’s shortage. One of the challenges old-timers like Target face is having to compete with Silicon Valley startups

    Top 3 Questions From Clients

    1. This page or area of the website is very slow, why?

    There are a lot of components that make up modern internet websites, and a lot of places to get stuck in the mud.  Website performance starts with the browser, what caching it is doing, their bandwidth to your server, what the webserver is doing (caching or not and how), if the webserver has sufficient memory, and then what the application code is doing and lastly how it is interacting with the backend database.

    With all this complexity, it's no wonder so many sites struggle.  Typically these types of analysis start with some load testing, to stress test your setup, so you can watch for leaks.  Then

    5 Ways to Avoid EC2 Outages
    +0 Vote Up -0Vote Down

    1. Backup outside of the Cloud

    Some of the high profile companies affected by Amazon's April 2011 outage could have recovered had they kept a backup of their entire site outside of the cloud.  With any hosting provider, managed traditional data center or cloud provider, alternate backups are always a good idea.  A MySQL logical backup and/or incremental backup can be copied regularly offsite or to an alternate cloud provider.  That's real insurance!

    2. Use alternate regions and availability zones

    Disaster @ Tumblr
    +2 Vote Up -0Vote Down
    Tumblr has been down for more than 12 hours due to an issue with their database cluster. Here is the comment I left on GigaOm.com

    This is the freshest lesson for entrepreneurs and startups:
    - Learn to value your data
    - Implement a high availability plan
    - Plan a disaster recovery strategy

    “Tumblr likely has the resources to recover…”

    I really hope that holds out true but remember, data is the only irreplaceable asset of an organization. Once it’s gone, it’s gone.

    When I was handling the disaster at Fotolog (massive database corruption when our SAN crashed), I couldn’t find any company or consulting firm ready to handle the situation and help with data recovery. It was a miracle that I came

    Different Technology Stacks On Production and DR?

    Last week, I was at the NetApp office in North Sydney for the presentation on NetApp SnapManager for Oracle. It was good opportunity to learn more about NetApp snapshots while working on a project for one of our clients in Sydney. It was an especially interesting topic as I have some experience using Veritas Checkpoints (see my presentation on test systems refreshes), and it was interesting to see what’s different and new in the NetApp implementation. But I digress.

    I learned that NetApp can provide access to the same LUNs via either Fiber-Channel (FC) or iSCSI. And this is when the interesting argument surfaced. Apparently, some companies aim to
