A History lesson for Cloud Detractors

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 simply roll their eyes saying this is why the tech guys aren't running the business.

The Mythical MySQL DBA

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 as a …

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 some tools are applied to the webserver tier, and the database tier to see where the bottleneck lies.  It may be in the network …

5 Ways to Avoid EC2 Outages

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

Amazon's outage in April …

Disaster @ Tumblr

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 across the concept of DUDE (Data …

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 have the technology stack on their …
