About
My name is Catherine Liao and you're reading the latest postings of various blogs I follow. You'll notice that the topics tend to center around Cloud Computing, Data Center, Virtualization, Servers, Web Technologies and 24x7 Operations.
These are topics that I'm interested in as I've spent a large chunk of my professional career building, deploying, and maintaining 24x7 application delivery environments. I use the knowledge I've garnered daily in my role as a Technology Solutions Architect for Cisco. I should note that this site is my personal site and does not reflect the views of Cisco.
Feel free to drop me a note if you find this site useful or if you'd like for me to check out your blog. I can be reached at catherine.liao@gmail.com. You can also connect with me via LinkedIn or Twitter.
