My name is Summer Nguyen, from Ho Chi Minh City, Vietnam. I am working as a System Engineer in Linux, especially CentOS.

I am bad at writting even in my native language, Vietnameses. I had my plan a long time ago writing my notes about everything I did, sharing my experiences to the community and get feedbacks. But until now, I’ve start my first ever post.

I will usually write about the tasks, technologies I used at my company in some sections :

Basic

• Linux basic and useful commands
• Tutorial how to use some common softwares : git, gitlab, jenkins, DNS management, ..
• Debugging , fixxing some problems I got.

Advance

• Architecture Design for some systems : CDN, Web Farm, CDN
• Tunnings for kernel, web servers, database servers,…
• Cloud Infrastructure : CloudStack
• Automate system deployment using Puppet, Ansible, …

Big Data

• Hadoop HDFS
• Central Log Management using : Scribe, Fluentd , Graylog, … intergrated with Hadoop

Hope this will help me improve my English writing skill and somehow helping people in someway.

Have a nice day..
