Talking about AWS Migration Solution at iJAWS 2nd meetup

I recently got an opportunity to be a lightning talk speaker at iJAWS(*) 2nd meetup on 5th Feb in Japan and talked about AWS Migration Solution. It was a quite exciting experiment for me because it was my first time to make a presentation about AWS in English. We have also a special guest, Mark Taylor, CTO at Moneytree, Inc, who talked about SWF use case at his company and other 2 lightning talk speakers. I am deeply thankful to Shindou-san who held the event and gave me this opportunity. It is a great honor to be given such an opportunity to present there.

The theme of the presentation is as follows:
  • Why Migration Solution is needed
  • Introducing my case of migrating system
  • System Migration Model and issues of System Migration
  • Introducing AWS Migration Solution
    • Features of One Hybrid Cloud by CloudVelocity
    • Features of Bolt VTA by Yuruware
  • Subject of AWS VM Import/Export for Linux

I believe that system migration by using migration solution is not common so far because system migration itself is tiresome work and manual system migration is common. But we can also learn the various skills from system migrating, such as system assessment, reverse engineering, application synchronization, data synchronization, end so on.

"iJAWS aims to be the international, English speaking, community within the JAWS. The main focus will be events focused on presentations and lightning talks to discuss and share information regarding AWS. iJAWS will also be aimed at power users, hoping to make it a thought leader in the Japanese tech community."
I love this picture the best, by the way!

Book review of Mastering Zabbix by Packt Publishing

I would like to make a quick review about Mastering Zabbix by Packt Publishing because I recently read itto learn how to manage large environment with Zabbix.

Mastering ZabbixMastering Zabbix by Andrea Dalle Vacche

My rating: 4 of 5 stars

Mastering Zabbix is quite helpful for the beginners or the intermediate those who need to manage and monitor IT infrastructure especially for mission critical environment or with hundreds of nodes because it covers database-sizing, capacity planning, distributed monitoring, High availability and Failover, managing alerts and template, and integrating zabbix itself with the best practices of zabbix.
If you are facing with the trouble like handling hundreds of alerts which the nodes your zabbix monitors sent to you, your zabbix server's performance is getting worse as the infrastructure is growing, or generating SLA report to analyze and measure the operating ratio of the IT infrastructure, it should be worth reading and the solution for you with the practical examples.
I'm pretty sure that there will be definitely some those who don't need this book because they love zabbix or OSS monitoring solutions, and become enthusiastic about finding solution themselves. But, you will be able to reduce and save your time to soluve your issues by trying some of the solutions on this book.
Lastly, I like the 3rd chapter, High Availability and Failover, because it broadly covers the basic understanding of the levels of IT service, the common problems of HA architecture, and how to implement HA clustering of web server with corosync and pacemaker and clustering of PostgreSQL with DRBD on LVM, moreover DRBD performance and optimizations!
The problems is that it's written about Zabbix 2.0.0, not 2.2.0, so I hope that the book is revised for Zabbix 2.2 or later in the next version. But I recommend you should try to read "Mastering Zabbix" because nobody wants to carry the technical books with you everyday.
