I quite confuse about VMware Product Name between vCloud and vRelized. VMware renamed the product on VMWorld 2014. Here's the summary of VMware Product.

ช่วง 5 ปีให้หลังจะได้ยินคำว่า DR Site (Disaster Recovery Site) บ่อยมาก และเริ่มมีบริษัทสนใจที่จะ implement DR Site หลังจากช่วงกีฬาสีและช่วงน้ำท่วม แต่ยังไม่รู้ว่า DR Site ควรจะต้องทำยังไง และต้องทำอะไรบ้าง ใน Entry นี้จึงอธิบายวิธีการกันก่อน

จะมี 3 คำที่ต้องคุ้นเคยก่อน

• Disaster Recovery
• Business Continuity 
• Disaster Recovery / Business Continuity Plan

Disaster Recovery

• เป้าหมาย เพื่อฟื้นฟู Business Process ที่วิกฤติ ที่ทำให้การดำเนินการธุรกิจหยุดชะงัก เช่น ERP 
• Disaster Recovery เป็นส่วนหนึ่งของ Business Continuity
• โฟกัสไปที่ Data Recovery
• ช่วงเวลาการฟื้นฟู ไม่เกิน 30 วัน
• Solution : Hot Site Recovery

Business Continuity 

• เป้าหมาย เพื่อฟื้นฟูธุรกิจให้กลับเป็นสถานะเดิม เช่น การทำงาน, process (คือเคยทำงานแบบใด ก็ทำงานแบบปกติ)
• โฟกัสไปที่ การทำให้เป็นปกติ
• ช่วงเวลาการฟื้นฟู 30 วันเป็นต้นไป
• Solution : New Building, New Device

Disaster Recovery / Business Continuity Plan

• เป็น วิธีการ, Process, กระบวนการ ที่ทำให้เกิดความสูญเสียให้น้อยที่สุด 
• เป็น Guideline หรือกิจกรรมที่ต้องทำในการฟื้นฟู
• เขียน Test Plan ที่ทำให้การฟื้นฟูเป็นไปตามเวลาที่กำหนดไว้ 

I have heard docker for long time. Today I listen presentation, then try to setup docker in OS X environment. Here's the step of installation.

1. Download Boot2Docker, then install pkg
2. Open Boot2Docker in Application
   

   bash
   unset DYLD_LIBRARY_PATH ; unset LD_LIBRARY_PATH
   mkdir -p ~/.boot2docker
   if [ ! -f ~/.boot2docker/boot2docker.iso ]; then cp /usr/local/share/boot2docker/boot2docker.iso ~/.boot2docker/ ; fi
   /usr/local/bin/boot2docker init 
   /usr/local/bin/boot2docker up 
   $(/usr/local/bin/boot2docker shellinit)
   docker version

3. You may download image from Docker's repository by using this command
   

    docker pull centos:7

4. Try to run "docker run hello-world"
   

   bash-3.2$ docker run hello-world
   Hello from Docker.
   This message shows that your installation appears to be working correctly.
   
   To generate this message, Docker took the following steps:
    1. The Docker client contacted the Docker daemon.
    2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
       (Assuming it was not already locally available.)
    3. The Docker daemon created a new container from that image which runs the
       executable that produces the output you are currently reading.
    4. The Docker daemon streamed that output to the Docker client, which sent it
       to your terminal.
   
   To try something more ambitious, you can run an Ubuntu container with:
    $ docker run -it ubuntu bash

I just know that Docker built in GO

vSphere Replication

• VR Traffic can be isolated from other vSphere host traffic

• Uses FastLZ compression llibraries

VMware vCenter 6.0

• Microsoft clustering support, not just the database
• Fault Tolerance is not supported for vCenter Server on Windows and the vCenter appliance
• vMotion across vCenter. Requires vSphere 6.0 on both ends
• Long distance vMotion increased latency supports up to 100ms RTTs
• Windows install supports Postgres and External SQL and Oracle DBs
• vCSA supports embedded Postgres and external Oracle DBs

VMware VM Component Protection (VMCP)

Imagin fiber channel controller failure, VMware HA is now able to detect the loss of storage connection and restart virtual machine on other hosts

Others:

• Edition Comparison
• vCenter Server
• Certification Roadmap

Flickr is the best tool for backing up photos. The one of Flickr's problems is, it's very difficult to view overall photos. When I would like to find them without searching, I have to click each page. It takes time so much. I just see that Flickr releases Camera Roll. I love this feature so much because I can view overall photos with small thumbnail. So I can find photos quickly.

I have not seen new feature for long time. I hope flickr will release many features later.
