notes:
[16'10/2]:
  - LAMP is not feasible due to security concern. Ex: DoS,
  - solution w/ security communication : SSL/TLS
   - Encrypt : AES, DES, CRC, SHA, MD5 
  -  MCU w/ security module : PIC32MZ EC (Microchip Technology)  , Tiva C (Texas Instruments) 
   - SQI is flash interface w/ 4 IO could have 4 times speed than SPI. No mater 1,2,4 line communication, they are still half-duplex instead of full-duplex
   - IAAS/PAAS provider : Amazon, Salesforce, Microsoft, IBM, Google, Fujitsu, NTT, AT&T, Verizon, Deutsche Telekom

...etc.

TODO:
[16'10/2]:
  - keep to track solution w/ security & account management.

Hadoop

Commetns:
- distributed architecture for compunting & storage
- could run in 3 modes : standalone , pseudo districuted, fully distributed
- client-server architect :
Server : run Name Node + Job Tracker
Client : run Data Node + Task Tracker
- the execution liverage counts on : MapReduce which is executed in slave side
-  HDFS is the filesystem used in hardoop, it will be kept in 3 different place. 2 is near-end side and the other is in far-end side
- HBASE is like a database could use for saving data after Reduce

Thinking:
- if our traget data is distributed everywhere, maybe it's a way to handle locally and migrate.
- the point is map & key, the application must be divided & indexed via a key.
