Visible Challenges in Belize

− Bandwidth (Expensive)● ADSL 512Kb/s upstream

● (Average web page size for portal is around 500Kb)● Traffic burst (big files/ media streaming/ /concurrent access)● 2M/512K=250USD/month, 4M/1M=425USD/month● Unstable power caused randomly downtime about 4%

− Resources● Time, money, and people locally are always limited.● Hardware Maintenance● Reliable Storage● Reliable Electricity

Centralized and Decentralized

● Host Locally − Reliable storage $$− Database/System

Backup− Bandwidth $$$$$− Human resources

$$$$$− Performance − Traffic − Load Balancer $$

● Hosting on Other Countries

− Lower Cost− Better Quality− Better availability− Higher Bandwidth
