What we will talk about...
● What is a cloud and why it doesn't in a sky
● Three types of cloud
● You can try it free!
What is a cloud and why it doesn't in a sky
Definition of Cloud
● Self service on demand
● Scalability and elasticity
● Multitenancy
● Only used resources are counted
What is scaling?
It is linear relationship betweenmoney and productivity!
Scale vertically vs. horizontally
Under the hoodMicro
● 1-2 EC2 Compute Units*
● 613 MiB of memory
● EBS storage only
● $0.020 per Hour
Quadruple
● 26 EC2 Compute Units*
● 68.4 Gib of memory
● 1690 GB of storage
● $3.100 per Hour
*EC2 Compute Unit ≈ 1.7 GHz Xeon
1 Quadruple for $3.100 = 155 Micro for $0.020
Sometimes it worth of it!
Three types of clouds
● IaaS (Infrastructure as a Service)
Amazon EC2
● PaaS (Platform as a Service)
Jelastic, Google App Engine, Windows Azure
● SaaS (Software as a Service)
GMail, Google Docs
Amazon Web Services (AWS)
Some really cool free stuff
Benefits and cons
● Less work for system administrator, but may
require special skills from him.
● You don't need to think about hardware.
● You can buy large amount of especially
prepared resources even for few hours.
● (Private) data is stored in unknown place.
● Instance is not immediately available.
● Hourly payment is invisible.
