Introduction to Amazon Web Services (EC2)

Introduction to Amazon Web Services EC2 In Particular Nathan Powell, Consultant Tangeis, LLC http://tangeis.com (but we are changing our name soon)

What are AWS?

Various web application components

Simple DB

S3

Simple Queue Service

EC2

All accessible via APIs

Explain EC2.

EC2 is the Elastic Compute Cloud

It is physical hardware

Pwnd and operated by Amazon

Virtual servers

Self aware API

Grow and Shrink

Uh huh, how's that work?

Xen Images/AMI's

Disk images of functional servers

Create your own, or customize public images

Save off/Upload image (to S3)

Spin up/down instances to handle needs

Interesting. What are some uses?

Spin up a large number of instances churn a ton of data spin back down

No need to build/buy

No need to wait

Create self scaling web apps

Few applications are always busy

Cost prohibitive to be prepared for anything

Testing

R&D is now much much cheaper

Ok, cool...tell me more

Root access to all instances

Multiple Locations

Reduce Geo-Failover costs

Content Delivery Network

Web service interface to firewall in the cloud

Eliminates Wasted Resources

Drawbacks?

Instance storage not persistent

That is changing very soon

In beta now

Dynamic IP

This just ended

Now the IP is associated with account, not instance

Can programatically map IP to any instance

Good use for LB/VRRP? [citation needed]

Anything else?

It's important to note that it introduces changes in how we build and deploy and think about applications and infrustructure.

AWS goes together

S3 (Simple Storage Service)

Simple DB

SQS (Simple Queue Service)

Dev Pay

Mechanical Turk

There is no free lunch

$0.10 - Small Instance (Default)

1.7 GB of memory, 1 virtual core, 160 GB of instance storage, 32-bit platform

$0.40 - Large Instance

7.5 GB of memory, 2 virtual cores, 850 GB of instance storage, 64-bit platform

$0.80 - Extra Large Instance

15 GB of memory, 4 virtual cores, 1690 GB of instance storage, 64-bit platform

And there's more!

$0.100 per GB - all data transfer in

$0.170 per GB - first 10 TB / month data transfer out

$0.130 per GB - next 40 TB / month data transfer out

$0.110 per GB - next 100 TB / month data transfer out

$0.100 per GB - data transfer out / month over 150 TB

Ok, this is starting to suck, show us something...anything?!?

Psst, stop showing slides and move over to the demo side...that is where this stuff really starts to rock. (Make sure you take this out before the presentation and put a picture of a pony here a really pretty one...maybe on a beach or something. Ooo! I know show some girls, these nerds have probably never seen girls close up, they will really really like that!)
