The Cloud is all around us.On your iPhone. Under your Facebook apps. All up in your twitter account.

8

The Cloud is the future.But, then again, you could say that about almost anything if you make its definition broad enough.

But it sounds too good to be true.

12

Making the most of it.

13

Secret Sauce

Don’t just deploy your applications on the cloud, write them for the cloud.

14

Secret Sauce, cntd.

Use best-fit cloud application services.

15

Cloud Application Services

S3

Azure Blob Storage

Rackspace Cloud Files

Unstructured Storage

16

Cloud Application Services

SimpleDB

Azure Table Storage

Quickbase

Google Datastore

Document Storage

17

Cloud Application Services

SQS

Azure Queue Storage

OnlineMQ

Simple Queues

18

Future Cloud Application Services

Authentication and Authorization

Session Management

Messaging

Scheduler

Search

Spam/Virus Detection

Analytics

And on. . .

And on. . .

19

Applications written for the cloud are. . .

More Performant

More Scalable

Better Designed

More Secure

Less Expensive

20

. . .assuming you chose the right cloud provider.

21

Now You’re ScrewedEvery API is different! I’m locked in! My cloud provider is bending me over! The sky is falling!

22

Or are you?After all, there’s lots of commonality across cloud application services.

23

Yes, you are.All that commonality is hidden behind uninteresting differences.

24

Porting an AWS Application to Azure

Change your signature algorithm

‘buckets’ are now ‘containers’

‘objects’ are now ‘blobs’

SQS RESTish query API needs to be changed to the RESTful Azure Queue Storage API

SimpleDB to Azure Table Storage? Good luck with that.

25

Moving Your Applications is HardAnd not for interesting reasons. :-/

Ummm. . .

29

Let’s not.

30

Open Source to the RescueIs there anything it can’t do?

31

Standards vs Open Source Bring a lot of minds

together to think about a problem

Intelligent design

Can stifle innovation

Sloooooooooooow

Can be abortive

Unenforceable

Brings a lot more minds together to think about a problem

Survival of the smartest

Encourages innovation

Slow

Can be abortive

Unenforceable

We can't change the server-side APIs, but we can change the client-side libraries.
