PHP and Platform Independance in the Cloud

PHP and Platform Independence in the Cloud
ByWil Sinclair – Cloud Zealot

What is the Cloud?
And why can’t we all move on to the next big thing already?

Cloud:Tools::Internet:Content

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

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

Select Benefits
Elasticity
Scalability
High Availability
Resilience
Location Independence
Development Best Practices
Security

But it sounds too good to be true.

Making the most of it.

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

Secret Sauce, cntd.
Use best-fit cloud application services.

Cloud Application Services
Unstructured Storage
S3
Azure Blob Storage
Rackspace Cloud Files

Document Storage
SimpleDB
Azure Table Storage
Quickbase
Google Datastore

Simple Queues
SQS
Azure Queue Storage
OnlineMQ

Future Cloud Application Services
Authentication and Authorization
Session Management
Messaging
Scheduler
Search
Spam/Virus Detection
Analytics
And on. . .
And on. . .

Applications written for the cloud are. . .
More Performant
More Scalable
Better Designed
More Secure
Less Expensive

. . .assuming you chose the right cloud provider.

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

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

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

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.

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

Let's Open Up a Can of Standards on these APIs!

Ummm. . .

Let’s not.

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

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

The PHPilosophy
Start with Something You Can Change
We can't change the server-side APIs, but we can change the client-side libraries.

The PHPilosophy
Build on What's Already There

The PHPilosophy
Wave the magic wand of abstraction. . .

The PHPilosophy
Until You Have Something That's Useful

Repeat until you have something that's taken on a life of its own.

You knew it was coming. . .
