Google’s Ingenious Wave Security Model

Google Wave: You need to pay attention to this.

So here’s the deal with Wave:  If you deal in technology, and you get this one wrong, you’ll miss the boat.  And it’s a big boat.  If, on the other hand, you get this one right, you have the potential to do some incredible innovation.

In a nutshell, this is the next revolutionary leap in Internet application architecture.  Maybe the first truly revolutionary leap since HTTP itself.

I’ve been wanting to write this post for a while, but first I wanted to read fully thru and digest the specs and available code.  I haven’t done any posts about XMPP for quite a while, but you’re going to start hearing a whole lot about it, and not just from me.

What is it?

Ok so what exactly Google Wave is can be confusing, because there are three parts:  the protocol, the server, and the client.  A lot of people are really going to miss the boat here if they don’t keep the distinction between the three in mind, because I see a lot of people focusing on the wrong parts.

The Protocol

At its core, Wave is an extension to the XMPP protocol.  This is the REALLY important part.  Here I’ll back up for a moment for a little background on XMPP.  

XMPP is a protocol which describes communication.  It models communication between two nodes on a network.

Now, communication can take many forms, and XMPP accommodates many of them.  It also supports different types of conversations:  presence, notifications, subscriptions, back-and-forth–these are all modeled by XMPP.  And it supports a wide variety of communication TYPES as well:  video, audio, text, and so on.

I hear people mistakenly talking about Wave as immature or new technology.  It’s not.  XMPP has been around since 1998, being developed and actively worked on for almost 12 years now.  It’s been approved by the IETF since 2004.  

Although it’s been mostly used for chat, that’s only the tip of the iceberg when you dig into this protocol.  I’m still pretty flabbergasted that this protocol hasn’t been used more than it has, and I’m excited to see somebody finally tapping into its potential.

I’ll touch on what Google has brought to the table with the protocol in a minute, but suffice to say that if Wave takes off as I hope it will, the full power of the XMPP protocol will finally be available as a core piece of application architecture.  This is the real game-changer here, and what you need to be thinking about.

The Server

The server (a “wave provider”) is a modified Openfire XMPP server that understands the Wave protocol extensions.  Openfire has been around for a while too.

While wave providers are used for storing and server XMPP content in Google’s implementation, there is a lot of potential in turning existing applications into wave providers as well.  Any existing server-based content can be used as the basis for a wave, so just about any application out there right now has the potential to extend its existing functionality by offering its contents as waves.

The Client

Ok, this is probably what you’ve seen videos of.  It’s a wave client because it speaks wave protocol to wave providers.  

What Google has done is develop the first really full-featured XMPP client, which also uses some of their new XMPP extensions to facilitate things like character-by-character updates.  They’ve developed an incredibly sexy client, and I’m glad about it, because a sexy client like is what’s required to sell an innovation this large to both the mass market AND the technical community.

What Google has done, exactly?

So what exactly has Google done to the XMPP protocol?

A couple of things:

• It recognizes a conversation as data, and stores the data in a persistent way that can be easily referenced over time.  Conversation storage and persistence is a huge gaping hole in enterprises right now, which you’ll nod your head in agreement with if you’ve ever scoured a wiki for information or cleaned out your inbox because it got too big.
• It makes XMPP conversations secure and scalable.  By building in synchronization protocols, conversations can take place distributed across the network instead of at specific central servers (which is how wikis, blogs, and microblogs operate).
• It describes a way to replicate content over a large network so that it’s available on a wide scale while still being fast and synchronized.  Data replication on a global (but as-needed) scale, very cool. 
• It integrates a very simple and elegant security model which operates on an as-needed basis.  I’ve blogged about this in more detail before here. 

These were some needed additions to XMPP, and really describe some of the peer-to-peer operations that I’ve been looking for for a long time.

Why is this so interesting?

XMPP.  In case you haven’t noticed, I’m a big fan.

XMPP is so versatile that if it becomes widely adopted it will be to the Internet what HTTP was:  a platform for new types of applications.  And where HTTP as a platform is a server-centric model, XMPP is capable of peer-to-peer communication.

Remember what happened when everyone got HTTP clients (they’re called browsers ?  The Internet exploded.  Well, if everyone gets a full-fledged XMPP client I think you can expect roughly the same thing to happen.

One of the most fascinating features of XMPP is the way things are addressed.  EVERYTHING is addressable over the network. You can talk directly to ANYTHING, and ANYONE.  I can’t stress how big of a shift that would be from the current model.  It’s HUGE.  I wrote a whole series of posts on this a few years ago, and it’s just as exciting now as it was then.

Let’s take a step back and think about this for a second.  I’ll probably do another post just on the addressing scheme at some point because it’s so key, but it’s worth a brief recap.

• Right now I cannot send text directly to your instant message account (unless you’re using an XMPP-based client), I have to send the message to your IM server which relays the message to you.
• I cannot send audio directly to your phone, the phone company has to route it there. 
• I cannot share a picture directly with your Facebook account, I have to sent it to Facebook first to be carried on to you.  
• I can’t send a file directly to you, I have to put it on a share or email it to you. 

(Not to mention the fact that these are all disconnected, you can’t combine these into a single message stream.  XMPP addresses that problem very nicely, as the wave client shows.)

XMPP removes these intermediaries from the network.  Social networks and proprietary transports no longer have an exclusive license to deliver content, the clients talk directly to one another.

Do you see the difference?  There are no longer social networks or any other type of networks required to relay the communication, we are now down to exactly 3 components:

1. Clients 
2. Storage 
3. Applications 

Of course there is always the underlying dumb pipes that transport the data, but from a functional perspective the network has been normalized out of importance.

Clients can be whatever we need them to be.  It can be the Google wave client, it can be your phone, it can be a desktop app.  These will evolve over time, but the Google client is a fantastic starting point, certainly light years ahead of anything else that’s available today.

Storage becomes a utility, something you pay for as you go.  I already use this model myself for backups, I shoot them up to the Amazon cloud and pay for the amount I use.  As time goes on my communication–audio, video, pictures, text–will be stored there as well, and I’ll use it in my waves as needed.  (Note that waves do NOT embed this content, they link to it and the client downloads and renders it in place.)

And the applications.   This is really exciting, because just about every application in existence will be transformed by this quantum shift in the network topology.  Applications now interact with your client and provide input to your communication stream, and output to your storage.  They will become a facet of your communication, not a completely disconnected activity.  You will communicate with apps much in the same way that you communicate with people, and they will communicate with you.

Take CRM and ERP systems for example.  Instead of customers emailing you about a sale and then sending purchase orders, it will be part of the “sale wave”.  The entire sale, from start to finish, will be encapsulated in a single wave, bringing individuals in and out of the conversation as need.  The ERP and CRM platforms themselves will be participants in this conversation, recognizing the purchase order, executing the workflow, processing the order, making the order details available to manufacturing or delivery in a sub-wave, and then making the receipt available to the customer and the sales team.  Your CRM Whether you approve the purchase order from your desktop, your phone, or a point of sale device, makes no difference–they can all be directly addressed and participate in the conversation natively.

That’s just one example off the top of my head, but I truly believe that every software application in existence will eventually need to be re-architected to be much less application-centric and much more communication-centric.

The Bottom Line

This is no longer pie-in-the-sky stuff like it was when I was first writing about it.

I have seen nothing else out there that rivals the XMPP/Wave protocol for the sheer richness of the conversation that’s possible, not to mention the fact that it can easily turn into a bona-fide platform for next-generation applications.

The danger, then, is that you ignore this and it takes off.  You and your application will be shut out of this rich, real-time collaborative stream of communication.  You can, of course, tack integration on later, but the real benefit here is to the application that incorporates these concepts into its core architecture.  I can look at just about any application out there and think of tons of potential applications for this technology.

This is the type of revolutionary advance that is required to lift productivity and open brand new possibilities to the extent necessary to revive the economy, which is pretty exciting.  If this post sounds like I’m breathlessly waiting for this technology to take off, it’s because I am, and I have been for about 3 years now.  Here’s hoping Google succeeds.

Google continues to evolve open standards and build amazing UI around them. If you don’t think WAVE will be a game changer then you need to take a second look at the type of real time communication it enables. In addition think about the younger workforce. They “only” use txt messages and chat as forms of communication. Email is dead for them and they don’t even know what voicemail is. Google is building a collaboration platform for the up and coming workforce of tomorrow…

AT&T customers who live or work in one of the company’s many pockets of poor or dead 3G service will soon have the option to pay $20 extra to obtain unlimited calling over 3G using their own Internet access.

AT&T hasn’t yet set a retail price on its forthcoming new 3G MicroCell appliance, which connects to your existing Internet to supply local 3G voice, SMS/MMS, and data coverage for nearby AT&T customers. However, a report by Engadget Mobile attributed to an anonymous tipster says that the company plans to offer an unlimited calling plan for users for $20 per month.

For $20 I would pay to have excellent connectivity in my home from our two iPhones.

Amazing video from XPLANE showing the advancement in mobile technology and digital media. You will be shocked by the facts.

Ya the biggest grief is created by the “require encryption on the device” setting which blocks all iPhones before the 3GS from syncing. The 3GS is the first and only iPhone with storage encryption capability.

If you love the action puzzle game genre (think Orbital) then you must try ‘Stay” by Anthropophagy. Watch the video to see the gameplay. It is surprisingly difficult and full of strategy.

Amazing new set of vinyl skins for Mac laptops. Very nice.

Understanding that these single-payer health programs are already a major part of our overall health care system should help us visualize what an actual public plan would look like. These institutions also provide health care to millions of satisfied customers in every community who would heartily agree that the government can build and run programs that work quite well.

Well said Rep Weiner…. well said.
