Scalability Perspectives #5: Werner Vogels – The Amazon Technology Platform

DateTuesday, December 30, 2008 at 1:07AM

Scalability Perspectives is a series of posts that highlights the ideas that will shape the next decade of IT architecture. Each post is dedicated to a thought leader of the information age and his vision of the future. Be warned though – the journey into the minds and perspectives of these people requires an open mind.

Werner Vogels

Dr. Werner Vogels is Vice President & Chief Technology Officer at Amazon.com where he is responsible for driving the company’s technology vision, which is to continuously enhance the innovation on behalf of Amazon’s customers at a global scale. Prior to joining Amazon, he worked as a researcher at Cornell University where he was a principal investigator in several research projects that target the scalability and robustness of mission-critical enterprise computing systems. He is regarded as one of the world's top experts on ultra-scalable systems and he uses his weblog to educate the community about issues such as eventual consistency. Information Week recently recognized Vogels for this educational and promotional role in Cloud Computing with the 2008 CIO/CTO of the Year award.

Service-Oriented Architecture, Utility Computing and Internet Level 3 Platform in practice

Amazon has built a loosely coupled service-oriented architecture on an inter-planetary scale. They are the pioneers of Utility Computing and Internet Platforms discussed earlier in Scalability Perspectives. Amazon's CTO, Werner Vogels is undoubtedly a thought leader for the coming age of cloud computing.

Cloud Computing CTO or Chief Cloud Officer?

Vogels' name and face are often associated with Amazon's cloud, but Amazon Web Services isn't a one-man show, it is Teamwork. Amazon's CTO has emerged as the right person at the right time and place to guide cloud computing - until now, an emerging technology for early adopters - into the mainstream. He not only understands how to architect a global computing cloud consisting of tens of thousands of servers, but also how to engage CTOs, CIOs, and other professionals at customer companies in a discussion of how that architecture could potentially change the way they approach IT. If all goes as planned, Amazon's cloud will serve as an extension of corporate data centers for new applications and overflow capacity, so-called cloud bursting. Over time, Amazon will then take on more and more of the IT workload from businesses that see value in the model. Customer-centric? What Amazon's doing goes beyond that. Amazon's cloud becomes their cloud; its CTO, their CTO. As an expert of distributed systems Vogels shares interesting insights on scalability related issues on his blog such as:

The Amazon Technology Platform

Werner Vogels explains how Amazon has become a platform provider, and how an increasing number of diverse businesses are built on the Amazon.com platform in this QCon presentation. The most important thing to understand is that Amazon is a Technology Platform with the emphasis on Technology. The scalable and reliable platform is the main enabler of Amazon's business model. Dr Werner describes Amazon’s platform business model and its ‘flywheel’ for growth on the latest episode of the Telco 2.0 ‘executive brainstorm’ series on Telecom TV. Amazon has many platforms that fuels growth such as:
  • Amazon Merchants
  • Amazon Associates
  • Amazon E-Commerce Platform
  • Web Scale Computing Platform
  • Amazon Kindle
  • Telecommunications platfrom using Amazon's platform?
Werner provides interesting insights about these platforms in his presentation. Check out his blog and other resources to learn more about his vision and Amazon's future.

Scalability Perspectives #3: Marc Andreessen – Internet Platforms

DateMonday, November 24, 2008 at 3:09AM

Scalability Perspectives is a series of posts that highlights the ideas that will shape the next decade of IT architecture. Each post is dedicated to a thought leader of the information age and his vision of the future. Be warned though – the journey into the minds and perspectives of these people requires an open mind.

Marc Andreessen

Marc Andreessen is known as an internet pioneer, entrepreneur, investor, startup coach, blogger, and a multi-millionaire software engineer best known as co-author of Mosaic, the first widely-used web browser, and founder of Netscape Communications Corporation. He was the chair of Opsware, a software company he founded originally as Loudcloud, when it was acquired by Hewlett-Packard. He is also a co-founder of Ning, a company which provides a platform for social-networking websites. He has recently joined the Board of Directors of Facebook and eBay.

Marc is an investor in several startups including Digg, Metaplace, Plazes, Qik, and Twitter. His passion is to create new technologies, to start new companies, and to scale them up.

Internet Platforms Rule the Cloud

From Marc's Blog Post on the Three Kinds of Platforms:

One of the hottest of hot topics these days is the topic of Internet platforms, or platforms on the Internet. However, the concept of "platform" is also the focus of a swirling vortex of confusion -- lots of platform-related concepts, many of them highly technical, bleeding together; lots of people harboring various incompatible mental images of what's about to happen in our industry as a consequence of various platforms. I think this confusion is due in part to the term "platform" being overloaded and being used to mean many different things, and in part because there truly are a lot of moving parts at play that intersect in fascinating but complex ways.

Marc attempts to disentangle and examine the topic of "Internet platform" in detail. He has identified three distinct approaches to providing an Internet platform and shows us where each of the three approaches could go.

Internet Platforms Defined

A "platform" is a system that can be programmed and therefore customized by outside developers -- users -- and in that way, adapted to countless needs and niches that the platform's original developers could not have possibly contemplated, much less had time to accommodate.
...
The key term in the definition of platform is "programmed". If you can program it, then it's a platform. If you can't, then it's not.

The Internet gives rise to three new models of platform that is playing out in the Internet industry today. Marc calls these Internet platform models "levels", because as you go from Level 1 to Level 2 to Level 3, each kind of platform is harder to build, but much better for the developer. Further, each level typically supersets the levels below.

Level 1 Platform - "Access API"

This is the kind of Internet platform that is most common today. This is typically a platform provided in the form of a web services API -- which will typically be accessed using an access protocol such as REST or SOAP.

Architecturally, the key thing to understand about this kind of platform is that the developer's application code lives outside the platform -- the code executes somewhere else, on a server elsewhere on the Internet that is provided by the developer.

Examples: eBay, Paypal, Flickr, Delicious

  • The entire burden of building and running the application itself is left entirely to the developer
  • The easiest kind of Internet platform to create

Level 2 Platform - "Plug-In API"

This is the kind of platform approach that historically has been used in end-user applications to let developers build new functions that can be injected, or "plug in", to the core system and its user interface.

In the Internet realm, the first Level 2 platform that I'm aware of is the Facebook platform.

When you develop a Facebook app, you are not developing an app that simply draws on data or services from Facebook, as you would with a Level 1 platform. Instead, you are building an app that acts like a "plug-in" into Facebook -- your app literally shows up within the Facebook user experience, often as a box in the middle of a page that Facebook otherwise defines, such as a user profile page.

  • The third-party app itself lives outside the platform
  • The entire burden of building and running a Level 2 platform-based app is left entirely to the developer
  • Unlike a Level 1 platform where the burden of exposing the app to users is also placed on the developer, Level 2 Internet platforms -- as demonstrated by Facebook -- will be able to directly help their developers get users for their apps
  • Level 2 platforms are significantly harder to create than Level 1 platforms

Level 3 Platform - "Runtime Environment"

In a Level 3 platform, the huge difference is that the third-party application code actually runs inside the platform -- developer code is uploaded and runs online, inside the core system. For this reason, in casual conversation I refer to Level 3 platforms as "online platforms".

In addition, it is highly likely that a Level 3 platform will also superset Level 2 and Level 1 -- i.e., a Level 3 platform will typically also have some kind of plug-in API and some kind of access API.

Put in plain English? A Level 3 platform's developers upload their code into the platform itself, which is where that code runs. As a developer on a Level 3 platform, you don't need your own servers, your own storage, your own database, your own bandwidth, nothing... in fact, often, all you will really need is a browser. The platform itself handles everything required to run your application on your behalf.

Obviously this is a huge difference from Level 2. And this difference -- and what makes it possible -- is why I think Level 3 platforms are the future.

  • Level 3 platforms are much harder to build than Level 2 platforms.
  • The level of technical expertise required of someone to develop on your platform drops by at least 90%, and the level of money they need drops to $0
  • The Level 3 Internet platform approach is much more like the computer industry's typical platform (PC) model than Levels 2 or 1.

Who is building Level 3 Internet platforms?

Marc has built one - Ning has been built from the start to be a Level 3 platform.

Other Level 3 platforms include:

How will we see the new platforms of the future?

We are used to seeing platforms ship as products -- you buy and install a PC or a server and you build an app that runs on it, or equivalently you download and install an open source platform such as Perl or Ruby and you build an app that runs on it.

The platforms of the future won't be like that. The platforms of the future will be online services that you will tap into over the Internet, perhaps with nothing more running locally than a browser. They won't have anything you download, or even an SDK. They will look more like services than software. To paraphrase the Book of Matthew, "you will know them by their URLs".
