Time to Define "Platform as a Service" (or PaaS)

alexbarnett — Tue, 19 Feb 2008 09:27:00 GMT

Before joining Bungee Labs last year, I knew they were on to something big. I mean, really big.

A big idea, an ambitious vision: to provide developers with end-to-end development, testing, deployment and hosting of sophisticated web applications as a service delivered purely in the cloud.

Since we announced our private beta back in May 2007, we've had over 1,500 developers sign up. In January alone we had over 400 developers kicking the tires - not just signing up and disappearing, but 400 returning developers, learning, building and deploying out increasingly sophisticated apps on a fast evolving developer platform, requiring no install of anything on their machine - all through the browser.

And since May 2007, the trend to delivering software as a service (SaaS) has been moving at terrific pace. New web APIs are being made available every month and new announcements by start-ups as well established big players are reinforcing and fueling the acceleration to the inevitable world of cloud computing.

As we announce our move from private to public beta today, we've also tried to articulate the new category of product and service we believe Bungee Connect is at the forefront of defining, the category of Platform as a Service, or PaaS, and our big bet is that PaaS is the next big thing.

So what is a "Platform as a Service"?

In September 2006, Marc Andreessen posted his thought provoking "The three kinds of platforms you meet on the Internet" and it got a fair level attention from the web industry. And we took note. We thought what Marc was describing in his Level 3 definition where:

"A Level 3 platform's apps run inside the platform itself -- the platform provides the "runtime environment" within which the app's code runs.",

...was right, but only partly right. Given Bungee Labs' ambition and vision, we felt there was a lot more to Marc's definition of the highest level definition of an "internet platform", a definition more holistic and comprehensive than a runtime.

But we kept focused, kept working on what we were hearing our developers telling us we needed to fix and improve on Bungee Connect, to give what developers are telling us what they really want - a Platform as a Service - to provide everything required in the lifecycle for the development through hosting of full-on, sophisticated and highly interactive web apps, not just widgets.

As we were readying for our next phase -our public beta - we thought it would be a good time to put a stake in the ground and actually define what we mean when we use the term Platform-as-a-service, and thereby describe the comprehensiveness what Bungee Connect has to offer.

So early this morning, our CTO and Founder of Bungee Labs, Dave Mitchell posted a definition describing PaaS in concrete terms.

What follows is a summary of Dave's post, with a selection of my favorite "soundbites" and ideas, but I suggest you read the whole post for yourself - there's a fair amount to consider:

1) Develop, Test, Deploy, Host and Maintain on the Same Integrated Environment.

"It’s time to stop developing “here” and running “there”. Today, most applications are coded in one environment (usually custom-built for that project by a developer), then tested in another, and redeployed to yet another for production...In a completely-realized PaaS, the entire software lifecycle is supported on the same computing environment, dramatically reducing costs of development and maintenance, time-to-market and project risk. A PaaS should let developers spend their time creating great software, rather than building environments and wrestling with configurations just to make their applications run — let alone testing, tuning and debugging them...Also, an end-to-end PaaS should provide a high productivity Integrated Development Environment (IDE) running on the actual target delivery platform, so that debugging and test scenarios run in the same environment as production deployment.

2) User Experience Without Compromise

"A Platform-as-a-Service must deliver compelling user experiences, with all the richness and live interactivity that consumers have been conditioned to expect....Hiccups like software downloads or plug-in installations, browser dependencies and inconsistencies, or local executables break the web model, and are inherently less secure, less maintainable and less user-friendly. In order to be relevant and popular, PaaS must deliver the best user experience available on the web, comparable to or better than conventional approaches.

3) Built-in Scalability, Reliability, and Security

"Developers should be free to build applications with the comfort that the security of customer data, network traffic, source code (intellectual property) and even server hardware is maintained automatically by the platform through-out application development and delivery."

4) Built-in Integration with Web Services and Databases.

"Applications need to leverage existing software investments in databases, and internal or external third party web services, requiring that the platform offer a wide variety of connectivity options."

5) Support Collaboration

"A PaaS must support both formal and on-demand collaboration throughout the entire software lifecycle (development, testing, documentation and operations), while maintaining security of source code and associated intellectual property."

6) Deep Application Instrumentation

"With instrumentation, organizations can see exactly how users are using the application, the type of performance they are experiencing and any application crashes. This information can also be leveraged to create new business models where costs are tied to actual utilities, rather than flat-rate subscriptions or licenses."

Over the next couple of years we expect to be hearing a lot more about PaaS and how "Y announcement" by "X company" is now providing true a PaaS offering to businesses and developers.

But saying you are providing a Platform as a Service has to mean something, and we think the above definition sets a high but reasonable standard that must be met for any company to claim they are providing a "platform-as-a-service' and legitimately describe themselves as a PaaS player.

The amazing thing is, for me at least, is that Bungee Connect is delivering all of the above, today. From our point of view, delivering PaaS - the real deal - is not statement of Bungee's intent, it's a statement of fact. It's bold, but so is our vision. Yes, we've still a lot to do before we're commercially ready and we think that's coming soon, but so much is already there. Try it out.

Podcast interviews - smart people in the world of the web

alexbarnett — Sun, 20 Jan 2008 15:41:00 GMT

One of the fun parts of my job at Bungee Labs is to partner up with Ted and interview some smart people in the world of the web. We publish these as a podcast series (the Bungee Line - podcast feed here) over on the BCDN blog.

If you have ideas about someone you think we should interview, let me know! We're focusing on topics we think web developers might be interested in the worlds of software as a service and web app development, in particular profiling web apis. Related topics are good too.

I've listed out below our most recent podcasts below...plenty more in the works (previous podcasts are listed here). Hope you like :-)

Alan Lewis on eBay Desktop and eBay APIs

"As product manager for eBay Desktop, Alan Lewis relies on the same web APIs that eBay makes available to all developers. In this edition of the Bungee Line, Alan tells us about what the eBay Desktop is, how it came about, and various details about eBay’s developer program and web APIs. We ask Alan about eBay’s position Oauth and on open source."

Toby Segaran on “Programming Collective Intelligence”

"Since the publication of his O’Reilly book Programming Collective Intelligence: Building Smart Web 2.0 Applications, Toby Segaran has become well noted for his ability to explain easily-understandable algorithms for the kind of deeply complex problems involved in social applications. Toby joins Alex and Ted to discuss some of the high-level concepts that he tackles in his book."

Jon Aizen of Dapper.net

"Jon Aizen joins Alex and Ted to explain how Dapper.net provides a no-fee tool for making almost any structured web site data accessible via a REST API. In a past life, Jon was involved in creating The Internet Archive. Jon also helps the Bungee Line introduce romantic intrigue into the podcast.

Punditry Alert! At the end of this show, Ted and Alex speculate a bit about Android, Google’s open source mobile device platform, the Apache License, and whether Robert Love is involved. Please consider this as another demonstration of Ted’s idiocy, brought to you by the Bungee Line."

Jeff Barr on Amazon Web Services (Part 2)

"In part 2 of our interview with Amazon Web Services evangelist Jeff Barr, Alex and Ted ask Jeff about Flexible Payment Service, virtual user group meetings in Second Life, the Startup Project, and pry at Jeff’s views of possible futures of technologies that developers might anticipate."

Jeff Barr on Amazon Web Services (Part 1)

"Developer evangelist for Amazon Web Services, Jeff Barr tells Alex and Ted about how he became a native Amazonian, his recent visit to “The Business of API’s Conference,” and a bunch of stuff on Amazon Web Services, including: Mechanical Turk, EC2, and S3. Additionally, Jeff explains the newly announced S3 Service Level Agreement*."

Ozzie's "Cloud OS" Raises More Questions than Answers

alexbarnett — Fri, 27 Jul 2007 20:04:00 GMT

Ray Ozzie's briefing this week provided quite a bit more detail around Microsoft's "Software Plus Services" strategy. It's definitely worth a read (or a look, and if you're feeling too lazy for either you can read Nick Carr's summary).

It's been a year since Ozzie took over the role as Chief Software Architect from Bill Gates, and I think it is exciting to see his influence further emerge throughout the business, architectural and experential direction of Microsoft. The 30 year old company needs this injection - a shot in the arm. And his vision is the right one. It is the only one that has any chance of seeing Microsoft through its need for growth.

However, as the Ozzie's "Cloud OS" story slowly becomes more concrete, the future influence that Microsoft will have throughout the software and internet services ecosystem is becoming less clear.

Yes, we know Software as a Service (Saas) is becoming an increasingly significant trend, and we know that the enabling role Web Services (SOAP and REST based) has to play as part of the overall move to a distributed computing model is becoming ever more central, and we know that the browser will continue to further its dominance as the primary interface between humans and data, functionality and people, but what is not so clear is how many "major players" there will be in that future, what their roles will be, nor what the roles of the "everyone elses" will be.

Microsoft Partners have been assured a place by Microsoft's side in this future, but does anyone really know? How will all this fall out? How will Microsoft's traditional partner profile fit into Ozzie's new brave future? What kind of ecosystems will emerge? Will Microsoft's ecosystem of tomorrow look radically different to its ecosystem of today? Who are the Microsoft partners of today who will find themselves competing head-to-head with Microsoft tomorrow? What will Microsoft's competition of the future even look like?

The answers to some of these question may surprise us. How many people, for example, would have imagined a just few years ago that search engine providers or an online bookseller or online university network would emerge to become a serious potential competitor in the computing and software space of Microsoft? Not many. In the second internet age Microsoft's future competition and partners can literally come from any direction at any time. And they often do. In many respects, the future looks bright, but I suspect that for many in the software / computing industry the future is also very cloudy indeed.

Announcing Bungee Connect

alexbarnett — Mon, 16 Apr 2007 07:11:00 GMT

At last, I can tell you more about what Bungee Labs has been up to...

We've just announced details about Bungee Connect, a 100% on-demand web development and deployment environment that will be going into Beta phase in May.

Over the next three days at the Web 2.0 Expo 2007 and on bungeeconnect.com we'll be providing a lot more detail on exactly what Bungee Connect is, how it works and why we think it will be a big deal when we go live.

So before I go on, let me quote a couple of people who have already seen Bungee Connect in action behind closed doors. The following are from tonight's two press releases (1 and 2)

First off, Dion Hinchcliffe:

“Ajax is just the beginning of the RIA story and Bungee Labs provides the rest of the solution with a web-based IDE, on-demand scalable deployment, a well-designed community model and a built-in component ecosystem with real-world licensing options,” said Dion Hinchcliffe, ZDNet blogger; President/CTO, Hinchcliffe & Co.; and editor in chief, AjaxWorld Magazine. “Bungee Connect is a surprisingly complete one-stop shop for the RIA development, deployment and operations lifecycle.”

Next, Dana Gardner:

“Given the current disjointed state of tools, testing and deployment models, most developers find creating rich internet applications (RIAs) to be complex, time-consuming and expensive,” said Dana Gardner, Principal Analyst, Interarbor Solutions. “By combining development, testing and deployment functions into an integrated, low-cost-of-entry service approach, Bungee Connect both broadens the numbers of developers that can produce web applications as well as slashes the barriers of entry for creating innovative ecommerce services and web-based businesses."

The Bungee Labs team has been working very closely with the Amazon team (and others API providers) the last few months to make sure Amazon's web services "just work" with Bungee Connect. Jeff Barr, Senior Evangelist for Amazon's Web Services:

“Bungee Labs’ decision to make their development environment integrate seamlessly with Amazon Web Services is great news for our developer community,” said Jeff Barr, Senior Evangelist for Amazon Web Services. “AWS developers can now use Bungee Connect to directly access our services, which means they can build Web-Scale applications in an easy to use, browser-based development environment.”

Another provider of web APIs, Salesforce.com has also been working closely with the Bungee Labs engineers. This time a quote from Adam Gross, Vice President, Developer Marketing, Salesforce.com:

“Salesforce.com has demonstrated that the innovation and ideas of the consumer Internet are at the core of the next generation of business applications. Bungee Connect together with Salesforce.com’s Apex platform makes it easier for developers to create mashups for their businesses, and in doing so hastens the transition from traditional enterprise software to the new on-demand model of building and deploying applications.”

So, what is Bungee Connect? Well, it's a lot of things:

Bungee Connect is a completely web-based integrated development environment (IDE) for building and deploying rich Ajax web applications, from simple web apps to seriously sophisticated Ajax applications. No install for developers, no installation of delivery infrastructure, and no client install for end users.
Bungee Connect is for developers, not for consumers. Yes, it provides a huge amount of automated support for the integration of SOAP and REST-based web services, Ajax app development and state management. You can develop sophisticated apps that integrate powerful (as well as simple) web services plus develop your own logic without having to write a line of code. It massivley reduces complexity. But, nonetheless, it is for developers, not consumers.
Bungee Connect provides a completely integrated means of deploying apps to the live web. No FTP. No separation between your dev, staging, production and live environment. No local set-up on your machine. No bits to install anywhere. No web servers, no app servers, no stacks, nor libraries to install, patch or manage. No 'Yak shaving'. It's all taken care of for you. You develop your app through the browser, then deploy your app through the browser and map the app to your domain / URL (or embed the app in your site) - It's your app. Oh, and you get IE, Firefox and Safari cross-browser compat taken care of too - you build your app once and it just works in these three browsers. Sweet.
Bungee Connect includes a whole code share and team collaboration concept. You can keep your code proprietary, or you can share it with other Bungee Connect developers in your workgroup or with the wider Bungee Connect developer community. There's a lot more to this than I can cover here and I'll be writing a lot more on this soon, but I like how Mat Asay described the community aspect as a 'Sourceforge for the 21st Century'.
Bungee Connect allows developers to leverage the world of web APIs. We've been working with the API engineering and evangelist teams at Amazon, Ebay, Google, Microsoft Windows Live, PayPal, RealNetworks, Salesforce.com and Yahoo! to ensure Bungee Connect works sweetly with the multitude of their rich APIs (both WS* and RESTful). The aim is to ensure Bungee Connect can work with any web service that you choose and by working with these teams and their APIs in developing Bungee Connect, we've got a great test-bed to make sure we can achieve this goal.
Bungee Connect is No Fee for the developer to use in developing and testing Bungee-powered apps. You only pay once you've deployed your app commercially or unrestricted. We expect this to be US$1 per computer-network-interaction-hour, billed monthly. Again, more on this later.

And there's so much more. Tomorrow, anyone attending Web 2.0 Expo will be able to get hands on with Bungee Connect. We've got a booth with PCs (Windows, Macs and Linux) with the browser open (IE, Firefox and Safari) where you run through some tutorials and judge for yourself if you think we're all smoking crack (see pics below - no crack, just the booths). We'll also be updating the site with screencasts and plenty more details and Martin will be presenting and demo'ing with Brad on Wednesday morning. And by then I'm sure David might have something more to say too...

To underline a couple of points here: we're not live yet. We go into Beta in May and are looking for web developers who ideally already have experience in progamming against the APIs of the companies I mentioned earlier. So sign up if that sounds like you...

Q406 computer books sales

alexbarnett — Wed, 17 Jan 2007 18:16:00 GMT

Tim O'Reilly has posted the second part of the Q406 computer books sales report, comparing Q4 2006 with Q4 2005. This is for top selling computer-related books sales in the US, not just O'Reilly titles. Always interesting as an indicator of trends.

Here the highlights for me...The following compares Q4 2006 to Q4 2005:

Overall 'computer' book sales up 4%
Databases category up 6% (I can't see the detailed breakdown in the enterprise db space other than SQL Server is up and Oracle is down - hope Tim provides an update on this later)
Programming languages: Java down 14%, '.NET languages' up 34%, Ruby up 53%, Python up 37%, Perl down 23%,
Web design and development category up 7%
Ajax up 55%, Rails up 43%
Business apps category down 8%: 'crm general' up 256%, collaboration down 23%, Sharepoint down 24% (Sharepoint Server 2007 coming)
Windows XP down 33% (Vista effect I suspect...)

OAuth Podcast, with Chris Messina (aka FactoryJoe), Larry Halff (of Ma.gnolia) and Eran Hammer-Lahav, November 3 2007

"OAuth is a big idea, but is it a "solution looking for a problem to solve"? I don't think so. The problem for end users today is real, i.e. authorizing one service to access your data by another service for use by the first service, securely and with control. For developers wanting to develop apps and services that create value through the use of customer data stored on other services, there is no standardized means set of protocols to lean on. Instead, developers need to waste time learning a new way for their app to be authorized to do so for each service provider, having to jump through the various specific means and idiosyncrasies of each service."

Jeff Barr on Amazon Web Services (Part 1), October 18 2007

"Developer evangelist for Amazon Web Services, Jeff Barr tells Alex and Ted about how he became a native Amazonian, his recent visit to “The Business of API’s Conference,” and a bunch of stuff on Amazon Web Services, including: Mechanical Turk, EC2, and S3.
