On Ed Yourdon Presents: Mashups!

[Cross-posted from JackBe blog]

I am big fan of Ed Yourdon. So, I was delighted to see his presentation on Mashups (here). Discussion on this topic by eminent and experienced gurus like him are heart warming and encouraging to me, since we at JackBe, have been working in the area of Mashups to create a new kind of lite-middleware. I and my colleagues have often written about our work (for instance here and here).

What was not so encouraging to me personally was the fact that Presto, our enterprise mashup platform from JackBe, did not figure in his presentation. Which got me thinking, no surprise really, there must be a whole lot of people that might not know or heard about us since we are such a small company compared to the likes of Google, Yahoo, IBM and Microsoft, which were featured mentions in his presentation.

So, to those, I would also like to take this opportunity to introduce our company, JackBe and our product Presto, which is a pure play enterprise mashup server platform built from the ground up for enterprise mashing! At the core of this is our Enterprise Mashup Markup Language (EMML), which we describe as a domain specific language for mashups. No other product or technology offers such a DSL for mashing, which has been greatly appreciated by our users and customers. Do check it out yourself and let me know what you think.

We also offer Presto to developers in a special developer edition to the community. The Mashup Developer Community (MDC) members can download and use Presto for free here (requires registration).

In Ed Yourdon’s presentation, he mentions Yahoo! Pipes, MS Popfly, etc. Some have described Presto as Yahoo! Pipes on steroids for the enterprise, since Presto’s visual mashup composer called Wires allows you to create mashups that consume any kind of service / API including WSDL, REST, RSS, Atom, Databases, Excel spreadsheets and so forth. Pipes only deals with public RSS services as far as I know.

Presto also generates Mashlets, which puts a face (UI) in front of each mashup. Mashlets become the embeddable objects that can virally spread within and outside the enterprise (assuming the enteprise security policies allow them to share outside). All of this is done in a secure manner, which is why we are an enterprise mashup solution.

To better understand Presto at a high level, I had previously described the 3 artifacts of mashup process here. I hope this provides you some insight into our technology, and hopefully, you will get to try it when you get a chance. While doing so, if you do need any help, don’t be shy to ask on MDC, the whole community is there to help!

Mash On!

Mashups: New and Agile way to Integrate

I came across this interesting post: How Mashups Could Eliminate Integration Projects by Loraine Lawson. In a related post, she refers to John Crupi’s article Enterprise Mashups Part I: Bringing SOA to the People which I would recommend to readers who want to understand JackBe’s take on defining mashups. Anyway, Loraine’s post led me to Ron Schmelzer’s ZapFlash.

Here are some excerpts of Ron’s article that caught my eye, with my take on it:

A year or two ago, assuming that a mashup was a web browser-based, static, user interface composition of web-based functionality would be a reasonable presumption. But in the enterprise context, none of those assumptions necessarily hold – we might want non-Web access to mashed applications, we might want to change them regularly, and we might want to mash up information that exists below the user interface abstraction. For sure, Web mashups might embody the ideals of the original mashup concept, but we now have the desire to mash up a wide variety of IT resources from application to infrastructure to data that might be exposed with a wide range of interfaces – or without. And, it’s the desire to mash up information freed from the application that diversifies the mashup term to include the concept of the data mashup.

Introducing the Mashup Tier

My take: This hits the point right on what we at JackBe have been saying all along about mashups. While some mashups are done purely in the UI/Browser, in the enterprise, such mashups need to be supported by a new tier, the mashup tier, which sits between the presentation and business tier. So enterprise mashups will have some mashing done in the client, but most of the mashing happens in server side where security, governance, policies can be applied before any mashing can happen in the client.

Another excerpt:

There are many scenarios for composing data, but some are better suited for static, tightly-coupled, IT-driven, non-Service Oriented form. In fact, 80% of the value that businesses derive from data come from the 20% of fixed, highly optimized data integration approaches implemented over decades. In this realm, traditional data integration approaches retain high value. However, it’s the other 80% of data integration requirements, most of which come from the need to meet short-term, often ad hoc, integration requests that cause 80% of the problems. Anyone who has lived long enough in the enterprise IT space knows that business-driven requests for reporting, forecasting, analysis, or other interpretations of data can present significant complications and cost to the IT organization. The reason for this is that the IT organization is set up to meet the recurring needs of the business and not “situational” needs for information.

Long Tail of Enterprise Software Demand

My take: This highlights another issue which we have been talking about at JackBe about the long tail & enterprise applications need which was so nicely discussed here by Dion Hinchcliffe.

Bottom line: Something new and interesting is happening in the enterprise architecture space. A new flexible and agile tier is being introduced in the architecture to meet the increasing demand on IT and  add value to existing architecture, applications, services and data. Question is, are you embracing this inevitable change? If not, it’s still not too late.

SV Code Camp Session Report: Enterprise Mashups

Session: Enterprise Mashups / Presenter: Kishore Subramanian, JackBe

[ Disclaimer: I work for JackBe ] There are about 30 attendees. Kishore is going over the concepts behind our mashup approach like mashables, mashups, and shareables.

Kishore demonstrating SalesForce mashups and walking through the internals including EMML code. Talking about how you can merge data from SalesForce with data from internal proprietary data source and merge/combine to produce a mashup (virtual) service. Showing how to invoke it as a REST interface, which makes it easier to use a complex/mashup service. Now showing how to make a Mashlet using MashletMaker and sharing the mashlet. Now he is demo’ing Wires to show how to visually mashup by drag, drop and connect.

SV Code Camp Session Report: Working with Sharepoint Data

Session: Working with Sharepoint Data @ SV Code Camp / Presenter: Joseph Ackerman, Senior Consultant with Allin Corp. MS Partner

Things I heard (caution: I am not a Sharepoint user or developer):

• Sharepoint development is not fun. 80% audience (~30 prople) raise hands as sharepoint users.
• Had never heard of CAML until now…CAML=Collaborative Application Markup Language
• Sharepoint woefully under-documented for developers, getting better but right now it sucks.

Mashables > Mashups > Shareables

[Cross posted from Mashup Developer Community]

How exactly does the mashup process work? What does Presto really do? These are a couple of common newbie questions. I have had different explanations for this, but of late, I have narrowed down on the following elevator pitch (trust me, this textual explanation looks long, but I can explain really fast in person) that I have used successfully with other developers recently. So I thought I will share this with the community in case it helps others to understand the process and artifacts around enterprise mashups.

I found it easier to explain the whole mashup workflow using three terms: Mashables, Mashups and Shareables (OK, I confess, these may not be in the English Dictionary yet ).

As a mashup developer or user, we need to start somewhere. To me that starting point is what I call Mashables. These are things that one can use, invoke to get data and send data. Things like services such as WSDL based web services, REST based web services,  RSS or Atom services, proprietary XML/RPC services, or even the conventional RDBMS tables, view and stored procedures. I would also include other items such as spreadsheets, XML documents and unstructured information on internal and external websites. These are the raw material for mashups. These need to be made Mashable! And this is exactly what happens when you ‘publish’ one of these things to Presto. It becomes a Mashable artifact that can be normalized, secured and managed.

And then comes the second thing called Mashups. I don’t want to go into a philosophical discussion about what a mashup is or isn’t. However, I think mashup is a user-driven, user-focused thing that encapsulates the kind of data processing and manipulation actions a user would normally do to turn any data into real information. Such actions include joining, merging, sorting, filtering, constructing, transforming, clipping, and so forth. And in Presto, a mashup is represented by an small file written using EMML (EMML is Enterprise Mashup Markup Language). EMML is an XML-based dynamic declarative domain specific mashup language. Again, a Mashup becomes this artifact which can be secured and managed just like the Mashables.

The third and final thing is the Shareables. Once you have Mashables, and Mashups, you want to be able to share them with co-workers, partners, friends, whoever. Shareables can be exposed as a service interface so others can use it as a REST or RSS or Atom or WSDL service. Another popular type of Shareable is what we call Mashlets, which are enterprise widgets that offer a rich interface to the Mashups. Mashlets are not full blown applicaitons, but can be small micro-applications that encapsulate a very specific functionality. Mashlets can be shared by publishing them on Wiki pages, blogs, websites, portal servers. You can even email a mashlet or call it directly from a smart phone like iPhone. Other types of shareables include mashups and services shared as REST urls, RSS feeds, data feeds, spreadsheets, email and so on.

There you have it. Now I can just describe Presto simply as a platform to securely create, publish, consume and collaborate with Mashables, Mashups, and Shareables !

Let me know what you think.

Presto Mashup Platform – Developer Edition

A few days ago, we released the complete Presto Enterprise Mashup Platform for all mashup developers to use free: Click here for more details and to download it. Enjoy!

Presto on GlassFish

Works With
JackBe Presto is bundled with and runs on the popular Apache Tomcat server out of the box when you download and install it. But as a pure Java application, Presto is designed to run on any standard compliant J2EE application server that has JSP/Servlet support.

I wanted to deploy Presto on Sun’s open source J2EE application server, GlassFish, since a few of our friends at Sun were interested. If you are new to GlassFish, it is the name for the open source project for building a Java EE 5 application server sponsored by Sun & Oracle (more details here).

The process of deployment was very easy. If you have downloaded and installed Presto, it is easy to locate the Presto war files that represent different Presto capabilities and deploy them using the GlassFish administration console or the command line asadmin utillity that comes with the GlassFish installation. With just a click of a few buttons, the following Presto components were deployed on GlassFish:

• Presto Edge Enterprise Mashup Server with Service Explorer and Administration Console applications for managing Edge
• Dash, our user driven dynamic desktop application
• Sample applications to show mashup examples and data binding examples

That and an evaluation license key you get when you download our software is all you need to run Presto on GlassFish. Kudos to our development team for a great job in maintaining standard compliance and pure Java in our code. Pretty cool!

Mashing the Enterprise Service Cloud

[Cross-posted from http://blogs.jackbe.com]

In my last blog entry, I defined what I mean by a mashup. In this entry, I want to expand upon how I think mashups differ in the enterprise compared to some of the consumer mashups out there.

I mentioned in my earlier post that mashups based on maps are ubiquitous and something that the users can immediately grasp. But, once you step inside an enterprise, things can be a lot different for mashups. Enterprises are not greatly interested in map-based mashups, neither are they interested in RSS or ATOM services which I think are still not fully leveraged inside an enterprise. Over the past few years, enterprises have invested heavily in SOA and because of that, they are just about getting done with service orienting their enterprise with Web Services (primarily using WSDL). And there are many applications in the enterprise that are still very database oriented. It has become relatively easy for an IT developer to expose services as WSDL based web service. And almost every middleware product out there in the enterprise is capable of exposing services via WSDL or makes it really easy to do so. Hence if you start looking around in an enterprise, what you will find is what I call the Service Cloud.

So what you have in an enterprise is a cloud of services where some are WSDL based, some are REST based, some or XML/HTTP, some are database objects, and so forth. Now, the real challenge is how to mashup these disparate kinds of services, with different service contracts and data formats. Any respectable enterprise platform that offers to mashup services in the enterprise must negotiate these disparate contracts these services expose (e.g. while a WSDL based web service defines a service contract in a WSDL document, a REST based web service has no such contact definition). And not only that, it must be done so that that we can make it easy to access for developers and users alike, and to be able to do that securely and with high-performance and scalability. Some enterprises might regulate the service consumption of even public web services that most of us can freely access on the net (think of the ubiquitous RSS feeds for example). Enterprises might allow consumption of these services, but would like to do so with governance underneath to manage, monitor and secure such activity within the enterprise. This is why we built our enterprise mashup platform at JackBe from the ground up, to address the unique challenges of mashing in the enterprise so that we allow our users to do the following:

• Create and customize mashups that consume all kinds of services: RSS, ATOM, WSDL, REST, DB, SDO, Java Objects, etc.
• Securely govern the mashups: policies for who can mashup, what can they mashup
• Share the mashups to collaborate in the enterprise

My colleague John Crupi wrote about enterprise mashups becoming the new front-tier in the enterprise. I would like comment a bit on what he said in his post. While SOA efforts have been IT driven and IT oriented, even with involvement by the business units, the outcome has been primarily IT and developer focussed. It has neglected an important stakeholder in the enterprise, and that is the User. Therefore, I view the new enterprise mashup layer as a new service layer in the enterprise application architecture that finally begins to leverage SOA from the end user perspective and to make the services layer more user-friendly (and developer-friendly) to build, deploy, share the next-generation enterprise web 2.0 mashup applications.

Defining Mashups

[Cross-posted from http://blogs.jackbe.com]

Over the last year, the term mashup has become extremely popular not only in the consumer software space, but also in enterprise software. It has been a little more than a year since I joined JackBe as VP of Engineering responsible for executing our vision. Over this time, I and our team at JackBe has been busy creating our enterprise mashup platform, which is a unique innovative offering in enterprise software today, by combining the benefits of RIA technologies such as Ajax/RIA, Web Services, Service Oriented Architecture and Mashups.

At the internal technology briefing last week, I and my team presented and demonstrated the features of Presto, JackBe’s enterprise mashup family of products, to 25 developers and consultants. One of the important areas of discussion was around what we mean by a mashup and how the term ‘mashup’ has evolved over the last year to mean almost anything. For example, the following is the definition of the term mashup on Wikipedia:

A mashup is a website or application that combines content from more than one source into an integrated experience.

The problem with this definition from my perspective is that it allows you to practically label anything as a mashup, including a portal application, composite application, and what have you that brings disparate content onto a single web page.

I don’t think I want to disagree with this or any other definition of a mashup floating around in the industry. However, I feel that all the existing definitions and explanations are lacking something so important about the real intent of these mashups. This was also apparent at the discussion a few weeks ago at the IBM Mashup Ecosystem Summit. So, now I feel compelled to offer you what we at JackBe mean by a mashup:

A mashup is a shareable software block created by a user, encapsulating ad-hoc user driven processing of disparate data sources, delivered with a user focused view.

Allow me to elaborate further using the following characteristics:

1. Mashups are made up of user driven micro-orchestrations. In other words, when I access some data or service, I am performing small operations on the way data is computed and rendered in a very informal and iterative manner. For example, consider how one uses a spreadsheet which is a great example of a canvas where mashups happen in the enterprise when a user pulls in data from different sources, combines, sorts, computes, filters and visualizes by iteratively processing it until he gets the desired results. If you really think about it, what the user is doing is really orchestrating getting data from different sources and processing using one or more operations to yield an integrated view of the data.
2. Mashups are user focussed, i.e. they are primarily created by the user for the user. They are not the product of some developer or IT guy writing a lot of code. However, current examples of mashups that we see are primarily developer oriented, it is just the beginning. The real value of mashups comes when we enable and empower our end users to perform these mashups the way they want to do it without having to call and rely on IT needs.
3. Mashups are ad-hoc creations and are very situational based on users immediate short term needs. They are designed by the user to meet a specific need. These mashups have a very short life span varying from hours to days. This is the reason that the users cannot wait and demand IT to create and deliver these mashups.
4. Mashups can be visual and non-visual. The most common kind of mashup that is out there is probably something that overlays some information on some kind of a map. However, there is more to mashups than just displaying pins on a map. I can mashup disparate data to create an integrated data view. I can mashup processes to create a new process. I can mashup domain models of different application domains to create a new application domain model.
5. And finally, mashups can be performed on the client side and on the server side. However, I think the best value of a mashup is when we combine both client side and server side mashup functions since we can defer heavy lifting to the server and build intelligent clients that can enhance, complement and focus on user experience.

Before I conclude, I would like to emphasize a few points.

1. Whether we do visual or non-visual, client-side or server-side, mashups must be user driven and user focussed.
2. Just because mashups are user driven and user focussed does not mean that we no longer need IT. IT is still a critical part of the whole mashup infrastructure in an enterprise. However, instead of the users going to IT for every little thing they need which can be transient, situational and ad-hoc, they should be able to accomplish what they need without having to rely on traditional IT and experienced programmers to build what they need. For example, imagine what would happen if Microsoft Excel users needed IT help to write a macro or to create a chart from a table of data they put together. Mashups in the enterprise must address these kind of needs of enterprise users accessing disparate data and services to create and share new information in the Enterprise Web 2.0 world.

In my next blog entry, I will discuss more about our work in creating our comprehensive enterprise mashup platform that encompasses the above characteristics. It finally feels great to be able to talk about what we have been obsessively building over the past year!

What do you think? I am really interested to hear other opinions and thoughts around this.
