Enterprise Architects Appreciate “Lean”

Standing out from our conversations with dozens of Enterprise Architects at last week’s Forrester Enterprise Architecture Summit 2011 in The cloud descends on San Francisco for the Forrester EA Summit 2011 [Jonathan Marsh from the Golden Gate Bridge 2/16/2011]San Francisco was the interest in and appreciation of “lean” approaches to integration challenges.  From a lot of nodding in the room after Paul’s assertion that a lean solution was a key factor in eBay’s choice to use the WSO2 ESB in their ultra-scale deployments, to expo floor conversations with Enterprise Architects who are tired of suffering under bloated old industrial middleware and perking up at the idea that this is not inevitable, I came away with the impression that we may be on the cusp of a “lean” wave.

Let me be clear, while the WSO2 Carbon platform is lean it’s not skinny.  Through a sophisticated componentization model based on OSGi, there are hundreds of features to choose from, comprising a complete middleware platform from data to screen.  You just don’t typically need them all at once.

What are some of the factors that are driving the lean movement?  I think they include:

  • Simplified installation, configuration, and provisioning.
  • Low resource use, specifically modest disk and memory footprints.
  • High performance as a result of a simple straight-line approach to the problem at hand.
  • Immense productivity and reliability gains which occur when a tool addresses the problem at hand directly, not through multiple layers of generalization and abstraction.

This lean mentality kind of reminds me of my Microsoft days during which Windows Server Data Center Edition was introduced.  DC is essentially a version of Windows Server stripped down to its leanest, most performant and secure core.  It surprised me at the time that they charged significantly more for less actual code.  But it does demonstrate the value proposition of “lean,” and why it may now be a trending topic in the field of Enterprise Architecture.

Why Governance isn’t just for SOA – but Identity too!

People often think of security in terms of barriers. But anyone who looks after a barrier knows that its an ongoing process. And managing processes is what we call governance. A few years ago, I would talk to people who had put in place a firewall. They were convinced they were now “secure”. But then I’d ask what process they had to monitor the firewall and its logs. Unfortunately too often a look of “do I have to do that?” crept onto their faces. Without governance, a firewall is no good: if you don’t know someone is making a concerted effort to attack you, they will eventually get through.

It is not just firewalls that require governance. Increasingly I see examples of security issues that also are linked to governance. I think Wikileaks is a good example: whoever did it had too much access (not policy based but simply yes/no) and there was no “alert” that perhaps an unusual access pattern was in operation. Similarly I recently heard of a situation where an employee kept their online work log in for six months after they left the company.

Too many keys, copyright 2011 Jonathan MarshThere are two prime causes for this:

  • Firstly, there are too many identities. Each of us knows we have tens if not hundreds of identities on different systems. And there is no overall control of those identities.
  • Secondly, there are too many places that permissions are checked, or not checked. On the whole we rely on each application to implement permissions and there is a huge lack of consistency between these systems.

Its possible to fix some of these problems with manual governance processes. But even better is to automate them: the least human effort giving the most security.

We believe that there are two key technologies that can help:

1. Federated Identity Tokens

For example – SAML2 – the Security Assertion Markup Language v2 is a standard for XML-based identity tokens. These tokens give us two big benefits: single-sign on and federated identity. SAML2 can help unify as many systems as possible around a single identity. You can configure Salesforce or Google Apps to accept SAML2 tokens from a system driven by your internal LDAP. When an employee leaves, all you need to do is to remove them from your LDAP system and they are automatically shut out of all SAML2 based systems. This is an example of federating the identity from your internal model into Salesforce or Google. Amazingly, unlike most security systems that make life harder, SAML2 actually helps your users, because it gives them single-sign on onto many different websites.

How does SAML2 do this? The key benefit of SAML2 is that the user authenticates to a single “identity server”. Then this server creates a token which is trusted for a limited time by the target. The token can contain a variety of information (“claims”). These claims can be used as part of any authorization process. For example, a claim could assert that the user is logging in from a secure network.

2. Policy-based authorization and entitlement

For example: XACML – the XML Access Control Markup Language – does for authorization what SAML2 does for authentication. It allows a single policy based model for who can access which resources. XACML is very powerful too. It can work in conjunction with SAML2 to create very rich security models. For example, you can allow different access to users who are logged into a secure computer on a secure network as opposed to users coming via their laptop from Starbucks.

XACML does this by being able to capture complex “entitlement” logic into the Policy. The Policy is an XML file that can be stored in a smart registry. For example a policy might state that user Paul may access a salary update process between 9AM and 5PM GMT if Paul is in Role Manager.

 

The title of this blog is that governance is not just for SOA. SOA Governance has been — in our view — an area where the architecture community has learnt a lot of useful lessons. Let’s try to apply the SOA Governance lessons to Identity and Security Governance.

In the SOA world a common pattern for governance is the combination of a Registry and an ESB. The secret to this is:

  • Using policy and metadata instead of code, and managing the metadata in a Registry.
  • Moving towards a canonical model and transforming legacy systems into the canonical model.
  • Putting in place central logs and monitoring.

It turns out we can learn exactly the same lessons for Identity:

  • Using XACML to have a consistent model and way of defining authorization and entitlement using policy instead of hard-coding it into apps and storing these policies in a Registry.
  • Audit Log, Copyright 2011 Paul FremantleUsing SAML2 as a canonical model for Identity and bridging that into legacy systems as much as possible.
  • Using common auditing across your Policy Enforcement Points (PEPs) to ensure a single central audit log.

With this kind of model the governance becomes much more simple and automated. Removing a user’s login permission can remove login from everything. Authorization can be based on policies, which can be managed using processes. Even remote systems like Salesforce will still be included in the audit, because when a user signs in via SAML2, the SAML2 token server will create an audit event.

OpenID and OAuth are alternatives that perform similar and complementary functions to SAML2 and XACML, and are supported by a number of websites and web-based systems.

Good governance is tricky, and an ongoing process. The best way to get good governance is to automate it around simple straightforward approaches. The trio of metadata, canonicalization and log/audit is a great start and putting in place a solution around that architecture is an effective way to improve your Identity Governance.

Recognizing the Stars

No, this post is not about the Golden Globe Awards. This post is about another special awards ceremony that also took place last weekend — the annual WSO2 Awards Night!

Every year here at WSO2 we pay tribute to the top outstanding contributors. The entire team  really contains a whole bunch of stars but some do shine especially bright. Without imagetheir passion, commitment, and attitude to shine the extra mile, we would not have come this far in redefining middleware and providing support services matched by no other.

Like the Globes we’ve got a bunch of categories too: Outstanding Contributor of the Year, Customer Delight, and Outstanding Team of the Year.

And this years’ winners were … drum roll please …

Outstanding Contributor Award: Samisa, Azeez, Supun, Buddhika, Charitha, Saminda, Milinda, Evanthika, Krishantha, Chathuri, Padmika, Janath, Devaka, Shankar, Sumedha, Udeshika

Customer Delight Award: Prabath, Senaka, Hiranya, Asanka Abeysinghe, Chamith, Kasun, Nirosh

And the Outstanding Team of the Year Award goes to … the QA Team, for putting out 46 releases, about 150 patches, and 16 cloud releases, while remaining (mostly) sane.  Incredible work!

This year for the first time, we also gave out long service awards for those who’ve been in the Company for five years, which is practically since its inception. There were nine long-timers in total, including yours truly! :)

Its been a great team to work with and each year only gets better than the one before. So here’s to another outstanding year — 2011 here we come!

How much should you care?

A couple of weeks ago, I recorded a podcast with Paul O’Connor and Dana Gardner. Paul O is someone I’ve worked with on and off for about four years now, first as he helped customers Podcast iconnavigate SOA and now as he leads their thinking in Cloud. It was immense fun recording the podcast with Paul, but, if anything, we only scratched the surface of Paul’s thinking. He is one of the real visionaries of how Cloud is going to affect large businesses IT and completely rewire it.

Paul O believes that the end-game of true cloud computing is the ability for a business to completely focus on the business and have the IT from infrastructure to development completely available as a Service. Paul calls this the Grand Unified Theory of Cloud: consuming IT entirely as a service.

I personally don’t agree: I think that there needs to be a sliding line that divides IT from the pieces I have to care about to the pieces I don’t. Twenty years ago I cared about processor instruction sets and assembly code. Today I don’t. Today, I don’t care what actual hardware my Amazon images run under — there is a rough measure and the details don’t bother me. On the other hand, if I was doing algorithmic trading, I care even about the clock frequency I can rack the machine up to. I don’t believe that we will ever get to a line where the business doesn’t care about any of the details — that simply opens up an opportunity for another business to find competitive advantage by finding something to care about. But I do agree with Paul: at the moment we are forced to care about too many aspects.

Here at WSO2 we are trying to create a platform where you can stop caring about 99% of the middleware issues and we can provide a platform that just takes care of that for you. The real Grand Unified Theory of Cloud for me is being able to choose exactly what to care and focus on in your IT, and have the other parts just work — as a service.

Defining a Generic API

With a premium placed on loose coupling, a typical SOA deployment displays a high degree of heterogeneity. Different service platforms run in scattered datacenters on a variety of server hardware, operating systems, and development platforms. The services expose different communication and security standards. Individual SOA implementation and maintenance teams will become acclimated to the level of heterogeneity with exposure to the environment, but when an external or internal consumer tries to access the SOA, they will come face to face with this complexity.

image

A common way to simplify and normalize interactions with a heterogeneous environment is to provide a unified API for service consumers — a unified, generic service layer.

One of our commercial bank customers with multiple service platforms began a project of defining a unified services layer, generalizing the the multiple service platforms active in the bank. At first they approached the problem in the traditional way: writing wrapper/proxy services in front of each of the existing services.  As part of an engagement with WSO2 they changed to a “Generic API” solution pattern which dramatically simplified the project by hiding the internal complexity of each service behind a user friendly API, a common URL for service access, and unified security policies.

The “Generic API” pattern installs a common API for the existing service infrastructure, converts traditional applications to services exposed over a normalized set of communication and security protocols, and provides a foundation supporting the easy addition of future service platforms.

image

When implemented with WSO2 products, the Generic API pattern leverages the WSO2 Enterprise Service Bus (ESB) and WSO2 Governance Registry. The WSO2 ESB connects with the back-end service layers and legacy applications, and exposes them through a new service layer.  This is easily accomplished with the proxy service capability of the WSO2 ESB.  Supporting a wide variety of of the transports and message formats, the WSO2 ESB provides a central hub for protocol switching and security mediation between the heterogeneous systems.

With sophisticated transformation capabilities, the WSO2 ESB extends the Generic API pattern to the problem of unifying data models, by converting or mapping messages representing different data models into a common and easily consumed model.

Storing and publishing common metadata such as service descriptions and policies describing the generic API also aids new developers interacting with the system.  In the deployment above, the WSO2 Governance Registry provides a common repository for storing and sharing all the necessary SOA artifacts.

The Generic API pattern provides the foundation for other other solution patterns as well.  In future posts we’ll discuss solution architectures for a Public Services Gateway and an Internal Services Gateway pattern.

Get Ready for Summer – SOA Style

As you gear up for summer, sign up for our ever-popular SOA Summer School program starting in June.

No idea what SOA Summer School is? Well it’s a two-month program that offers weekly online sessions on various topics relating to enterprise SOA. We started WSO2 SOA Summer School in 2009 to help IT architects and developers beat the recession and imageupdate their knowledge and insights into the latest SOA technologies and best practices. We got such great feedback, we ran it again last year and are expanding it with brand new content this year.

While we’ve covered basic technology in the previous sessions, this year we focus on practical solutions to real world challenges faced by enterprises today. We’ll showcase WSO2-based solutions, from security to governance to enterprise integration and cloud. We’ve also changed the format a little bit as well — the sessions are now more intensive and only two hours long.

Here’s the list of sessions that you can sign up for by going to http://wso2.org/training:

  • Security policy enforcement for the enterprise
  • Identity Management in the Cloud
  • End-to-end governance in the enterprise
  • Enterprise integration with SAP and WSO2 ESB
  • Enterprise Integration with the FIX Protocol
  • Mobile-izing enterprises with the WSO2 Mobile Services Gateway
  • Master Data Management in your SOA
  • Platform-as-a-Service: The WSO2 way
  • Wrap-up: The Best of Summer School 2011

Think Again.

Tomorrow at the Forrester Enterprise Architecture Forum 2011 (WSO2 is a Gold Sponsor and talking about Ultra-scale deployments) we are launching a new campaign – the “Think Again” campaign.  The theme of our booth and materials is:

Think there’s nothing new in middleware?  Think Again.

This campaign idea originated during a conversation we had recently during an investor analysis of WSO2 technology and business.  The comment was “WSO2 is the only new thing in the middleware space.”  We received similar excitement from analysts over our platform at the Gartner AADI conference last year, a recognition that our deliverables today match the Platform-as-a-Service vision predicted at the conference for five years out.

The foundations of this claim are solid:

  • Our lean and modular approach is unique and provides clear customer value.
  • Our cloud-native platform gives you a full range of deployment options, from on-premise server installations, virtualized environments on- or off-premise, or fully multi-tenant, elastic cloud deployments on public or private infrastructure.
  • And our open source business model and world-class support services raise the bar on software vendor-customer relationships.

A small taste of the campaign is available at http://wso2.com/thinkagain.

So, think we’re just a low-cost alternative to IBM, Oracle, Tibco, and the rest?  Think again.

WSO2 in Banking and Finance

We have had a number of recent engagements using the WSO2 Carbon platform in the banking and finance industries, and I thought it would be useful to talk about some of them and highlight the ways in which we are working with financial institutions.

Our platform has currently been used by a number of financial institutions, in both retail and wholesale banking. For example, one financial institution uses our ESB in Asset imageManagement, several others use us for FIX support in various areas (e.g. Bond Trading, FX Trading) and meanwhile we have several retail banks that are using a variety of components from Carbon for full SOA enablement including Governance, ESB, distributed Identity Management and Data Services – for example two institutions in the mortgage and lending space.

The deployments include several in the US (both East and West Coast), Switzerland, Germany, Mexico and the Ukraine.

One of the factors here is the strong uptake of SOA in the Banking and Finance sector and the unique position WSO2 has as a leading Open Source SOA Platform provider. Another key factor is the fact we are pretty much the only ESB that comes with out-of-the-box support for FIX (with no additional cost either). But I also like to think that one of the success factors is simply success: we are very good at helping our customers succeed in their endeavors.

If you want further information, we published a nice case study this week.  Or come along to to http://wso2.com/contact/ and one of our Account Managers will help kick off the discussion.
