BI is Dead. Long Live BI. The Future of Business Intelligence in the Cloud

I’ll be delivering a keynote presentation in Sydney Australia on Oct 18 at the Mastering Business Intelligence with SAP conference. I’ll also be doing a roadshow around the country with our local partner First Point Global, who really understand the business of IAM. The Australian market is very forward-looking these days, and I’ve been impressed with the vision behind the projects we’ve been involved in. If you’re in Australia, come by the conference or send me an email if you would like to meet.

Here’s the abstract in full:

BI is Dead. Long Live BI. The Future of Business Intelligence in the Cloud

Will cloud computing really change IT? Despite all of the attention that cloud computing commands, this deceptively simple question has been largely overlooked. The promise of shifting capex dollars to lower opex is certainly compelling and the overnight success of some of the large Software-as-a-Service (SaaS) vendors, such as is undeniably impressive. But once the hype dies down, what will be the real impact of cloud computing to mission-critical applications such as BI?

Cloud will transform BI, much as it is currently transforming CRM. Cloud isn’t only about a cheaper new delivery model; when done right, cloud also radically changes how applications are composed and where data can reside. These changes are driven both by necessity-acknowledging the realities of latency, privacy and compliance – but also by opportunity and the rapidly evolving best practices that show us how to build applications better and deliver these faster. BI must change to be successful in the cloud and cloud is an irresistible forcing function that will make this change inevitable. If your career is centered around BI, you need to be ready for this revolution.


Virtualization’s Second Act

I was quite disappointed with the coverage and analysis of VMware’s new vCloud Director (VCD) product, which the company introduced at its annual VMworld conference earlier this month in San Francisco. I think people focused too much on the superficial message of vCD being yet another new cloud platform, but missed the more important insight into what makes this product different from the virtualization we all know so well.

I wrote up my own take on the real change vCD represents in terms of organizational behavior, work flows, and approaches to managing mass virtualization. It was published this week on the VMware blog, so I must have been at least partially right. Go have a look and tell me what you think.

Upcoming Webinar: How To Implement Enterprise-scale API Management: The secret to making your business into a platform.

Jeffery Hammond, Principal Analyst with Forrester Research and I will be jointly delivering a webinar Tuesday, Sept 28th at 9am Pacific time. The topic we are discussing is API management and security. We’ll look at why APIs are important, and discuss the best practices for effectively leveraging these in your business.

Figure 1: The role of gateways in API management.

This promises to be a very good presentation, and I’d urge you to attend. We’re doing something a little different this time and delivering a much more interactive discussion than some of my past webinars. Since Jeffery and I are both traveling over the next few weeks, we’ve run through our rehearsals early. The material is top notch; Jeffery absolutely understands the issues organizations face as they attempt to expose core business applications using APIs. We are very much on the same page, and I have a strong feeling that this is going to be a very good show. I’m looking forward to it, and I hope you can join us.

The Increasing Importance of Cloud Governance

David Linthicum published a recent article in eBizQ noting the Rise of Cloud Governance. As CTO of Blue Mountain Labs, Dave is in a good position to see industry trends take shape. Lately he’s been noticing a growing interest in cloud management and governance tools. In his own words:

This is a huge hole that cloud computing has had.  Indeed, without strong governance and management strategy, and enabling technology, the path to cloud computing won’t be possible.

It’s nice to see that he explicitly names Layer 7 Technologies as one of the companies that is offering solutions today for Cloud Governance.

It turns out that cloud governance, while a logical evolution of SOA governance, has a number of unique characteristics all its own. One of these is the re-distribution of roles and responsibilities around provisioning, security, and operations. Self-service is a defining attribute of cloud computing. Cloud governance solutions need to embrace this and provide value not just for administrators, but for the users who take on a much more active role in the full life cycle of their applications.

Effective cloud governance promotes agility, not bureaucracy. And by extension, good cloud governance solutions should acknowledge the new roles and solve the new problems cloud users face.

How to Secure vCloud Director and the vCloud API

This year’s VMworld conference saw the announcement of VMware’s new vCloud Director product, a culmination of the vision for the cloud computing the company articulated last year and a significant step forward in providing a true enterprise-grade cloud. This is virtualization 2.0—a major rethink about how IT should deliver infrastructure services. VMware believes that the secure hybrid cloud is the future of enterprise IT, and given their success of late it is hard to argue against them.

vCloud Director (vCD) is interesting because it avoids the classic virtualization metaphors rooted in the physical world—hosts, SANs, and networks—and instead promotes a resource-centric view contained with the virtual datacenter (VDC). vCD pools resources into logical groupings that carry an associated cost. This ability to monetize is important not just in public clouds, but for private clouds that implement a charge back to enterprise business units.

Multi-tenancy is a basic assumption in the vCD universe, and the product leverages the new vShield suite to enforce isolation. Management of vCD is through the vCloud API, a technology VMware introduced a year ago, but which has now matured to version 1.0.

The product vision and implementation are impressive; however, a number of security professionals I spoke with expressed disappointment in the rudimentary security and management model for the vCloud API. vCloud is a RESTful API. It makes use of SSL, basic credentials and cookie-based session tokens as a basic security model. While this is adequate for some applications, many organizations demand a more sophisticated approach to governance, buttressed with customized audit for compliance purposes. This is where Layer 7 can help.

Layer 7’s CloudSpan virtual gateways are the ideal solution for protecting and managing the vCloud API, vSphere, and vCloud Director. CloudSpan provides an intuitive, drag-and-drop interface for securing vCloud services and providing the visibility the modern enterprise demands. Do you need to protect the interface with 2-factor authentication? A few simple key clicks and you add this capability instantly—to a single API, or across a group of similar services. The CloudSpan policy language gives administrators the power to customize the access control and management of vCloud to incorporate:

  • Authentication against virtually any security token (SAML, Kerberos, X.509 certificates, OAuth, etc).
  • Cloud single sign-on (SSO).
  • Fine grained authorization to individual APIs.
  • Fully customizable audit.
  • Virtualization and masking of APIs.
  • Versioning of REST and SOAP APIs beyond vCloud basic versioning.
  • Augmentation and extension of existing vCloud functions.
  • Transformation of any GET, POST, DELETE, and PUT content.
  • Orchestration to create new APIs
  • Validation of XML structures such as OVF containers.
  • Threat detection, including threats embedded in XML OVF files.
  • Automatic fail-over between hosts.
  • Mapping between SOAP and REST
  • JSON Schema validation
  • Management of federated relationships.
  • Live dashboard monitoring of API usage.
  • etc

CloudSpan is the basis of real cloud governance. In contrast to other solutions that run as third party services or attempt to broker security from you own local data center, CloudSpan runs as an integral part of the vCloud Director environment. CloudSpan runs as a VMware virtual image that is easily incorporated into any VMware virtual infrastructure. At Layer 7,we fundamentally believe that the security, monitoring and visibility solution for cloud APIs must reside inside the cloud they are protecting—not off at some other location where the transactions they proxy are subject to attach as they traverse the open Internet. Local integration of the security solution as an integral part of the cloud infrastructure is the only way to properly secure cloud APIs with sophisticated access control and to offer protection against denial-of-service (DoS) attacks.

Public vs. Private Clouds

Christian Perry has an article in Processor Magazine that I contributed some quotes to. The article is about the ongoing debate about the merits of public and private clouds in the enterprise.

One of the assertions that VMWare made at last week’s VMWorld conference is that secure hybrid clouds are the future for enterprise IT. This is a sentiment I agree with. But I also see the private part of the hybrid cloud as an excellent stepping stone to public clouds. Most future enterprise cloud apps will reside in the hybrid cloud; however, there will always be some applications, such as bursty web apps, that can benefit tremendously from the basic economics of public clouds.
