Earlier today, Daryl Plummer introduced a new word into the cloud lexicon: the Cloudstream. Anyone who knows Daryl would agree he is one of the great taxonomists of modern computing. As Group VP and a Gartner Fellow, Darryl is in a unique position to spot trends early. But he’s also sharp enough to recognize when an emerging trend needs classification to bring it to a wider audience. Such is the case with Cloudstream.
In Daryl’s own words:
A Cloudstream is a packaged integration template that provides a description of everything necessary to govern, secure, and manage the interaction between two services at the API level.
In other words, Cloudstream encapsulates all of the details necessary to integrate services—wherever these reside, in the enterprise or the cloud—and manage these subject to the needs of the business. This means a Cloudstream describes not just the mechanics of integrating data and applications (which is a muddy slog no matter how good your integration tools are), but also aspects of security, governance, SLA, visibility, etc. These are the less obvious, but nonetheless critical components of a real integration exercise. Cloudstream is an articulation of all this detail in a way that abstracts its complexity, but at the same time keeps it available for fine-tuning when it is necessary.
Cloudstream captures integration configuration for cloud brokers, an architectural model for which Daryl is very much a proponent. Cloud broker technology exists to add value to cloud services, and a Cloudstream neatly packages up the configuration details into something that people can appreciate outside of the narrow hallways of IT. If I interpret Daryl correctly, Cloudstreams may help IT integrate, but it is the business who is the real audience for a Cloudstream.
This implies that Cloudstream is more that simple configuration management. Really, Cloudstream is logical step in the continuing evolution of IT that began with cloud computing. Cloud is successful precisely because it is not about technology; it is about a better model for delivery of services. We technologists may spend our days arguing about the characteristics and merits of different cloud platforms, but at the end of the day cloud will win because it comes with an economic argument that resonates throughout the C-Suite with the power of a Mozart violin concerto played on a Stradivarius.
The problem Daryl identifies is that so many companies—and he names Layer 7 specifically in his list—lead with technology to solve what is fundamentally a business problem. Tech is a game of detail—and I’ve made a career out being good at the detail. But when faced with seemingly endless lists of features, most customers have a hard time distinguishing between this vendor and that. This one has Kerberos according the WS-Security Kerberos Token Profile—but that one has an extra cipher suite for SSL. Comparing feature lists alone, it’s natural to loose sight of the fact that the real problem to be solved was simple integration with Salesforce.com. Daryl intends Cloudstream to up level the integration discussion, but not at the cost of loosing the configuration details that the techies may ultimately need.
I like Daryl’s thinking, and I think he may be on to something with his Cloudstream idea. Here at Layer 7 we’ve been thinking about ways to better package and market integration profiles using our CloudSpan appliances. Appliances, of course, are the ideal platform for cloud broker technology. Daryl’s Cloudstream model might be the right approach to bundle all of the details underlying service integration into an easily deployable package for a Layer 7 CloudSpan appliance. Consider this:
The Problem: I need single sign-on to Salesforce.com.
The Old Solution: Layer 7 offers a Security Token Service (STS) as an on-premise, 1U rackmount or virtual appliance. It supports OASIS SAML browser POST profile for SSO to SaaS applications such as Salesforce.com, Google docs, etc. This product, called CloudConnect, supports initial authentication using username/password, Kerberos tickets, SAML tokens, x509.v3 certificates, or proprietary SSO tokens. It features an on-board identity provider, integration into any LDAP, as well as vendor-specific connectors into Microsoft ActiveDirectory, IBM Tivoli Access Manager, Oracle Access Manager, OpenSSO, Novell Access Manager, RSA ClearTrust, CA Netegrity…. (and so on for at least another page of excruciating detail)
The Cloudstream Solution: Layer 7 offers a CloudStream integrating the enterprise with Salesforce.com.

The buzz continues for cloud, data analytics and the Internet of Things (IoT) and their collective impact across all industries. But a new conversation is emerging - how do companies use industry disruption and technology enablers to lead in markets undergoing change, uncertainty and ambiguity? Organizations of all sizes need to evolve and transform, often under massive pressure, as industry lines blur and merge and traditional business models are assaulted and turned upside down. In this new da...

The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data...

Today’s connected world is moving from devices towards things, what this means is that by using increasingly low cost sensors embedded in devices we can create many new use cases. These span across use cases in cities, vehicles, home, offices, factories, retail environments, worksites, health, logistics, and health. These use cases rely on ubiquitous connectivity and generate massive amounts of data at scale. These technologies enable new business opportunities, ways to optimize and automate, al...

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.

As the world moves towards more DevOps and microservices, application deployment to the cloud ought to become a lot simpler. The microservices architecture, which is the basis of many new age distributed systems such as OpenStack, NetFlix and so on, is at the heart of Cloud Foundry - a complete developer-oriented Platform as a Service (PaaS) that is IaaS agnostic and supports vCloud, OpenStack and AWS. In his session at 17th Cloud Expo, Raghavan "Rags" Srinivas, an Architect/Developer Evangeli...

DevOps has often been described in terms of CAMS: Culture, Automation, Measuring, Sharing. While we’ve seen a lot of focus on the “A” and even on the “M”, there are very few examples of why the “C" is equally important in the DevOps equation. In her session at @DevOps Summit, Lori MacVittie, of F5 Networks, will explore HTTP/1 and HTTP/2 along with Microservices to illustrate why a collaborative culture between Dev, Ops, and the Network is critical to ensuring success.

There are many considerations when moving applications from on-premise to cloud. It is critical to understand the benefits and also challenges of this migration. A successful migration will result in lower Total Cost of Ownership, yet offer the same or higher level of robustness. Migration to cloud shifts computing resources from your data center, which can yield significant advantages provided that the cloud vendor an offer enterprise-grade quality for your application.

As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ability. Many are unable to effectively engage and inspire, creating forward momentum in the direction of desired change. Renowned for its approach to leadership and emphasis on their people, organizations increasingly look to our military for insight into these challenges.

The IoT market is on track to hit $7.1 trillion in 2020. The reality is that only a handful of companies are ready for this massive demand. There are a lot of barriers, paint points, traps, and hidden roadblocks. How can we deal with these issues and challenges? The paradigm has changed. Old-style ad-hoc trial-and-error ways will certainly lead you to the dead end. What is mandatory is an overarching and adaptive approach to effectively handle the rapid changes and exponential growth.
