What ist DaaS?

DaaSWe live in the age of Big Data but Big Data is not showing up to the party alone. Fast data and open data are also coming along for the ride. This is why we need an “as-a-service” approach to data sharing. In a recent article for Big Data Republic, I explored the concept of data-as-a-service (DaaS) and some of the operational challenges associated with providing access to Big Data.

The fact that these challenges are not just theoretical considerations was driven home to me by one of our customers, who told me that he simply didn’t have enough IT cycles to keep writing and rewriting all those queries and APIs his customers were asking for.

Similarly another recent article on Big Data Republic, refered to three powerful drivers for machine learning identified by Tibco CTO Matt Quinn – drivers that I believe are equally relevant to data APIs:

  • “A surge of data being liberated from places where it was previously hidden (aka big data’s volume challenge)
  • A need for automation that manages the complexity of Big Data in an environment where humans have no time to intervene (aka Big Data’s velocity challenge)
  • An absolute requirement to create adaptable, less fragile systems that can manage the combination of structured and unstructured data without having a human write complex code and rules with each change (aka Big Data’s variety challenge)”

The efficiency gains and resulting agility and potential for innovation created by data-centric APIs are enormous – not just in respect to open data but also the ability to turn data into an active asset and monetize it. For an inspiring story, head over to Andorra via FastCompany.

Meanwhile, an interesting take on the way IoT is increasingly driving data democratization – and creating new governance challenges in the process – comes from  Christopher J. Rezendes and W. David Stephenson in an article at the HBR blog network. Naturally, the best place to implement and enforce data governance is in the API that provides access to the data.

Secure API design and management is not rocket science. Our API Academy is offering best practices and practical advice on everything from API design to API security to API lifecyle management (and yes, that includes versioning).

Focusing on the Byte-Sized Tree: The IoT Conundrum

Written by

Data Lens for IoTYesterday, we introduced the concept of a Data Lens for aggregating and sharing data. Today, I want to talk about why this concept matters to organizations concerned with the Internet of Things (IoT).

Simply put: “things” generate petabytes of data. Putting sensors on everything, as both Cisco and GE propose, creates a data nightmare. Hadoop has made analyzing big volumes of data much easier but what happens when you want to share a small sliver of that information with a customer or partner? After all, the purpose of “Big Data” collection is not altruism – it’s about monetization. In many situations, this will only be possible if data can be shared easily.

A Data Lens gives IoT data owners – such as manufactures or telco carriers – an easy and secure way to share a focused and billable data set with their customers and partners. Anything outside of the scope of a Data Lens cannot be accessed, whereas anything inside the lens is  “in focus”. The data in focus can be raw or aggregated. There can be any number of Data Lenses on a data set. They can be used internally or shared securely with external partners and customers. Data access through individual Data Lenses can be governed by service level agreements and – through metering – monetized.

For manufacturers and network operators looking at ways to share focused data slices from their Big Data, a Data Lens solves a big problem. By leveraging the Layer 7 API Gateway’s unique ability to focus on small data sets inside larger ones and to present these data sets as secure APIs, customized to specific customers or partners, it’s possible for IoT operators to drive new revenue from their Big Data.

Getting Perspective on Your Big Data

Data LensAs we see it here at Layer 7, there are two big problems with Big Data:

1. There’s just so much of it that it’s easy to lose sight of the byte-sized trees in the petabyte-sized forest

2. It’s locked away in every recess of the enterprise – from applications to relational databases, to non-relational databases, to in-memory caches, public clouds, Hadoop clusters etc.

Data growth and diversity have made data access harder. But data access is the foundation of mobile app development, anything to do with the Internet of Things (IoT) and all kinds of Big Data analytics. Given this need for data in the face of access complexity, it didn’t come as a total surprise to see some of the most innovative Layer 7 customers start using our API Gateway technology as a novel data access, aggregation and presentation solution. As our resident IoT expert Holger Reinhardt pointed out to me: they are using our products to build highly-customized “lenses” across their distributed data backends. To me, this characterization is perfect because what these customers are looking for is perspective on their data. A lens gives perspective with focus.

Now, a Layer 7 API Gateway is more than just a data integration solution. Our technology has several unique features that make it ideal for collecting, composing and presenting data. First, we can talk to all kinds of data sources natively. That wasn’t easy to achieve and it’s something we developed over many years. Second, we can represent the source data as a RESTful API. Even better, we can dynamically generate a virtual API view for a specific user, app, partner etc. The API then becomes the entry point for accessing the aggregated data. Third, we can add fine-grained access and protection policies that ensure only authorized consumers get visibility to specific slices of data, while also protecting the data sources from attack and misuse. When combined, these capabilities give organizations a way to focus on just the information that is relevant to a particular mobile, IoT or Big Data analytics project and then share selectively with an app, cloud service, developer or partner.

A data lens is born!
