Big Data Europe Meetup in Vienna, 15th of December

On the 15th of December, a Big Data Meetup will take place in Vienna, with leading personals from Fraunhofer, Rapidminer, Teradata et al.

About the Meetup:

The growing digitization and networking process within our society has a large influence on all aspects of everyday life. Large amounts of data are being produced permanently, and when these are analyzed and interlinked they have the potential to create new knowledge and intelligent solutions for economy and society. Big Data can make important contributions to the technical progress in our societal key sectors and help shape business. What is needed are innovative technologies, strategies and competencies for the beneficial use of Big Data to address societal needs.

Climate, Energy, Food, Health, Transport, Security, and Social Sciences – are the most important societal challenges tackled by the European Union within the new research and innovation framework program “Horizon 2020”. In every one of these fields, the processing, analysis and integration of large amounts of data plays a growing role – such as the analysis of medical data, the decentralized supply with renewable energies or the optimization of traffic flow in large cities.

Big Data Europe (BDE, will undertake the foundational work for enabling European companies to build innovative multilingual products and services based on semantically interoperable, large-scale, multi-lingual data assets and knowledge, available under a variety of licenses and business models

On 14-15 December 2015 the whole BDE team is meeting in Vienna for a project plenary and thereby around 35 experts in the topic will be participating in the Big Data Europe MeetUp on 15 December 2015 at the Impact Hub Vienna to discuss challenges and requirements and proven solutions for big data management together with the audience.

RACEing to agile Big Data Analytics

I am happy to announce the development we did over the last month within Teradata. We developed a light-weight process model for Big Data Analytic projects, which is called “RACE”. The model is agile and resembles the know-how of more than 25 consultants that worked in over 50 Big Data Analytic projects in the recent month. Teradata also developed CRISP-DM, the industry leading process for data mining. Now we invented a new process for agile projects that addresses the new challenges of Big Data Analytics.

Where does the ROI comes from?

This was one of the key questions we addressed when developing RACE. The economics of Big Data Discovery Analytics are different to traditional Integrated Data Warehousing economics. ROI comes from discovering insights in highly iterative projects run over very short time periods (4 to 8 weeks usually) Each meaningful insight or successful use case that can be actioned generates ROI. The total ROI is a sum of all the successful use cases. Competitive Advantage is therefore driven by the capability to produce both a high volume of insights as well as creative insights that generate a high ROI.

What is the purpose of RACE?

RACE is built to deliver a high volume of use cases, focusing on speed and efficiency of production. It fuses data science, business knowledge & creativity to produce high ROI insights

How does the process look like?

The process itself is divided into several short phases:

  • Roadmap.That’s an optional first step (but heavily recommended) to built a roadmap on where the customer wants to go in terms of Big Data.
  • Align. Use-cases are detailed and data is confirmed.
  • Create. Data is loaded, prepared and analyzed. Models are developed
  • Evaluate. Recommendations for the business are given

In the next couple of weeks we will publish much more on RACE, so stay tuned!

What is necessary to achieve interoperability in the Cloud?

What is necessary to achieve interoperability in the Cloud?

As described in the previous sections, 3 major interoperability approaches arise. First, there is the standardisation approach, next there is the middleware approach and last but not least there is the API approach. This is also supported by [Hof09] and [Gov10]. In addition to that, [Gov10] suggests building abstraction layers in order to achieve interoperability and transportability.

There are two main aspects where interoperability is necessary. One level is the management level. This deals with handling the virtual machine(s), applying load balancing, setting DNS settings, auto scaling features and other tasks that come with IaaS solutions. However, this level is mainly necessary in IaaS solutions as PaaS solutions already take care of most of it. The other level is the services level. The services level is basically everything that comes with application services such as messaging, data storage and databases.

interop approaches

These requirements are described in several relevant papers such as [End10], [Mel09], [Jha09].

Parameswaran et al. describes similar challenges for Cloud interoperability. The authors see two different approaches, the first via a unified cloud interface (UCI) and the second via Enterprise Cloud Orchestration [Par09].

A unified cloud interface is basically an API that is written “around” other cloud APIs that is vendor specific. It requires some re-writing of and integration. This is similar to the approach selected by Apache jClouds and Apache libcloud.

The Enterprise Cloud Orchestration is a layer where different cloud providers register their services. The platform then provides these services for users like in a discovery. This is very similar to UDDI. The downside of this is that the orchestration layer still needs to integrate all different services (and built wrappers around them). However, it is transparent to the end-user.

Discussion of existing standards and frameworks for Cloud Interoperability

As discussed in the previous sections, there are several standards and interoperability frameworks available. Most of them are infrastructure related. The standards and frameworks can generally be clustered into 3 groups.

The first group is the “Standards” group, which consists of OCCI an the DMTF standards. The second group is the “Middleware” group. This group contains mOSAIC, the PaaS Semantic Interoperability Framework and Frascati. The third group is the “Library” group. This group is a concrete implementation that provides a common API for several cloud platforms. The two projects in here are Apache jClouds and Apache libcloud.

OCCI provides great capabilities for infrastructure solutions, but there is nothing done for individual services. The same applies to the standards proposed by the distributed management task force.

As with the libraries and frameworks, a similar picture is drawn. Apache jClouds and Apache libcloud provide some interoperability features for infrastructure services. As for platform services, only the blob storage is available. When developers build their applications, they still run into interoperability challenges.

mOSAIC offers a large number of languages and services, however, it is necessary to build a layer on top of an existing platform. This is not a lightweight solution, as a developer has to maintain both – the developed application and the middleware solution installed on top of the provider. The developer eliminates the vendor lock-in, but runs into operational management of the mOSAIC platform. This eliminates a problem on the one side but might create a new one on the other side.

The same problem exists with the PaaS Semantic Interoperability Framework. A user has to install a software on top of the cloud platforms, which then has to be maintained by the user. The goal of platform as a service is to relieve the user from any operational management like in IaaS platforms. Frascati is also a middleware that needs to be maintained.

All of the libraries or frameworks described work for IaaS services. None of them support the PaaS paradigm and services related to it. Apache libcloud and Apache jClouds offer some very fundamental support for the storage service. However, other services such as messaging and key/value storage are not supported.

PaaS Semantic Interoperability Framework (PSIF)

PaaS Semantic Interoperability Framework (PSIF)

Loutas et al. defines semantic interoperability as “the ability of heterogeneous Cloud PaaS systems and their offerings to overcome the semantic incompatibilities and communicate” [Lou11]. The target of this framework is to give developers the ability to move their application(s) and data seamlessly from one provider to another. Loutas et al. propose a three-dimensional model addressing semantic interoperability for public cloud solutions [Lou11].

Fundamental PaaS Entities

The fundamental PaaS entities consist of several models: the PaaS System, the PaaS Offering, an IaaS-Offering, Software Components and an Application [Lou11].

Levels of Semantic Conflicts

Loutas et al. [Lou11] assumes that there are 3 major semantic conflicts that can be raised for PaaS offerings. The first one is an interoperability problem between the metadata definitions. This occurs when different data models describe one PaaS offering. The second problem is when the same data gets interpreted differently and the third is when different pieces of data have similar meaning. Therefore, [Lou11] uses a two-level approach for solving semantic conflicts. The first level is the Information Model that refers to differences with data and data structures/models. The other level is the data level that refers to differences in the data because of various representations.

Types of Semantics

Three different types of semantics are defined [Lou11]. The first type is the functional semantic. This is basically a representation of everything that a PaaS solution can offer. The second type, the non-functional semantic, is about elements such as pricing or Quality of Service. The third semantic is the execution semantic, which is describing runtime semantics.
