    By Marcelo Zucchelli, Project Manager

    Introduction

    What is RE?

    Requirements Engineering (RE) can be summarized as a set of activities that ensures a team is building the right product. In the field of Software Engineering, hence, it seeks the correct and suitable software deliverable.

    Now, what do correct and adequate mean? Correct is a deliverable that meets stakeholder expectations, i.e. that it realizes their vision of the product, while suitable relates to whether it is fit for purpose.

  • IoT Bridges as Microservices in DC/OS

    23 August 2016
    By Rafael Zubairov, Senior Architect

    IoT technologies have become a natural part of our life. And therefore the number of IoT protocols has grown exponentially. Device manufacturers (e.g. wearables, sensors, or temperature / light / environment controllers) use their own protocols for communication and cloud enablement. The cloud infrastructure can also use custom protocols of a higher level to receive device state updates and management information.

    Some platforms use low-level protocols (e.g. COAP) to interact with devices and MQTT to communicate with a central hub. Others use their own standards, built upon HTTP or WebSockets. Central hubs in turn can use a variety of protocols and methods for marshalling data. And imagine the mashup of all those protocols to connect to external services.

  • European Travel Sector — Unsettled Yet Undeterred

    27 May 2016
    By Charlotte Lamp Davies, VP of Travel and Hospitality, DataArt

    The third Phocuswright Europe Conference was held at the Convention Centre Dublin on the 10-12  of May  2016 and drew the continent’s top players to exchange views on the trends in technology for the European travel market. The theme was “Unsettled yet Undeterred”, reflecting the backdrop of Europe’s bumpy economic recovery and reduced spending on travel.

    The travel industry DNA is changing, with important shifts happening from one year’s Phocuswright to the next.

    Stephen Kaufer, CEO, Tripadvisor, emphasized the company’s shifting focus from a review resource to one that accommodates instant bookings. KAYAK and Google have also introduced direct bookings.

  • DC/OS as a platform for communication bridges

    10 May 2016
    By Rafael Zubairov, Senior Architect

    Today IoT is expanding it’s borders and creeping into our daily lives. Devices are placed everywhere, various size from tiny things to monstrous automatic machinery. The internal device architecture and design form the constraints on the device behavior. Device protocol, operational cycle, and time are often limited by batteries, the underlying hardware, and existing libraries. The variety of protocols and message types means a typical solution to unite them involves implementing bridge-adapters that are capable of transforming data into a common format.

    Bridges are often seen as a pipe accepting messages and passing them to the next collector or adapter-bridge. The central business logic resides in the middle. Central logic responsible for accepting and handling all the messages. The replies are sent back, routed through the channels back to the device and client. A typical solution will require several type of adapters to be deployed. With an increasing number of bridges, fault tolerance requirements should be kept. At this point, cluster maintenance and monitoring becomes important task.

    What has changed?

    For decades, POS workplaces have been built on standard PCs. Starting with DOS, then moving to other operating systems, COM-ports have been replaced by USB, but the situation hasn’t changed much: industrial PCs are put inside a specially designed computer casing.

  • On-demand Interactive Data Science with DC/OS

    19 April 2016
    By Yuri Gubin, Software Project Manager

    Traffic accidents in the UK, 1979-2004.

    Whether you are a journalist, a researcher or a data geek, in order to start working with large data sets, you have to complete laborious tasks of setting-up an infrastructure, configuring an environment, learning new unfamiliar tools and coding complicated apps – with DC/OS you can start crunching those numbers within minutes.

    Let’s start with a problem of analyzing a set of data and take a road safety data from Great Britain, 1979-2004. While the data set might seem small, some of the analysis might require distributed processing and we should have an environment that allows our processing jobs to scale horizontally. To achieve this, we’ll be running a DC/OS cluster on top of a cluster of virtual machines. We’ll be using AWS EC2 in this scenario, but the same solution can be ported to other public and private clouds.

  • Getting started with packages in DC/OS

    19 April 2016
    By Yuri Gubin, Software Project Manager

    Why would one create a package?

    Once you get familiar with DC/OS, the open source project that was created by Mesosphere you get access to packages certified by Mesosphere. There are several ways to deploy your service into DC/OS: (1) use dcos marathon command in CLI; (2) use Marathon REST API directly; (3) deploy your service as a package. Using package approach makes your solution consistent with the environment and gives other benefits.
