Big Data in the Telecommunication Sector
We supported a large German telecommunications provider in the planning, development and operation of a performance critical application. The Apache Flink and Hadoop Data Platform based application is used for invoice generation as well as to categorize and process mobile network events. For simple use, the application offers a lightweight single page frontend using Vue.js and TypeScript.
Application Server Upgrade
We performed an upgrade of the application server at a large telecommunications company, replacing the old WebLogic 12.1.2 with the current 12.2.1 version. The most important effect was a substantial reduction in response times on all external interfaces. Behind the scenes we adapted the system to make further upgrades significantly easier.
Innovator in Application Operations Teams
We supported an application operations team in the financial sector by rejuvenating or decommissioning old core applications. We used automated configuration management (Puppet), updated OS and application frameworks, standardized and simplified scripts and configuration for a maintainable, environment-indepedent layout.
As well as reworking application monitoring (Check_MK), we created structured operational manuals using Confluence templates and trained internal employees.
We evaluated new technologies (such as Elastic Stack 5), implemented proof-of-concept applications and supported developers with the introduction of the frameworks into existing applications.
Rejuvenation of a Legacy Application
After five years of stabilizing, consolidating and developing a monolithic Java backend application for a large telecommunications company, we opened a new chapter in the system architecture during the development of an important new feature. The feature was conceived and implemented from the start as a microservice, communicating with the existing application via REST. We introduced Hibernate as ORM: a further improvement on the existing, custom-developed data access layer. For the build system we replaced ant with gradle. The effect is a significant modernization of the legacy system landscape, in terms of both architecture and technology.
We upgraded the basic platform for an eCommerce client. This platform forms the heart of the application, offering solutions for customer and production managements as well as the possibility to model the entire commercial process.
As well as migrating the database to be able to meet new requirements, we performed the necessary adaptations to the interfaces of the Java application running on the platform platform. This enabled a modern software configuration with more up-to-date versions for Tomcat, Spring and Java.
Poker "Brains versus AI"
From 11-31 January in Pittsburgh, four of the world's best players played in a no-limit Texas Hold'em Poker tournament against an AI, "Libratus", developed at the Carnegie Mellon University. Libratus won the tournament, which TNG sponsored, by a large margin, marking a milestone in the history of artificial intelligence.
Articles in Technology Blog Heise Developer Online
TNG employees contributed two articles to the important German technology blog Heise Developer Online: an Article on the Big Data technologies Apache Spark and Apache Flink in the summer and, together with one of our clients, an Article on REST with HATEOAS in December. The latter reached 14th place amongst the most read articles of the year 2016.
Development and Implementation of a Customer Matrix
We supported a telecommunications provider in the development and implementation of a customer matrix for the Customer Relationship Management (CRM) systems. Customer value and the probablility of contract termination for each end customer are recalculated every day in the Data Warehouse and transmitted to the CRM systems. Agents in the Service Centre and Point of Sales receive valuable information about the end customer and have the best possible support for providing personal customer care. The customer matrix also allows the CRM team to define standard strategies and to specify individual customer offers.
Munich Team wins the Hyperloop Pod Competition
TNG was the first sponsor of the TU Munich's Hyperloop team. The first ideas for participation in the competition run by SpaceX and Elon Musk go back to autumn 2015. The efforts of the student team, involving up to 30 students, were rewarded with victory in the competition and the prizes for "fastest pod" and "best performance in flight". Neither the strong competition from Delft and MIT nor the heavy rain and customs' confiscation of the batteries could prevent the win. We congratulate the team and look forward to the talk at the next Big Techday!
Replacement of a Legacy-Web-Application
We supported a client with an online platform in the development of a website, using ES6, React and Fluxible with high test automation. The backend employs a microservice architecture with Scala, Kafka and MongoDB. After several months of development, the legacy version of the top entry page was replaced by a newly developed page with responsive design.
