JupyterHub
JupyterHub, a multi-user Hub, spawns, manages, and proxies multiple instances of the single-user Jupyter notebook server. JupyterHub can be used to serve notebooks to a class of students, a corporate data science group, or a scientific research group.
Project Jupyter created JupyterHub to support many users. The Hub can offer notebook servers to a class of students, a corporate data science workgroup, a scientific research project, or a high performance computing group.
Eclipse Che
Eclipse Che is an open-source Java based developer workspace server and cloud integrated development environment (IDE) which provides a remote development platform for multi-user purpose. The workspace server comes with a RESTful webservice and provides high flexibility. It also contains a SDK which can be used to create plug-ins for languages, frameworks or tools
GitLab
GitLab is a web-based Git-repository manager providing wiki, issue-tracking and CI/CD pipeline features, using an open-source license. GitLab is used by several large tech companies including IBM, Sony, Jülich Research Center, NASA, Alibaba, Invincea, O’Reilly Media, Leibniz-Rechenzentrum (LRZ), CERN, European XFEL, GNOME Foundation, Boeing, and SpaceX.
Docker
Docker is a computer program that performs operating-system-level virtualization, also known as "containerization". It was first released in 2013 and is developed by Docker, Inc.
Docker is used to run software packages called "containers". Containers are isolated from each other and bundle their own tools, libraries and configuration files; they can communicate with each other through well-defined channels. All containers are run by a single operating system kernel and are thus more lightweight than virtual machines. Containers are created from "images" that specify their precise contents. Images are often created by combining and modifying standard images downloaded from public repositories.
Kubernetes

Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications.
It groups containers that make up an application into logical units for easy management and discovery. Kubernetes builds upon 15 years of experience of running production workloads at Google, combined with best-of-breed ideas and practices from the community.
PostgreSQL
PostgreSQL, often simply Postgres, is an object-relational database management system (ORDBMS) with an emphasis on extensibility and standards compliance. It can handle workloads ranging from small single-machine applications to large Internet-facing applications (or for data warehousing) with many concurrent users. It is widely available and is supplied in most distributions.
PostgreSQL is ACID-compliant and transactional. PostgreSQL has updatable views and materialized views, triggers, foreign keys; supports functions and stored procedures, and other expandability.
PostGIS
PostGIS is a spatial database extender for PostgreSQL object-relational database. It adds support for geographic objects allowing location queries to be run in SQL.
In addition to basic location awareness, PostGIS offers many features rarely found in other competing spatial databases such as Oracle Locator/Spatial and SQL Server.
MongoDB
MongoDB is a free and open-source cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with schemata.
Neo4j
Neo4j is a graph database management system developed by Neo4j, Inc. Described by its developers as an ACID-compliant transactional database with native graph storage and processing, Neo4j is the most popular graph database according to DB-Engines ranking, and the 22nd most popular database overall.
Neo4j is implemented in Java and accessible from software written in other languages using the Cypher Query Language through a transactional HTTP endpoint, or through the binary "bolt" protocol.
RShiny
Shiny Server is the simplest way for data scientists and R users to share their work with colleagues in a controlled environment. Shiny Server allows you to host the Shiny applications you create in a way that allows other users to access and interact with them, even on older web browsers like Internet Explorer 8 and 9. Each application can be configured to be available at its own URL and will be automatically started when it's accessed, and stopped when it's not in use. You can configure Shiny Server to be available only to those within your organization, or to users across the Internet.
Cloudera
Cloudera started as a hybrid open-source Apache Hadoop distribution, CDH (Cloudera Distribution Including Apache Hadoop), that targeted enterprise-class deployments of that technology. Cloudera states that more than 50% of its engineering output is donated upstream to the various Apache-licensed open source projects (Apache Spark, Apache Hive, Apache Avro, Apache HBase, and so on) that combine to form the Apache Hadoop platform. Cloudera is also a sponsor of the Apache Software Foundation.
Apache HTTP Server
The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows. The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards.
The Apache HTTP Server ("httpd") was launched in 1995 and it has been the most popular web server on the Internet since April 1996. It has celebrated its 20th birthday as a project in February 2015.
The Apache HTTP Server is a project of The Apache Software Foundation.
Originally based on the NCSA HTTPd server, development of Apache began in early 1995 after work on the NCSA code stalled. Apache played a key role in the initial growth of the World Wide Web, quickly overtaking NCSA HTTPd as the dominant HTTP server, and has remained most popular since April 1996. In 2009, it became the first web server software to serve more than 100 million websites. As of August 2018, it was estimated to serve 39% of all active websites and 35% of the top million websites.
CentOS 7
The CentOS Project is a community-driven free software effort focused on delivering a robust open source ecosystem. For users, CentOS offer a consistent manageable platform that suits a wide variety of deployments. For open source communities, we offer a solid, predictable base to build upon, along with extensive resources to build, test, release, and maintain their code.
