Introduction

Businesses looking to establish themselves online have numerous options. They can not only choose the providers, but the service they wish to receive. Cloud computing has become an extremely popular hosting method due to flexibility in price, features, and support/management. Within the concept of cloud computing, you are typically presented with three distinct categories of services offered: 

What is Telepresence?

Initially developed by Datawire, Telepresence is a new open-source tool supported by the CNCF (Cloud Native Computing Foundation). It allows developers to run local software while connected to a remote Kubernetes cluster. The application uses a two-way network proxy to simulate TCP connections, environmental variables, and other volumes of services as local processes. This link allows for remote work to be accomplished while seemingly local to the cluster via the proxied connection. 

What is ClickHouse?

ClickHouse is an open-source column-oriented DBMS (or database management system) primarily used for OLAP (or the Online Analytical Processing of queries). It is capable of blazing fast generation of real-time analytical data and reporting utilizing SQL queries. It is fault tolerant, scalable, highly reliable and contains a feature rich tool set.

What is ArangoDB?

ArangoDB is a high availability and scalable multi-model NoSQL database that natively works with graphs and documents and includes a full-text search. It is a free, open-source software developed and maintained by ArangoDB GmbH. The system supports three different data models with one database core and includes a unified query language called AQL (ArangoDB Query Language). This query language is declarative and allows the combination of different data access patterns in a single query. The software can be implemented on multiple systems, including Windows, macOS, Linux, Kubernetes, Docker, and on our Managed Cloud. It has a strong community support base on GitHub, StackOverflow, Google Groups, and Slack.

What is Chef?

Chef is an open-source configuration management DevOps tool used for configuration and management of multiple systems in infrastructure. Using Chef, we can use so-called recipes and cookbooks to automate and speed up managing multiple systems in our environment. By using Chef, we can adjust every system in our environment to our desired state, which we defined using the code in recipes. In the process, code is continuously tested and deployed using Chef.

What is Thunderbird?

Thunderbird is one of the most widely used open-source email clients in the world. Mozilla originally developed the software in 2004, but the project waned in 2014/15, and Mozilla stated that they would only deliver security and maintenance updates in the future. Until recently, the community maintained the software when a Mozilla Foundation subsidiary, MZLA Technologies Corporation, took over. Today, the improvements in security and stability are very much appreciated, and since version 78, Thunderbird has built-in OpenPGP encryption technology enabled by default. Earlier versions used the available PGP technology, but it needed to be installed as a supplemental plugin. 

Introduction

In this tutorial, we will examine what Neo4j is, what it is used for, and how it is implemented. We will also install and configure the installation on an Ubuntu 20.04 server. Neo4j is a graphical database used to create data relationships. Other examples of graphical databases include:

What is Jenkins?

Jenkins is an open-source software written in Java and Scala. This software allows users the ability to automate almost any task and, it saves significant time that can be better utilized addressing other issues. When automating tasks with Jenkins, users can optimize their workflow by quickly automating the jobs that servers cannot do themselves. In this tutorial, we will learn how to install Jenkins on CentOS 8. We will also explore what its purpose is and share several benefits that Jenkins offers. We will then configure it to run on our CentOS 8 server.
