We might be unaware of this fact, but we use time series databases all the time. They will become even more relevant as the Internet of Things (IoT) and other revolutionary technologies continue to develop. In this article, we will review what a time series database is, what its purpose, and their impact on our daily lives.
In this tutorial, we are going to examine Jenkins and what its purpose is. We will begin by installing it on an Ubuntu 20.04 server and then start the software, enable the service, configure it, and finally, create a user with administrative privileges.
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.
DevOps is a set of various tools, practices, and ideals that combine software development (Dev) and IT Operations (Ops) into a single unifying force. It allows for better collaboration between developers, operations teams, system administrators, and system engineers. Their streamlined goal is to continually provide a high-value software product to the customer at high speed while monitoring and improving the overall process than using traditional software and infrastructure management.
Puppet is a cross-platform client-server based application used for configuration management. It handles the software and its configurations on multiple servers. There are two versions available. One is open-source, the other is a commercial version. It works on both Linux and Windows platforms. It uses a declarative approach to automate updates, installations, and other tasks. This feature allows the software to configure those systems using files called manifests. A manifest contains the instructions for a group or type of server(s) being controlled.
Cloud automation is a blanket term that is often used to denote specialized software, tools, and operations that help us reduce the manual effort when it comes to deploying and maintaining cloud-based IT infrastructure. Simply put, it is automating tasks programmatically.
Today, DevOps teams try to utilize automation as much as possible. This is to cut down on the sheer number of repeatable processes to limit man-hours worked, throttle development efforts, and to reduce the possibility of errors. This is also a business necessity to reduce overhead costs, increase the speed of the CI/CD process and increase customer satisfaction. There are multiple individual areas that need to be automated to have a fully autonomous infrastructure. Luckily, there are various tools we can take advantage of to help us automate our infrastructure and make sure we have well-developed DevOps processes. In this article we will go over the several of the best DevOps tools for our infrastructure systems.
Jenkins is an open source automation server software developed in Java. It allows developers to integrate CI/CD (Continuous Integration/Continuous Delivery) pipelines within their organization that ease and automate workflows. It has an extensive help community, supports over 1000 plugins, 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 are not able to do themselves. Jenkins has a wide array of features including building projects, executing unit tests for bug detection, analyzing static code, and deploying applications. For this article, we will learn how to install Jenkins on a Ubuntu 16.04 server using APT (Advanced Package Tool). When using APT, we can retrieve and install all of the needed dependencies as well.
