Phase 1: Continuous Development Plan

Tools used: Slack, JIRA, Blueprint, IBM

1. DevOps tools – Slack:

Technologies for workplace communication and collaboration are as numerous and diverse as one can imagine. When deciding which tools are best suited to specific business requirements, several factors are taken into account, including integration and automation capabilities, security, user experience, and whether to develop, buy, or rent.

slack

Slack is one of the most popular communication and collaboration tools, and for good reason. First and foremost, Slack provides free, standard, and enterprise-paid versions to meet the needs of a diverse range of clients. It provides features such as group and direct messaging, file sharing, and integration with other tools and services commonly used in DevOps, such as code repository platforms, issue trackers, and automation tools. This helps DevOps teams to streamline their communication and collaboration, and increase efficiency and productivity.

Slack is a stand-alone application that boasts:

  1.  Powerful capabilities with well-designed search modifiers to simplify document tracking, management, and file sharing.
  2. A user-friendly project management architecture integrates with tools such as Twitter, Google Hangouts, Trello, and others.
  3. Powerful collaboration and communication capabilities via shared channels, direct chat, voice, and video conferencing.
  4. Workflow builder, notification, and note-taking features have been added.

Slack is a simple application with an intuitive user interface and a plethora of pre-built integration points, making it an excellent supplement to over 900 other business tools. It can be accessed via a web browser, synchronized with your desktop, and used on mobile devices such as tablets and smartphones. Slack also provides a large amount of storage space and a diverse set of integrations (paid versions).

2. DevOps tools – Blueprint:

A blueprint encapsulates the skills that an organization wishes to possess at the end of the program. It aids in determining which systems and technologies are required for the organization’s success. It clarifies the required skills and abilities, as well as the type of culture the organization wishes to foster.

blueprint

While vision within a program is important for keeping work relevant and aligned, an organization also requires a more detailed model that describes what the desired future state is and how this will work.

The blueprint’s goal is to achieve this. In practice, the blueprint provides the vision’s “behind the scenes” details. It accomplishes this by describing how to get from point A (where we are now) to point B. (where we want to be).

In contrast to business as usual and the annual budget that drives short-term and technology solutions, the blueprint directs organizations toward strategic long-term investments.

3. DevOps tools – JIRA:

Jira Software is part of a suite of products designed to assist teams of all sizes in managing their workload. Jira was originally intended to be a bug and issue tracker. Jira, on the other hand, has evolved into a powerful work management tool for all use cases, ranging from requirements and test case management to agile software development.

Jira Software serves as the central hub for the coding, collaboration, and release stages for an increasing number of teams today. Jira integrates with a variety of add-ons for test management, allowing QA testing to be seamlessly integrated into the software development cycle.

The next phase after Continuous Development is Continuous Integration

5. DevOps tools – SVN:

Subversion is one of several version control systems that are available today. It is frequently abbreviated as SVN. Subversion is used to keep track of current and historical project versions. Subversion is a free and open-source version control system. It’s licensed under the Apache license. It is also known as a software version and revision control system. SVN is used to manage and track code and asset changes across projects.

 

SVN is a version control system that is centralized. It differs from distributed systems such as Git.

SVN Server Explained

The version history is stored in a central server with centralized version control. When a developer needs to make changes to a file, they download it from the central server to their computer. After making changes, the developer returns the modified files to the central server.

Gradle: Build Happiness | The Eclipse Foundation

Gradle is a build automation tool for Java-based projects. It is used in DevOps to automate the build, test, and deployment process of software applications. It combines the features of Ant and Maven, allowing developers to use a Groovy-based DSL (domain-specific language) to describe the build process and dependencies. Gradle also provides advanced features such as incremental builds, parallel builds, and build caching. This makes it a popular choice for modern DevOps practices, as it helps streamline the software development lifecycle and improve the efficiency of the development team.

gradleGradle can be used to manage dependencies as well. Managing dependencies is essential for keeping track of the libraries and frameworks on which an application is dependent. Gradle can assist in automatically resolving dependencies and can also download dependencies from public repositories such as Maven Central.

Gradle also includes a plugin system for extending it. Gradle has several plugins available, including plugins for popular build tools like Ant and Maven. These plugins can help to improve the efficiency of DevOps workflows even further.

10. DevOps Tools – Npm:

npm (software) - Wikipedia

Npm is two things: first, it is an online repository for publishing open-source Node.js projects, and second, it is a command-line utility for interacting with a said repository, which aids in package installation, version management, and dependency management. npm hosts a plethora of Node.js libraries and applications, with new ones being added daily. Once you’ve decided on a package to install, you can do so with a single command-line command.

Another important application of npm in DevOps tools is dependency management. If you have a node project with a package.json file, you can run npm install from the project root to install all of the dependencies listed in the package.json. This greatly simplifies the installation of a Node.js project from a git repository! 

A Node.js testing framework, for example, can be installed from git, and its single dependency, eyes, can be handled automatically.

13. DevOps tools – JUnit:

JUnit · GitHub

JUnit is an open-source Java testing framework. As the term “Unit Testing” implies, it is a method of testing a unit. A unit is the smallest piece of code that can be retrieved from the system. It could be a single line of code, a method, or a class. The smaller the piece of code, the better. When the tested units are small, the tests run faster, giving a better understanding of the code and its performance.

The testing framework is used by Java developers to write and run tests. We use it for unit testing of the source code, and JUnit works by testing a small part, then coding it, and repeating the process until the test passes.

When new code is added, all test cases must be re-run to ensure that nothing is broken. JUnit includes graphs that display the test’s progress. When the test runs smoothly, the graphs turn green; when the test fails, the graphs turn red. JUnit Testing enables developers to write more dependable, readable, and bug-free code.

The next phase after Continuous Testing is Scripting Language.

Phase 5: Scripting Language 

Tools used: Python, Powershell, Ruby, Go LINK

Scripting is an important part of DevOps. It is essential in DevOps for several reasons. 

For starters, it can help with task automation. This can save time while also ensuring that tasks are consistently completed. 

Secondly, it can be used to monitor and collect system data. This data can then be used to improve DevOps processes. Scripting can be used to manage and provision resources as well.

PowerShell or Python scripting languages are good places to start. These languages are simple to learn and have numerous DevOps applications.

14. DevOps tools – Powershell:

Microsoft PowerShell Training Classes and Certification

PowerShell is an open-source command-line interface (CLI) tool that enables developers, IT administrators, and DevOps professionals to automate tasks and configurations through the use of code.

PowerShell is a Microsoft. NET-based multipurpose attribute. PowerShell is a free and open-source shell that also functions as a scripting language.

PowerShell is used as a shell to control the computer using commands from the command-line interface of the operating system. Aside from the graphic user interface (GUI), which is used to convey commands from a user to an operating system, the command-line interface is another interface preference.

As a scripting language, PowerShell is primarily used to create automation that requires repetition with this shell functionality. This makes work easier and reduces the possibility of errors. All PowerShell use cases are covered by automation. Other scripting languages are used to create automation, but PowerShell is the most commonly used due to its unique format system. PowerShell is also a better option because it allows for customization through functions, classes, cmdlets, and modules.

Here’s a simple Windows PowerShell script:

Puppet uses a declarative language to describe the state of resources, and provides a framework for automating the process of provisioning, configuring, and maintaining systems and applications.

The following are some examples of daily tasks that Puppet can automate:

  1. Software installation
  2. Patching for security
  3. Modifying database settings

In Puppet, we write configuration files known as manifests that declare how we want our infrastructure to be configured using Puppet-specific code. For example, the Puppet code below ensures that Nginx is installed on our server (s).

package { ‘nginx’:

ensure => installed

}

When we define and manage infrastructure using configuration files, we are relying on a core DevOps principle: Infrastructure as Code.

To facilitate on-premise deployments, the server provides a run-time environment with cloud-based tools.

Cloud services, on the other hand, include tools for cloud software development, testing, and deployments such as Azure boards, Azure Pipeline, Azure reports, Azure test plans, and Azure artifacts.

The next phase after Cloud Computing  is Continuous Monitoring

Phase 10: Continuous Monitoring

Tools Used: Splunk, ELK Stack, Nagios, New Relic, Prometheus

31. DevOps tools – Nagios:

File:Nagios logo.png - Wikimedia CommonsNagios is a popular open-source software application for monitoring systems, networks, and infrastructure. In DevOps, Nagios can be used to monitor the health and performance of various components in the IT infrastructure, such as servers, applications, and services. It provides real-time notifications about issues and failures, which can help organizations identify and resolve problems quickly and minimize downtime. Nagios can also be integrated with other DevOps tools, such as Ansible and Puppet, to automate monitoring and configuration tasks.

Nagios Working - DevOps Tools - EdurekaNagios is used for the purpose of continuous monitoring of systems, applications, services, and business processes, etc in a DevOps culture. In case of a failure, Nagios can proactively alert the technical staff of the problem. This allows them to begin remediation processes before outages affect business processes, end-users, or customers. With Nagios, you don’t have to explain why an unseen infrastructure outage affects your organization’s bottom line.

32. DevOps tools – Prometheus: 

Monitoring Container and Node Metrics Using Prometheus, cAdvisor and Node-Exporter | by Arnav Tripathy | Medium

Prometheus is a critical component of DevOps. It has one of the largest open-source contributor communities and is the preferred database for time-series metrics data. It is also a component of Logz.io’s comprehensive observability package, which combines Prometheus, Jaeger, and ELK Stack into a single platform. It is popular for system and container monitoring.

Prometheus runs and monitors a wide range of systems. As a result, installation and configuration can differ from software to software, platform to platform, and environment to environment.

To know more about Prometheus you can have a look at the following video:

33. DevOps tools – New Relic:

New Relic Launches Industry's Only Full-Stack Change Tracking Solution | Business Wire

New Relic is an observability platform that assists developers in developing better software. You can import data from any digital source to fully comprehend your system and determine how to improve it. It offers various products such as APM (Application Performance Monitoring), Infrastructure Monitoring, Browser Monitoring, and more to help businesses improve their digital experience.

New relic devops tools
New Relic is an Application Performance Management (APM) tool that teams use to monitor applications. By monitoring application statistics that reflect overall application performance, the goal is to maximize productivity and minimize downtime.

Modern web application management necessitates paying attention to small details because these small details frequently combine to negatively impact the user experience. These parameters are revealed by the New Relic Application Monitoring Tool so that developers and site owners can take appropriate and timely corrective actions to improve performance.

33. DevOps tools – Sentry:

GitHub - getsentry/sentry-cli: A command line utility to work with Sentry.

Sentry is a DevOps app monitoring tool built on a stack of products including Snuba, Kafka, and Nginx. It includes proactive application monitoring to ensure that problems are identified and resolved before they disrupt the production environment.

Sentry is compatible with a wide range of programming languages, including Angular, Java, NodeJS, Serverless, Python, React, JavaScript, and others. Every environment, from Kubernetes to cloud instances or serverless computing, can be monitored.

Frontend deployments where the application is hosted in the cloud on a Kubernetes cluster or a cloud instance are the best deployment scenarios for Sentry (AWS, Google Cloud Platform, or Azure).

Sentry tracks how users interact with your applications. When an application is hosted in the cloud, monitoring data is only transmitted from the application server to the Sentry server. Clients in this scenario access the application via a web server or another SaaS delivery method.

With this, I have covered all of the DevOps phases and the tool used in each of these phases. So this was all from my side in this blog on DevOps Tools. I hope you now have a fair idea about the various DevOps tools.
