The two strong pillars for any organization’s software development life cycle is Development and Operations teams. In today’s fast paced IT industry, fast software delivery is the main goal for any Enterprise that reduces the cost and improves the ROI as well.
To attain this, DevOps culture is endorsed in various business verticals for their effective collaboration between cross-functional teams. Choosing the relevant DevOps tools for automating any infrastructure requires a sound knowledge of the existing DevOps tools, it’s capabilities and the required DevOps strategies to implement them.
The Elements of Infrastructure automation
1. Configuration Management
“Configuration management simplifies the most complex business tasks into manageable process & strengthens the organizations agility”
Configuration management emphasis on the Devops’s key metrics namely continuous testing & continuous delivery. Configurance-as-a-code (CaaC) is a series of scripting codes within any given resource which are deployed to implement the Devops cycle.
Now automating the tedious tasks is made easier by embracing the best configuration Devops practises where the system-wide changes are adapted swiftly even in any dynamic circumstances.
“Orchestration is more of interconnecting the components & processes among heterogeneous systems across various locations”
Just like a canoe race, where teamwork is the key to winning, Devops practices rely on effective coordination between cross-functional teams.
Orchestration streamlines and coordinates between the DevOps practises and the automation tools of any organization. These script-based infrastructure automation tools list, provides a set of commands that are deployed into the application.
Devops Engineers before deploying these commands should keep in mind a couple of things like few scenarios where these scripts will not work and the commands should be as comprehensive as possible.
3. Continuous Integration
“Fast Feedback is the key for implementing the continuous Integration process with integrated build & automated testing”
Through continuous integration, the developers write the code, perform unit test and commit the build to a server repository. However, the testing takes place simultaneously at both the feature level and the main branch level to identify any early bug defects with devops testing tools.
Also, within a day get frequent updates whenever a code is modified. This process helps in continuous DevOps process.
“Monitoring Your Application 24/7 in a secured and reliable environment”
Once built and deployed the appropriate code, monitoring them is the next stage. Monitoring the performance of the application comes under DevOps pipeline. There are several Application monitoring tools in DevOps namely Nagios, DataDog, Splunk and so on.
These processes are useful for streamling any mission-critical applications. It will monitor the network traffic, updates the maintenance schedules and fixes any issues automatically.
Devops Tools for Infrastructure Automation
In this section, let us look at the top Devops automation tools. Of course, Devops automation tools is only an integral part of the Devops strategy, to create a culture between the Dev and Ops, you need to follow a Devops implementation process to accelerate the delivery pipeline.
Infrastructure as a Code Tools
Ansible is a configuration management and orchestration tool. It helps to provide continuous integration and continuous delivery with zero downtime. With the help of this universal language, Ansible offers a simple, user-friendly IT automation that automates the network systems and supports a centralized deployment.
Uses of Ansible Tool:
Supports multi-tier deployments
No need any coding knowledge
Simple to Learn with easy flow of language
Gives insights about how systems are interrelated with each other
It provides a reliable and secure tool
Real-Time Example: NASA
Let’s look at a real-time example where they have utilized the Ansible effectively.
NASA planned to transfer 65 core applications from traditional data-center in to cloud AWS environment. But, due to lack of centralized management the entire process became cumbersome where even a simple patching took several days to implement.
To overcome these challenges, NASA adopted Ansible tool to make the process more streamlined with quick deployments and easy to use User interfaces.
Website updation (nasa.gov) reduced from 60 mins to 5 mins!
Security patching reduced drastically from multiple days to just 45 mins!!
Puppet is a ruby-based configuration tool with a lot of pre-built modules that helps to automate the infrastructure efficiently. It manages the infrastructure-as-a-code and the required configurations are automatically initiated.
Puppet is exclusively developed for System Administrators, with a puppet agent configured on all the server system. The server in turn extracts the compiled module and then instantly installs the software packages as per the module information.
Uses of Puppet Tool:
Provides effective collaboration between QA, Development & Operations Team led to transparency and faster deployments.
The task-based approach helped to build a high software quality with zero downtime.
Accurate & predictive workflows created a critical decision making and dynamic business operations.
Real-Time Example: Merrill Corporation
Merrill Corporation, a US-based IT services company, faced a challenge to migrate all of their critical data to the cloud environment in Microsoft Azure environment. The process was slow , inconsistent and unmanageable.
With implementing Puppet Enterprise, Merrill Corporation increased their overall efficiency with quicker deployments paving way to focus on larger business objectives.

Chef is one of the best cloud infrastructure automation tools. The basic function of Chef is the specific configuration of the centralized server is automatically updated to all the related nodes. This highly customizable tool gives the historical data that helps in project management processes.
ChefDK, the chef development kit, offers an additional efficiency testing tools. Chef workstation, chef server, node and Chef client are the important elements of Chef. For a developer team, Chef is the better choice or if your team are from System administration background then Puppet is right option.
Uses of Chef Tool:
Intelligent operations designs – used to alter only when there’s any deviation within a system
Easy, human-readable configuration policies
Reduces Operational expenses
Real-Time Example: Facebook
Before automation, Facebook found integrating each 10 k sized clusters nodes with their internal systems extremely impossible. But after the implementation of Chef, Facebook seamlessly automated the system configuration with massive scalability & without changing the workflow.
