How CI/CD Cut Costs & Time for a Leading Chatbot Company?

Introduction

At our company, we’re all about making automation easy and effective for our clients, helping them become more efficient and scalable. With deep expertise in infrastructure as code, configuration management, and CI/CD pipeline automation, which means we know how to streamline operations and cut down deployment times. Recently, we partnered with Chatbot Support Company, a company that was struggling to deploy customer support chatbots for its growing client base of over 100 companies.

Their traditional deployment approach was labor-intensive—it required multiple teams(Engineering, Infra Operations, DevOps team, Testing, Business Operations) and a lot of manual work to set up individual environments for each client. This method was not only time-consuming—taking 2-3 days per client—but it also left room for errors, making it difficult for the company to scale and meet the increasing demands of its customers. That’s when they reached out to us for a solution that would not only automate their infrastructure setup but also enhance the reliability and speed of their deployment pipeline.

To address these challenges, we implemented a comprehensive automated solution:

Infrastructure Automation with Terraform: We used Terraform to manage everything as code, automating the creation of Azure resources and ensuring consistency and scalability across environments. Specifically, we created:
- Virtual Machines (VMs): Configured with different operating systems, sizes, and storage options.
- Resource Group: To organize and manage related Azure resources.
- Virtual Network (VNet) and Subnets: For network segmentation and isolation.
- Network Security Groups (NSGs): To control inbound and outbound traffic to the VMs.
- Public IP Addresses: To enable external access to the VMs.
- Network Interfaces: To connect the VMs to the virtual network and public IPs.

If these resources already existed, they were reused; otherwise, Terraform created them from scratch. This ensured that each client’s environment was consistent, scalable, and easily repeatable.

Configuration Management with Ansible: Ansible helped us automate the installation and configuration of critical software across environments. We used it to manage the setup of Java, Tomcat, and MySQL, ensuring these services were consistently configured. Additionally, Ansible was used to configure system settings such as File Limits, Rsyslog, NCPA, Swap, and TCP services, reducing errors and maintaining uniformity across environments.
Deployment Pipeline Automation with GitHub Actions and Jenkins: We combined the power of GitHub Actions and Jenkins to orchestrate the entire deployment process. GitHub Actions handled the integration and automation of the code repository, triggering workflows on code changes, while Jenkins was used to streamline the CI/CD pipeline, automating the build, test, and deployment stages. Jenkins also adjusted deployments to fit the needs of different environments, ensuring everything worked correctly for each stage.

This integrated approach significantly reduced manual intervention, enabling the deployment of environments quickly and consistently, ultimately improving the ability to scale and serve clients effectively.

In this article, we’ll dive into the challenges faced, how we leveraged Terraform, Ansible, GitHub Actions, and Jenkins to automate the deployment process, and the real-world benefits this brought to operations.

Problem Statement

In today’s fast-paced tech environment, companies are under constant pressure to deploy software quickly, efficiently, and without errors. For a client with over 100 companies relying on their customer support chatbots, the manual deployment process was a significant bottleneck. This process involved multiple teams and several steps, each prone to delays and errors, making it increasingly difficult for the company to scale and meet the demands of its expanding client base.

Inconsistent Setups: The manual process led to differences in the client’s environment. Since there were no standard templates, each setup was slightly different, which caused problems during deployment and maintenance. Without clear standards, fixing issues and scaling the setup became more complicated and time-consuming.
Long Setup Time: It took about 2-3 days on average to complete the setup for this client. The process involved several teams—DevOps, database admins, network engineers, and developers—all of whom needed to coordinate their work. For example, after the database team finished their part, the web team had to set up the web server. This often led to delays due to compatibility issues and configuration mismatches.
Impact on Project Timelines: The delays in setting up the environment affected the project’s timelines. Go-live dates were pushed back, and resources were stretched thin as team members worked on multiple setups at once. This inefficiency created bottlenecks and made it hard to meet deadlines, especially during busy periods. The lack of automation also made it hard to quickly scale the setup or add new features.
Maintenance Problems: The unique nature of each setup made ongoing maintenance difficult. Fixing issues required a lot of effort because each environment was different. This often led to longer downtimes and frustration for both the client and our team.

Our Solution

1. Dramatic Reduction in Deployment Time

How We Did It:

Terraform Modules for Consistency: We implemented reusable Terraform modules to create standardized Azure resources like virtual networks, storage accounts, and compute instances. This allowed for the rapid provisioning of infrastructure across all environments with minimal manual intervention.
Ansible Playbooks for Configuration Automation: We used Ansible to automate the software configuration, including the installation of dependencies like Java, MySQL, and system configurations such as network settings, file limits, and security hardening. These playbooks were executed across all environments simultaneously, eliminating the need for manual installation on each server.
Pipeline Automation with GitHub Actions and Jenkins: Jenkins automated the testing, building, and deployment phases, while GitHub Actions was configured to automatically trigger this process upon code commits. This ensured that infrastructure provisioning and software configuration were fully automated from the start of the commit process.

Impact:

Terraform: Reduced time spent on environment setup by 85% by enabling infrastructure creation in minutes instead of hours.
Ansible: Minimized the risk of misconfigurations by 90%, as the same playbooks were used across all environments, ensuring consistency.

CI/CD Pipeline: Reduced deployment time from 2-3 days to under 30 minutes by orchestrating the entire process, from testing code changes to provisioning infrastructure and applying configurations, all without manual intervention.

2. Reduction in Human Errors

How We Did It: By automating manual steps with Terraform and Ansible, we removed the potential for human errors in infrastructure setup and software configuration. Ansible’s playbooks ensured consistent configurations across environments, while Terraform provided a reliable infrastructure foundation.

Impact: The rate of human errors in deployments decreased by 95%, from an error rate of 70% due to manual processes to less than 5%. This reduction saved approximately 8 hours per deployment that would have otherwise been spent on error correction and troubleshooting, significantly improving deployment reliability and efficiency.

3. Cost Savings in Operational Expenses

How We Did It: The transition to an automated pipeline involved implementing Terraform for infrastructure management, Ansible for configuration, and Jenkins along with GitHub Actions for continuous integration and deployment.
