In today’s fast-paced software development landscape, automation tools have become crucial for improving efficiency, reducing errors, and speeding up development cycles. Jenkins, a popular open-source automation server, is one of the most widely used tools for automating the various stages of the software development lifecycle, including building, testing, and deploying software. On the other hand, Amazon Web Services (AWS) EC2 (Elastic Compute Cloud) provides scalable, flexible cloud computing resources that allow developers to run applications and workloads with the ability to scale according to demand.

Integrating Jenkins with AWS EC2 can bring numerous benefits to development teams, including improved scalability, cost-efficiency, and automation of deployment tasks. By leveraging the power of Jenkins and AWS EC2 together, teams can streamline their CI/CD (Continuous Integration/Continuous Deployment) pipelines and quickly adapt to changing demands in a dynamic cloud environment. In this guide, we will explore how Jenkins integrates with AWS EC2, the benefits of this integration, and provide an overview of the steps involved in setting up and configuring Jenkins to work with AWS EC2 instances.

What is Jenkins?

Jenkins is an open-source automation tool primarily used for continuous integration and continuous delivery (CI/CD). Its main purpose is to automate tasks related to building, testing, and deploying software, making it an essential tool in modern DevOps practices. Jenkins provides a vast ecosystem of plugins that integrate with a variety of tools, technologies, and services, which makes it versatile and adaptable to different workflows and environments.

Jenkins enables developers to automate the process of:

Building Software: Jenkins can pull code from version control systems like Git, compile it, and build software packages automatically.
Running Tests: Jenkins can run unit tests, integration tests, and performance tests as part of the build process to ensure code quality.
Deploying Applications: Once the software passes tests, Jenkins can deploy it to staging or production environments, minimizing manual intervention and ensuring consistency across deployments.
Monitoring: Jenkins can be configured to monitor the status of builds, tests, and deployments and send alerts in case of failures or issues.

Jenkins offers various features that make it ideal for automation, such as:

Extensibility: Jenkins has a plugin-based architecture, allowing you to extend its capabilities by integrating with numerous third-party tools and services.
Distributed Builds: Jenkins supports distributing build tasks across multiple machines (called agents) to speed up build times.
Pipeline as Code: Jenkins supports defining CI/CD workflows as code using Jenkinsfile, which allows versioning of the pipeline configuration itself.

Despite its versatility and wide usage, Jenkins requires underlying infrastructure to run. For many teams, deploying Jenkins on cloud-based platforms like AWS EC2 provides additional scalability and flexibility.

What is AWS EC2?

Amazon Elastic Compute Cloud (EC2) is one of the most important services offered by AWS. It provides resizable compute capacity in the cloud, allowing users to run virtual machines, referred to as “instances.” These instances can run various operating systems (Linux, Windows, etc.), and AWS offers multiple instance types that can be tailored for different workloads, from simple web servers to resource-heavy applications.

Key features and advantages of AWS EC2 include:

Scalability: EC2 instances can be dynamically scaled based on application demand. You can launch or terminate instances as needed, allowing you to easily adjust to changing traffic or workload requirements.
Cost-Effectiveness: AWS EC2 operates on a pay-as-you-go pricing model, where users only pay for the resources they consume. You can choose from on-demand instances, reserved instances, or spot instances to optimize costs.
Variety of Instance Types: AWS EC2 provides a wide selection of instance types optimized for different purposes, such as compute-intensive, memory-optimized, or storage-intensive applications.
Flexibility: You can install and configure any software, application, or service on EC2 instances, making it highly adaptable to various use cases.
Integration with AWS Services: EC2 integrates seamlessly with other AWS services such as S3 (Simple Storage Service), RDS (Relational Database Service), and CloudWatch, enabling users to build highly scalable and fault-tolerant architectures.

When Jenkins is integrated with EC2, you can take advantage of the flexibility and scalability of the cloud to run Jenkins in a way that is efficient, cost-effective, and easily adjustable to project needs. For example, by using EC2, Jenkins can automatically provision instances to handle different build or testing requirements, scale up resources when the workload increases, and scale down when the load decreases. This dynamic scalability is a significant advantage for continuous integration environments, which often need to handle fluctuating levels of resource demand.

Why Integrate Jenkins with AWS EC2?

There are several reasons why integrating Jenkins with AWS EC2 is a smart decision for modern software development teams:

1. Scalability

One of the main advantages of using AWS EC2 with Jenkins is the ability to scale resources dynamically based on the workload. As Jenkins jobs (builds, tests, deployments) are triggered, additional EC2 instances can be spun up automatically to handle the load. For instance, when running multiple jobs in parallel or handling more complex tasks, Jenkins can provision additional EC2 instances to maintain performance and reduce bottlenecks. Similarly, when the workload reduces, Jenkins can deallocate EC2 instances to save on costs.

2. Cost Efficiency

AWS EC2’s pay-as-you-go model ensures that you only pay for the resources you actually use. This flexibility makes it an ideal platform for running Jenkins. Instead of maintaining on-premise infrastructure for Jenkins, where hardware is often underutilized, running Jenkins on EC2 means you only pay for the time you use the resources. Additionally, AWS offers various pricing models, such as spot instances and reserved instances, which can help reduce costs further. This can significantly lower the total cost of ownership for Jenkins servers.

3. Automation of Provisioning and Deployment

By integrating Jenkins with AWS EC2, teams can automate not only the build and deployment processes but also the provisioning and configuration of cloud infrastructure. Jenkins, with its EC2 plugin, can launch new EC2 instances as Jenkins agents to run specific tasks such as builds or tests. The provisioning and de-provisioning of EC2 instances can be automated as part of Jenkins pipelines, which reduces the manual effort involved in managing infrastructure.

4. Increased Efficiency and Reliability

The combination of Jenkins’ automation and EC2’s cloud infrastructure ensures that the CI/CD pipeline runs smoothly and efficiently. Developers do not need to worry about managing the underlying infrastructure as AWS handles the provisioning, scaling, and management of EC2 instances. Additionally, using AWS EC2 for Jenkins ensures high availability and fault tolerance. If an instance fails, Jenkins can automatically provision a new one, minimizing downtime and ensuring continuous delivery of software.

5. Flexibility in Configuration

AWS EC2 provides a wide range of instance types with varying levels of computing power, memory, and storage, making it easy to choose the right instance type for each Jenkins job. For example, resource-heavy tasks like running large test suites or compiling large codebases can be run on powerful EC2 instances, while lightweight tasks can be executed on smaller, cost-effective instances. This flexibility allows Jenkins to perform optimally across different tasks without overprovisioning resources, leading to better utilization of cloud infrastructure.

Integrating Jenkins with AWS EC2 offers significant advantages in terms of scalability, cost-efficiency, automation, and performance. By leveraging the capabilities of AWS EC2, Jenkins can run on a flexible, on-demand cloud infrastructure that dynamically adjusts based on workload requirements. This integration enables development teams to automate their build, testing, and deployment pipelines while ensuring that they can scale their resources as needed without incurring unnecessary costs.

Setting Up Jenkins on AWS EC2 Instances

Now that we’ve covered the basics of what Jenkins and AWS EC2 are and the benefits of integrating them, we’ll walk through the steps of setting up Jenkins on an AWS EC2 instance. This will enable you to take advantage of the scalability, flexibility, and cost-efficiency that AWS EC2 provides.

This process can be broken down into a few main tasks: launching an EC2 instance, installing Jenkins, configuring the firewall and security settings, and ensuring that Jenkins is accessible. Below, we’ll guide you through each step in detail.

Launching an EC2 Instance for Jenkins

The first step is to launch an EC2 instance on AWS, which will act as the host for Jenkins. Follow these steps to launch the instance:

Create an AWS Account and Log in:
If you don’t have an AWS account, you will need to create one. Once your account is set up, log in to the AWS Management Console.
Navigate to the EC2 Dashboard:
In the AWS Management Console, go to the “EC2” service by selecting “Compute” from the main menu. Then, click on “Instances” to view your current instances and start the process of launching a new one.
Choose an Amazon Machine Image (AMI):
Choose an appropriate AMI for the instance. For Jenkins, a Linux-based AMI such as Amazon Linux 2 or CentOS is recommended. These Linux distributions are stable and well-supported for Jenkins installations.
Select an Instance Type:
For Jenkins, a small instance type such as t2.micro (eligible for the AWS Free Tier) or t2.small is sufficient for light workloads. However, if you expect higher workloads or need to run multiple Jenkins jobs concurrently, you can choose a more powerful instance type.
Configure Instance Details:
You can configure the number of instances, network settings, and IAM roles at this step. For a basic setup, the default settings should suffice. Make sure that the instance is launched within the correct VPC (Virtual Private Cloud).
Add Storage:
The default storage configuration is typically enough for Jenkins. However, if you expect to store large amounts of build artifacts or data, you may choose to add more storage.
Configure Security Group:
A security group acts as a virtual firewall for your EC2 instance. You must configure the security group to allow HTTP (port 80) and HTTPS (port 443) traffic, as well as Jenkins’ default port 8080.
- To do this, create an inbound rule that allows TCP traffic on port 8080.
- You can also add a rule that allows SSH (port 22) so you can connect to the instance via SSH. Make sure to restrict SSH access to your IP address for security purposes.
Review and Launch:
After configuring the instance, review your choices. If everything looks good, click “Launch”. During this step, you will need to create a new key pair to securely access the instance. Download the private key (.pem file) and store it in a safe location.

Once your instance is launched, it will appear on the EC2 dashboard. After the instance has been initialized (this may take a minute or two), you can proceed with the next steps to install Jenkins.

Installing Jenkins on the EC2 Instance

Now that you have launched an EC2 instance, the next step is to install Jenkins on the instance. We will use a CentOS-based instance as an example, but the process will be similar for other Linux distributions.

Connect to the EC2 Instance via SSH:
First, you need to connect to your EC2 instance using SSH. Open your terminal and run the following command, replacing <path_to_your_pem_file> with the path to your .pem key and <public_dns> with the public DNS of your EC2 instance:

php-template
Copy
ssh -i <path_to_your_pem_file> ec2-user@<public_dns>

After connecting, you should be logged into the EC2 instance and ready to proceed with the Jenkins installation.

Update the Instance:
It’s a good idea to update your instance to ensure that you’re working with the latest software packages. Run the following command:

sql
Copy
sudo yum update -y

Install Java:
Jenkins requires Java to run. For Jenkins 2.x, Java 8 or higher is recommended. Run the following command to install OpenJDK 11:

nginx
Copy
sudo yum install -y java-11-openjdk-devel

Add Jenkins Repository:
To install Jenkins, you need to add its repository to your system. Run the following commands to add the Jenkins repository:

swift
Copy
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat/jenkins.repo

sudo rpm –import https://pkg.jenkins.io/redhat/jenkins.io.key

Install Jenkins:
With the repository added, you can now install Jenkins using the following command:

nginx
Copy
sudo yum install -y jenkins

Start Jenkins:
Once Jenkins is installed, start the Jenkins service with the following command:

sql
Copy
sudo systemctl start jenkins

To ensure Jenkins starts automatically with the system, run:

bash
Copy
sudo systemctl enable jenkins

Check Jenkins Status:
To verify that Jenkins is running, use the following command:

lua
Copy
sudo systemctl status jenkins

If Jenkins is running correctly, you should see an active status message.

Configuring the Firewall and Security Group

Jenkins by default runs on port 8080. However, you need to configure your security group to allow inbound traffic on this port so that you can access Jenkins through a web browser.

Modify Inbound Rules:
Go to the EC2 dashboard and select your running instance. Under the “Security” section, click on the security group attached to your instance. Then, add an inbound rule to allow HTTP (port 8080) traffic from your desired IP address or the entire world, if necessary.

Access Jenkins:
Now that your instance is set up and the firewall is configured, open a web browser and enter the following URL:

cpp
Copy
http://<public_dns>:8080

Replace <public_dns> with the public DNS of your EC2 instance. This should bring up the Jenkins web interface.

Final Steps for Initial Setup

Once you access Jenkins in the browser, you will be prompted to unlock Jenkins by providing the initial admin password.

Retrieve the Admin Password:
To find the initial admin password, run the following command on your EC2 instance:

bash
Copy
sudo cat /var/lib/jenkins/secrets/initialAdminPassword

Complete Setup:
Copy the password and paste it into the prompt on the Jenkins setup page. After unlocking Jenkins, you can choose to install the suggested plugins, which will provide a basic set of tools to get started.
Create an Admin User:
After the plugins are installed, Jenkins will ask you to create your first admin user. Once that is done, you will have access to the Jenkins dashboard and be able to start creating Jenkins jobs and configuring your environment.

By following these steps, you have successfully installed Jenkins on an AWS EC2 instance, configured the firewall, and accessed the Jenkins web interface. This setup provides a solid foundation for automating software builds, tests, and deployments in a scalable, cost-effective cloud environment.

Integrating Jenkins with AWS EC2

Now that we have set up Jenkins on an AWS EC2 instance, the next step is to explore how to integrate Jenkins with AWS EC2 for enhanced scalability, automation, and efficiency. Integrating Jenkins with EC2 allows you to dynamically provision and manage EC2 instances for running Jenkins jobs, enabling automatic scaling and resource allocation based on job demand. This integration is particularly useful when you want to ensure that your Jenkins environment can handle varying workloads without compromising on performance.

In this part, we will discuss various methods for integrating Jenkins with AWS EC2, including using the AWS EC2 plugin, managing EC2 instances as Jenkins agents, and automating the provisioning and scaling of instances using Jenkins pipelines.

Using the AWS EC2 Plugin in Jenkins

One of the most straightforward ways to integrate Jenkins with AWS EC2 is by using the AWS EC2 Plugin. This plugin allows Jenkins to provision EC2 instances dynamically as build agents, which means Jenkins can scale the number of agents based on the number of jobs in the queue. The plugin can also be configured to terminate idle instances, ensuring efficient use of resources and reducing costs.

1. Installing the AWS EC2 Plugin:

To use the AWS EC2 plugin in Jenkins, you need to install it first:

Navigate to Manage Jenkins > Manage Plugins.
Go to the Available tab and search for the Amazon EC2 Plugin.
Select the plugin and click Install.

Once installed, you can configure Jenkins to launch EC2 instances as build agents.

2. Configuring the AWS EC2 Plugin:

After installing the plugin, you need to configure it to integrate with your AWS account and set up EC2 instances as Jenkins agents.

Go to Manage Jenkins > Configure System.
Scroll down to the Cloud section and click Add a new cloud.
Select Amazon EC2 from the drop-down list.
Fill in the AWS Access Key and Secret Key. You can create an IAM user in your AWS account and generate the access keys for this purpose. Ensure that the IAM user has the necessary permissions to create and manage EC2 instances.

3. Setting Up EC2 Instances as Jenkins Agents:

You can configure Jenkins to launch EC2 instances as agents by specifying the following settings:

AMI ID: Choose the Amazon Machine Image (AMI) ID for the EC2 instance. This could be a standard Linux-based AMI or a custom AMI with pre-installed software, including Jenkins agents.
Instance Type: Select the instance type, such as t2.micro, t2.small, or any other instance type that meets the resource requirements of your build tasks.
Key Pair: Select the SSH key pair to connect to the EC2 instance.
Security Group: Choose a security group that allows Jenkins to connect to the EC2 instance via SSH.
Instance Cap: Define the maximum number of EC2 instances Jenkins is allowed to launch based on the workload.

4. Defining Build Labels and Availability:

You can define labels for the EC2 instances to make sure specific types of builds are run on the right EC2 instances. For example, you might want certain jobs to run on instances with more memory or CPU power. Additionally, you can set up a maximum number of idle executors to control how many EC2 instances Jenkins should keep running for idle jobs.

5. Launching and Terminating EC2 Instances:

Once everything is set up, Jenkins will launch new EC2 instances as agents to execute build jobs. When jobs are finished, Jenkins can automatically terminate idle EC2 instances, helping to optimize costs by ensuring that instances are only running when necessary.

Managing EC2 Instances as Jenkins Agents

Managing EC2 instances as Jenkins agents provides flexibility in scaling your Jenkins environment. You can set up different configurations of EC2 instances based on the type of job, ensuring that you are optimizing resource usage.

1. Auto-Scaling with EC2:

One of the most powerful features of integrating Jenkins with AWS EC2 is auto-scaling. With Jenkins, you can automatically launch new EC2 instances to handle incoming jobs when the queue is full, and terminate instances when the jobs are completed. By doing so, you can ensure that the number of EC2 instances matches the demand for Jenkins jobs.

Auto-scaling can be set up by using AWS EC2’s Auto Scaling Groups along with the Jenkins EC2 plugin. This allows you to configure the number of instances to scale up or scale down based on the Jenkins workload.

Set up an Auto Scaling Group in AWS, specifying the minimum and maximum number of instances.
In Jenkins, configure the EC2 plugin to launch and connect to instances in the Auto Scaling group based on workload.
You can also configure Scaling Policies to automatically adjust the number of EC2 instances based on CPU utilization or other metrics.

2. Cost Optimization:

One of the advantages of running Jenkins on EC2 is the ability to optimize costs through dynamic provisioning. By scaling EC2 instances up or down based on demand, Jenkins can ensure that you are only using the resources you need. This reduces the cost of idle resources and ensures that the system is always operating efficiently.

Additionally, using spot instances can further reduce costs. Spot instances are unused EC2 instances that are available at a lower cost but may be terminated by AWS at any time. By leveraging Jenkins’ ability to launch and terminate EC2 instances on demand, you can take advantage of these lower-cost instances for your build jobs.

Automating EC2 Provisioning in Jenkins Pipelines

Jenkins Pipeline is a powerful feature that allows you to define a series of automated steps for building, testing, and deploying software in a pipeline. Jenkins pipelines can be written as code in a Jenkinsfile, which can be version-controlled along with your application code.

With AWS integration, Jenkins Pipeline can be used to automate the provisioning of EC2 instances for build or test environments dynamically. This is particularly useful for teams that want to spin up isolated environments for testing purposes or perform tasks like load testing that require scaling resources.

1. Using AWS SDK within Jenkins Pipeline:

Jenkins Pipeline scripts can leverage AWS SDK for Java, Python, or other languages to interact with AWS services, including EC2. By doing so, Jenkins can programmatically create, manage, and terminate EC2 instances as part of the CI/CD pipeline.

For example, the following pipeline script snippet demonstrates how to provision an EC2 instance, run tests, and terminate the instance afterward:

2. Dynamic Resource Allocation:

In addition to provisioning EC2 instances for running tests, you can also use Jenkins Pipeline to manage dynamic resource allocation. For instance, you can specify in your pipeline how much CPU and memory should be allocated to EC2 instances based on the nature of the tasks they need to run. This ensures that the infrastructure scales appropriately based on the job type.

Integrating Jenkins with AWS EC2 allows you to leverage the full power of cloud infrastructure for managing your CI/CD pipelines. The combination of Jenkins’ automation capabilities with AWS EC2’s scalability and flexibility provides an efficient and cost-effective solution for handling software builds, tests, and deployments.

In this section, we’ve covered the installation and configuration of the AWS EC2 plugin for Jenkins, the management of EC2 instances as Jenkins agents, and the use of Jenkins Pipeline to automate the provisioning and scaling of EC2 instances. These features empower teams to scale their Jenkins environment dynamically, optimize resources, and reduce infrastructure costs while maintaining high availability and performance.

Advanced Jenkins and AWS EC2 Integrations for CI/CD Pipelines

Now that we’ve established how to set up Jenkins on AWS EC2 and integrate it using plugins, let’s dive into advanced integrations and configurations to make the most of Jenkins running on AWS EC2 instances. This section will explore how to optimize your CI/CD pipelines, leverage advanced scaling, and automate various aspects of your infrastructure and deployments.

Advanced EC2 Scaling with Jenkins

The integration of Jenkins with AWS EC2 provides the opportunity to scale your Jenkins environment to match the load demands of your builds and tests. One of the most significant advantages of cloud infrastructure is the ability to automatically scale resources based on workload requirements, ensuring that you only use the resources you need, when you need them.

1. Dynamic Scaling with Auto Scaling Groups:

Jenkins can integrate with EC2’s Auto Scaling Groups to automatically scale your EC2 instances based on the demand for build and deployment tasks. The Auto Scaling service in AWS allows you to define a minimum, maximum, and desired number of instances in an Auto Scaling group. This setup enables Jenkins to scale the number of EC2 instances up or down based on predefined criteria, such as CPU utilization or the number of queued jobs.

For example:

When there is a high number of Jenkins jobs waiting to be processed, the Auto Scaling group will launch additional EC2 instances to handle the load.
When the load decreases, the group will automatically terminate idle instances to save on costs.

By using Amazon CloudWatch to monitor the health and performance of EC2 instances, Jenkins can be configured to respond to high-load events, trigger scaling actions, and ensure that the Jenkins environment is always optimized for the workload.

2. Using AWS Lambda for Serverless Scaling:

Another advanced approach is using AWS Lambda in conjunction with Jenkins for serverless scaling. Lambda allows you to run code in response to events such as the arrival of new Jenkins jobs. By leveraging Lambda, you can automate the process of provisioning and terminating EC2 instances on demand, without needing to manage the instances yourself.

For instance:

Lambda can be triggered whenever a new build is added to the queue in Jenkins, automatically provisioning an EC2 instance to handle the job.
Once the job is complete, Lambda can again be triggered to terminate the EC2 instance, ensuring that resources are efficiently managed without manual intervention.

This serverless approach minimizes overhead and makes it easier to scale Jenkins on AWS EC2 while only paying for the resources you need at any given moment.

3. Elastic Load Balancing (ELB):

In some cases, Jenkins jobs may require handling a large number of concurrent build tasks. To distribute traffic across multiple EC2 instances running Jenkins agents, you can use Elastic Load Balancing (ELB). ELB helps ensure that incoming traffic is distributed evenly across multiple EC2 instances, preventing any single instance from being overwhelmed.

Jenkins can use an ELB to distribute Jenkins jobs to multiple EC2 instances, ensuring that each job is handled by an available agent. ELB will automatically reroute traffic in case of instance failure, providing fault tolerance for Jenkins environments.

Automating EC2 Instance Provisioning with Jenkins Pipelines

Jenkins Pipelines allow you to define your CI/CD process as code, enabling version control and easy modification of build, test, and deployment workflows. When integrated with AWS EC2, Jenkins Pipelines can be used to automate EC2 instance provisioning, configuration, and decommissioning during various stages of the CI/CD pipeline.

1. Using AWS SDK for EC2 Provisioning:

The AWS SDK can be integrated into Jenkins pipelines to automate the creation and configuration of EC2 instances as part of the CI/CD process. For example, you can define a pipeline that provisions EC2 instances, runs a set of tests, and then terminates the instances when they are no longer needed.

Below is a sample Jenkins pipeline code snippet that provisions an EC2 instance and runs a build job:

The Jenkins pipeline provisions a new EC2 instance using the AWS SDK, runs tests on the instance, and terminates it after the tests are completed.

2. Integrating with EC2 Auto Scaling:

For more advanced workflows, you can configure Jenkins pipelines to automatically scale your infrastructure using EC2 Auto Scaling groups. Jenkins can trigger Auto Scaling events based on the load, such as launching additional EC2 instances when the number of queued jobs increases. This makes the pipeline more dynamic and responsive to changing workloads, ensuring that Jenkins jobs are executed in a timely manner.

For instance, you can set up a Jenkins job that, depending on the current number of queued jobs, automatically scales your EC2 infrastructure to meet the demand.

Integrating Jenkins with AWS Services Beyond EC2

While EC2 provides the core compute resources for running Jenkins jobs, AWS offers other services that can complement Jenkins and further optimize the CI/CD process. Here are some AWS services you can integrate with Jenkins to extend its capabilities:

1. Amazon S3 for Artifact Storage:

Jenkins can be configured to store build artifacts in Amazon S3. Once a build is complete, Jenkins can automatically upload build artifacts to S3 for later use or deployment. By using S3, you can store large artifacts such as compiled binaries, log files, and configuration files in a scalable and cost-effective manner.

2. AWS CodeDeploy for Automated Deployments:

You can integrate AWS CodeDeploy with Jenkins to automate application deployments to EC2 instances or other AWS services. CodeDeploy can handle complex deployment tasks such as rolling updates, blue/green deployments, and monitoring deployment status. Jenkins can trigger CodeDeploy as part of the pipeline, ensuring that your deployments are automated and consistent.

3. Amazon RDS for Database Testing:

If your application depends on a database, you can use Amazon RDS to provision database instances for Jenkins to run integration tests. Jenkins pipelines can automate the creation of RDS instances, execute tests on those instances, and clean up the resources once the tests are complete.

Integrating Jenkins with AWS EC2 not only allows you to automate the CI/CD process but also provides scalability and flexibility in handling dynamic workloads. With Jenkins running on EC2 instances, you can provision resources on demand, ensuring that your CI/CD pipeline operates efficiently while minimizing resource wastage. By leveraging AWS EC2, Auto Scaling, Lambda, and other AWS services, you can further optimize your infrastructure, improve automation, and reduce costs.
