# 🚀 AWS CodePipeline | Jenkins vs AWS CodePipeline | Open Source vs AWS Managed

# 📖 Introduction

CI/CD is one of the most important parts of modern DevOps.

When developers write and update application code, organizations need a reliable way to:

```text
Write Code
    ↓
Integrate Code
    ↓
Build
    ↓
Test
    ↓
Deliver
```

Doing all these activities manually can be time-consuming and difficult to maintain.

This is where CI/CD automation tools come into the picture.

One of the most popular open-source tools used for CI/CD is **Jenkins**.

AWS also provides its own managed CI/CD services, including:

*   **AWS CodePipeline**
    
*   **AWS CodeBuild**
    
*   **AWS CodeDeploy**
    

In this blog, our main focus is **AWS CodePipeline** and how it compares with **Jenkins**.

The main question we will answer is:

> **What is the difference between using an open-source CI/CD tool like Jenkins and a managed AWS service like CodePipeline?**

# 🚀 What is CI/CD?

CI/CD represents practices used to automate software integration, testing, delivery, and deployment.

CI means:

> **Continuous Integration**

CD can refer to:

> **Continuous Delivery**

or:

> **Continuous Deployment**

The basic idea is to automate the software delivery process instead of performing every step manually.

A simplified workflow looks like:

```text
Developer
    ↓
Source Code
    ↓
CI
    ↓
Build
    ↓
Test
    ↓
CD
    ↓
Delivery / Deployment
```

* * *

# 🔄 Continuous Integration

**Continuous Integration (CI)** is the practice of frequently integrating code changes and automatically validating them.

For example:

```text
Developer
    ↓
Code Change
    ↓
Git Push
    ↓
Build
    ↓
Test
```

The objective is to detect problems early.

Instead of waiting until the end of a project to integrate everyone's code, developers continuously integrate their changes.

* * *

# 🚚 Continuous Delivery

**Continuous Delivery (CD)** focuses on keeping the application ready for delivery.

A simplified flow can be:

```text
Code
 ↓
Build
 ↓
Test
 ↓
Package
 ↓
Ready for Delivery
```

The release process can then move toward deployment.

* * *

# ⚡ Continuous Deployment

Continuous Deployment takes automation further.

When the required checks pass, the application can automatically be deployed.

```text
Code
 ↓
Build
 ↓
Test
 ↓
Deploy
```

The exact implementation depends on the organization's CI/CD process.

* * *

# 🧠 What is CI/CD Orchestration?

This is the most important concept for understanding **Jenkins vs AWS CodePipeline**.

A CI/CD pipeline can contain multiple stages.

For example:

```text
Source
   ↓
Build
   ↓
Test
   ↓
Delivery
```

Now imagine that different tools are responsible for these activities.

Something needs to coordinate the entire process.

This coordination is called **orchestration**.

* * *

# 🎯 What Does a CI/CD Orchestrator Do?

An orchestrator manages the sequence of activities in the pipeline.

For example:

```text
Step 1
Source
   ↓
Step 2
Build
   ↓
Step 3
Test
   ↓
Step 4
Delivery
```

The orchestrator determines:

*   What should run first
    
*   What should run next
    
*   Whether the next stage should execute
    
*   What should happen when a stage succeeds
    
*   What should happen when a stage fails
    
*   Which service should perform a particular task
    

Both Jenkins and AWS CodePipeline can play this orchestration role.

* * *

# 🔧 What is Jenkins?

Jenkins is an open-source automation server commonly used to implement CI/CD pipelines.

Jenkins can coordinate different stages of a software delivery workflow.

For example:

```text
Developer
    ↓
Source Repository
    ↓
Jenkins
    ↓
Build
    ↓
Test
    ↓
Delivery
```

Jenkins is not simply a build tool.

It can act as the central orchestrator that controls the overall CI/CD workflow.

* * *

# 🧩 Jenkins as a CI/CD Orchestrator

Consider this workflow:

```text
Source Code
     ↓
    Jenkins
     ↓
    Build
     ↓
    Test
     ↓
   Delivery
```

Jenkins can control the sequence.

For example:

```text
If Build succeeds
       ↓
Run Tests

If Tests succeed
       ↓
Continue to Delivery
```

If a stage fails:

```text
Build
  ↓
FAIL
  ↓
Pipeline Stops
```

This is the orchestration responsibility.

* * *

# 🖥 Jenkins and Infrastructure Management

One of the important differences between Jenkins and AWS CodePipeline is **infrastructure management**.

Jenkins is open source.

That means the software is available for you to install and operate.

For example, an organization may run Jenkins on a server:

```text
Server
   ↓
Jenkins
   ↓
CI/CD Pipeline
```

The organization becomes responsible for maintaining the infrastructure on which Jenkins runs.

* * *

# 👷 Jenkins Worker Nodes / Agents

Jenkins commonly uses worker nodes, also called agents, to execute jobs.

A simplified architecture looks like:

```text
             Jenkins Controller
                     |
          ┌──────────┼──────────┐
          ↓          ↓          ↓
       Worker 1   Worker 2   Worker 3
          ↓          ↓          ↓
        Build      Test      Other Jobs
```

The workers perform the actual tasks assigned by Jenkins.

For example:

```text
Jenkins
   ↓
Worker Node
   ↓
Build Application
   ↓
Run Tests
```

* * *

# ⚠️ Why Worker Management Matters

When using Jenkins, the team may need to think about:

*   How many workers are required
    
*   Worker capacity
    
*   Worker availability
    
*   Worker configuration
    
*   Worker maintenance
    
*   Scaling workers when workload increases
    

For example:

```text
Small Workload
      ↓
1 Worker
```

But if many pipelines run simultaneously:

```text
Large Workload
      ↓
Multiple Workers
      ↓
More Infrastructure Management
```

This is one of the operational responsibilities associated with a self-managed Jenkins setup.

* * *

# ☁️ What is AWS CodePipeline?

**AWS CodePipeline** is an AWS managed service used to automate and orchestrate software release workflows.

Instead of managing your own CI/CD orchestration server, AWS provides the managed CodePipeline service.

A simplified architecture is:

```text
Source
   ↓
AWS CodePipeline
   ↓
AWS CodeBuild
   ↓
AWS CodeDeploy
```

The important point is:

> **CodePipeline acts as the orchestrator.**

* * *

# 🧠 AWS CodePipeline as a Managed Orchestrator

CodePipeline can coordinate different stages of the CI/CD process.

For example:

```text
Source
   ↓
CodePipeline
   ↓
Build
   ↓
Test
   ↓
Delivery
```

The actual work can be performed by other services.

For example:

```text
                 AWS CodePipeline
                        |
          ┌─────────────┴─────────────┐
          ↓                           ↓
      CodeBuild                   CodeDeploy
          ↓                           ↓
      CI Activities              CD Activities
```

So the responsibilities are separated.

* * *

# 🔨 AWS CodeBuild for CI

AWS CodeBuild can be used for the CI part of the workflow.

For example:

```text
CodePipeline
     ↓
CodeBuild
     ↓
Build
     ↓
Test
```

CodeBuild performs the actual build and test-related work.

CodePipeline coordinates when CodeBuild should run.

This gives us:

```text
CodePipeline
=
Orchestration
```

and:

```text
CodeBuild
=
Build + CI Activities
```

* * *

# 🚀 AWS CodeDeploy for CD

AWS CodeDeploy can be used for deployment-related activities.

The architecture can be:

```text
CodePipeline
     ↓
CodeBuild
     ↓
CodeDeploy
```

Here:

```text
CodePipeline
     ↓
Orchestrates
```

while:

```text
CodeBuild
     ↓
CI / Build
```

and:

```text
CodeDeploy
     ↓
CD / Deployment
```

This separation of responsibilities is important when understanding the AWS managed approach.

* * *

# 🏗 AWS Managed CI/CD Architecture

The AWS managed approach can be represented as:

```text
                       Developer
                           ↓
                      Source Code
                           ↓
                  ┌─────────────────┐
                  │ AWS CodePipeline│
                  │  Orchestrator   │
                  └─────────────────┘
                           ↓
                    ┌─────────────┐
                    │ CodeBuild   │
                    │     CI      │
                    └─────────────┘
                           ↓
                    ┌─────────────┐
                    │ CodeDeploy  │
                    │     CD      │
                    └─────────────┘
```

The important concept is that AWS provides managed services for different parts of the workflow.

* * *

# 🔄 Jenkins Approach vs AWS Managed Approach

Let's compare the two approaches.

## Jenkins

```text
Source
   ↓
Jenkins
   ↓
Worker Node
   ↓
Build
   ↓
Test
   ↓
Delivery
```

The organization manages the Jenkins infrastructure.

* * *

## AWS CodePipeline

```text
Source
   ↓
AWS CodePipeline
   ↓
AWS CodeBuild
   ↓
AWS CodeDeploy
```

AWS manages the underlying CodePipeline service.

The user focuses more on configuring the pipeline and connecting the required services.

* * *

# ⚖️ Jenkins vs AWS CodePipeline

The biggest difference can be understood through this comparison:

| Area | Jenkins | AWS CodePipeline |
| --- | --- | --- |
| Type | Open Source | AWS Managed |
| Role | CI/CD Orchestrator | CI/CD Orchestrator |
| Infrastructure | User-managed | AWS-managed |
| Worker Management | Usually required | No Jenkins-style worker management |
| Flexibility | Very high | More AWS-oriented |
| Platform Support | Broad | More AWS-centric |
| Multi-Cloud | Strong | More platform-restricted |
| Maintenance | More responsibility | Less infrastructure responsibility |
| Scaling Infrastructure | User responsibility | Managed by AWS service |
| CI Service | Jenkins can execute CI | CodeBuild can provide CI |
| CD Service | Jenkins can invoke deployment | CodeDeploy can provide CD |
| Management Model | Self-managed | Managed |
| Pricing Model | Open-source software + infrastructure costs | AWS service usage / pay-as-you-go model |

* * *

# 🆚 Open Source vs AWS Managed

Now let's understand the main concept behind this comparison.

* * *

# 🔓 Open Source Model — Jenkins

Jenkins is open-source software.

The basic idea is:

```text
Download / Install
       ↓
Configure
       ↓
Maintain
       ↓
Run CI/CD
```

You have significant control over the environment.

This can provide a high level of flexibility.

But with greater control comes greater responsibility.

You may need to manage:

```text
Jenkins
   ↓
Infrastructure
   ↓
Workers
   ↓
Configuration
   ↓
Maintenance
```

* * *

# ☁️ AWS Managed Model — CodePipeline

AWS CodePipeline is a managed AWS service.

The basic idea is:

```text
Create Pipeline
       ↓
Configure Stages
       ↓
Connect Services
       ↓
Run Pipeline
```

You don't need to manage a Jenkins controller or Jenkins worker infrastructure for CodePipeline.

AWS manages the underlying CodePipeline service infrastructure.

Therefore:

```text
Managed Service
        ↓
Less Infrastructure Management
```

* * *

# 🧠 Control vs Management

This is an important way to understand the difference.

### Jenkins

```text
More Control
     +
More Flexibility
     +
More Management
```

### CodePipeline

```text
Managed Service
     +
Less Infrastructure Management
     +
More AWS-Centric
```

There is a trade-off.

More control generally means more responsibility.

More managed infrastructure generally means less infrastructure management, but potentially more platform dependency.

* * *

![](https://cdn.hashnode.com/uploads/covers/66fecde7cb0abd844c1a2f3c/7fa7faed-527c-44ff-801f-c6ef79c7034f.png align="center")

# 🌍 Jenkins and Multi-Cloud Flexibility

One major advantage of Jenkins is its flexibility.

Jenkins can be used with different environments.

For example:

```text
                 Jenkins
                    |
        ┌───────────┼───────────┐
        ↓           ↓           ↓
       AWS        Azure         GCP
```

This can be useful when an organization works across multiple cloud providers.

Jenkins is not limited to one cloud platform.

* * *

# ☁️ AWS CodePipeline and Platform Dependency

AWS CodePipeline is designed as part of the AWS ecosystem.

It can integrate with external source providers and other supported services, but its biggest strength is its AWS integration.

For example:

```text
AWS CodePipeline
       ↓
AWS CodeBuild
       ↓
AWS CodeDeploy
```

This is very convenient when an organization is already heavily invested in AWS.

However, this can also mean that the architecture becomes more closely tied to AWS services.

* * *

# 🔒 Platform Restriction vs Flexibility

This gives us a simple comparison:

### Jenkins

```text
Jenkins
  ↓
AWS
Azure
GCP
Other Platforms
```

### AWS CodePipeline

```text
CodePipeline
     ↓
AWS Ecosystem
     ↓
AWS Services
```

Therefore:

> **Jenkins generally provides more platform flexibility, while CodePipeline provides a more AWS-centric managed experience.**

* * *

# 💰 Pay-As-You-Go Managed Experience

Another important difference is the service model.

AWS CodePipeline follows the AWS managed-service model, where you pay according to applicable AWS usage and pricing.

This is often described as:

> **Pay-as-you-go**

You don't purchase and maintain a Jenkins server just to run the orchestration software.

Instead, you use the AWS managed service.

* * *

# 💡 Important Point About "Free" Jenkins

Jenkins being open source does not mean the entire CI/CD environment costs nothing.

The Jenkins software itself is open source, but the infrastructure required to operate it can have costs.

For example:

```text
Jenkins Software
       ↓
Server
       ↓
Worker Nodes
       ↓
Storage
       ↓
Maintenance
```

There can be infrastructure and operational costs.

So the comparison should not simply be:

```text
Jenkins = Free
CodePipeline = Paid
```

A better comparison is:

```text
Jenkins
=
Open Source Software
+
Infrastructure
+
Management
+
Maintenance
```

versus:

```text
CodePipeline
=
Managed AWS Service
+
Usage-Based Pricing
+
Less Infrastructure Management
```

* * *

# 🛠 Infrastructure Management Comparison

Let's make the difference very simple.

## Jenkins

```text
                    Jenkins
                       ↓
              Infrastructure
                       ↓
                Worker Nodes
                       ↓
                 CI/CD Jobs
```

You need to manage the environment.

* * *

## CodePipeline

```text
                  CodePipeline
                       ↓
                AWS Managed Service
                       ↓
                 CodeBuild / Build
                       ↓
                CodeDeploy / CD
```

AWS manages the underlying CodePipeline infrastructure.

* * *

# 📈 Scaling Comparison

## Jenkins

Suppose you have many jobs running at the same time.

```text
Jenkins
   ↓
Worker 1
Worker 2
Worker 3
Worker 4
```

As the workload grows, you may need more workers.

This introduces additional infrastructure management.

* * *

## CodePipeline

With CodePipeline, you don't manage Jenkins-style worker nodes for the orchestration service.

AWS manages the underlying service infrastructure.

The focus shifts from:

```text
How do I maintain my CI/CD servers?
```

toward:

```text
How should my pipeline work?
```

* * *

# 🔧 Maintenance Comparison

## Jenkins

You may need to manage:

*   Jenkins installation
    
*   Jenkins upgrades
    
*   Worker nodes
    
*   Worker capacity
    
*   Infrastructure
    
*   Configuration
    

* * *

## CodePipeline

AWS manages the underlying CodePipeline service.

Your main responsibility becomes configuring:

*   Source
    
*   Pipeline stages
    
*   Actions
    
*   Build integration
    
*   Deployment integration
    

This can significantly reduce infrastructure management.

* * *

# 🎯 When Should You Choose Jenkins?

Jenkins can be a strong choice when:

### You Need Maximum Flexibility

If your organization requires highly customized CI/CD workflows, Jenkins gives you significant control.

* * *

### You Work Across Multiple Platforms

For example:

```text
AWS
+
Azure
+
GCP
```

Jenkins can provide a common orchestration layer.

* * *

### You Want an Open-Source Solution

Jenkins is open source and has a large ecosystem.

* * *

### You Want More Control Over Infrastructure

If your organization wants to control the CI/CD environment directly, Jenkins provides that flexibility.

* * *

# ☁️ When Should You Choose AWS CodePipeline?

AWS CodePipeline can be a strong choice when:

### Your Organization is AWS-Centric

For example:

```text
AWS
   ↓
CodePipeline
   ↓
CodeBuild
   ↓
CodeDeploy
```

* * *

### You Don't Want to Maintain CI/CD Servers

With a managed service, AWS handles the underlying CodePipeline infrastructure.

* * *

### You Prefer Managed Services

Instead of managing:

```text
Server
 ↓
Jenkins
 ↓
Workers
```

you can focus on:

```text
Pipeline
 ↓
Build
 ↓
Delivery
```

* * *

### You Want AWS Integration

CodePipeline works naturally with other AWS services, particularly CodeBuild and CodeDeploy.

* * *

# 🆚 Simple Decision Table

| Requirement | Better Fit |
| --- | --- |
| Open-source CI/CD | Jenkins |
| Maximum flexibility | Jenkins |
| Multi-cloud environment | Jenkins |
| Custom CI/CD workflows | Jenkins |
| More infrastructure control | Jenkins |
| AWS managed orchestration | CodePipeline |
| Less CI/CD infrastructure management | CodePipeline |
| AWS-centric environment | CodePipeline |
| AWS-native CI/CD workflow | CodePipeline |
| Managed service model | CodePipeline |

This doesn't mean one tool is always better.

The correct choice depends on the organization's requirements.

* * *

# 🏗 Jenkins CI/CD Architecture

A simplified Jenkins workflow:

```text
                     Developer
                         ↓
                    Source Code
                         ↓
                      Jenkins
                         ↓
                  Jenkins Worker
                         ↓
                       Build
                         ↓
                        Test
                         ↓
                      Delivery
```

The key point:

> Jenkins orchestrates the workflow and the organization manages the required Jenkins infrastructure.

* * *

# ☁️ AWS CodePipeline Architecture

A simplified AWS-managed workflow:

```text

                         ↓
                 AWS CodePipeline
                    Orchestrator
                         ↓
                    AWS CodeBuild
                         ↓
                         CI
                         ↓
                   AWS CodeDeploy
                         ↓
                         CD
```

The key point:

> CodePipeline orchestrates the workflow while AWS manages the underlying CodePipeline service infrastructure.

# 🔥 Jenkins vs CodePipeline — The Core Difference

The entire comparison can be summarized as:

```text
                 JENKINS
                    ↓
              Open Source

# 🧠 Most Important Concept

Don't think:

> "Jenkins is better."

or:

> "CodePipeline is better."

Instead, think:

> **Which approach fits the organization's requirements?**

If the organization wants:

```text
Flexibility
+
Multi-Cloud
+
Control
+
Open Source
```

Jenkins can be a strong choice.

If the organization wants:

```text
Managed Service
+
AWS Integration
+
Less Infrastructure Management
+
AWS-Centric CI/CD
```

CodePipeline can be a strong choice.

* * *

# 🔗 How CodePipeline, CodeBuild and CodeDeploy Work Together

This is extremely important to understand.

Each service has a different responsibility.

```text
              AWS CodePipeline
                Orchestration
                     ↓
              AWS CodeBuild
                  CI
                     ↓
              AWS CodeDeploy
                  CD
```

### CodePipeline

Coordinates the workflow.

### CodeBuild

Performs CI-related build and test activities.

### CodeDeploy

Performs deployment-related activities.

Together:

```text
CodePipeline
     ↓
CodeBuild
     ↓
CodeDeploy
```

create an AWS-managed CI/CD workflow.

* * *

# 🧑‍💻 Jenkins Equivalent

Jenkins can perform or coordinate many of these activities itself or invoke other tools.

For example:

```text
Jenkins
   ↓
CI
   ↓
Build
   ↓
Test
   ↓
Invoke Deployment
```

The important difference is that Jenkins provides the automation platform, while CodePipeline coordinates AWS managed services.

* * *

# 🚀 Practical Learning Path

The next step after understanding CodePipeline is to implement CI/CD practically.

A simple learning progression is:

```text
GitHub
   ↓
AWS CodeBuild
   ↓
Simple CI
```

Then extend it to:

```text
GitHub
   ↓
AWS CodePipeline
   ↓
AWS CodeBuild
   ↓
CI/CD Workflow
```

Then:

```text
GitHub
   ↓
AWS CodePipeline
   ↓
AWS CodeBuild
   ↓
AWS CodeDeploy
   ↓
End-to-End CI/CD
```

This progression helps you understand the difference between:

```text
Simple CI
```

and:

```text
Complete CI/CD
```

# ❓ Interview Questions

## Q1. What is AWS CodePipeline?

**Answer:**

AWS CodePipeline is a managed AWS service that automates and orchestrates stages of the software release process.

* * *

## Q2. What is Jenkins?

**Answer:**

Jenkins is an open-source automation server commonly used to implement and orchestrate CI/CD pipelines.

* * *

## Q3. What is the main difference between Jenkins and AWS CodePipeline?

**Answer:**

Jenkins is an open-source tool that is typically self-managed, while AWS CodePipeline is a managed AWS service. Jenkins provides more flexibility and control, whereas CodePipeline reduces the infrastructure management burden.

* * *

## Q4. Why does Jenkins require infrastructure management?

**Answer:**

A self-managed Jenkins setup requires infrastructure to run the Jenkins controller and, depending on the workload, worker nodes or agents that execute pipeline jobs.

* * *

## Q5. What are Jenkins worker nodes?

**Answer:**

Jenkins worker nodes, also called agents, are execution environments used to run CI/CD jobs assigned by Jenkins.

* * *

## Q6. What is CI/CD orchestration?

**Answer:**

CI/CD orchestration means coordinating different stages of a software delivery workflow, such as source, build, testing, and delivery/deployment.

* * *

## Q7. Is AWS CodePipeline an orchestrator?

**Answer:**

Yes. CodePipeline acts as a managed orchestrator that coordinates pipeline stages and actions.

* * *

## Q8. What is the role of AWS CodeBuild in CodePipeline?

**Answer:**

CodeBuild can perform CI-related activities such as building and testing the application, while CodePipeline orchestrates when those activities should run.

* * *

## Q9. What is the role of AWS CodeDeploy in CodePipeline?

**Answer:**

CodeDeploy can perform deployment-related activities, while CodePipeline coordinates the deployment stage as part of the overall pipeline.

* * *

## Q10. Which is more flexible, Jenkins or CodePipeline?

**Answer:**

Jenkins is generally more flexible because it is open source, highly customizable, and can integrate with a broad range of platforms and tools.

* * *

## Q11. Which is better for a multi-cloud environment?

**Answer:**

Jenkins can be a strong choice for multi-cloud environments because it can orchestrate workflows across different cloud platforms and infrastructure.

* * *

## Q12. Why might AWS CodePipeline be preferred in an AWS-centric organization?

**Answer:**

Because CodePipeline is a managed AWS service and integrates naturally with AWS services such as CodeBuild and CodeDeploy, reducing the need to manage CI/CD infrastructure.

* * *

## Q13. Does open source mean Jenkins has no cost?

**Answer:**

No. Jenkins software is open source, but infrastructure, worker nodes, storage, maintenance, operations, and other resources can still create costs.

* * *

## Q14. What does pay-as-you-go mean for AWS CodePipeline?

**Answer:**

It means you use the managed AWS service and pay according to applicable AWS usage and pricing rather than purchasing and maintaining your own CI/CD orchestration infrastructure.

* * *

## Q15. Which one should an organization choose?

**Answer:**

It depends on requirements. Jenkins may be preferred for flexibility, customization, and multi-cloud environments. CodePipeline may be preferred for AWS-centric environments where a managed CI/CD orchestration service and reduced infrastructure management are priorities.

# 🏆 Final Conclusion

AWS CodePipeline and Jenkins both solve an important CI/CD problem: **orchestrating the software delivery workflow**.

But they follow two different approaches.

Jenkins represents the **open-source and self-managed model**.

```text
Jenkins
   ↓
Open Source
   ↓
Self Managed
   ↓
Worker Nodes
   ↓
More Control
   ↓
More Management
```

AWS CodePipeline represents the **managed AWS model**.

```text
CodePipeline
   ↓
AWS Managed
   ↓
CodeBuild
   ↓
CI
   ↓
CodeDeploy
   ↓
CD
```

The key trade-off is:

> **Jenkins gives you more flexibility and control, while AWS CodePipeline gives you a managed experience with less infrastructure management.**

Jenkins can be especially useful when an organization needs:

*   Open-source tooling
    
*   High flexibility
    
*   Custom CI/CD workflows
    
*   Multi-cloud support
    
*   More control over the environment
    

AWS CodePipeline can be especially useful when an organization needs:

*   AWS-native CI/CD
    
*   Managed orchestration
    
*   Less infrastructure management
    
*   Integration with AWS CodeBuild and CodeDeploy
    
*   A pay-as-you-go service model
    

Therefore, there is no universal winner.

The right choice depends on the organization's infrastructure, cloud strategy, engineering skills, flexibility requirements, and willingness to manage CI/CD infrastructure.

# 🚀 Final Takeaway

Remember this simple comparison:

```text
                 JENKINS
                    ↓
              Open Source
                    ↓
             Self Managed
                    ↓
            More Flexibility
                    ↓
           More Management
```

and:

```text
            AWS CODEPIPELINE
                    ↓
              AWS Managed
                    ↓
             CodeBuild → CI
                    ↓
            CodeDeploy → CD
                    ↓
        Less Infrastructure Management
```

**Jenkins = More control + More management**

**AWS CodePipeline = Managed experience + Less infrastructure management**

Understanding this difference is more important than simply memorizing the names of the tools.

In the next practical step, you can start with a simple **GitHub + AWS CodeBuild CI setup** and then extend it into a complete **AWS CI/CD pipeline using CodePipeline**.
