Deploying Applications on OCI: A Detailed Guide
Oracle Cloud Infrastructure (OCI) offers a powerful platform to deploy, manage, and scale your applications. In this guide, we’ll walk you through the process of launching virtual machines, configuring load balancers, and deploying web apps on OCI. Whether you’re new to OCI or looking to expand your cloud expertise, this comprehensive guide provides step‑by‑step details to help you get started.
1. Introduction
Deploying applications on OCI involves several key steps:
- Launching Virtual Machines (VMs): Provision compute instances tailored to your workload.
- Configuring Load Balancers: Distribute incoming traffic efficiently to ensure high availability.
- Deploying Web Apps: Set up your web applications on OCI to serve your users reliably.
By mastering these steps, you can build a scalable and resilient cloud infrastructure that meets your business needs.
2. Launching Virtual Machines on OCI
A. Create a Compute Instance
- Log in to OCI Console:
Visit the OCI Console and sign in with your credentials. - Navigate to Compute:
In the left-hand menu, select Compute > Instances. - Launch a New Instance:
- Click Create Instance.
- Name Your Instance: Choose a unique name.
- Select an Image: Choose from a variety of operating system images (e.g., Oracle Linux, Ubuntu, Windows).
- Choose a Shape: Select a shape (CPU, memory configuration) that meets your application requirements.
- Configure Networking: Assign the instance to a Virtual Cloud Network (VCN) and subnet. Configure public IP if external access is needed.
- Add SSH Keys (for Linux/Unix): Upload your public SSH key for secure access.
- Review and Launch:
Review your settings and click Create. Your instance will be provisioned within a few minutes.

3. Configuring Load Balancers
A. Set Up a Load Balancer
Load balancers help distribute traffic across multiple instances, ensuring high availability and responsiveness.
- Navigate to Load Balancers:
In the OCI Console, go to Networking > Load Balancers. - Create a New Load Balancer:
- Click Create Load Balancer.
- Name Your Load Balancer: Provide a descriptive name.
- Select a Shape: Choose the appropriate size based on expected traffic.
- Configure Listeners:
- Add a listener for HTTP (port 80) or HTTPS (port 443).
- Configure SSL settings if using HTTPS by uploading your certificate and key.
- Backend Set Configuration:
- Create a backend set by adding the IP addresses of your compute instances.
- Set health check parameters (protocol, port, URL path) to monitor instance health.
- Review and Create:
After reviewing your settings, click Create to provision the load balancer.
4. Deploying Web Applications
A. Deploying to Your Compute Instance
Once your VM is running, you can deploy your web applications using various methods, depending on your tech stack.
- Manual Deployment:
- Access Your Instance:
SSH into your Linux instance or use RDP for Windows. - Install Web Server Software:
For example, install Apache HTTP Server or Nginx:sudo apt update && sudo apt install apache2 - Deploy Your Application Files:
Place your HTML, CSS, JavaScript, or application code in the web server’s document root (e.g.,/var/www/htmlfor Apache). - Restart the Web Server:
sudo systemctl restart apache2
- Access Your Instance:
- Automated Deployment:
- Use CI/CD pipelines (e.g., Jenkins, GitLab CI/CD) to automate the deployment process.
- Configure your pipeline to connect to your OCI instance, push updates, and restart services as needed.
B. Integrating with a Load Balancer
- DNS Configuration:
Update your DNS records to point your domain to the load balancer’s public IP address. - Test the Setup:
Navigate to your domain to ensure that the load balancer correctly routes traffic to your compute instances.
5. Best Practices
- Scalability:
Use auto-scaling policies to automatically add or remove instances based on traffic. - Security:
Ensure your instances and load balancers are secured with firewalls, proper IAM roles, and SSL/TLS. - Monitoring:
Leverage OCI’s built‑in monitoring tools to track instance performance, load balancer health, and application metrics. - Backup and Recovery:
Regularly back up your application data and configuration files. Test your recovery procedures to minimize downtime.
