Application Deployment Process: Start Date : 15 Sep 2023

End Date : 20Sep 2023

Day One :

install Proxmox on an OVH server with a public IP and then install and configure Ubuntu as a virtual machine, you can follow these steps:

Provision OVH Server: Access your OVH account and provision a server with the desired specifications, including a public IP address.
Connect to the Server: Once the server is provisioned, you can connect to it via SSH using a terminal application like Terminal (Mac/Linux). Use the server's public IP address and the SSH credentials provided by OVH.
Install Proxmox VE: Proxmox VE is a server virtualization platform that will allow you to create and manage virtual machines. Follow the official Proxmox VE installation guide specific to your server's operating system. Typically, it involves running a script provided by Proxmox to install the necessary packages.
Access Proxmox Web Interface: Once Proxmox VE is installed, access its web interface by opening a web browser and entering the server's IP address followed by the default port 8006. For example, https://<server_ip>:8006. Accept any security warnings and log in using the default username root and the password set during the Proxmox installation.
Configure Network: In the Proxmox web interface, navigate to "Datacenter" -> "Network" -> "VM Network" and configure the network settings for your virtual machines. Ensure the public IP address assigned to your OVH server is properly configured.
Create Virtual Machine (VM): In the Proxmox web interface, click on "Create VM" to create a new virtual machine. Follow the wizard to specify the VM settings, such as the amount of RAM, CPU cores, disk space, and networking. Choose Ubuntu as the guest OS template.
Install Ubuntu on the VM: After creating the VM, select it in the Proxmox interface and click on "Console" to access the virtual machine's console. Start the VM and mount the Ubuntu ISO image to perform the installation. Follow the Ubuntu installation process, configuring options like language, partitioning, and user credentials.
Configure Ubuntu: Once Ubuntu is installed, log in to the virtual machine and perform any necessary configurations. Update the system packages using sudo apt update and sudo apt upgrade. Install additional software, set up firewall rules, configure network interfaces, etc., as per your requirements.
Access Ubuntu VM: To access the Ubuntu VM from your local machine, you can use SSH or remote desktop tools like VNC. Ensure you have network connectivity between your local machine and the OVH server.

Day TWO :

Containerize application: Package your application and its dependencies into a container image. Kubernetes uses containers to run and manage applications. You can use tools like Docker to create container images.
Create Kubernetes manifests: Kubernetes uses YAML or JSON files called manifests to define the desired state of your application. Manifests describe the resources that Kubernetes should create and manage, such as pods, services, deployments, and ingress rules. You need to create these manifests to define your application's structure, dependencies, and configurations.
Define a Deployment: A Deployment is a Kubernetes resource that manages the lifecycle of your application. It ensures that the desired number of instances (replicas) of your application are running and handles updates and rollbacks. You define a Deployment in your manifest file, specifying details like the container image, replicas, labels, and environment variables.
Apply the manifests: Use the kubectl apply command to apply your Kubernetes manifests to the cluster. This command creates or updates the specified resources based on the desired state defined in the manifests.
Verify the deployment: After applying the manifests, you can use kubectl commands to verify the status of your deployment. For example, kubectl get pods shows the running pods, kubectl get deployments shows the status of the deployments, and kubectl logs <pod-name> retrieves the logs of a specific pod.
Expose the application: To make your application accessible from outside the cluster, you'll need to expose it using a Service. A Service is a Kubernetes resource that provides a stable network endpoint to access your application. There are different types of Services, such as ClusterIP, NodePort, and LoadBalancer. You define and create a Service in your manifest file.
Scale and update the deployment: Kubernetes allows you to scale your application horizontally by adjusting the number of replicas in your Deployment. You can use the kubectl scale command to scale your application. To update your application, you modify the Deployment's manifest file with the new version or configuration and apply the changes using kubectl apply again.
Monitor and manage: Kubernetes provides various tools and approaches for monitoring and managing your application. You can use kubectl commands, Kubernetes Dashboard, or third-party monitoring tools to monitor the health, resource usage, and logs of your application.

Day Three :

build a setup that includes Amazon S3 for Laravel media storage, Amazon CloudFront for content delivery, and Amazon SES for email integration in a Laravel application, you can follow these steps:

Set up an AWS Account: If you don't already have one, create an AWS account at https://aws.amazon.com and ensure you have the necessary permissions to create and manage services like S3, CloudFront, and SES.
Configure Laravel: Install and configure Laravel for your application. This involves setting up the database connection, configuring the mail driver (to use SES later), and any other necessary Laravel configurations.
Set up Amazon S3: Create an S3 bucket in the AWS Management Console. This bucket will store your media files. Ensure you have the appropriate permissions to access the bucket. You may need to create an IAM user and attach the necessary policies.
Install and Configure Laravel S3 Driver: Install the league/flysystem-aws-s3-v3 package through Composer to enable Laravel's S3 driver. Configure the S3 driver in Laravel's filesystems.php configuration file, specifying the S3 bucket and credentials.
Upload and Retrieve Media: In your Laravel application, use the storage facade to upload and retrieve media files. For example, you can use Storage::put() to upload files to S3 and Storage::url() to generate URLs for accessing the files.
Set up Amazon CloudFront: Create a CloudFront distribution in the AWS Management Console. Configure CloudFront to use your S3 bucket as the origin and specify the desired settings, such as caching, SSL, and custom domain names. CloudFront acts as a content delivery network (CDN) to cache and deliver your media files globally.
Integrate CloudFront URLs in Laravel: Replace the direct S3 URLs in your Laravel application with the CloudFront URLs generated for your media files. This ensures that files are served through CloudFront for faster and more efficient delivery.
Set up Amazon SES: In the AWS Management Console, create an SES (Simple Email Service) configuration, verify your domain or email addresses, and configure the necessary email settings, such as DKIM and SPF records.
Configure Laravel Mail: Update Laravel's mail driver configuration to use SES. Modify the mail.php configuration file and specify the SES SMTP credentials and region.
Send Emails: Use Laravel's built-in mail functionality (Mail facade) to send emails from your application. Laravel will use SES as the underlying mail transport.
Test and Verify: Test the media upload/download functionality and email sending from your Laravel application to ensure everything is working as expected. Monitor logs and error messages to identify and resolve any issues.

Day Four :

Day Five :

Build a data protection process for a MySQL database and Laravel media files stored in an S3 bucket with a lifecycle policy without encryption, you can follow these steps:

Backup MySQL Database: Implement a regular backup strategy for your MySQL database to protect against data loss. Use tools like mysqldump or database backup services to create automated backups at scheduled intervals. Store the backups in a secure location, such as a separate server or cloud storage.
Store Laravel Media Files in S3: Configure your Laravel application to store media files in an S3 bucket. Set up the necessary credentials and access policies to ensure secure access to the bucket. This allows you to offload the storage of media files to a scalable and durable object storage service.
Enable Server-Side Logging: Enable server-side logging for the S3 bucket to capture access logs. This will help you monitor and track any unauthorized access attempts or suspicious activities related to your media files.
Configure Lifecycle Policy: Define a lifecycle policy for your S3 bucket to manage the lifecycle of the media files. The lifecycle policy can specify rules to transition or expire objects based on criteria such as age, object size, or specific prefixes. For example, you can set rules to automatically move files to Glacier storage after a certain period or delete files that have reached their retention period.
Enable Versioning: Enable versioning for the S3 bucket to preserve multiple versions of the media files. This provides an additional layer of protection by allowing you to restore previous versions of files in case of accidental deletion or corruption.
Implement Access Controls: Apply appropriate access controls to your MySQL database and the S3 bucket to restrict unauthorized access..
Monitor and Test: Regularly monitor the backup process, database integrity, and S3 storage to ensure everything is functioning correctly. Perform periodic tests to restore data from backups and validate the integrity of the restored data.
Disaster Recovery Plan: Develop a comprehensive disaster recovery plan that includes steps to restore the MySQL database and media files from backups in case of data loss or system failure. Document the procedures and regularly review and test the plan to ensure its effectiveness.
Regularly Update and Patch: Keep your MySQL database, Laravel application, and server infrastructure up to date with the latest security patches and updates. Regularly review and apply Laravel framework updates and security best practices to protect against vulnerabilities.
