Magento Upgrade Service for an Online Store on AWS

Our Customer

Gorgany is a huge retail, wholesale & distribution company of outdoor equipment in Ukraine. The company specializes in the wholesale trade of goods for tourism, mountaineering, skiing, and active recreation.

The Obstacles They Faced

The client needed to transition from Magento 2.3 to 2.4 with minimal downtime, and avoiding any potential technical difficulties during the migration. As interruption could directly lead to decreased purchases, making a seamless upgrade was crucial to ensure operational continuity and prevent negative commercial impacts.

How We Helped

We realized a Magento upgrade (from Magento 2.3 to Magento 2.4) for their web stores by leveraging AWS infrastructure and best DevOps practices. We executed the transition with minimal interruptions, proactively mitigating all anticipated concerns that could arise during the implementation.

Pre-Upgrade Preparation

IT Environment Setup

Infrastructure as Code (IaC) Implementation
We utilized Terraform to provision and manage AWS resources such as ECS, RDS, CloudFront, Redis, MQ, and S3. This method maintained consistent and repeatable infrastructure deployment, enhancing reliability and scalability.

Staging Environment Establishment
To mirror the production environment, we created a staging environment using IaC scripts. This setup included configuring ECS, RDS, CloudFront, Redis, and MQ to replicate the production infrastructure, ensuring accurate testing and seamless transitions.

Configuration Management
Here we employed Docker to build images with the necessary dependencies, PHP versions, and configurations required for Magento 2.4. This streamlined the deployment process and maintained consistency across different environments.

Backup and Recovery

A robust fallback strategy was implemented to quickly revert to the previous version of Magento in case of critical issues. This included restoring from backups and redirecting traffic back to the old environment, preventing disruptions.

Compatibility Check

The thorough review of all third-party extensions and custom themes were made to establish compatibility with 2.4 version. Our team collaborated with vendors to obtain updates or patches for any incompatible extensions, testing these in the staging environment.

Testing and Validation

Continuous Integration/Continuous Deployment

CI/CD Pipeline
We set up a CI/CD pipeline using Jenkins to automate the build, testing, and deployment processes. The pipeline included steps for code validation, automated testing, and deployment to the staging environment, resulting in a streamlined and efficient workflow.

Automated Testing
We integrated unit tests, integration tests, and end-to-end tests into the CI/CD pipeline. Tools such as PHPUnit for unit testing, JMeter for load testing, and Selenium for end-to-end testing were used to conduct comprehensive reliability testing.

Performance Testing

Load Testing
We conducted load testing using Apache JMeter to simulate high traffic and identify performance bottlenecks. This allowed us to optimize the system for peak performance under various conditions.

Performance Monitoring
We utilized AWS CloudWatch and Prometheus to monitor application performance and metrics continuously. This proactive approach ensured that any performance issues could be quickly identified and addressed.

Upgrade Execution

Maintenance Window

Scheduled Upgrade
We scheduled the upgrade during off-peak hours to minimize impact on users. The maintenance window was communicated to users in advance, which led to transparency and minimal disruption.

Blue-Green Deployment
To shorten downtime, we implemented a blue-green deployment strategy. This involved deploying the new version of Magento to a parallel environment and switching traffic to the new environment once testing was complete, ensuring a flawless transition.

Database Migration

We used scripts to migrate data from MySQL to MariaDB, ensuring data integrity and minimal technical outage. This meticulous process entailed a seamless transfer of all necessary data.

Code Deployment

Deployment Automation
We automated the deployment process using Jenkins for consistent and repeatable deployments. This automation reduced the risk of human error and enhanced the efficiency of the upgrade process.

Cache Management
We utilized Redis for session and cache storage. With the optimal performance and a seamless user experience in mind, we implemented automated cache clearing and reindexing as part of the deployment process.

Post-Upgrade Validation

Functional Testing

Any issues identified during UAT (User Acceptance Testing) were promptly addressed and fixes were redeployed using the CI/CD pipeline. This step is responsible for all functionalities working seamlessly post-upgrade.

Performance Observability

Real-Time Monitoring
AWS CloudWatch and Prometheus were utilized for real-time performance monitoring. Alerts were set up to detect any anomalies or performance degradation so as to immediately address potential issues.

Optimization
Based on real-time metrics and user feedback, continuous refinement was performed. This included tuning database queries and adjusting server configurations to enhance performance and user experience.

Go Live

DNS Update

The DNS was switched to point to the new Magento 2.4 environment using AWS Route 53, ensuring a seamless transition from the old to new environment with minimal disruption.

User Notifications

Users were informed about the upgrade, new features, and any expected downtime through email notifications and website banners. This proactive communication helped manage expectations and maintain user trust.

Continuous Monitoring

The environment continued to be monitored using AWS CloudWatch and AWS Trusted Advisor. This ongoing vigilance was necessary for sustained performance and security, more specifically, by promptly addressing any issues that arose.

Infrastructure Diagram

By leveraging AWS infrastructure and best DevOps practices, the upgrade of the clients’ platforms from Magento (Adobe Commerce) version 2.3 to 2.4 was successfully executed, resulting in enhanced performance, security, and scalability of the solutions while ensuring a seamless experience for its users.

Business Continuity

The project achieved a seamless upgrade with minimal downtime. This aguaranteed no data loss and provided an uninterrupted user experience during the transition, ultimately preventing any financial impact for the client.

Improved Performance

Following the upgrade, a significant 25% faster page load time was observed. This enhancement contributed to a faster and more responsive platform, improving overall user satisfaction.

User Satisfaction

Positive feedback from users highlighted their satisfaction with the seamless transition and improved performance. The smooth Magento upgrade process reinforced user trust and confidence in the platform.

Enhanced Security

In the 2.4 version of the Magento, over 30 security issues were addressed to protect against remote code execution (RCE) and cross-site scripting (XSS). Therefore the upgrade fortified the client’s solutions against potential threats and ensured overall protection for user data.

Automated Scalability

By leveraging AWS auto-scaling features, the platform can now efficiently handle increased traffic. This scalability ensures that the system can adapt to varying loads without compromising performance.

Operational Efficiency

The use of CI/CD pipelines and configuration management tools has established a repeatable process for future upgrades. This ensures that subsequent updates can be performed efficiently and with minimal risk, maintaining the platform’s reliability.
