Blue-Green Deployment Automation
A shell script-based blue-green deployment solution designed for seamless deployment with minimal downtime, leveraging AWS services and tools like Auto Scaling Groups (ASGs), Application Load Balancer (ALB), CloudWatch, and Ansible.
Ensures uninterrupted service during deployments
Quickly reverts to previous version if issues occur
Validates new changes in controlled environment
Gradually rolls out features to subset of users
SSL Certificate Monitoring
SSL certificate monitoring system with alerts via Slack, email, and Telegram. Ensures certificates don't expire unexpectedly, preventing service disruptions and security vulnerabilities.
Notifies via Slack, Email, and Telegram
Set different alert levels based on expiry
Simple setup for any infrastructure
Prevents certificate expiration issues
Integrated Email Tracking System
Centralized email system where all emails from different clients end up in one place. Users access it via web browser. System uses MySQL 5.0 database servers with replication.
All client emails in one place
Primary & secondary database servers
Email alerts for replication failures
Server beeps until issue is fixed
MySQL 5.0 with tuned my.cnf configuration for large file transfers. Exact snapshot replication from master to slave database. Automated alert system for replication failures.
I begin by thoroughly understanding your current infrastructure, pain points, and business goals. This helps me create a tailored strategy that aligns with your objectives.
Based on the assessment, I design a robust architecture that addresses your specific needs while ensuring scalability, security, and cost-effectiveness.
I implement the designed solutions using Infrastructure as Code, automation scripts, and best practices to ensure consistency and reliability.
Rigorous testing ensures that the implemented solutions work as expected and meet all requirements before going live.
I deploy the solutions using blue-green or canary deployment strategies to ensure zero downtime, and set up comprehensive monitoring for ongoing optimization.
I provide comprehensive documentation and conduct knowledge transfer sessions to ensure your team can effectively manage and extend the implemented solutions.
