About Me

Designing resilient systems on AWS cloud infrastructure

I’m Rajesh Kumar Tharu, an Information Technology graduate with a strong focus in cloud computing, AWS infrastructure, solutions architecture, Linux systems, and backend engineering.

My professional focus is architecting secure, scalable, highly available, and cost-conscious AWS cloud solutions following the Well-Architected Framework.

I have a software development background with experience in Python and Django, which helps me understand how applications interact with databases, APIs, infrastructure, and cloud environments.

I hold the AWS Certified Solutions Architect – Associate certification and strengthen my practical skills through hands-on architecture labs, Linux systems, networking, databases, and cloud deployment.

Cloud Architecture Lab

Highly Available AWS Web Application Architecture

Multi-AZ Resilient Tiered Infrastructure on AWS

Designed a multi-AZ AWS architecture focused on availability, scalability, security, and cost optimization.

Problem:

Single points of failure and unmanaged traffic spikes risking application downtime, latency, and unpredictable infrastructure costs.

Solution:

Architected a Multi-AZ VPC deployment isolating public entry points from private compute and database tiers, utilizing Application Load Balancers and dynamic Auto Scaling.

Architecture Flow:
Internet Route 53 Application Load Balancer EC2 Auto Scaling Amazon RDS
Supporting Services:
VPC Public/Private Subnets Security Groups IAM S3 CloudWatch
Key Learning:

Strategically balancing high availability with cost optimization via synchronous Multi-AZ database standby instances and metric-driven Auto Scaling policies.
