Isolation Levels in Databases Explained (Read Uncommitted to Serializable)

Описание: In this video, we do a deep dive into Isolation, one of the core ACID properties, by exploring all major database isolation levels.

You’ll clearly understand:
Read Uncommitted — what it allows and why it’s rarely used
Read Committed — how most databases behave by default
Repeatable Read — preventing non-repeatable reads
Serializable — the strongest isolation and its trade-offs

📘 Hands-on AWS ECS Deployment

This system design series focuses on architecture and concepts.
If you want to actually DEPLOY Spring Boot microservices securely on AWS ECS, I’ve created a complete, hands-on Udemy course.

What you’ll learn (end-to-end, production focused):
• Dockerize multiple Spring Boot microservices
• Push images to Amazon ECR and manage versions
• Design secure AWS networking (VPC, private subnets, NAT, security groups)
• Create ECS clusters, task definitions, and services
• Configure Application Load Balancer and target groups
• Use AWS Parameter Store for secure configuration management
• Integrate API Gateway with ECS using VPC Links
• Enable service discovery and Service Connect for inter-service communication
• Configure logging and monitoring using CloudWatch
• Implement ECS service auto-scaling with alarms
• Build a CI/CD pipeline using AWS CodeBuild and pipelines for automated deployments
