This is a realistic three tier style deploy kept fully private. You stand up a VPC with public and private subnets, run EC2 instances in the private subnets behind an Application Load Balancer with health checks, lock traffic down with security groups, and expose the app through an internal Route 53 record instead of the public internet. The ALB sits where it can reach the instances, the security groups only let the ALB talk to the app port, and the Route 53 record points at the load balancer. Where people slip is security group chaining and putting the instances somewhere the ALB cannot actually reach. VPC layout, ALB health checks, security groups, and internal DNS together make a strong AWS architecture interview question because they force you to connect networking, compute, and routing into one working system.

We will merge customer records from two sources. Snowflake is a cloud-based data warehouse that uses SQL. We are given two tables, customers from West and customers from East. Both of the tables contain the same columns and store information about the customers, such as full name, age, ID, and subscription plan type. Our job is simply to combine these two tables into one single result, even if they contain duplicate rows. FROM clause in Snowflake is a little bit different from SQL. It uses a dynamic reference with the ref function. Inside of the double curly braces, we put the ref function with the name of our table. In SQL and Snowflake, UNION operator is a set operation used to combine the result sets of two or more SELECT statements into a single unified output. If we use UNION separately, it would remove all duplicate rows. So using UNION ALL simply means that we want to keep all rows, even if they are repeated.
