But, do you know why both of these exists? What happens underneath? And what are the best practices when using one or the other?

In this article, I will discuss the usage of require and import and answer some of these common questions.

AWS EC2 is one of the most used could services around the world. However, most new developers aren’t aware of the cost of maintaining an EC2 instance and end up paying unnecessarily.

So, in this article, I will compare all the EC2 instance purchasing options and discuss how to use spot instances to reduce the cost even for your production environments.

AWS EC2 Instances Purchasing Options

Although many developers are only aware of On-Demand EC2 instances, AWS provides 5 purchasing options for EC2 instances. Which are,

1. On-Demand Instances.
2. Reserved Instances.
3. Spot Instances.
4. Dedicated Instances.
5. Dedicated Hosts.

These options have their features and suitabilities. SO, before…

So, in this article, I will discuss how we can use AWS RDS Proxy, a fully managed, highly available database proxy provided by AWS to manage AWS relational databases.

Why Do We Need RDS Proxy?

Before getting into details about RDS Proxy, let’s see why we need such services.
