Cloud9 and instances

Can I have an EC2 instance for editing and testing and also a Lightsail instance for user interaction at the same time?

Yes, you can have both types of instances simultaneously within your AWS account. EC2 instances are suitable for development and testing, while Lightsail instances are convenient for hosting user-facing applications. They operate independently and can coexist within your AWS environment.

Can I run both Cloud9 IDE and user interaction services (like a website or API) on the same EC2 instance?

Technically, yes, it's possible to run both Cloud9 IDE and user interaction services on the same EC2 instance. However, it may not be the most efficient or recommended approach due to resource contention, security concerns, and scalability limitations. It's generally better to isolate development environments from production or user-facing environments for better manageability and security.

Running multiple services on a single EC2 instance is known as service consolidation or multitenancy.
