Terraform will recreate the instance as per the template
Terraform will detect that the instance is missing and recreate it based on the template
The new instance will have the same configuration as defined in the template
Any changes made to the instance outside of Terraform will be lost
The IP range for 500 IPs would typically be a /23 subnet.
For 500 IPs, you would need at least a /23 subnet.
A /23 subnet provides 512 IP addresses (2^9 = 512), with 510 usable IPs after subtracting network and broadcast addresses.
The IP range for a /23 subnet would be from x.x.x.0 to x.x.x.255.
Health checks after creating instances ensure the instances are functioning properly.
Instance status checks ensure the instance is reachable and responding to traffic.
System status checks ensure the underlying hardware is functioning properly.
Example: If an instance fails the system status check, it may indicate a problem with the underlying host hardware.
Microservices can be deployed using containerization tools like Docker and orchestration tools like Kubernetes.
Use containerization tools like Docker to package each microservice along with its dependencies into a container image.
