You are running an online gaming application hosted on a VM.Standard2.1 instance shape in Oracle Cloud Infrastructure.
As the game becomes popular, you identify network throughput as a bottleneck on your instance when uploading user data.
Though you want to resolve the issue, you want to observe the demand for a week before adding new application instances.
Which action is the most efficient way to resolve this issue?

The most efficient way to resolve the network throughput bottleneck on the VM.Standard2.1 instance in Oracle Cloud Infrastructure is to add a secondary virtual network interface card (VNIC).
Explanation: A virtual network interface card (VNIC) is a virtualized network interface that enables a VM to communicate with other instances, services, and resources on the same VCN (Virtual Cloud Network) or across VCNs. By adding a secondary VNIC to the instance, you can double the network throughput capacity of the instance. This is because the instance now has two network interfaces that can process network traffic independently.
Changing the shape of the instance to a higher network bandwidth instance is another possible solution, but it is not the most efficient one for the following reasons:
It requires downtime: Changing the instance shape requires stopping the instance, changing its shape, and starting it again. This will result in downtime that may affect the availability of the game application.
It is a permanent change: If you are not sure about the long-term demand for the game application, changing the instance shape permanently may not be the best solution.
Deleting the instance and spinning up a new instance with a higher network bandwidth may seem like a solution, but it is not the most efficient one because it requires additional steps to preserve the boot volume and reconfigure the instance. This solution is also prone to the same drawbacks as changing the instance shape, such as downtime and permanent changes.
Changing the performance tier of attached block volume to High Performance is not relevant to the network throughput bottleneck issue. It can improve the storage performance of the instance, but it will not affect the network throughput capacity.
In conclusion, adding a secondary VNIC to the VM.Standard2.1 instance is the most efficient way to resolve the network throughput bottleneck without causing downtime or making permanent changes to the instance.
