AWS Direct Connect provides a dedicated private network connection from on-premises data centers directly to the AWS Cloud, bypassing the public internet. This setup is ideal for reducing network costs, increasing bandwidth throughput, and providing a more consistent network experience compared to standard internet connections. Other services, such as Amazon VPC, relate to networking but do not establish a private network connection from on-premises to AWS.

AWS CloudHSM provides hardware-based key management to manage and protect encryption keys in the AWS Cloud.

AWS KMS is also relevant for key management but wasn't listed as an option in this question.

On-Demand Instances are most cost-effective for short-term, steady, and unpredictable workloads. Using them for a one-month testing period allows flexibility without a long-term commitment. For long-term workloads (like a year or more), Reserved Instances or Savings Plans would be more cost-effective. Spot Instances are better for interruptible, flexible workloads.
