The feature that allows you to set the exact amount of memory and CPU is a custom machine type. Custom machine types in Google Cloud Compute Engine enable users to choose the specific combination of virtual CPUs (vCPUs) and memory. This flexibility allows for optimization based on the specific needs of applications, helping to ensure that resources are not over-allocated or under-utilized. By allowing users to define these parameters, custom machine types can lead to cost savings for users who only need a certain amount of resources rather than being locked into predefined instance types. Other services mentioned, such as Datastore and BigQuery, are designed primarily for specific types of workloads and do not provide the same level of resource customization. Datastore is a scalable NoSQL database service focused on managing structured data, while BigQuery is a data warehousing solution primarily for analytics and querying large datasets. `gsutil` is a command-line tool for interacting with Google Cloud Storage, which does not involve setting CPU and memory specifications at all.
