Shared core with custom RAM

[Rocky Borrego]

Do the shared core e2-medium instances have one shared core and one dedicated core?

How do you create a Custom instance utilizing shared cores.  For example, I would like to have an e2-medium type machine (1 shared core and one dedicated core) but with more than 4 gigs of RAM.  Is this possible?

Shared-core machine types use context-switching to share a physical core between vCPUs for the purpose of multitasking. shared core e2-medium instances have one shared core.However, shared-core machine types offer bursting capabilities for  using additional physical CPU for short periods of time. Bursting happens automatically when your instance requires more physical CPU than originally allocated. During these spikes, your instance will opportunistically take advantage of available physical CPU in bursts. Note that bursts are not permanent and are only possible periodically. You can take a look at Shared-core machine types for details.

According to the aforementioned document memory limit for shared core e2-medium is 4 GB and I was unable to get any option to set custom memory  for this machine.Also I was unable to get option for creating Custom instance utilizing shared cores machine.More details on custom machine type .
