Machine Families

Different Machine Families for Different Workloads:

General Purpose (E2, N2, N2D, N1) : Best price-performance ratio

Web and application servers, Small-medium databases, Dev environments

Memory Optimized (M2, M1): Ultra high memory workloads

Large in-memory databases and In-memory analytics

Compute Optimized (C2): Compute intensive workloads

Gaming applications

Machine Images

• Public images.

• Customer images.

IP Addresses

External IP Addresses

• External IP addresses are lost when a machine is stopped.

Static IP Addresses - Remember

• Static IP can be switched to another VM instance in same project. Use External IP addresses in the menu.

• Static IP remains attached even if you stop the instance. You have to manually detach it.

• Remember : You are billed for an Static IP when you are NOT using it! (You pay more if you are not using it!).A

Bootstrapping - Startup Script

• Available in the machine configuration.

Instance Templates

• Define machine type, image, labels, Startup script and other properties.

• Used to create VM instances and managed instance groups.

• (Optional) Image family can be specified (example - debian-9): Latest non-deprecated version of the family is used.

Custom Image

• Installing OS patches and software at launch of VM instances increases boot up time. Prefer customer images.

• Image can be stored in Cloud Storage.

• Deprecate old images (& specify replacement image).

Other

• If you want dedicated hardware for your compliance, licensing, and management needs - use Sole-tenant nodes.

• To manage 1,000’s nodes use VM Manager.
