Done! gcutil is a command that is part of the SDK and can be used to interact with GCP. com/compute/docs/gcutil/tips. ccutil is considered legacy, and the replacement for it is gcloud. com/ compute/docs/gcloud-compute/. GCP Support Google provides bronze, silver, gold, and platinum support levels. Each level costs more than the previous one. Bronze-level support is free and provides support through the online help center. For an enterprise that needs 24/7 support, gold and platinum are the choices available.
For instance, in GCE you can control networks, firewalls, load balancers, and virtual machine configuration—none of which is feasible in GAE. If you need this level of control over your application, then use GCE and not GAE. com/compute/. Virtual Machines To create a virtual machine in GCE, you can use the Google Cloud SDK or the web interface. There are different configurations available for virtual machines. com/products/ compute-engine/. Pricing varies based on instance type. Listing 2-1 is an example of creating a virtual machine using the default settings.
