Google Compute Engine allows users to launch and manage virtual machine instances on Google's infrastructure. Key features include quotas on resources, creation of instances specifying zone, machine type, and boot options. The Google Cloud SDK and gcutil command can be used to automate tasks like creating instances. Startup scripts enable running custom commands when an instance boots. Backups can be done using disk snapshots, images, or by bundling a disk. VPN services can also be set up on Google Compute Engine using OpenVPN.

● Resource Quotas
○ Resource quotas describe the default quota for each
resource on a per-project basis. Each Google
Developers Console project is subject to default
quotas on the number of resources that a project
can have.

11. Google Compute Engine
Each project is subject to the following Google Compute
Engine global resource limits:
● Networks: 5
● Firewalls: 100
● Images: 100
● Snapshots: 5000
● Routes: 100
● Forwarding Rules: 50
● Target Pools: 50
● Health Checks: 50
● SSD Persistent Disk: 1TB

12. Google Compute Engine
Each region within a project is subject to the following
regional quotas:
● CPUs: 24
● Maximum total aggregate disk space: 5TB
● In-use IP addresses (both ephemeral and reserved): 23
● Reserved IP addresses: 7

13. Google Compute Engine
● You can change your quota if resource is not enough

○ Zone : Determine what computing resources are available and
where your data is stored and used.

● Create New Instance
○ Networking :
■ Network - tracffic rule (Firewall and Routes)
■ External IP (Ephemeral / Staic IP)
■ IP Forwarding (Disabled / Enabled)
○ Machine Type
○ Boot Source
■ image
■ disk
■ snapshot

18. Google Cloud SDK -
gcutil

19. Google Cloud SDK - gcutil
1. 下載Google Cloud SDK

20. Google Cloud SDK - gcutil
2. 安裝Google Cloud SDK，可參考安裝指南：
https://developers.google.com/cloud/sdk/#Quick_Start
3. 認證您的Cloud SDK :
$ gcloud auth login

21. Google Cloud SDK - gcutil
4. 上面指令執行完後，系統會打開瀏覽器進到下面的認證畫
面：

22. Google Cloud SDK - gcutil
5. 設定您的project
$ gcloud config set project <project>
6. 測試
$ gcutil

24. Google Cloud SDK - gcutil
● Create a Instance (using gcutil):
$gcutil addinstance instance-name
--zone=asia-east1-a
--machine_type=f1-micro
--image=centos-6-v20140619
--wait_until_running

25. Startup Script

26. Startup Script
● You can choose to specify a startup script
that will run when your instance boots up or
restarts.

27. Startup Script
● Example - Create an instance with a running
apache server

28. Startup Script
Step 1. Prepare you script :

29. Startup Script
Step 2. Create an instance and put your script
to instance’s metadata(use gcutil) :
$gcutil addinstance apache-server
--zone=asia-east1-a
--machine_type=f1-micro
--image=centos-6-v20140619 --wait_until_running
--tags=http-server
--metadata_from_file=startup-script:apache.sh

30. Startup Script
Step 3. Enter instance’s ip in your browser

31. Backup

32. Backup
● Disk - Use ‘dd’ command
(http://linux.vbird.org/linux_basic/0240tarcompress.php)
● Snapshot
● Image - Use gcimagebundle

33. Backup
● Snapshot

34. Backup
● Image - backup
○ Step 1. 在客製好的主機上做打包的動作
$ sudo gcimagebundle -d /dev/sda -o /tmp/ --log_file=/tmp/abc.log
○ Step 2. 傳送到google cloud storage
$ gsutil cp /tmp/XXX.image.tar.gz gs://arecord-customise-images

35. Backup
● Image - restore
○ 將image加到Google的image collection中，之後就可
以在web console中看到自己的image了
$ gcutil addimage test-image gs://arecord-customise-images/XXX.image.tar.gz
