NodeJS with the Google Cloud

Johann du Toit and Hiren Patel, GDE's for Cloud. Demo some features of the Google Cloud and try to show some demo's of running NodeJS on Compute with Replica Clusters and Templates

7. So getting started by Hiren
9. • Run virtual machines in the cloud (not just any cloud though) • Choose a machine type to suit your application needs • variety of OS images to choose from, or a custom one • live migration and disruption free maintenance • persistent storage, encrypted before stored to media • API access • competitive pricing (following Moore's law)
10. • Create/select a project at cloud.google.com/console • Enable billing for the project • Go to APIs, enable google compute engine • Create or note your project id (required later)
11. ➔ curl https://sdk.cloud.google.com | bash • tab completion for command arguments!
12. • gcloud - manage google cloud platform resources • gcutil - cli tool for GCE ➔ gcloud auth login ➔ gcutil getproject --project=<project-id> -- cache_flag_values
13. ➔ gcutil listmachinetypes • standard, high memory, high cpu, shared core ➔ gcutil --project=<project-id> addinstance <instance- name> --machine_type=n1-standard-1 • Instances run in regions/zones ➔ gcutil listregions ➔ gcutil listzones
14. • images - OS/root filesystem • public (google, vendors, etc), or project private ➔ gcutil listimages • can be created from root persistent disks (gcimagebundle, gcutil addimage) • images can be created from scratch - advanced usage (see the docs)
15. • Disks - persistent, network based storage • standard or ssd disks • lifecycle separate to that of instances ➔ gcutil listdisks/getdisks ➔ gcutil adddisk/attachdisk/detachdisk/deletedisk ➔ gcutil push/pull • IOPS performance increases with disk size • throughput grows to max of VM limit • under the hood, data is striped across many disks • modeled for predictable performance
16. ➔ gcutil addinstance my-first-instance --machine_type=f1- micro --image=debian-7 --zone=us-central1-a -- wait_until_running --auto_delete_boot_disk ➔ gcutil listinstances ➔ gcutil getinstance my-first-instance ➔ gcutil push my-first-instance testfile /home/hiren/ ➔ gcutil ssh my-first-instance ➔ gcutil listdisks ➔ gcutil deleteinstance my-first-instance
17. • Default network, allow ssh, allow internal • Max 2 IPs, internal, and optional external • Traffic through external IP is billed • External IPs are static or ephemeral ➔ gcutil listaddresses • up to 5 networks, IPv4 • max egress cap of 2Gbits/second per cpu core ➔ gcutil listfirewalls/addfirewall/deletefirewall ➔ gcutil addfirewall http2 --description="Incoming http allowed." --allowed="tcp:http"
18. • https://cloud.google.com/products/calculator/ • Instances billed for 10 mins, then by the minute • Sustained use discounts • Persistent disks billed by GB, not IOPS. Bill does not vary on usage fluctuations of a disk • Details at https://developers.google. com/compute/pricing
19. Node.JS & Compute Give us 5 min to swap around the command centre ... by Johann
20. Load-Balancers with health checks
21. Balance HTTP traffic and normal network traffic
25. Replica Pools quickly create pools of servers
26. AutoScaler scale up or down when criteria you specify is met
27. Deployment Manager deploy your entire infrastructure
28. Demos ?
29. Demo #1 Simple NodeJS Web Service on Compute
31. Demo #2 Using Compute to umm .. to compute
32. Google cloud platform credits: “DR-IN”
33. Q&A Brave Question Soldiers get Google swag
34. Thanks and good night !
