4. For the past 15 years, Google has been building out the world’s fastest, most powerful, highest quality cloud infrastructure on the planet. Images by Connie Zhou Why Google Cloud Platform?
5. A Network that Spans the Globe
6. Innovating Software & Driving Technology Forward Spanner Dremel MapReduce Big Table Colossus 2012 2013 2002 2004 2006 2008 2010 GFS Compute Engine
7. Building Products that Scale Google Maps Gmail Google Drive YouTube
8. “[Google's] ability to build, organize, and operate a huge network of servers and fiber- optic cables with an efficiency and speed that rocks physics on its heels. This is what makes Google Google: its physical network, its thousands of fiber miles, and those many thousands of servers that, in aggregate, add up to the mother of all clouds.” - Wired Images by Connie Zhou

14. • IaaS: VMs, Network, Storage • Google DNA (speed, scale, reliable, secure) • Fast Provisioning, Consistent Performance • Enterprise Ready • 24x7 Support • 99.95% monthly SLA • ISO 27001, SSAE-16 SOC 1,2,3 • Accessible Through • Web @ https://cloud.google.com/console • gcutil command-line utility • REST API • Partners (Commercial and FOSS) Google Compute Engine
15. Launching 100 virtual machines
16. Block Storage Persistent Disks
17. Persistent Disk 10 TB • Data and root partitions • Billed only by capacity (GB/month) • Performance caps scale linearly with size • Volume striping is automatic • Differential snapshots • Create new PDs based on snapshots
18. PD Use-cases Root Stateful root volume User managed data volume Root RW Data RO Data Instant distribution of static content
19. Global Snapshot and Restore GCS vol1 vol2 vol3 vol1. t2 vol2. t2 vol3. t3 t1 t1 t1 t1 t1 t1 t1 t1 t1 t1 t1 t1 t1 t2 t2 t2 t2 t3 t3 t3 • Point in time snapshot to Google Cloud Storage (GCS) • Differential snapshots • GCS global replication! • Restore from snapshot anywhere in the world us-central1-a europe-west1-a
20. Virtual Machines
21. standard • For workloads with balanced CPU and memory highmem • For workloads with higher memory requirements highcpu • For workloads with higher CPU requirements Shared Core Instances • For inexpensive prototyping and staging workloads (g1-small, f1-micro) Machine Types Machine Type Virtual Cores Memory (GB) n1-standard-1 1 3.75 n1-standard-2 2 7.50 n1-standard-4 4 15.00 n1-standard-8 8 30.00 n1-standard-16 16 60.00 n1-highmem-2 2 13.00 n1-highmem-4 4 26.00 n1-highmem-8 8 52.00 n1-highmem-16 16 104.00 n1-highcpu-2 2 1.80 n1-highcpu-4 4 3.60 n1-highcpu-8 8 7.20 n1-highcpu-16 16 14.40
22. Images + Custom Kernel Support (debian backports works great for docker)
23. Sub-hour Billing 1 minute granularity 10 minute minimum
24. Enhanced Reliability us-central1-a scheduled maintenance event Live Migration • No downtime during scheduled datacenter maintenance events Automatic Restart • Instances automatically restarted if subjected to system events such as hardware failure
25. Networking
26. Images by Connie Zhou Networking • Google's Network • Projects are isolated private networks • TCP, UDP, ICMP only • Multiple private network groups and firewalls • Tags and address ranges • Addresses • public: static or ephemeral • private: ephemeral with DNS • Routes, gateways, VPNs, and IP Forwarding
27. Region: us-central1 Target Pool (tp-a) Load-balancer • Region based • Session affinity • Hashed on src ip:port and dst ip:port • Consists of: • Target pool: collection of instances • Forwarding rules: protocol:port, pool • HTTP health check: optional us-central1-b us-central1-a www0 www1 www2 www3 Forwarding Rules tcp:443 ➔ tp-a tcp:80 ➔ tp-a Internet http://googlecloudplatform.blogspot.com/2013/11/compute-engine-load-balancing-hits-1-million-requests-per-second.html
28. ...and
29. Noteworthy • Metadata • Startup scripts • SSH Keys • Tags (instance/network) • OAuth2 and Scopes • Access other Google Cloud Platform services • Ecosystem is growing • Partners: RightScale, Scalr, New Relic, MongoLab, MapR, and many more... • Open Source: Salt, Chef, Puppet, Ansible, Vagrant, Docker, CoreOS, fog, libcloud

31. Start to finish 1. Use the Developers Console to create the salt master (metadata: saltdemo=yup) salt This is a Compute Engine instance named "salt"
32. Start to finish 1. Use the Developers Console to create the salt-master (metadata: saltdemo=yup) 2. Use salt-cloud to create 4 instances (2 per zone), install apache us-central1-a minion1 minion3 us-central1-b minion2 minion4 salt # salt-cloud -P -m /etc/salt/demo.map # salt 'minion*' state.highstate Google Public API
33. Start to finish 1. Use the Developers Console to create the salt-master (metadata: saltdemo=yup) 2. Use salt-cloud to create 4 instances (2 per zone) 3.
