Cloud Platform overview 

Why Google Cloud Platform? Tight integration with Google Apps Rich variety of cutting edge PaaS & IaaS services Build on the same infrastructure that powers Google! Hands-off operation and monitoring including auto-scaling 

Compute Compute Engine App Engine 

Storage Cloud Datastore Cloud Storage Cloud SQL 

Services Cloud Endpoints BigQuery 

Cloud Console Cloud SDK REST APIs 

IaaS PaaS SaaS Gmail, Google Drive and Google Calendar App Engine Compute Engine Cloud Storage 

The story so far 

App Engine PaaS Java, Python, PHP & Go Free quota Auto scaling Massively scalable Traffic splitting 

Cloud Storage IaaS Multi-petabyte Globally replicated Tightly integrated into GCP Flexible security model

App Engine & Datastore Middleware Web traffic Student records Assessments (read only) 

Cloud Storage Middleware Web traffic Document Store Documents / Static Web Content 

Lessons learnt Billing / support is really important to address early on User authentication is super-simple for Google Apps domains Web apps require a small amount of ongoing development The platform is growing very rapidly In practise App Engine is super-reliable 

Support Choice of Silver, Gold or Platinum Can then apply for Premier status including offline billing Architecture Support Google Enterprise Support Center Optional 24x7 and Phone support

Where to next? 

Compute Engine IaaS Compute, Storage & Network Sub-hour billing Hugely scalable Consistent performance Linux (& Windows preview) 

Usage outline Micro (shared CPU) instances ideal for mass education use One virtual machine per student One hour lab usage for 30 students and instances less than $0.50 One year hosting approx $90.00 per (micro) instance Use App Engine and APIs to orchestrate 

App Engine Compute Engine Orchestration (or use Ansible, Chef, Puppet or Salt) Virtual machine running Node.js, PHP, Python ...etc. Student / User 1 1 1…* 

Lightweight containers Multiple containers per instance Transfer workloads between local infrastructure and cloud! 

“Kubernetes builds on top of Docker to construct a clustered container scheduling service. Kubernetes enables users to ask a cluster to run a set of containers. The system will automatically pick worker nodes to run those containers on, which we think of more as "scheduling" than "orchestration". Kubernetes also provides ways for containers to find and communicate with each other and ways to manage both tightly coupled and loosely coupled sets of cooperating containers.” Source: https://github.com/GoogleCloudPlatform/kubernetes/blob/master/DESIGN.md Kubernetes

Caveats Port 25 blocked for outgoing mail (use Sendgrid or similar) TCP, UDP or ICMP traffic only By default only port 22 (SSH) is open By default SSH password authentication is disabled Check for default quota limits in all services 

Summary We use Cloud Storage to expose highly-reliable, user-facing static web content Use App Engine to host auto-scaling, dynamic & high-availability web services Future use of Compute Engine for education resources and web services Access to cutting edge technology that frees us up to focus on core business
