All rights reserved. | Confidential FULLY AUTOMATED PROVISIONING OF CLOUD SERVICES • We can already fully automate provisioning of Oracle Cloud services from command line using REST APIs • It’s a good thing to do as most organisations have more than one cloud environment: – Consistency across dev/test/production environments – Should save administrators time overall – Reduces the reluctance/inertia for creating new environments – Automated provisioning can be part of CI/CD pipelines (especially with metering like Universal Credits) 5

All rights reserved. | Confidential FULLY AUTOMATED PROVISIONING OF CLOUD SERVICES • A cloud environment typically consists of several of the following: – Storage containers for backups – SSH keys – PaaS instances, such as databases • Cloud console screens simplify provisioning but are still lots of parameters to enter – E.g. 47 (some duplicates) for a 2 node SOA CS cluster and a single instance database • Most organisations have a limited number of platform patterns (e.g. clustered, non- clustered, large, small) with a few parameters to distinguish them: – ID (e.g. number) – Tier (dev, prod, etc) – Environment pattern – Front-end details6 My goal is (after customer setup) to only need these parameters for any new environment creation

All rights reserved. | Confidential FULLY AUTOMATED PROVISIONING OF CLOUD SERVICES • There are existing tools to help you build this, e.g. • Using provisioning REST APIs is not trivial though – APIs change periodically – Error messages can be “obscure” – Less parameter validation than through the console – Powerful – can leave underlying artefacts in a strange state • Some people have built this into a product, e.g. 7

All rights reserved. | Confidential PROVISIONING AS CLOUD STACKS Cloud provisioning is a significant time-saver compared to on-prem (even when compared to scripted approaches) • A cloud stack groups together multiple service types, in this case SOA, DB and storage • Managed as a single unit – create/delete, start/stop • Custom templates allow you to control config, e.g. topology, sizing, naming conventions • Configured via Oracle-provided or custom templates 11 Dec 2016

All rights reserved. | Confidential WHAT IS AN ORACLE CLOUD STACK? • Intended for multiple PaaS services (“stack”) but can use for just one – Why would you do build a “stack of one”? • To simplify • To standardise • Even one service has dependencies, e.g. storage • Can simplify provisioning, especially from console – Even better now that parameters can be hidden (i.e. changed from command line if required) 12

Oracle-supplied templates cover lots of products and are a great starting point, but… • I wanted to change: – IP Networks instead of Shared Network – Separate backup containers – VM flavours (e.g. high memory usage) • Plus I had customer-specific requirements: – To enforce standards – To minimise env-specific information needed (e.g. have standard storage user & DB SID naming) 19

All rights reserved. | Confidential CLOUD STACK MANAGER TIPS • You have to install PSM first – try Windows Subsystem for Linux #WSL ☺ • As ever don’t try to change too much at once • Use an editor with a YAML syntax highlighter / linter • Template is a one-use starter – can change later without affecting instances • Use Oracle-supplied templates as a starting point (tested baseline) • Note: when delete a Cloud Stack it doesn’t delete object storage – tidy up yourself, e.g. with REST API <= this was changed in 18.1.6: • Non visible parameters added in 18.1.6 27

All rights reserved. | Confidential SUMMARY • A cloud stack is a set of Cloud Service instances, managed as one • Stack manager can easily cut down number of parameters you need & improve consistency • Cloud Stack Manager is production-ready for many types of Cloud Service types Remember: Cloud Stack is not silver bullet for all automation – you still usually need to automate customer-specific configuration of platform (e.g. TLS certificates) 29
