conclusion: continuous delivery - why microservices - what devops - how
going faster and safer
continuously delivered microservices are the natural evolution for services that need to operated at scale and also be changed frequently
also, despite what you might have heard, if you want to move
fast at scale, architecture matters
you must be this tall • rapid provisioning • basic monitoring • rapid deployment • devops culture
everything we share today is open source
byoc: bring your own culture
OperationsThe ‘Not So Secret Any More’ Sauce
cloud native operations: • api driven • service centric • change enabling
Learn BOSHhttp://mariash.github.io/learn-bosh/
• Identifiability • Reproducibility • Consistency • Agility
Why BOSH?• multi-cloud • clean separation of systems • consistent rapid provisioning • scale up/scale down • built in health monitoring • fault remediation • canary deployments
BOSH Contract•current_vm_id
•create_stemcell
•delete_stemcell
•create_vm
•delete_vm
•has_vm?
•reboot_vm
•set_vm_metadata
•configure_networks
•create_disk
•delete_disk
•attach_disk
•snapshot_disk
•delete_snapshot
•detach_disk
•get_disks

lots of other toolsyou don’t have to use mine
understanding BOSH can will make whatever you do better
cloud native runtimes: • distributed scheduling • process/containers • integrated pipelines • fault remediation • the new middleware

What even is Elastic Runtime?
service brokers

looks suspiciously like Platform as a Service
•role based access
•on demand deploy
•coordinate across services
•routing requests
•read, write data
•add/remove resources
•emit and record events
•isolate resources/failures
•measure performance/health
•detect failures
•remediate failures
•work on day 2
Platform Contract/Capabilities
ad hoc automation is a problem masquerading as a solution
A platform makes promises.
A contract allows the platform to keep promises.

understand Cloud Foundry Elastic Runtime
cloud native application: • 12 factor contract • composable • discoverable • fault tolerant
•I. Codebase
•II. Dependencies
•III. Config
•IV. Backing Services
• Build, release, run
•VI. Processes
•VII. Port binding
•VIII. Concurrency
•IX. Disposability
•X. Dev/prod parity
•XI. Logs
•XII. Admin processes
‘boot’ makes microservices easy
‘cloud’ provides composable patterns
• configuration service • service registry • service discovery • load balancing • circuit breaker • micro-proxy • api gateways
If you are one of those people who like to read books…

We are uncovering better ways of developing
software by doing it and helping others do it.
