why are there no microservices in this cloud native app Alice? #IBMGarage @holly_cummins

why is the cloud only saving us money, Alice? #IBMGarage @holly_cummins

microservices are not the goal #IBMGarage @holly_cummins

microservices are not the goal they are the means #IBMGarage @holly_cummins

“we’re going too slowly. we need to get rid of COBOL and make microservices!” #IBMGarage @holly_cummins

“we’re going too slowly. we need to get rid of COBOL and make microservices!” “… but our release board only meets twice a year.” #IBMGarage @holly_cummins

distributed monolith #IBMGarage @holly_cummins

distributed monolith but without compile-time checking … or guaranteed function execution #IBMGarage @holly_cummins

“every time we change one microservice, another breaks” #IBMGarage @holly_cummins

the not-actually-continuous continuous integration and continuous deployment

“we have a CI/CD” #IBMGarage @holly_cummins

CI/CD is something you do not a tool you buy #IBMGarage @holly_cummins

“i’ll merge my branch into our CI next week” #IBMGarage @holly_cummins

“CI/CD … CI/CD … CI/CD … we release every six months … CI/CD …. ” #IBMGarage @holly_cummins

“we can’t actually release this.” #IBMGarage @holly_cummins

why? #IBMGarage @holly_cummins

what’s stopping more frequent deploys? #IBMGarage @holly_cummins

“we can’t release this microservice… we deploy all our microservices at the same time.” #IBMGarage @holly_cummins

deferred wiring #IBMGarage @holly_cummins

feature flags #IBMGarage @holly_cummins

A/B testing canary deploys #IBMGarage @holly_cummins

make releases deeply boring by doing them often @holly_cummins

@holly_cummins

make recovery from failures deeply boring by doing it often @holly_cummins

automate everything

“we can’t ship until we have more confidence in the quality” #IBMGarage @holly_cummins

“we can’t ship until we have more confidence in the quality” you can fix that #IBMGarage @holly_cummins

the lockeddown totally rigid inflexible un-cloudy cloud

#IBMGarage @holly_cummins

“we’ve configured our network! #IBMGarage @holly_cummins

“we’ve configured our network! you can either access the cloud servers … or access jira. #IBMGarage @holly_cummins

“we’ve configured our network! you can either access the cloud servers … or access jira. to access both you’d need two machines.” #IBMGarage @holly_cummins

“it takes us a week to start coding.” #IBMGarage @holly_cummins

“it takes us a week to start coding.” “two days to get a repo … two days to get a pipeline …” #IBMGarage @holly_cummins

“this provisioning software is broken” #IBMGarage @holly_cummins

10 minute provision-time what we sold “this provisioning software is broken” #IBMGarage @holly_cummins

what the client thought they’d got 10 minute provision-time what we sold 3 month provisiontime “this provisioning software is broken” #IBMGarage @holly_cummins

what the client thought they’d got 10 minute provision-time the reason 3 month provisiontime 84-step pre-approval process what we sold “this provisioning software is broken” #IBMGarage @holly_cummins

#IBMGarage @holly_cummins

old-style governance isn’t going to work #IBMGarage @holly_cummins

Provider A #IBMGarage @holly_cummins

Provider A Provider B “we’re going to change cloud provider to fix our procurement process!” #IBMGarage @holly_cummins

if the developers are the only ones changing, cloud native is not going to work #IBMGarage @holly_cummins

there is a cost: developers leave #IBMGarage @holly_cummins

if you automate something, change the processes around that assume that the previously manual process is expensive or error prone. #IBMGarage @holly_cummins
