“the cloud native-ness comes from these network connections” (no, it doesn’t!)

Slide 50

Slide 50 text

the pain comes from these network connections

Slide 51

Slide 51 text

remember the distributed computing fallacies? the pain comes from these network connections

Slide 52

Slide 52 text

remember the distributed computing fallacies? 1. The network is reliable; 2. Latency is zero; 3. Bandwidth is infinite; 4. The network is secure; 5. Topology doesn't change; 6. There is one administrator; 7. Transport cost is zero; 8. The network is homogeneous. the pain comes from these network connections

@holly_cummins #JBCNConf reasons not to do microservices • small team • not planning to release independently • don’t want complexity of a service mesh - or worse yet, rolling your own • domain model doesn’t split nicely

Slide 55

Slide 55 text

@holly_cummins #JBCNConf “every time we change one microservice, another breaks” true story

Slide 56

Slide 56 text

@holly_cummins #JBCNConf distributed != decoupled

Slide 57

Slide 57 text

@holly_cummins #RedHat how do you know if you’re decoupled?

Slide 58

Slide 60

Slide 60 text

@holly_cummins #RedHat “we made our pipeline enforce releasing all our microservices at the same time.” true story

Slide 61

Slide 61 text

@holly_cummins #RedHat can you even deploy at all?

Slide 62

Slide 62 text

@holly_cummins #RedHat can you even release at all?

Slide 63

can you release often? v1.0 v1.0 v1.0 v1.0

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

Slide 69

Slide 69 text

@holly_cummins #JBCNConf by the way, you also can’t buy devops

Slide 70

Slide 70 text

@holly_cummins #JBCNConf (Matt was not serious, before anyone takes this out of context and decides he’s an awful person and they should hate him.)

Slide 71

Slide 71 text

@holly_cummins #JBCNConf if you only want a small amount of devops …   you can’t buy a devop

Slide 72

Slide 72 text

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

Slide 73

Slide 73 text

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

Slide 74

Slide 74 text

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

Slide 75

Slide 75 text

@holly_cummins #JBCNConf continuous. I do not think that word means what you think it means.

Slide 76

Slide 76 text

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

Slide 77

Slide 77 text

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

Slide 78

Slide 78 text

@holly_cummins #RedHat “we can’t actually release a microservice without the release board and all the other microservices need to be released at the same time and the manual QA cycle and the release checklist and the incantations and the death march and the sacrificing a goat and the spreadsheet and the moon being in the right phase and…”

Slide 79

Slide 79 text

@holly_cummins #RedHat releases are like brushing your teeth: if it hurts do it more often

Slide 80

Slide 80 text

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

Slide 81

Slide 81 text

@holly_cummins #RedHat “our tests aren’t automated”

Slide 82

Slide 82 text

@holly_cummins #RedHat “we don’t know if our system works”

Slide 83

@holly_cummins #RedHat if you’re going to be spaghetti, at least be tested spaghetti

Slide 84

Slide 84 text

@holly_cummins #RedHat

Slide 85

Slide 85 text

@holly_cummins #RedHat … and use contract tests

Slide 86

Slide 86 text

@holly_cummins #RedHat … and use contract tests seriously, use contract tests

Slide 87

Slide 87 text

@holly_cummins #RedHat “we can’t release because we don’t seem to be able to actually change things”

Slide 88

Slide 94

Slide 94 text

@holly_cummins #RedHat integration layer (“panicked sandwich”) database layer front-end layer our layer (“business logic”) we can’t make progress because we need a change to the database

Slide 95

Slide 98

Slide 98 text

@holly_cummins #RedHat integration layer (“panicked sandwich”) database layer front-end layer our layer (“business logic”) oh wait … every change needs a front-end change too uh… we can’t release our cool new stuff because we’re dependent on a change in the integration layer we can’t make progress because we need a change to the database
