Agenda
Čo je to ten DevOps?
DevOps predstavuje zmenu IT kultúry, zameranú na rýchle dodávanie
služieb prostredníctvom adopcie agilných a štíhlych postupov v kontexte
systémovo orientovaného prístupu.
DevOps kladie dôraz na ľudí (a kultúru) a snaží sa o zlepšenie
spolupráce medzi vývojovými a prevádzkovými tímami.
Nasadenia DevOps využívajú technológie – hlavne automatizačné
nástroje, ktoré môžu využívať čoraz viac programovateľnú a dynamickú
infraštruktúru.
devops je ako sex tínejdžerov. každý o tom hovorí, ale nikto nevie ako
sa to má robiť, každý si myslí že to tí ostatní robia, tak mnohí tvrdia, že
to tiež robia.
môj vzťah k devopsu je zase ako z románu ružovej beletrie – dlho sme
sa prehliadali, potom sme sa náhodne zoznámili, zahoreli sme niečím,
čo som pokladal za lásku, ale skutočne som sa zaľúbil, až keď sme sa
odlúčili.

▪ Slovensko je konzervatívne v prijímaní
agility a nových postupov...
Prečo by ma DevOps malo zaujímať?

DevOps – ohrozuje outsourcing?
... veľa firiem by chcelo byť inovátormi, ale bez dev
to proste nejde. ak si kúpite hotové riešenie od
softvérovej firmy alebo systémového integrátora na
kľúč, kompletne stratíte agilitu...
... zapadnete v blate drahých a pomalých change
requestov u externého dodávateľa...
... kedysi stačilo meniť sa pomaly, teraz to nestačí...

Základné omyly
▪ DevOps je len pre cloudové spoločnosti
▪ DevOps je len pre developerov
▪ Ops sa budú musieť naučiť kódovať
▪ DevOps je len pre cloudové nasadenia
▪ Funguje len pre malé nasadenia, ale naše
je komplexné
DevOps: tri základné oblasti
Prínosy DevOps

30x rýchlejšie
Majú 60x
menej zlyhaní
▪Robte _____________ kontinuálne.
– plán a meranie
– vývoj a test
– integrácia a delivery
– release a nasadenie
– monitoring a optimalizácia
– budujte opakovateľné, stabilné procesy

Best Practice: Feature Flags
▪ Všetok kód je nasadený, ale FF kontrolujú zobrazenie
▪ FF poskytujú runtime kontrolu na úroveň jednotlivého užívateľa
▪ Užívatelia môžu byť pridaní alebo odobraní bez redeploymentu
▪ Umožnia dark launch
▪ Mechanizmus na progresívne experimentovanie a úpravy
