TASKS TO PERFORM

86. IS THIS PLUGGABLE?

87. LIKE ELECTRICITY

88. THINK ABOUT ELECTRICITY AT THE
BEGINNING OF 20TH CENTURY

89. OWN ELECTRICITY PRODUCTION

90. PRODUCTION LINE IS POISONED BY
ELECTRICITY PRODUCTION

91. DEEP DEPENDENCY LINKING

92. BUY ELECTRICITY, NOT A POWER
PLANT. IT’S A COMMODITY

93. DO YOU HAVE AN ELECTRICITY
PROJECT?

94. BUT TODAY YOU HAVE HOSTING
PROJECTS

95. BECAUSE THERE IS NO INDUSTRIAL
WAY TO DO IT

SERVICE

106. WORK OF DEVELOPER HAS TO STOP AT
GIT PUSH

107. APPLICATIONS HAVE TO DEPLOY

108. (WITHOUT DOWNTIME)
BECAUSE YOU NEED TO BE ABLE TO
PUT NEW VERSIONS IN PRODUCTION
EASILY

109. It’s nonsense to be unable to do continuous deployment
AVOID THE MAINTENANCE TIME

110. USE BUILD SYSTEMS
