“the microlith wall"
borrowing some tools of
thinking
Firms exist when the transaction cost of doing something within the firm, even with all its overhead, is lower than than cos t o f do ing th ings through a marketplace of free agents.
“[this works well until] the costs of organising an extra transaction within the firm become equal to the costs of carrying out the same transaction by means of an exchange on the open market or the costs of organising another firm"
back to microservices
at first
“just add to the monolith"
“create a new service for it"
transaction cost
inverse conway
“just add to the monolith"
“create a new service for it"

making the "wrong" thing harder is ok in
the beginning
making the "right" thing easier is what
takes you to excellence

a proposal
back to economics
"For example, McDonald's can produce both hamburgers and French fries at a lower average expense than what it would cost two separate firms to produce each of the goods separately. This is because McDonald's hamburgers and French fries are able to share the use of food storage, preparation facilities and so forth during production."
monoliths benefit from economies of scope
microservices benefit from economies of scale
so I need to have answers for all
these questions before starting?
nope.
remember, you have a business to build.
