What is the difference between 2-Tier architecture and
3-Tier architecture
Answer Posted / amit k. gautam
In 2 tier architecture the application is splitted in to
two parts which is located in two machines called as client
and server that is why it is also known as client server
architecture..in this architecture the business logic
resides either with the client or with the server where
database resides, so if client machine contains the
business logic then is termed as Fat client coz it has to
look after the client related as well as business related
issues where as if business logic resides with the database
server then it is termed as Fat Server since it has to
manage the database related as well as business related
issues so some how either the client or the server
performance hampers.
in 3 tier architecture the application is physically
divided and located in to three different machine one
takes care only about clientrelated issues known as client
tier, one second takes care about all the business logic
related issus and input out taken from the client tier
known as middle tier and the third contains the database
and responsible for managing and manipulating all the
database related issues callled as database tier so this
architecture is basically used for load balancing and fault
tolerence.
