Cardiff's lengthy search for a new manager ends at the request of Omer Riza a few weeks before he confirmed his landing from the tournament last month.
Karif Ramsey, Nathan Jones of Charlton Sports and Captain Wells, who had assumed temporary charge after Risa's departure, had been targeted by Cardiff during the operation.
But Barry-Murphy has emerged as better for the role of this role after advanced talks last week and will now be given the task of preparing the team for the first season of the club in the third layer since 2003.
He leaves his role in the King Power stadium after his appointment in the Ruud Van Nisstelroy room in December, where Cardiff paid compensation for his services.
Before his time in Leicester, Barry Murphy was an under -23 coach in the federation for a period of three years, which helped to develop the likes of Cole Palmer.
His work with young players was the attractiveness of the hierarchy of Cardiff, who were keen to benefit from many promising academy graduates as they were looking to return to the championship.
He will be a former midfielder with Prestton North End and Sheffield Wednesday, the first role in the front lines in Barry-Murphy since two-year talisman in Rochdale, where he also won the gameplay and the use of local talent.
In a statement, Tan said: “During the interview, Brian showed a great passion for our club because he believes in what we are trying to do.
“He knows this level that he played and managed in this standard before, as his style of play was referred to.
“Since then, he went only from strength to strength as a leader.
“He got a busy record in the development of youth after he trained some of the brightest youth horizons in the United Kingdom, many of whom are now playing at the top of the game.
“It brings enthusiasm, vitality and an exciting look for football today, while looking to play a striker's style that is sure that our fans are sure to enjoy.
“It is a mixture of all the wonderful Brian talents that make him the right man to take us forward in this next chapter.”
