What are the translations of these IT-related terms: app, service, consulting?

• App - colloquially, this is often simply "APP" (frequently capitalized and pronounced /eɪpiːˈpiː/, not /æp/, despite its etymology). 应用[程序] is used too, though.
• Service - 服务 or 业务. Depends somewhat on the situation, but in the extremely broad sense the word is often used, 业务 often makes more sense. However, "microservice" is 微服务.
• Consulting - 咨询 or 顾问. Usually the former to describe companies and the latter to describe individual professionals, though there's some overlap (and sometimes used together as 咨询顾问).

What are the right translations of these IT-related terms into (simplified) Chinese:

app --> 应用

service --> 服务

consulting --> 咨询

Is there a reliable dictionary that includes such specialized contemporary terminology?
