In terms of search engine services. Probably won't suffer much. Will be over bing. It gives satisfying results and is (still) not much saturated by ads.

Over google maps will be tougher as bing maps are not that much developer in this region.

G+, while I use it, it won't hurt me much at this point.

SEO - well, this will hit me a bit and our clients a lot. Not a SEO company, but a lot of the clients have some sort of white hat SEO.

Will use some business apps that we use for gmail for some of our domains.

On the rest, I have migrated to MS services, thus google won't hurt mail, calendars, tasks, cloud storage that much for me.

But this is highly hypothetical situation. The chances of google disappearing is lower than ... I don't know...countries collapsing.
