Google announced their acquisition of Postini today. I won't rehash the deal here, but I thought Bill Burnham had a good writeup.
Bottom line: Google is moving forward with its attacks on the current business solutions (primarily Microsoft). If they do a good job incorporating Postini they can offer an more credible option for larger companies to outsource to Google Apps.
Two major points from Bill's post I want to focus on. First, Google has a propensity to offer an acquired company's products for free. This earns them good will and propels the (usually) already popular service even farther. I'll talk about this more in an upcoming post.
Second, Google is dominating the acquisition market not just by cash (which they are), but also by prestige. People are viewing Google as THE person to get bought by. That only helps them continue acquire quality companies.
Everything is moving to the cloud. Is your business model ready?
