Does it make sense for a software product firm (Large or startups) to outsource the infrastructure?

Absolutely, it makes sense for a software product company to outsource its infrastructure operations. I would say, that it goes one step beyond. If the product is a hosted service, then for example RIM can take care of all the infrastructure needs. The non-core infrastructure needs of a hosted product is core for a RIM service provider.

Don't you think so guys?

I think it make sense to outsource the infrastructure because of following reasons:-

1. For companies outsourcing makes there IT cost predictable and stable;
2. On short term it will give the outsourcer a cost benefit, because insourcers are willing to invest in customers;
3. For incoursers long term deal are strategical, because they increase the shareholders value;
4. In current economical times, companies are looking for cash. So selling your IT assests gives the opportunity to create more value on share holders capital. Because IT investments are cost centres and investment in other business activities are benefit centres.

But we also see that companies are starting to see, that outsourcing is making them less agile. Because innovation with IT is a lot of times under estimated. So do a lot of large enterprices end up with an statis environment.
