"We are still perceived as just a hardware company and that's not true," Robbiati said.

Though there's a pocket or two of softness, cloud capex growth remains pretty strong overall.

Some tech giants are growing their cloud investments a lot faster than others. Video needs often have something to do with it.

The types of switches that Amazon reportedly wants to sell to businesses have seen limited enterprise traction to date. However, recent tech trends could make them more popular.

While many traditional enterprise IT giants are contending with weak hardware demand, things look much better for some of their chip and component suppliers.

Though it's getting a boost from buybacks, acquisitions and favorable IT spending trends, the networking giant only slightly beat estimates and offered in-line guidance.

Many large businesses are now opting to shut down existing data centers and move their contents to public clouds. Amazon is well-positioned to grab a large portion of these deals.

This earnings season is already showing that capital spending from cloud giants remains far stronger than spending from traditional carriers. That affects quite a few hardware and chip firms.

Trading is duller than usual right now.

On the whole, tech stocks had a solid earnings season. But many richly-valued names sputtered despite releasing decent numbers.

The networking giant is forecasting limited sales and earnings growth for the next few years, as hardware pressures offset software and services growth.

Most of these names have exhibited exceptional price strength.

Amazon and Google likely want a minority stake in Toshiba's flash unit rather than full ownership. Deals like that could be useful as cloud giants keep growing their spending.

With direct and indirect threats to its data center switch business mounting, it looks as if Cisco wants to make advanced software features available on cheaper hardware.

Keep an eye on the pattern of morning weakness and afternoon strength.

Poor market breadth and fewer stocks hitting 12-month highs aren't helping.

The indices may test intraday lows, which we haven't seen at this point in the day in a very long time.
