The router vendors continue to amass cloud-computing arsenals, through acquisition and partnerships, as evidenced with two announcements today.

Cisco Systems Inc. (Nasdaq: CSCO) is partnering with software giant BMC Software Inc. (NYSE: BMC), offering a bundle that includes Cisco's Universal Computing System (UCS) with BMC's Cloud Lifecycle Management software, a package being called the Integrated Cloud Delivery Platform. (See Cisco, BMC Team Up.)

Each side is doing what it would normally do; the difference is that the services are being offered together, extending the all-in-one angle that Cisco has been working with UCS.

It also gives Cisco more clout in big, big clouds, the multi-tenant type. Cisco and BMC can "break out a chunk of the cloud and keep it unique for one customer," says Simon Aspinall, Cisco senior director of service provider marketing.

Juniper Networks Inc. (NYSE: JNPR) announced this morning that it has acquired security vendor Altor Networks Inc. (See Juniper Acquires Altor for $95M.)

Juniper already has plenty of security products, but as executive vice president Mark Bauhaus explains on the company's blog, Altor adds the virtualized dimension, providing control over the traffic that's going from one virtual machine to another.

VentureBeat notes that Altor also offers security for a host computer that runs multiple operating systems. The acquisition gives Juniper one security package that can work with the host's multiple personalities.

Juniper had already invested in Altor. Minus that stake, the acquisition cost $95 million cash. (See Altor Raises $10M.)

Just last week, Cisco picked up LineSider Communications, a management software company. Add that to today's announcements, and it's clear that the router vendors are amassing the enterprise capabilities that haven't been their purview. (See Cisco Reels In LineSider.)

That's likely to lead to more deals. Speaking of which: Deloitte thinks cloud-computing companies will do well in what should be a deal-heavy 2011, as IT Pro reports.
