Daily Video: Chambers to Step Down as Cisco CEO, Replaced by Robbins

Today's topics include senior management changes at Cisco, an announcement from CoreOS about container technology for application virtualization, EMC announces a new content management platform and former Hewlett-Packard CEO Carly Fiorina formally announces her run for president.

Cisco Systems CEO John Chambers will step down in July and will be replaced by Chuck Robbins, currently the company's senior vice president of worldwide operations.

Cisco's board of directors made the announcement May 4, saying Chambers, who took over as CEO in 1995, will resign from the post July 26, though he will become executive chairman and continue to serve as chairman of the board. Robbins joined the board May 1.

Chambers will leave a company he joined in 1991 before assuming the CEO duties four years later. During his tenure, Chambers has overseen the growth of Cisco's annual revenue from $1.2 billion to about $48 billion.

In the growing world of container technology for application virtualization, Docker isn't the only game in town. CoreOS announced an expansion of its application container specification (appc) effort to include the support of Apcera, Google, Red Hat and VMware.

CoreOS builds its own container-optimized operating system that uses Docker, although CoreOS developers have not been entirely happy with the way Docker has been progressing. With appc, the basic idea is to build an open-source specification for containers that isn't tied to any one vendor or technology.

EMC on May 4 announced Project Horizon, a new cloud business content management platform. The platform enables administrators to manage a company's content for internal use or for marketing purposes.

It also contains an apps marketplace, managed by EMC, which will include EMC- and partner-built apps designed to serve specific business needs. The lists of products that EMC will deliver through Project Horizon include editing, deduplication, cataloging and others to produce and manage business content.

After months of speculation, former Hewlett-Packard CEO Carly Fiorina made her presidential bid official May 4, announcing her intentions on Twitter and launching a Website for her campaign.

Fiorina announced her candidacy the same day that conservative firebrand Ben Carson also entered the race for the Republican nomination, with the two joining three others—Sens. Marco Rubio of Florida, Ted Cruz of Texas and Rand Paul of Kentucky.
