The Importance of Standards, IETF, and Interop to Collaboration at Cisco

2 min read

The IETF has been the birthplace of countless technologies – like SIP – that have made the Internet what it is today. Standards like SIP are hugely important to Cisco, our collaboration products, and to our newest platform, Cisco Spark. And although we may be in the “post standards era,” there are many areas where application-layer standards like SIP remain essential even as IP communications moves to cloud.

Using Cisco Spark Teams to Manage My Team

4 min read

For the past few months, I’ve been using Cisco Spark to manage the projects that my team is undertaking. As CTO in the Cisco Collaboration Technology Group, you can imagine we have some big projects to track. This has worked really, really well. It provides me a single place I can go to see all of my team’s initiatives in a single list. In the past, that list would be in a spreadsheet or a slide on my desktop, and I’d have to hunt for it. Now, with Cisco Spark it’s easy to find.

White Boarding in Cisco Spark: Always Yours, Always Live, Always Secure

5 min read

When we started working on the Cisco Spark Board over a year ago, we looked at what makes a regular analog whiteboard so effective. One thing we identified is that anyone can use it. You can walk into any conference room, walk up to a whiteboard, and use it. The whiteboard is there, it’s easy to use, and easy to make your own. But recent digital whiteboard attempts by others have failed to meet the same standard for ease of use. We knew we had to do better.

3 min read

You walk into a conference room, and you have a simple task – project your laptop screen onto the screen at the end of the conference room. Yet, until now, this simple task has been really hard. It’s time for this cable to meet its end. Today, we’ve shipped an update to Cisco Spark that will once and for all end the evil tyranny of the conference-room projection cable.

A Deeper Dive on Apple and Cisco

3 min read

With the release of iOS 10, the Apple and Cisco partnership comes to fruition. iOS 10 allows apps like Cisco Spark to be built to take full advantage of the features in iOS 10. Ultimately, the goal of this integration is to allow users to keep using the iPhone the way they are used to using it – but have the actual calls handled by Cisco Spark. This delivers the best of both worlds.

The Dirty Secret of Team Collaboration: Teams

3 min read

Cisco Spark teams is really simple. A team is a group of people working together. Anyone can create a team and then add users to it. A team can have any number of rooms, which are topic-specific rooms used by that team. Anyone in a team can create these “team rooms.” As a team member, I can easily see all the team rooms I’m not in, check them out, and join or leave them at will. That makes Cisco Spark a great experience for new users joining the app for the first time, or joining a new team.

A Lesson from Goldilocks: Messaging Security that’s “Just Right”

3 min read

We all know the story of Goldilocks and her ill-fated visit to the house of the three bears. What lesson, if any, one might take away from this story is that too much of a good thing doesn’t necessarily make it the right thing. Big chairs are big, but if they’re too big, they’re not comfortable. What is true for Goldilocks – and bear with me on the analogy – is also true when considering security technologies for business. When evaluating messaging technologies, the question to think about is: What parties should have access to content, and which should not?

The Hierarchy of SaaS Testing Needs

3 min read

Software testing. For a long time, software testing was one of those dark alleys of the software development process. Often ignored, considered as an afterthought, and staffed by “someone else” who did an important job but was outside of the core development process. Well, that has all changed. In the SaaS world – especially one […]

Devops Means “No, you cannot operate my cloud”

6 min read

One of the things I really believe strongly is that modern SaaS software development – both the practices and code it produces – are significantly different from traditional enterprise premises-based software development. Yet, I find that for people who have never built and operated a modern SaaS platform, these differences are difficult to grasp.
