Earlier this week we held a webinar - "7 Myths about Agile Testing - Busted!" - that generated a lot of good questions about how best to conduct testing while in a fast-paced, fluid Agile environment. We didn't have time to get to all the questions, so the Aricent experts who ran the webinar, Gopinath Ramachandran, Gayatri Singla, and Srimanta Kumar Purohit, have gone through the unanswered questions and answered them below.

In my last blog post, “Race to the Cloud,” I talked about cloud strategies for Tier-1 telcos. Essentially, they’re big enough to be able to take the risk of hosting their own cloud data centers (telco’s “private cloud”), while gradually climbing up the cloud-chain from IaaS-provider to PaaS-provider to SaaS-broker/communication-and-collaboration-as-a-service provider. But, what about the smaller players? They must be shying away from hosting cloud data centers (otherwise they would have been in the news) because of the kind of investment they need to set up the cloud infrastructure. However, they can’t ignore the fact that the cloud-model is knocking at their door and they really can’t afford to lose the business opportunities.

Global mobile data traffic tripled for the third year in a row in 2010, and, according to Cisco, the total mobile data traffic will grow to 6.3 exabytes per month by 2015, a massive 26-fold increase over 2010. This unprecedented demand for bandwidth puts huge strains on all parts of the mobile ecosystem, and to address it a plethora of technologies are coming on line, such as EV DO, HSPA +, LTE, and now LTE-Advanced. Additional benefits come from multi mode devices, intelligent small cells (which include distributed processing and smart antennas, such as femtocells), and heterogeneous network topologies that spread the load across various types of base stations. While helping address bandwidth issues, these innovations come with a downside: highly complex networks that are expensive to manage.

Traditionally, telcos have sold “communication” as the application over an underlying “connectivity” capability. However, the advent of an all-IP telecom network has forced the telcos to open up their “connectivity” capability. Today, they sell both “connectivity” as well as “communication.” But, the market has been smart enough to quickly commoditize the telcos’ “connectivity” service, and today, connectivity has become the commoditized infrastructure for a buzzing marketplace camped on the Cloud (and the Internet in general).

Failure is all the rage these days. Recently, from Harvard Business Review alone, we have David Simms talking about the power of positive failure (and Scott Anthony's response), and the excellent series on lessons from the military often touches on the topic.
