DevOps is a movement for developers and operations professionals that encourages more collaboration and release automation. Why? To keep up with the faster application delivery pace of Agile. In fact, with Agile, as development teams deliver faster and in shorter cycles, IT operations finds itself unprepared to keep up with the new pace. For operations teams, managing a continuous stream of software delivery with traditional manual-based processes is Mission Impossible. Vendors have responded to DevOps requirements with more automation in their release management, delivery, and deployment tools. However, there is a key process that sits between development and operations that seems to have been given little attention: testing.
In fact, some key testing activities, like integration testing and end-to-end performance testing, are caught right in the middle of the handover process between development and operations. In the Agile and Lean playbook, I’ve dedicated my latest research precisely to Agile testing, because I’ve seen testing as the black beast in many transformations to Agile because it was initially ignored.
Airtel launched India’s first 4G LTE services in Kolkata yesterday. Airtel delivers the service using TDD technology, making it one of the few operators globally to launch a TD-LTE network. The majority of commercial LTE launches are still based on FDD technology, which begs the question: What impact will TDD have on the LTE landscape? Will TD-LTE get support from equipment manufacturers, or will it suffer a fate similar to that of WiMAX? What does it mean for operators? I believe that TDD will affect the entire mobile ecosystem. Here’s how:
Price parity between paired and unpaired spectra. Both paired and unpaired spectra will be viewed as media that deliver wireless service irrespective of the underlying technology; this will drive price parity between the spectra. The dichotomy between the FDD spectrum (used primarily for coverage) and the TDD spectrum (mainly for capacity) will disappear as technological advancements make it possible to achieve similar capacity and coverage on both spectra. Consequently, the “spectrum crunch” may diminish, as any spectrum will be satisfactory for the deployment of mobile broadband services.
