Every Friday we like to highlight some of our favorite posts on Cloud Computing, service orientated infrastructure, Devops, and anything else that grabbed our attention over the week. Here are six great articles from the week of April 11th that are worth taking a look at. Enjoy!
So when I’m asked does devops mean devs doing more ops? Is it ops doing more dev? I say this: devops is the confluence of roles and duties among both software developers and IT operations professionals — many of whom are increasingly working in both jobs at various points or together in their careers. No-ops may emerge as a preferred option as organizations use and grow confidence in various PaaS offerings, as well as more openness in the clouds in general, perhaps.
The problem I have with this conclusion is it is a black & white, monolithic view of “what is cloud”. This is combined with TCO/ROI modeling that uses some pretty broad assumptions to underpin the cost model. It is often good marketing or publicity to offer polarized view of the issues, but it does not provide a real-world executable decision making capability (read “value”) for future consumer of cloud services (public or private).
The conundrum is enterprises want to leverage this technology via VM-level dynamic migration between private and public clouds. Providing a dynamic mechanism to move virtual machines around public and private server instances removes a lot of barriers around cloud computing, such as lock-in, security, governance, cost, and performance.
Mike Feinberg, EMC’s senior vice president of the cloud infrastructure group, said IT managers have to consider the performance characteristics of the application when choosing which data to put on cloud storage. “Do you want to run OLTP across the Internet? In general, the latency will not lead to a satisfied customer experience. You have to consider the application profile and the usage profile,” he said.
As importantly, consider your demand profile. Are you typically seeing frequent requests for short-running capacity or less frequent requests for long-running capacity? Public cloud economics are typically better suited to short-running workloads. Ultimately, you'll want to create an environment that provides portability between public and private clouds. This will allow you to manage IT as an optimized portfolio of options that dynamically balances across business requirements, policy and price.
You have all the in-house skills you need to manage your 1990s technology and you’d like it to stay that way.
