To paraphrase Kent Beck: software delivers no value apart from runtime. Ideas take physical form in hardware, virtualized only part of the way down, and someone other than the developers makes the ideas manifest. So then: ops folks are the crop's caretakers; developers design the seeds. Well, of course this isn't true. Developers don't turn pie-in-the-sky math into socially constructive math that sysadmins then make useful. No: developers write code that makes things happen. We care about runtime just as much as ops, so we need to know how our software is helping people in reality-and how it can do a better job-in order for us to refine both the ideas and the implementation. So cycle-time shortening-the metric of continuous delivery, and one of the Twelve Principles of Agile Software-is equally about users and makers. Working software delivered sooner is better for ...

Findings on Database Management | @CloudExpo #Cloud #IoT #BigData

Technical decisions around data persistence are hard, which is why we surveyed 583 IT professionals on everything from current DBMS and ORM usage to modern database engines' data structures and access patterns to storing data on a mobile device. The demographics of this survey are as follows: 69% of these respondents use Java as their primary programming language at work. 68% develop primarily web applications. 66% have been IT professionals for over 10 years. 45% work at companies whose headquarters are located in Europe, 27% in the USA. 44% work at companies with more than 500 ...

Beyond DevOps: Security vs. Speed? | @DevOpsSummit #APM #DevOps

Fail fast, fail often. Yeah, but the first failure blew up the satellite. Well, this is just a photo-sharing app..not rocket science. Okay, but your photos are accessed by users who have passwords that they probably use for other things..and aren't some photos as important as satellites? Several problems arise when the harm of software failure cannot be treated as an unbound variable. Here are some thoughts on two. I'll write more on two more (one cognitive, one computational) later. Problem 1: Identity Persists Across Non-Obviously Coupled Systems (So the Stakes Are Higher Than ... (more)

Isn't the Cloud Cool Anymore? | @CloudExpo #PaaS #Cloud #Docker #Containers

Cloud technologies have been gaining traction for some time now. Increases in connectivity throughout the computing world with the creation of more and more connected devices, including mobile and IoT technologies, as well as more and more connected applications on those devices, means cloud computing adoption is ever-increasing. Expectations regarding an application's availability are high, and solutions continue to emerge to increase availability and make scaling applications easier when a user load gets too big. New patterns, platforms, services, and software are pushing appl... (more)

The Cloud Isn't Cool Anymore | @CloudExpo #IoT #DigitalTransformation

If the cloud was once (ever) bleeding edge, now the cloud is sheer necessity for anyone doing anything on the Internet. It has changed the way we architect applications, build IT budgets, grow userbases, even write individual lines of code. As the Internet continues to lambdify, cloud services will become more specialized; but for now, how can you take advantage of the granularity, elasticity and pre-baked-ness of modern cloud services? And, on the flip side, as your applications expand outside blade-boxes and even beyond individual data centers, how do you design applications ... (more)
