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 applications and data to the cloud. Read on to learn about some key highlights that we found based on input gathered from our 2016 Cloud Survey of more than 700 IT professionals. Here is a quick breakdown on the respondents: 67 percent of these respondents use Java as their primary programming ... (more)

DZone Guide to Data Persistence | @CloudExpo #DataCenter #Storage

Data persistence has a way of sneaking up on developers. You start out with a simple, straightforward database that can functionally hold the data you're working with and the data you need to work with later. But as your needs change, you start to modify it here and there, until it becomes a brittle tangle of tables and keys and indexes. You need something more dynamic, but you need to retain the ability to retrieve your persistent data. Now, you're miles from where you started, and staring down the possibility of having to adopt a whole new system. That persistent data is fundam... (more)

The Textbook Definition of #ContinuousDelivery | @DevOpsSummit #DevOps

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 reali... (more)

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)

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 ...
