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 fundamental to nearly any operation that utilizes database management systems (DBMS), but while the growth of dynamic data has led to sophisticated and reliable new relational management systems, real-world techniques for optimal data storage and retrieval have sometimes been lost in the shuffle. ...

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 ...

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 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)

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)
