Open Source Tool Chains for Continuous Testing The goal of Continuous Testing is to shift testing left to find defects earlier and release software faster. This can be achieved by integrating a set of open source functional and performance testing tools in the early stages of your software delivery lifecycle. There is one process that binds all application delivery stages together into one well-orchestrated machine: Continuous Testing. Continuous Testing is the conveyor belt between the Software Factory and production stages. Artifacts are moved from one stage to the next only after they have been tested and approved to continue. New code submitted to the repository is tested upon commit. When tests fail, the code is rejected. Subsystems are approved as part of periodic builds on their way to the delivery stage, where the system is being tested as production ready. ... (more)

DevOps Five Years Later at @DevOpsSummit | #DevOps #APM #Microservices

DevOps Five Years Later: What Does the Future Hold? After more than five years of DevOps, definitions are evolving, boundaries are expanding, ‘unicorns' are no longer rare, enterprises are on board, and pundits are moving on. Can we now look at an evolution of DevOps? Should we? Is the foundation of DevOps ‘done', or is there still too much left to do? What is mature, and what is still missing? What does the next 5 years of DevOps look like? In this Power Panel at DevOps Summit, moderated by DevOps Summit Conference Chair Andi Mann, panelists looked back at what DevOps has become, and forward at what it might create next. Panelist Bios: Randy De Meno joined Commvault in 1994 and initiated Commvault's direction into the heterogeneous Data Management segment of the industry.

Languages for 2017 | @DevOpsSummit @AppDynamics #DevOps #JavaScript

The Most Popular Programming Languages for 2017 By Jordan Bach It’s hard to believe that it’s already 2017. But with the new year comes new challenges, new opportunities—and, of course—new software projects. One of the most important questions beginner, intermediate, and advanced coders all have to answer before they begin their next project is which programming language to use. Instead of reaching for an old favorite, pause for a moment to consider the options. There are no perfect languages, so it’s important to take the time to understand the tradeoffs. When you decide on a language, you also determine what libraries and tools you have at your disposal, the pool of candidates you can hire, the availability of documentation, and much more. In this article, we examine the top programming languages from leading industry sources to help you make an informed decision ... (more)

The Best Programming Languages | @CloudExpo #IoT #AI #API #Java #Python

Five of the Best Programming Languages and Frameworks for a Small Business Choosing a programming framework for a small business can be overwhelming- there are so many. Here are a few of the best choices, to help you get started. Ask a room of ten developers which programming framework is the ‘best on the market,' and you're liable to receive ten different answers. Each developer will sing the praises of a different language, and each one will very probably feel that theirs is the only logical choice. The most confusing thing, though? Each and every one of those developers will be correct. Wait, what? I'll be blunt: there is no universal programming framework. The language your organization should work with - whether it's for web development, mobile development, or traditional development - depends entirely on your unique situation. The perfect choice for one busine... (more)

Java vs. Python: Which One Is Best for You? | @DevOpsSummit #APM #Java #Python

Java vs. Python: Which One Is Best for You? By Kevlin Henney Few questions in software development are more divisive or tribal than choice of programming language. Software developers often identify strongly with their tools of choice, freely mixing objective facts with subjective preference. The last decade, however, has seen an explosion both in the number of languages used in production and the number of languages an individual developer is likely to employ day to day. That means that language affiliations are sometimes spread more loosely and broadly across different codebases, frameworks, and platforms. Modern projects and modern developers are increasingly polyglot—able to draw on more languages and libraries than ever before. Informed choice still has a part to play. From that bustling bazaar of programming languages, let’s narrow our focus to two survivor... (more)

[slides] @Docker Deployments | @DevOpsSummit @JPetazzo #SDN #DevOps

Orchestrating Distributed Deployments with Docker and Containers Thanks to Docker, it becomes very easy to leverage containers to build, ship, and run any Linux application on any kind of infrastructure. Docker is particularly helpful for microservice architectures because their successful implementation relies on a fast, efficient deployment mechanism - which is precisely one of the features of Docker. Download Slide Deck: ▸ Here Microservice architectures are therefore becoming more popular, and are increasingly seen as an interesting option even for smaller projects, instead of being reserved to the largest, most complex application stacks. But those architectures bring a new set of challenges. Breaking down an application into many smaller components means that each individual piece is simpler and easier to reason with; but now we need something to tie all thos... (more)

A Short History of Programming | @DevOpsSummit #Java #AI #ML #DevOps

Code Compiled: A Short History of Programming - Part I By Omed Habib There are more than 2,500 documented programming languages with customizations, dialects, branches, and forks that expand that number by an order of magnitude. In comparison, the Ethnologue: Languages of the World research officially recognizes 7,097 official language groups that humans use to communicate with each other all around the world. It can be hard to grasp what’s happening in the world of programming today without a solid grounding in how we got here. There are endless fascinating rabbit holes to disappear down when you look back over the past 173 years of programming. This abstract can only give you a high-level review with a strong encouragement to follow any thread that engages you. The Prehistory of Programming Ada Lovelace, daughter of the poet Lord Byron, is generally recognized as the... (more)

Is Blockchain the Ultimate Open Source Disruptive Technology? | @CloudExpo #Cloud #FinTech #Blockchain

Is Blockchain the Ultimate Open Source Disruptive Technology? Fred Wilson of Union Square Ventures has been talking a lot about the blockchain recently, so I decided to learn more about it.  I read the Marketing the Blockchain e-book, watched The Grand Vision of a Crypto-Tech Economy video and the video keynote of Overstock CEO Patrick Byrne at the Bitcoin 2014 conference, and did some more research on my own.  While far from an expert, I do see some interesting similarities to the adoption of open source software. Here’s what I’ve learned — please comment and tell me if I’m wrong: What’s the Big Deal about the Blockchain? Blockchain is a distributed ledger system using crytography and open source software. The goal of the blockchain is to allow anonymous and secure record-keeping. But here’s the big thing: instead of those records being kept in one central, alleged... (more)
