Going Serverless the Amazon Lambda Way? Stay Calm and Monitor On! While some vendors scramble to create and sell you a fancy solution for monitoring your spanking new Amazon Lambdas, hear how you can do it on the cheap using just built-in Java APIs yourself. By exploiting a little-known fact that Lambdas aren't exactly single threaded, you can effectively identify hot spots in your serverless code. In his session at 20th Cloud Expo, David Martin, Principal Product Owner at CA Technologies, will give a live demonstration and code walkthrough, showing how to overcome the challenges of monitoring S3 and RDS. He will provide an overview of necessary Amazon Lambda concepts and discuss how to integrate the monitoring data with other tools. This presentation is for experienced Java coders, but does not require any familiarity with Amazon Lambdas specifically. Speaker Bio ... (more)

ARM Server to Transform #BigData to #IoT | @CloudExpo #IIoT #AI #ML #DX

A completely new computing platform is on the horizon. They're called Microservers by some, ARM Servers by others, and sometimes even ARM-based Servers. No matter what you call them, Microservers will have a huge impact on the data center and on server computing in general. What Is a Microserver...and What Isn't Although few people are familiar with Microservers today, their impact will be felt very soon. This is a new category of computing platform that is available today and is predicted to have triple-digit growth rates for some years to come - growing to over 20% of the server market by 2016 according to Oppenheimer ("Cloudy With A Chance of ARM" Oppenheimer Equity Research Industry Report). According to Chris Piedmonte, CEO of Suvola Corporation - a software and services company focused on creating preconfigured and scalable Microserver appliances for deployin... (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] #WebRTC Capabilities | @CloudExpo @Bit6Com #IoT #AI #UCaaS #RTC

Download Slide Deck: ▸ Here Download Slide Deck: ▸ Here Expanding WebRTC Capabilities Beyond the Typical Use Cases For basic one-to-one voice or video calling solutions, WebRTC has proven to be a very powerful technology. Although WebRTC's core functionality is to provide secure, real-time p2p media streaming, leveraging native platform features and server-side components brings up new communication capabilities for web and native mobile applications, allowing for advanced multi-user use cases such as video broadcasting, conferencing, and media recording. Download Slide Deck: ▸ Here In his session at @ThingsExpo, Alexey Goloshubin, CEO / CTO of Bit6, discussed how to utilize a flexible mobile-optimized session and signaling architecture to support p2p mesh, router (SFU) and mixer (MCU) strategies for connecting media streams. In addition, he looked at example APIs... (more)

I’m Not Scared of #DevOps | @DevOpsSummit #APM #CD #Docker #Monitoring

DevOps is speeding towards the IT world like a freight train and the hype around it is deafening. There is no reason to be afraid of this change as it is the natural reaction to the agile movement that revolutionized development just a few years ago. By definition, DevOps is the natural alignment of IT performance to business profitability. The relevance of this has yet to be quantified but it has been suggested that the route to the CEO's chair will come from the IT leaders that successfully make the transition to a DevOps model. If this still seems foreign to you, I recommend reading up on DevOps Blog from IT Revolution, the OpsCode Blog, and check out The Phoenix Project. Despite all the talk around simple monitoring tools, breaking through the walls between Dev and Ops still poses a real challenge. This is because of a misunderstanding around Operations real purp...

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)

One Size Does Not Fit All By @GENBAND | @WebRTCSummit #RTC #WebRTC

While not quite mainstream yet, WebRTC is starting to gain ground with Carriers, Enterprises and Independent Software Vendors (ISV's) alike. WebRTC makes it easy for developers to add audio and video communications into their applications by using Web browsers as their platform. But like any market, every customer engagement has unique requirements, as well as constraints. And of course, one size does not fit all. In her session at WebRTC Summit, Dr. Natasha Tamaskar, Vice President, Head of Cloud and Mobile Strategy at GENBAND, explored what is needed to take a real time communications engagement experience from a simple communication, to a truly immersive multi-layer engagement experience. Furthermore, she will explore the role of a Communications Platform as a Service (PaaS) in delivering this experience. WebRTC Summit 2017 New York, co-located with 20th Cloud... (more)

Java’s Built-In Garbage Collection | @CloudExpo #Java #Cloud #DevOps

How Java's Built-In Garbage Collection Will Make Your Life Better (Most of the Time) By Kirk Pepperdine “No provision need be made for the user to program the return of registers to the free-storage list.” This line (along with the dozen or so that followed it) is buried in the middle of John McCarthy’s landmark paper, “Recursive Functions of Symbolic Expressions and Their Computation by Machine,” published in 1960. It is the first known description of automated memory management. In specifying how to manage memory in Lisp, McCarthy was able to exclude explicit memory management. Thus, McCarthy relieved developers of the tedium of manual memory management. What makes this story truly amazing is that these few words inspired others to incorporate some form of automated memory management—otherwise known as garbage collection (GC)—into more than three quarters of the ...

A Short History of Programming – Part 2 | @DevOpsSummit #Java #AI #ML #DevOps

Code Compiled: A Short History of Programming - Part 2 By Omed Habib This is the story of software. The initial blog in this series was all about the structural formation of programming languages. We went all the way back to steampunk days to see how the framework for programming grew out of Charles Babbage’s Analytical Engine in the 1840s. We ended up with a list of the most active programming languages in use at the moment. Now we’ll take the next logical step to examine what programming has done for enterprises and SMBs. We’ll also trace the effects of shockwaves in the world of databases, communications, and mobility. Technological Change Blindness There’s a strange phenomenon known as change blindness that describes how normal people don’t notice massive, obvious changes in their environment. It can emerge from gradual shifts or very rapid transformations that ar... (more)

Java Profilers: Three Types and Why You Need All of Them | @CloudExpo #Java #Cloud

Java Profilers: Three Types and Why You Need All of Them By Darin Howard Debugging performance issues in production can be a pain and in some cases impossible without the right tools. Java profilers have been around forever, but the profilers most developers think about are only one type. Lets dive into the three different kinds of Java profilers: Standard JVM Profilers that track every detail of the JVM (CPU, thread, memory, garbage collection, etc). Lightweight profilers that highlight your application with a bit of abstraction. Application Performance Management (APM) tools used for monitoring applications live in production environments. Standard JVM profilers Products like VisualVM, JProfiler, YourKit and Java Mission Control. Standard profilers certainly provide the most data, but not necessarily the most usable information. This depends on the type of debugging tas... (more)
