Cloud this and cloud that are on the lips of every IT professional. Beyond being an overhyped buzzword, cloud computing is a technology that’s innovating the way that many businesses, from startups to enterprises, handle their IT needs. Whether it’s specific applications or a complete infrastructure, cloud technology continues to transform the IT landscape.
What is the public cloud?
Businesses have a few different cloud options to choose from: Public cloud services are run through third-party providers, whereas the private cloud is controlled directly by the business itself and distributes computing resources within the company. It’s also possible to use a combination of both. The public cloud provides a cost advantage and an overhead advantage to businesses, since you don't have to pay for equipment cost or maintenance. However, the disadvantage is that you don't have direct access to the hardware or software. It’s hosted offsite at the cloud service's facility, which can raise some security concerns.
IT as a service spurs public cloud adoption
Being able to adjust quickly to the demands of the marketplace is essential for many businesses, and with a highly connected world, infrastructure demands can change at any moment. IT as a service allows businesses to adjust their level of service as needed. If you run an ecommerce site that gets overwhelmed during Black Friday, Cyber Monday and the rest of the holidays, you can get additional server resources through the cloud without having to provision and deploy physical hardware. This agile model also allows you to control your budget, since you’ll be buying service levels instead of hardware that you may or may not get full usage out of after the traffic spikes.
Public cloud advantages in the enterprise
The public cloud offers a great deal of advantages for your enterprise-level business. Software as a Service (SaaS) provides you with cloud hosted applications that don't have to be deployed or maintained on your own hardware. All your employees need to do is login to the application through an Internet-connected device, and they can access the software. This also allows you to skip software deployment on thousands of workstations, giving your IT department a break.
Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) provide you with ways to offload the operating systems, development platforms and physical hardware to the cloud. If your headquarters doesn't have room for a fully secured data center or server room, but you need another 10 servers pronto, you can get access to those resources through a public cloud service provider.
The provider also handles all the troubleshooting, monitoring, maintenance and many other essential tasks, so you can use your IT department for more immediate needs. The equipment that public cloud providers use is often top of the line and optimized to provide you with high availability and performance, both necessary for a busy enterprise.
Although both public and private clouds have their place, public cloud adoption is dominating due to its cost efficiency, performance and availability. When you want to make your IT dollar stretch as far as possible, the public cloud is the resource on which to spend the most.
Hadoop as a Service (as offered by handful of niche vendors now) is a cloud computing solution that makes medium and large-scale data processing accessible, easy, fast and inexpensive. In his session at Big Data Expo, Kumar Ramamurthy, Vice President and Chief Technologist, EIM & Big Data, at Virtusa, will discuss how this is achieved by eliminating the operational challenges of running Hadoop, so one can focus on business growth. The fragmented Hadoop distribution world and various PaaS solutions that provide a Hadoop flavor either make choices for customers very flexible in the name of opti...

In the consumer IoT, everything is new, and the IT world of bits and bytes holds sway. But industrial and commercial realms encompass operational technology (OT) that has been around for 25 or 50 years. This grittier, pre-IP, more hands-on world has much to gain from Industrial IoT (IIoT) applications and principles. But adding sensors and wireless connectivity won’t work in environments that demand unwavering reliability and performance. In his session at @ThingsExpo, Ron Sege, CEO of Echelon, will discuss how as enterprise IT embraces other IoT-related technology trends, enterprises with i...

Wearable devices have come of age. The primary applications of wearables so far have been "the Quantified Self" or the tracking of one's fitness and health status. We propose the evolution of wearables into social and emotional communication devices. Our BE(tm) sensor uses light to visualize the skin conductance response. Our sensors are very inexpensive and can be massively distributed to audiences or groups of any size, in order to gauge reactions to performances, video, or any kind of presentation.

The true value of the Internet of Things (IoT) lies not just in the data, but through the services that protect the data, perform the analysis and present findings in a usable way. With many IoT elements rooted in traditional IT components, Big Data and IoT isn’t just a play for enterprise. In fact, the IoT presents SMBs with the prospect of launching entirely new activities and exploring innovative areas. CompTIA research identifies several areas where IoT is expected to have the greatest impact.

We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) i...

Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.

Container frameworks, such as Docker, provide a variety of benefits, including density of deployment across infrastructure, convenience for application developers to push updates with low operational hand-holding, and a fairly well-defined deployment workflow that can be orchestrated. Container frameworks also enable a DevOps approach to application development by cleanly separating concerns between operations and development teams. But running multi-container, multi-server apps with containers is very hard. You have to learn five new and different technologies and best practices (libswarm, sy...

The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session at @ThingsExpo, Ryan Bagnulo, Solution Architect / Software Engineer at SOA Software, focused on desi...
