Major trends in the architecture of distributed control systems are not adopted overnight. At present, ARC Advisory Group is following several ongoing trends in DCS. These range from highly mature ones, such as remote I/O enclosures to newly emerging trends such as the virtualization of control functionality. Different DCS suppliers will be at different stages in adopting these trends in their own product lines. However, looking over the entire market, we see several key trends that build on each other. Several others are now barely visible but should become quite important in the market over the next three to five years. Overall, these trends are driven by very few factors. One factor is the growing capability of remote I/O and enclosures. These have evolved from simple field junction boxes to complete control systems. Another technological driver is growing use of virtualization in different areas of DCS products and markets.

Security Cited as Top Public Cloud Inhibitor

Article | March 25, 2020

Barracuda Networks commissioned a survey to explore the enterprise digital transformation in which the use of public cloud computing platforms is key, seeking to gauge the impact of security roadblocks and how they can be overcome. The unsurprising results confirmed that organizations are indeed moving their computing infrastructure to public clouds, and that security is the top concern restricting faster adoption. What's more, the number of organizations that report being attacked by cybersecurity villains has increased, affecting three quarters of respondents, up from 56 percent in 2017.

Cisco and Microsoft partner on cloud IoT stuff

Article | March 25, 2020

The move was announced in a Microsoft blog, which somehow resisted the urge to use the term ‘end-to-end’ a lot. The thinking is that Microsoft’s Azure IoT platform is great at the datacenter end of things and Cisco is pretty hot at the edge. Industries increasingly want a bit of both from their IoT so this partnership has been created to provide that.Using software-based intelligence pre-loaded onto Cisco IoT network devices, telemetry data pipelines from industry-standard protocols like OPC-Unified Architecture (OPC-UA) and Modbus can be easily established using a friendly UI directly into Azure IoT Hub,” explains the blog, “Additional telemetry processing is also supported by Cisco through local scripts developed in Microsoft Visual Studio, where filtered data can also be uploaded directly into Azure IoT Hub. This collaboration provides customers with a fully integrated solution that will give access to powerful design tools, global connectivity, advance analytics, and cognitive services for analyzing IoT data.

Virtualization Can Help Substantially Reduce Computing Costs

Article | March 25, 2020

Businesses use a lot of technology to keep themselves competitive and Businesses use a lot of technology to keep themselves competitive and operationally efficient. One way that organizations use to make their technology infrastructure more accessible is through the use of virtualization. Let’s discuss what virtualization is, how it benefits businesses, and some examples of how you might consider leveraging virtualization to your company’s benefit. Virtualization for Hardware and Software Virtualization in its most basic sense is taking something and making it virtual. In regards to hardware and software, it involves taking these parts of your technology infrastructure and making them available in a virtual environment. Virtual applications and hardware solutions can be deployed to the cloud so that they can be accessed by any online device. Some examples of virtualization might include creating virtual machines, like workstations and server units, that are hosted in a virtual environment for as-needed access

VMware Adds More Hybrid Cloud Features to Network Virtualization Tech

Article | March 25, 2020

VMware on Wednesday announced new versions of its NSX-T and vRealize Network Insight software that simplify network virtualization and improve network visibility and security. The two products, along with VMware SD-WAN by VeloCloud, make up VMware’s Virtual Cloud Network, the company’s portfolio of software defined networking (SDN) technologies. It allows enterprises to deploy and manage network connectivity and security from internal data centers and branch locations to multi-cloud environments. While previous versions of NSX-T network virtualization and security software for data centers added support for public clouds and platforms that run containers on bare metal, the latest release, NSX-T 3.0, adds new networking and security features that improve the company’s vision to deliver a public cloud experience on premises, VMware executives said.
