SD-WAN interest grows as enterprises become more cloud-ready, research finds

As enterprises are embracing the cloud, SD-WAN is more likely to be on the table for their technological roadmaps.

This is the primary finding from a survey conducted by analyst firm IHS Markit. The WAN Strategies North America study found almost three quarters (74%) of organisations polled conducted SD-WAN lab trials in 2017, with many of these moving into production trials and, eventually, live production, this year.

Investments in wide area networks more generally continue undimmed, with the adoption of...

Get smart: Achieving data-driven insights through a modernised IT infrastructure

Many organisations are beginning to rely on real-time insights to drive mission-critical business decisions, but a recent study by Accenture and HfS Research states that nearly 80% of companies can’t make data-driven decisions due to a lack of skills and technology. Based on a global survey, respondents reported that 50% to 90% of their data is unstructured and largely inaccessible.

As Debbie Polishook, group chief executive of Accenture Operations has commented: "Organisations need...

Putting the D in VDI: How virtual desktop infrastructure got its desktop back

The point of virtual desktop infrastructure (VDI) is to offer employees anytime, anywhere accessibility to your organization’s applications and data. VDI is a “desktop away from the desktop.” The problem is that more emphasis has had to be placed on the infrastructure part of VDI due to outdated technology that creates complexity. But newer VDI technology is about to restore the desktop to its rightful place.

A promising beginning

In a tradition dating back more than a quarter of a century,...

Why Kubernetes networking is hard – and what you can do about it

 

History tells us that networking is always the last piece of the puzzle. From mainframes, to virtual machines, and now with containers, providing compute and storage are the first two steps before the realisation sets in that all these little entities have to all communicate with each other.

For most of the last 30 years, that communication has been facilitated over Ethernet where different ends of a communication at the application layer bind to each other using IP addresses and port numbers. But...

Keeping the multi-cloud world safe: Ensuring control and visibility

The world is going multi-cloud. Organisations seek the efficiency, speed, scalability and reduced costs that cloud promises and are rapidly moving applications and data into more hybrid environments – including to more than one cloud.

According to Cisco’s most recent Global Cloud Index, data centre application growth is exploding in this new multi-cloud world. By 2021,...

Can the cloud go all the way to the edge?

There is lots of conversation in the industry at the moment around the impact that edge computing is going to have on the cloud and specifically if it is going to kill the cloud, or at the very least impact its ability to cope.

With the proliferation of the Internet of Things (IoT), and the predicted future ubiquity of sensors, the cloud and associated technologies in their current state won’t be able to cope with the sheer amount of data being generated by machines – and won’t be able to keep up with the...

Why cloud-native virtual network functions are important for NFV

Virtual network functions (VNFs) are software implementations of network function equipment packaged in virtual machines, on top of commercial off the shelf hardware NFV infrastructure. VNFs are a core part of NFV – as we know the base of NFV was to virtualise the network functions and software based to reduce cost and gain full control over network operations with added agility and flexibility benefits. We can say that the majority of NFV operations are focused towards how VNFs can be served in NFV...

A guide: SD-WAN as a tool for your cloud-first strategy

Following a cloud-first strategy is great for IT budgets and business agility but places new demands on the network. Cloud first can significantly impact network operations, as an increasing percentage of traffic flows directly to, from, and between clouds.

Unfortunately, the traditional MPLS architecture simply cannot support the economics or agility required for a cloud-first strategy. MPLS can be costly and time-consuming to configure and requires that Internet-bound traffic be backhauled to a centralized...

Why blockchain holds ‘great promise’ for securing connected devices and systems

Blockchain technologies hold ‘great promise’ for securing connected devices and systems, according to a new paper from the Cloud Security Alliance (CSA).

The report, put together by the alliance’s Blockchain/Distributed Ledger Technology Working Group and titled ‘Using Blockchain Technology to Secure the Internet of Things’, explores the intersection between the two technologies, as well as giving an extensive overview of deployment options.

As the report puts it, a cloud-enabled...

Why hyperscale cloud providers lead the server market

IT vendor revenue in the worldwide server market increased 19.9 percent year-over-year to reach $17 billion in the third quarter of 2017 (3Q17), According to the lattest market study by International Data Corporation (IDC).

While demand from cloud computing service providers has driven overall market performance in the past, other areas of the server market are beginning to show growth. Worldwide server shipments increased 11.1 percent year over year to 2.67 million units in 3Q17.

Server systems market...
