Exploring WAN data acceleration: Is edge computing really necessary?

Most traditional forms of dealing with network and data latency, as well as packet loss, fall short of their promise. This includes WAN optimisation. SD-WANs are great, but their performance can also be improved by adding a WAN data acceleration layer. With the growth of the Internet of Things, therefore, organisations are looking for new ways to reduce the impact of latency and packet loss.

SD-WAN and cloud: A marriage made in heaven or a match made in hell?

Paul Stuttard, director of Duxbury Networking, argues in South African online magazine IT Web that SD-WAN is a marriage made in heaven. Why? SD-WAN technology has the ability to optimise the cloud, while speeding up access to cloud-based applications, he claims. Stuttard further explains that just 10 years ago organisations were advised to prepare for the impact of cloud computing on their networks.

Is hyperconvergence really key to your data centre cloud strategy?

Vendors often like to create a new name for an existing piece of technology that is essentially made up of the same components and fulfils the same functions. This is because of factors such as the competitive pressure to keep customers interested: application service provision is more commonly known today as the cloud, while converged infrastructure has led to hyperconverged infrastructure.

Sometimes there are actual technological differences between products, but this isn’t always the case....

Anything you can do, AI can do better: Making infrastructure smarter

(c)iStock.com/pixtum

Data flows and artificial intelligence (AI) are changing the globalised supply chain by sending data around the world. Using the cloud as the data transport method requires more efficient data acceleration. AI is infiltrating many places, and it’s not just about replicating human performance and taking jobs, or streamlining processes. It also helps make technology smarter.

AI can be part of IT infrastructure. David Trossell, CEO and CTO...

Maximising the potential of the Industrial Internet – through the right networks

(c)iStock.com/DrAfter123

Computer-aided design (CAD) and computer-aided engineering (CAE) often use extremely large files, which make remote working and collaboration difficult to achieve. Most businesses are able to work remotely with laptops, smartphones and tablet PCs, but the processing power required to create, store and share CAD files over a wide area network is often prohibitive. Yet with the power of the internet they can work remotely and collaboratively.

Data resilience: Why CEOs and CFOs need to understand the CIO agenda

(c)iStock.com/Akindo

The CIO agenda changes each year, albeit not drastically. In 2015 part of their focus was on hybrid cloud spending, but this year research and analyst firm Gartner says that it’s now about how they enhance the power of digital platforms. The company’s ‘Building the Digital Platform: Insights From the 2016 Gartner CIO Agenda Report’ says: “As digitalisation moves from an innovative trend to a core...

After the flood: Why IT service continuity is your best insurance policy

(c)iStock.com/monkeybusinessimages

The severe floods that hit the north of England and parts of Scotland in December 2015 and January 2016 devastated both homes and businesses, and led to questions about whether the UK is sufficiently prepared to cope with such calamities.

On December 28, the Guardian newspaper went so far as to say that the failure to ensure that flood defences can withstand the unprecedented high water levels, would cost at least £5bn. Lack of...

Disaster recovery: How to reduce the business risk at distance

(c)iStock.com/natasaadzic

Geographic distance is a necessity because disaster recovery data centres have to be placed outside the circle of disruption.

The meaning of this term depends on the type of disaster. This could be a natural phenomenon like an earthquake, a volcanic eruption, a flood or a fire. Calamities are caused by human error too; so the definition of the circle of disruption varies. In the past, data centres were on average kept 30 miles apart as this...

Accelerating cloud storage and reducing the effects of latency

(c)iStock.com/ktsimage

Over a number of years there has been a long and hard fought battle to secure the ability to ‘accelerate anywhere’ any data type to, from and across a cloud area network (ClAN) to allow fast access to applications, or to secure data as a part of a back-up and archiving strategy. According to Claire Buchanan, chief commercial officer at self-configuring infrastructure optimise networks (SCION) vendor Bridgeworks, this battle is still ongoing....

Are you sure your data centre is really as secure as you think it is?

(c)iStock.com/bjdlzx

Data centres are only as secure as the connectivity that links them up to a network. They can otherwise be prone to cyber-attacks or information security breaches, which can have catastrophic consequences for any organisations that wish to transmit data and backup data between their own data centres. With network latency being an issue that needs to be addressed, the transmission to and from data centres or to the outside world could increase the risks associated with...

Disaster recovery: Where time matters

(c)iStock.com/ziggymaj

Disasters can strike at any time. They may be caused by human error, cyber-attacks or by natural disasters such as earthquakes, fires, floods and hurricanes. Even so it’s quite tempting to sit back and relax, to not worry about the consequences of these upon one’s business – perhaps for cost reasons, but investments in business continuity are like an insurance policy. It’s not just about disaster recovery because the best way to prevent...

Why virtualisation isn't enough in cloud computing

While it is generally recognised that virtualisation is an important step in the move to cloud computing, as it enables efficient use of the underlying hardware and allows for true scalability,  for virtualisation in order to be truly valuable it really needs to understand the workloads that run on it and offer clear visibility of both the virtual and physical worlds.

On its own, virtualisation does not lend itself to creating sufficient visibility about the multiple applications and services running at...
