How SD-WAN can help in meeting increasing cloud-based demands

The traditional corporate WAN (wide area network) architecture became prolific in the client/server architecture era. We designed and built WANs to largely support branch-to-datacentre.  On paper, these often looked like Clouds, but they are in effect hub and spoke networks – the hub being the data centre.  This worked reasonably well when most of our applications were hosted in one or two datacentres, and access to the Internet was centralised and only available through the Data centre...

SD-WAN: It’s time to become the master of your network

He-Man may have been a master of the universe, but us mere mortals may have to set our goals slightly lower. For many network managers, the network is their own mini universe, but unfortunately, they often don’t have the control or visibility over it that they would like.

Software-defined WAN (SD-WAN) has been identified by some as the solution to this problem, solving businesses’ digital transformation and legacy infrastructure woes. But it is important that this, like any hyped B2B technology,...

How to leverage cloud architectures for high availability

Cloud architectures are used broadly nowadays; the cloud is a plethora of amazing alternatives in terms of services and solutions. However, with great power comes great responsibility, and the cloud presents itself as a place where failure can and eventually will occur. Thus, consequently, it will spread upon the entire architecture fast, possibly causing massive outages that can leave a business on its knees.

Okay, that’s not an overly optimistic scenario – more likely the opposite – but...

Exploring cloud APIs – the unnoticed side of cloud computing

Nowadays, it is increasingly easier to lose one’s self in dashboards, visualisation tools, nice graphics, and all sorts of button-like approaches to cloud computing. Since the last decade, UX work has improved tenfold; nevertheless, there is a side that usually goes unnoticed unless extremely necessary. That side belongs to application user interfaces (APIs).

An API constitutes a set of objects, methods and functions that allows the user to build scripts, or even big applications, to make certain things...

Google Cloud launches sole-tenant nodes for improved compliance and utilisation

Google Cloud has announced the launch of sole-tenant nodes on Google Compute Engine – helping customers in various industries around compliance in the process.

The new service, which is currently in beta availability, gives customers ownership of all VMs, hypervisor and host hardware, going against the traditional cloud use case of multi-tenant architecture and shared resources.

“Normally, VM instances run on physical hosts that may be shared by many customers,” explained Google’s Manish Dalwadi and...

Organisations need ‘reality check’ on cloud costs, research advocates

How do you balance your cloud and on-premises budget – and how do you get the most out of it? It has long been a problem for organisations once they decide they want to move their systems to the cloud – and according to new research from SoftwareONE, companies continue to suffer from high costs and low visibility.

The study, which polled 300 C-level and IT decision makers in North America, had some interesting data points alongside some less surprising results. More than half (53%) of those polled...

Running extreme workloads in the cloud: A guide

As any IT professional knows, running large and resource intensive workloads in the cloud is extremely difficult. The cloud is often billed as a panacea, but the truth is that for most organisations, architecting large workloads in the cloud is a heroic endeavour – one that must be executed with exact precision. There is no margin for error, and one small misstep can result in nightmares for CIOs.

According to the Forrester study, "Cloud...

The top five in-demand cloud skills for 2018

As businesses of every size push forward with cloud projects in 2018, the demand for cloud skills is accelerating. Public cloud adoption is expected to climb significantly and the IDC predict spending will reach £197 billion in just three years.

But as cutting-edge technologies, like machine learning, continue to reshape the job market the skills gap looms large across the industry. With over 350,000 specialists needed to help fill cloud roles there’s clearly a massive opportunity for...

How to botch a cloud migration in three easy steps – and how to remedy it

Today, the cloud is where everyone wants to be; there is no place like it, and nothing makes your clients happier. Okay, that may be a bit of a stretch – but it’s also fair to say that not everyone can dive into the cloud with their current architecture. Many times, it takes a complete re-engineering process in order to carry a company – or even a simple product – into any cloud.

Here are three areas to think about to ensure you do not carry out a disastrous cloud migration.

Rush it and think...

How cloud scalability is seducing the financial sector

The financial sector, while forging ahead in other areas of digital transformation, has been relatively slow to adopt the cloud and there has been good reason for it: banks have to deal with highly sensitive data and sharing data storage and compute resources with others could not even be envisaged, let alone adopted.

However, just under two years ago, the Financial Conduct Authority (FCA) published a new guidance for firms outsourcing to the...

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 when...

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...
