In challenging economic times, organisations naturally look to cut back or defer non-essential investment. IT spend has traditionally been one of the areas businesses look to first when the need arises to cut budgets or delay projects, sometimes creating a ‘good enough IT’ mindset, where any IT asset that is doing the job reasonably effectively today is maintained beyond the last responsible moment for replacement.
This strategy has always been risky. Today’s volatile and challenging business environment, where digital and IT is at the heart of most businesses, and the stakes around IT failures and breaches get higher every day, makes it even more questionable.
This blog considers the specific cost and risk implications of a ‘good enough’ approach to IT infrastructure – servers and storage - and why organisations which are increasingly reliant on digital capability need to protect their investment in keeping it current.
Operational cost impacts
The cost of migrating to newer technology is offset by the overhead of maintaining legacy. Legacy support can take up 60-80% of total IT spend in an organisation. Vendors understandably charge a premium for continuing to support technology that is no longer current, to cover the costs they incur in maintaining a wide spread of products and versions, and in finding increasingly scarce legacy skills.
While older infrastructure is often perceived as very stable – ‘it hasn’t failed in the last ten years, so why replace it?’ – there is a tipping point where failures become more and more likely the older the infrastructure gets. When it does fail, it can be very costly and slow to fix because the resources and knowledge required are scarce.
Performance can degrade as infrastructure ages, increasing cost per IOPS and incurring costs to upgrade or augment the existing estate.
Business cost and risk
No CIO wants to tell the business that they don’t know when that critical systems outage will be fixed, because the vendor just withdrew support for that product. The direct business costs and reputational damage of a single legacy IT failure can be substantial, potentially eclipsing the investment in new IT that could have averted it.
Older infrastructure poses a security risk that increases rapidly as it ages. The 2017 Wannacry ransomware attack is estimated to have cost the UK National Health Service (NHS) around £92 million, and led to 19,000 healthcare appointments being cancelled in one week. The vulnerability that allowed the ransomware in was in an old, unpatched version of Windows which was presumably deemed ‘good enough’ in the context of a service where investment was at a premium.
Business competitiveness increasingly depends on the ability to maximise digital capability, using the power of technology to respond rapidly and effectively to new opportunities and shifts in the market.
A business running significant levels of legacy IT has an inherent competitive disadvantage compared with one that has successfully harnessed the flexibility and agility of modern technologies and the cloud.
A powerful driver for the success of digital disruptors versus heritage businesses in areas such as eCommerce and transportation has been their ability to create these capabilities rapidly from day one, while their established competitors grapple with adapting their legacy estates.
In considering whether to sweat that IT asset for one more investment cycle, it’s critical to consider all these potentially hidden costs and risks of ‘good enough IT’.

How to Continue Transforming During a Recession
With the current economic slowdown, it looks like another recession could be on the cards in 2023. This usually heralds a period of consolidation within IT and the closing of the purse strings with regards to planned investments. In previous decades this was standard practice, but now that we’re in a digital age, many businesses can’t afford to slow down their digital transformations if they want to survive.

Reducing Digital Waste
Sustainability is imperative to all our futures and is directly impacted by every device we use that consumes power. This includes the on-premises and cloud infrastructures that power our digital work lives. To be as sustainable as possible we need to ensure that we are consuming the least amount of infrastructure to host our workloads and services, without impacting their availability, performance or governance.

Is it time for Business Process Management software to join the enterprise platform big league?
Business Process Management (BPM) has had something of a chequered history in the enterprise space. While Lean, Six Sigma and other quality methodologies have led some organisations to embrace formal process management as part of their DNA, others have not achieved the same level of traction.

Breaking down the great global data challenge
There are plenty of statistics around the staggering amount of data being created and consumed globally every day. 2.5 quintillion (million million million) bytes created daily by internet users, a 5000% increase in data interactions between 2010 and 2020, and so on.

Why data storage trends are about more than just technology
There are plenty of informative and valuable articles on the web about trends in data storage technology, discussing everything from reducing last byte latency to the wonders of consumption-based pricing. Data and storage are hot topics, unsurprisingly in an age where, as Mckinsey puts it, ‘“digital” and “data” have become the talk of the town.’

Is it time to stop talking about the death of tape storage?
Heritage technologies - mainframe, Unix and magnetic tape in particular – have long been a rich source for the ‘is x technology dead?’ debate. Technical pundits fill the web with head scratching over why they haven’t disappeared, or defences for their survival.

Where next for Virtualisation?
In its broadest sense, virtualisation can be seen as the progressive freeing up of any computing function – compute, storage, network – from the constraints of its physical infrastructure. So far, virtualisation has been a continuous evolution, from the first virtual machines (VMs) to the world of hybrid cloud, and there is no sign yet of this evolution losing momentum.
