The Amazon Net Companies (AWS) outage on Monday made world headlines after knocking among the world’s largest websites offline for hours.
For customers, the impacts ranged from the intense – similar to not with the ability to entry very important banking, authorities or work companies – to the not-so-serious, similar to fears of shedding lengthy built-up streaks on Duolingo.
However the outage has additionally reignited the controversy round whether or not nations, together with the UK, are over-dependent on a handful of US tech corporations.
Ought to we fear that a problem occurring on the coronary heart of Amazon’s cloud computing operations in Virginia badly affected UK corporations and companies similar to Lloyds Financial institution and HMRC – and what, if something, can we do about it?
Market dominance
Amazon has embedded itself throughout the very cloth of cloud-based computing, the infrastructure that underpins the supply of the IT methods that are a lot part of all our lives.
The corporate and Microsoft’s cloud companies, Azure, have every cornered someplace between 30 and 40% of the market within the UK and Europe, in keeping with the UK markets regulator, the Competitors and Markets Authority (CMA).
However even that determine would not totally seize how important they’re.
As a result of even when a service itself shouldn’t be hosted by one in every of these two giants – or the UK’s third largest supplier, Google – vital issues it depends upon nonetheless is likely to be.
“A cloud deployment is a sophisticated piece of infrastructure with many parts, some invisible,” mentioned Prof James Davenport, Hebron and Medlock Professor of Data Expertise on the College of Bathtub.
Brent Ellis, principal analyst at market researcher Forrester, mentioned the outage uncovered what he known as the “nested dependency” between in style digital platforms and the array of companies offering the net’s technical underpinnings.
He additionally mentioned it underscored the dangers inherent in that dependency.
“There’s nice enchantment to utilizing tech giants, however assuming they’re too large to fail or inherently resilient is a mistake, with the proof being the present outage and previous ones,” he mentioned.
“It is a characteristic of a extremely concentrated danger the place even small service outages can ripple by means of the worldwide economic system.”
These ripples are what tens of millions of customers felt on Monday.
Economies of scale
So, if counting on a small variety of US corporations has its dangers, why accomplish that many firms do it?
The reply, specialists say, is that inking contracts with family names similar to Amazon, Microsoft or Google additionally has its upsides.
It means an organization would not should pay hefty prices to run its personal servers, and may leverage the ability of so-called hyperscalers to deal with fluctuations in web site site visitors – in addition to typically profit from heightened cyber-security.
Vili Lehdonvirta, professor of know-how coverage at Aalto College in Finland, informed the BBC that the sector, at its core, is “pushed by economies of scale.”
Or, put one other manner, decreasing the present dependence on US tech giants and making a extra “sovereign” infrastructure would include a excessive price ticket.
With the likes of Amazon and Microsoft already embedded in many various features of digital operations, firms trying to migrate elsewhere or diversify could face challenges, mentioned Stephen Kelly of Circata.
“The explosion of enterprise information now saved with a single supplier like AWS makes the eventual value of migrating to completely different distributors prohibitively excessive,” he mentioned.
‘Honest and open competitors’
Nonetheless there’s unease about the established order.
The dominance of some small firms has come to outline a lot of the tech business at massive – from social media to streaming
And within the cloud sector, some consider this will likely imply smaller suppliers could be neglected or ignored.
Nicky Stewart, senior advisor to the Open Cloud Coalition, has joined numerous different specialists in saying Monday’s outage confirmed “the dangers of over-reliance on two dominant cloud suppliers, an outage most of us can have felt indirectly”.
The CMA said in July its investigation into competitors within the UK cloud companies market had discovered it was “not working effectively”.
The regulator advisable it use its personal recently-acquired powers to analyze whether or not to designate Amazon and Microsoft as having “strategic market standing” – which might enable it to demand adjustments to spice up competitors.
Ms Stewart mentioned occasions just like the AWS outage display the necessity for “a extra open, aggressive and interoperable cloud market; one the place no single supplier can deliver a lot of our digital world to a standstill”.
“Honest and open competitors will allow the UK to diversify its cloud workloads, strengthen our nationwide resilience and permit UK challenger cloud suppliers to deliver their expertise and innovation to this over-concentrated and unhealthy market,” she mentioned.
Mr Kelly, in the meantime, mentioned the potential “problem” of diversifying cloud suppliers shouldn’t overshadow the pressing want for IT resilience.
In the end, he mentioned, the answer was political.
“The UK authorities also needs to take the lead in mandating information resilience requirements throughout key industries, together with coverage frameworks that require the usage of two or extra distinct cloud suppliers and promote steady information replication,” he mentioned.
