A current information centre outage in Sydney affected a number of cloud service suppliers and companies, together with Financial institution of Queensland and Jetstar. After this and different incidents, cloud clients may nicely ask if the identical factor may occur to them — and how you can mitigate it earlier than it occurs.
Can the dangers of bodily information centres be managed?
TechRepublic spoke with Nam Je Cho, director of options structure for AWS Australia and New Zealand, and Man Danskine, managing director at information centre supplier Equinix Australia, who’re each in field seats to witness the area’s embrace of the cloud.
Cho and Danskine have advisable a variety of methods, together with embracing geographic range, making certain there are built-in redundancies, looking for out information centre administration finest practices and contemplating the chance advantages of hybrid multicloud infrastructure.

Australia’s information centre outages present some dangers do stay
Australian organisations had been reminded that cloud computing dangers do exist in August 2023. A lightning strike on electrical infrastructure 18 miles from a Sydney information centre prompted a utility voltage sag, tripping a subset of the power’s cooling system chiller items offline.
Azure, Oracle and NetSuite hit by Sydney information centre outage
As affected cloud service supplier Microsoft Azure reported in a post-incident report, whereas technicians had been working to repair the issue, temperatures within the information centre elevated to ranges above operational thresholds. A subset of compute and storage scale items then needed to be powered all the way down to decrease temperatures and stop {hardware} injury.
The incident impacted cloud clients, starting round 10:30 UTC and lasting till 22:40 UTC. For a few of this time, Financial institution of Queensland clients skilled hassle with the financial institution’s app, and banking transactions weren’t being mirrored accurately in buyer accounts. Jetstar clients, in the meantime, had hassle logging in, managing bookings and checking in for flights.

Azure was not the one service impacted. Because it was a shared information centre, Oracle Cloud and NetSuite providers had been additionally impacted by outages.
Outages like Google’s in Melbourne in 2021 enhance resilience focus
There are different information centre outages on the minds of native cloud clients. Solely a month or so after the launch of the model new area in Melbourne in 2021, Google Cloud Providers in australia-southeast2 went down for 1 hour and half-hour because of transient voltage points.
In a assertion on the incident on the time, Google stated “the foundation reason for the difficulty was transient voltage on the feeder to the community gear, inflicting the gear to reboot. In an effort to mitigate the difficulty, visitors inside the australia-southeast2 area was redirected quickly.”
Forrester’s current State of Cloud in Australia and New Zealand report urged incidents like this outage, in addition to environmental uncertainties, had been encouraging organisations to contemplate revisiting their danger mitigation methods.
“Between the worldwide pandemic, cloud outages in 2021 such because the Google outage in Melbourne, fires and floods in Australia and earthquakes in New Zealand, enterprises are prioritising resilience,” Forrester reported.
Forrester stated danger mitigation could embrace “constructing larger danger consciousness, leveraging a number of AZs (availability zones) for high-priority workloads, mitigating provider danger by way of multi-cloud talent units or scenario-building in opposition to potential dangers.”
Belief in cloud remains to be driving information centre growth
AWS providers a whole lot of 1000’s of companies throughout Australia and New Zealand, together with Atlassian, NAB, and public sector businesses just like the Australian Bureau of Statistics and Western Australia’s Division of Schooling. Equinix, likewise, is trusted by clients in vital industries, together with healthcare, monetary providers and authorities.
This calibre of buyer must have cloud service across the clock with out disruption.
Equinix Australia’s Danskine stated organisations perceive that information centres and the cloud are taking part in a foundational position in supporting their companies. Danskine added that the scalability, reliability and cost-efficiency of cloud applied sciences and infrastructure are what allow organisations to function successfully in an more and more digital financial system.
“Strong digital infrastructure is key,” Danskine stated. “It permits organisations to attach customers, clients and workers, enhances information safety and permits them to adapt to evolving market calls for.”
This demand is propelling Equinix’s progress. It has 51 information centres within the APAC area, together with 22 in Australia, positioned in Sydney, Melbourne, Brisbane, Canberra, Perth and Adelaide.
It is usually investing over AU $1 billion (US $645 million) in 13 tasks that can see new information centres in-built Australia, India, Japan and Korea in addition to expanded services in Indonesia and Malaysia.
“We’re at all times in search of the precise alternative to broaden, in step with buyer and market demand, to make sure we are able to finest help present and future necessities,” Danskine stated.
In the meantime, AWS is investing AU $13.2 billion (US $8.44 billion) into infrastructure from 2023 to 2027 throughout Australia, and is constructing a brand new area in Auckland with three availability zones.
Investments like these of AWS and Equinix are underpinning what Forrester has known as “a brand new scale of public cloud utilization” in Australasia. Organisations at the moment migrating to the cloud anticipate a median of 46% of workloads to be within the cloud inside the subsequent two years.
As digital transformation continues to be a excessive precedence, Danskine stated that companies are trusting information centres and the cloud to supply the infrastructure wanted to gas innovation, help excessive ranges of availability and “drive progress in a data-driven world”.
Suppliers are designing the cloud to mitigate information centre danger
Regardless of sturdy ranges of belief, Danskine stated the market was not danger free.
“After the pandemic, many organisations are working with fewer employees onsite, so the potential of a system failure, even with automated distant monitoring and preventive upkeep, has elevated,” Danskine stated.
One technique to fight this danger is for organisations to make sure they’ve energy redundancy to decrease the influence of a system failure.

“At Equinix, we offer totally redundant electrical and mechanical infrastructure as commonplace to our international information centre clients,” Danskine stated.
AWS focuses on availability zones to mitigate danger of downtime
Danger mitigation is a central design characteristic for cloud and information centre suppliers. For instance, AWS, like different cloud suppliers, affords a number of availability zones inside all of its areas. This implies an software will be partitioned throughout completely different geographies.
“AZ’s are bodily separated by a significant distance, many kilometres, though all are inside 100 kilometres (60 miles) of one another,” AWS’s Cho stated. “Every AZ has unbiased energy, cooling and bodily safety and is linked through redundant, ultra-low-latency networks.
“If an software is partitioned throughout AZs, corporations are higher remoted and shielded from points resembling energy outages, pure climate occasions and extra.”
Multi-AZ managed providers just like the Amazon Relational Database Service and Amazon Elastic Kubernetes Service enable its clients to pick which AZs they deploy throughout.
“If there’s an infrastructure occasion in a single AZ, there’s managed and computerized failover to a second AZ and failback as acceptable, with little to no service disruptions,” Cho stated. “Our clients are working mission-critical workloads by deploying workloads with multi-AZs and/or multi-regions architectures to attain excessive availability.”
Equinix looking for continuous enchancment in information centre administration
Equinix is continuous to discover methods of accelerating the operational integrity and security of its information centres (Determine A). One instance is that vital upkeep at all times takes place with a minimal of two certified engineers current to double-check one another’s work.
Determine A
When clients select to make use of its software-defined interconnection platform, Equinix Material, to connect with their cloud, SaaS and community suppliers, Danskine stated the corporate at all times recommends configuring two bodily ports.
“Firms can depend on these for added resiliency when connecting to 1000’s of worldwide finish factors or their very own IT infrastructure on Platform Equinix,” Danskine stated. “Firms can create interconnected enterprise continuity and catastrophe restoration situations that meet their wants.”
What can companies do to maximise their cloud resilience?
Cloud and information centre uptimes are near 100%. Equinix has a worldwide uptime of >99.9999% throughout 250 information centres, whereas AWS permits 99.999% availability. However there are methods clients can mitigate the chance of an information centre outage exterior of relying on their suppliers’ uptime.
Use geographical range
Geographical range is a foundational design characteristic of recent cloud providers and ought to be thought-about essential for all vital infrastructure. Just like the a number of availability zones on provide inside AWS areas, this unfold of geographic danger could possibly be through a number of information centres, mapping an software to a number of cloud areas or deploying the workload through containers.
Hunt down community redundancy
A redundant community can help full operations throughout a service disruption and allow in-flight upkeep. Equinix stated companies ought to guarantee redundancies in particular person community parts complement one another and the general design, in order that if an outage does happen, it will trigger minimal influence whereas restoration efforts are underway.
Guarantee common planning and testing
Equinix argues common testing is vital. It exams vital techniques each two weeks below most load and performs an annual “darkish website take a look at,” the place it deliberately disconnects websites from primary energy to make sure backup techniques come up and carry out as anticipated. Forrester additionally recommends revisiting the chance and continuity parts of cloud methods.
Undertake a hybrid multicloud technique
More and more, organisations are pursuing cloud-agnostic digital infrastructure to attain benefits like innovation, cost-efficiency and resilience. Pairing a number of clouds with cloud-adjacent on-premises environments can present companies with essential safety and enterprise continuity advantages, constructing in additional resilience for organisations.

Utilise a managed service
AWS affords quite a lot of managed providers that enable organisations to function inside and throughout the area without having to architect for multi-AZ traits themselves. With AWS caring for this by default, if there’s a problem inside a specific AZ, it will likely be dealt with on the shopper’s behalf as a part of a shared accountability mannequin.
The way forward for cloud to maintain clients agile and resilient
Current information centre outages is not going to gradual cloud methods. Danskine argues hybrid multicloud is turning into the structure of alternative for a lot of as a result of it’s a versatile infrastructure technique. And in accordance with the fifth annual Nutanix Enterprise Cloud Index, respondents in Australia anticipate to extend their use of this mannequin greater than fivefold to 43% penetration by 2026.
“This strategy offers the pliability to decide on between private and non-private clouds, optimising efficiency and cost-efficiency,” Danskine stated. “It additionally enhances resilience by way of redundancy and catastrophe restoration capabilities and permits compliance with regulatory necessities within the host nation, making certain information safety and sovereignty.”
Nam Je Cho from AWS stated there isn’t any doubt the area is “in the course of a tectonic shift to the cloud. The primary motive that our clients are shifting and innovating on the cloud is the agility and velocity with which they’ll change their buyer expertise.”
