What cloud outages tell us about putting your eggs in one basket

In July, what seemed for illustration an innocuous package update from a cybersecurity vendor, CrowdStrike, caused millions of Windows-based machines crossed nan globe to crash. This wasn’t nan first awesome tech outage, and nor will it beryllium nan last. In fact, outages hap regularly crossed nan tech landscape, for a immense assortment of reasons. In nan past six months alone, Google Cloud Platform, AWS and Microsoft Azure person each suffered outages. The fallout tin beryllium terrible – planes are grounded, infirmary patients are near waiting for treatment, rate fleetingly becomes king again arsenic paper payments can’t beryllium processed.

Outages are besides costly for organizations. It’s estimated that nan downtime and consequent activity to hole machines successful nan aftermath of nan CrowdStrike outage costs $5.4 cardinal to Fortune 500 companies alone. They’ll drawback nan oculus of regulators too. Landmark EU regulations specified arsenic nan Digital Operational Resilience Act (DORA) and nan NIS2 Directive – some of which person an indirect effect connected UK organizations and attraction connected consequence and resilience – are coming into effect wrong nan adjacent six months.

This spate of outages should sound nan siren for organizations to commencement reasoning astir really resilient they are to specified events and nan risks of relying connected a mini excavation of vendors, peculiarly cloud providers, which person go ingrained successful business strategy.

Cloud consolidation conundrum

Globally, it’s estimated that nan 3 cloud hyperscalers – AWS, Microsoft Azure and Google Cloud Platform – person a marketplace stock of 66%. This consolidation of nan unreality marketplace has upped nan stakes – 1 faulty update aliases hyperscaler outage would person a profound effect connected businesses globally.

Thankfully, these unreality giants are comparatively resilient and full-scale outages seldom – if ever – occur. But caller history shows america that it's reasonably communal for astatine slightest immoderate systems to beryllium taken offline. This highlights why a multi unreality strategy – whereby organizations shop data pinch much than 1 hyperscaler – is an absolute necessity for building resilience. Leaving each your eggs successful 1 handbasket is risky, because if nan handbasket breaks, organizations' captious services tin beryllium taken offline.

But a multi unreality strategy comes pinch its ain challenges. Firstly, each of nan hyperscalers’ platforms has its ain nuances. It’s not imaginable to simply assistance and displacement data, workloads and applications from 1 unreality to another. Subtle changes whitethorn request to beryllium made to information and workloads, and applications will person to beryllium refactored to suit their caller environment. This takes time, resources and master skills.

Multi unreality besides creates information siloes. For example, a heavy regulated statement successful nan finance manufacture whitethorn utilize backstage unreality to support power complete information for compliance. If they besides person information successful astatine slightest 2 nationalist clouds, they’ll person to necktie together 3 disparate environments, making it very difficult to thrust worth from their data.

Finally, multi unreality decreases visibility complete data. With information sitting crossed aggregate environments, it’s overmuch much difficult to cognize wherever it’s located, who has entree to it, really it’s being utilized and what it has been utilized for successful nan past. This amplifies challenges astir governance and reporting arsenic a azygous entity. But possibly much profoundly, arsenic organizations commencement to deploy generative AI usage cases successful production, visibility is becoming perfectly captious to success. For AI to beryllium genuinely effective, it must person entree to a complete group of data, different organizations tally nan consequence of hallucinations and AI giving penetration that lacks nan basal business context.

Laying nan foundations for resilience

So, connected nan 1 manus a multi unreality strategy helps organisations to build resilience, hardening them against nan anticipation of an outage aliases disruption to a awesome unreality provider. But connected nan other, it creates analyzable challenges – fragmenting information and draining resources.

This is why deploying a modern information architecture built astir a unified information level is simply a captious measurement erstwhile looking to diversify unreality providers. It provides a furniture of abstraction crossed unreality environments, which gives organizations nan elasticity to move information betwixt clouds without nan request for timely, resource-intensive refactoring. This enables them to thrust worth from data, nary matter wherever it resides.

Organizations must study from nan mistakes of nan caller past and extremity their reliance connected conscionable a mini excavation of providers. But they request to laic nan foundations for success, ensuring that immoderate efforts to build unreality resilience don’t inhibit innovation.
