Melbourne, Oct 21 (The Conversation) The world's leading cloud computing platform, Amazon Web Services (AWS), recently faced a significant outage, affecting thousands of organizations, including banks, financial software platforms like Xero, and social media channels like Snapchat.
The disruption started at around 6 p.m. AEDT on Monday, originating from a malfunction in an AWS data center located in Northern Virginia, USA. While AWS has addressed the root cause, some internet users are still experiencing service intermittencies. This incident underscores the vulnerabilities associated with heavy reliance on cloud computing—often referred to as "the cloud." There are strategies, however, to mitigate some of these risks.
Renting IT infrastructure
Cloud computing is essentially the on-demand provision of various IT resources such as computing power, database storage, and applications delivered over the internet. In simpler terms, it means renting IT infrastructure rather than owning it.
The concept of cloud computing gained traction during the dot-com boom in the late 1990s when tech companies began delivering software over the internet. As companies like Amazon mastered the art of offering "software as a service" online, they extended the opportunity for others to rent their virtual servers for a fee.
This proposition proved to be lucrative. Cloud computing follows a pay-as-you-go model akin to utility billing, allowing businesses to avoid huge upfront costs associated with purchasing, operating, and managing their own data centers. Consequently, the latest statistics reveal that more than 94 percent of enterprises use some form of cloud-based services.
A market dominated by three companies
The global cloud market is primarily controlled by three giants. AWS holds the largest market share at around 30 percent, followed by Microsoft Azure at approximately 20 percent, and Google Cloud Platform at about 13 percent.
All three have experienced recent outages, impacting digital service platforms significantly. In 2024, Microsoft Azure suffered extensive operational failures globally due to an issue with third-party software. Similarly, earlier this year, the Google Cloud Platform encountered a major outage caused by an internal misconfiguration.
Profound risks
The heavy global dependence on just a few major providers—AWS, Azure, and Google Cloud—creates substantial risks for businesses and everyday users alike. First, the concentration poses a single point of failure. As demonstrated by the latest AWS event, a simple error in one core system can rapidly cascade, disabling large portions of the internet.
Moreover, these providers often enforce vendor lock-in, making it prohibitively challenging and costly for companies to switch platforms due to complex data architectures and high fees for transferring large data volumes out of the cloud (known as data egress costs). This entraps customers, binding them to a single vendor's terms.
Additionally, the dominance of US-based cloud providers introduces geopolitical and regulatory challenges. The data housed within these massive systems is subject to US legal demands, complicating compliance with international data sovereignty laws, such as Australia's Privacy Act. Furthermore, these firms possess the power to censor or restrict access to services, influencing how companies operate.
The best current practice to mitigate these risks is adopting a multi-cloud strategy, enabling businesses to decentralize by running critical applications across multiple providers to prevent a single point of failure. This can be complemented by "edge computing," where data storage and processing move away from central data centers to smaller, distributed nodes (like local servers) that businesses directly control.
The synergy of edge computing and a multi-cloud approach enhances resilience, boosts performance, and helps firms comply with stringent data regulations while avoiding over-reliance on any single entity. As the adage goes, don't put all your eggs in one basket. (The Conversation) GRS GRS
