Three Reasons why Cloud Outages Occur
A single incorrect command can possibly bring down the entire IT infrastructure service, despite strict protocols and systems in place to avoid such unforeseen consequences.
Fremont, CA: Cloud Outage refers to the amount of time when the cloud infrastructure service is unavailable for use. The inaccessibility may also refer to the service's performance inadequacy, as per the agreed SLA metrics. Until the service is fully restored as per the agreed SLA standards, it can be seen as downtime for the end-user.
Cyberattacks such as the Distributed Denial of Service (DDoS) cause data centers to overload with incoming traffic, restricting authorized users from accessing the service through the same networking channels. Despite sufficient security systems in place, hackers manipulate hidden vulnerabilities that either stimulate a protection mechanism that isolates services from legitimate users, leaks data, or shuts down the service altogether.
Software and Technical Issues:
The cloud infrastructure consists of a complex system of hardware and software technology. Anomalies and bugs are likely to occur in enterprise-grade data centers that fuel organizations of all sizes and vertical sizes. These technical problems may be neglected or remain under the radar until they are converted into an actual service incident affecting end-users. If the solution to these issues is not evident or relevant to the instant resolution of problems, the service may remain in a state of emergency.
One of the most common causes of a cloud service shutdown is the unavailability of the electrical energy that powers the data centers. Fundamentally, cloud vendors perform on a massive scale – a single data center can consume 10 to 100 megawatts of power, for which they rely primarily on national grids or power plants managed independently by third parties. This makes the consistent availability of sufficient electricity an issue for data center companies, especially as fast expansion and scalable market demands entail a scalable power source that is otherwise only available in limited quantities.
