While the cloud offers many benefits, firms may hold back from pursuing this technology due to the “noisy neighbor” problem. Noisy neighbors within a cloud infrastructure are similar to noisy neighbors within an apartment building; just as the noise from the person living next door can impact your own lifestyle (eg, lack of sleep if a neighbor is blasting music late at night), the negative behavior of other tenants within a cloud infrastructure (eg, dominating bandwidth) can impact a firm’s performance from a systems perspective.
In the cloud realm, the term “noisy neighbors” is defined as a cloud computing co-tenant that dominates the bandwidth, disk I/O, and CPU within a multitenant cloud infrastructure, thus negatively impacting the other cloud co-tenants and causing cloud network performance to diminish. Typically, the noisy neighbor issue has to do with storage.
In a multi-tenant environment, a single instance of an application is run to provide network access to multiple firms, with individual data secluded and completely invisible to other tenants. However, the noisy neighbor issue arises when there are minimal limitations placed on how cloud resources can be utilized among tenants. The hypervisor used to virtualize the service makes each VM behave as if it has exclusive access to the physical server hardware. And fears about performance issues in the cloud can prevent firms from moving their critical applications to this environment.
But just because a firm has moved to a cloud infrastructure doesn’t mean that they need to be plagued by noisy neighbor issues. There are a variety of methods for mitigation. When considering a cloud environment, vet your provider to ensure that they have taken appropriate steps to minimize performance inefficiencies in the cloud. Outside of ensuring that you have the fastest connection to the cloud, all flash storage arrays are a next generation method that ensure the highest level of services. All flash storage array solutions allow for reduced power consumption and on-demand scalability, enabling seamless growth and high performance for high-load applications such as large and sensitive databases. On-demand storage scalability minimizes noisy neighbor issues having to do with storage. In addition, storage based quality of service built into the cloud architecture provides defined service levels that eliminate performance issues.
