Tiered data centers allow for hierarchical data storage, where the files and data for applications that users access most frequently, or that require very high performance, can live in one tier, while data that is not accessed as frequently can live in a different tier. Network and application security software can provide essential virtual security measures.ĭata centers can have different levels of security, latency, and resiliency-these levels are known as tiers. A data center must be protected from theft with physical security measures such as locks, video surveillance, and restricted access. Both physical and virtual security measures are necessary to ensure that a data center stays secure and that businesses are not vulnerable to a data breach. A breach where sensitive customer or company data becomes exposed can cost hundreds of thousands of dollars and, in worst-case scenarios, destroy a company’s brand and business.
