Disadvantages of cloud storage
- Security threats: Online cloud storage provides secure and efficient data management, but that doesn’t mean cloud vendors are immune to privacy issues, hacks, and security breaches. Entrusting sensitive data to third-party vendors can raise a number of concerns around data confidentiality, Internet file transfers, and the management of internal and external file access. Some of these issues can be avoided with a hosted private cloud service, though private cloud options are often more expensive than public and hybrid cloud services.
- Limited data management: Users who choose a public or hybrid cloud storage service relinquish partial or total control of their data organization to an outside vendor. Legacy on-premise infrastructure may not be fully compatible with certain cloud storage systems, and a complete migration to the cloud is often a complicated process. This is another area in which internal private cloud storage or hosted private cloud storage may make more sense for those looking to retain complete control over the way their data is stored.
- Vendor lock-in: Just as it can be difficult to migrate from on-premise infrastructure to a cloud service, it can be difficult to migrate from one cloud vendor to another. The longer a business utilizes a particular cloud vendor, the more they run the risk of vendor lock indue to contractual stipulations, incompatibilities between vendor systems, and lack of data migration tools and services.
