Cloud Computing Disadvantages

Some major obstacles to cloud computing include:

Inconsistent Results Are Possible

In a cloud computing setup, your application shares the server's resources with those of other companies. Your tenant's greedy actions or a denial-of-service (DDOS) assault could degrade the efficiency of the shared resource.

Technical Issues

Whenever you rely on cloud computing, you risk experiencing an outage or other technical difficulties. Unfortunately, despite rigorous upkeep procedures, even the most reputable cloud service providers are not immune to this problem.

Perilous Cloud-Based Security Measures

Another negative aspect of using cloud computing services is the potential for security breaches. A business must be aware of the risks involved in adopting cloud technology before handing over all of its sensitive data to a third-party provider of cloud computing services. Hackers could access such details.

Downtime

While working on the cloud, it is important to think about potential downtime. This is because power outages, poor network connections, service maintenance, etc., could affect your cloud service provider.

Possibility of Accessing the Internet

While cloud computing relies heavily on the Internet, having reliable Internet access is crucial. If you want to use the cloud, you'll need constant access to the internet. In addition, you cannot access cloud-based information by any other means.

Reduced Bandwidth

Many cloud storage providers often cap bandwidth use. So, if your company exceeds the allotted amount, the overage fees could be quite high.

Lack of Support

Customers of cloud computing services are often left unsupported by their providers. In addition, they prefer that you rely on frequently asked questions and online help, which can be time-consuming for non-technical users.
