Top Five Challenges Of Cloud Computing

Top Five Challenges Of Cloud Computing

Companies are increasingly aware of the business value that cloud computing brings and are taking steps towards transition to the cloud. A smooth transition entails a thorough understanding of the benefits as well as challenges involved. Like any new technology, the adoption of cloud computing is not free from issues. Some of the most important challenges are as follows.

1. Security and Privacy

The main challenge to cloud computing is how it addresses the security and privacy concerns of businesses thinking of adopting it. The fact that the valuable enterprise data will reside outside the corporate firewall raises serious concerns. Hacking and various attacks to cloud infrastructure would affect multiple clients even if only one site is attacked. These risks can be mitigated by using security applications, encrypted file systems, data loss software, and buying security hardware to track unusual behavior across servers.

2. Service Delivery and Billing

It is difficult to assess the costs involved due to the on-demand nature of the services. Budgeting and assessment of the cost will be very difficult unless the provider has some good and comparable benchmarks to offer. The service-level agreements (SLAs) of the provider are not adequate to guarantee the availability and scalability. Businesses will be reluctant to switch to cloud without a strong service quality guarantee.

3. Interoperability and Portability

Businesses should have the leverage of migrating in and out of the cloud and switching providers whenever they want, and there should be no lock-in period. Cloud computing services should have the capability to integrate smoothly with the on-premise IT.

4. Reliability and Availability

Cloud providers still lack round-the-clock service; this results in frequent outages. It is important to monitor the service being provided using internal or third-party tools. It is vital to have plans to supervise usage, SLAs, performance, robustness, and business dependency of these services.

5. Performance and Bandwidth Cost

Businesses can save money on hardware but they have to spend more for the bandwidth. This can be a low cost for smaller applications but can be significantly high for the data-intensive applications. Delivering intensive and complex data over the network requires sufficient bandwidth. Because of this, many businesses are waiting for a reduced cost before switching to the cloud.

All these challenges should not be considered as road blocks in the pursuit of cloud computing. It is rather important to give serious consideration to these issues and the possible ways out before adopting the technology.

  1. Challenges are always there for us to surpass, in the case of adopting cloud computing system it is but important to think of the positive things that it brings to our company and be prepared to face such mentioned challenges above.  Because despite of all of this, cloud remains to be very reasonable, effective and efficient.

  2. I would put #2 as #1 and #5 and #2. Billing is a huge technical issue that can consume a great deal of resources to respond to. Performance is a BIG issue as far as server environment are concerned. Desktops can run slow without end users really noticing a difference from their current desktops. Servers on the other hand need speed and cloud environments don’t fair well here unless you have huge budgets. Bandwidth not such a huge issue unless the cloud provider makes it one. 
     
    #1 issue of security I see more a matter of managing process implementation. It just takes some well thought out processes to deal with all of that. This should be around #3 I would say. Not to suggest security should take a back seat, but in this breakdown of what challenges cloud has.. this is where that challenge belongs in my opinion if we are listing based on the degree of difficulty in addressing the challenges.
