Some CEO’s and business executives still feel that cloud computing has too many shortcomings. They want to hear about cloud, but they don’t believe in its use. The good thing is that cloud computing has proven its value over time. However, the argument around security and privacy issues in the cloud still comes up often.
Clearly, there are myths that cloud computing is inherently less secure than traditional approaches. The fear is largely due to the fact that the approach itself feels insecure, with your data stored on servers and systems you don’t own or control.
However, control does not mean security. We’ve discovered over the years through diverse research reports and experience that the physical location of your data matters less than the means of access. This is the case for both cloud-based systems and traditional enterprise computing. Moreover, those who build cloud-based platforms for enterprises typically focus more on security and governance than those who build systems that will exist inside firewalls.
Despite the paradigm shift to cloud computing, there are still many businesses that are uncomfortable with the idea of a cloud-based infrastructure. This is understandable, At different times we have heard stories about a data breach. In a report published by KPMG, 30% of global senior executives said they have concerns related to the loss of data and privacy, while 26% are concerned with general security risks. Still, it’s hard to deny the benefits of cloud computing.
From cost savings and freedom from hardware constraints to agility and always-current functionality, it’s no wonder that enterprise cloud adoption is on the rise. Yet the question of security continues to be debated. Is it actually safer to entrust your mission-critical data off-premise?
Evaluation of Both Cloud and On-Premise Security
Onsite & Offsite Argument
Some people are of the school of thought that if a company maintains a traditional in-house data center— replete with physical servers, chassis racks, and cooling fans—its IT team has complete control over the data. If an administrator chooses, he or she can keep data from ever leaving the server room. On the other hand in the cloud, security breaches due to unauthorised physical access to a cloud host’s data centres are incredibly rare. The most costly breaches come from within a company’s own firewalls, often from employees, Cloud hosting companies protect customers and alert them immediately about any disturbance. Plus, secure servers hosted in a variety of locations safeguard data better than the risks of a single location.
Some business and IT executives also believed that servers that are physically accessible are better protected from viruses. To them, new security threats are not a large concern when your data centre is housed on-site. The application of new security patches and software updates is completely under the control of your local IT staff, who can verify that virus signatures are kept up-to-date. With Cloud service providers can rapidly deploy a fully-tested virus response to all customers—without your staff’s help. A cloud provider that hosts hundreds of customers offers fast, thorough protection from emerging threats that you would never be able to feasibly manage on your own. Because the cloud host takes care of the time-consuming, tedious task of ensuring that virus signatures are up-to-date and security patches have been applied, your IT staff can focus on more profit-driven activities.
Lastly, there is an argument that on-premise data centres are more reliable because people can resolve all issues themselves. By owning and maintaining your own servers in your company’s own buildings, you can better ensure system uptime, which depends entirely on your maintenance. Your team can perform system checks at any time. If servers are farmed out to a third party, there may be a long queue if you ever need support. While for Cloud systems can better guarantee uptime because they experience fewer service disruptions and have 24/7/365 monitoring.
I want to ask you , for you, what do you think works best the Cloud approach or the Traditional on-premise.
