As I already said in a previous post, there are a number of questions that show up frequently enough regarding the cloud computing and the switch to cloud. And the decision to migrate or not to cloud solutions hangs often by the answers to those questions.
The first question is „What is the true meaning of the Cloud?”.
As with any major technology transformation, there are many definitions of cloud computing. In very simple terms, cloud computing is a new consumption and delivery model for information technology (IT) and business services that is characterized by: on-demand self-service, location independent resource pooling, rapid horizontal and vertical scaling, pay-per-use. And the exciting impact comes from enabling new service consumption and delivery models that support business model innovation.
The second is „What applications should I move to the cloud and what changes to my network do I have to make to use Cloud?” A wide variety of applications are good candidates to be moved to the cloud. Legacy applications are certainly great candidates for offloading from your internal data centers. Web servers and web applications like SharePoint, .NET, Drupal, Wordpress, Blogspot, Wikis, corporate intranets are all good candidates. As most cloud`experts said, when selecting applications for the cloud you need to be aware of the distance between the data center and the cloud region you’ve selected. According to Forrester Research, the changes to a company network are minimals. Because we taking about an outbound traffic only, nothing inbound. Therefore are no changes to your network configurations.
„How can I implement the Cloud computing security?” is the third question that show up frequently. When an organization decides to move to the cloud, it must first determine its foundational controls which form the backbone of the company’s security principles. Plans must be laid out in order to secure the company’s assets so that when the company subscribes to cloud computing, all the needed security controls must already be in place. Also, the company will have to be workload-focused instead of cloud-focused. When moving to the cloud, the organization must take into consideration each workload, so that it will be able to enforce a security program which is focused on the workload with a possibility to implement non-traditional security measures.
Now, having the answers for the most important questions asked before switching to the cloud, your decision related to adopting or not adopting cloud computing technology can be easily taken.
