Cloud computing is the latest breakthrough in the computer revolution and everybody is talking about it. Though most of them have no idea about underlying features of cloud computing, people are using it and finding it far better than conventional methods. What is cloud computing? Cloud concept can be best understood by assuming it as a pool of resources from which people can share and borrow resources. It is like power grid that supplies electricity to your homes and offices. Cloud computing is like a grid of services like software and data where a user can get access to desired service without actually owning it. Although companies which offer cloud computing claim clouds to be completely secure, there are some loopholes in cloud security. If these loopholes are filled cloud sharing can be beneficial in many ways. Benefits of cloud computing • Cost efficient: A cloud is a pool of resources and a user can use the desired information it without having to buy it at high costs. An application that would otherwise cost very high in setting up dedicated servers can be reduced considerably by sharing resources. • Fast speed: Information in clouds is stored at different locations so you can access it from your nearby cloud server. This increases the speed many folds and hence reduces time taken considerably. Security issues Cloud is the storage house of huge amounts of data; it is a work place where you can do computing without being physically present near it. A large number of people can access the softwares and data present in a cloud making it vulnerable to hackers. Hackers can get access to highly confidential information thus making it unsafe. Security issues related to cloud can be broadly divided into two categories. • Security issues faced by cloud computing providers • Security issues faced by Cloud computing customers In order to maintain security service providers take care of following things. • Data protection: cloud providers ensure that there is no data leakage and the data from different customers are stored a different locations. They also keep the data safe from any third party which can be in the form of hackers. • Identity management: Service providers make provisions for their customers to have control on the traffic over their share of information. It helps in ensuring controlled and limited access to intended users. • Application software security: the providers make sure that the softwares they are offering for use are not corrupt and are free from hacking. Cloud computing is a boon to big and small enterprises as well as individual users. A number of businesses are run using cloud concept. This has enabled companies to have an efficient and cost effective pool of all the resources they can want. A new field of study has emerged with cloud computing and it is cloud security training. It covers issues related to cloud hacking and the ways to counter these problems. People who have done security training are very much in demand and have good future prospects. Cloud computing is a new concept and so are the challenges related to cloud security. For further reference please visit Trainace.com/courses/cloud-security/.
