As I am a staunch supporter of cloud computing, I have thought about user data retention and their long-term future. Whether we know it or not, we all use cloud storage tools for our data (gmail, Google docs, photos, our company tools, etc.), but, in the end, we don’t have exact information concerning data perenniality behind these innovative storage facilities.The main purpose of cloud computing as a concept is to rent storage space, power and applications. Unlike standard information technology, which is managed in-house, storage space and power are no longer constraints except for… price. That’s the sore spot.To avoid high budgets, companies limit their employees’ storage space, either on their e-mail accounts or on their entire workspace if we refer to DaaS (Desktop as a Service or virtual office). In this respect, as we are instinctively (or usually) rather conservative, we save a part of the cloud information on our physical workstation or on another storage peripheral that would no longer provide all storage guarantees (redundancy, backup, etc.). Here is the starting point of our data vulnerability, as, even if there are solutions for this, as well as good practices to be enforced, however, most of us tend to forget that, and we risk losing all our data when our external storage device crashes, or is stolen!This makes me think that, on the one hand our data are very (sometimes too?) protected, but on the other hand they can be very vulnerable because of the pernicious effect of the cloud. Then, how could we combine small storage space for the “cloud workers” with data perenniality?What about providing lower performance storage services at more convenient prices to take over the data load in cloud applications or in DaaS in case of authorized storage space overflow?————————————————————————————————————————————————————————-For more information, please take a look at Pentalog’s Cloud Computing Offer.
