Many organizations were earlier having their built-in robust data centers, while migration to Cloud has now become an everyday affair as more and more enterprises are venturing into this cloud computing land as compare to traditional IT infrastructure models and opting for their securer platforms.
In traditional IT infrastructure, data centers usually consist of many hardware pieces including desktop machines connected to a particular networks via remote servers. These servers are usually installed on premises, and provide all users, who are using that hardware, an access to their business data as well as applications. Purchase of extra hardware is needed and it is also mandatory to upgrade for scaling up data storage along with additional services for supporting increased number of users. Regular software upgrades are also mandatory and constant hardware additions are always required with these traditional IT models to make systems fail safe in cases of hardware failures; making all this a very costly affair.
Considering the always-increasing costs with traditional IT models, cloud computing seems to be a far more cost-effective option. Also, with this virtual hosting solution, all the software, servers as well as networks are hosted off premises, in cloud; rather than being accessible through physical hardware, as in the traditional models. So the costs of purchasing physical hardware and servers in-house are minimized as data storage space can be rented from cloud providers, which is much more cost-effective option.
In cloud computing, data is saved externally, which seems less secure. Also, with free access to data by anyone anywhere, wherever net connection is available, again causes data leakage threats. With traditional models on the other hand, business owners are only responsible for the data protection of their organizational data, but at the end of the day, that’s not scalable and cost-efficient. So, cloud is a better option, if the only aspect of cloud security is taken care of by enterprises, which is possible to deploy CASB solutions, which go hand-in-hand with cloud providers. Thus, CASB solutions hold a great importance in this corporate perimeter, providing this necessary cloud security assurance, thus filling any such gaps in the systems running on cloud models.
