What is Hybrid Cloud? When enterprises need to have the best of work environment, then they go in for a system that combines public cloud, private cloud and single-tenant (on-premise) dedicated environments; and this concept is called as the hybrid cloud. This logical middle ground helps enterprises to strike the perfect balance between on-premises and cloud storage where some of the services existing in these environments are bound together but remain unique entities. This system of hybrid cloud offers the benefits of multiple deployment models and this integrated cloud service performs distinct function within the same organization.
Let us understand now what is hybrid cloud storage; it is about the management of storage, which makes use of both, the local as well as the off-site resources. This helps most firms in supplementing their internal storage with their public cloud storage.
Let us understand now about what is hybrid cloud security; When there is data flowing between the multiple cloud service platforms, then enterprises have to make sure that the data moving between the two clouds is protected. Also, they need to ensure that the sensitive data is not transferred to a less secure storage system in a public cloud from the acquiescent database on a private cloud.
In a hybrid cloud environment, a minimum of one private cloud (internal cloud) and one public cloud (external cloud) is present. Hybrid cloud hosting allows enterprises for the provision of dedicated storage servers and shared storage servers on the same network.
Cloud technology offers the best solutions for better business practices like instant collaboration and powerful data management and this is precisely the reason why enterprises are gradually moving their increasing data portions to the cloud. But even now, many businesses prefer the hybrid cloud model, wherein, some of the data reside in the cloud and rest of the data resides on-premise.
The reasons why enterprises prefer to keep some of their data on-premise are varied and many. One of the crucial reasons is that of data security and compliance regulation that requires strict decisions of data residency. The other reason is the strong security solutions that the on-premise apps offer, making the enterprises reluctant to turn to cloud technology for the fear of cyber attacks and data threats. Also, there is the cost of investment issue and enterprises would want to take full advantage of their paid and designed on-premise application. But, in a hybrid model, it is ineffective if enterprises go in for separate security solutions for the two environments. This will hamper the crucial correlations and behavior patterns that exist between the two; private and public environments. But obviously, there is a perceived gap between the two entities when seen from a data management and security standpoint due to the separation of data. Cloud Access Security Brokers with their CASB solutions help most corporate entities to fill in this gap and provide adequate data security to the hybrid cloud environment.
The unified hybrid cloud environment varies from an individual private on-premise or public cloud environment and hence its security needs also vary. This requires a full, unified approach across both the entities. The best way is to leverage the strengths of the individual entities by effectively integrating the features of the best-in-class CASB solutions with their high-end security modules. CASB solutions for cloud security can be included with the on-premise security, thereby, enhancing the security of the hybrid cloud environment. The already existing CASB security infrastructure can be converted to a cybersecurity hub for the hybrid cloud model. The exceedingly extensible CASB solutions help enterprises to detect suspicious incidents due to their ability to correlate security events taking place across the public and private platforms; thus, reducing the data risks that would otherwise pose grave danger to the enterprise.
What is Hybrid Cloud and How to Secure Data? Effective deployment of heightened integration like the on-premise DLP solution, Multi-Factor Authentication (MFA), Single Sign-On (SSO) etc., helps enterprises to substantially secure their sensitive data on the hybrid cloud no matter where it resides. The private and public entities require that the enterprises integrate their on-premise DLP solution with the cloud CASB solution for effective and adequate hybrid cloud security.
