Hybrid cloud is referred as a computing environment that collaborates private cloud as well as a public cloud by enabling applications and data to be shared among them. During fluctuation in computing as well as processing demand, the hybrid cloud provides organisations with the potential to seamlessly scale on-premises infrastructure to the public cloud. This helps to manage overflow without providing third-party data centres accessibility to the entirety of their information. Adopting a hybrid cloud not only enables organisations to scale their computing resources. Moreover, it also eradicates the requirements to make huge capital expenses to manage short-term spikes in the business needs and demands.
Features of hybrid cloud
- Cost efficiencies: Public clouds are more likely to provide highly significant scale economies, hence more cost efficiency as compared to private cloud. Hybrid cloud, thus enables enterprises to access savings for several business functions while maintaining secure sensitive operations.
- Security: Private cloud component of hybrid cloud model not only offers security when it is required for sensitive functions but also satisfies the regulatory specifications for data management where these are applicable.
- Scalability: Availability of both secure resources and elastic cost-effective public resources provides enterprises with higher opportunities to investigate various operational revenues.
Risks associated with hybrid cloud
- Loss of control: One of the most crucial risks of hybrid cloud is perceived a loss of control. There is a change in applications all the time, and when such applications are outside the control of the organisation, they can be caught unprepared during a sudden update in the software. Single application change can generate integrate issues, resulting in high disruptions amongst the crucial business applications.
- Cloud security: Other major security issues for enterprises that implement hybrid cloud strategies involve poorly constructed service level agreements, security management and risk management. Most of the issues originate from complications when both public and private cloud involved in conjunction with one another. Hence, management of two types of deployments is regarded as a difficult task for IT teams.
- Compliance: This is another concern which goes along with preceding security issue. Businesses need to assure that all sections of the cloud strategy are compliant with industry regulations. It is necessary to assure that information travelling among public and private cloud environment is secured as well.
Best practices to manage risk hybrid cloud environment
- Assess risk, tolerance as well as treatment: Security teams must meet the business stakeholders for determining which assets are most crucial to the business. The target is to measure the probability of a particular threat producing a negative impact on business.
- Develop effective controls based on risk treatment: When risks are quantified, and risk appetite is defined, then the consequent risk treatment strategies drive the program in a prioritised, pragmatic and rational manner. A vital part of risk management is creating strong data categorisation as well as data lifecycle management procedures. Striking an adequate balance between productivity and risk involves instructing end users regarding their role in securing the assets of the organisation. The objective is to permit users to understand these risks by remaining productive and innovative.
- Ensure visibility across endpoints: One of the problematic aspects of protecting hybrid cloud is its scalable nature having an ever-changing combination of network and compute resources placed in different locations, e. both public and private domains. For the effective security of resources involving virtual servers as well as software-defined networks, IT should maintain an inventory of endpoints as well as services. This helps to map every component to risk analysis to determine the resources linked to various workloads and applications.
- Templatize services for bringing shadow IT to light: As enterprises implement a wide and varied combination of services across public and private cloud environment, it is essential that advanced processes are kept in place for the integrated security. Every deployment needs various approaches to risk management.
