Hybrid cloud in simple words
Hybrid cloud is a mixture of private and public cloud which mainly focuses on creating a well-behaved computing environment and offering benefits to enterprises for the deployment of models with focused boundaries and connect to other resource providers as well.
Hybrid cloud offers a flexible and cost-effective environment where one organization can connect their private cloud to other public clouds to share their on-premises data centers. With increasing demand, Hybrid clouds offer the best solution to access both private and public clouds with more security and risk management.
How does a Hybrid cloud work?
Every private cloud is different. Organizations need to connect their private cloud with the public cloud to deploy their applications in a hybrid environment. A third-party application or network does the connection between two separate clouds. The connectivity is performed using LAN, WAN, and VPN and application program interfaces as well.
Why is a Hybrid cloud in demand?
With the help of Hybrid cloud computing, organizations can divide the workload and change the public to private clouds if their business is in demand. The enterprise follows pay – as – you go technique for the usage of resources.
For example, Finance companies or the industries associated with government news to keep specific data confidential for which they can use their on-premise data centers, and for inferior data, it can be stored in the public cloud which helps in managing data and meets the requirements of the organization flexibly.
Benefits of Hybrid cloud computing
Previously organizations used private clouds for application management as well as database storage, which seems unfeasible to pay for resources and continuously expand the infrastructure with new servers. While private clouds have plenty of benefits, hybrid cloud offers the best solutions to organizations to deploy the application models on the public cloud without investing in physical infrastructure which is quite scalable.
Hybrid clouds are the easiest for technical implements which allows the enterprises to choose their security policies, database, and workloads according to the requirements. The internal IT department can work on sensitive data. Only privileged persons can access the restricted data, considering the two-way authentication maintains security standards.
Pay as you go model in hybrid clouds proves to be much efficient and flexible for enterprises. Organizations can easily switch their data from one public cloud to another without paying termination fees offering more agile and modern solutions.
Big data analysis:
The powerful services offered by cloud service allow performing various operations on the data. The cloud computing providers can use hybrid cloud as “software as a service” to process and standardize the data.
Hybrid clouds provide disaster recovery solutions by backing up data in the cloud. Sometimes fail in data centers, Exhaustive workload disrupts the data flow and working module of the enterprise, Hybrid cloud easily scales up your data according to your on-demand services, maintenance and thus reducing the further failures.
Challenges in Hybrid cloud computing
With public and private cloud working together as hybrid cloud, it is quite difficult sometimes to synchronize them due to lack of latency. Both environments need to follow complex security guidelines and compatibility checks to achieve full compliance. The response time of one cloud comparatively varies than the other cloud which does not meet regulatory compliance standards.
Sufficient bandwidth, management of private as well as public cloud, the requirements for application, and different geographical locations are considered in hybrid cloud computing. Network developers must meet the requirements to provide the best solutions and eliminate the network problems faced in the Hybrid cloud.
Strong encryption is required to offer the best solutions to Hybrid clouds. Improper migration of cloud data and storing it in non-certain areas can cause redundancy and data loss which is profitless to any enterprise. Necessary workloads should be stored in private clouds to avoid changing the data and prevent recurring losses.
Maintaining a Hybrid cloud requires a high technical skillset. Minute errors can cause a great threat to any organization. Many times employees share sensitive data without understanding the importance and thus exposing to vulnerability. Reports state that 80 percent of data breaches are occurred due to human errors.
SLAs in cloud
To set up a public cloud and use a Hybrid computing environment means some authority is also provided to the cloud service providers. If the cloud service provider goes down, it will directly affect the hybrid model of the enterprise as well. The enterprise needs to accept the services, policies, terms, and conditions along with the agreement offered by cloud service providers. The enterprises should consider it thoroughly before setting up a hybrid cloud by reading all the liabilities, terms, and security policies to ensure the well-being of the organization and prevent data breaches.
Does hybrid cloud provide security?
Limiting data exposure to reduce security threats with strong encryption is the best alternative used in cloud computing. If you are working in highly regulated areas, security audits and baselines need to be implemented. The physical security can be maintained by signing an SLA(Service Level Agreement) with cloud service providers.
However, before using Hybrid clouds few points should be taken into consideration such as, sometimes hybrid clouds provide a complex structure due to the integration of two types of clouds. Without a proper connection between the private and public cloud, the organization is running its application on parallel space rather than an integrated environment.
No solution is perfect in IT. To meet the requirements and for scalability, enterprises can always choose the option of cloud computing keeping note of all preventive measures. Some of the top cloud service providers like Microsoft’s Azure, Google cloud platform, and Amazon AWS offer the best deals with secured maintenance and a consistent approach for hybrid architecture.
