There could be several solutions that make a multi-cloud environment. There are numerous types of cloud computing services that emphasize security and offer the best solution to keep things in control. The new private on-premises cloud-based information system keeps things secure, divides the workload, and keeps things on track. Hybrid clouds help in the management of all types of data within the organization. A hybrid cloud is a combination of both private and public clouds. The current cloud is not secure and safe enough to manage and keep data for the long term. The organization is using the public cloud that helps manage malicious attacks in a public environment, and this gap could be filled using a hybrid cloud environment. Despite hybrid cloud is an extremely important enterprise paradigm, there are still important open issues to be addressed related to intermittent connectivity, transparent support, policy enforcement management, management of resources under strict service level agreement (SLA) conditions, as well as privacy and anonymization issues related to data and workload portability across the hybrid cloud. Depending on the infrastructure of each company and the needs of each business, a hybrid cloud is helpful in the management of business operations. Trends of hybrid cloud and multi-cloud become a need of every small and large business enterprise. Due to an increase in encrypted HTTPS traffic, inspecting data and preventing attacks pose a significant challenge for todays security professionals. A new SSL intercept capability solves this challenge by decrypting HTTPS traffic on a high-performance, scalable platform, making clear text traffic available to third-party security services and devices, and re-encrypting traffic in a transparent manner to clients and servers (Gale 2021). The paper further provides a detailed literature review related to the public cloud and hybrid cloud implementation within the workplace to transform proposed business processes, security standards, and management of workload. Literature Review Hybrid And Multi-Cloud Management Platform is far better than a cloud system, and it is proved through the applications and adaptation of hybrid cloud management platforms across business industries. Hybrid And Multi-Cloud Management Platform offers higher security-resilience, flexibility, and deployment of business processes that seem too cost-effective and timesaving. The workload could be deployed into a positive and manageable work environment in a multi-cloud work environment that cant be handled in a single cloud environment. The implementation of the single cloud couldnt make sense and fails to meet security and business requirements (CDW, 2018). But the implementation of both cloud and hybrid cloud infrastructure will be an option that will bring dual security for organizations. When it comes to cost analysis, the public cloud is a cost-effective option. Still, it didnt seem effective in providing enough storage and bandwidth to keep organizational documents and deployment of data. Enterprises seeking flexibility, maintenance, cost-benefit, and security, and single cloud implementation is not an effective and efficient option, but it needs a hybrid or multi-cloud implementation (Khan & Ullah, 2016). Cloud management software or multi-cloud environment helps deploy external and internal clouds with a user application and enables organizations to manage their operations effectively. In the modern business world, organizations deal with complex technologies. Thus, they need technologies that do not waste time and money but manage workplace operations and comply with the organizational goals. Along with the advancement and innovation happening everywhere globally, concerns regarding the security and safety of business operations also increased. Research says that 80\% of the business applications are taking shifts towards cloud opportunities and optimizing supply chains because cloud solutions efficiently provide security and safety (CDW, 2018). Researchers further say that business executives are invited to invest in hybrid multi-cloud platform strategies and focus on integrating hybrid multi-cloud platforms within the organization to enhance organizational operations and management of security concerns. 68\% of businesses focus on implementing advanced cloud and open-source cloud platforms to transform business practices (Comfort, Dolph, & Robinson, 2020). New business models in the 21st century emphasize integrating hybrid multi-cloud platforms as a fundamental part of business planning. It is what they wanted to do to transform the infrastructure of business organizations. The value derived from a hybrid multi-cloud platform is 2.5 times higher than the value derived from a business organization running on simple advanced technologies (Comfort, Dolph, & Robinson, 2020). by keeping organizational operations secure and safe hybrid multi-cloud platforms transforming the way businesses operate for years. There are different ways IT and cloud are being used in business organizations, such as some organizations using the cloud for optimization of the supply chain, some are using the cloud to bridge the longstanding difference between business and innovation, and some are using it to embrace digital transformation. But in coming years, cloud or cloud-based platforms will become an important need and unmet requirement. Cloud platform or hybrid multi-cloud strategy cannot be designed in isolation, but it needs a context of the business objectives and specific limitations to achieve strategies. To ensure that there wont be gaps in the proposed strategy, it should be viewed holistically and put together all the parts. Research says that only 27\% of businesses offer a holistic multi-cloud management strategy and provide an overview of the organization before implementing a hybrid multi-cloud strategy (Comfort, Dolph, & Robinson, 2020). The current system is not effective and efficient enough to meet the needs of individual organizations; thus, the comparison with the hybrid multi-cloud interface shows us that it is required and should be implemented in every business setting regardless of the size and purpose of the business. Privacy and confidentiality of information can also be protected under secure and strong security paradigms. Literature on hybrid data and cloud is not abundant; that is why there are numerous gaps that the study will cover by showing the difference between cloud and hybrid multi-cloud systems (Chuang, Chang, & Sung, 2011). Along with managing administrative workload, multi-cloud also contributes to enhancing business security. Regardless of the need posed by modern business, cloud-based business is a relatively modest choice. Security, accessibility, and control are major risks associated with the public cloud system, and these needs motivated the implementation of a hybrid multi-cloud system. The organization that merely relies on the public cloud faces difficulty and loses control over the organizational data and management of internal and external processes (Géczy, Izumi, & Hasida, 2013). Systems Analysis Diagrams The old system has a single Cloud Service Provider (CSP) using ASW + Nethub Existing System Problem Statement, a single cloud environment in Information Technology (IT) data services provided by cloud providers (CPs) face significant challenges in maintaining services and their continuity during a disaster. The primary concern for data recovery (DR) in the cloud is finding ways to ensure that the process of data backup and recovery is effective in providing high data availability, flexibility, and reliability at a reasonable cost. Numerous data backup solutions have been designed for a single-cloud architecture; however, making a single copy of data may not be sufficient because damage to data may cause irrecoverable loss during a disaster. NIST defines four cloud deployment models: · Public clouds (cloud infrastructure made available to the public or a large industry group) · Private clouds (cloud infrastructure operated solely for an organization) · Community clouds (cloud infrastructure shared by several organizations) · Hybrid clouds (cloud infrastructure that combines two or more clouds) Existing System Use Case Listing and Description of Goals Use Case # User Action System Response 1 Cloud Service Provider (CSP) Develops software and other assets for consumption on the cloud.

A hybrid cloud environment combines the advantages of public clouds and private clouds, users save encrypted data in public clouds while using private clouds to compute resources. The provider of the hybrid cloud must manage cloud resources based on the consumer’s terms. Servers supporting the web site must be hosted in a data center with access from the public Internet. Traditionally, this has been achieved by renting space for physical servers in a hosting center operated by a network provider far from the enterprise’s internal systems. Targeted at data center and edge computing use cases, customers can leverage the reference architectures to rapidly deploy enterprise-class applications on their existing hardware infrastructure and efficiently handle complicated hybrid- and multi-cloud tasks (Gurgaon 2020).

The hybrid cloud model provides the best of the private and public worlds, combining the economies and efficiencies of public cloud computing with the security and control of private cloud computing A hybrid multi-cloud system is efficient to meet the business security, safety, accessibility, and digital needs. Implementing a hybrid multi-cloud system will bring positive change for the business organizations that will schedule the ability of a business to cope with challenges. Both clouds differently handle security issues in the business setting and thus make a difference and shape our perception regarding implementing the specific cloud to carry out business operations.
