1. Designing an Effective Cloud Strategy Based on Multi-Cloud Architecture Multi-Cloud is becoming a key asset to the tech industry. The technology has pros and cons yet is widely used by companies with large amounts of data. The basic idea behind multi-cloud is using two or more cloud services to get the most cost-effective and innovative services. Major perks of the technology are avoiding vendor lock-in, risk management, and scalability. Along with the perks, some common difficulties that can be faced are higher costs, increased workload, cloud sprawl, and more. To get the most out of the multi-cloud technology for your enterprise, it is essential to design an effective cloud architecture that is service and event-driven. Cloud computing architecture is mainly divided into Front End and Back End. As the name suggests, Front End is what the client encounters and uses. It has all the interfaces used by clients to access the cloud platform. It includes thin & fat clients, web servers, and mobile devices. In contrast, service providers manage the resources to provide cloud-based services via Back End. It includes servers, deploying models, virtual machines, data storage, and more. Back End combines application, service, Cloud Runtime, Storage, and Infrastructure. A multi-cloud approach can include various cloud services with different APIs, which can be challenging to manage by the companies. Hence, making a multi-cloud architecture according to the needs and audience of the company is crucial. A strategy is required when your audience is not in the exact location you operate or is located in different parts of the world with varying localization laws. Some commonly used multi-cloud architecture are Cloudification, Multi-Cloud Relocation, Multi-Cloud Refactoring, Multi-Cloud Rebinding, Multi-Cloud Rebinding with Cloud Brokerage, and Multi-Application Modernization. These architectures are based on different service providers and your needs. Making an effective cloud strategy changes the course of your data storage and management. What Are the Business Benefits of Multi-Cloud Architecture The multi cloud computing architecture allows businesses to avoid dependence (lock-in) on a single supplier. Some leading cloud service providers are Microsoft, Amazon AWS, Azure, Google Cloud Platform, and IBM Cloud (very present in Asia and currently used mainly by small and medium-sized industrial enterprises is also Alibaba Cloud). A second benefit that businesses using multi-cloud architecture is business continuity. In a multi-cloud architecture, data and applications are replicated on various environments, which operate in an active model (both are always active and share the workloads) or active-passive (one of the two only performs a backup task). One of the other significant reasons for choosing the multi-cloud is the possibility to choose, from time to time, which one to purchase a specific service based on the best performance-cost ratio (cost-effectiveness). In addition, throughout its history, each cloud service provider may have focused on some technologies or types of services rather than others. The more businesses stop thinking that

2. most of their IT assets must be on-premise, the more they can find best-of-breed solutions on the cloud that would be challenging and costly to develop or install in-house. Conclusion When choosing public clouds and multi-cloud service providers, it may be appropriate to consider large hyperscalers and less known service providers specialized in communication and IT infrastructures.
