TechSoft Solutions, a rapidly growing technology firm specializing in software development and IT consulting, operates across regions, including Europe, North America, and Asia. As part of its expansion strategy, the company is planning to diversify its IT infrastructure by adopting a cloud strategy. This approach aims to enhance system resilience, optimize costs, and ensure compliance with regional data protection regulations.

The company$$s leadership is particularly concerned about the complexity of managing cloud environments and ensuring seamless data retrieval and storage across these platforms. The Board of TechSoft has requested your team to provide a comprehensive plan and risk assessment for the transition to a cloud strategy. They are especially interested in understanding the implications for their information storage and retrieval processes and the security challenges that may arise from operating in a cloud environment. $1.$ Design a cloud architecture that TechSoft Solutions could adopt, integrating their private cloud with multiple public cloud services. The design should address the specific needs of the company, including redundancy, disaster recovery, and compliance with data protection regulations.

$2.$ Justify your choice of cloud service models $($e$.$g$.,$ IaaS, PaaS, SaaS$)$ and explain how this architecture will support TechSoft$$s goals for resilience, cost optimization, and compliance.

$3.$ Evaluate the impact of the cloud model on TechSoft$$s information storage and retrieval processes. Analyze how data will be managed across different cloud platforms, including data access, retrieval speed, and consistency issues.
