mobile cloud computing is an emerging technology that combines the power of cloud computing with the ubiquity of smartphones. This technology enables smart devices to access cloud computing resources. It offers various advantages, such as increased storage capacity, improved processing power, extended battery life, higher storage spaces, and faster response times. Mobile cloud computing has the potential to revolutionize mobile computing by providing users with anytime, anywhere access to cloud-based services and applications. However, mobile cloud computing faces many challenges, such as security, privacy, and network issues. This paper presents an overview of mobile cloud computing, its benefits, and challenges. We employed a descriptive approach to collect data on various programs and systems that rely on cloud computing, including automated video surveillance systems, health applications, MISSION SWACHHTA, car sharing for delivery and parcel customers, banking applications and systems, e-commerce platforms, big data systems, e-learning systems, and logistic systems.
