This document summarizes a seminar on key challenges in cloud computing. It introduces cloud computing and the three main types of cloud services: SaaS, PaaS, and IaaS. It discusses how cloud computing can enable future internet of services by providing on-demand access to applications, platforms, and computing infrastructure. Several issues that must be addressed to realize this vision are discussed, including deploying cloud infrastructure, managing large clouds, developing aggregation architectures, and improving security, reliability and energy efficiency. Key challenges for enabling future internet of services through cloud computing are identified as supporting application elasticity, assuring quality of service, improving scalability, reliability, privacy, security and energy management of cloud infrastructure, and enhancing cloud

19. Conclusion
Thus cloud computing provide a supercomputing power.
This cloud of computers extends
beyond a single company or enterprise.
The applications and data served by
the cloud are available to broad group
of users, cross-enterprise and crossplatform
