Developing Application Specific Integrated Circuits(ASIC) for cloud computing

Abstract

Cloud computing is the emerging computing technology platform which resolves for a single platform for diversive applications. The paper takes up the issues of security, migration of applications from an internal data centre into cloud, scalability, billing and security. The paper thus points out the hardware incongruence for the cloud computing and presents key concepts for fabrication of VLSI chips. For example, the bills for cloud storage access is based on I/0 count. This metric is inaccurate since the cost of handling the bits varies from disk to disk. This arises due to variance of random access and sequential access used in disk. In sequential access, data is written to or read from one portion of the disk in a continual stream of bits. In random access, the disk head must jump around to different parts of the disk to read or write data. This disparity is immense since, sequential access can achieve a throughput on an average disk of up to 63.5MB/s (megabits per second), whereas random access can only be executed at 1.5MB/s. Techniques for reducing the random access and unnecessary metadata lookups are analyzed. The external threats for cloud from hardware hacking is attended and key alternatives are suggested for networking environment.
