Cloud computing systems generally think of three types: Iaas,paas,saas.IaaS is infrastructure-as-a-service, which is the infrastructure that is provided to the user as a service. such as Amazon's AWS and S3PAAs is the platform as a service, that is, the platform as a service to enable users to develop applications, such as Google App Engine,sina app Engine, as well as Microsoft's Azure and so on.SaaS is software-as-a-service, which is the provision of

My last blog, "Two modes of Big Data Processing", discusses the large-format memory-based streaming processing and hard disk-based storage processing. Compare these two processing modes, because the memory processing performance is the hard disk's n magnitude, so the stream processing efficiency is much higher than the storage processing, but the stream processing itself has a disadvantage, or is a worry, l
