Cloud middleware and cloud system

Cloud middleware and cloud system

In Chapter 2nd, we have introduced the similarities and differences between HPC and grid computing. in the previous chapter, the author classifies grid systems as one of HPC high-performance computing (non-single-point super computing) systems, this is from the perspective of "computing power". Due to the development of HPC and grid to commercial applications, the concept of grid computing has been given many new features, almost equivalent to IAAs in the cloud computing system, HPC seems to have become a dedicated super computing. Therefore, we previously pointed out that cloud computing is a combination of grid computing and SOA/SaaS concepts.

As shown in Figure 9-1, an industry (early Sun) cloud computing system "timeline Chart" lists middleware as the core of a cloud computing system. However, in terms of cloud computing, currently, the term "Middleware" has not been widely used to express and summarize all reusable software. Instead, it directly lists commonly used and representative software, for example, hadoop, mapreduce, and bigtable (these software are mainly used in the search industry with a narrow scope. As described above, these systems are also integrated with HPC middleware (such as MPI and Condor, this shows that the general cloud computing middleware has not yet formed a large enough scale. However, the word cloud middleware has already appeared in the industry, and more people have begun to use it. For example, all cloud computing software of wso2 is called cloud middleware ([], as shown in 9-2). The author believes that with the development and popularization of cloud computing, cloud middleware will be paid more and more attention, grid middleware (including HPC middleware) will be integrated or combined with enterprise-level middleware, as shown in Figure 9-2 to form IAAs and PAAs middleware and generate a huge industrial chain.
