Whether it is a public cloud or a private cloud, the construction and application are arduous and complex tasks that cannot be accomplished overnight.
A few days ago, I interviewed a domestic company with the leader.middlewareThe company, on the way, the leader throws out a new point of view: cloud computing is actually a big middleware. As soon as these words came out, I was puzzled at the time. Why is cloud computing related to middleware again?
Thinking about it, the two really have some origins. Isn’t cloud computing based on the principle of middleware? In other words, cloud computing is a new kind of middleware.
If you look at it from an IT architect’s point of view, you will definitely find some similarities.We put the business model of cloud computing aside, and only focus on how the cloud computing platform provides services. Then, what we will see is a software service platform, which is conceptually the design of amiddlewarecore principles. This is especially true from an application and data integration point of view.
The biggest advantage of middleware is that it does not move the existing system, but inserts a new system to facilitate data migration; second, it is convenient to provide personalized services.
According to the hierarchical classification of cloud architecture, the cloud environment can provide three levels of services: Infrastructure as a Service, Platform as a Service, and Application as a Service.
In terms of physical structure, the entity of cloud computing consists of a large number of computers distributed in various places; but for users, all they see is only one computer, and the computing resources provided can be dynamically adjusted as needed , other physical substance and management details are completely shielded from the vision of users and even managers. From the perspective of computing resource management, cloud computing is a management method that treats a large number of highly virtualized resources as a single huge computing resource that can be used to deliver elastic scale services.
And all this seems to be the realization of a greatmiddlewarefunction. So, what is the concept of “cloud computing middleware”? In fact, this concept has already been discussed.
Extract common problems and solutions in distributed computing resource management, perform performance optimization and fault-tolerant processing for different resource types, and then provide them to application service developers through a unified management engine and development platform. This is cloud computing. The technical concept of middleware. Cloud computing middleware utilizes multi-level distributed virtualization technology, intelligent system management and automatic resource allocation to enable enterprises to quickly and effectively build and manage “cloud” platforms. With the help of cloud computing middleware, application service providers can be freed from complex and tedious distributed computing resource management problems, and concentrate their energy and financial resources to provide their users with better search, email, enterprise management and other services.
cloud computingmiddlewareEffective integration of various computing resources is an indispensable cornerstone for building a cloud platform. It can help users build a virtual service environment and help enterprises quickly use cloud computing technology to complete the smooth migration from traditional architecture to cloud computing architecture. This platform enables any enterprise to use a computer cluster like a single machine, making it possible to manage large-scale systems and process massive amounts of data that were previously unimaginable.
Although cloud computing can more effectively integrate and utilize existing IT resources and provide efficient and reliable computing services, the construction and application of both public and private clouds is a arduous and complex task that cannot be accomplished overnight. In particular, it is necessary to consider making full use of the existing software and hardware platforms, and to migrate a large number of existing applications and data to the cloud computing platform, which is a critical and difficult process.
