manual 1, Google App Engine usage process (1) Sign up for a Google account, fill in the registration information, log in (2) Create a Google App Engine app, complete the verification by mobile phone number, fill in the application details (note that the app's identifier cannot be changed) (3) Download the App Engine SDK (4) Develop applications locally using Python or Java language to complete local debugging (5) Run the program after uploading it to Google App Engine 2, Amazon AWS use process (1) Register your Amazon account, fill in the registration information, login (2) Select the required services to register as needed, fill in the relevant information, and complete the service configuration (the number of required resources is required for the IaaS type service, and the setting parameters are required for other types of services) (3) uploading applications or pending data, sometimes uploading additional programs as required (4) Run the service until the result is obtained (5) Stop using, pay relevant fees according to actual usage 3, Microsoft Azure use process (1) Enter the Live ID on the Azure page, register for the Azure account, fill in the registration information, login (2) Select "Windows Azure" in the project list, then select "Hosted Services" in the New Service Wizard. (3) Create a new "cloud" type project locally, write an application and complete debugging (4) Create an application service package, upload the service package to Windows Azure, set the URL address, select "Deploy", and select "Run". (5) Stop using, pay relevant fees according to actual usage 4, the use of VMware vCloud process (1) Join the VMware Technology Alliance program, fill in the basic information, get the account number and information, log in (2) Select programming language (support Java, C, C++) to write software applications running on different operating systems (including Linux, Windows, Solaris), and use VMware-based cloud computing infrastructure according to vCloudAPI (3) Select the appropriate service provider in the list of VMware certified service providers, or choose to use the enterprise's own cloud computing environment that supports vCloud. (4) Select one of the three modes of virtual machine, virtual device and vApp to deploy the application to the cloud platform. (5) Stop using, if the service provider's service is used, pay the relevant fee according to the actual usage. Architecture The differences in services provided by cloud computing solutions from Google, Amazon, Microsoft, and VMware are closely related to differences in their cloud computing system architecture. Same point: (1) The entire cloud computing platform provides a unified web interface to the outside (2) The details of the background implementation are transparent to the user. difference: (1) Amazon, Microsoft and VMware's cloud computing services are composed of multiple services, which need to provide different portals for different services. (2) Microsoft cloud computing supports cloud and local applications Implementation technology 1, Google App Engine implementation technology In general, it can be divided into four separate but closely related components of GFS, MapReduce, Bigtable and Chubby. 2, Amazon AWS implementation technology The most representative is the basic storage architecture Dynamo, which is a fully distributed storage architecture with improved consistency hash algorithm, vector clock, Merkle tree and other technologies. It has a natural balance in load balancing and system expansion. Advantage 3, Microsoft Azure implementation technology Build a cloud computing system by running Windows Server on a virtual machine, SQL Azure based on SQL Server, etc. 4, VMware vCloud implementation technology VMware takes full advantage of its virtualization technology and virtualizes the computing, storage, and networking aspects of cloud computing to provide cloud computing services based on IaaS. Core Business Comparison of computing services for commercial cloud computing solutions Plastic Injection Insert Molding 1. The combination of the easiness of molding and bending of resin and the rigidity, strength and heat resistance of metal can make complex and sophisticated metal-plastic integrated products sturdily.

2. In particular, the combination of the insulation of resin and the electrical properties of metal can meet the basic functions of electrical products.
3. The pre-forming combination of multiple inserts makes the post-engineering of product unit combination more reasonable.
4. Insert products are not limited to metal, but also cloth, paper, wire, plastic, glass, wood, wire ring, electrical parts and so on.
5. For rigid parts and flexible parts on rubber sealing pad, the complex operation of arranging sealing ring can be eliminated after the integrated products are made by injection molding on the matrix, which makes the automatic combination of the following process easier.
6. Because it is the fusion of molten material and metal insert, compared with the pressing molding method, the metal insert gap can be designed to be narrower, and the reliability of composite product molding is higher.
7. Suitable resin and molding conditions may be used for sealing and fixation of susceptible products such as glass, coils, electrical parts, etc.
8. Inserts can also be completely sealed into the resin by selecting the appropriate mold construction.
9. After the insert is molded, it can also be made into a product with hollow grooves along with the core hole.
10. The combination of vertical injection molding machine and manipulator, the whole row device of insert products, etc., the insert forming engineering can be mostly automated production.
