1. Introduction
Developers who are attempting to build software solutions with large models fall into two main categories. There are professional developers who are familiar with machine learning techniques and can train, fine-tune and deploy large models on their own. However, these developers face hardware infrastructure challenges, and training a large model like GPT-3.5 requires a huge GPU cluster to run for a long time. Another type of developer needs to eliminate hardware computing power constraints and focus on the actual development and integration of model applications. In this context, the combination of AI and cloud-native technologies is increasingly important. Due to the huge demand for storage and computing power in large models, the vast majority of AI applications need to rely on cloud support especially for large model applications.. As a result, cloud-native technology has become a standard option for developers, and developing, deploying, and operating AI applications will become a standard skill and workflow for every developer. With the historical turning point of personal computer and mobile Internet innovation, the software industry is once again standing at a new historical starting point.

2.1. Cloud-native
The concept of cloud computing was first proposed by Dell in 1996. In 2006, Amazon took the lead in launching Elastic Compute Cloud (EC2) [1]services, and then more and more enterprises began to gradually accept the concept of cloud computing, and gradually migrate applications to the cloud, and enjoy the technical dividends brought by this new computing method. Cloud-native technologies provide the necessary infrastructure to build and run elastically scalable applications for a variety of cloud environments, including public, private, and hybrid clouds. Representative cloud-native technologies include containers, service grids, microservices, immutable infrastructure, and declarative apis that help build loosely coupled systems that are fault-tolerant, easy to manage, and easy to observe. Combined with automation, cloud-native technology enables engineers to easily cope with frequent and predictable major changes to their systems. Cloud computing provides sufficient computing and storage resources to enable intelligent assistants such as Siri, Alexa, and Google Assistant to perform complex tasks such as natural language processing, speech recognition, and machine learning, thereby greatly facilitating everyday life. Therefore, combining cloud-native technology with intelligent assistants can not only enhance the user experience, but also bring more efficient development and operation processes for enterprises.
2.2. Cloud-native distributed infrastructure
The cloud computing infrastructure architecture takes distributed multi-cloud as the core, builds the "one cloud and multiple computing" converged base, relies on the unified management of heterogeneous resources and the distributed task collaboration framework, builds a new service system with AI running through it, supports the integrated carrying capacity of general computing, intelligent computing, supercomputing, and network convergence services, and ensures the availability of full-link services. In terms of overall architecture, the hierarchical system of traditional cloud architecture is retained. In the cloud network resource construction, it emphasizes the distributed optimal layout of multiple types of resource pools. Diversity is emphasized in the software and hardware resource layer, which is further divided into CPU-based general computing infrastructure and intelligent computing infrastructure dominated by AI-accelerated chips such as [2]GPU. The distributed cloud platform manages multi-dimensional heterogeneous resources in a unified manner and implements efficient collaborative task scheduling. On the basis of infrastructure architecture, cloud service forms show a trend of generalization and intelligent development, carrying multiple business types, and providing rich industrial digital capabilities.
Because search engines need to process huge amounts of data, Google's two founders, Larry Page and Sergey Brin, designed a file system called "BigFiles" in the early days of the company. GFS(full name "Google File System") this distributed file system is a continuation of [3]"BigFiles". First, to introduce its architecture, GFS is divided into two main types of nodes:
1.Master node: mainly stores metadata related to data files, rather than chunks. Metadata includes a table that maps 64-bit labels to the location of the data block and its constituent file, the location of the copy of the data block, and which process is reading and writing the particular data block. The Master node also periodically receives updates (" Heart-beat ") from each Chunk node to keep the metadata up to date.
2.Chunk node: As the name implies, it must be used to store Chunk. Data files are divided into chunks with a default size of 64MB. Each Chunk has a unique 64-bit label.
Among them, the distributed infrastructure also has intelligentization oriented functions. Due to the low degree of interaction among heterogeneous resources, high matching complexity, difficult to ensure the balance after adjustment, insufficient consideration of service characteristics and other problems, distributed infrastructure has the following functions: Therefore, the resource supply mode changes from providing fixed computing resources to flexibly adjusting the resource usage for specific service scenarios.
2.3. Cloud-native Core feature
The core characteristics of cloud infrastructure are wide distribution, high performance, and hyperscale:

To provide comprehensive connectivity and highly reliable network protection, integrating connectivity across air, sky, and sea.; Provide consistent services in different geographic resource pools, and provide one-click cloud network resource supply anytime, anywhere.
(2) High-efficiency hardware resource supply. Based on the green advanced multi-component computing power, more than ten times the computing performance improvement. Build a new type of intensive and efficient storage to provide mass storage requirements under the digital wave. Promote the innovation of system-level network disconnection cooperation system, and build a low-consumption high-speed interconnection network between 100,000 nodes[4].
(3) Ultra-large scale management and scheduling. The scale of data management and control continues to increase, providing multi-modal data management and scheduling of PB-level large data volumes; Support complex business requirements logic cumbersome, frequent interaction of modular management, to achieve complex business logic-oriented management scheduling; Massive data and highly complex algorithms drive the cloud platform to achieve unified management and control of more large-scale computing power.
A variety of learning methods based on AI models and even large models can design and generate adaptive intelligent planning and scheduling policies based on training models for business needs to improve the scheduling superiority of large-scale resources. Multi-level scheduling of Services Level Indicator (SLO), service level indicator (SLI), topology-aware scheduling, and off-line business mixing to maximize resource utilization.

The solution architecture of intelligent air conditioning products is generally composed of "intelligent air conditioning + cloud service + mobile APP", [6-7]in which the cloud service stores various attribute parameters of intelligent air conditioning, and the cloud service communicates with intelligent air conditioning through the Internet to ensure the real-time property parameters of intelligent air conditioning on the cloud service. The appliance APP can control the appliance by changing the attribute parameters on the cloud service. The solution of intelligent air conditioning access to Google Assistant voice control is to connect the intelligent air conditioning cloud service with Google Assistant to transmit the relevant control and status parameters of intelligent air conditioning to achieve the voice control of intelligent home appliances. The system scheme is shown in Figure 1.
