Overview

The cloud architecture consists of the infrastructure, applications, and big data.

Figure 1 Cloud architecture

1. Basic environment design: Before migrating workloads to the cloud, you need to prepare the basic environment. The basic environment, often referred to as the landing zone, encompasses a comprehensive design framework that addresses six aspects: account and permissions, network, security strategy, resource governance, O&M monitoring, and financial management.
2. Application deployment design: Application deployment indicates the technical architecture of cloud applications. You need to design the access, application, middleware , and data layers as well as cloud service technologies for each layer. It is essential to consider six key elements: availability, performance, scalability, security, cost, and maintainability. Particular emphasis should be placed on availability, scalability, and performance, while ensuring that security, cost, and maintainability align with basic requirements of the environment.
3. Big data architecture design: The design of big data architecture encompasses several key components: big data clusters, big data task scheduling platforms, and big data applications. You can refer to the application deployment design.

To design a more efficient, flexible, and scalable cloud architecture, you can refer to TOGAF ADM (a widely-used framework for developing architectures) across four domains, best practices, and tools.
