01_Basics of architectural design
Why consider architectural design
people
Murphy's Law
cloud
There is a capability gap between cloud service capabilities and cloud products
You cannot simply rely on the SLA provided by cloud products to ensure business stability.
design elements
High availability of cloud infrastructure and cloud services
High availability of enterprise operating business environment
High availability for enterprise business and client communications
The evolution of application architecture design
Monolithic architecture: classic three-tier architecture
SOA (Service Oriented) Architecture: ESB Enterprise Service Bus
Microservice architecture
Cloud native applications
Cloud architecture design principles
Fault Tolerant Design Principles
When designing the system architecture, every aspect of the application system (including software and hardware) needs to be considered.
Eliminate single points of failure in application system architecture design to achieve high availability
Development and deployment perspective
Fault-tolerant design for system failure
Loose coupling and stateless design
Expandable and auto-scaling design
Safe design
Service deployment perspective
High availability (HA) disaster recovery and disaster recovery (DR) are two aspects that cannot be ignored in architectural design.
High-availability deployment is aimed at scenarios where the business is completely deployed in the cloud.
Disaster recovery and disaster recovery are designed to connect local computer rooms and cloud services.
High availability architecture design principles
5 aspects
Server-level fault recovery
Fault tolerance and recovery at the cloud service region level
Cloud platform level fault tolerance and recovery
SOA and servitization of application systems
Use cloud tools to build automation platforms and manage infrastructure with code
Typical scenario
Set the application to be stateless, which can be restored by restarting the process or server
Deploy stateless applications behind a load balancer
Set up the elastic scaling function so that the cloud platform can respond according to performance indicators
Set up the basic image template of the application environment to facilitate quick recovery

ServiceStage
what is
The microservice cloud application platform is a one-stop PaaS platform service for enterprises. It provides application cloud hosting solutions to help enterprises simplify application life cycle management issues such as deployment, monitoring, operation and maintenance, and governance; it provides a microservice framework and is compatible with mainstream open source Ecosystem is not bound to specific development frameworks and platforms, helping enterprises to quickly build distributed applications based on microservice architecture.
Basic operations
Create a cluster
A cluster is a logical grouping for running applications and contains a set of cloud server resources, with each node corresponding to a cloud server. When using ServiceStage for the first time, you need to create an initial cluster and add a node.

Upload image
Deploy container applications
An application refers to a set of instances running on ServiceStage. ServiceStage provides third-party application hosting functions and full life cycle management from deployment to operation and maintenance. This section guides users to create your first container application through container images.

switching mechanism
Real-time monitoring through the Monitor component, VIP is bound to the host, and data is synchronized between the master and slave through master-slave replication.
When the host fails, Monitor will automatically initiate 3 connections to the host.
If all three attempts fail, Monitor will initiate a master/slave switchover. The first step is to unbind the VIP. The second step is to wait for the backup machine to replay all relaylogs to catch up with the master. The third step is to promote the backup machine to the master and bind the VIP to the new host ( Original machine)

07_Basics and Getting Started with Cloud Middleware
Distributed Message Service (DMS, Distributed Message Service)
A fully managed, high-performance message queue service that provides ordinary queues, ordered queues, Kafka queues, and ActiveMQ. It is compatible with HTTP, TCP, and AMQP protocols and provides a flexible and reliable asynchronous communication mechanism for distributed applications.
Distributed Cache Service (DCS, Distributed Cache Service)
In-memory database services compatible with Redis and IMDG, based on a high-availability architecture with dual-machine hot backup, provide a variety of cache types such as stand-alone, master-slave, and cluster to meet users' business requirements for high read-write performance and fast data access.
Distributed Database Middleware (DDM, Distributed Database Middleware)
The middleware service solves the problems of database capacity, performance bottlenecks and distributed expansion. It provides the capabilities of sharding databases and tables, separation of reading and writing, and elastic expansion. It can cope with high-concurrency access scenarios of massive data and effectively improve database reading and writing performance.
08_Application orchestration service: assisting the automation of applications on the cloud
Application Orchestration Service (AOS for short)
Deploy applications to Huawei Cloud with one click, simplifying related cloud service management operations. AOS uses templates to describe and orchestrate applications and related cloud services, realize automatic deployment of applications, create cloud services, and provide E2E application full life cycle operation and maintenance management capabilities.
basic concept
template
A text file that follows AOS syntax specifications and describes application properties, cloud service configurations, and dependencies between applications and cloud services. You can manage templates like code, and you can manage different versions of templates like code management tools such as git and svn. Managing applications and cloud services through templates can simplify the cloud design of application systems, easily build and copy development, testing, and production environments, ensuring that application systems are configurable, evolveable, and traceable.
stack
A collection of applications and cloud service resources. The stack creates, upgrades, deletes, etc. applications and cloud services as a whole.
