2. Service Content

   Service Item	Service Content
   Architecture stability	Identifies problems and provides optimization recommendations based on the analysis of services, application architecture, and technical architecture. Problems identified and optimization will cover: Service performance and scalability, including dynamic and static separation, traffic distribution, isolation and decoupling, traffic limiting, and downgrading Data access speed, including cache and database optimization Single point of failure (SPOF) and no data backup
   Capacity	Provides capacity optimization recommendations based on customer service analysis and the expected peak traffic. Provides support in adjusting the number of clusters deployed and the specifications of cloud services.
   Security	Conducts security assessment and provides optimization recommendations from four dimensions (access security, application security, data storage security, and management security) based on customer services.
   Monitoring and alerts	Checks the alarms, resource load, and health status of Huawei Cloud services, analyzes service architecture, scenarios, and historical faults, and provides monitoring optimization recommendations based on Huawei Cloud monitoring configuration best practices.
   High availability	Assesses the fault impact and recoverability and balances key metrics, including RTO, RPO and TCO to provide recommendations for AZ-level high availability deployment.
   Switchover drill	Performs switchover drills for the cloud environment, system architecture, system performance, and emergency plans through active/standby switchovers, cluster HA, and backup and recovery, to verify the stability of service systems, identify risks in advance, and provide optimization recommendations.
   Performance	Performs concurrency testing for various web application scenarios, including login, overview, and query, to identify customer system bottlenecks and provides optimization recommendations based on metrics in the CPTS report, such as the number of concurrent requests, transaction success rate, and response latency. Note: This service item applies only to stress tests supported by CPTS and does not include the fees (for VUM packages, test clusters, bandwidth, and EIP) generated by using CPTS during tests.

Prerequisites

1. Customers shall apply for the Health Check Service 10 working days in advance so Huawei Cloud can assess the service feasibility.
2. Customers shall authorize Huawei Cloud to monitor and analyze their cloud resources.
3. Customers need to purchase resources for pressure tests.
4. Customers shall not deny the recommendations or solutions confirmed by both parties without justified reasons.
5. Customers take on major responsibilities for the O&M and need to perform related work.

Service Scope

1. Service Items covered

   Huawei Cloud provides the consultation, usage, and configuration best practices on the cloud architecture, capacity, security, and monitoring.

2. Service Items not covered
   1. Designing and O&M of application systems, including but not limited to customer application development, test, deployment, migration, and fault diagnosis
   2. Installation, configuration, patch update, test, fault diagnosis, and optimization of third-party software
   3. Internet Data Center (IDC) and hardware maintenance, including inspections, replacements, and diagnosis of network devices, servers, and storage devices

Service Process

"N" indicates the time when the service application is submitted. "Day" indicates a working day.

Both Huawei Cloud and customers should participate in the requirement confirmation. The two parties shall clarify service contents and results. If the two parties cannot reach an agreement, the service cannot be provided.
