As an architect to design a website with a daily PV of up to 100 million times, to achieve high performance in the follow-up, it needs to be realized through reasonable architecture design.
Which of the following descriptions about the elements that need to be considered in high-performance architecture design is wrong?

• A.To comprehensively consider the overall factors that affect the performance of the architecture, such as I/0, synchronization, concurrency, resource contention, and large data volumes. Usually, I/O operations. Algorithms with poor network response, databases, and Other inefficient resource usage can lead to poor performance
• B.It is necessary to consider the issue of intranet bandwidth, such as whether the HUAWEI CLOUD computer room can withstand 100 million PVs and the incoming traffic
• C.To consider the application itself, such as code execution optimization, software design multi-threaded or multi-process
• D.Fully consider network performance, such as bandwidth between external network access, data transmission efficiency, network path, etc.

According to the performance of cloud hard disk, the disk can be divided into ordinary IO, high IO, general-purpose SSD and ultra-high IO.

• A.False
• B.True

• B.Containers deployed through CCE only support isolation in the form of Cgroups
• C.Node nodes can choose ECS, BMS, DeH and other hosts
• D.The nodes of CCE can be divided into Master-node, Node node and Backup node

Which of the following options is the correct process for enterprises to go to the cloud?

• A.Plan>Design>Verify>Implement>Delivery
