A cloud e-commerce platform is going to hold a sales promotion during Christmas. At present, the customer has built an online shopping platform on Alibaba Cloud by using Server Load Balancer (SLB), Elastic Compute Service (ECS), Relational Database Service (RDS), and Object Storage Service (OSS).
When handling a surge of business traffic during the past holiday sales promotions, the customer's platform encountered the following problems: Because of great purchase demands for certain holiday products, the number of access requests for such products was too large, resulting in image loading failures on shopping pages.
Transaction pages of hot-selling products were loading slowly or even could not be opened. To build the cloud architecture in advance to cope with the growth of business traffic during the sales promotion, if you are an Alibaba Cloud architect, which of the following solutions do you think are the most reasonable and effective?
(two correct answers)
Response:

• A. Enable Alibaba Cloud Content Delivery Network (CDN) and separate the details pages of hot-selling products from those of general products in the business system. Statically process the details pages of hot-selling products to allow servers to dynamically determine only user clicks for buying products, and cache other static data on CDN.
• B. Configure existing RDS instances as single RDS instances to improve database performance.
• C. Use the data control module of the business system to cache the data of hot-selling products in advance on ApsaraDB for Redis, implementing high concurrency and relieving the RDS access pressure.
• D. Change the instance type to upgrade the configuration of SLB instances and increase the bandwidth to handle the traffic surge.
