Question 14

www.company.com is a newly launched social portal for exchanging automotive information. The portal is based on PHP, including 10GB of images, and some

JavaScripts files. Currently one single ECS instance is used to host all the application content as well as a MySQL database. With the growing number of users, the portal is getting slower to load images or respond to user requests. Moreover, there will be additional 50GB image content uploaded to the portal every week.

Which combination of Alibaba Cloud services below can help resolve the storage and performance issue at the same time?

    Correct Answer: A

    To address both the storage and performance issues for the newly launched social portal, using Object Storage Service (OSS) and Content Delivery Network (CDN) is ideal. OSS provides scalable and secure storage, suitable for the large and growing volume of images. CDN accelerates the delivery of static content like images and JavaScript files by caching them at various edge locations close to users, thereby reducing latency and improving load speeds. This combination efficiently handles the storage needs while enhancing user experience by reducing the response time and server load.

Discussion
lhorisOption: A

A. OSS + CDN Use CDN to accelerate access to OSS When you access Object Storage Service (OSS) resources, the access speed depends on the region in which the buckets are located and is limited by the downstream bandwidth of OSS. Alibaba Cloud Content Delivery Network (CDN) provides higher bandwidth. If you use CDN to access OSS resources, CDN caches the resources on CDN nodes closest to your region and distributes the resources to you from the nodes. This way, you can access OSS resources more quickly at lower costs.

awskkwOption: A

The use of CDN is obviously the answer.

AAAAA CDN is the key

TMZtmzOption: A

A. OSS + CDN combination Explanation: OSS (Object Storage Service): Alibaba Cloud OSS is a scalable and secure object storage service. It is suitable for storing and retrieving large amounts of unstructured data, such as images. You can use OSS to store the 10GB of images and handle the additional 50GB of image content uploaded weekly. CDN (Content Delivery Network): CDN is used to accelerate the delivery of static content, such as images and JavaScript files, by caching them at various edge locations. This helps in reducing latency and improving the loading speed for users located around the world. CDN can be used in conjunction with OSS to improve the performance of delivering images and scripts to users. Therefore, the combination of OSS for storage and CDN for content delivery is a suitable solution to address both the storage and performance issues in this scenario.

one single ECS instance is used to host all the application content as well as a MySQL database. --- This should be separated.

ZZZ_SleepOption: A

A. OSS + CDN combination Combining OSS for scalable storage and CDN for efficient content delivery will address both the storage and performance issues while accommodating the growing user demands and image content. OSS (Object Storage Service): You can use OSS to store and manage the 10GB of existing images and the additional 50GB of image content that will be uploaded every week. OSS provides scalable, reliable, and cost-effective storage for large amounts of data, making it ideal for storing images. CDN (Content Delivery Network): CDN can significantly improve the performance of delivering images and other static assets to users. By caching these assets on CDN edge servers distributed globally, it reduces the load on your ECS instance and enhances the user experience by serving content from the nearest edge location. This helps in alleviating the slow loading of images and improves overall portal responsiveness.
