XTX. ("Connecting the world by innovative technology ") was founded in 2014, is a semiconductor chip design high-tech enterprise. The company passed the ISO 9001 quality management system certification in 2015, in 2017 it was recognized as a national high-tech enterprise. The same year they obtained a deep venture capital investment of around 60 million yuan. In 2018, we will complete the financing of 410 million RMB in round B and B+ round led by Sequoia Capital China Fund and B-round led by China Investment Ventures. The company's product planning not only covers the mature storage technology route but also completes the future of the new memory multipoint layout. Currently, mass-produced products include SPI NOR Flash, NOR MCP, SPI NAND Flash, SD NAND Flash, NAND MCP, etc., mainly used in the Internet of Things, display and touch, communications, consumer electronics, industry, and other fields. Pain-point: Today's services are built-in native data centers, and service SLA can no longer be met as the business grows, and if data center failures can severely impact existing businesses, expect a disaster recovery solution.
The local data center regularly uploads the specified data to Ningxia's S3 and guarantees the integrity and availability of the data.

Agilewing is AWS's largest partner in China to complete migration projects and has helped dozens of large/listed enterprise customers complete AWS migration tasks. With deep work on AWS technology, Agile Cloud has earned AWS Oracle Competency Certification and AWS MSP Certification and became an AWS Core Partner in October 2018. The technical team is focused on the service capabilities development of AWS and is up to the task of testing this POC. Help customers complete testing deployments, and simulate the data center's network environment and system architecture, select appropriate test data, clarify file retention rules, write scripts for data uploads and check script details with households, and verify data integrity and consistency, and demonstrate test processes and results on-site.

Chengdu Lejin Technology

Chengdu Lejin Technology is a major focus on the entertainment industry start-ups. The main research and development/operation of the project is CC, a net-earning short video (UGC) plus leisure games aggregation app]. Their main customer groups are Southeast Asia, South America, North America, and Europe. Currently, the daily users are around 3 million. CDN was originally made using a product provided by GCP. With the growth of the business, Lejin found that GCP can not provide stable CDN services as the users in some countries' download failure rate is high, and in some countries GCP CDN is blocked. GCP's support needs for Lejin are also not responding effectively and quickly. After technical validation and business negotiations, Lejin decided to move the CDN business as a whole to AWS CloudFront.
Pain-point: At present, Lejin found that GCP can not provide a stable CDN service, users in some countries' download failure rate is high, while in some countries GCP CDN is blocked. GCP's support needs for Lejin were not responding effectively and quickly, so Lejin decided to use AWS CloudFront service.
1) Verify that AWS CDN cross-accounts can work normally.
2) Verify that the Data Replication Hub tool meets the customer scenario requirements when GCS is the source.
3) Verify the feasibility of the gsutil tool used in EC2.
4) Given that the Data Replication Hub tool has some compatibility issues in GCS, you need to write a replication script as an alternative to ensure successful testing.

The testing of the Data Replication Hub and gsutil tools is required, and the test architecture is described below:
1) Within AWS, deploy the Data Replication Hub tool through CloudFormation, and then start the task of copying GCS to S3 in the UI interface
2) Deploy the gcloud environment in AWS EC2 and use the gsutil tool to copy the GCS file to S3

Amazon CloudFront supports real-time monitoring, secure delivery of low-latency video, and supports Lejin's existing processing software. Multiple AWS services used by this solution work seamlessly together. Pull the content delivery network out of a single centralized site and distribute it closer to the audience. Agilewing helps customers seamlessly switch to AWS Cloudfront by helping them complete cache policies, the configuration of source request policies, testing of back-source policies, and cross-domain testing.
