To ensure that game assets are fetched from the closest region and have a fallback option in case the assets become unavailable in the closest region, a solution architect should leverage Amazon CloudFront, a global content delivery network (CDN) service. By creating an Amazon CloudFront distribution and setting up origin groups, the architect can specify multiple origins (in this case, the Application Load Balancers in each region). The primary origin will serve content under normal circumstances, and if the content becomes unavailable, CloudFront will automatically switch to the secondary origin. This approach not only meets the requirement of regional proximity and redundancy but also optimizes latency and enhances the gaming experience by serving assets from the nearest geographical location to the end-user.

References: AWS Documentation on Amazon CloudFront and origin groups provides detailed instructions on setting up distributions with multiple origins for high availability and performance optimization. Additionally, AWS whitepapers and best practices on content delivery and global applications offer insights into effectively utilizing CloudFront and other AWS services to achieve low latency and high availability.

This solution will meet the requirements of implementing a highly available architecture for the application servers in AWS. Creating a pool of ENIs will allow the application servers to have consistent MAC addresses, which are needed for the license files. Requesting license files from the vendor for the pool and storing them in Amazon S3 will ensure that the license files are available and secure. Creating a bootstrap automation script to download a license file and attach the corresponding ENI to an EC2 instance will automate the process of launching new application servers with valid licenses. Editing the bootstrap automation script to read the database server IP address from the AWS Systems Manager Parameter Store and inject the value into the local configuration files will enable the application servers to access the database without hard-coding the IP address in the configuration files. This will also allow changing the database server IP address without modifying the configuration files on each application server.

Hosting the .NET Core components on Amazon ECS with the Amazon EC2 launch type will meet the requirements of having complex orchestration and full control over networking and host configuration. Amazon ECS is a fully managed container orchestration service that supports both AWS Fargate and Amazon EC2 as launch types. The Amazon EC2 launch type allows users to choose their own EC2 instances, configure their own networking settings, and access their own host operating systems. Hosting the database on Amazon Aurora MySQL Serverless v2 will meet the requirements of having a strongly relational database model and using the same database engine as SQL Server. MySQL is a compatible relational database engine with SQL Server, and it can support most of the legacy application’s database model. Amazon Aurora MySQL Serverless v2 is a serverless version of Amazon Aurora MySQL that can scale up and down automatically based on demand. Using Amazon SQS for asynchronous messaging will meet the requirements of providing a compatible replacement for MSMQ, which is a queue-based messaging system3. Amazon SQS is a fully managed message queuing service that enables decoupled and scalable microservices, distributed systems, and serverless applications.
