You have developed a web-based recommender system. The application is deployed in the Cape Town region. Within the first few months, your application attracts thousands of new users daily. You now want to expand to Australia. How can you successfully serve the Australian market whilst ensuring high availability and low latency?Add more Availability Zones in Cape Town.Deploy your application in the Sydney region.Deploy your application in Multiple Availability Zones in the Cape Town Region.Provision more resources.

To successfully serve the Australian market while ensuring high availability and low latency, you should consider the following steps:

1. Deploy your application in the Sydney region: AWS has a region in Sydney, Australia. By deploying your application in this region, you can reduce latency for your Australian users as the data wouldn't have to travel as far to reach them. This can significantly improve the performance of your application for users in Australia.

2. Use Multiple Availability Zones: To ensure high availability, you should deploy your application across multiple Availability Zones within the Sydney region. Availability Zones are essentially separate data centers. If one goes down, your application will still be available in the other zones. This can significantly increase the reliability of your application.

3. Auto Scaling: To handle the increase in traffic, consider implementing an auto-scaling solution. This will allow your application to automatically scale up to meet demand during peak times and scale down during quieter periods. This not only ensures that your application can handle the traffic but also helps to manage costs as you're only using the resources you need.

4. Load Balancing: Implement a load balancer to distribute incoming application traffic across multiple targets, such as EC2 instances, in multiple Availability Zones. This increases the availability of your application. You can add and remove compute resources from your load balancer as your needs change, without disrupting the overall flow of requests to your application.

5. Content Delivery Network (CDN): Consider using a CDN like Amazon CloudFront to cache your content closer to your users. This can further reduce latency and improve the performance of your application for users in Australia.

6. Data Replication: If your application uses a database, consider replicating this data in the Sydney region. This will ensure that your Australian users can quickly access the data they need.

By following these steps, you can ensure that your web-based recommender system can successfully serve the Australian market with high availability and low latency.
