Replicating Data to Support Multi-Region Applications

Replicating Data to Support Multi-Region Applications

In the previous article, we covered multi-region scaling, its importance, and how you can use Pulumi stacks to represent multiple regions and environments. The big takeaway from that article is that scaling your application across multiple regions is an important architectural decision to enable scalability and availability, but it comes with its own set of considerations. One of these considerations is around the data that your application needs or uses. Data replication is typically necessary in multi-region architectures because if you have multiple application instances worldwide making calls to just one database instance, the latency of your application will be high. After all, it will take a long time for that database instance to perform data operations and send back a result to the user through the application. Some requests might have repeated timeouts. In this article, we will cover data replication in multi-region applications and how it plays a pivotal role in distributed systems.

Scaling Applications Across Multiple Regions

Scaling Applications Across Multiple Regions

As a team building a distributed cloud service that will be used by different people around the world, you will need strategies to cater to users globally, ensuring uninterrupted service even in the face of disruptions. Have you ever wondered how businesses operate and deliver high-level performance across different regions? Well, that is the result of scaling applications across multiple regions — in a bid to ensure constant access and flexibility, organizations distribute their applications and databases across various geographic regions so that if one part faces issues, the service remains available elsewhere.
