Discover the essentials of optimizing Serverless Framework applications for a global audience with multi-region deployments with StratusGrid’s enhancements.
Until recently, deploying your Serverless Framework application in multiple regions was a somewhat difficult process involving a lot of custom CloudFormation. However, StratusGrid recently submitted changes to serverless-domain-manager that make it much simpler.
The following architecture can be created with simple configuration changes:
Serverless Framework deployments are generally created in a single region in Amazon Web Services (AWS). This may work if you are only targeting a single part of the world, but if your application is intended for a global audience, your response time can be unacceptably long for users who are far away from your deployment region. A multi-region deployment with latency-based routing can reduce response times from multiple seconds to double-digit milliseconds!
Multi-region deployments are also great from a disaster recovery and redundancy perspective. Automated health checks and a failover policy can be configured to achieve an active-active setup that can fail over between regions in the event of any issue.
This is particularly useful for situations such as the us-east-1 outage on December 7, 2021 , where services were unavailable for nearly 8 hours in us-east-1, while other regions remained unaffected.
Lambdas are well suited for multi-region deployments because they can easily scale and adapt to varying traffic patterns without incurring unnecessary costs. Operating within the pay-as-you-go model makes them much more economically appealing than other computing options - they can result in wasted and idle resources.
At StratusGrid, we use the popular (and excellent) plug-in serverless-domain-manager to create the custom domain and Route 53 records. We recently submitted a change to the repository that makes it possible to perform multi-region deployments with minimal configuration changes.
To get started, add the serverless-domain-manager configuration to your `serverless.yaml` file as usual. The only difference is that you now add a `route53Params` structure with a `routingPolicy: latency` property.
Then update your deployment process to deploy to multiple regions:
Example
Check out this github repository for an example of a multi-region project.
We can demonstrate latency reductions by creating a simple lambda from the demo repository and deploying it to a single region. In this case, I deployed it to ap-southeast-1, which is far away from my machine located in the eastern United States. Making 10 requests I get the following total response times in seconds:
Deploying the same project again in us-east-1, I get these response times with the exact same domain:
Deploying your Serverless Framework applications in multiple regions is a cost-effective and easy way to improve your users’ experience while increasing your application’s resiliency. We encourage you to consider this pattern for all of your Serverless deployments.
