Reliability and resiliency are of great importance when building and designing service. In many organizations, REST APIs are used to onboard IoT devices and help them devices stay connected to the Wi-Fi. This is a service that needs the highest uptime possible.

What is Active-Active Architecture?

An active/active system is a network of individual processing nodes, each of them having access to a replicated database so that all nodes can participate in a shared application.

Why are we going multi-region?

  • Improved latency and performance

  • Complying to data storage needs

  • Enable regional failover

AWS has a classy, global network with high-speed and redundancy connectivity across a range of availability zones and regions. An enterprise can use these wide-ranging global networks to build a distributed application architecture and reach an international audience.

Advantages of Multi-Region Active-Active Architecture

AWS multi-region architectures take advantage of enterprises in several crucial ways. First, they are always active-active configurations and function simultaneously in more than two regions. This distributed method can boost business continuity with high availability and resiliency for critical workloads and extend the risk between geographically isolated regions.

Second, AWS multi-region architectures can enhance the user experience (UX) and boost application performance. They bring users closer to the application to solve possible disruptions and latency that occur when users access an application from a distance.

Third, each region can hold its own unique data set, as they can make the process complicated with data replication and integration, but the isolation enables businesses to observe data retention and protection practices.

However, a distributed application architecture does not come easy, and implementation may involve subject experts, and IT teams need to plan carefully and consider numerous complex issues.

Key AWS Services

The below are few of the key AWS services that can be leveraged to achieve Multi-Region Active-Active Architecture:

  • Route 53

  • CloudFront

  • AWS Aurora Global Database

  • AWS Elasticsearch (ES)

  • AWS Elastic Container Service (ECS)

  • AWS Elastic Container Registry (ECR)

  • AWS Fargate

In addition, a global solution will benefit through the following services:

  • AWS Shield– Managed Distributed Denial of Service and protection service
  • Elastic Logstash Kibana (ELK) StackELK stack is used to extract logs for issue analysis from different services in one central place
  • AWS CloudTrail– Allows governance, risk auditing, compliance, and operational auditing of your AWS account
  • AWS ElastiCache– Used to offload traffic from your RDS Aurora DB or Elasticsearch cluster.

Summary

Multi-region active-active architectures are expensive to create and maintain but are vital if your app requires low latency for your users worldwide. This is a Tier 1 app with 99.99% demand for availability and requires built-in disaster recovery capability across regions.
