AWS re:Invent 2017: How to Design a Multi-Region Active-Active Architecture (ARC319)

Many customers want a disaster recovery environment, and they want to use this environment daily and know that it's in sync with and can support a production workload. This leads them to an active-active architecture. In other cases, users like Netflix and Lyft are distributed over large geographies. In these cases, multi-region active-active deployments are not optional. Designing these architectures is more complicated than it appears, as data being generated at one end needs to be synced with data at the other end. There are also consistency issues to consider. One needs to make trade-off decisions on cost, performance, and consistency. Further complicating matters is the variety of data stores used in the architecture results in a variety replication methods. In this session, we explore how to design an active-active multi-region architecture using AWS services, including Amazon Route 53, Amazon RDS multi-region replication, AWS DMS, and Amazon DynamoDB Streams. We discuss the challenges, trade-offs, and solutions.

"Don't worry about hard decisions, both options are probably equally good, worry about the easy decisions, as one of them is clearly better than the other". That's brilliant! I really liked it.

Backup & Restore (Data backed up and restored)
Pilot Light (Only Minimal critical functionalities)
Warm Standby (Fully Functional Scaled down version)
Multi-Site (Active-Active)

Very good.

pretty cool :D

For code synchronization, rolling canary deployment at 17:32 How exactly does this work?

44:00 Each master has a standby that is Synchronously replicated? Only the region A has that. Other regions have read replicas getting data copied from region A. Do the other regions have a standby?(as per what is being spoken) OR do they only have a read replica?(as shown in the figure). Please advise. thanks

Recommendation: start at 11:47

Agree. But I see this comment only after viewing entire video. lol
