Question

What are the two options to distribute data to millions of users around the world and which one is better in terms of services and scalability?

Answer 1

There are two main options for the given scenario:

1. Azure Cosmos DB

It is a database service that offers low latency and high availability. The scalability and elastic property of throughput makes it a well defined option for data consistent applications. When the application needs critical and on time response across the globe, this option is the best. It also offers 24/7 online facility and unlimited storage.

2. Google Cloud Spanner

This is a relational DB by Google and is scalable with synchronously replicated and globally distributed property. It is also multi-version and externally consistent. It offers high scalability, availability, and reliability in distributed transactions. It also powers Google's other properties, such Google apps, AdWords, etc.

They both have their own pros and cons. However, in terms of scalability and services Google Cloud Spanner is the best. It offers working with Bigtable which is unmatched when it comes to performance.
