Macrometa's architecture is a geo distributed event source with a materialized view engine and CRDT based replication. To achieve consistency in replication, Macrometa provides an adaptive model that allows developers to define the consistency level with fine grained granularity to achieve different levels of isolation and consistency depending on their needs.

Macrometa's team of scientists and engineers have incorporated leading edge ideas from distributed systems and concurrent databases that incorporate technologies like Conflict Free Replicated Datatypes (CRDT) to create a new highly secure, high performance, low latency data infrastructure.

Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. It's a fully managed, multi-region, multi-active, durable database with built-in security, backup and restore, and in-memory caching for internet-scale applications.

DynamoDB differs from other Amazon services by allowing developers to purchase a service based on throughput, rather than storage. If Auto Scaling is enabled, then the database will scale automatically. Additionally, administrators can request throughput changes and DynamoDB will spread the data and traffic over a number of servers using solid-state drives, allowing predictable performance.

To connect programmatically to an AWS service, you use an endpoint. In addition to the standard AWS endpoints, some AWS services offer FIPS endpoints in selected Regions.

Backups 
Charged separatedly from the project. Has three different options: Continuous backups, on-demand, or restoring a table.

Security
AWS is responsible for protecting the infrastructure that runs AWS services in the AWS Cloud. Includes data protection, identity and access management, infrastructure security, and more.

The Macrometa Global Data Network is based on cutting edge computer science incorporating new ideas and research in the areas of messaging, event processing, data consistency and replication.

Amazon DynamoDB is a NoSQL database that supports key-value and document data models. Developers can use DynamoDB to build modern, serverless applications that can start small and scale globally to support petabytes of data and tens of millions of read and write requests per second.

• Microsecond latency with DynamoDB Accelerator
  
• Automated global replication with global tables
  
• Read/write capacity modes
  
• On-demand mode
  
• ACID transactions
• Encryption at rest
  
• Point-in-time recovery
  
• On-demand backup and restore
