For a multitier web application that requires complex queries and table joins, along with the need for high availability, Amazon DynamoDB is the suitable service. Here’s why:

Support for Complex Queries: DynamoDB supports complex queries and table joins through its flexible data model and secondary indexes.

High Availability: DynamoDB is designed for high availability and durability, with data replicated across multiple AWS Availability Zones1.

Managed Service: As a fully managed service, DynamoDB requires minimal operational overhead, which is ideal for organizations with limited staff.

Scalability: It can handle large amounts of traffic and data, scaling up or down as needed to meet the demands of the application.

References:Amazon DynamoDB is a NoSQL database service that provides fast and predictable performance with seamless scalability. It is suitable for applications that require consistent, single-digit millisecond latency at any scale1. It’s a fully managed, multi-region, durable database with built-in security, backup and restore, and in-memory caching for internet-scale applications1.

Disaster Recovery as a Service (DRaaS): DRaaS is a third-party service that provides organizations with a secondary site infrastructure, which employs cloud computing for application and data recovery from synchronous or asynchronous replication1.

Fault Tolerance and Redundancy: A fault-tolerant disaster recovery site with fully redundant equipment ensures that all critical systems and components have backups ready to take over in case of failure1.

Real-Time Data Synchronization: This feature ensures that data is continuously mirrored to the disaster recovery site, allowing for real-time recovery and zero data loss during failover1.

Hot Site: A hot site is a fully operational offsite data center equipped with hardware and software, network connectivity, and real-time data synchronization. It is ready to assume operation at a moment’s notice, which aligns with the description provided1.

Minimal Downtime: The use of a hot site allows for minimal downtime during a disaster, as the site is already running and can take over immediately without the need to set up or configure equipment1.

Flexential’s explanation of Disaster Recovery as a Service (DRaaS)1.

The description provided indicates that the disaster recovery site is a Warm Site. Here’s why:

Partially Redundant Equipment: Warm sites are equipped with some of the system hardware, software, telecommunications, and power sources.

Data Synchronization: They have provisions for daily or weekly data synchronization, which aligns with the description given.

Failover Time: Failover to a warm site typically occurs within hours or days, as mentioned.

Minimum Data Loss: Due to the regular synchronization, there is minimal data loss in the event of a failover.

References:A Warm Site is a type of disaster recovery site that sits between a hot site, which is fully equipped and ready to take over immediately, and a cold site, which is an empty data center that requires setup before use. The warm site’s readiness and partial redundancy make it suitable for organizations that need a balance between cost and downtime.
