The document discusses modern application paradigms and databases, focusing on topics like Database-as-a-Service (DBaaS), Backend-as-a-Service (BaaS), NoSQL, and serverless databases. It addresses key considerations such as ease of operations, potential vendor lock-in, and the impact on application development. Additionally, it explores concepts like microservices and event-driven architectures, including the implications of service database ownership and reporting.

1. Discussion: Modern
Application Paradigms and
Databases
Thomas Boyd
Director, Technical Marketing
MariaDB Corporation

2. Agenda
● DBaaS, MBaaS & BaaS
● DSL, DASLs, DAOs, & ORMs
● NoSQL
● Serverless and “ Serverless” Databases
● Microservices & Event Driven
Audience Participation Required!

3. Database-as-a-Service (DBaaS)
● Ease of Operations
● No impact on App Development?
○ Is DBaaS offering current release with all capabilities
■ Temporal Data
■ Advanced Analytics Functions
■ Full MariaDB Platform
○ Will configuration options (scale, performance, HA, DR) impact development

4. (Mobile) Backend-as-a-Service (MBaaS, BaaS)
● Integrated Services
○ Data/Database
○ Authentication and Authorization
○ Files
○ Streaming
● Beware Vendor Lock-in
○ Parse
○ Firebase
○ Others….

5. DSL, DASLs, DAOs, ORMs
● “Modern”?
● Isolation of concerns
● When to break away from ORMs?
● Sharing definitions with others parts of stack or other applications
○ Google protobufs
○ Others?

6. NoSQL
● Agility, Flexibility, and Schema-less Databases
○ Preferred access patterns
○ Storage overhead
● ACID Transaction Support
● Scalability and “Big Data”
● Reporting and Analytics
○ MongoDB Aggregation Pipeline
● “Native” JSON support & MEAN Stack
○ MariaDB JSON Support

7. Serverless
● Elasticity
● Execution Environments (languages)
● Persisting Data
○ Queues
○ Databases
○ Caches

8. Serverless Databases?
● Elastic/Autoscaling
● Pausable
● Latency impacts?

9. Microservices & Event Driven Systems
● Does each services really need its own database?
● What about reporting across services?
