Architecture types - Tier layers

Understanding Distributive Systems

• Presentation Tier

• Application Tier.

• Data Tier.

Architecture types - Multi Tier

Understanding Distributive Systems

Multi-tier architectures consider additional layers, such as a web tier which hosts servlet containers and a web server and which is located between client tier and application tier.

CAP Theorem

Understanding Distributive Systems

• Consistency.

• Availability.
• Network Partitioning.

During the time of Network Partitioning we could only achieve Consistency OR Availability at a moment

Discussing Architecture Types - Codebase/Deployment Management

Understanding Distributive Systems

• Monolith.
  

• Micro services.
• Mono repos

Our Vision is to take Sastaticket Architecture towards mono repos

Common Deployment types

Understanding Distributive Systems

• Deployment with down time.
  

• Deployment with 0 down time.

Blue-Green Deployment

Understanding Distributive Systems

Blue-green deployments involve running two versions of an application at the same time and moving traffic from the in-production version (the green version) to the newer version (the blue version). You can use a rolling strategy or switch services in a route.

Crisis Management - Rolling strategies

Understanding Distributive Systems

• Roll forward

• Roll backward
