3 Microservices Architecture

5. Modelled around business domain : Separate system
capability into different domains and its associated logic.
Culture of Automation : Follow DevOps for continues
integration and continuous delivery.
Hide implementation details : It helps to do changes &
improvement without affecting the overall architecture.
Decentralization : No centralized database, usually
each service is designed to manage its own database.
Deploy Independently : Each service can be deployed
independently.
Failure Isolation: A microservices failure impact that
service & its associates. Others services keep running.
Highly Observable : Collect enough information about
a microservice to analyze what is happening within each
of them like log events and stats.

8. Swipe
Learn the benefits of Docker and containerization.
Practice Docker CLI commands, Configure Docker
Compose and Docker Swarm.
Know Built-in containerization feature from .NET 7
and above (you no longer need a Dockerfile).
Learn Multi-Stage Docker Builds, Networking and
Volumes.
Practice to build and publish docker image to docker
registry like DockerHub or ACR and run the container
by pulling image from registry.
Have an understanding of Kubernetes fundamentals
and kubectl commands.
Practice to run docker image locally k8s cluster or on
Cloud based k8s cluster like AKS, EKS or GKE.

9. Swipe
Service discovery is crucial in a microservices architecture
for enabling dynamic and efficient communication between
services.
Consul: includes features for service discovery, service
mesh networking, health checking, and key-value
storage.
Eureka: provides a RESTful interface for service
registration.
Kubernetes Service Discovery: allow services to
discover and communicate with each other using DNS-
based service names.

10. Swipe
Message broker serves as a central communication hub
for facilitating asynchronous communication between
microservices through the use of events.
Choose a suitable event broker or messaging
middleware for your microservices architecture, such as:
Apache Kafka
RabbitMQ
Amazon Kinesis
Azure Service Bus
Consider factors like scalability, durability, latency,
ordering guarantees, and integration capabilities.

11. Swipe
Implementing monitoring and logging is crucial for
maintaining the health, performance, and reliability of
microservices-based systems.
Learn about the importance of monitoring and logging
in distributed systems.
Understand the differences between monitoring (real-
time observation of system metrics) and logging
(capturing and storing application events and errors).
Explore different monitoring and logging tools and
platforms, such as:
OpenTelemetry
Grafana
ELK stack (Elasticsearch, Logstash, Kibana).

Know Cloud to quickly provision, configure, and deploy
.NET based applications.
The most popular clouds are Azure, AWS and GCP.
Start with Azure to learn IaaS services (VM, Storage,
Networking) and PaaS services (WebApp, Functions,
Azure SQL, Cosmos DB, APIM) and security,
management using KeyVault and Azure Entra ID.
Cloud Fundamentals are same everywhere. So later on
you can learn AWS or GCP.
Master to build and secure .NET-based application
with various Azure/AWS services.
Get yourself Microsoft/Amazon/Google Certified
Developer or Solution Architect.

Familiarize yourself with built-in security features in
.NET, Frontend and Cloud including code access
security, role-based security, and encryption APIs.
Know how to implement various authentication
methods like OAuth, OpenID Connect.
Learn to write secure code to prevent common
vulnerabilities like SQL injection, cross-site scripting
(XSS), and cross-site request forgery (CSRF) in .NET.
Understand how to use HTTPS, SSL/TLS, and other
protocols to secure communication in .NET applications.
Secure Web APIs in .NET, including token-based
authentication and rate limiting.
Use tools like OWASP ZAP or Burp Suite for
vulnerability scanning and penetration testing.

Health Management System: Include aspects such as
appointment scheduling, electronic health records
(EHR), billing. Each microservice can specialize in
domains like appointment, patient information, and
notifications for scalability and maintainability.
Retail Inventory and Order Management System:
Microservices can handle aspects like inventory
tracking, order routing, and payment processing, and
integrating with third-party services.
Financial Services Platform: Each microservice
manages specific financial operations. For instance, one
microservice handles account management while
another deals with transaction processing and fraud
detection.
eShopOnContainers: The application simulates an e-
commerce platform with features like product catalog,
shopping cart, and order and payment processing.
