TD Role: Architect Solution / Architect Functionnel / Technical Lead (architecture applicative)

Monoliths and Microservices

Monoliths : Single-tiered software, combining modules into a single program.
- Benefits: Easy Deployment, Managed Complexity, Low Dependency
- Limitations: Expensive Scalability, Low Update Frequency, Issues with Rollbacks
Microservices : Implement discrete functionalities, each being a mini-application.
- Properties: Modularity (specific business functions), Autonomy (independent development and deployment), Data Decentralization (each microservice typically has its own database).
- Benefits: Scalability, Faster Development, Fault Isoliation

CI/CD and DevOps

CI/CD (Continuous Integration/Continuous Deployment) and DevOps:
Key stages: plan, design, development, feedback, release, test, deploy and operate
Tools frequently used with DevOps, and CI/CD Jenkins, Bitrise, Kubernetes, Docker, Github, SonarQube

Logging

Importance: Crucial for diagnostics and problem resolution.
Tools: Centralized tools like ELK Stack (Elasticsearch, Logstash, Kibana) are frequently used.

Monitoring

Importance: Real-time observability for performance tracking and issue detection.
Tools: Grafana, Splunk are used for dashboards, visualization and analysis.
Metrics: Essential for performance monitoring. Examples: CPU usage, memory usage, traffic rates.

Cloud Computing (Public, Private, Hybrid)

Public Cloud: Services provided by a third-party provider, typically on a pay-per-use basis.
Private Cloud: A dedicated cloud environment controlled by a single organization.
Hybrid Cloud: A combination of on-premises and cloud environments for flexibility.
IaaS, PaaS, SaaS: Different cloud service models (Infrastructure as a Service, Platform as a Service, Software as a Service).

Differences between Non-Cloud & Cloud Projects

Non-Cloud (Pets): Unique, highly specific, and well-maintained.
Cloud (Cattle): Many instances, standardized, easily replaced.

Liabilities (Cloud vs. Client)

Customer Responsibility: Security in the cloud (client-side data encryption, authentication procedures)
Cloud Provider Responsibility: Security of the cloud (infrastructure, platform, network)

Security

Authentication: Verifying a user's identity (e.g., using passwords).
Authorization: Determining a user's permissions (e.g., access to particular resources).
SSO (Single Sign-On): Enables single login for multiple applications.
OAuth, OIDC: Authorization standards that enable third-party applications to access user data without exposing credentials.

Patterns (e.g. OAuth & OIDC).

OAuth, OIDC use cases: Secure access, protect user’s data, implement single sign-ons.

Microservice-Design: Design Patterns and implementation steps to create microservices :

Event broker Pattern : (asynchronous communication between producer and consumers; decoupled components).
Retry pattern - strategy for when a client or service fails to respond within a timeout
Circuit breaker pattern – stops a broken or unstable service to avoid cascading failures.

Key takeaways for future learning:

There is an emphasis on data visualization and analysis (dashboarding).
The shared language use is a key concept.
