3. .NET Application Architecture
Available at dot.net/architecture
Prescriptive guidance for building Microservices, Web, Mobile and Windows applications.
eBooks accompanied by sample applications

4. Why develop for the cloud?
Agility
Better deployment stack
DevOps practices using continuous delivery
Growth Enablement
Lead Time for Expansion
Scalability
Insights and Analytics
Total cost
Infrastructure Cost
Ongoing Maintenance

5. Traditional App Design
Most functionality contained within a few processes made of libraries and separated by layers
Scales by cloning the entire app on new servers or VMs

6. Microservices
Segregate functionality into separate smaller services with well defined communication protocols (e.g. http, message buses, etc.)
Scale by deploying each service independently with multiple instances
Improve speed of iteration:
Changes only affect small areas of the application
Enables testing in isolation

7. Micro Service Design Separates functionality into separate services
Fine grained density of services
Each service is deployed and scaled independently

8. Secret Management
Application Secret: Data required by your application to access secured resources (e.g. database connection strings, API keys, etc.)
Frequently are different with different access levels across application deployment tiers (Dev, Test, Staging, Production)
Should not be stored in source code

10. Azure Diagnostics
See overall service health and which layers are failing
Automatic correlation of logs & exceptions across http calls
Snapshot Debugger
Code-level analysis of performance in production

12. Serverless Computing Event Driven
e.g. when an item is pushed into storage
Scales Indefinitely
Pay only for resources used during execution

Choosing Orchestrators in Azure
Azure Product
Orchestrator
Description
Good for
Common workloads
Azure Service Fabric is a distributed systems platform that makes it easy to package, deploy, and manage scalable and reliable microservices
Stateful svc & Actors
Microservices based on plain processes
Microservices based on containers
Docker Swarm is a clustering and scheduling tool for Docker containers. With Swarm, IT administrators and developers can establish and manage a cluster of Docker nodes as a single virtual system
Kubernetes is an open-source platform for automating deployment, scaling, and operations of application containers across clusters of hosts
As a datacenter operating system, DC/OS is itself a distributed system, a cluster manager and a container platform
Microservices based on containers (Including other Linux containers, not just Docker)
