Microsoft Azure Service Fabric

Agenda • • • Service Fabric Introduction Concepts and terminology Service management life cycle Portal Fault Analysis service Monitoring and diagnostics

Why a microservices approach? • Build and operate a service at scale • Continually evolving applications • Faster delivery of features and capabilities to respond to customer expectations • Improved resource utilization to reduce costs

Monolithic application approach • A monolith app contains domain specific functionality and is normally divided by functional layers such as web, business and data • Scales by cloning the app on multiple servers/VMs/Containers App 1 Microservices application approach • A microservice application separates functionality into separate smaller services. • App 1 App 2 Scales out by deploying each service independently creating instances of these services across servers/VMs/containers

What is a microservice? Encapsulates a scenario Are developed by a small engineering team Can be written in any language and framework Contain code plus state that is independently versioned, deployed, and scaled § Interact with other microservices over well defined interfaces and protocols such as http § Have a unique name (URL) that can be resolved § Remains consistent and available in the presence of failures § §

Demo • Fault Analysis service & Resource balancing

Performance and stress response • Rich built-in metrics for Actors and Services programming models • Easy to add custom application performance metrics • we emit standard ETW events, you can use any tool of your choice to consume and visualize Health status monitoring • Built-in health reports for cluster and system services • Flexible and extensible health store for custom app health reporting • Allows continuous monitoring for real-time alerting on problems in production Business telemetry • Collect, analyze and drive insights from your customers’ interaction with your application • Allows data-driven decision making

Detailed System Optics • Repair suggestions. Examples: Slow Run. Async cancellations, Run. Async failures • All important events logged. Examples: App creation, deploy and upgrade records. All Actor method calls. • Detailed System events - Allow you to know what service fabric was doing at the time of the incident. Custom Application Tracing • ETW == Fast Industry Standard Logging Technology • Works across environments. Same code runs on devbox and also on production clusters on Azure. • Easy to add and system appends all the needed metadata such as node, app, service, and partition. Choice of Tools • • Visual Studio Diagnostics Events Viewer Windows Event Viewer Windows Azure Diagnostics + Operational Insights Easy to plug in your preferred tools: Kibana, Elastisearch and more
