AgendaChallenges in large distributed enterprise systemsMicro-introduction to microservicesMicrosoft Azure Service FabricActor pattern and programming modelWrapupQuestions and Answers

Challenges in large distributed systems• Architecture aligned to organization

and vice versa• Strict technology choices with

additional governance• Specialized teams per function• Monolithic structure from

evolutionary growth • Long test periods and big release

schedules• High risk big-bang deployments of

dependent systems• Hard to scale entire system or parts

Transitioning to a microservices architecture

The many definitions of microservices- Small and focused on doing one thing well- Autonomous

“Loosely coupled service oriented architecture with bounded contexts”Adrian Cockcroft (Netflix)

“SOA done right”Anonymous

“… services are independently deployable and scalable, each service also provides a firm module boundary, even allowing for different services to be written in different programming languages.”Martin Fowler (Thoughtworks)

• Organized by logical cohesion• Teams own layers spanning domains• Unified technology choice

From horizontal to verticalChange your architecture to vertical partitions

• Modeled after organization’s domains • Owned by team• Top to bottom• Isolated from each other as much as possible

Benefits

Heterogeneous technology landscape

Resilience against failure

Selective scaling

Deployment of smaller pieces with lower risk

Alignment with organization• Ownership with teams

Composability

Replaceability

Problems and solutions• Rolling upgrades• Availability guarantees• Scale out architecture• Resource governance• Density• Packaging and deployment• Policy enforcement• Granular versioning• Stateful workloads• Leader election

• Stateless Microservices:• Has no local persistent state • Optionally stores state in external data stores• Can have multiple instances for improving performance• E.g. Web API, Gateway Service, etc.

• Stateful Microservices:• Contains highly consistent local state• Provides redundancy through replication• Scale for performance, not for redundancy• E.g Databases, Workflows, etc.

• Existing apps written with other frameworks• node.js, Java VMs, any EXE

Reliable Services API Reliable Actors API

Reliable Actors• Actors are isolated single-threaded components that

encapsulate both state and behavior• Actor communicate with the system, including other

Actors, by sending asynchronous messages with a request/response pattern• Actors are virtual: there is no need to initialize or

destroy them

DEMO

Reliable Actors API

Summary• Microservices as a potential

architecture style• Adding complexity to gain simplicity• Choose an appropriate programming

model• Azure platform services help solve

remaining challenges for reliability and scaling
