7. Service Fabric Cluster
Build 2015
4/25/2017
Service Fabric Cluster
A set of machines that Service Fabric stitches together to form a cluster
Clusters can scale to
1000s of machines
There are two important concepts to understand with Service Fabric
First you create a pool of machines called a Service Fabric cluster. This can start as small as 3 machines and grow to thousands of machines. It is fully elastic, and with no single point of failure.
This cluster of physical or virtual machines can be heterogeneous, some small, some large as well. In Azure the clusters can be deployed across availability sets and across regions for redundancy. These are VMs that you own, joined by a VNET and stitched together to form a scalable cluster.
Second you build applications that are composed of discrete microservices by writing code. Then you simply tell Service Fabric through a declarative model to deploy these service across the cluster Service Fabric determines the best place to insatiate and run them, based on the available machine resources. You can create multiple copies of the same application instance and you can reuse microservice across difference applications.
This is application and service orchestration achieving unparalleled levels of density and control at the APPLICATION level. The services are placed into containers, processes today and Windows Containers when they are available for resource and security isolation. Note; this is not simply about moving containers around, this is understand how to manage the microservices within those containers which is actually the code you as a developer write.

11. So…, what is a microservice?
Build 2015
4/25/ :46 PM
So…, what is a microservice?
(Is logic + state that is) independently versioned, deployed, and scaled
Has a unique name that can be resolved
e.g. fabric:/myapplication/myservice
Interacts with other microservices over well defined interfaces and protocols like REST
Remains always logically consistent in the presence of failures
Hosted inside a “container” (code + config)

12. What can you build with Service Fabric?
4/25/ :46 PM
What can you build with Service Fabric?
Stateless applications
A service that has state where the state is persisted to external storage, such as Azure databases or Azure storage
e.g. Existing web (ASP.NET) and worker role applications
Stateful applications
Reliability of state through replication and local persistence
Reduces latency
Reduces the complexity and number of components in traditional three tier architecture
Existing apps written with other frameworks
node.js, Java VMs, any EXE
