Microsoft Azure Service Fabric Traditional vs Microservices approach
Traditional application approach
A traditional 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.
Microservices application approach
A microservice application separates functionality into separate smaller services.
Scales out by deploying each service independently creating instances of these services across servers/VMs/containers.

7. Microsoft Azure Service Fabric Service type
Services types are composed of code/config/data packages.
code packages define an entry point (dll or exe)
config packages define service specific config information
data packages define static resources (eg. images)
Packages can be independently versioned.
Service Type 1
Code
Config
Data
<ServiceManifest Name="QueueService" Version="1.0">
<ServiceTypes>
<StatefulServiceType ServiceTypeName="QueueServiceType" HasPersistedState="true" />
</ServiceTypes>
<CodePackage Name="Code" Version="1.0">
<EntryPoint>
<ExeHost>
<Program>ServiceHost.exe</Program>
</ExeHost>
</EntryPoint>
</CodePackage>
<ConfigPackage Name="Config" Version="1.0" />
<DataPackage Name="Data" Version="1.0" />
</ServiceManifest>

protected override async Task RunAsync(CancellationToken cancellationToke) {
    var requestQueue = await this.StateManager.GetOrAddAsync<IReliableQueue<CustomerRecord>>(“requests");
    var locationDictionary = await this.StateManager.GetOrAddAsync<IReliableDictionary<Guid, LocationInfo>>(“locs");
    var personDictionary = await this.StateManager.GetOrAddAsync<IReliableDictionary<Guid, Person>>(“ppl");
    var customerListDictionary = await this.StateManager.GetOrAddAsync<IReliableDictionary<Guid,object>>(“customers");
    while (true)
    {
        cancellationToke.ThrowIfCancellationRequested();
        Guid customerId = Guid.NewGuid();
        using (var tx = this.StateManager.CreateTransaction())
        {
            var customerRequestResult = await requestQueue.TryDequeueAsync(tx);
            await customerListDictionary.AddAsync(tx, customerId, new object());
            await personDictionary.AddAsync(tx, customerId, customerRequestResult.Value.person);
            await locationDictionary.AddAsync(tx, customerId, customerRequestResult.Value.locInfo);
            await tx.CommitAsync();
        }
    } }
