How do I scale my Data linearly?Does the VM have the required resources?
Are there any cold VMs that I shouldn't be paying for?
How do I move a service?
Is the VM running?Is the VM too hot?How do I deploy across a part of the cluster?
Does the VM have the required capacity?
How do I roll back a deployment if it is does not work?
How do I deploy across a part of the cluster?
Can I have multiple versions running side-by-side?
Where should I move it?
Does my data have a single point of failure?Is my application running?
Can I replicate data across data centers?

Achieving High Density with Azure Service Fabric
IaaS Approach 1 Cluster – 1 VM
Azure Service Fabric(Stateless, stateful or Actor services)
• 1 service instance per VM with uneven workloads
• Lower compute density
• Slow in deployment & upgrades
• Slower in scaling and disaster recovery
• Many microservices per VM
• High microservices density
• Fast deployment & upgrades
• Fast scaling microservices across the cluster
Placement Constraints
You control your topology

N2DMZ = True
N4DMZ = True
N5DMZ = True
N6DMZ = False
N3DMZ = False
Constraints = “(DMZ == False)”
Constraints = “(DMZ == True)”

Scaling and Balancing
• Declarative Model – “I want the topology to look like this”
• Service Fabric does the work• Balances Resources
• Moves services when hot
• Respects constraints
• You provide guidance• These metrics are important
• CPU
• Memory
• Etc.
• Balancing Threshold
• Activity Threshold
