Azure Resource Manager

•  Application Lifecycle Container •  Declarative Solution for

Deployment and Configuration •  Consistent Management Layer

Azure Resource Manager

Azure Resource Groups

•  Tightly coupled containers of multiple resources of similar or different types

•  Resource Group is a unit of management

–  Deployment, Update, Delete –  Identity –  Metering, billing, quota

Azure Templates can: •  Ensure Idempotency

•  Simplify Orchestration

•  Simplify Roll-back

•  Provide Cross-Resource Configuration and Update Support

Azure Templates are: •  Source file, checked-in

•  Specifies resources and dependencies (VMs, WebSites, DBs) and connections (config, LB sets)

•  Parameterized input/output

Virtual machine building blocks

•  OS & data disk images –  Various sizes –  Windows base OSs –  Linux base OSs –  Azure Certified Images –  Community images

•  VM Extensions –  Security –  Deployment –  Configuration –  Others

•  Visual Studio debuggers •  Diagnostics agents •  Monitoring agents •  Access recovery •  Docker extension •  Backup helper

Demo virtual machines

Challenges of scale with virtual machines •  Need to correlate loops of independent resources, e.g. NICs,

storage accounts, VMs –  Different loop sizes for NICs and storage accounts etc.

•  No easy mechanism to scale in •  Scale out – How do you ensure availability •  Resource loops are a syntactical shorthand, but multiple calls go to

fabric

…….Virtual Machine Scale Sets to the rescue

What are Virtual Machine Scale Sets?

•  A way to deploy and manage a set of identical VMs •  Integrate with Azure Autoscale

•  Integrate with Azure Load Balancer

•  An Azure Compute resource Microsoft.Compute/virtualMachineScaleSets

•  Scalable compute layer for hyperscale apps

•  An infrastructure for PaaS

VM Scale Sets in ARM

•  Auto-Scalable •  Fast •  Customizable

–  Windows or Linux –  VM extensions –  Open PaaS platform

•  Ease of Management

–  Focus on target instance count

–  Updateable

Demo container service

•  Scales by cloning the app on multiple servers/VMs/Containers

Monolithic application approach 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

•  A monolithic application has most of its functionality within a single process that is commonly componentized with libraries.

App 1 App 2 App 1

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

Types of microservices from a Service Fabric perspective

•  Stateless microservice –  Has either no state or it can be retrieved from an external store –  There can be N instances –  e.g. web frontends, protocol gateways, Azure Cloud Services etc.

•  Stateful microservice –  Maintain hard, authoritative state –  N consistent copies achieved through replication and local persistence –  e.g. database, documents, workflow, user profile, shopping cart etc.
