This model isno longer relevant
This model isbroken
Workloads are increasingly virtualized.
This includes perimeter network workloads.
Assumes people “inside” the perimeter always have the
organisation’s best interests in mind
When servers were serversand virtualization was something
that happened on mainframes
Model worked in the 90’s
Assumes that computers and devices inside the perimeter have
not been compromised

(Almost) assumes an “on prem” model of critical infrastructure
deployment
Also not relevant as more resources are being moved into
the cloud
Domain Isolation Policies
What was the goal of perimeter networks?
To host services that require exposure to the Internet and the
internal network
(Bastion Hosts)
Typical perimeter network workloads:• Proxy services
• Email gateway• Websites
• DNS• Remote access• Appliances
Hosts usually have public IP addresses
(unless NAT shenanigans)
Can’t virtualize everything (yet)
If you can’t virtualize it, you can’t move it to Azure
Significant savings in migrating workloads off perimeter network
into Azure
Not just about money:Simplify deploymentIncreased security
Increased availabilityEasy access to public IP address
Don’t have to migrate everything
to save money
First: Assess Perimeter Network Workloads
Easy to migrate
• Web sites / applications
• Email gateway• DNS
Difficult to migrate:
• Remote Access • Appliances• Proxy Servers

Azure
Manual Migration• Upload VHDs to Azure• Build workload in Azure and migrate
data
Automate Migration:Microsoft Migration Accelerator
for Azure
Can migrate the following to Azure:
• Physically deployed computers• VMware• Hyper-V• AWS
Automated migration:
• Automatically discover workloads from cloud
• Auto-provisioned target Azure VMs• Validate migrated workload in cloud
before cutover
Supports multi-tier applications
• Automatically migrate multi-tier production systems with application level consistency orchestrated across tiers
• Application startup order kept in place without requiring special configuration
Can discover Microsoft workloads
• Exchange• SQL Server• File Server• SharePoint• IIS
Use continuous replication to minimize cutover period
• MA for Azure supports full system replication including OS and application data
• Continuous replication and in-memory change tracking reduces cutover to minutes rather than hours
Migration Profiler
• Helps determine the size, activity and performance requirements of workloads
• Ensures correct Azure templates are being used prior to migration
• Monitors change rates, replication differential, asset health and more.

Deploying Migration Accelerator
1. Azure account2. Sign up for MA Preview3. Receive MA Portal URL, User ID & Password4. Install Configuration Server in Azure VM5. Install Master Target in Azure VM6. Install Process Server on-prem7. Register MA Account to Azure account8. Start on-prem resource discovery
• R
The Future• Virtual appliances designed for Hyper-V,
VMware, and AWS deployable to Azure• More roles supported in Azure
