create your Cloud Operating Model
2. Assess your
current environment
3. Migrate it
(using Azure Migrate free tool)
4. Optimize your
utilization
5. Secure and
Manage it
The Assess phase includes three steps:

Azure Migration Strategy
The Azure cloud migration strategy will cover the following
areas:
·
Azure Resource Manager (ARM) model to support effective
security, policy/compliance enablement and cost attribution
·
Rightsizing of the cloud infrastructure based on collected
performance and configuration data to support predicted workload
·
Cloud migration model to support maintenance window
schedule and concurrent cloud/on-premise availability
·
Networking topology, such as VNets, firewalls,
ExpressRoutes, inbound/outbound availability
·
Plan for Active Directory migration to/integration with
Azure Active Directory
·
On-premise to cloud license transition for IaaS workloads
Cloud Deployment
The deployment phase of the Azure cloud migration will
consist of creating:
·
Key Azure elements, such as tenants, subscriptions,
resource groups and resources
·
Configuration and synchronization of the Azure Active
Directory with on-premise Active Directory
·
Networking configuration, such as public/private address
spaces, VNet/peering, Network Security Groups (NSG), ExpressRoutes, site to
site VPNs, firewalls, etc.
·
Virtual Machine (VM)/Database migration to the new
infrastructure using Azure-native tools such as Azure Site Recovery, Azure
Backup and SQL Service Migration Assistant
Five simple steps to achieve Azure
cloud migration
1. Map application workloads
Use a single interface to view all applications, on-prem
and in the cloud. You can then easily understand how applications are connected
and develop a reliable plan to move data to the cloud.
2. Identify common service dependencies
Common service dependencies can be anything from Active
Directory to DNS to an update service within your environment. Take advantage
of Guardicore’s process-level and application dependency visibility, contextual
relevance, and real-time and historical views.
3. Identify business dependencies
What other applications depend on your applications? Once
you use Guardicore to comprehensively map out dependencies, you can confidently
accomplish your legacy applications migration – without breaking or
misconfiguring anything.
4. Gradual lift and shift
Achieve your cloud workload migration with speed, clarity,
and assurance – and zero downtime. Continually monitor and assure a smooth
transition from on-premise to the cloud.
5. Post migration dependency validation and policy enforcement
Implement granular micro segmentation policies, as well as
threat detection and response features. Fill the gaps in cloud-native security
and keep your critical assets secure.

The Modern
Microsoft Cloud Model – a suite of applications and services
The Microsoft Cloud Model is based on a suite of
applications and services: Azure, Azure IOT, Azure Virtual Machine, Azure SQL,
Azure Functions, Docker Helper, Power Apps, Office 365 Suite, Sharepoint, Power
BI, Teams, Automate and Dynamics Applications (Business Central is one of
them).
What version
of SQL Server does Azure use?
With SQL on Azure VMs, you can use any of the
platform-provided SQL Server images (which includes a license) or bring your
SQL Server license. All the supported SQL Server versions (2008R2, 2012, 2014,
2016, 2017, 2019) and editions (Developer, Express, Web, Standard, Enterprise)
are available.

What is the
size of azure sql database?
Basic tier the maximum size for a database is 2 GB. For a
Standard tier the maximum size is 250 GB. For a Premium tier the maximum size
is 1 TB. On elastic pools the maximum size is 500 on Premium tier. For more
details, please read below article:

Azure Hybrid
Use Benefit: -
What is Azure Hybrid Benefit?
A benefit that allows you to migrate to cloud at big savings.
You save up to 40% on Windows Server virtual machines by paying base compute1
rates!
How do I qualify?
You need active Software Assurance on your on-premise
Windows Server licenses.
How do I activate this benefit?
Deploy a new virtual machine in minutes using Azure
Marketplace images. Upload a custom virtual machine. Free migrations with Azure
Site Recovery.
Can I apply it retroactively?
You can retag your existing VMs in Azure with this benefit
by using the retroactive tagging feature and save more money.
Note: -
1. Base compute
equals Linux rates.
2. Each Windows
Server 2-Processor license or each 16-Core license set is entitled to two Azure
instances with up to 8 cores each, or one instance up to 16 cores. Benefit
applies both to Standard and Datacentre editions. No program restrictions, i.
e. - benefit available irrespective of where customer buys their Azure: EA,
CSP, Web direct etc.
3. Pre-built
gallery images are available only for Enterprise Agreement customers.
4. Free for first
31 days
Microsoft
Azure: the cloud for intelligent solutions: -
1. In addition to having the traditional
on-premises enterprise data tools— such as SQL Server—Azure provides SQL
services that connects data to AI services
2. This enables quick adoption of technologies,
such as deploying a global mobile application that integrates with facial
recognition services
3. The ease of integration enables anyone to
build solutions like that
4. From bot frameworks to cognitive services, you
can fundamentally change the way your business goes to market with Microsoft’s
power AI platform
Benefits gained by interviewed customers that migrated or
re-architected some or all workloads from on-premises to IaaS include:
·
Greater revenue opportunities from business-to-business
(B2B) and customer web channels with a solution that is more mobile and reliable
and meets scale and seasonality needs.
·
Increased profits from those revenues.
·
Improved production efficiency.
·
Reduced datacentre, IT resource, and outsourcing costs.
·
Easier and faster software and hardware management (such as
patching and support)
Total Cost of
Ownership (TCO)
The Total Cost of Ownership (TCO) Calculator can be used to
estimate the cost savings you can realize by migrating your workloads to Azure.
You specify the details of your existing infrastructure, various cost assumptions
you want the tool to work with, and then you receive a report that shows
on-premises costs compared to Microsoft Azure costs.
·
DC migration tends to be a higher number since economies of
scale kick in when you start moving thousands of VMs vs. a few applications at
a time. Best example of this is you’re moving entire racks out of your colo
which is why the numbers improve.
·
Rehost is a higher number than refactor because Azure
3-year Reserved VMs are so competitively priced.
·
Rebuild (using App Service) provides similar savings
numbers but has a better scalability story (ability to dial down/up based on
demand).
The Azure TCO calculator can understand the specific of
your environment and then you can further refine your business case. How does
it do that?
·
Enable Azure migrate to go back and update TCO with
accurate inventory scan
·
Azure migrate also does the right sizing to figure out what
type of VM you should be running on.
·
Application dependencies captured by Azure Migrate will get
passed to TCO as well
·
TCO calculator displaying Migration options
How can TMC help?
Why we need Azure Migrate?
We need Azure Migrate because:
1. Unified

migration to Azure Cloud.
2. Range of
Tools: It offers a wide range of tools for monitoring and migration.
3. Assessment and
Migration: Servers, Databases, Web Applications, Virtual Desktops, and
Data can be assessed and migrated using a hub.
