Azure VN
Network addresses and subnets are not trivial to change once you have them set up
Microsoft’s licensing on the Cloud
Migrating into the Azure Cloud allows you to use Microsoft’s licensing, so you won’t need to keep track of the licensing.
Potential stumbling blocks to migrating to the cloud:
Migrating resources into a solution that is not cost-effective.
Potential stumbling blocks to migrating to the cloud:
Underestimating the length of time it will take to modify on-premises applications to work properly in the cloud
Potential stumbling blocks to migrating to the cloud:
Not having a strategy to revert changes to the on-premises environment just if things don’t work as expected
Situations in which there is a significant drop in performance after migrating to the Azure cloud caused by various factors, including the following:
implementation of the wrong solution
Situations in which there is a significant drop in performance after migrating to the Azure cloud caused by various factors, including the following:
underestimating how latency can impact performance
Situations in which there is a significant drop in performance after migrating to the Azure cloud caused by various factors, including the following:
not collecting enough data to help determine the best solution for the companies existing infrastructure
Potential stumbling blocks to migrating to the cloud:
Underestimating the costs associated with migrating services into the cloud. Azure provides a wealth of resources to help estimate the cost. However, those tools will only be as effective as the information that we provide.
Potential stumbling blocks to migrating to the cloud:
Not properly setting up the resources to ensure high availability.
Potential stumbling blocks to migrating to the cloud:
Not understanding which service interruptions are covered with the SLA and how to make sure that the configuration is properly set up to qualify for the different SLAs
Potential stumbling blocks to migrating to the cloud:
Not properly explaining to the stakeholder’s the value of and advantages of migrating resources into the cloud. Everything has a cost associated with it, whether it is the day-to-day maintenance, man-hours to troubleshoot an issue, man-hours to come up with a solution, etc. It will be your responsibility to monetize all of the different tasks to have a fair comparison for costs associated with the cloud compared to on-premises.
The key stakeholders involved with the migration process
IT Team/CTO
Finance Department/CFO
Business owners/CEO
The organization’s readiness to the cloud
How much the migration will cost?
The security of the data on-premise compared to how secure the data will be within the cloud
Define the must-have components that are on-premise to be replicated in the cloud. Some legacy applications have dependencies that cannot be replicated in the cloud.
What data should be migrated ?
What is your primary reason for migrating to the cloud?
Reasons some companies are not ready to migrate into the cloud
Business Applications are not straightforward and may require extensive modification to work in the cloud.
Reliable Internet-With your resources in the cloud, you will need reliable Internet to access your resources that have been deployed in the cloud. That means if your WIFI is down, you will not have access to your resources and if your speed is slow, you will lose productivity.
Some business applications run faster locally. However, there are different tools to help with latency, some legacy business applications that cannot be optimized to run in the cloud without completely redeveloping the business application.
