Creating An Azure Migration Strategy
More companies are shifting their resources, and computing needs to the cloud, with Azure increasingly becoming the top choice for many because cloud computing has more benefits.
But moving the workload, application, or entire company network to Azure is not a straightforward process. Before they can start moving, an organization needs a plan and develop a strategy for Azure migration.
Creating a strategy is likewise not as simple as it seems. One option to overcome the hurdle is to find a provider of expert azure migration services to ensure that you are on the right track and customize the approach based on your needs.
Planning the strategy for Azure migration
You can ensure a successful move to the cloud when the initiative comes from the company's top leaders. If they support the initiative, it will be easier for the rest of the organization to adopt the process.
Planning the Azure migration strategy involves broad phases and the more definitive steps under each one.
# 1: Assessment
You can better plan the cloud migration strategy by assessing your current systems and workloads. You should know all your organization's assets that you must move. An assessment is critical, so you will know which assets to move, how long the move will take, and the risks involved.
Aside from making an assessment, you need to map out the workloads and applications you want to migrate to the cloud. After this, you can plan out your migration strategy. You can choose from several migration strategies, depending on your need and your allocated time to the migration process.
The migration strategy options you can choose from:
- Rehost or lift and shift strategy. This strategy includes picking up your workload or application and moving it to Azure without any changes. There will be no code modification. You can move several of the business applications you use to Azure Virtual Machine. With this strategy, your organization will remain responsible for the operating system, while the underlying infrastructure will be under Azure.
- Refractor strategy. An application's code or configuration will be altered minimally using this approach. This alteration is necessary to optimize the PaaS tier of the Azure application. You can use Azure's container services or app service for this strategy.
- Rearchitect strategy. In this approach, you need to extend or modify the architecture or codebase of the existing application to fit the cloud platform and improve the application's scalability.
- Rebuild strategy. This strategy is the most prolonged and time-intensive approach, as it involves rebuilding the application from zero, using serverless tiers or Azure PaaS. However, if you prefer to build a new application, you can use Azure's cloud-native technologies such as Azure Cosmos DB, Logic Apps, Azure Functions.
In this final phase, you must optimize the management, cost, and security workloads. First, you need to protect your data with Azure Backup. Then, to monitor your cloud health, you can deploy Azure Monitor. Finally, for overall security, you can use the Azure Security Center to help you, monitor, receive alerts and protect your assets in the cloud from possible cyberattacks.
Migrating to Azure is another significant investment, and you can use the Azure Cost Management to control your costs after migration. But the essential thing to do is to consider why you want to migrate and carefully select the assets you want to move to the cloud.
