Microsoft Azure is a powerful cloud platform offering a wide range of features and capabilities for application management, highly suitable for IT environments of enterprises with stringent compliance and data protection requirements. While planning to migrate workloads to Azure Cloud, these 4 key migration strategies mentioned below play a significant role. Our entire strategy to migrate Azure is defined based on the model that we choose.
Four Migration Strategies include:
- Rehost — Moving the applications from an On-Prem environment to the cloud with zero changes.
- Refactor — Moving an application to the Azure cloud with minimal code changes.
- Rearchitect — Revamping the application codebase and moving it to a cloud-native architecture.
- Rebuild — Keeping the old application aside and building similar functionality from scratch using Azure Platform as a Service (PaaS) capabilities.
Sometimes, moving applications and data to the cloud probably seems daunting because the developers no longer have control over the services, and as a result, data will run rampant. However, Microsoft Azure offers tools to prevent such mistakes before implementing the Azure migration.
Let us look at the key points to consider while migrating to the Azure cloud.
Azure cloud migration is often used because numerous cloud platforms are good either at one or two things. But, on the other hand, Azure is a competent and versatile platform in all situation ranges. For example, it can be ranging from size to cloud-enabled file backup.
Ensure you have enough Bandwidth
In any migration type, whether a public or private cloud, the bandwidth factor can be overlooked easily because it is a continual evaluation since it might consume all the savings. In the case of hybrid Cloud Migration, the range is taken care of by an architecture specialist.
Latency is another crucial factor to consider, where businesses often move their workloads to the cloud, which run their service on LAN where WAN will no longer support the excess load. If this happens, one of the best-case scenarios is that the newly migrated application gives a slow performance, and the worst case is the full network halts. So, it is always better to ensure that local bandwidth is enough to support the migration.
One of the most significant factors that both software developers and service providers are concerned about is the application’s functionality after moving to the cloud. Still, many software service providers are only in the exploratory trial stages on how their application is going to run in a public cloud environment.
Always ensure that performance and support are on the top priority before committing to any migration because it is better to dig deeper about the quality and performance given by the service provider. For example, by switching the application to the Azure test environment, we can discover the potential risks prior to moving to production.
Consider DR and Continuity
Microsoft holds a colossal infrastructure where our data is replicated across the place; that does not mean that we will not have an outage. And, considering Azure, it can restore the data loss if we set up backup solutions on local storage.
Since there is a good count of variables involved in the cloud, there exist few chances of a data outage. For instance, when we move to the Azure cloud, we should plan for the Disaster Recovery and business continuity plans. Then, followed by it, ensure for their actual work when required.
Secure your Cloud Environment
Securing the cloud environment is a crucial factor, and Microsoft Azure allows for an easy understanding of the security controls on what we are responsible for and what security functions Azure is responsible for, such as cloud security.
It is often overlooked, and it includes the network for internal and external traffic. We should also consider the security system and Deep Packet Inspection factors, which are available in a considerable count in the Azure marketplace.
Businesses should have significant planning before implementing the migration. Being prepared with a well-structured plan like using the Azure cloud adoption framework makes the migration smoother and affordable. If you plan for the migration, Sunera Technologies provides you the best suitable migration path that guarantees successful migration and greater savings.
Suneratech, being a pioneer in various cloud migrations for around two decades, with a unique differentiator Zero Cost Cloud Migration (ZCCM) approach, enables businesses to implement the migration at zero upfront costs with our continual application support.
