Cloud migration services allow businesses to move applications and data to the most efficient IT environment possible. The move helps reduce costs, improve agility, and provide higher security.
Cost
There are many costs associated with cloud migration services. These include hardware and software migrated to the cloud and indirect costs like Organization Transformation and residual (sunk) costs for on-premise infrastructure and data center capacity.
Additionally, there are often additional costs for network egress charges, compute prices that don’t autoscale, bulk storage discounts, and proprietary migration tools.
According to Microsoft cloud migration services experts, the most basic migration strategy is ” lifting and shifting” workloads to the cloud. This involves migrating existing on-premise VMs and scale-out storage to the public cloud. This approach is less complex and typically has a lower cost.
Still, it does not offer the same level of flexibility as refactoring, which requires changing the application architecture to take advantage of cloud capabilities. It is important to weigh the pros and cons of each option.
Scalability
In addition to a comprehensive migration strategy, scalability includes continuous monitoring of system performance and minimizing hardware support costs. This can be done with cloud services such as Application Management Services or Business Analytics Services.
IT leaders should evaluate all applications during migration to ensure they are a good fit for the cloud. If not, the application should be refactored or rebuilt to take advantage of modern features available on PaaS platforms.
Another consideration is the migration’s potential to disrupt business operations. A backup plan should be in place to avoid lengthy downtime. Migrating large databases requires calculating bandwidth requirements and providing enough network connectivity to support the data transfer.
Some providers offer physical transfers, such as loading local data onto an appliance and physically shipping it to the cloud provider, for massive databases that cannot be transferred via the Internet.
Flexibility
Cloud migration services provide a flexible way to transfer data, applications, and workloads to the cloud.
Companies can choose from various techniques, including lift-and-shift (moving an application to the cloud without modification), refactoring and re-architecting (transforming an existing app architecture to take advantage of cloud-native features), and rebuilding applications.
Once the migration is complete, testing and monitoring the new environment is important. This will help ensure that the new system meets business objectives and allows for a smooth transition between legacy systems and the cloud.
This will help reduce the need for hardware support and free up resources for innovation and revenue-generating activities. This will also enable businesses to improve their end-user experience and enhance productivity.
Security
Cloud migration services have security measures to protect the data and applications during the transition.
These include implementing a SIEM system to centralize alerts and logging and integrating them with analytics, automation, and machine learning to help identify attacks in progress. They also ensure that compliance standards are maintained during the migration.
They can assess the sensitivity of your data and implement appropriate controls, such as encryption, to keep it secure. They can also advise using multi-factor authentication for cloud access to mitigate the risk of the wrong personnel tampering with sensitive information.
Rehosting is an easy, direct way to move your data and applications to the cloud. It doesn’t involve architectural changes and can be completed quickly with lift-and-shift tools.
Availability
Availability is one of the key factors to consider when choosing a cloud migration service. A good provider will take the time to learn what business processes are involved in your operations, then work with you to determine how those can be migrated to the cloud efficiently.
They’ll also evaluate your applications to ensure that only the essential data is migrated. Stale or redundant data is unnecessary and can add to your cloud costs.
In addition, they’ll look at how your local application stack is organized to identify dependencies that will need to be replicated in the cloud or refactored to accommodate cloud service options.
They’ll then use this information to create a migration plan that includes your business goals and expectations. This will help you avoid unplanned expenses and delays in your migration process.
