Application migration to the cloud is the process of moving your on-premise applications to the cloud environment. During the process, the entire application data, sub-applications and processes would be migrated to cloud servers.
Various methods of application migration:
There are various methods of application migration using the cloud. The lift-and-shift migration process can be used to migrate the entire application with its lock, barrel, and stock. The method doesn’t call for significant changes or code revamps.
In other cases, the code and the application design or it’s IT architecture might require minor to major tweaks to facilitate the migration.
The application data is usually transferred using one of the following three application migration methods:
● Using a public internet connection – Where the volume of data is less and can be quickly sent across the internet.
● Using a dedicated/private network connection – Where the volume of data is relatively large and requires high-end security, encryption, and bandwidth.
● Physical transferring – In instances where the volume of data is enormous, and it becomes impossible to transport over the Internet, the data is uploaded to an appliance which is shipped to the cloud server location. The data is then uploaded to the cloud server.
AWS Migration Hub, Google transfer appliance, AWS Snowball, Azure Migrate are some of the most commonly used migration services.
Benefits of application migration using cloud
83% Of Enterprise Workloads Will Be In The Cloud By 2020, says LogicMonitor’s Cloud Vision 2020: The Future of the Cloud Study (Opt-in required). Cloud is becoming the default choice for enterprises to host their sensitive and demanding applications. Here are the benefits of cloud that are luring enterprises in large numbers.
Pay-per-use is one of the successful business and pricing models that cloud has introduced to the enterprise IT space. In the pay-per-use model, the enterprise pays only for the resources used during a given period. There is no capital lock-in or coerced buy-in of resources that the enterprise does not require. It saves a bulk portion of IT overheads. For example, enterprises have to pay only for the number of users they have subscribed the service for, or for the storage space occupied, or the number of sessions transacted in a month and so on.
Elasticity refers to the ability of an application to expand or contrast in response to its workload requirements quickly. In layman’s terms, it is the scalability that is being offered when the application requires more resources or wants to cut back on the existing capacity. One of the benefits of application migration is this scalability.
Cloud elasticity or scalability ensures that the migrated application has ready availability of resources. Enterprises can always prepare themselves with a minimal amount of resources and scale them as the volumes pick up. The flexible capacity availability also helps keep costs low as well as ensure stable performance.
Cloud servers are more reliable than on-premise systems. They are not bogged down by the hardware issues and performance glitches which is commonplace amidst on-premise systems. Also, since virtual networks power them, controlling, maintaining, and managing them is relatively easier. Remote system admins can be entrusted with the task of handling the cloud servers.
