Application Migration Strategy
Cloud migration is the process of moving data, applications, and other business data elements into a cloud-computing environment. There are various types of cloud migration processes. Data can be migrated from an on-premises data center to a public cloud or from one cloud platform such as AWS or Microsoft Azure or Google Cloud. Every business needs to have a plan or strategy for its cloud migration processes before they execute the task. These strategies need to be flexible in order to allow for changes as the migration process advances. Also, these plans must dictate how the business wishes to shift and in what order their applications are to be moved or migrated. Some of the most important aspects of a cloud migration strategy has been discussed below.
Lift and Shift Application Migration
Milletech Architectural Planning and Design Team help migrate a workload to the cloud without redesigning the application or making code changes with due feasibility studies. This is the easiest and at the same time the fastest method of cloud migration processes. The advantages of IaaS, namely, its scalability and flexibility are not available in such cases. There are various tools that can help organizations in undertaking such a task. Whatever the process of migration maybe, once the apps are finally up and running in a cloud, it becomes much easier for organizations to re-architect and optimizes those apps.
Cloud Optimized Application Migration
To utilize Cloud optimized strategy for migrating to the cloud by refactoring an application to take advantage of cloud-native features and capabilities.
Platform (PaaS) Optimization
It includes optimization of the cloud services is required but the major investment is not needed for that matter, as the application’s core structure remains almost the same. Developers can use familiar resources in such cases, like development frameworks, legacy programming languages, and caches of a company’s codes. The main disadvantage of this strategy is the still-evolving PaaS market; it still cannot furnish developers with some capabilities that existing platforms can offer.
Application Architecture Optimization
Another strategy for app migration into the cloud is re-architecting or refactoring. In essence, this means to re-image how the app was structured and developed in the first place. Sometimes refactoring can help businesses to add new features for better performance, which would otherwise have been impossible. However, like all other strategies this one also has a weakness; the loss of legacy codes and developmental frameworks. On the other hand, this strategy gives you top-notch developer tools including cloud-specific tools. Customization data models and app templates are available as productivity tools from the PaaS providers. However, with PaaS, clients tend to rely more on the providers and as such, any fallout overpricing and any other trivial matters can disrupt business.
Application Migration Methodology
Need and Impact Analysis
Our migration evaluation team analyzes that the application is a good fit for the new cloud environment. Customer workload can include applications that are not yet ready to migrate or applications that simply work better in an on-premises environment due to sensitive data, custom tools, or development environments.
Planning: Migration Methods
Evaluate migration methods. The method you choose depends on your workload compatibility with the cloud platform.
Lift and shift
The fastest model. With this method, you transfer the workload “as is” without adjustments. This method works only when you transfer to a fully compatible environment. This model is best suited to companies with a fast-paced production.
It is a middle ground between the three methods. With this model, you make minimal adjustments to adapt the apps to the target platform.
The most time-consuming and expensive method. With this model, you rewrite the entire application to make it compatible with the cloud platform. Developers often modify the app to take advantage of cloud-based features
Planning: Choose Provider
There are several considerations to make when choosing a cloud provider. The first aspect that comes to mind is cost. But there is more in a successful migration than keeping the budget low. A key aspect is the compatibility of your applications with the platform. The compatibility of application and development tools can make you refactor your entire application. This increases the time and the cost of migration. Other things to consider include the scalability, flexibility, and reliability of the platform.
Migrating to the cloud involves financial, security, and governance risks. Security is the top concern for organizations migrating to the cloud.
