Just like moving house, where boxes need to be packed, labeled and stacked, a migration to the cloud requires some preparation and planning. First and foremost, this includes selecting the environment or applications that will be allowed to change location. In addition, the choice of migration type is critical.
In this blog article, we will introduce you to the different migration strategies. After reading this article, you will understand what a cloud migration is, what types there are and which strategy is most suitable for your migration.
#1: Refactor or Rearchitect
In this migration strategy, you move an application or change the architecture by leveraging the cloud-native value-adds of the new environment to improve agility, performance and scalability. A simple example of this is moving an operating system or database to the public cloud.
In AWS cloud-speak, this could involve migrating your on-premises Oracle database to the Amazon Aurora PostgreSQL-compatible service, for example.
#3: Repurchase or "drop and store"
As the name of the migration strategy suggests, this involves the repurchase of a product, usually switching from a traditional license to a SaaS model (Software-as-a-Service model).
For example, if you migrate your local CRM system to a provider such as Salesforce, Hubspot or others, you buy a new product, but one that is operated for you on-demand in the cloud.
#5: Relocate ("Lift & Shift" at the hypervisor level")
Relocate pattern migration describes moving infrastructure to the public cloud without buying new hardware, rewriting applications, or changing your existing operations.
So far, so good. Specific to this migration strategy, however, is that it can only be deployed VMware Cloud from Amazon Web Services (AWS), which only supports virtual machine (VM) compatibility and workload portability between your on-premises environment and AWS. Sounds complicated, but you can remember: it's all like "Lift & Shift" just exclusively for VMware applications.
An example is migrating your hypervisor hosting your Oracle database to VMware Cloud on AWS.
Last but not least, Retire is available as a strategy for your cloud migration. Similar to the previous Retain strategy, this is also a more passive type of migration. Here, you decommission or remove applications because they are no longer needed within your source environment.
Cloud migrations are among the key components of cloud strategies. The relevant hyperscalers such as Amazon Web Services have therefore developed programs that enable specialists and customers to analyze the possibilities and potential of cloud migrations. Particular attention is paid to which environments and applications are suitable for cloud migration, both in terms of operation and cost.
One such program is the Amazon Migration Evaluator (formerly TSO Logic), which can accelerate the decision-making process for a cloud migration and make it transparent. The first step is to collect relevant data from your IT history as well as from your current operations.
In conclusion, as mentioned at the beginning, migration involves thorough and comprehensive preparations and analysis. In addition to the right strategy and planning, having the right expert at your side is also a key component.
As part of the Public Cloud Group, Innovations ON has already carried out more than 300 cloud migrations. We cover all company sizes, industries and most importantly, all migration strategies. We are happy to advise you and your team on the preparations, planning and subsequent implementation. Together we will find the right path to the public cloud.
