Excellent strategies for your migration to a public cloud

Repurchase strategy

One purchase with countless advantages. Profit from the added value of a public cloud and take direct advantage of software as a service.

As this migration strategy’s name suggests, it involves buying a new product where you switch from a traditional license to a software-as-a-service (SaaS) model. For example, you can migrate your local CRM system to a supplier such as Salesforce, Hubspot, or others. Buy yourself a new product that is then operated for you on demand in the cloud.

Relocate migration

The easy way to migrate your VMware applications to a public cloud.

Migrations based on the relocate model shift infrastructure to a public cloud without the need to buy new hardware, rewrite applications, or modify your existing processes. It might sound complicated, but you’ll notice it all works just like “lift & shift.” The only difference is that it’s solely for VMware applications.

Retire strategy

Shut down the unneeded elements of your IT tactically and concentrate on your key infrastructure.

Retiring is another strategy in your arsenal for a public cloud migration. Similar to the retain strategy, it’s a more passive form of migration. It involves you shutting down applications or removing them because they will no longer be needed in your infrastructure.

Rearchitect or refactor

Capitalize on the added value of a public cloud and count on limitless scalability, maximum security, and fully transparent costs.

With this migration strategy, you move an application or modify the architecture by drawing on the cloud-native added value of the new environment. In doing this, you improve agility, performance, and scalability. Migrating an operating system or database to a public cloud is a simple example of it.

Replatform migration

A new public cloud platform means new opportunities for your application’s success!

Often called a “lift & reshape” strategy, it refers to the migration of an application to the cloud that involves performing an optimization simultaneously. The goal is to leverage the benefits of the newly obtained cloud functions for the application itself.

Rehost – “lift & shift” migration

Take off to a public cloud without making any changes to your application or workload. It’s the simplest way to accomplish a migration.

“Lift & shift” is one of the most well-known models for migration, which can mainly be attributed to the rapid time it takes to complete. Rehosting moves your application to the public cloud without making any sort of changes. You gain the advantages of a cloud environment, such as transparent costs and scalability, without making any optimizations of your application itself.

What you should definitely consider before migrating to the public cloud

#1 Inventory

Before really getting down to business with migration, it is important to know your existing environment in detail. An inventory of your current applications and data will be conducted.
However, the objective here is not only to determine the status quo, but rather to understand which of your workloads should migrate to the cloud.

Not all workloads can or need to migrate to the public cloud per se, so to save costs, time and effort it's important to select in advance.

#2 Migration & operating costs

A proven model for cost assessment is the analysis of total cost of ownership. In simple terms, this compares the existing operating costs of the selected workloads with the potential costs of the workloads in the cloud.

In addition, migration costs are calculated and included in the process. If the cloud is the cheaper model, you also get a “break-even point”.

It is also worth looking into the future here. How will the outlined public cloud environment have to be operated in the future, and what costs will be incurred with different operating methods?

#3 Assign responsibility

Migration consists of preparation, planning and implementation, followed by the operation of the public cloud environment. Many steps require skills and resources.

Which steps you implement with your own team and which you hand over to PCG as your migration partner is completely up to you. We support you with our skills where you see the need.

In order to carry out this division seamlessly during the migration, one of the central points of preparation is to assign internal and external responsibilities.

#4 Select hyperscaler

Depending on the company's target definition and the workloads to be migrated, it is also necessary to find a suitable public cloud environment. In the public cloud sector, there are three major hyperscalers Amazon Web Services (AWS), Google Cloud and Microsoft Azure.

They provide the basic components of a public cloud, consisting of virtual resources such as computing power, storage and network via a freely accessible platform.

The easiest way to find out which cloud environment best suits your needs and requirements is to conduct a cloud assessment.
