The Problem: Fast Cloud Migration of existing Applications needed

To save cost and also accomodate for the ever increasing number of IT resources a company plans to close 75% of its data centers and move to the cloud.  It’s planned to close the first data center within the next 6 months and migrate all running workloads to the cloud.

The applications the company is developing and operating in its IT environments vary heavily. Some applications are relying on a very traditional tech stack while others would greatly benefit from the capabilities of the cloud services such as a managed kubernetes, object storage and analytics services.

The Solution: Using Cloud Zones

Cloud Zones are a construct we find to be formed in multiple organizations using one or more cloud platforms to accommodate different requirements to operate and develop a diverse set of applications. A Cloud Zone forms an organizational and technical frame independent of cloud platforms for teams to build, test and operate applications on.

The company defines two cloud zones for the different types of applications.

They decide to have a “lift and shift”- zone which will host the more traditional workloads. Even though the objective is to modernize some of those applications over time they decided to move the applications directly in the lift and shift zone and investigate the potential for refactoring those applications later. Applications in this zone will continue to run on managed VMs.  .

Workloads that will benefit from the scalability and flexibility of the cloud are moved directly to the “cloud-native” zone. In the future it is planned to move some of the to be refactored applications here from the lift and shift zone.

Cloud Zones – an important opportunity for your cloud governance

  • Cloud Zones are a construct we find in several organizations that use one or more noisy platforms.
  • Cloud Zones provide an organizational and technical framework independent of cloud platforms for teams to build, test and run applications on.
  • Cloud Zones are a way for cross-platform Cloud Foundation teams to align around a compliance framework.
  • Cloud Zones are defined by Cloud Foundation teams to agree on a common and equal level across clouds.
  • Cloud Zones have different cloud-dependent implementations, but follow a compliance scope.
  • Cloud Zones use common best practices when it comes to cloud security, financial risk, flexibility and time to cloud.
  • Cloud Zones are a good way to communicate and justify the balance between agility and control in an organization and foster an understanding that reduces doubt.

Compliance and security across all cloud zones thanks to Landing Zones

In order to provide the development team with maximum flexibility within the cloud zones, but at the same time ensuring security and compliance requirements, landing zones can be established for each cloud zone. You can define generally applicable rules for the particular zones, and developers are free to move within the boundaries of these rules.

In general, cloud-native provides more freedom to you because you can use a large variety of services and experiment and Lift and Shift is more restricted in regard to what you are allowed to do. To keep security and compliance standards and still provide your team with this flexibility in the cloud-native zone, you can set stricter policies in your landing zone - only those team members who can demonstrate appropriate cloud training are authorized, and only services from the EU may be purchased. Team Lift and Shift, on the other hand, has no access restrictions, but is has less opportunities to work with since they have no access to the whole range clouds offer.
