JOURNEY TO THE CLOUD

A Guidepost for a Collaborative Modernisation Approach

 

Understand your short and long term cloud goals,

and formulate a strategy to achieve them

 
__________________________________________________

The drivers for moving workloads to the cloud are well documented: Organisations need to simplify operations, reduce costs, and increase application agility to meet market demands. Additional motivations for moving workloads to the cloud include balancing the need to meet regulatory compliance requirements with the desire to greatly increase innovation, performance, and scalability.

But the critical question for organizations to first answer is: What are the specific cloud destination options, and what is the recommended approach to get there? To be effective, organisations need a strategy that fully maximises cloud benefits, including, but not limited to, leveraging a cloud-native landscape.

Short and Long-Term Destination Options

LEGACY TO CLOUD

The selected cloud destination will ultimately depend on the customer’s desired short and long-term goals.

Advanced has the unique ability and experience to migrate legacy workloads to any cloud destination: cloud ready, cloud optimised, or cloud native. The below graphic provides an overview of the three different cloud destination options:

The starting point of any modernisation journey should be a comprehensive assessment – encompassing applications, operations, and the supporting infrastructure. Assessment results should look to validate any pre-selected disposition strategies (sometimes referred to as modernisation patterns), and ultimately assist in defining the overall modernisation approach. Depending on the long term goals – the approach often includes a combination of disposition strategies. For example, a long term goal of re-engineering a large, complex mainframe monolith into cloud-native microservices can be broken into several incremental steps:

  • Refactor applications to a cloud-native language such as Java or C# and run containerised in a cloud ready environment.
  • Optimise applications to obtain desired level of elasticity at the container level, running in a cloud optimised environment. In parallel, re-engineer specific functionality identified during the assessment phase with Java-based microservices.
  • Continue to optimise the application, incrementally re-engineering to microservices and progressing towards a cloud native environment, realising that it may not be necessary to replace the entire monolith in the short or long term. It’s important for each application to be analysed critically via an in-depth assessment in order to understand the reality that parts of the monolith might be better served remaining intact.
