Cloud Architecture

Your cloud architecture is unique and influences your future

Based on your business strategy, requirements and technology investments, your cloud architecture describes how your organisation uses the components and technologies required for cloud computing.

Creating your cloud architecture is more than selecting different cloud-based services. It involves defining the role of each service, how they communicate with each other and how users interact with these services, generating maximum value for your business.

Failure to create a cloud architecture that is unique to you can lead to applications that do not meet requirements, increase costs or become a liability for your organisation.

Leveraging different cloud delivery models

Your cloud architecture should take advantage of different cloud delivery models as dictated by your cloud strategy:

• rehosting applications with Infrastructure as a service (IaaS) 
• refactoring applications with Platform as a Service (PaaS)
• replacing applications with Software as a Service (SaaS)
  

Generally, you will realise more benefits and unlock efficiencies as you move from the top to the bottom of this list. Correctly matching each application to the proper delivery model depends on the application's goals, requirements and current state.
