Infrastructure Modernisation: Lift, Shift, and Optimise

All modern enterprises today are consciously using cloud-based services to some extent and are realising significant benefits in terms of flexibility, agility, and cost as a result.

We are seeing increasing numbers of our customers turning to the cloud to meet business strategy and growth goals, and in particular, a rise in the number of businesses moving on-premise IT infrastructure to the cloud.

Why move on-premise IT infrastructure to the cloud?

There are various potential triggers than can prompt organisations to move on-premise IT infrastructure and applications to the cloud. These include:

  • Rising on-premise IT infrastructure costs
  • An aging or out-of-support legacy IT infrastructure
  • Security threats
  • Storage capacity limitations
  • Increased agility required to deliver business growth
  • Complex availability and disaster recovery needs
  • New compliance regulations

The benefits of moving to the cloud include increased agility and enhanced security. There’s also the factor of lower costs – for example, through the ability to take advantage of unique cloud offerings, such as paying up front for resources for one or three years.

The Simplex Proposition

At Simplex, our Infrastructure Modernisation service has been created to support our customers looking to address IT infrastructure challenges and meet business growth and transformation goals. Whether a single on-premise server, a small comms room or a full-blown data centre, moving to the public cloud delivers increased agility, enhanced security, and lower costs.

Our Infrastructure-as-a-Service offering is designed to help businesses transform an existing on-premise or hosted IT infrastructure to Microsoft Azure-based. Using industry best practice our experts will work in partnership with your team to assess, migrate to, and optimise your existing IT infrastructure in the Microsoft Azure cloud, and can provide ongoing service management of your new IT infrastructure.

The service comprises the following phases:


During the assessment phase, our team will:

  • Gain a full understanding of your business transformation goals
  • Assess and review the existing IT infrastructure and applications to evaluate migration readiness
  • Identify a desired future state IT roadmap
  • Propose a new cloud solution design to enable you to achieve your business goals


Based on the output of the assess phase and the agreed target solution, our team will use one of the following methodologies to move your infrastructure to the cloud:

  • Rehost: a simple and cost-effective ‘Lift and Shift’ of your existing IT infrastructure to the Microsoft Azure cloud
  • Refactor: where possible, we will move appropriate elements of the IT infrastructure to Platform-as-a-Service (PaaS) solutions, to drive scalability and cost efficiency gains
  • Replace: with this option, there’s transition from an infrastructure-based model to a Software-as-a-Service (SaaS) solution


The optimise phase comprises:

  • Analysis and monitoring to manage cloud spend and use, to allocate and trim costs to build towards your next cloud investment
  • Use of security and management tools to govern, secure and monitor your cloud investment


Optional managed services include:

  • Monitoring your cloud infrastructure
  • Reactive support
  • Security and patch management
  • Backup
