Cloud Cost Optimisation

Do you know you can reduce your cloud spend by an average of 35% by properly optimising your cloud resources?

Optimise Your Cloud Spend with Right-Sizing and Right-Buying

  • Identify the sizes of instances needed for each application workload. This requires highly granular data capture of the resources used (CPU, memory, disk I/O & network I/O), because using averages won’t cater for peak demand.
  • If the workload is being moved from an on-premise data center to the cloud, the estate should be optimised when it is moved, using recommendations on the optimal instances to buy. ‘Like for Like’ or ‘Lift & Shift’ is always more expensive than it needs to be​.
  • Understand the capacity of the on-premise estate if Hybrid-IT. Bring work back from the cloud if on premise capacity allows it​.
  • Applications or Services in the Cloud can also be ‘Right-Sized’ based on their actual use of resources.​
  • Identify where the instance needs to run (location) and optimise for cost/performance​.
  • Identify the best way to buy the instance, which depends on how long it is going to run for. This is an aggregated need for that instance size, not the need of one specific instance for one application.
  • Identify how long an instance should run for, and if it is idle, how long before it should be shut down​.
  • Continually analyse the billing engines of the cloud providers to identify optimal usage and policies​.


Identify the sizes of the cloud instances needed for each application workload. Using highly granular data capture, you can determine optimum configuration of burstable or non-burstable instances, and identify idle times and workload periodicity. Once you understand the capacity of your hybrid estate, you can bring work back from the cloud if your on-prem capacity allows it.



Identify where each cloud instance needs to run and pinpoint the best way to buy it, depending on how long it's going to run for and how long before it shuts down if it's idle. By gathering this information and continually analysing the cloud provider billing engines, you can start optimising your cloud usage for cost and performance.



Improve business processes and manage your cost and performance across hybrid IT, on-prem and multi-cloud, all in a single tool with consistent reporting. By using right-size at an application level to correlate your business demand with your cloud service, you can plan for growth, predict upcoming costs and find saving opportunities with advanced predictive analytics and what-if scenario modelling. 

Right-Size, Right-Buy, Optimise & Repeat

Guy Warren discusses the cyclical stages for true Cloud cost optimisation

In this brief webinar ITRS Group's CEO Guy Warren discusses the state of the industry when it comes to optimising Cloud spend. He identifies the exercises which most companies are undergoing already, and provides insight into optimising the process.

Cloud Cost Whitepaper, Optimising Cloud Spend By Right-Sizing and Right-Buying

CIO and Head of Infrastructure, Capacity Management



Job has changed to encompass cloud. Managing a hybrid IT environment with many different tools and no single source of truth. Growing costs with little visibility into the reasons for increased costs. Organization applying pressure to move to cloud but needs to demonstrate how to move to cloud, when to move to cloud and if it really is the most cost effective approach.

ITRS Solutions

  • Single pane of glass across Hybrid IT.
  • Right-sizing and Right-buying for migrations to multi-cloud.
  • Consistent measuring and reporting of costs and opportunities regardless of platform.
  • Detailed understanding of demand and opportunities to reduce idle time to save costs.

Head of Service Management, Software Architecture



Cloud application costs spiralling. Managing a combination of on-premise and in-cloud applications. On-premise applications expected to move to cloud but a "like for like migration" is likely going to lead to increased costs. Unable to forecast costs based on increased demand and likely cloud utilization. What is the most cost effective use of cloud services?

ITRS Solutions

  • Right-sizing and right-buying per application.
  • Detailed analytics on application resource profile to determine optimum cloud configuration and savings opportunities.
  • Correlation of volumes with cloud resources to determine how cloud service usage and cost will increase as demand increases.
  • Visibility into the "transactional" cost of using the cloud by determining the cross-service cost servicing demand.

10 Facts about Cloud Adoption

Public Cloud is a 230 Billion industry growing at 22% p.a. Cloud providers offer some data/tools to help manage costs, but with this level of complexity, it is not surprising 35% of cloud spend is wasted.
