Cloud spend is anticipated to continue its massive growth trajectory for the foreseeable future. However, the spend does not have to match that same growth curve! To help our Clients maintain sound Cloud Optimization programs, we've assembled a series of articles and tips called: 12 for '21 Cloud Optimization Series (note: request a download of all 12 here).
Our fifth chapter in the series: Size it Right!
Once you have deployed resources for a while, you have to check that your instances are optimal. For most clients, instances are set with the right configuration at time of the launch. As your consumption and business environment evolve, the original configuration become less optimal. This discrepancy is the source of cloud waste and more so, if you run a large fleet of instances across multiple applications. Avoid paying for resources that are not used at full capacity, a change in instance size and/or type can translate up to 50% in cost reduction !
Identify your instances for rightsizing.
Native tools (e.g. AWS Compute Optimizer, Azure advisor, GCP Cloud Functions..) can analyze compute consumption pattern and provide recommendations for rightsizing. These recommended instances are ones that balance performance and cost for running workloads. It’s important to be aware of the tools limitations, instances rightsizing takes into account multiple factors such as CPU, storage, memory, networking performance, and more. Your DevOps and application stakeholders have to assess implementation feasibility and later, refine the setup of your Optimizer or Advisor
Develop processes toward instances rightsizing.
While you can perform rightsizing manually , this is not the best option. If installed manually, at scale with large volume of instances, it becomes a labor intensive process to keep up with and make changes to increased workload or change in consumption demand. While AWS Autoscaling or Azure Autoscale automate the scaling of your application infrastructure, these are not easy to set up for systematic rightsizing optimization. In order to fully optimize your costs, it would be in your best interest to invest in a third party tool, or a managed service such as CCO, that can streamline these actions for you.
