The best way to manage a dynamic cloud environment is to set up guardrails that allow you to manage your infrastructure, by way of exception. This allows you to manage your environment in a relatively hands-off manner, with alerts and policies around financial management, operational governance and asset & configuration management which will eventually help you to stay ahead of changes and save money. Let’s learn which types of alerts and policies can save you money, and get some examples.
STAYING WITHIN BUDGET
It’s not always simple stay within an allocated budget. In order to help departments and groups to do so, you can set a policy to alert budget owners when projected spend is greater than their set budget. For example, if projected month to date cloud spend is greater than100% of budget, then send an email notification to budget owner.
OPERATIONAL GOVERNANCE POLICIES
Automating basic operational tasks is one of the best ways to free up your IT staff’s time to let them focus on more strategic and innovative initiatives. This could include automating the
detection and elimination of zombie’s infrastructure, or scheduling environments to turn off and on again. For example, instances running 24/7 – Amazon will bill for 672 – 744 hours per instance, depending on the month. If Dev or QA environments will be switched off between 8PM and 8AM on weekdays and stopped weekends and holidays, then total billable hours per month would decrease in 65-70% – saving you 435 – 483 instance hours per month.
PERFORMANCE MANAGEMENT POLICIES
Understanding and monitoring performance of your AWS environment is crucial. Such information can be gathered using CloudWatch, which provides data on CPU & Networking usage. It’s also important to consider memory & disk utilization, which can be monitored by CloudHealth’s monitoring agent on your EC2 instances. For example, if average CPU usage is < 20% AND memory usage is < 35% AND disk throughput is < 35% for over two weeks, then send email notification. A potential reduction which can save you 50% of that instance costs. Ran Blumenfeld
