Capacity, Consumption and Utilization

Oversized Servers Found (IO)

Newvem analytics provides comprehensive visibility to your EC2 footprint with drill downs from a consolidated view to a detailed resource status report. Newvem continuously analyzes EC2 instance utilization patterns and provides a down-to-the-hour picture of your AWS EC2 consumption and usage. Use it for Free!

Newvem monitors cloud servers that are active, but found that their IO has been mostly idle for a considerable amount of time. This means that you are using oversized servers, which is not cost efficient. We suggest to consider resizing these servers (i.e. move your workload to smaller, lower cost servers to reduce your compute costs). Instead of starting a new instance and configuring it from scratch, one may be able to simply resize the existing instance by moving it to a more suitable hardware configuration.

Excessive Number of EBS Volume Snapshots

Newvem checks for the sprawling of EBS volume snapshots, which results in an excessive number of snapshots. As this decreases the overall efficiency of the backup process, and is also not cost-efficient, we suggest to remove the unnecessary snapshots and define a retention policy. To do so, check your Newvem EBS snapshots report to find the EBS volume that holds multiple snapshots and remove the unnecessary snapshots, refine retention policy, and generate an automatic procedure.

Abnormal Server Count Growth Pattern

Newvem monitors changes in the growth pattern of your servers. We have identified an abnormal change in your server count over the last few days. We suggest that you keep track of your server count over the next few days, and check that the server count growth is aligned with your planned growth and budget. If necessary, adjust your footprint accordingly.

Abnormal Compute Cost Growth Pattern

Newvem monitors changes in the growth cost pattern of your compute resources. We have identified an abnormal change in your overall growth rate in the time range . We suggest to keep tracking costs over for few days, and check that the cost growth is aligned with your expectations and budget. If necessary, adjust your footprint accordingly.

The Challenges of an Effective Cloud

Clouds move fast, and change fast.  The advantage is having elastic, fast, and un-planned deployments. However, uncontrolled usage leads very quickly into footprint sprawl – cloud sprawl, overspend and unpredictable behavior.  Contrary to VM sprawl, where the virtualization environment provides natural containment, cloud sprawl can be rather chaotic and expensive – exactly for the same reasons we enumerated above: lack of visibility and control, unpredictability, new processes, and different practices.
