We recently discussed how orphaned volumes and snapshots contribute to cloud waste and what you can do about it, but those are just two examples of orphaned cloud resources that result in unnecessary charges. The public cloud is a pay-as-you-go utility, requiring full visibility of specific infrastructure – you don’t want to be charged for resources you aren’t using. Here are other types of orphaned cloud resources that contribute to cloud waste (and cost you money):
Unassociated Elastic IPs
Elastic IPs are reserved public IP addresses designed for dynamic cloud computing in AWS. As a static IPv4 address associated with your AWS account, Elastic IPs can continue running an EC2 instance, even if it is stopped and restarted, by quickly remapping the address to another one of your instances. You can allocate an Elastic IP address to any EC2 instance in a given region, until you decide to release it.
The advantage of having an Elastic IP (EIP) is the ability to mask the failure of an EC2 instance, but if you do not associate the address to your account – you’re still getting charged. To avoid incurring a needless hourly charge from AWS, remember to release any unassociated IPs you no longer need.
Elastic Load Balancers (with no instances)
Cloud load balancing allows users to distribute workloads and traffic with the benefit of the cloud’s scalability. All major cloud providers offer some type of load balancing – AWS users can balance workloads and distribute traffic among EC2 instances with its Elastic Load Balancer, Google Cloud can distribute traffic between VM instances with Google Cloud Load Balancing, and Azure’s Load Balancer distributes traffic across multiple data centers.
An AWS Elastic Load Balancer (ELB) will incur charges to your bill as long as it’s configured with your account. Like with Elastic IPs, whether you’re using it or not – you’re paying. If you have no instances associated with your ELB, delete to avoid paying needless charges on your monthly bill.
Unused Machine Images (AMIs)
A Machine Image provides the information required to launch an instance, which is a virtual server in the cloud. In AWS they’re called AMIs, in Azure they’re Managed Images, and in Google Cloud Platform they’re Custom Images.
As part of your measures to reduce unnecessary costs from orphaned volumes, delete unused machine images when you no longer need them. Unless deleted, the snapshot that was created when the image was first created will continue to incur storage costs.
One of the growing pains that organizations face is the management of isolated pools of data in their cloud environment. Fragmented storage can result from data coming from a number of sources used by applications and business processes. Object Storage was designed to break down silos into scalable, cost-effective storage to store data in its native format. AWS offers object storage solutions like Amazon S3 and Amazon Glacier, Google has Google Cloud Storage, and Azure calls its solution Azure Blob Storage. All options help you manage your storage in one place, keeping your data organized and your business more cost effective.
Although object storage in and of itself is a cost effective solution, there are still ways to optimize and reduce costs within this solution. Delete files you no longer need so that you’re not paying for them. Delete unused files which can be recreated. In S3, use the “lifecycle” feature to delete or overwrite older versions of data. Clean up incomplete uploads that were interrupted, resulting in partial objects that are taking up needless space. And compress your data before storing to give you better performance and reduce your storage requirements.
How to Avoid Wasted Spend on Orphaned Cloud Resources
Don’t let forgotten resources waste money on your cloud bill. Put a stop to cloud waste by eliminating orphaned cloud resources and inactive storage, saving space, time, and money in the process. Remember to:
- Release unassociated IPs you no longer need.
- Remove Elastic Load Balancers with no instances attached.
- Delete unused machine images when you no longer need them.
- Keep object storage minimal – optimize by “cleaning up” regularly, removing files you don’t need.
The premise of the cloud and the resources available to you were meant to be cost effective, but it’s up to you keep costs in check. Optimize your cloud spend with visibility, management, and cost automation tools like ParkMyCloud to get the most out of your cloud environment.
