Navigating AWS storage costs requires grasping several key components that influence storage pricing. Charges Based on Storage Usage Charges Based on Storage Usage AWS bills are based on the amount of data stored within the AWS infrastructure. The fundamental metric here is the gigabyte per month rate, representing the volume of data stored during a billing cycle. For instance, the gigabyte per month rate for S3 Standard is $0.023 per GB per month in the US East (N. Virginia) region. The gigabyte per month rate for Amazon EBS General Purpose SSD is $0.05 per GB per month in the same region. Type of Storage Type of Storage AWS offers different storage services with different features and prices. Amazon S3, for instance, is designed to store large amounts of unstructured data. Amazon Elastic Block Store (EBS) is block storage built for storing data with high performance. Amazon S3 Amazon Elastic Block Store Amazon S3 offers different levels of storage, each with its own unique pricing and availability. For instance, with S3 Standard, you can frequently access data with instant availability. With the S3 Infrequent Access tier, you can store data at lower prices, but it will take longer to access. EBS also provides various volume types, each having distinct price and efficiency features. Amazon EBS General Purpose SSD is designed for general-purpose workloads and offers a good balance of performance and cost. Amazon EBS Provisioned IOPS SSD is designed for workloads that require high IOPS and offers the highest performance, but it is also the most expensive volume type. Access Rates Access Rates Different AWS storage tiers have different access patterns that affect their costs. For example, S3 Standard allows you to access data frequently with instant availability, while S3 Infrequent Access gives you less frequent access but offers lower prices. If you have frequently accessed data, you will want to use a storage tier that offers instant availability. Instant availability will ensure that your data always remains accessible. If you have data that you don’t need to access as frequently, you can use a storage tier that offers lower prices while compromising the speed at which you can access your data. With N2W, we automate the process of data transfer to ensure that you are taking advantage of the most cost-efficient storage tier for your availability and latency needs. N2W Data Egress Data Egress Data egress is the cost of transferring data to an external network from your AWS environment. For example, downloading data from an S3 bucket to your computer will incur a cost for data egress. The rate for data egress varies depending on the region where your data is stored and where you are transferring the data to. The AWS Pricing Calculator is available to estimate your costs, although determining your data egress patterns with just this tool can be challenging. (TIP: to help you navigate the calculator, check out this blog post). AWS Pricing Calculator this blog post Data Transfer Data Transfer Data transfer is the cost of transmitting data among AWS services. This means that if you move data from, say, an EC2 instance to an S3 bucket, you will be charged for data transfer. The data transfer rate varies based on the type of storage used and the location of the data. For example, the outbound data transfer rate for Amazon S3 to an internet location is $0.09 per GB in the US East (N. Virginia) region. Replication Replication Replication is the process of copying data to multiple locations for redundancy and disaster recovery. Replication can add to your storage costs. The replication price depends on the kind of storage used and the data storage location. disaster recovery The cost of replicating object data to another region in AWS is typically the same as the cost of storing the data in the first place. Here we have a cross-region example with an S3 source bucket in us-east-2. When setting your target replication bucket, you can see the need to enable versioning. This will also incur additional costs that need to be accounted for. Understanding the configuration options that determine your AWS charges is crucial. Monitoring and managing these charges regularly should be included in operational practices and aligned with your business policies. Just S3 alone will have many configuration options.

The cost of the storage tier: Pricing of AWS Storage Tiers Pricing of AWS Storage Tiers The pricing of AWS storage tiers can often be difficult to gauge; nonetheless, there are some fundamental concepts that can help you better comprehend storage pricing. S3 Pricing Model S3 Pricing Model The pricing of S3 is more complex than the pricing of EBS, as it depends on several factors, such as the storage class, the region, the amount of data stored, and the frequency of access. AWS Storage Costs Storage Costs The storage costs for S3 are based on the storage class and the region. For example, the storage cost for a 100 GB object in the S3 Standard storage class in the US East (N. Virginia) region is $0.023 per GB per month. Retrieval Fees Retrieval Fees These fees are incurred when you access data from S3 storage classes that charge for retrieval, such as S3 Infrequent Access and S3 Intelligent-Tiering. The retrieval fee is based on the size of the object and the storage class. For example, the retrieval fee for a 100 GB object from the S3 Infrequent Access tier in the US East (N. Virginia) region is $0.00099 per GB. Data Transfer Costs Data Transfer Costs Data transfer costs are incurred when you move data to or from an S3 bucket. The cost of transferring data depends on the amount of data and the ultimate destination of the data. For example, the data transfer cost for transmitting 100 GB of data from your S3 bucket in the US East (N. Virginia) region to your computer is $0.09 per GB. Here is the pricing of AWS storage tiers to give you some idea of the different tiers and their cost differences. These are point-in-time pricing and may change, of course. You can see nominal pricing differences that line up with associated features and value. Pricing is also adjusted for some regions, in turn affecting cross-region storage. As you scale your storage and overall AWS usage, there may be additional costs associated with transfer, logging, auditing, and other AWS service costs. Understanding the storage pricing of AWS storage tiers is critical in helping you optimize your storage costs and ultimately save money on your AWS bill. optimize your storage costs How to Reduce AWS Storage Costs How to Reduce AWS Storage Costs Optimizing AWS storage costs involves proactive management and strategic decision-making. You can employ these strategies to achieve cost efficiency: Keep EC2 Instances and S3 Buckets in the Same Region Keep EC2 Instances and S3 Buckets in the Same Region By keeping your EC2 instances and S3 buckets in the same region, you reduce data transfer costs and enhance performance. This is particularly useful when applications require frequent data exchange between instances and storage. S3 Replication to Other Regions S3 Replication to Other Regions While replicating data to other regions is vital for disaster recovery, it comes with egress and storage costs. Consider the trade-off between redundancy and cost when determining your replication strategy. N2W’ single user dashboard centralizes and simplifies the process of replicating S3 buckets in order to maximize data protection. Continuously Monitor Which Resources Are Actually Used Continuously Monitor Which Resources Are Actually Used AWS offers several tools to help you monitor your AWS resources, such as Amazon CloudWatch and AWS Cost Explorer. By monitoring your resources, you can identify unused resources that you can terminate to save money. Amazon CloudWatch AWS Cost Explorer Set up Frequent Alerts and Notifications Set up Frequent Alerts and Notifications You can set up alerts and notifications to be notified when your resources are approaching their limits or when they are not being used. This will prevent wasteful spending on resources that are not used. Note that third party tools like N2W allow you to generate alerts and reports to monitor your resource usage and ensure that you are correctly provisioning your resources. Delete Irrelevant Files Delete Irrelevant Files Regularly review your stored data and delete unnecessary files. This not only frees up storage space, but also reduces related expenses. Utilize AWS Cost Explorer Utilize AWS Cost Explorer AWS Cost Explorer is an effective tool that can assist you in visualizing your AWS costs and identifying cost-saving opportunities. Delete Dormant EBS Volumes/S3 Buckets Delete Dormant EBS Volumes/S3 Buckets Amazon EBS volumes and S3 buckets that are not in use can continue to incur charges, so you should delete dormant volumes and S3 buckets to save money. This ought to be included in your data protection and recovery plan so that you are storing dormant volumes and snapshots in an optimized way. Optimizing data protection storage also contributes to your general AWS storage costs. This is where a tool like N2W is critical because you can determine how many disaster recovery copies you want to store (which can be different from the number of backup snapshots) —meaning you don’t have to pay 2x the storage cost to have disaster recovery enabled. a tool like N2W is critical Create Automated EBS Deletion Policies Create Automated EBS Deletion Policies When an EC2 instance is stopped, the EBS volume attached to the instance is also stopped. You can still incur charges for the Amazon EBS volume even if the instance is stopped. EBS does not charge for detached volumes, but storage costs are still incurred. 💡N2W allows you to automatically delete EBS snapshots when archiving to S3/Glacier with our ZeroEBS feature. Keep Default EBS Deletion Policies Keep Default EBS Deletion Policies Make sure that you do not modify the termination behavior of your AWS EBS and EC2. Using the default policy to delete persistent EBS volumes along with the termination of the EC2 instance helps reduce orphaned volumes. Again, this is something that needs to be accounted for in your data retention policies for snapshots and the overall data protection process. Archival From Amazon EBS to Cheaper/Colder Storage Archival From Amazon EBS to Cheaper/Colder Storage If you have data that you do not need to access frequently, you can archive it to a cheaper/colder storage tier, such as S3 Infrequent Access or Glacier. This can help reduce your storage costs. Here’s an overview of the different S3 storage classes that AWS offers: S3 Standard: S3 Standard is the default Amazon S3 storage tier for frequently accessed data. It offers the lowest latency and highest availability.S3 Infrequent Access: The S3 Infrequent Access tier is intended for data that doesn’t need to be available immediately. It offers less expensive storage costs than S3 Standard.S3 Intelligent-Tiering: S3 Intelligent-Tiering automatically moves data between different S3 storage tiers based on access patterns. This can reduce your storage costs without affecting performance.Glacier Instant Retrieval: Glacier Instant Retrieval is a tier of Glacier that offers faster retrieval times than the standard Glacier tier. This is a great option for data that needs to be quickly accessible but isn’t frequently used.Glacier Deep Archive: This is the storage tier within S3 Glacier that provides the lowest cost. It is the best option for data that seldom needs to be accessed. S3 Standard: S3 Standard is the default Amazon S3 storage tier for frequently accessed data. It offers the lowest latency and highest availability. S3 Standard: S3 Infrequent Access: The S3 Infrequent Access tier is intended for data that doesn’t need to be available immediately.
