Components of Cloud Cost 

Now that we know the importance of effective cost management strategies, let us look at the significant components of the overall cloud bill.

Compute Costs

Compute costs are directly related to utilizing computing resources in the cloud, encompassing virtual machines (VMs), containers, and serverless computing platforms. The expenses are determined by the processing power (CPU), memory, and other resources necessary for executing a particular workload.

Factors that influence compute costs include

  • Instance Type: Each VM or container instance type comes with its own cost, depending on its computational capabilities.
  • Running Time: The longer compute resources are provisioned and active, the higher the costs incurred.
  • Reserved Instances vs. On-Demand Instances: Cloud providers commonly offer cost-saving opportunities for customers who commit to reserved instances instead of utilizing on-demand usage.

Storage Costs

The expenses related to storing data in the cloud are called storage costs. These costs are influenced by various factors, including the type of storage utilized, such as object storage (e.g., Amazon S3), block storage (e.g., Amazon EBS), or file storage (e.g., Amazon EFS), as well as aspects like storage capacity and data access patterns.

Several factors contribute to the variation in storage costs:

  • Storage Class: Different storage classes, namely standard, infrequent access, or archival, may have distinct cost structures. The chosen class determines the pricing for storage.
  • Data Replication: Costs can differ based on whether data is stored with redundancy or replication for enhanced durability. Opting for higher levels of replication may result in increased expenses.
  • Data Transfer to and from Storage: Costs may be associated with transferring or retrieving data from storage. These expenses are influenced by the volume of data being transferred.

I/O and Network Costs

I/O (Input/Output) and network expenses refer to the costs of transferring data to and from the cloud. These expenses encompass data transfer between regions, availability zones, or external networks.

Certain factors influence these costs:

  • Data Transfer Volume: The costs associated with data transfer in and out of the cloud tend to increase with the data transfer volume.
  • Data Transfer Across Regions or Availability Zones: Transferring data across different regions or availability zones may result in higher costs.
  • API Calls: Costs can be linked to the number of API calls to access or manage data within the cloud.

Understanding Hidden Cloud Costs

Organizations are charged based on the volume of data stored, meaning the higher the data volume, the higher the cloud bill.

As businesses generate and accumulate more data, the cloud bill escalates accordingly. However, beyond these obvious costs lie unexpected expenses, referred to as hidden costs, associated with cloud storage.

Hidden costs in cloud storage extend beyond the evident charges linked to utilizing these services. These expenses might not be immediately apparent, underscoring the importance for businesses to thoroughly assess their usage patterns and the terms outlined in their cloud service agreements.

The impact of storage costs on the overall cloud bill was further highlighted in a study by Virtana titled “The State of Hybrid Cloud Storage.” Based on interviews with 350 cloud computing decision-makers, the report revealed significant insights into the implications of storage expenses.

The survey findings revealed a staggering 94% acknowledgment of increased storage costs among participants, with 54% confirming faster growth in storage expenses compared to their overall cloud spending.

This underscores the substantial impact of storage costs on organizations' financial health, emphasizing the need for strategic management in this area.

Several hidden costs in cloud storage were identified:

  • Data Transfer Fees: Cloud providers impose charges for data ingress and egress. While uploading data is usually free, retrieving or transmitting data from the cloud may incur additional fees, impacting enterprises with high data transfer needs.
  • Forgotten Instances: Unused cloud resources left active accumulate costs in compute, storage, and network usage, creating financial burdens over time. Regular infrastructure audits are crucial to identify and terminate such instances, minimizing unnecessary expenses.
  • Overprovisioning: Assigning excessive resources to applications leads to paying for underutilized resources, increasing costs. Aligning resources with actual requirements mitigates this inefficiency.

A comprehensive storage audit for major market players showed storage expenses constituting 40% of their total cloud investment. Further investigation into Azure and AWS revealed intriguing insights. For Azure, only 35% of disk storage was utilized, indicating substantial overprovisioning of 65% of disk space.

Similarly, during our analysis within the Amazon Web Services (AWS) cost framework, an interesting finding emerged: 15% of the total cloud expenditure incurred by the company was attributed to the utilization of Elastic Block Store (EBS). Additionally, our observations indicated average disk utilization rate stood at 25%.

In our analysis of various scenarios, organizations experienced downtime at least once per quarter despite overprovisioning their resources to maintain application uptime.

This situation resulted in cloud wastage, characterized by ineffective use or distribution of cloud storage resources, leading to avoidable expenses and underutilized storage capacity. Cloud wastage can take diverse forms, causing businesses relying on cloud storage services to incur unexpectedly high costs.

During comprehensive storage audits for prominent organizations, we identified common issues contributing to cloud wastage, including:

  • Overutilized volumes: These volumes represent storage resources consistently operating at capacity or performance levels exceeding actual workload requirements. They indicate an allocation of storage surpassing the present demand, resulting in increased expenses for organizations paying for resources beyond necessary operational capacity.
  • Idle volumes: This refers to allocated storage resources that remain unused or not accessed. These resources remain inactive despite provisioning, incurring costs without generating value through data-related tasks or processing. Idle volumes contribute to elevated cloud expenses without active utilization.
  • Overprovisioned volume: This occurs when organizations overestimate future storage needs; overprovisioning leads to paying for unused storage capacity. This inefficiency drains financial resources as organizations pay for unutilized space.

So, as we can see, the prominent reason for storage-related costs, regardless of the cloud service provider you are using, is overprovisioning. But this tendency is understandable. 

Effectively managing storage requirements often requires the creation of a custom tool due to the limited range of features provided by Cloud Service Providers (CSPs). However, this tailored approach requires significantly increasing DevOps efforts and time investment. 

Conversely, relying solely on CSP-provided tools may lead to a suboptimal process that is highly manual and resource-intensive, rendering it impractical for daily, continuous use. 

As a result, a dilemma arises wherein over-provisioning becomes an acceptable compromise to ensure uninterrupted uptime of critical applications, considering the significant impact these complexities have on day-to-day business operations. 

However, overprovisioning incurs additional expenses when they have excess or insufficiently utilized storage capacity, resulting in increased costs.

As per a report by StormForge, a significant portion of respondents said that 48% of their cloud spend is being wasted, with over-provisioning and cloud complexity being the leading causes.

Additionally, financial resources that could have been directed towards essential business endeavors are invested in idle storage capacity, indicating a misuse of funds amounting to $17B annually.

  • Underprovisioning: This occurs when organizations allocate insufficient resources for their applications, leading to poor performance, service interruptions, and the need for immediate scaling.
    Such scenarios often result in additional expenses due to adjustments made during peak demand, causing diminished user experiences and increased downtime.
  • Underutilization: This involves the failure to fully exploit the capabilities of cloud services or resources. Organizations invest in advanced features or performance levels but do not configure or utilize them optimally. This underutilization results in missed opportunities to derive the maximum value from cloud services.
  • Failure to implement lifecycle policies: Implementing data lifecycle policies is crucial, yet failure to establish and enforce such policies can have adverse effects. Neglecting to implement these policies results in accumulating outdated data, leading to increased storage costs.
  • Suboptimal Practices in Data Storage: Storing all forms of data in high-performance storage classes, regardless of their access patterns or significance, leads to unnecessary expenses by utilizing premium storage classes for data that could be stored in more cost-effective alternatives.
  • Neglecting Decommissioning of Unused Resources: Failing to decommission or delete storage resources that are no longer required, resulting in ongoing costs for resources that do not actively contribute to business operations.
  • Inefficient Resource Sizing: Neglecting to adjust storage resource sizes based on actual usage patterns and requirements leads to allocating larger storage volumes than necessary and contributing to higher storage costs.
  • Insufficient Monitoring and Optimization: Failure to regularly monitor and optimize storage configurations based on evolving business needs results in missed opportunities to identify and mitigate inefficiencies and continuous wastage.

Understanding and rectifying cloud wastage is paramount. While optimizing computing resources is vital for immediate application performance, neglecting storage efficiency is a common oversight.

Often, organizations prioritize compute expenses due to their direct impact on application responsiveness, inadvertently overlooking the significant impact of storage optimization.

Yet, delving into storage-related factors and optimizing cloud costs are equally crucial. This involves implementing strategies to monitor, analyze, and fine-tune cloud resources, ensuring cost-efficiency across the entire cloud infrastructure.

Proactively addressing hidden storage-related costs and optimizing storage resources can effectively alleviate the financial strain caused by inefficient cloud storage utilization.

Understanding Cloud Storage To Reduce Cloud Cost

The aforementioned hidden cloud costs make it important to understand and implement strategies to reduce the overall cloud cost. But before we dive into strategies to reduce costs associated with cloud storage aspects, we must understand the different types of cloud storage.

  • Block Storage: Although block storage was initially associated with Storage Area Networks (SANs), it has gained widespread popularity within cloud storage ecosystems. Under this model, data is organized into sizable volumes called "blocks," each functioning as an independent hard drive.
    Cloud storage providers utilize these blocks to distribute extensive datasets across multiple storage nodes. Block storage resources offer heightened performance compared to traditional networks, owing to minimal Input/Output (IO) latency, which measures the time to establish a connection between the system and the client.
    This attribute makes block storage especially suitable for demanding applications and large databases hosted in cloud environments.
  • Object Storage: Object storage is an advanced architecture designed specifically for extensive unstructured data repositories. This approach allows for preserving data in its original format while offering the flexibility to customize metadata, enhancing accessibility and analysis capabilities.
    In contrast to traditional file or folder hierarchies, object storage utilizes secure buckets, providing a solid foundation for practically unlimited scalability.
    This storage efficiently accommodates unstructured data and provides cost-effective solutions for managing large volumes of information.
    By eliminating rigid file structures and leveraging the scalability of secure buckets, object storage becomes an adaptable and economical choice for organizations dealing with substantial and diverse datasets.
  • File Storage: Often known as file-based storage, it is widely used in various applications. It arranges data in a hierarchical structure of folders and files, making it a preferred choice.
    This storage method is commonly used with network-attached storage (NAS) servers. It relies on popular file-level protocols like Server Message Block (SMB) for Windows and Network File System (NFS) for Linux.
    The familiar organization of file storage enables efficient management and access to data on different platforms and operating systems.

Factors Affecting Block Storage Cost

Now that we know the different types of cloud storage, let us look at their pricing components and hidden cloud costs. Beginning with block storage, a range of factors determine the pricing structure of block storage, and users are invoiced according to their usage of these features.

  • Volume Type and Storage Size: EBS offers a variety of volume types that are optimized for different use cases, including General Purpose (SSD), Provisioned IOPS (SSD), Cold HDD, Throughput Optimized HDD, and Magnetic.
    The storage size denotes the capacity of the EBS volume. Each volume type has its own cost per gigabyte, with larger volumes generally incurring higher expenses. Users select the appropriate volume type based on their applications' performance and storage requirements.
  • Provisioned Throughput: Provisioned Throughput is a capability that enables users to allocate a specific level of throughput, measured in megabytes per second (MB/s), for their EBS volumes.
    In addition to the standard storage costs, users are billed for the provisioned throughput. This feature is particularly valuable when applications require a consistent and predictable throughput.
  • Provisioned IOPS: The feature of Provisioned IOPS (Input/Output Operations Per Second) allows users to allocate a specific number of IOPS for their EBS volumes, ensuring consistent and reliable performance. In addition to the standard storage costs, users have to bear additional expenses for the provisioned IOPS. This feature proves beneficial for applications that demand high and predictable I/O performance.
  • Total Snapshot Size: EBS allows users to create point-in-time snapshots of their volumes for purposes like backup and recovery. The total snapshot size represents the combined size of all the snapshots associated with a particular volume. Users are obligated to pay for the storage space utilized by these snapshots. By storing only the changed data since the last snapshot, incremental snapshots help minimize costs related to ongoing snapshot storage.

While these components profoundly impact the cloud bill, it is essential to note that the cloud-specific pricing and type of block storage volume change with time. Hence, it would be advisable to check the pricing page.

Now that we know the different pricing factors in block storage, it is essential to understand its hidden costs before we move ahead with optimization.

  • Data transfer costs: Cloud providers often have fees for transferring data between regions, availability zones, or external networks. These costs can accumulate if applications need to transfer data frequently, especially across various geographical locations.
  • Cross-region replication costs: When replicating data across different regions for redundancy or disaster recovery purposes, there are additional storage and data transfer expenses.
  • Change in storage cost: Certain cloud providers offer multiple storage classes at different prices. If there is a change in data access patterns and a need to move data to another storage class, the migration process can result in expenses.
  • API request cost: API requests made to manage and access block storage may be subject to charges by cloud providers. Making frequent or inefficient use of API calls can lead to unexpected costs.

Ways To Optimize Block Storage

    For instance, switching objects between different storage classes or automatically deleting expired data could attract charges.

Ways To Optimize Object Storage

Mentioned below are some ways you can optimize object storage to reduce overall cloud costs.

S3 Intelligent Tiering

AWS S3 Intelligent Tiering presents a cost-effective storage solution within the AWS S3 ecosystem. It automates data organization across different storage tiers, eliminating the need for manual object management and reducing the risks of human error.

Unlike other storage choices, AWS S3 Intelligent Tiering does not add additional costs for accessing objects. Instead, users are only charged a minimal fee of $0.0025 per 1,000 objects for monitoring and automation. The total cost of cloud storage depends on the tier assigned to the data, which can include archival tiers if required.

By utilizing S3 Intelligent Tiering, startups, and AWS users can avoid unnecessary expenses associated with AWS S3 storage. Many users typically default to the standard S3 Storage tier, resulting in potential overpayments of up to 70%. S3 Intelligent Tiering is vital in optimizing AWS S3 costs, ensuring that data resides in the most cost-efficient storage tier, ultimately leading to significant savings.

Lifecycle Management

AWS S3 Lifecycle policies provide an automated framework that helps manage the lifecycle of objects within your S3 storage. This framework offers various advantages, including cost optimization, improved data protection, and ensuring compliance by defining how objects transition between storage tiers or specifying deletion timelines.

By utilizing AWS S3 lifecycle policies, you have precise control over the timing of object transitions between storage tiers. This allows for effortless movement of infrequently accessed data to archival S3 tiers.

Moreover, the inherent automation in these policies facilitates the identification of objects set for expiration or deletion, eliminating the need for manual oversight.

The implementation of AWS S3 Lifecycle policies brings two significant benefits. Firstly, it enables automatic cost reduction as data becomes less relevant to your application.

When data becomes older or is accessed less frequently, it can be automatically shifted to more economical storage layers, leading to noticeable cost savings. Additionally, the automated process minimizes the possibility of human mistakes, ensuring that less critical data does not remain in expensive storage tiers.

Monitoring And Alerts

Like for optimizing block storage, you can use CloudWatch alerts to monitor usage metrics. By leveraging this tool, you can gain real-time visibility into your S3 usage and receive prompt alerts whenever certain conditions are fulfilled.

This proactive methodology empowers you to tackle potential concerns swiftly, thus guaranteeing optimal performance and cost-efficiency for your S3 storage.

Take, for instance, to ensure timely awareness of your S3 bucket's storage capacity nearing a predetermined threshold, an alarm can be established using the S3 bucket size metric.

This alarm will facilitate notifications whenever the storage size approaches or surpasses the predefined capacity. Such proactive monitoring mitigates the risks of reaching storage limits, enabling smooth operations.

Another example of how CloudWatch alerts can help you monitor usage metrics is to ensure prompt notification about any sudden spike in S3 request latency; you can configure CloudWatch alarms for latency metrics.

This proactive measure enables timely identification of performance concerns and facilitates necessary remedial steps. For instance, you can investigate the underlying cause or optimize your S3 configurations to enhance overall performance.

Furthermore, you can also enable Cost Explorer or download reports about your S3 buckets to stay informed about your usage costs.

AWS Cost Explorer is an Amazon Web Services (AWS) tool that enables users to effortlessly visualize, comprehend, and examine their AWS expenditures and utilization throughout a specified duration. It offers the following features.

  • Cost visualization: The cost breakdown feature presents a comprehensive view of expenses across various services, including S3. With this, you can quickly determine the amount allocated to storage, data transfer, and other associated S3 services, ensuring transparency in your expenditure.
  • Cost forecasting: The AWS Cost Explorer offers a tool that utilizes past data to estimate your forthcoming AWS expenses. This valuable feature aids in effective planning and budgeting for your S3 usage.
  • Cost alerts: You can establish alerts according to specific cost or usage limits to ensure cost efficiency and control. For S3, these alerts allow you to monitor and detect sudden spikes in storage expenses or data transfer costs.
  • Report: You can generate and save personalized reports that thoroughly analyze your S3 usage and associated expenses. These reports can be customized by employing time range, service, region, and tags.
    You can obtain more detailed and in-depth insights by applying filters and organizing data into distinct dimensions, such as AWS region, S3 storage class, or tags.

Strategic Object Storage Bucket And Instance Alignment

For optimal cost management and up-to-date information, it is advisable to consolidate your Amazon S3 buckets with your Amazon EC2 instances in the same AWS region.

When these instances and buckets are located in different areas, not only does it result in higher data transfer expenses, but it also introduces performance drawbacks. To address these concerns, ensure that both services are configured within a unified AWS region, enabling cost-efficient and unhindered data exchange.

S3 Versioning Optimization

S3 versions offer valuable benefits such as data protection, compliance support, and recovery from accidental deletions or overwrites—however, AWS charges for every version of a data object that is stored and transferred.

You will be billed for them all if you have multiple versions of an object. In the following ways, you can prevent increased object storage costs due to S3 versioning.

  • Implement lifecycle policies: Define and execute lifecycle policies that enable the automated transition or deletion of object versions according to your specific needs. By effectively managing the lifecycle of object versions, you can effectively manage storage costs.
  • Review object versions: Regularly assess the versions of objects stored in your S3 bucket and determine if older versions can be securely deleted or shifted to a storage class with lower costs.
  • Consider S3 intelligent tiering: If you encounter varying access patterns for different object versions, you should utilize S3 Intelligent Tiering. This feature automatically adjusts the access tiers of objects based on changing access patterns, potentially optimizing costs.

Bulk Uploading Of Objects

The data size does not determine the cost of using the Amazon S3 API but rather the type of API call used. The cost remains the same whether you upload a large or small file.

However, the overall cost can quickly increase if you upload multiple small files. To minimize this cost, a practical solution is combining multiple small objects into one file with the tar utility.

This allows for bulk uploads instead of incremental chunks, reducing the number of S3 API calls and, subsequently, reducing overall costs. This approach optimizes the efficiency of data transfer operations and promotes a more cost-effective use of Amazon S3 resources.

How Did We Help Uniguest Identify Its Hidden Cloud Wastage Factors?

Now you know some of the most effective strategies to optimize your block and object storage and cut down on overall cloud bills. Let us show you how Lucidity helped one of many organizations identify cloud wastage and take prompt actions to reduce overall cloud bills.

Uniguest, a prominent company specializing in digital signage and engagement technology, had relied on Azure as their chosen cloud service provider for quite some time.

However, effectively managing the complexities of their cloud storage environment became a significant challenge for them. To enhance their cloud cost optimization efforts, they approached us with a specific obstacle: the urgent requirement for comprehensive visibility into their storage parameters.

Gathering utilization data individually from various disk drives had become arduous, and the prospect of deploying costly monitoring tools only added to their concerns. Recognizing the labor-intensive nature of manually tracking storage usage, we took it upon ourselves to conduct a thorough audit.

We deployed Lucidity Storage Audit, an easily accessible and preconfigured tool that simplifies the storage auditing process. By leveraging Azure's internal services, Lucidity Audit provided essential insights into disk usage and health, enabling smooth cost optimization and prevention of downtime.

With just one click, our agentless audit process uncovered a shocking overspend of up to 71% in Uniguest's Azure storage. The main culprit behind this excessive expenditure was the under-utilization or over-provisioning of resources, accounting for 95% of the wastage.

On average, disk utilization stood at a mere 22%. The remaining 5% comprised idle and unused resources, primarily caused by storage that was either not connected to a virtual machine or associated with a stopped VM.

We leveraged the audit report to implement Lucidity Auto Scaler—an agent-based architecture with an auto-scaler that is an additional layer over Azure's cloud infrastructure. 

The deployment process of the auto-scaler was straightforward, requiring just three clicks. Once activated, it seamlessly adjusted storage capacities, optimizing disk utilization within a targeted 70-80% range. 

This proactive strategy proved instrumental in drastically reducing overall storage costs while providing the agility to accommodate workload spikes or sudden surge in traffic effortlessly. We achieved this by rapidly expanding disk storage within a mere minute.

The outcome was exceptional, with a 59% decrease in storage expenses and a significant improvement in disk utilization, bringing it within the targeted range of 75%-80%. This demonstrated that Lucidity optimized costs and ensured optimal resource utilization within Uniguest's Azure environment.

Proactive Cloud Management For Enhanced Efficiency
