Choosing the most cost-effective storage option optimizes expenses for different data types. Moreover, the flexibility extends beyond storage to computational resources, enabling efficient management of fluctuating workloads without hefty initial hardware investments.

The benefits of cloud computing are indisputable in terms of speeding up innovation and market entry. However, these advantages are counterbalanced by significant challenges, notably the increasing costs associated with cloud services. A G2 report unveiled that organizations waste a staggering 32% of their cloud expenditure. A significant majority (54%) attribute this excessive spending to a lack of clear insight into their usage and efficiency. This underscores the critical need to comprehend how cloud resources are utilized and optimized. Organizations might inadvertently overspend on cloud services without a holistic understanding of usage patterns and resource efficiency. This stark reality emphasizes the pivotal role of adopting strategies and tools that enhance visibility and control over cloud expenditure.

But before we dive into cloud cost optimization strategies, let us talk about cloud expenditure and try to understand the loopholes within cloud expenditure that lead to cloud waste. A thorough comprehension of cloud spending and minimizing unnecessary expenses is essential for efficient cloud cost optimization. This knowledge enables organizations to exercise control over costs, enhance the efficiency of resources, boost performance, and make well-informed decisions that align with their business objectives.

Cloud expenditure encompasses the overall financial resources an organization allocates towards procuring cloud computing services and resources from cloud service providers. It encompasses expenses related to utilizing diverse cloud services, including compute capabilities, storage, networking, databases, and other essential infrastructure elements. It serves as a tangible representation of a business's monetary commitment toward harnessing the advantages offered by cloud computing.

Cloud computing has transformed how IT budgets are allocated, shifting from the traditional Capital Expenditure (CapEx) model to a more predictable and adaptable Operational Expenditure (OpEx) model.

Earlier, there was only one way of paying for the IT infrastructure: an upfront capital expense, known as the CapEx model. To facilitate business operations, IT managers must acquire physical servers, racks, network connections, hardware components, and other infrastructure essentials such as storage space, facilities, cooling systems, and associated software. Even before the systems were operational, the business had already spent considerable capital on procuring all these resources, only to repeat the process in the subsequent refresh cycle.

The emergence of cloud-based technology solutions delivered "as a service" has revolutionized the operations of the IT industry. This transformation is primarily driven by adopting cloud-based technology solutions delivered as services. It has transformed the financial aspect from a traditional capital expense (CapEx) model to an operational expense (OpEx) framework. 

Unlike the conventional approach, companies are no longer burdened with upfront costs for purchasing hardware or software. Instead, they embrace a pay-as-you-go model, similar to paying utility bills, enabling a more predictable pattern of monthly IT expenses. This significant change eliminates the need for large upfront investments, replacing them with easily manageable and predictable monthly fees. Consequently, businesses only incur additional costs when they utilize more resources, allowing them to efficiently scale their cloud computing capabilities along with their evolving operational needs.

IT managers increasingly recognize the strategic value embedded in these ongoing smaller costs, which departs from the cyclic nature of infrastructure builds. This change in perspective plays a crucial role in enhancing the overall value brought to the business.

By effectively managing costs and entrusting the responsibility of infrastructure management to third-party providers, IT departments can redirect their focus toward more strategic endeavors.

However, transitioning from the traditional capital expenses (CapEx) model of building your own data center to the operational expenses (OpEx) public cloud model is not a magical solution for cost-saving purposes. As per a report by Flexera, cloud waste averaged 30% in 2021, which increased to 32% by 2022. While this 2 percent does not mean much, it could mean massive wastage of cloud spend when calculated. Owing to the challenges associated with OpEx, many organizations face challenges managing cloud costs, leading to cloud waste. Below are some of the difficulties with OpEx that have resulted in cloud wastage.

• Unpredictability: The cloud cost model of Operational Expenses (OpEx) lends flexibility and scalability to cloud computing. However, it also brings inherent unpredictability to the financial aspect. Under the OpEx model, businesses are invoiced based on their real resource utilization, resulting in fluctuating costs that are difficult to anticipate.
• Insufficient Visibility and Monitoring: According to a report by Anodot, 54% of the respondents said their cloud wastage stems from the lack of visibility into cloud costs. Insufficiency in observing and overseeing cloud usage can result in suboptimal allocation of resources. The absence of appropriate monitoring tools poses a challenge in identifying unused or underutilized resources, ultimately leading to avoidable expenditures.
• Inefficient Resource Allocation: Inadequate optimization can result in inefficient resource distribution and overprovisioning or underutilization. Businesses might allocate excessive resources or neglect to downscale when demand decreases, thus incurring unnecessary expenditures. The 2022 State of Cloud Intelligence Report revealed that 7 out of 10 organizations struggled to allocate costs effectively as they were unsure what, why, and who drives the costs.

Considering the aforementioned, it becomes paramount that understanding the intricacies associated with cloud expenditure, like the OpEx model and the subsequent cloud wastage due to prevalent loopholes, is necessary to optimize cloud cost. An approach that grasps the concept of cloud expenditure and tackles cloud waste guarantees that businesses can fully leverage the advantages of cloud computing while maintaining financial prudence. This is where cloud cost optimization comes into the picture.

Tips For Cloud Cost Optimization

Now that we know the significance of cloud cost optimization let us talk about the strategies that will help reduce the overall cloud costs. 

1. Understand The Cloud Bill

The first step to effective cloud cost optimization is understanding what makes the cloud bill, aka the components. 

Compute costs: Compute expenses are a significant part of cloud spending. Cloud providers primarily offer compute capabilities by partitioning servers into smaller virtual machines (VMs) via a hypervisor. These VMs have robust resources, boasting hundreds of CPUs and storage capacities that often reach thousands of gigabytes (GBs) for both RAM and storage.

Each cloud provider offers various unique VM options, providing various configurations to suit diverse workload requirements. This flexibility allows users to select a specific VM setup tailored to their needs. Factors like RAM and CPU allocation are crucial in making these decisions, ensuring optimized resource utilization aligned with workload demands.

Storage costs: Cloud storage is a fundamental and economically advantageous service within cloud computing, serving as a flexible and user-friendly platform for storing and managing data. Cloud service providers have tailored a range of services to meet the diverse storage needs of modern businesses focused on cloud solutions. These services are diverse across various cloud providers.

There are primarily two types of storage services: block storage and object storage. Block storage operates with fixed-sized blocks, offering precise data management capabilities. It's well-suited for applications demanding fast and high-performance storage solutions. For instance, Amazon EBS (Elastic Block Storage) is a vital storage component for Amazon EC2 instances, furnishing essential storage capabilities.

Similarly, Azure Virtual Disks operate on a block storage architecture closely associated with Azure Virtual Machines in the Azure ecosystem. Azure offers Managed Disks, a distinct type of Virtual Disk surpassing traditional Azure Virtual Disks and Amazon EBS in terms of flexibility and simplified backup procedures.

Pricing for AWS and Azure varies across regions. To provide a clearer understanding, let's delve into the prices in comparable regions within the US.

Amazon EBS and Azure offer different pricing structures for their storage solutions, catering to varying storage needs.

Amazon EBS presents two pricing options: $0.045 per GB for HDD (Hard Disk Drive) and $0.10 per GB for SSD (Solid State Drive). The costs for increased IOPS (Input/Output Operations Per Second) scale accordingly. Additionally, the free tier includes a complimentary 30 GB of SSD storage, a notable benefit.

Azure's virtual disks are priced at $0.05 per GB for HDD, while SSDs are available at $19.71 monthly for 128 GB. These pricing models delineate the nuanced differences between Amazon EBS and Azure virtual disks, showcasing distinct considerations and offerings from each cloud provider in their storage solutions.

On the other hand, object storage is well-suited for managing unstructured data and serves as scalable storage for substantial information repositories.

In our research exploring the impact of storage on overall cloud expenditure, a Virtana report provided substantial insights. Out of 350 Cloud decision-makers surveyed, a staggering 94% noted a noticeable increase in storage expenses. Alarmingly, 54% of respondents confirmed that their spending on storage was rising at a rate surpassing the overall growth in their cloud bills. These findings underscore the significant financial implications for organizations due to escalating storage costs.

In our pursuit to investigate the financial implications of storage resources further, we made an interesting discovery concerning Azure and AWS cloud service providers. Cloud storage plays a substantial role in the overall expenses involved in cloud services. 

Notably, our examination of Azure revealed that a mere 35% of disk storage is actively utilized, indicating an excess provisioning of 65% of disk space.

During our analysis conducted within the Amazon Web Services (AWS) cost framework, we made an intriguing discovery. The utilization of Elastic Block Store (EBS) accounted for 15% of the company's overall cloud expenditure. Furthermore, our observations revealed that the average disk utilization rate reached 25%.

Optimizing storage resources is equally crucial in minimizing the overall cloud expenses. Often, organizations prioritize optimizing compute resources due to their direct impact on applications and services. Compute resources are closely associated with immediate performance gains, prompting organizations to prioritize enhancement to ensure efficient application execution.

Unfortunately, storage optimization tends to receive less attention, partly because its effects on performance might not be as immediately visible as those of compute resources. The lack of visibility and straightforward monitoring tools for storage can also contribute to this oversight. When faced with limitations in time and resources, organizations tend to focus on more observable aspects, potentially neglecting the monitoring and optimization of storage resources.

However, overlooking storage optimization can lead to increased costs over time, especially as data grows unchecked. The expenses associated with storing larger volumes of data can significantly impact the overall cloud bill. Therefore, to achieve maximum cost benefits, it's crucial to equally emphasize optimizing compute and storage resources when optimizing cloud costs.

Bandwidth costs: Understanding bandwidth costs within cloud services is crucial as it encompasses expenses associated with data transfer across the provider's services and the Internet and between various regions or availability zones within the provider's infrastructure.

These costs can significantly contribute to the overall expenditure for applications or services heavily reliant on data transfer over the Internet. Additionally, if your infrastructure spans multiple regions or availability zones within the cloud provider's network, additional expenses might incur for transferring data between these locations.

Discounts and savings: Cloud providers often offer discounts, savings plans, or reserved instances as ways to help customers save money. These options can be advantageous if you commit to using specific resources for defined periods. Maximizing these cost-saving opportunities requires thoroughly understanding and optimizing your usage patterns.

2. Use The Right Storage Options

Once you grasp the key components of a cloud bill, determining the most suitable storage options for your business becomes pivotal. Cloud service providers typically offer three primary storage options: object, file, and block storage, each designed for specific purposes. Let's delve into the distinct use cases where object, file, and block storage excel.

3. Identify Unused And Unattached Resources

Once you clearly understand which storage option would best suit your business, it is time to dive deeper into what is leading to the unexpected cost. 

Idle storage resources: We conducted a storage audit on a few organizations and discovered that idle resources were the cause of wastage. This was either due to the disk not being attached to a virtual machine or it being attached to a stopped VM. These resources are currently not utilized and persistently consume storage, having no role in any processing or business operations. Idle resources can result in hefty expenses. Some ways you might be paving the way for idle and unused resources are.

• Manual Resource Management: Manual resource management can inadvertently lead to instances or storage being left running unintentionally.
• Overprovisioning: Organizations often allocate excessive resources to guarantee availability during peak demand. However, these resources may remain idle during periods of low demand. Moreover, our research above found that despite overprovisioning, organizations faced at least downtime every quarter. 

But why do organizations overprovision their resources?

Achieving the utmost efficiency in storage often requires developing a tailor-made solution, as Cloud Service Providers (CSPs) offer limited advanced features. However, implementing this custom tool involves significant dedication from DevOps teams and a considerable time investment. Conversely, relying solely on CSP-provided tools can lead to a labor-intensive and resource-heavy process, despite its lack of efficiency, becoming a necessary routine.

As a result, organizations may feel compelled to allocate excess resources to ensure uninterrupted application uptime. This decision arises from recognizing the tangible impact such excessive resource allocation has on everyday business operations.

However, this inefficient resource management and overprovisioning lead to drastic cost-related impacts. Aside from contributing to higher operational costs, idle resources can also lead to budget overruns, with the cost accumulating for resources not being actively used to achieve any business objective. 

Idle compute resources: Like idle storage resources, organizations also have idle compute resources, which can be described as virtual machines, instances, or other computational elements that have been provisioned and allocated but are presently not engaged in executing substantial work or processing tasks. Just like idle storage resources, they result from inadequate resource management and overprovisioning, and they also increase operation costs and cause budget overrun. 

The aforementioned makes identifying and minimizing idle and unwanted resources a significant portion of cloud cost optimization. You can follow the tips below to eliminate idle and unwanted resources.

Monitoring

To ensure efficient storage management, regularly observe the utilization of your storage volumes and compute resources. To effectively optimize your cloud environment, it is essential to consistently monitor resource utilization using cloud monitoring tools equipped with alert notifications. Monitor critical metrics like CPU usage, disk usage, disk I/O, bandwidth, and memory usage. Identify any resources that consistently show minimal usage, suggesting they may be idle, and consider downsizing or removing them to enhance the efficiency of your cloud setup. 

There are numerous native cloud optimization tools like AWS CloudWatch and AWS Cost Explorer and third-party tools like CloudHealth by VMWare or CloudSpend by CloudZero, which can help identify idle and unwanted compute resources.
