Organizations often expect to cut costs when migrating IT infrastructure from on-premises setups to the cloud. However, the reality can be starkly different. Various cost traps can emerge during cloud transformation, leading to unexpectedly high expenses if not carefully managed.
In this article, we will explore the most common cloud cost traps and provide strategies to avoid cloud expenditures during cloud transformation.
Estimating Cloud Transformation Expenses
Forecasting expenses during a cloud transformation can be challenging. In traditional IT setups, cost estimation is relatively straightforward, encompassing fixed costs such as data center rent, hardware, and licenses. Conversely, in a cloud environment, you pay based on usage, which can fluctuate greatly, complicating cost predictions.
This variability often leads to unforeseen cost spikes during cloud transformation.
At Gart Solutions, we help numerous organizations navigate their cloud transformation journeys and frequently encounter five key mistakes that can drive up costs.
Common Cloud Costs Optimization Traps Happening There:
1. The "Lift and Shift" Approach
A common mistake is migrating existing setups to the cloud without modifications, known as a "lift and shift." This method usually leads to high costs because it fails to leverage the cloud's unique advantages.
Instead, organizations should modernize their solutions through "refactoring." Refactoring involves changing or completely replacing applications or systems to exploit the cloud's benefits such as scalability, elasticity, self-service, and measurability. By optimizing resources for the cloud, organizations can achieve greater flexibility, efficiency, and cost savings.
2. Choosing the Wrong IT Architecture Setup
Selecting the right architecture for a cloud environment is critical. IT architecture must be carefully planned to maximize cloud benefits. Determining how services interact and which ones to use requires an architecture tailored to the organization’s needs. Poor architectural choices can result in an environment that does not meet security and scalability requirements, leading to costly adjustments. Hence, it's vital to seek expert advice, critically review recommendations, and explore alternatives that do not compromise functionality or performance.
Contact Gart & get the IT Infrastructure Consulting. Quick and long-term wins are guaranteed.
3. Overreliance on Enterprise Versions
Organizations often default to enterprise versions of cloud services without assessing their actual needs. This can result in unnecessarily high costs. Before opting for enterprise versions, it's crucial to evaluate if standard versions can meet the requirements.
Contact Gart & assess cloud services carefully.
4. Uncontrolled Capacity Planning
Accurately predicting capacity needs is a common challenge, where previous expertise is needed. Capacity requirements can vary — constant for some, linear for others, exponential for a third, and seasonal for a fourth. These variations can lead to over- or under-provisioning of resources, resulting in additional costs. Effective capacity planning involves basic estimates and continuous monitoring to detect changes in needs and adjust resources accordingly. Utilizing the built-in capabilities of cloud services for business alignment requires the right expertise.
Contact Gart to assess your resources and requirements and make optimal capacity planning.
5. Lack of Appropriate Skills
Cloud transformation increases IT delivery complexity and requires new skills. Without the right expertise, projects can become inefficient, leading to wrong decisions and increased costs.
Contact Gart - we are the trusted partner in cloud consulting, migration, and cost optimization.
6. Underestimating Data Transfer Costs
One often overlooked cost trap is data transfer. While moving data to the cloud might seem straightforward, the costs associated with data egress (data leaving the cloud) can be substantial. Organizations should be aware of these charges and plan data transfer strategies accordingly, such as optimizing data placement and minimizing data transfer needs.
7. Neglecting Long-term Cost Implications
Focusing solely on immediate cost savings can lead to higher long-term expenses. Organizations should consider the long-term implications of their cloud choices, including potential costs associated with scaling, maintenance, and upgrades. A comprehensive cost-benefit analysis that includes future scenarios can help in making more informed decisions.
8. Ignoring Security and Compliance Costs
Security and compliance are critical in cloud environments, and neglecting these aspects can lead to significant expenses. Ensuring that cloud deployments comply with regulatory standards and implementing robust security measures can prevent costly breaches and fines. Investing in security tools and expertise upfront is crucial for avoiding unexpected costs later.
Contact for consulting in security, architecture, and cloud technologies. Prevent unnecessary expenses and ensure a smooth transition.
9. Failing to Monitor and Optimize Usage
Continuous monitoring and optimization of cloud usage are essential for controlling costs. Without proper monitoring, organizations can easily overspend on unnecessary resources. Utilizing cloud management tools and implementing policies for regular audits and optimizations can help keep costs in check.
10. Overlooking Vendor Lock-in Risks
Vendor lock-in occurs when an organization becomes overly dependent on a single cloud provider, making it difficult and costly to switch providers. To mitigate this risk, organizations should adopt a multi-cloud strategy or ensure that their architecture allows for flexibility and portability across different cloud platforms.
11. Underutilizing Reserved Instances and Savings Plans
Cloud providers offer reserved instances and savings plans that can significantly reduce costs for predictable workloads. However, many organizations fail to take advantage of these options. By analyzing usage patterns and committing to long-term plans, organizations can achieve substantial savings compared to on-demand pricing.
12. Over-Provisioning Resources
Over-provisioning, or allocating more resources than needed, is a common cost trap. This often results from a lack of understanding of actual usage requirements. Implementing auto-scaling and right-sizing strategies can help in dynamically adjusting resources based on real-time demand, thus avoiding unnecessary expenses.
13. Lack of Governance and Policies
Effective governance and policies are crucial for managing cloud costs. Without proper governance, organizations can face uncontrolled spending and resource mismanagement. Establishing clear policies for resource usage, cost allocation, and accountability ensures that cloud resources are used efficiently, and costs are kept under control.
14. Neglecting to Decommission Unused Resources
Failing to decommission unused or idle resources can lead to wasted spending. Regularly reviewing and cleaning up unused instances, storage, and other resources can help in reducing unnecessary costs. Automation tools can assist in identifying and decommissioning these resources.
15. Ignoring Cloud Cost Management Tools
Most cloud providers offer cost management and optimization tools, but organizations often overlook these valuable resources. Utilizing these tools can provide insights into spending patterns, help identify cost-saving opportunities, and enable more effective budgeting and forecasting.
16. Misjudging Data Storage Costs
Data storage costs can add up quickly, especially if organizations do not manage their data efficiently. Implementing data lifecycle policies, such as archiving old data and deleting redundant data, can help control storage costs. Additionally, selecting the appropriate storage class based on access frequency and performance needs is essential.
17. Overlooking Software Licensing Costs
Cloud transformation can sometimes lead to increased software licensing costs, particularly if organizations do not review their licensing agreements carefully. It's important to understand the licensing implications of moving to the cloud and to negotiate contracts that align with cloud usage patterns.
18. Inadequate Backup and Disaster Recovery Planning
Backup and disaster recovery are critical components of cloud strategy, but inadequate planning in these areas can lead to unexpected costs. Organizations should ensure that their backup and recovery plans are cost-effective and align with their overall cloud strategy. This includes selecting the right tools and services for efficient data protection and recovery.
19. Failing to Leverage Cloud Provider Discounts
Cloud providers often offer discounts for committed usage, volume purchases, and other incentives. Failing to leverage these discounts can result in higher costs. Organizations should actively seek out and take advantage of available discounts to optimize their cloud spending.
Contact Gart and calculate cloud discounts for your case.
20. Not Considering Hidden Costs
Hidden costs, such as those related to network latency, data retrieval, and specialized support, can significantly impact the overall cloud budget. Organizations should thoroughly assess all potential costs, including those that may not be immediately apparent, to avoid budget surprises.

Exploring the Landscape of IaC Tools
The IaC paradigm is widely embraced in modern software development, offering a range of tools for deployment, configuration management, virtualization, and orchestration. Prominent containerization and orchestration tools like Docker and Kubernetes employ YAML to express the desired end state. HashiCorp Packer is another tool that leverages JSON templates and variables for creating system snapshots.
The most popular configuration management tools, namely Ansible, Chef, and Puppet, adopt the IaC approach to define the desired state of the servers under their management.
Ansible functions by bootstrapping servers and orchestrating them based on predefined playbooks. These playbooks, written in YAML, outline the operations Ansible will execute and the targeted resources it will operate on. These operations can include starting services, installing packages via the system's package manager, or executing custom bash commands.
Both Chef and Puppet operate through central servers that issue instructions for orchestrating managed servers. Agent software needs to be installed on the managed servers. While Chef employs Ruby to describe resources, Puppet has its own declarative language.
Terraform seamlessly integrates with other IaC tools and DevOps systems, excelling in provisioning infrastructure resources rather than software installation and initial server configuration.
Unlike configuration management tools like Ansible and Chef, Terraform is not designed for installing software on target resources or scheduling tasks. Instead, Terraform utilizes providers to interact with supported resources.
Terraform can operate on a single machine without the need for a master or managed servers, unlike some other tools. It does not actively monitor the actual state of resources and automatically reapply configurations. Its primary focus is on orchestration. Typically, the workflow involves provisioning resources with Terraform and using a configuration management tool for further customization if necessary.
For Chef, Terraform provides a built-in provider that configures the client on the orchestrated remote resources. This allows for automatic addition of all orchestrated servers to the master server and further customization using Chef cookbooks (Chef's infrastructure declarations).

Popular Infrastructure as Code Tools
Terraform
Terraform, introduced by HashiCorp in 2014, is an open-source Infrastructure as Code (IaC) solution. It operates based on a declarative approach to managing infrastructure, allowing you to define the desired end state of your infrastructure in a configuration file. Terraform then works to bring the infrastructure to that desired state. This configuration is applied using the PUSH method. Written in the Go programming language, Terraform incorporates its own language known as HashiCorp Configuration Language (HCL), which is used for writing configuration files that automate infrastructure management tasks.
Download: https://github.com/hashicorp/terraform
Terraform operates by analyzing the infrastructure code provided and constructing a graph that represents the resources and their relationships. This graph is then compared with the cached state of resources in the cloud. Based on this comparison, Terraform generates an execution plan that outlines the necessary changes to be applied to the cloud in order to achieve the desired state, including the order in which these changes should be made.
Within Terraform, there are two primary components: providers and provisioners. Providers are responsible for interacting with cloud service providers, handling the creation, management, and deletion of resources. On the other hand, provisioners are used to execute specific actions on the remote resources created or on the local machine where the code is being processed.
Terraform offers support for managing fundamental components of various cloud providers, such as compute instances, load balancers, storage, and DNS records. Additionally, Terraform's extensibility allows for the incorporation of new providers and provisioners.
In the realm of Infrastructure as Code (IaC), Terraform's primary role is to ensure that the state of resources in the cloud aligns with the state expressed in the provided code. However, it's important to note that Terraform does not actively track deployed resources or monitor the ongoing bootstrapping of prepared compute instances. The subsequent section will delve into the distinctions between Terraform and other tools, as well as how they complement each other within the workflow.

It provides a robust configuration management framework, allowing users to define desired states for infrastructure resources and ensure their continuous enforcement.
SaltStack is designed to handle massive infrastructures efficiently, making it suitable for organizations with complex and distributed environments.
The SaltStack solution stands out compared to others mentioned in this article. When creating SaltStack, the primary goal was to achieve high speed. To ensure high performance, the architecture of the solution is based on the interaction between the Salt-master server components and Salt-minion clients, which operate in push mode using Salt-SSH.
The project is developed in Python and is hosted in the repository at https://github.com/saltstack/salt.
The high speed is achieved through asynchronous task execution. The idea is that the Salt Master communicates with Salt Minions using a publish/subscribe model, where the master publishes a task and the minions receive and asynchronously execute it. They interact through a shared bus, where the master sends a single message specifying the criteria that minions must meet, and they start executing the task. The master simply waits for information from all sources, knowing how many minions to expect a response from. To some extent, this operates on a "fire and forget" principle.
In the event of the master going offline, the minion will still complete the assigned work, and upon the master's return, it will receive the results.
The interaction architecture can be quite complex, as illustrated in the vRealize Automation SaltStack Config diagram below.
When comparing SaltStack and Ansible, due to architectural differences, Ansible spends more time processing messages. However, unlike SaltStack's minions, which essentially act as agents, Ansible does not require agents to function. SaltStack is significantly easier to deploy compared to Ansible, which requires a series of configurations to be performed. SaltStack does not require extensive script writing for its operation, whereas Ansible is quite reliant on scripting for interacting with infrastructure.
Additionally, SaltStack can have multiple masters, so if one fails, control is not lost. Ansible, on the other hand, can have a secondary node in case of failure. Finally, SaltStack is supported by GitHub, while Ansible is supported by Red Hat.
