Welcome to today’s blog, where we’re diving into some of the common pitfalls that teams encounter when architecting for the cloud — and, more importantly, how to avoid them! As more businesses make the move to cloud platforms like AWS, Google Cloud, and Azure, it’s easy to assume that simply shifting workloads to the cloud will automatically improve performance and save costs. But without careful planning, cloud projects can quickly become complex, costly, and even risky.
In this post, we’ll walk through 10 of the most common mistakes companies make when setting up their cloud architecture. These mistakes often lead to security vulnerabilities, unexpected costs, and performance issues. To help businesses avoid these pitfalls, this blog will explore some of the most common mistakes in cloud computing, backed by data points and real-world examples from major companies. We will also discuss how cloud platforms like Google Cloud, AWS, and others provide tools to help mitigate these issues.
Let’s get started!
1. Neglecting Proper Security Practices
One of the biggest mistakes in cloud computing is failing to implement proper security measures. Cloud environments are often seen as secure because providers like AWS, Google Cloud, and Microsoft Azure invest heavily in security.
However, security in the cloud is a shared responsibility. Many businesses fail to properly configure their cloud environment or overlook essential security controls like Identity and Access Management (IAM), encryption, and logging. This oversight can lead to data breaches, unauthorized access, and other vulnerabilities.
Based on the research data ,
- 80% of companies have experienced cloud security incidents in the last year. [ Edgedelta]
- There was a 75% increase in total cloud environment intrusions from 2022 to 2023. [Crowdstrike]
Famous example In 2020, Capital One, a major American bank, suffered a massive data breach due to a misconfigured AWS server. The breach exposed sensitive data of over 100 million customers, and it was later revealed that the root cause was a vulnerability in the company’s AWS configuration. The breach cost Capital One $80 million in fines, not including the reputational damage. If interested to know more on this incident you can read this article
How to Avoid:
- Use IAM policies to enforce the principle of least privilege, ensuring users only have access to the resources they need.
- Enable multi-factor authentication (MFA) for all users, especially for administrative access.
- Regularly audit your cloud environment using tools like AWS Config or Google Cloud Security Command Center to detect misconfigurations.
- Encrypt data both at rest and in transit using platform tools like AWS KMS or Google Cloud KMS.

2. Overprovisioning or Underprovisioning Resources
Many businesses either overprovision or underprovision their cloud resources. Overprovisioning leads to unnecessary costs, while underprovisioning can affect performance and scalability.
Cloud services are often billed on a pay-as-you-go model, which gives businesses the flexibility to scale resources up or down based on demand. However, many businesses either overprovision (allocating more resources than needed, leading to higher costs) or underprovision (leading to performance bottlenecks and service downtime).
Research Data:
According to a 2019 Flexera report, 35% of cloud clou cost wastes because of overprovisioned resources, resulting in wasted cloud spend, while another 30% reported issues with underprovisioning, leading to poor performance.

How to Avoid:
- Use auto-scaling features in platforms like AWS and Google Cloud to automatically scale resources up or down based on demand.
- Use cost management tools like AWS Cost Explorer or Google Cloud Cost Management to track resource utilization and forecast costs.
- Regularly monitor usage with tools like AWS CloudWatch or Google Cloud Monitoring to fine-tune resource allocation and optimize costs.
3. Lack of Backup and Disaster Recovery Planning
Cloud environments can be highly reliable, but data loss can still occur due to human error, software bugs, or security breaches. Failing to have a backup or disaster recovery plan in place can leave you vulnerable.
Businesses that don’t implement backup and disaster recovery plans risk losing critical data, which can result in significant downtime and operational losses.
In 2016, Delta Airlines suffered a major outage due to a power failure that affected its data center, leading to 3,000 canceled flights. The issue was exacerbated by the airline’s failure to maintain an effective disaster recovery plan in the cloud, which resulted in $150 million in lost revenue.
How to Avoid:
- Implement multi-region backups in platforms like AWS S3 or Google Cloud Storage to protect against data loss from regional outages.
- Set up automatic backup schedules for all critical data and test the recovery process regularly.
- Consider disaster recovery-as-a-service solutions like Google Cloud’s Disaster Recovery or AWS Elastic Disaster Recovery for automated recovery.
4. Ignoring Cloud Costs
Cloud services often follow a pay-as-you-go pricing model, which can be very cost-effective when used efficiently. However, it’s easy to overlook resources that are running idle or to ignore unused services, leading to unnecessary costs.y integrating financial accountability into the cloud management process, FinOps enables teams to track and manage cloud usage costs in real-time, creating visibility and accountability across departments.
As per research , 55% of companies are spending more year over year on cloud in 2023.
How to Avoid:
- Leverage cloud cost management tools like AWS Trusted Advisor, Google Cloud’s Cost Management, or Azure Cost Management to track and optimize spending.
- Implement resource tagging to categorize and allocate costs to specific departments or projects.
- Set up usage alerts to receive notifications when usage exceeds predefined thresholds, helping to prevent overspending.
5. Lack of Proper Monitoring and Logging
Cloud environments generate vast amounts of data, and not monitoring or analyzing this data can result in undetected performance issues, security breaches, or errors.
A 2019 Datadog survey revealed that 45% of companies didn’t have a centralized logging system, making it difficult to monitor and troubleshoot performance or security issues in the cloud.
How to Avoid:
- Use cloud-native monitoring services like AWS CloudWatch, Google Cloud Operations Suite, or Azure Monitor to keep track of cloud resources and detect anomalies.
- Implement centralized logging with tools like AWS CloudTrail or Google Cloud Logging to capture and analyze logs in real-time.
- Set up alerts and automated responses to ensure swift action can be taken when issues arise.
6. Failure to Architect for Cloud
Migrating to the cloud is not as simple as lifting and shifting existing infrastructure. Many organizations try to replicate their on-premises environment in the cloud without adjusting for the cloud’s strengths and capabilities.
Common Mistakes When Failing to Architect for the Cloud
- Over-Provisioning Resources: Provisioning without considering cloud scalability can lead to excessive resource use and higher costs.
- Not Leveraging Managed Services: Avoiding cloud-native managed services leads to increased management complexity and missed cost savings.
- Poor Data Storage and Access Choices: Using high-cost storage unnecessarily and neglecting data egress costs can drive up expenses.
- Ignoring Fault Tolerance and Availability Zones: Failing to implement redundancy risks downtime and undermines cloud reliability.
- Not Optimizing for Latency and Performance: Misplacing workloads regionally increases latency; using edge services and proximity improves user experience.
In One of case study I read , Snapchat Early on, Snapchat faced scaling issues on Google Cloud due to architecture that wasn’t cloud-native, leading to high infrastructure costs. They later re-architected for improved performance and cost efficiency, optimizing storage and leveraging managed services.
How to Avoid:
- Redesign applications to be cloud-native, utilizing microservices, containers, and serverless architectures.
- Use managed services like AWS Lambda, Google Cloud Functions, or Azure Functions to reduce operational overhead and increase scalability.
- Leverage cloud load balancing and auto-scaling to ensure seamless handling of variable workloads.
7. Not Planning for Vendor Lock-In
Vendor lock-in is a significant concern when using a single cloud provider. Different cloud providers offer varying services, and migrating to another provider can become difficult and costly.
How to Avoid:
- Choose a multi-cloud or hybrid cloud strategy to avoid relying on one provider.
- Use containerization and orchestration tools like Kubernetes to ensure that applications can run across different cloud platforms.
- Standardize APIs and avoid using proprietary services unless necessary, so that your applications can be moved between cloud providers more easily.
8. Underestimating Compliance and Regulatory Requirements
Cloud environments can be subject to various regulatory and compliance standards, such as GDPR, HIPAA, and SOC 2. Failing to understand these requirements and how they apply to your cloud infrastructure can result in fines, legal issues, and reputational damage.
How to Avoid:
- Familiarize yourself with the regulatory requirements specific to your industry and region.
- Use tools and services that help ensure compliance, such as encryption, access control, and audit logging.
- Work with cloud providers that offer compliance certifications and ensure your cloud setup adheres to necessary standards.
9. Not Managing APIs Effectively
APIs are a crucial part of cloud computing, as they allow different services to communicate with one another. However, managing APIs poorly can lead to security risks, performance bottlenecks, and increased complexity.
How to Avoid:
- Use API gateways to centralize the management of APIs and improve security.
- Monitor API usage to detect anomalies or misuse.
- Set strict version control for APIs to ensure backward compatibility and reduce integration issues.
10. Excessive Manual Work
One of the common pitfalls in cloud management is relying heavily on manual processes for configuration, monitoring, and scaling. Manually setting up cloud resources, updating configurations, and handling repetitive tasks introduces a high risk of human error, especially in large, complex environments.
Real-World Example:
Couple of Year back Uber faced a significant cloud security issue due to a human error in its AWS configurations. An employee unintentionally misconfigured access controls, exposing sensitive customer data. The incident highlighted the risks of relying on manual setups and lack of automation in managing cloud configurations.
