Every unnecessary cent spent brings your organization one step closer to the end of it’s runway, a grueling fundraising round, or even the end of your startup.
As a founder, you want to focus on innovation and finding that perfect product-market fit, not worrying about infrastructure or unexpected costs. According to RightScale, small and medium-sized companies overspend by an average of 35% on cloud resources. This equates to $6.4 billion in annualized wasted cost for AWS alone.
One way many startups manage costs is by opting to use flexible AWS cloud infrastructure. With this in mind, Here is a how-to guide to help you create a cost-effective AWS environment for your small startup.
Why Should Startups Use AWS?
Before diving into specific cost-saving tips, let’s explore why startups should consider using a cloud infrastructure provider like AWS. Physical infrastructure can quickly consume a large portion of a startup’s budget.
Cloud infrastructure, particularly when provided by AWS, offers a flexible solution to this problem. It can scale up or down based on demand, allowing startups to avoid the significant expenses of maintaining physical infrastructure. Additionally, AWS outsources much of the technical work to a highly specialized team that excels in maximizing efficiency and passing those savings on to their clients.
That said, cloud infrastructure isn’t automatically cheap. Poor optimization can lead to escalating costs. That’s why AWS emphasizes cost optimization as a core aspect of their Shared Responsibility Model and Well-Architected Framework. While it’s the responsibility of AWS customers to configure their infrastructure properly, AWS provides several built-in optimization tools and partners who can assist in ensuring cost-effective usage.
Getting Familiar with the AWS Environment.
Start by getting comfortable with the AWS Management Console. This is your primary interface for managing AWS services.

Setting Up Basic IAM (Identity and Access Management)
Properly managing user access is crucial for both security and cost management.
Create an IAM User with Administrator Privileges:
Log into your root account and start by creating a dedicated IAM user with admin privileges, not using your root account enhances security by limiting access to sensitive functions.
Step-by-Step Instructions to create an IAM user with Administrator Privileges*:
Step 1: Go to the IAM dashboard.
Step 2: Click on Users
Step 3: Click on Create user.
Step 4: Add User name
Step 5: Assign the user to the AdministratorAccess policy.
Step 6: Review and Create and click on Create User
You should see User Successfully Created at the top of your screen.
Set Up an IAM Group for General Users:
Create an IAM group for your team with appropriate access policies. For example, developers might need full access to EC2 but only read-only access to billing information.
Step-by-Step Instructions to set up an IAM group:
Step 1: In the IAM dashboard, go to Groups
Step 2: Click on Create Group
Step 3: Give your Group a name.
Step 4: Next, add users to the group
Step 5: Attach relevant policies
Step 6: Click on Create user group
Now you have your group.
Assign Basic Policies and Permissions:
Start with managed policies such as ReadOnlyAccess or PowerUserAccess. This limits exposure to potential errors and keeps your AWS environment secure.
Assigning Basic Policies and Permissions in IAM
When setting up IAM users in AWS, assigning the right policies and permissions is crucial for managing access and ensuring security. Policies define what actions a user can perform on AWS resources, and understanding how to assign them effectively can prevent unauthorized access and minimize security risks.
Understanding Basic PoliciesAWS Identity and Access Management (IAM) policies are JSON documents that define what actions are allowed or denied for specific AWS resources.
There are two main types of policies you might work with:
Managed Policies: These are pre-defined by AWS and are a good starting point for common use cases. AWS provides a variety of managed policies for different services and tasks, such as AmazonS3ReadOnlyAccess or AmazonEC2FullAccess.
Inline Policies: These are custom policies attached directly to a specific IAM user, group, or role. Inline policies offer fine-grained control and are useful when you need to tailor permissions for specific needs. However, they can become cumbersome to manage as your environment grows.
Assigning Policies to IAM Users
Follow these steps to attach managed policies to your IAM users.
Step 1: Select Users from the IAM dashboard
Step 2: Click on the User you want to assign permissions.
Step 3: Click on the Permissions tab
Step 4: click on Add permissions.
Step 5: Choose Attach policies directly
Step 6: Select from the list of managed policies.
Step 7: Scroll down and click on Next
Step 8: Review the policies and click Add permissions.
2.Create and Attach Inline Policies:
Step-by-step instructions on how to create and attach inline policies:
Step 1: From the IAM dashboard, select the User you want.
Step 2: Go to the Permissions tab.
Step 3: Click Create inline policy
Step 4: Use the Visual editor or JSON editor to define the policy.
Step 5: Click on Visual for this guide
Step 6: Select service and click on s3 (like s3:GetObject)
Step 7: Type GetObject in Actions allowed and select actions from the service to be allowed.
Step 8: Choose ANY in the resources section to grant permissions to any resources of that type.
Step 9: Click Next
Step 10: Give your policy a name
Step 11: Review the policy and click Create policy to attach it to the selected user.
Best Practices for Policy Assignment
Follow the Principle of Least Privilege: Only grant the permissions necessary for a user to perform their job. Avoid using overly permissive policies, which can lead to security vulnerabilities.
Use Groups for Common Permissions: Assign users to groups with predefined policies to manage permissions more efficiently. This is especially useful for larger teams where multiple users need the same access.
Regularly Review and Adjust Permissions: Periodically review IAM policies and permissions to ensure they are still appropriate. As your team or projects evolve, adjust permissions to match current needs.
By carefully assigning basic policies and permissions, you ensure that your AWS environment remains secure and that users have the appropriate level of access to perform their tasks effectively.
Leveraging AWS Pricing Models
Understanding AWS pricing models helps you avoid unnecessary costs:
On-Demand Pricing: Ideal for short-term, unpredictable workloads. You only pay for what you use without any long-term commitments.
Reserved Instances and Savings Plans: If you have predictable workloads, consider these options to save up to 72% over on-demand pricing.
Spot Instances: Use these for flexible workloads to take advantage of up to 90% discounts. Great for batch processing or data analysis tasks that can be interrupted.
Cost Optimization Tools
AWS provides several tools to help you monitor and control spending:
AWS Cost Explorer: Use this tool to analyze spending patterns, set up forecasts, and identify cost-saving opportunities.
AWS Budgets: Set custom budgets to track costs and receive alerts when spending exceeds thresholds.
AWS Trusted Advisor: Leverage this tool to get personalized recommendations for cost optimization, security improvements, and performance enhancement.
Implementing Advanced Cost Management Strategies
To keep costs under control, apply these strategies:
Use Resource Tagging: Tag your resources to track spending by project or department. This makes it easier to identify cost drivers.
Right-Size Your Resources: Regularly review and adjust your instances, storage, and other resources to match your current needs.
Optimize Data Transfer: Minimize costs associated with data transfer by using services like Amazon CloudFront for content delivery.
Monitoring and Automation.
Continuous monitoring and automation help keep your environment cost-efficient:
Use AWS CloudWatch: Set up alarms and dashboards to monitor usage, performance, and costs in real-time.
Automate with AWS CloudFormation: Use Infrastructure as Code (IaC) to automate deployments, reducing manual errors and streamlining operations.
Securing Your AWS Environment.
Security is vital when setting up a cloud environment:
Implement IAM Best Practices: Use multi-factor authentication (MFA), apply the principle of least privilege, and regularly audit permissions.
Enable AWS Security Tools: Use services like AWS Shield for DDoS protection and AWS Config for compliance checks.
Conclusion
By setting up a cost-effective AWS environment, managing user access with IAM, leveraging cost optimization tools, and selecting the right services, you can ensure your startup makes the most out of AWS without overspending.
