Tips for Cutting Costs in AWS

Amazon Web Services (AWS) is the world’s leading cloud service provider. It offers a wide range of services and features that businesses can leverage to maximize their cloud cost savings. Here are some tips for cutting costs in AWS.

Use Reserved Instances

Reserved instances allow you to reserve capacity for specific services over a set period, typically 1 or 3 years. By committing to a longer-term contract, AWS offers significant discounts compared to on-demand pricing. Therefore, if you have predictable workloads and can forecast your usage accurately, using reserved instances can lead to significant savings.

Leverage EC2 Spot Instances

EC2 spot instances are unused EC2 instances that AWS sells at a discount. They offer the same features as on-demand instances but at a fraction of the cost. However, these instances can be interrupted by AWS with little notice. Therefore, they are best suited for workloads that are not time-sensitive or can withstand interruptions.

Optimize EBS Volumes

Elastic Block Store (EBS) volumes are a type of storage that you can attach to your EC2 instances. By optimizing your EBS volumes, you can ensure that you are not paying for storage that you are not using. This involves selecting the right type of EBS volume for your needs and regularly monitoring your usage.

Using AWS FSx

AWS FSx is a fully managed service that provides cost-optimized file storage for Windows servers and Lustre workloads. By leveraging AWS FSx, you can reduce the costs associated with managing your own file servers and storage infrastructure. Note that an alternative service you can consider if you don’t need high-performance access to storage is Amazon EFS.

Use AWS Cost Explorer

AWS Cost Explorer is a tool that allows you to visualize and manage your AWS costs. It provides detailed insights into your spending patterns, which can help you identify areas where you can cut costs. By using AWS Cost Explorer, you can keep track of your costs and make informed decisions about your cloud spending.

Tips for Cutting Costs in Azure

Microsoft’s Azure is another leading cloud service provider. Here are some strategies to help you navigate Azure pricing and achieve significant cloud cost savings.

Leverage Azure Hybrid Benefit

Azure Hybrid Benefit is a licensing benefit that can significantly reduce your Azure costs. With this benefit, you can use your existing on-premises Windows Server and SQL Server licenses with Software Assurance to pay a reduced rate on Azure.

Azure Hybrid Benefit can save you up to 40% on Windows Server virtual machines and up to 55% on SQL Server. To leverage this benefit, make sure to select ‘Yes’ under Azure Hybrid Benefit when creating a new virtual machine. Remember, the more licenses you bring, the more you save.

Using Azure Cost Management Tools

Azure Cost Management tools provide detailed insights into your cloud spending. They enable you to visualize, manage, and optimize your Azure costs, helping you identify unnecessary expenditures and potential savings.

Azure Cost Management and Billing is a free tool that provides comprehensive cost analysis and advanced cost optimization features. It allows you to track resource usage, manage budgets, and optimize spending across multiple subscriptions.

Cost Management Power BI App is another powerful tool that provides a detailed analysis of your Azure costs. It allows you to create custom reports and dashboards, making it easier to understand and control your cloud spending.

Use Azure VMs

Azure Spot VMs offer a cost-effective way to utilize Azure’s spare capacity. They are available at a significantly lower price than regular instances, allowing you to achieve considerable cloud cost savings.

However, keep in mind that spot VMs are not guaranteed to be available at all times. They are ideal for workloads that can withstand interruptions, such as batch processing, testing, and development.

Optimize Virtual Machine Sizes

Choosing the right virtual machine size is crucial for cost optimization in Azure. Oversized virtual machines result in unnecessary costs, while undersized virtual machines can impact performance.

Azure provides a wide range of virtual machine sizes to choose from. Make sure to select a size that best fits your workload requirements. Regularly review and adjust the size of your virtual machines to ensure optimal performance and cost-efficiency.

Use Azure DevTest Labs
