AWS offers low cost, on-demand IT solutions to help you build and launch your applications quickly and easily with minimum costs. With no upfront investments and a pay-as-you-go price model, you only pay for what you use, when you use it, to build your minimum viable product (MVP), experiment and iterate, all at low cost.

Once you start building your product, here are some additional ways you can continue to control your costs and grow your startup with AWS.

Monitor your use of AWS cloud resources with Amazon CloudWatch to get actionable insights and metrics to help you manage your usage in the most cost effective manner. Use Auto Scaling to scale your Amazon EC2 capacity up during demand spikes, or down during demand lulls to minimize costs. Automate your infrastructure and handle peaks in workloads or traffic to further reduce costs, by using Amazon Elastic Beanstalk, an automation tool to deploy and manage applications in the cloud.

Reserved Instances
The Science of Choosing Reserved Instances

Take advantage of our multiple pricing models for our compute services such as Amazon Elastic Compute Cloud (Amazon EC2), a web service that provides resizable compute capacity in the cloud. Depending upon your utilization, either light, medium or heavy, invest in guaranteed reserved capacity and pay a low upfront fee to get a significantly discounted hourly rate. In some cases, depending on your utilization, you can save up to 65% with reserved instances over On-Demand. Save even more (up to 99%) compared to pro-rated AWS pricing by purchasing Reserved Instances listed by 3rd Party sellers. Match your instance type to your workload density to get the performance you need at the right price.

You can save even more with Spot instances which allow you to bid by naming your own price for Amazon EC2. The Amazon EC2 Spot Instance pricing model complements the On-Demand and Reserved Instance pricing models, providing potentially the most cost-effective option for obtaining compute capacity, depending on your application. Spot Instances can significantly lower your computing costs for time-flexible, interruption-tolerant tasks and are often less costly than On-Demand instances. For distributed, fault-tolerant tasks, such as web crawling, you may be able to simultaneously accelerate your computational task and reduce its overall cost by opportunistically incorporating Spot Instances.

Save as you scale up and save more as you use more. With our tiered pricing model for Amazon Simple Storage Service (S3), the more you use our storage and data resources, the less you pay per unit. In addition, volume discounts and custom pricing are available to customers for high volume projects with unique requirements.

As your startup grows, continue to optimize your spend and keep your development costs low by making sure you revisit your architecture often, to adjust to your startup growth. Manage your cost further by leveraging different options such as S3 CloudFront for caching & offloading to reduce cost of EC2 computing, as well as Elastic Load Balancing which prepares you for massive scale, high reliability and uninterrupted growth. Another way to keep costs down is to use AWS Identity and Access Management solutions (IAM) to manage governance of your cost drivers effectively and by the right teams.
