Introduction
AWS provides us with many features like Amazon Connect, AWS Fault Injection Simulator etc., tools that help developers in each sense and make running an online business easier for owners. These good-sounding features come at a cost for the organization. Users find it hard to budget their AWS bill and forecast costs and methods to reduce their overall AWS Bill. Which is becoming too heavy for their pockets, and what benefit a service does if it doesn't fit into the customer's pocket.
There felt an obvious need for having an AWS native tool that could provide Users with a closer look at their spending over time. The monthly bill and basic cost breakdown previously provided were just not adequate. So AWS came up with AWS Cost Explorer. A tool that helps users view and analyze their costs and usage.AWS Cost Explorer helps the user understand their costs and forecast their future costs. Using this, the user could manage their costs holistically and optimize their future costs.

AWS Cost Explorer
Monitoring Cost is an essential aspect for developers. AWS Cost Explorer is a tool that comes with an easy-to-use interface that enables users to help visualize and analyze their costs and usage over time. It allows them to explore their usage and costs using the main graph, the Cost Explorer cost and usage reports, or the Cost Explorer RI reports. Users can view data for up to the last 12 months, which helps them forecast how much they're likely to spend for the next 12 months. This helps them in maintaining future costs. They can get recommendations for what Reserved Instances to purchase.

Not only that, AWS Cost Explorer allows users to view their costs and usage using the Cost Explorer user interface too free of charge. Dataset used in AWS Cost Explorer is the same for generating the AWS Cost and Usage Reports and detailed billing reports.
AWS Cost Explorer also provided us with preconfigured views that display at-a-glance information about user cost trends and gives the user a head start on customizing their views that suit their business needs. When we first sign up for Cost Explorer, AWS prepares the data about costs for the current month and the last 12 months, and then it calculates the forecast for the next 12 months.
