** AWS S3 Simple Storage Service **
Object storage built to store and retrieve any amount of data from anywhere. Amazon Simple Storage Service (Amazon S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance. You can use Amazon S3 to store and retrieve any amount of data at any time, from anywhere.

** IAM User **
An AWS Identity and Access Management (IAM) user is an entity that you create in AWS. The IAM user represents the human user or workload who uses the IAM user to interact with AWS. A user in AWS consists of a name and credentials.

** IAM User Policy **
Policy is to manage access in AWS by creating policies and attaching them to IAM identities (users, groups of users, or roles) or AWS resources. A policy is an object in AWS that, when associated with an identity or resource, defines their permissions.

** Java AWS SDK **
AWS SDK for Java simplifies use of AWS Services by providing a set of libraries that are consistent and familiar for Java developers. It provides support for API lifecycle consideration such as credential management, retries, data marshaling, and serialization. The AWS SDK for Java also supports higher level abstractions for simplified development.

** Maven Application Building Tool **
Apache Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central piece of information.
