A cloud native app is a software application that is designed specifically to run on cloud computing infrastructure, using containers, microservices, and service-oriented architecture (SOA) principles. Cloud native applications are designed to be scalable, resilient, and portable, with built-in automation and management tools to enable rapid deployment and scaling in cloud environments.

Custom Software Development refers to the process of designing, developing, and deploying software applications tailored to meet specific business needs. It involves creating software that is designed to address the unique requirements of a particular organization, rather than using off-the-shelf software that may not fully meet the organization's needs.

Software architecture is concerned with making key design decisions, such as selecting the appropriate software components, defining the data models and interfaces, and specifying the communication protocols and interaction patterns between the components. It also includes identifying and managing trade-offs, such as balancing performance, scalability, security, and maintainability requirements.

Robotic Process Automation (RPA) is a technology that uses software robots to automate routine and repetitive business processes. It can help organizations to reduce costs, improve efficiency, and free up human employees to focus on more complex and strategic tasks. RPA uses artificial intelligence (AI) and machine learning (ML) technologies to automate tasks and processes that are typically performed by humans.
