However, raw data is not always ready for analysis. It may come from different systems and exist in different formats. Data engineers create processes that collect, clean, transform, and organize this information.

Reliable data pipelines ensure that analysts, data scientists, and business applications can access accurate and timely information.

Data Ingestion

Data ingestion is the process of collecting data from different sources and moving it into a suitable storage or processing environment.

Data can originate from applications, databases, APIs, websites, business systems, IoT devices, and log files. Some workloads involve continuous real-time data, while others use scheduled batch processing.

AWS provides multiple services that can support different ingestion requirements. Professionals need to select appropriate technologies based on data volume, frequency, latency, and processing requirements.

Understanding the difference between batch and streaming data processing is an important part of data engineering.

Amazon S3 for Data Storage

Amazon S3 is an important storage service for many AWS data architectures. It provides scalable object storage that can be used to store datasets, files, logs, backups, and other information.

Data engineers can organize information in S3 and use it as part of data lakes and analytics workflows.

Storage design should consider data formats, lifecycle requirements, access patterns, security, durability, and cost. Appropriate organization and metadata can make data easier to discover and process.
