Introduction to AWS

AWS, or Amazon Web Services, offers businesses and people on-demand access to the cloud. It is an Amazon company that offers a range of Infrastructure, Hardware, and Distributed Computing resources. Support for AWS includes enterprise-level storage and compute capabilities as well as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

For enterprises, cost-saving choices include AWS and other cloud computing services like Microsoft Azure, Google Cloud, and Alibaba Cloud. While on-premise storage and computing need sophisticated configurations and are not a cost-effective option, most Cloud Platforms charge on a pay-per-use basis.

Networking, monitoring tools, database storage, data warehouse, cloud computing, data analytics, security, etc. are among the services offered by Amazon Web Services. There are AWS Data Centers located across the world in various areas. Depending on how close its end customers are, a business can select from a variety of Availability Zones for AWS services. In order to prevent data loss in the event that one Data Center fails, it also replicates data across additional Data Centers.

Virtual Machines (VMs) are used by Amazon Web Services to operate a variety of applications, including websites, online video streaming, online gaming, etc. Additionally, it offers an Auto-Scaling capability that enables customers to change the storage and computational capacity according on their needs.

Introduction to AWS Data Engineering

Data Volume has dramatically expanded as a result of the expansion of many platforms, services, and device kinds. To execute analytics on their data, enterprises require a storage pool that is efficient and enough computer power. A lot of providers, such AWS, Google Cloud, and Microsoft Azure, offer infrastructures that are ready to use. Big Data and Data Analytics-trained engineers oversee all services, do optimization, and fulfill customer demands. First, let's define what data engineering is.

Analyzing customer needs and creating software that focuses on storing, transferring, converting, and organising data for Analytics and Reporting purposes is known as data engineering.

AWS Data Engineering focuses on overseeing several AWS services so that clients may receive an integrated solution that meets their needs. An AWS Engineer examines the customer's requirements, their data's quantity and quality, and the outcomes of their activities. In order for consumers to utilize them and perform at their best, they also choose the greatest equipment and services.

Data Pipelines are used to handle the extraction of data from many sources and storage in the Storage Pool (Data Lake, Data Warehouse). AWS Data Engineering also makes ensuring that customers have access to data in a form that is suitable for analysis.

AWS Data Engineering Tools

AWS Data Engineering employs a variety of procedures and technologies that were all created by AWS to meet certain needs. This section will teach you how to use the AWS Data Engineering Tools and the steps used to get a certain outcome. Although AWS offers a wide variety of tools, this section focuses on those that AWS Data Engineers utilize the most. Among them are:

  • Data Ingestion Tools
  • Data Storage Tools
  • Data Integration Tools 
  • Data Warehouse Tools
  • Data Visualization Tools

Data Ingestion Tools

Data ingestion tools collect several kinds of unstructured data from a variety of sources, including mobile devices, sensors, databases, APIs, and real-time data streams and streams of text. To store in a Storage Pool, this heterogeneous data must be gathered from many sources. In order to get data from all sources, AWS offers a variety of data ingestion tools. The AWS Data Engineering task that takes the longest to complete is the data ingestion procedure.

  • Amazon Kinesis Firehose
  • AWS Snowball
  • AWS Storage Gateway

Amazon Kinesis Firehose

Amazon S3 receives fully controlled real-time streaming data using Kinesis Firehose. Prior to being stored in Amazon S3, data can also be transformed using Kinesis Firehose. Encryption, compression, Lambda functions, and data batching capabilities are supported by Kinesis Firehose.

It is automatically scalable and is based on the yield and volume of the incoming streaming data. Before importing data into Amazon S3, Lambda Functions can change it from the source to the required structure. Kinesis Firehose is used by AWS Data Engineering to provide smooth data transfer after encryption.

AWS Snowball

The best tool for transferring company data from local databases to Amazon S3 is called Snowball. AWS employs a Snowball device to ship to the location of the data source and links it to the Local Network in order to solve the issue of duplicating data from on-site data sources to Cloud Storage.

Data from nearby computers can be sent to the Snowball device. Furthermore, AES-256-bit encryption is supported. Businesses may return the device to AWS and move the data to Amazon S3.

AWS Storage Gateway

Many businesses have operational equipment on-site that are necessary for everyday operations, but they could require routine data backup on Amazon S3. Fortunately, AWS Data Engineering offers a Storage Gateway that enables businesses to use the File Gateway configuration of Storage Gateway to transport data from local data sources to Amazon S3. To communicate data with Amazon S3, a network file system connection is used.

Using the Distributed File System Protocol (NFS), you may send files to Amazon S3 over the network. File-sharing between Amazon S3 and on-premises workstations may be started by configuring the file-sharing settings in the AWS Storage Gateway Console.

Data Storage Tools

All of the data is stored in data lakes or storage pools after the data extraction procedure. AWS offers a variety of storage options depending on the need and mechanism of data transfer. AWS Data Engineering expertise is necessary to choose the most appropriate Data Storage service for a given activity.

Users need data storage tools to supply High Power Computation (HPC) solutions. Depending on the needs, Amazon Web Services offers several storage solutions. These data storage options are reasonably priced and simple to integrate with other processing software. It may gather information from several sources and change it into a particular Schema.

Amazon S3

Amazon Simple Storage Service is referred to as Amazon S3. A data lake that can store any volume of data from anywhere on the internet is called Amazon S3. Because it is an incredibly scalable, quick, and affordable option, Amazon S3 is frequently utilized in AWS Data Engineering for data storage from numerous sources. Data is kept in S3 as Objects, which are basic units made up of data and their metadata. Pairs of objects are stored, and the metadata in each pair—for example, Date includes a Date-Time description—describes the corresponding data.

A cost-effective data storage option that doesn't require any upfront hardware expenses is Amazon S3. You are also allowed to duplicate your S3 storage across different Availability Zones. For effective data backup and restore functionality, you may configure recovery point objectives and recovery time objectives.

Web-based cloud apps with flexible settings that scale automatically may be operated effectively. You may use Amazon S3 to execute Big Data Analytics with AWS Data Engineering for improved insights.

Data Integration Tools

Data Integration Tools use the ETL (Extract Transform Load) or ELT method to merge data from several sources into a consolidated perspective (Extract Load Transform). Data Integration includes the procedure carried out with the aid of Data Ingestion Tools. Due to the necessity for examination of many sources' Schemas and the time required to transport data, AWS Data Engineering considers data integration to be the most time-consuming activity.

AWS Glue

AWS Glue is a serverless Data Integration Service that aids in the Data Ingestion process of gathering data from many sources. Prior to loading the data into a data lake or data warehouse, it is also in charge of performing the data transformation to the appropriate schema.

It was previously noted that Data Lakes are Storage Pools that may store data in its original form, hence doing Data Transformation while loading data is optional. But in order to do quick queries, analytics, and reporting, data warehouses need a consistent schema.

AWS Data Engineering makes use of AWS Glue's strength to offer all operations, from data extraction to standard Schema transformation. It oversees the Data Catalog, which serves as a central database for metadata. Tasks may be completed with AWS Glue in weeks as opposed to months.

Data Warehouse Tools

A data warehouse is a location where organized, filtered data from various sources is kept. What distinguishes it from data lakes like Amazon S3, though, since it likewise stores data from several sources?

Data lakes gather unprocessed data from many sources in its native or altered forms. Data Warehouses store data with a clear purpose in a standard Schema for query optimization while Data Lakes store data with no purpose identified as of yet.

Amazon Redshift

The best data warehouse option is Amazon Redshift, which offers petabytes of structured or semi-structured data storage. In order to execute Data Analytics on a sizable volume of data and feed data to various Business Intelligence Tools, Dashboards, and other applications, AWS Data Engineering provides quick querying. Because of this, Amazon Redshift uses a standard Schema for all data.

Following the Data Transformation procedure, Amazon Redshift loads data from Amazon S3 with the aid of AWS Glue. Exabytes of data may be processed using Amazon Redshift's massively parallel processing (MPP), which offers enormous computing capability.

Data Analysts and Data Scientists can perform queries from Amazon S3 using Amazon Redshift Spectrum thanks to AWS Data Engineering. Moving data from S3 to Amazon Redshift takes less time. However, if this procedure is needed a few times, it is practical. If data needs frequent, quick querying for Analytics and Reporting, it is preferable to migrate it from Amazon S3 to Amazon Redshift.

Data Visualization Tools

Data Visualization is the final phase in AWS Data Engineering. An AWS Data Engineer works for this primary purpose. The Data Visualization Tools are a collection of business intelligence (BI) techniques that use AI, ML, and other tools to study data.

The tools that produce reports, graphics, and insights from data use all the data from the Data Warehouse and Data Lakes as inputs. Advanced business intelligence (BI) solutions with machine learning capabilities enable users discover correlations, compositions, and distributions in data and get deeper insights from it.

Amazon QuickSight

The finest tool on Amazon for creating BI Dashboards quickly and simply is called Amazon QuickSight. It has the ability to provide machine learning insights. You may access Amazon QuickSight using a web browser, a mobile device, or by embedding the QuickSight dashboard in various applications, websites, and portals. The integration of Amazon Redshift with other business intelligence and business analytics products is another area of concentration for AWS Data Engineering.
