AWS Redshift is a serverless cloud-based data warehouse provided by Amazon as a part of Amazon Web Services. It is a fully managed and cost-effective data warehouse solution. AWS Redshift is designed to store petabytes of data and can perform real-time analysis to generate insights.

AWS Redshift is a column-oriented database, and stores the data in a columnar format as compared to traditional databases that store in a row format. Amazon Redshift has its own compute engine to perform computing and generate critical insights. 

To know more about AWS Redshift, follow the official documentation here.

What is Redshift Architecture?

AWS Redshift has straightforward Architecture. It contains a leader node and cluster of compute nodes that perform analytics on data. Below snap depicts the schematics of AWS Redshift architecture:

AWS Redshift offers JDBC connectors to interact with client applications using major programming languages like Python, Scala, Java, Ruby, etc.

What is ETL?

ETL is an abbreviation for Extract, Transform, and Loading. With the introduction of cloud technologies, many organizations are trying to perform ETL to migrate their data. They often have data storage as an RDBMS or legacy system which lacks performance, scalability, and fault-tolerant systems. Hence, to get better performance, scalability, and fault-tolerant systems, organizations are migrating to cloud technologies like Redshift.

In a typical industrial ETL scenario, data is first extracted from legacy sources by using connectors. Then it is transformed by applying calculations like filter, aggregation, ranking, business transformation, etc., to derive outcomes, and then it is loaded onto the target systems. The below schematics will give a better understanding of ETL flow.

Scale your data integration effortlessly with Hevo’s Fault-Tolerant No Code Data Pipeline

As the ability of businesses to collect data explodes, data teams have a crucial role to play in fueling data-driven decisions. Yet, they struggle to consolidate the data scattered across sources into their warehouse to build a single source of truth. Broken pipelines, data quality issues, bugs and errors, and lack of control and visibility over the data flow make data integration a nightmare.

1000+ data teams rely on Hevo’s Data Pipeline Platform to integrate data from over 150+ sources in a matter of minutes. Billions of data events from sources as varied as SaaS apps, Databases, File Storage and Streaming sources can be replicated in near real-time with Hevo’s fault-tolerant architecture.

What’s more – Hevo puts complete control in the hands of data teams with intuitive dashboards for pipeline monitoring, auto-schema management, and custom ingestion/loading schedules.

AWS Glue is a fully managed and cost-effective serverless ETL (Extract, Transform, and Load) service on the cloud. It allows you to categorize your data, clean and enrich it, and move it from source systems to target systems. 

AWS Glue uses a centralized metadata repository known as Glue Catalog, to generate the Scala or Python code to perform ETL and allows you to modify and add new transformations. It also does job monitoring, scheduling, metadata management, and retries.

Key Features of AWS Glue

  1. AWS Glue is a cloud-based ETL tool that uses Python as its base language for generating ETL codes.
  2. It offers several useful pre-built transformations that can be plugged into existing ETL logic, and you can also create custom functions to integrate into the flow.
  3. AWS glue is mostly used for batch data, but in combination with other offerings of AWS like Lambda or Step, a near-real-time scenario can be achieved.
  4. You can use AWS Glue to perform effective ETL on the data without having to think about performance, scalability, and other parameters. 

AWS Glue Price

AWS Glue has a pay-as-you-go pricing model. It charges an hourly rate, billed by the second. Check about AWS Glue pricing here.

AWS Kinesis

Amazon Kinesis is a serverless Data Analytics service and is the best tool to analyze real-time data. With the use of pre-built templates and built-in operators, you can quickly build sophisticated real-time applications.

AWS Data Pipeline is a serverless web service that you can use to automate data extraction and Transformation by creating a data-driven workflow that will contain dependent tasks.

AWS Data Pipeline is different from AWS Glue as it allows more control on the job, and you can stitch the various AWS services into one to create an end-to-end pipeline.

Key Features of AWS Data Pipeline

  1. AWS Data Pipeline is an orchestration tool that creates data-driven workflows by combining various services/states of AWS.
  1. It allows you to choose from various AWS services and build custom pipelines and then scheduling the jobs.
  1. You can select EC2 Clusters for computation, S3 for storage, Lambda for event-based triggers, and then combine them to a single dependent workflow in AWS Data Pipeline.
  1. It allows you to run the job using MapReduce, Hive, Pig, Spark, or Spark SQL.

AWS Data Pipeline Pricing

AWS Data Pipeline has a pay-per-use model, and you have to pay for your pipeline based on how often your activities and preconditions are scheduled to run and where they run. For more information, see AWS Data Pipeline Pricing.
