What is Amazon Redshift?

Before you decide if Amazon Redshift suits your data requirements, it is crucial to comprehend what it does. An knowledge of the advantages and disadvantages for Amazon Redshift will help you make a well-informed choice.

What exactly is Amazon Redshift?

Amazon Web Services (AWS) is the very first public cloud service provider that offers a cloud-baseddata warehouse that is petabyte-sized service. The service is referred to as Amazon Redshift and is the most well-known cloud-based data warehouse.

Amazon boasts thousands of companies as customers. However, competition in this area is increasing and there are Google Big Query, Snowflake as well as Oracle Automation Data Warehouse eyeing some of the lucrative cloud market for data warehouses.

Amazon Redshift has been around since 2013 and has gone through numerous improvements. Amazon Redshift Spectrum, AWS Athena and the ever-present massively scalable data storage service, Amazon S3, compliment Amazon Redshift and offer all the tools needed to build an data warehouse or data lake that is enterprise-scale. Let’s dig a bit deeper to discover the advantages and disadvantages for Amazon Redshift in more detail.

Amazon Redshift’s advantages Amazon Redshift

Widely accepted

Amazon Redshift has a thriving and loyal customer base. It is it is among the first cloud-based data warehouse technologies. A thriving ecosystem of expert resources are available to help businesses in the process of generating benefits from their data warehousing initiatives.

Administration is easy

Amazon Redshift offers an assortment of tools that can help reduce the administrative burden that is typically incurred when managing the database. The tools are available to build clusters quickly and automate backups of the database up, allowing you to expand the data warehouse both up and down. All of these tasks required database administrators previously. With the tools specifically made available by Amazon Redshift, users can press a few buttons or use REST APIs to complete these tasks.

Ideal for data lakes

Amazon Redshift Spectrum extends the capabilities that Redshift has by permitting it to increase the capacity of storage and compute independently of one another and makes queries on the data within S3 buckets.

It is easy to ask questions

Amazon Redshift has a similar querying language that is similar to PostgreSQL. Anyone who is familiar with PostgreSQL can utilize their SQL expertise to get started using Redshift Clusters. JDBC as well as ODBC support lets developers join their Redshift clusters by using an DB query tool of their choice. Redshift console also permits users to make queries and access the database. However, those who are power users may prefer using a different application of their preference. Many business intelligence software on the market today are compatible with Amazon Redshift.

Columnar storage

When rows are entered into the database of a relational type it is usually in a row-format. Although row formats are efficient when writing but they do not perform as well when it comes to reading. Columnar compression utilizes redundant data in every row and a column-oriented compression technique can compress the missing data in fields more effectively. By compressing the column data the size of the disk will be greatly decreased. A query that is based on columns can be able to scan with a smaller footprint of data and transmit a lesser amount of data through the network or the I/O subsystem to the compute Node to process. This results in a substantial increase in the efficiency of the analytical query processing.

Amazon Redshift is an MPP database. MPP is a shorthand in the acronym Massively Parallel Processing. A streamlined application of storage algorithm columnar as well as methods for data partitioning provide Amazon Redshift an edge in terms of performance.


The capacity to scale is among the most crucial features of a database, which is why Amazon Redshift is no different. Scaling the Redshift cluster is easy as compared to scaling an on-premises database. The internal issues involving hardware expansion, VM resizing, and data rebalancing between the nodes are managed entirely through Amazon Redshift and hidden under the gui of a UI button or HTTP API.


Security is an important obstacle for many businesses’ use of cloud-based services. It is important to understand that cloud services provide the highest level of security when they are properly set up in comparison to internally-designed IT (Information Technology) teams Security configurations. The size of cloud services lets them hire greater resources and to deploy cloud services to secure and monitor the cloud’s environment 24x7x365.

Amazon Webservices is no different. When we speak of Amazon Redshift security, it is not possible to do it by itself. The security features offered via Amazon Redshift are available to customers on top of the security features implemented at the cloud service layer. Access management and identity protection that is robust as well as role-based access control (RBAC) and encryption during transit and in rest, as well as SSL connections are a few security features available on Redshift.

AWS ecosystem is strong AWS ecosystem

If you’re considering Amazon Redshift as your data warehouse, you’ve got certain environments that are already operating on AWS. While it is important to select the right applications for your workloads is, it’s important to consider other elements such as community support as well as pricing and discounting and the skills of your company.

A decision to choose a specific technology has both tactical and strategic implications. It might not be a concern for smaller companies. However, larger companies with established teams should take these elements into consideration when selecting any software for example, selecting an AWS data warehouse. With the wide range of services available through AWS businesses can gain by bundling their offerings to reap the benefits of the products and services that are used.


Numerous factors affect the cost of purchasing the Amazon Redshift cluster. Anyone who is considering Amazon Redshift as their data warehouse needs to understand these elements thoroughly to avoid unanticipated surprises.

The cons of Amazon Redshift

Amazon Redshift is a data warehouse system designed for. The entire system is tuned and optimized for an exact workload, which is analytics processing. If you’re looking for databases that can perform efficient transaction processing. In this scenario, AWS has several other options like Amazon Aurora, Amazon RDS, DynamoDB, and others that you could think about.

It is not a multi-cloud solution.

The ecosystem plays an important part in determining the selection of software, the absence of choices is seen as a way for the software company to keep customers into their services. Amazon Redshift, unlike Snowflake it is available only through AWS. If you’re a client from Azure, GCP, or Oracle Cloud be sure to look at the solutions offered by these cloud providers before you decide to choose Amazon Redshift.

Amazon Redshift is not 100 percent controlled

Although the tools provided by Amazon can reduce the need to employ a database manager full-time, they do not completely eliminate the need for one. Amazon Redshift is known to be unable to handle storage effectively in an environment that is prone to frequent deletions. Sort order maintenance is essential to achieve efficient performance metrics. The aspects that affect the databases aren’t commonly understood by developers, and many could argue that they need not bother. They would be right.

The present advancements in technology for databases can remove the requirement for users to be aware of these topics of administration for databases and control the database to ensure optimal performance, without the need of an administrator of databases. Snowflake as well as Oracle Autonomous data warehouses have made huge strides in this area. Amazon Redshift has already released several features, including automatic table sorting and automatic vacuum deletes and automatic analysis, showing the progress made on this front.

Concurrent execution

The issue of concurrent execution has become a common problem when working with MPP databases. If there are multiple concurrent users are running the same queries Redshift may encounter issues with performance. Furthermore because of the lack of separating storage and computing the read workload is affected by the powerful writing that is happening in the database as a result of the massive batch processing task.

Resizes of clusters cause disruptions of the service for the user. While it is not a major issue however, the absence of seamless cluster resizes and capabilities, is an issue in a marketplace which has competition offering the capability to scale down and up without interruption. The minor inconvenience is acceptable for the majority of businesses, but it is it is a problem for some.

Key selection can affect the performance and cost

In the cloud performance is the price.

Users must be careful in constructing their strategies for distribution and sort keys , while being aware of the requirements for the future. They must also periodically review the reliability of their key type and distribution keys as more data is introduced into Amazon Redshift. Amazon Redshift data warehouse. An unoptimal design could increase the cost associated with Redshift. Redshift data warehouse due to the fact that performance of the system decreases and this can lead to problems with satisfaction of users. It is simple to increase the size of your cluster to address the issue but it would also increase the cost. However, a well-thought-out method allows businesses to make the most the Amazon Redshift investment before scaling up.

Master Node

The Master Node performs a crucial part for the Redshift architecture, orchestrating queries that involve execution, allocation, and aggregation as well as the execution results. Every client interacts directly with the master, thus, a master node serves as a one-stop point for failure in the system.

It is not a serverless architecture.

Amazon Redshift is an old approach to cloud-based data warehouses. Redshift isn’t without its flaws and was developed many years back. A serverless design allows the manufacturer to perform an increased level of optimization for the hardware, which translate into lower costs for the customers. The cost will be lower when the same equipment is used by three people instead of. one. Old guards benefit due to their presence for a long time , and continuously innovating over a long period. The benefits can outweigh perceived disadvantages, but sometimes they don’t.
