  • by

Before you decide if Amazon Redshift suits your data requirements, it is crucial to comprehend the nature of. A thorough 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 to provide the cloud-based, petabyte-scale storage 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 clients. Yet, competition in the 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 ubiquitous massively scalable data storage service, Amazon S3, compliment Amazon Redshift and offer all the tools needed to build a data warehouse or a data lake at an enterprise scale. Let’s dig a bit deeper to discover the advantages and disadvantages for Amazon Redshift in more detail.

The advantages of Amazon Redshift

Widely accepted

Amazon Redshift has a thriving and a large customer base, being it is among the first cloud-based technology for data warehousing. A thriving ecosystem of expert experts is readily available to assist businesses in the process of generating benefits from their data warehousing initiatives.

Administration ease

Amazon Redshift offers an assortment of tools that can help reduce the administrative burden commonly entailed when managing databases. Tools are provided to easily create clusters and automate backups of the database up to allow you to increase the size of your data warehouse upwards and downwards. These tasks required database administrators previously. With the special tools that are that are available through Amazon Redshift, users can press a few buttons or make use of REST APIs in order to complete these tasks.

Ideal for data lakes

Amazon Redshift Spectrum extends the capacity offered by Redshift, allowing it to expand storage and compute independently of each other. It also makes queries on the data inside S3 buckets.

It is easy to ask questions

Amazon Redshift has a similar querying language as the well-known PostgreSQL. Anyone who is familiar with PostgreSQL can apply their SQL expertise to get started using Redshift Clusters. JDBC along with ODBC support lets developers access their Redshift clusters by using their DB query tool of their choice. Redshift console also permits users to create queries and also work with the database. However, those who are power users may prefer using a different software of their preference. The majority of business intelligence tools on the market today can be paired with Amazon Redshift.

Columnar storage

When rows are entered into the database of a relational type the data is typically saved in a row-format. While row formats are efficient for writing operations however, they are not as efficient when reading. Columnar compression utilizes redundant data for each row and a column-oriented technique can compress the missing data in fields faster. By compressing the column data the footprint of storage on the disk will be greatly diminished. A query that is based using columns will scan with a smaller footprint of data and send a smaller amount of data through the network or the I/O subsystems to the compute node to process. This results in a substantial improvement in the speed 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 techniques for partitioning data can give Amazon Redshift an edge in terms of performance.


Scalability is among the most crucial aspects of a database which is why Amazon Redshift is no different. Scaling the Redshift cluster is a breeze as compared to scaling an on-premises database. Hardware expansion-related issues that arise from internal processes, VM resizing, and shifting data between nodes are managed entirely through SQL Workbench Redshift and hidden under the cover of a UI button or an HTTP API.


Security is a major obstacle for many businesses’ use of cloud-based services. But, it’s important to recognize that cloud services provide an incredibly higher level of security when properly configured in comparison to the internal IT (Information Technology) teams and their security configurations. The size of cloud services lets them hire greater resources and to deploy them to manage and secure the cloud’s environment 24x7x365.

Amazon Webservices is no different. When we speak of Amazon Redshift security, it can’t be done by itself. The security features provided through Amazon Redshift are available to users in addition to the security capabilities implemented by the cloud service layer. Access management and identity protection that is robust and access control based on role (RBAC) and encryption during transit and in rest, as well as SSL connections are a few security options available in Redshift.

AWS ecosystem is strong AWS ecosystem

If you’re thinking of Amazon Redshift as your data warehouse, you’ve got several environments operating on AWS. As crucial as choosing an appropriate application for your workload is, it’s important to consider other factors such as community support as well as pricing and discounting and the skills of your company.

The choice of a particular technology can have both tactical and strategic implications. It’s not a big deal for smaller companies. However, larger companies with established teams should consider these aspects when selecting any software for example, selecting an AWS data warehouse. With the variety of services available through AWS companies can profit 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 in depth to avoid any unanticipated surprises.

Pros and Cons of Amazon Redshift

Amazon Redshift is a data warehouse system designed for. The entire system is tuned and optimized for particular workloads, such as analytics processing. If you’re looking for an efficient database for transaction processing. In this scenario, AWS has several other options like Amazon Aurora, Amazon RDS, DynamoDB, and others which you might want to look into.

There is no multi-cloud option.

The ecosystem plays a crucial part in determining the selection of software, the absence of choices is seen as a way for the software provider to lock customers into their services. Amazon Redshift, unlike Snowflake and Snowflake, is only accessible through AWS. If you’re a customer from Azure, GCP, or Oracle Cloud and are looking to examine the options offered by these cloud providers before you decide to use Amazon Redshift.

Amazon Redshift is not 100 100% controlled

Although the tools provided by Amazon can reduce the need for a database administrator full-time, they do not completely eliminate the need for one. Amazon Redshift is known to be unable to handle storage effectively in a system that is prone to frequent deletions. The maintenance of sort order is crucial to achieving effective performance metrics. The aspects that affect the databases aren’t widely known to developers, and some might argue that they ought to not be concerned. They would be right.

The present advancements in technology for databases can remove the requirement for users to comprehend these topics of administration for databases and also manage the database to ensure optimal performance, without the need for an administrator for the database. Snowflake as well as Oracle Autonomous data warehouses have achieved huge progress in this direction. Amazon Redshift has already released many features such as automatic table sorting as well as automatic vacuum deletes and automated analysis, which are proving that it is making progress in this area.

Concurrent execution

It is well common problem when working with MPP databases. In a scenario where many concurrent users are working on the same queries Redshift may encounter issues with performance. Additionally because of the lack of separating storage and computing reading workloads, read loads are affected by the powerful writing that is taking place within the database because 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 continuous resizing of clusters and the capability is as a disadvantage in a market that has competitors who offer the ability 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.

The choice of keys affects performance and costs

In the world of cloud computing performance is the price.

Users should carefully plan their strategies for key distribution and sorting while paying attention to the future needs. They should regularly review the accuracy of their type of key and distribution keys since more data is being introduced into Amazon Redshift. Amazon Redshift data warehouse. An unoptimal design could increase the cost associated with your Redshift data warehouse due to the fact that the performance of the system declines and, in turn, causes problems with satisfaction of users. It is possible to increase the size of the cluster to tackle the issue however, it will increase the cost. But, a carefully planned method allows businesses to reap the maximum benefit the Amazon Redshift investment before scaling up.

Master Node

It plays an essential function within the Redshift architecture as it orchestrates queries such as allocation, execution and aggregation, as well as the results of their execution. Clients only interact via the master Node and thus, a master node is the only point of failure to the system.

This is not a serverless design.

Amazon Redshift is an old timer when it comes to cloud-based data warehouses. Redshift has its limitations and was developed many years back. A serverless design allows the manufacturer to perform more optimization of the hardware, which results to lower costs for clients. Prices will drop in the event that the same hardware is used by three people instead of. one. Old guards benefit because they have been around for a long period of time and constantly innovating. They can be more beneficial than the perceived disadvantages, and at times they don’t.
