AWS OLAP vs Azure OLAP: What is the Difference?

Today all organizations have large pools of data collected from many sources. This data must be interpreted correctly at the right time to make a sound decision. A data hub in the cloud can provide information to all users from any part of the world. 

Online Analytical Processing, commonly known as OLAP, helps users analyze a vast amount of data in multidimensional views and hierarchies. Also, OLAP tools give better performance than traditional database access tools. 

OLAP performs multidimensional analysis on large volumes of data from a data warehouse at high speeds. Most businesses have data broken down into multiple categories for presentation, analysis, or tracking. OLAP gets data from several relational data sets and rearranges it in a format that supports fast processing and insightful analysis.

Redshift AWS OLAP rocks the world as a data warehouse because of the blend of entry-level affordability, cost efficiency, and easy addition of nodes to the data warehouse.

Redshift is an OLAP system provided by AWS, and Azure Analysis Services is an OLAP system provided by Azure.

Amazon Redshift vs Azure Analysis Services

Amazon Redshift data warehouse is a swift petabyte level data storehouse that stores and processes the data on several nodes. It enables companies to build powerful applications and generate reports. Redshift consists of a collection of nodes arranged into a group called a cluster. 

Each cluster has one or more databases, a leader node, and one or more compute nodes. Nodes depend on the complexities of queries and the amount of data needed to be imported to Redshift. The nodes are scaled up and down quickly, and the user can change the number or type of nodes in the data warehouse. 

Redshift uses efficient techniques to get a high level of query performance on vast amounts of data. It can be installed quickly and create a cluster of nodes. It can provision the nodes, handle connections between them, and secure the cluster in a few minutes. 

All data and information written to a node is automatically replicated to other nodes and backed up continuously. Columnar data storage is a significant aspect of Amazon Redshift. Other advantages are massive parallel processing and cost-effectiveness.

Microsoft Azure is a well-known SQL data warehouse that uses Massive Parallel Processing. Azure SQL warehouse utilizes blob storage to store data. There is a control node, and multiple compute nodes to run queries. After processing, results go to the control node from the compute node and are given to the user. 

Azure has a minimum of three copies of the same data stored in the same data center. It is done to ensure the resiliency of the storage. 

Different levels of resiliency are obtained by choosing Geo-redundant storage, Zone-redundant storage, or Read-only Geo-redundant storage. Data security is built at various levels as per customer requirements. Data is encrypted before being stored. Azure provides a single pane of view of the hybrid environments.

Amazon Redshift and Azure synapse analytics can scale up and down and perform well under various load levels, even when it is heavy. Basic access privileges for the data in Amazon Redshift are controlled through an AWS account and Identity and Access Management account. Azure keeps the data secure and doesn’t share the data with advertiser-supported services or mine it for purposes like marketing research.

Redshift provides high-performance and efficient storage using data compression, columnar storage, and zone maps. Azure Synapse Analytics brings together data integration, data warehousing, and big data analytics through a single user interface.

Data warehouses like AWS OLAP are the best choice for organizations to handle large amounts of data quickly and securely. Organizations can start small and expand with time as data volume and the number of users increases.
