• How to create a simple Cassandra Cluster on AWS

    What is Cassandra? Apache Cassandra is a free and open-source distributed wide column store NoSQL database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Wikipedia Apache Cassandra is a high performance, extremely scalable, fault tolerant (i.e. no single point of failure), distributed post-relational database solution. Cassandra combines all the benefits of Google Bigtable and Amazon Dynamo to handle the types of database management needs that traditional RDBMS vendors cannot support.

  • A Manager's Guide to the Database Galaxy - Part 6 (NoSQL - Key Value Stores)

    PART 6 In the last blog we considered different Wide Column Store databases and examined some facets of performance and associated costs. In this blog we look at another type of NoSQL databases, the much simpler Key Value Stores. Offerings from different vendors and examined in an attempt to highlight some of the key differences between otherwise similar technologies. We also consider the differences in performance and what costs are associated to running each database on premises or in the cloud, so that it may become clearer and easier to recognize the database that best suits your needs.
  • Oracle Cloud Infrastructure (OCI) Benchmarking Oracle's DBaaS against RDS - A Performance Comparison - Part II

    The following Blog discusses the results of testing I/O performance of an Oracle Database running on Oracle’s Cloud X7 generation instances compared to the same database running on Amazon Web Services (AWS). The Oracle Stress Testing Tool (SLOB) was used to test the performance.

    The results suggest that it is possible to achieve almost double the performance at less than half the cost on Oracle Cloud compared to AWS RDS.

  • A Manager's Guide to the Database Galaxy - Part 2

    PART 2 This is the second blog in our series comparing different database management systems. In the last blog we looked at different data structures and their corresponding database management systems. In this part of the blog series we will consider different use cases best suited to each system. Introduction All Database Management Systems have their ups and down when applied to specific situations or workloads, but each DBMS has at least one use case that it is particularly suited for (unless we are talking about a multi-model DBMS then more than one use case may apply).
