• 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 in the Cloud - Part 7 (NoSQL - Graph Databases)

    PART 7 In the last few blogs we examined a variety of different NoSQL databases and considered some of their appropriate domains and use cases. In this edition we conclude our multi-part database blog series by considering Graph database offerings from different vendors. This is done 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.
  • 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.
  • A Manager's Guide to the Database Galaxy - Part 5 (NoSQL Wide-Column Stores)

    PART 5 In the last blogs we examined a variety of different database types and considered some of their appropriate domains and use cases. In this blog we look at actual NoSQL Wide Column Store offerings from different vendors, 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.
  • A Manager's Guide to the Database Galaxy - Part 4 (NoSQL Document Stores)

    PART 4 In the last blog we examined different relational database offerings and considered some of their unique features and differences. In this blog we will compare and evaluate different NoSQL offerings, starting with Document Stores. This is done 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.
