Cloud data warehouse guide: Using Redshift, rival platforms

Amazon Redshift put cloud-based data warehouse platforms on the map, but the field has grown to include products from IBM, Microsoft and others. Learn about cloud data warehousing options and issues in this guide.

Introduction

When Amazon Web Services (AWS) announced its Redshift data warehouse technology in late 2012, the cloud computing vendor did more than just introduce a new product offering -- it also opened the doors to the cloud data warehouse market as a whole. Before the debut of Amazon Redshift, data warehousing was essentially an on-premises initiative, with data migration and security issues playing big roles in keeping warehoused stores of corporate information inside the walls of organizations. Redshift made the idea of deploying a data warehouse in the cloud viable, with at least the promise of substantial cost savings compared with installing and running traditional data warehouse systems.

By March 2014, Redshift had gained AWS a place among the vendors ranked in Gartner Inc.'s annual Magic Quadrant report on data warehouse platforms and analytical databases. Since then, it also has been joined by a variety of cloud-based data warehouse competitors, from startups and major vendors alike. The data warehouse as a service options now available to prospective users include IBM's dashDB and Microsoft's Azure SQL Data Warehouse, as well as technologies from smaller companies such as Snowflake Computing and CoolaData. In addition, Oracle, Teradata and other data management vendors offer cloud-based versions of their data warehouse database platforms.

In addition to the potential savings, cloud data warehousing can enable user organizations to quickly get systems up and running. Cloud services can also be easily scaled up or down as data and business needs change. But fundamental data management processes -- data integration, data quality, data governance, master data management -- still need to be applied to information that's warehoused in the cloud. And moving on-premises data to the cloud remains an issue: In a podcast Q&A with SearchDataManagement, Rick Sherman, founder of consultancy Athena IT Solutions, said it can be cost-prohibitive and take more work than is worthwhile, "especially if you have an extensive number of data sources and … a large volume [of data]." As a result, cloud data warehouse users often are organizations that run business applications in the cloud, generating much or all of their data there to begin with.

In this Essential Guide, you'll find more information about Amazon Redshift and other cloud platforms for data warehousing, plus expert insight and real-world advice on managing cloud data warehouses. It also includes articles on general data warehouse best practices and trends.

1The state of data warehousing-

Data warehouse trends, analysis and advice

Hadoop data lakes and other big data systems capture a lot of attention and headlines these days, but data warehouses still have their place in most organizations, for supporting analysis of both current and historical data. Moving them to the cloud changes the warehousing game somewhat, adding the usual concerns about housing data off premises, but potentially reducing costs as well as the complexity that often surrounds launching and maintaining data warehouses. The articles in this section provide expert insights on the continuing need for data warehousing and the potential advantages -- and risks -- of cloud data warehouse platforms.
