Consider the guidelines and specific questions in the four major categories below when constructing an RFP to evaluate the various distributions of Hadoop available today.
Higher software performance gives you more from your hardware, thus lowering your total cost of ownership.
Despite their common Hadoop roots, not all distributions are the same. When putting together an RFP for Hadoop, pay particular attention to performance, scalability, reliability, manageability, and data access.
You want your Hadoop deployment to run fast. This not only gets jobs and work done faster, but also delivers more value from your hardware so you can lower your total cost of ownership.
Scalability ensures that your big data can continue to grow without outpacing your system capacity. Consider the different aspects in which your data will grow, including overall data volume, number of files, and number of database (HBase) records.
RFP questions you should ask prospective Hadoop vendors about performance and scalability include:
Understand the differences between each vendor’s enterprise-grade high availability, data protection, and disaster recovery capabilities.
You should expect Hadoop to be subject to the same reliability expectations as every other enterprise software system.
Questions to ask prospective Hadoop vendors about reliability include:
Managing big data can be daunting, so you should seek a distribution for Hadoop that lowers the administrative burden.Manageability, including multi-tenancy, is key to ensuring production success and continued growth.
Questions to ask prospective Hadoop vendors about manageability include:
Hadoop is often used to capture data from across many data sources and systems, so interoperability and security are critical aspects of any Hadoop deployment. Real-time data access is important when deploying Hadoop in an existing enterprise architecture.
Questions to ask your prospective Hadoop vendor about data access include:
Selecting your Hadoop vendor based on this criteria will ensure your deployment is about business value and competitive advantage, and not about spending excessive time on building and maintaining infrastructure.
