Migration from Microsoft FAST to Apache Lucene Solr

Is your company using Microsoft FAST ESP on a Linux platform?  Unfortunately, Microsoft announced in 2010 they will cease technical support for FAST ESP 5.3 after it’s 5 year life cycle for anyone using Linux as their operation system. Migration to another search platform will be a priority, and business leaders and technology professionals are looking closely at Lucene Solr as a solution.

We can assist your organization in any stage of a migration. We can perform an evaluation of your current architecture, draft a plan for migration, work with your internal team on the migration or just consult as needed. Whatever your specific needs are, we can help you achieve your goals. Read our White Paper released February 2012 that presents a Case Study on migration. The paper discusses:

  • Loading millions of documents into Solr indexes
  • Evaluation and recommendations for tools to bridge the features gap
  • Migrating custom pipeline code to Pypes with minimal changes
  • Proven ROI after a complete migration

Additionally, we have presented on the subject of FAST ESP to Lucene Solr migrations for the Lucene Revolution Conference in Boston, MA (2010 Slides: Migration from FAST ESP to Lucene Solr (PDF) (pdf:4,067,091) ) and at the Apache Lucene Eurocon (web site dead) Barcelona (October 2011). Watch our VP of Search Technology Michael McIntosh’s presentation on FAST to Lucene Solr Migration below. If you like what you see, contact us to explore a Solr migration solution.

Big Data

Big Data is data that has outgrown the processing capacity of traditional database systems. It is data that is too big, moves too fast, or cannot be contained within your database architectures. But Big Data has immense value, because of the information trapped inside. To leverage this value and unlock the data’s potential,  it must be processed differently to extract meaningful information.

Our software engineers have experience working with datasets containing several terrabytes of data. We use technologies like Hadoop and HBase to process this data and indexers like Solr and ElasticSearch with JSON to index and extract meaningfull information from enormous data sets.  Combining these technologies creates a search engine that powers discovery, business intelligence, and analytics.

Cloud Computing Benefits

Cloud computing offers application vendors, publishers and researchers augmented capacity and an exceptional platform for testing, development and one-off projects, web based applications, parallel or very large batch jobs, scientific computing, and rich media processing.

Agility:

Benchmarking and prototyping in a properly sized, dedicated environment supports agile development for faster time to market. Because the service is on demand, you can start trying your ideas immediately without needing to fully understand the size and scope of the finished product. It will change the way you work.

Elasticity:

Cloud Computing offers the ability to massively scale-up or scale-down the dedicated resources to handle large user volumes, seasonal fluctuations in demand or a large one-time computation. It eliminates the need to plan for maximum capacity in advance and allows applications to programmatically add or remove nodes as needed.

No capital expenditure:

Explore your needs before investing in infrastructure. Computational infrastructure as an operational expense allows for significantly faster deployments and exactly enough capacity for your present needs and your future growth.  With the new technology, application vendors can offer faster deployments to their customers and researchers can get faster results without needing months to go through a full cycle of hardware specifications, procurement, and configuration at internal or third party data centers.

Pay-as-you-go pricing:

Allows you to pay only for what you use. Billing for computation resources can be directly and appropriately attributed to the correct customer, project or grant.

Consistency:

Ability to configure an easily deployable, reproducible and shareable computational environment accessible from anywhere in the world from a web browser.

Supports risk-taking:

Eliminates the concern of bringing down the machine or blocking the higher priority work of others. Ability to provide an isolated, temporary development environment for new team members to get up to speed or run new software through rigorous and resource intensive testing.

Green:

Cloud computing uses servers that can be located anywhere in the world to take advantage of renewable energy sources and lower cooling requirements. Shared physical hardware and right-sized machine resource allocation mean less excess capacity consuming energy.
