  6. 6. What is the Problem with Big Data ► Caching ► Master/Slave ► Master/Master ► Cluster ► Table Partitioning ► Federated Tables ► Sharding Quelle: http://www.codefutures.com/database-sharding/19.11.2012 6 NoSQL in der Cloud – Why?
  7. 7. NoSQL Basics – CAP Theorem Consistency Each client always has the same view of the data Availability All clients can always read and write Partition tolerance The System continues to operate despite arbitrary message loss Quelle: http://blog.nahurst.com/visual-guide-to-nosql-systems19.11.2012 7 NoSQL in der Cloud – Why?
  8. 8. ACID-BASE ACID BASE Atomicity Basically Available ► all or nothing rule ► the system does guarantee availability, in terms of the CAP theorem Consistency Soft-State ► any transaction the database performs will take it from one consistent state to ► the state of the system may change over another time, even without input Isolation Eventual Consistency ► the system will become consistent over ► no transaction should be able to interfere time, given that the system doesnt with another transaction at all receive input during that time Durability ► once a transaction has been committed, it will remain so Quelle: http://stackoverflow.com/questions/3342497/explanation-of-Quelle: http://en.wikipedia.org/wiki/ACID base-terminology19.11.2012 8 NoSQL in der Cloud – Why?
  9. 9. Things to think about!!! ► Scalability ► High Availability ► Caching ► Architecture ► Load Balancing ► Queuing ► Data Handling ► Federation ► Serving Files ► Storing Files Quelle: http://cloudscaling.com/blog/cloud-computing/up-out-centralized-and-decentralized19.11.2012 9 NoSQL in der Cloud – Why?

  13. 13. What ist means Query Developer Data is easily and quickly read/stored More technologies to have fun with using primary key Broader choice of persistence stores Denormalize data for commonly used queries Probably Cross Store Persistence ► Store name, firstname etc in RDBMS ► Shema Design is optimized for the most common Use-Cases ► Store followers in Graph database ► Store Content in RDBMS ► Store User Generated Content in Document database Quelle: http://www.slideshare.net/adessoAG/no-sql-935510919.11.2012 13 NoSQL in der Cloud – Why?

  19. 19. mongoDB – ReplicationReplica Sets► A replica set consists of two or more nodes that are copies of each other► The replica set automatically selects a primary (master).► Drivers can automatically detect when a replica set primary changes and will begin sending writes to the new primaryWhy Replica Sets► Automated Failover► Read Scaling (slaveOkay Method)► Maintenance► Disaster Recovery Quelle: http://www.mongodb.org/display/DOCS/Replica+Sets19.11.2012 19 NoSQL in der Cloud – Why?
