Abstract: 

We are all used to thinking that from a performance perspective distributed storage symmetrical systems perform best because of the weakest link in the chain effect. This presentation discusses situations in which asymmetrical implementation reduces the cost of implementation and improves the performance. This happens because of the public cloud resource variety and price structure. The presentation discusses the model and the details for cheaper and more performant asymmetrical Ceph deployment

  • Conditions under which symmetrical systems perform best
  • Conditions where we can break the symmetry
  • The effect of the pricing model on the storage architecture
