Cloud　management　faces　with　great　challenges,　due　to　the　diversity　of　Cloud　resources　and　ever-changing　management　requirements.　For　constructing　a　management　system　to　satisfy　a　specific　management　requirement,　a　redevelopment　solution　based　on　existing　management　systems　is　usually　more　practicable　than　developing　the　system　from　scratch.　However,　the　difficulty　and　workload　of　redevelopment　are　also　very　high.　As　the　architecture-based　runtime　model　is　causally　connected　with　the　corresponding　running　system　automatically,　constructing　an　integrated　Cloud　management　system　based　on　the　architecture-based　runtime　models　of　Cloud　resources　can　benefit　from　the　model-specific　natures,　and　thus　reduce　the　development　workload.　In　this　paper,　we　present　an　architecture-based　approach　to　managing　diverse　Cloud　resources.　First,　manageability　of　Cloud　resources　is　abstracted　as　runtime　models,　which　could　automatically　and　immediately　propagate　any　observable　runtime　changes　of　target　resources　to　corresponding　architecture　models,　and　vice　versa.　Second,　a　customized　model　is　constructed　according　to　the　personalized　management　requirement　and　the　synchronization　between　the　customized　model　and　Cloud　resource　runtime　models　is　ensured　through　model　transformation.　Thus,　all　the　management　tasks　could　be　carried　out　through　executing　programs　on　the　customized　model.　The　experiment　on　a　real-world　cloud　demonstrates　the　feasibility,　effectiveness　and　benefits　of　the　new　approach　to　integrated　management　of　Cloud　resources　©　2014,　Chen　et　al.;　licensee　Springer.
