1 Cloud Management System (CMS) Wiqar Chaudry Solu9ons Engineer Senior Advisor

2 CMS Overview he OpenStack cloud data management system features a canonical data modeling framework designed to broker context sensi9ve data to distributed applica9ons. Key features include: unable consistency and availability guarantees based on transac9ons types emand based replica9on of canonical data to various data management systems (Cassandra, Hadoop, Mongo, MySQL, etc ) ynamic scalability for cloud- scale applica9ons

3 CMS - Components Network level resource manager monitors all physical and virtual compute resources par9cipa9ng in a CMS. his component is responsible for federa9ng all requests to and from CMS Agents CMS manager Compute level agents manage all data and logic processing on physical or virtual hosts. CMS agent CMS agent Supported databases and data management systems. Columnar (Read op9mized) Rela9onal (Write op9mized) ocument (ynamically structured) Canonical data and persistence maintain a golden copy of all data in a consistent state. Canonical data Canonical persistence (Block storage) <Variable>

4 CMS: Fundamental Building Blocks Connec<ons Schemas Mappings Canonical Schemas A?ributes Logic Rule Workflow Rule Rule A logically grouped collec9on of the above metadata objects represents a canonical mapping object. he persisted state of these objects enables sta9c and dynamic analysis of the CMS environment. Func9onal metadata enables flexibility and reusability. Page 4

5 Metadata: Sources and argets Connec<ons Schemas Connec9ons are reusable ar9facts that capture informa9on required to connect to a source or target. Users are able to store this connec9on informa9on and reuse it when extrac9ng or loading data. Schemas define the physical layout, format, and data types of data within a source/target object. Schema ar9facts are also stored and can be reused. Page 5

6 Metadata: Canonical A?ribute Ar<facts Schema Mapping Sets Schema A?ributes Schema Schema mapping sets define the rela9onship between physical source schemas to internal canonical data objects. Schema mapping sets can have a one- to- many rela9onship between physical and logical schemas. A logical data table is a collec9on of one or more a]ributes that defines a data table within the CMS. An a]ribute schema is the collec9on of metadata required to define a managed a]ribute for use within a data table schema. *A?ributes for all intents and purposes are simple key value pairs. Page 6

7 Metadata: Applica<on Logic Logic Workflow Rule A Logic Rule is a reusable object that contains transforma9on logic. A Workflow Rule contains logic that replicates, moves, or makes data available within a requested context. A Rule is a reusable object that contains both data and workflow rules. Page 7

Single canonical representa9on of data across public and private could environments Context sensi9ve bi- direc9onal replica9on of data Object and collec9on level consistency tuning Enables collabora9ve data management strategies across enterprises High availability an elas9c scalability.
