Application LeveL Multi-tenancy

the classic way

APPLICATION LEVEL MULTI-TENANTS 

Document Store 
Security
Life Cycle
Indexing
Versioning

all clients share the same application

application manages data and configuration partitionning

Application level Multi-Tenancy - Data Isolation

 

  • Data Partitioning
    • Repository
      • Security Policy
      • "Domain based"
    • Elasticseach
      • same index
    • Users/Groups
      • filtering on per tenant basis

Logical isolation

Application level Multi-Tenancy - Data Isolation

 

  • Data Partitioning
    • Repository
      • Separated repositories
        • MongoDB
      • Separated Blob Stores
    • Elasticseach
      • per tenant index
    • Users/Groups
      • different directories

Physical isolation

Application level Multi-Tenancy - Configuration

  • Share everything
    • One Application : One configuration
       
  • All tenants share the same configuration
    • extension points contributions
       
  • ​Tenant isolation is done via filtering
    • ​all doc types are defined for all tenants
    • UI filters access / hides part of it

Application level Multi-Tenancy - Configuration

Some Limitations

Shallow isolation

  • quota management is difficult 
  • customization options are constrained
     

Monolithic 

  • same version, same component set
  • same upgrade and maintenance policy
     

Scaling number of tenants adds complexity

  • scale out is not that easy (i.e. move a tenant)
  • per-tenant Backup/Restore is not easy
  • Heterogeneous deployment units
             
    VM level / JVM level / App level 

But

Well adapted for lightweight customization.
 

Easy first step.

Multi-tenanTS INFRASTRUCTURE

Cloud native approach

Container Level Multi-tenants

rely on infrastructure to provide tenants isolation

application does not need to be impacted 
 

Bake custom images

Bake custom images

Deploy custom images

Principles

Docker   containers !

Leverage  AWS infrastructure 

Container Level Multi-tenants

Unlimited Customization
 

Flexibility of isolated deployments

Full security Isolation & Quotas

  • Could be VM based
    • AWS ECs / CloudFormation
    • vSphere
       
  • Container based
    • Rancher / Docker / Kubernetes
    • OpenShift V3 / CloudFoundry

Build Your Own Application  

Infrastructure Cost

Overhead is not that significant
(Docker is lightweight, JVM ~500MB)
 

Anyway, provisioning automation is needed to scale
(DNS, DB, Backup ...)

Nuxeo & Docker

  • Working on Docker deployment since 2012 !
    • Working on Docker based PaaS
      • CoreOS / Fleet
      • Swarm / Kubernetes
      • Rancher

         
  • All existing PaaS solutions converge to this approach
    • OpenShift 3 is now Docker/Kubernetes based

Multi-Tenants ?

Choosing the right approach

Decision Points

  • Per tenant customization
     
  • Per tenant isolation requirements
     
  • Per tenant revenue model
     
  • Differences between small and large customers
     
  • Number of tenants
     
  • Hosting practices

Different solutions for Different clients

  • Small customers with entry level offering
    • fully shared infrastructure
    • limited customization
       
  • Medium customers with more security concerns
    • shared configuration
    • isolated storage
    • limited customization
       
  • Platinium customers
    • infrastructure level isolation
    • full Studio power for each customer
