SaaS Applications Charateristics

Multi-tenancy

Application customization functions: branding, process enactment…

Application management functions: self-service tenants CRUD

Application monitoring functions: uptime, user counts, billing…

Scaling becomes critical

Security is paramount

Dealing with multi-tenancy: Options

Project-level: Lightweight, low isolation– Some cross-project visibility– Cross-tenant invariants

Same software version, IP filtering, VPN/VLAN settings, process choices, etc.– Very economical– A bit of a mismatch:

Binds a notion of work-scope (project) to a privacy notion (tenant) Application level: Medium-weight, high isolation

– No shared repository– Can bind applications to specific IP addresses/virtual network adapters– Still share machine-level facilities

Virtual machine level: Heavyweight, high isolation– Expensive – one VM per ‘tenant’– Enables a logical “shared nothing” model

IBM Deployment Planning and Automation lifecycle

Govern and share deployment topologies and deployment workflows.

Discover the existing

environment upon which we need to

deploy the application.

Plan your desired deployment topology

and publish automation

instructions. Automate infrastructure provisioning, middleware configuration, and application installation to repeatedly setup environments.
