Most Cloud-Based Systems are Lacking Architecture
The results:• Inefficient utilization of resources.• Resource saturation.• Lack of elasticity and scalability.• Lack of security and governance.• Frequent outages.• Bad or no tenant management.• Other very bad things.
Common Mistakes• Not understanding how to make architectures scale.• Not dealing with tenant management issues.• Not understanding that security is systemic.• Not understanding the proper use of services.• Tossing technology at the problem.• Listening to the wrong people.• Managing-by-magazine.
The Multitenant Thing• No two multitenant architectures are alike.• Needs to be effective in the context of the problem.• Needs to leverage best architecture practices.• Needs to practice isolation and protection. “With a multitenant architecture, a software application is designed to virtually partition its data and configuration so that each client organization works with a customized virtual application instance.” Source: Wikipedia

Architecture Roadmap Where to begin Build a solid foundation: • Determine business drivers • Understand: data, services, business processes and system integration points • Design a “cloud-friendly” enterprise architecture roadmap that leverages Services Oriented Architecture (SOA) • Determine an integration strategy for internal and external systems • Outline a migration path for legacy systems to the new architecture Leverage SOA to build a sturdy and agile foundation for the Cloud •
General Rules and Guidelines• Focus on the primitives. • The best clouds are sets of low level services that can be configured. • Data services • Transaction services • Utility services• Leverage distributed components that are centrally controlled.• Build for tenants, not users.• Don’t lean too much on virtualization.• Security and governance are systemic.
