Why You Should Care

4
Most Cloud-Based Systems are Lacking Architecture

5
Thus, many clouds are not meeting expectations.

6
• 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.
The results:

7
• Not understanding how to make architectures scale.
• Not dealing with tenant management issues.
• Not understanding that security is systemic, and impacts performance.
• Not understanding the proper use of services (Yes, that means SOA).
• Tossing technology at the problem.
• Listening to the wrong people.
Common Mistakes

8
• 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.
The Multitenant Thing
“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.”

Virtualization is Not Always a Requirement

• Migration to a Cloud
– Business Systems
– Infrastructure
• Building on a Cloud (PaaS)
• Building a Hybrid Cloud

General Architecture Patterns to Follow

14
1. Governance
2. Regulatory Compliance
3. Security & Identity Management
4. Business Continuity
5. Process and Services
6. Data Management
7. System Integration
8. Resource Skills & Knowledge
9. Application Readiness
10. Network Readiness

Build a Solid Foundation:
Architecture Roadmap General Guidance
• 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

16
“as-is”

17
“to be”

19
• 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.
General Rules & Guidelines

20
Use Case:
General Business System Migration to the Cloud

21
• Break the system down to it’s component parts, understanding each part.
• Rethink the database, it’s typically a mess.
• Rethink the system as sets of services/API, watch the granularity.
– Data services, transaction services, utility services
• Create a security and governance plan.
• Consider the user interfaces.
• Consider device interfaces.
• Migrate only the components to the cloud that will provide the best value.
The General Idea

22
Good News
• Most cloud platforms provide the tenant management features for you.
• Most cloud platforms manage the resources for you.
• The cloud platforms are getting better.
Bad News
• Security is still your problem.
• Application and service design is still your problem.
• Testing can be a hassle.
• Watch out for immaturity if standards.
