The document discusses best practices for cloud architecture. It notes that many current cloud systems lack proper architecture and do not meet expectations due to issues like inefficient resource utilization, outages, lack of security and tenant management. Common mistakes made are not understanding how to scale architectures, deal with tenants, implement proper security, or use services correctly. The document provides guidance on developing a solid cloud architecture, including determining business needs, designing with services in mind, creating security and governance plans, and migrating only components that provide value to the cloud. It emphasizes focusing on core services like data, transactions and utilities, and building for tenants rather than individual users.

- 6. © 2013 Cloud Technology Partners, Inc. / Confidential 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. © 2013 Cloud Technology Partners, Inc. / Confidential 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. © 2013 Cloud Technology Partners, Inc. / Confidential 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.” Source: Wikipedia

- 19. © 2013 Cloud Technology Partners, Inc. / Confidential 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. © 2013 Cloud Technology Partners, Inc. / Confidential 20 Use Case: General Business System Migration to the Cloud
- 21. © 2013 Cloud Technology Partners, Inc. / Confidential 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. © 2013 Cloud Technology Partners, Inc. / Confidential 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. Good News / Bad News
