Getting Cloud Architecture Right the First Time Ver 2

This document discusses best practices for designing cloud architectures. It recommends focusing on primitives like data, transaction, and utility services and building for tenants rather than individual users. The document also warns that security and governance must be addressed systematically. It provides an example reference architecture for migrating an existing business system to the cloud by breaking it into component services and redesigning the database.
Getting Cloud Architecture Right the First Time Ver 2
- 1. How to Get Cloud Architecture and Design Right the First Time David S. Linthicum Blue Mountain Labs david@bluemountainlabs.com
- 2. Abstract So, what are the proper ways to design, build, and leverage cloud computing systems? What are the steps to success? What are the emerging best practices? How does SOA fit in? In this session we’ll answer these questions, and more, covering the right and wrong ways to leverage, design, and build cloud-based systems and infrastructure. Going beyond the hype, this includes advice from those currently in the trenches who make cloud computing work for the Global 2000 and government. The audience is anyone who will soon fight to make cloud computing work for their clients, employers, and/or investors, and need to knock it out of the park the first time.

- 6. Why You Should Care
- 7. Most Cloud-Based Systems are Lacking Architecture
- 8. Thus, many clouds are not meeting expectations.
- 9. 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.
- 10. 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.
- 11. 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

- 18. 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 •

- 21. deploy
- 22. 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.
- 23. Use Case: General Business System Migration to the Cloud
- 24. The General Idea • 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.
- 25. Good New/Bad News • 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.
