2 likes684 views
The document discusses the rapid development of cloud-ready applications through a framework called Grady, which utilizes Groovy and Grails technologies. It addresses challenges such as multi-tenancy, identity management, and data privacy while promoting a fast-paced, agile development approach. The framework aims to enhance productivity and innovation for companies by providing efficient solutions to build applications quickly and effectively.

- 13. Grails & Groovy q Grails: þ OSS, Groovy-based high-productivity framework inspired by Ruby on Rails and following the "coding by convention" paradigm þ Grails applications can run in standard Java servlet containers. q Groovy: þ OOP language for the Java platform þ Dynamic language with features similar to those of Python, Ruby, Perl, and Smalltalk þ Can be used as a scripting language for the Java Platform, is dynamically compiled to Java Virtual Machine (JVM) bytecode, and interoperates with other Java code and libraries.

- 15. Core Plugins q Spring Security Core: Secure applications using the powerful Spring Security library þ Spring Security Configuration Info: Provides a basic UI to view the security configuration þ Spring Security LDAP: Support for LDAP and Active Directory authentication þ Spring Security OpenID: Support for OpenID authentication q Hibernate Envers: þ Plugin to integrate grails with Hibernate Envers þ Easy Entity Auditing. All that you have to do is annotate your persistent class or some of its properties, that you want to audit, with @Audited q Multi Tenant Single DB:
- 16. Twitter Bootstrap & Less q Bootstrap: þ Developed by Twitter as a framework to encourage consistency across internal tools þ No.1 project on GitHub with 71,000+ stars and 26,000+ forks þ The most popular HTML, CSS, and JS framework for developing responsive, mobile first projects on the web q Less: þ CSS pre-processor, meaning that it extends the CSS language, adding features that allow variables, mixins and functions þ Make CSS that is more maintainable, themable and extendable
- 17. Multi Tenancy: Data Architecture q Separate DB: Each tenant has its own set of data that remains logically isolated from data that belongs to all other tenants. þ Metadata associates each database with the correct tenant, and database security prevents any tenant from accidentally or maliciously accessing other tenants' data. q Separate Schema: House multiple tenants in the same database, with each tenant having its own set of tables that are grouped into a schema created specifically for the tenant. þ When a customer first subscribes to the service, the provisioning subsystem creates a discrete set of tables for the tenant and associates it with the tenant's own schema. þ A significant drawback of the separate-schema approach is that tenant data is harder to restore in the event of a failure. If each tenant has its own database, restoring a single tenant's data means simply restoring the database from the most recent backup. q Shared Schema: The same database and the same set of tables to host multiple tenants' data. þ A Tenant ID column associates every record with the appropriate tenant þ The shared schema approach has the lowest hardware and backup costs, because it allows you to serve the largest number of tenants per database server þ However, it may incur additional development effort in the area of security, to ensure that tenants can never access other tenants' data, even in the event of unexpected bugs or attacks
- 18. Tradeoffs: No Silver Bullet q Grails þ Tight Coupling þ Anti-patterns þ (Some) Immature Plugins q Twitter Bootstrap þ A dark future where the entire web looks like the Bootstrap example page þ Heavy-handed, Prescriptive

- 21. So what's the ruckus about? “Smarter. Faster. Better. These are today's words when talking about business. And, about development too. Nowadays, we’re all in the cloud and some of us have already faced a simple question without a simple answer: how to build better apps faster? There are a multitude of challenges arising when trying to achieve this ambitious goal while maintaining a productive pace for delivery and innovating at the same time. How do I isolate tenant data, how do I manage identities across federated clouds, how can I migrate legacy apps, how do I ensure single sign on in heterogeneous cloud environments (of course everything Smarter. Faster. Better.) We now have a simple answer to some of these technical questions: our own rapid development framework, based on open source technologies seamlessly glued together, of course, for cloud-ready applications - because this is what we do. We're inviting you to a practical discussion on how the R&D department can play a major role in delivering every business' goal: time to market. Smarter. Better. Faster.” Vlad, R&D Monica, Marketing
