Platform-as-a-Service (PaaS) is often regarded as the next frontier of Cloud Computing. PaaS allows application developers to write software that leverages a common set of powerful services like caching and queuing. It also enables deployment of code in a highly automated fashion, without the typical overhead associated with configuration and packaging. PaaS lets you speed up SDLC and deliver elastically scalable and operationally efficient platforms to run data intensive applications. VMware vFabric along with Cloud Foundry is becoming a de facto standard for how to do all of this. Using real-world examples and demonstrations we share with you a roadmap to next-generation Cloud-Enabled applications using VMware and EMC technologies.

9. Build Elastic App Architectures With PaaS
The ability of an application to automatically adjust the infrastructure resources it uses to
accommodate varied workloads and priorities while maintaining availability and performance.*
Web Application Platforms Elastic Application Platforms
Mostly manual scaling Elastic scaling (right capacity in time)
Three-tier application architectures Highly distributed architectures
Manual workload management Automatic, policy-based workload management
Data at arm’s length Data and logic intermingled
Static, homogeneous containers Fabric of diverse containers
Key client: browser Many clients and consumers
Interdependent services Autonomous modules
* A great definition by Forrester, internet reference

10. PaaS Is NOT “Plug And Play”
Modern Design Principals For Modern Platform Capabilities
 Enable Scale-Out At Each Tier Of Your Application
 Avoid Persistent State In Your Application Tier
 Keep Data Close To Workers
 Avoid A Single Centralized Database
 Expect Dependencies & Configuration To Be Injected
 Use An Event Driven Architecture
 Avoid Traditional Clustering
 Avoid Distributed Transactions

11. The Definition Of Scalability
Scale Means More Scale… Right?
 Scalability Is Not All About More Scale
 Often, It Is About Less Scale (Most Of The Time),
With The Option For More Scale (When Needed)
 Clients Want To Use Commodity (Read: Cheap)
Hardware And Software To Reduce Cost
 Clients Want To Avoid Over-Provisioning Hardware
 Clients Want The Flexibility To Modify Hardware
Allocations In Real Time

worrying about scaling issues
Scale Agnostic Code
A small abstraction layer links the

Scale Aware Code
Bottom layer understands that the application is
distributed across multiple machines

16. Evolution Of The Middleware Platform
“Over time, the lower layer of these
applications may evolve to become new
platforms or middleware which simplify the
creation of scale-agnostic applications”
