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

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

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

Code Level Architecture

Scale Aware Code

Programming Abstraction

Scale Agnostic Code

Bottom layer understands that the application is distributed across multiple machines

Top layer written without worrying about scaling issues

A small abstraction layer links the two together

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”
