PaaS Ecosystem Overview

Dmitry Meytin December 2015

What is PaaS?

NOT iPaaS, MPaaS nor APaaS

Code

Push and Build

Deploy & Run

Monitor & Bug Discovery

Fix the bug

Update & Build

Gradually Redeploy

Scale Horizontally & Vertically

Enjoy automation

PaaS. What else?

Heroku-like PaaS

Heroku-like PaaS

• Buildpacks• Containers• Application vs Service• 12-factor applications• Multi-cloud/Specific Cloud

Buildpack magic

bin/detect bin/compile

• Installing plugins• Building artifacts• Caching artifacts

• Config_vars PATH: "bin:/usr/bin:/bin"

Container Creation Process

Application vs Service

The Twelve-Factor App (1)I. CodebaseOne codebase tracked in revision control, many deploys

II. DependenciesExplicitly declare and isolate dependencies

Dependency Library

V1 V2 V3

Codebase Codebase Codebase

Packaging System

IV. ConfigStore config in the environment

- File- Environment variables

III. Backing ServicesTreat backing services as attached resources

The Twelve-Factor App (2)V. Build, release, runStrictly separate build, release and run stages

VI. ProcessesExecute the app as one or more stateless processes

- Fully stateless- Share-nothing

VII. Port bindingExport services via port binding

• The twelve-factor app is completely self-contained

• There is no runtime injection of a webserver into the execution environment

VIII. ConcurrencyScale out via the process model

Share-nothing, horizontally partitionable nature of twelve-factor app processes

The Twelve-Factor App (3)X. Dev/prod parityKeep development, staging, and production as similar as possible

- Minimize the time gap: a developer may write code and have it deployed hours or even just minutes later

- Minimize the personnel gap: developers who wrote code are closely involved in deploying it managing it in production

- Minimize the tools gap: keep development and production as similar as possible

XI. LogsTreat logs as event streams

• Each running process writes its event stream, unbuffered, to

• Use log routers and log aggregators• Build alert system according to user-

defined heuristics

XII. Admin processesRun admin/management tasks as one-off processes

• Running database migrations• Running one-time scripts committed into

the app’s repo

IX. DisposabilityMaximize robustness with fast startup and graceful shutdown

- Processes should strive to minimize startup time

- Processes shut down gracefully when they receive a SIGTERM signal from the process manager

- Handle unexpected, non-graceful terminations (crash-based design)

Blueprint-like PaaS

Blueprint-based PaaS

• No code-to-binary step• Multi-layered• Legacy application support• Service discovery• VMs and/or Containers• Rich life-cycle management

Blueprint Standards

• OASIS TOSCA (Physical Host + VMs + Containers)

• Murano PL (VMs + Containers)• Virtuozzo Application Packaging Standard

(Containers/VMs)• Jelastic Packaging Standard (Containers)• Kubernetes/Swarm/Marathon (Containers)• HashiCorp Configuration Language• (Containers)• …

OASIS TOSCA
