Cloud-Native Platform Characteristics

5

Why do you Cloud?

• Obtain the right tool bits

– Access a pre-built platform

– Rely on embedded compliance, governance, and security

policies

• Creative experimentation

– Spin up and down on demand

– Lower startup cost

• Meet business demand

– Fulfill dynamic and spiky usage requirements

– Optimize spend

6

Why do you PaaS?

• Ready to DevOps

– Hug a virtual server (or container)

– Configure a run-time environment

– Provision software development lifecycle repos and tools

• Build better software and accelerate software delivery

– Offer a pre-built platform to development teams

– No QoS worries

Technical Objectives

• Improve efficiency and productivity

– Use Amazon EC2 or private Cloud

– Create small, scale-out containers

– Adopt DevOps practices

• Build New Style Systems

– Tap into shared middleware services

– Incorporate anti-fragile, circuit breaker design patterns

– Realize multi-tenancy and service-oriented solution design

Architecture

• SUSE Studio

• WSO2 Application Server

• Asset Repository

• User Store

• Amazon EC2

DevOps Steps

• Build container image with platform services

• Deploy the image into the Cloud

• Configure user store, security, and asset delivery

• Provision applications, services, and APIs

• Monitor and manage runtime environment

11*

Step 1a: Choose Container Services

12

Step 1b: Build the AMI

• Build the Image with SUSE Studio

– Start

– Software

– Configuration

– Files

– Build

13

Step 2: Deploy the Image into the Cloud

• Deploy Image on EC2

– Choose AMI size

– Ports

– Security key pairs

• Considerations

– Clustering

– System Dependencies

14

Build and Deploy Best Practices

• Automate build

– Pull resources from online repositories

– Define configuration as parameters

• Dynamically connect (and re-connect)

– Decouple location

– Inject circuit breakers

15

Step 3a: Configure User Store and Security

• Where is the user store?

– Internal user store

– External user store

• Access control

– Role

– Permissions

16

Step 3b: Configure Asset Delivery

• Deployment Synchronization

– Automatic hot-update to cluster

– Reconcile with version control

– Link to continuous delivery processes

17

Step 4a: Migrate Applications

WSO2 Application Server – Web Profile Support

18

Step 4b: Migrate Everything

19

Step 5: Monitor and Manage Run-time Environment

• Monitor

– Log file collection

– Run-time usage and performance statistics

• Manage

– Cloud node restart

– Resiliency

20

Bonus Step: Create a SaaS Application

• Multi-tenancy Considerations

– Tenant density model

– User Store

– Roles and Permissions

– Session cache

– Queues
