1. What is Fit2Cloud?

1.1 Introduction

Fit2Cloud is an Event­Driven Programmable Cloud DevOps Platform for AWS. This platform aims tohelp organizations to continuous deliver complex Cloud­Native App ontop of AWS Infra. It enablesdevelopers & Ops to achieve full­stack automation by writing event handlers.

It is very convenient, helpful, friendly for Developer, QA, Operator to install Apps and Services to virtualmachines in cloud and then run it and manage it, automates the monitoring, fail over, repair and scale,especially for the app that is large scale, distributed and complicated composed of lots of components anddeployed in lots of VMs.

1.2 How It Works?

Fit2Cloud manges system by cluster, group VMs to a cluster, when VM is launched by AWS:

1) EventAgent will be installed in each VM in the cluster.

EventAgent is a backend service that installed and running in each VM managed by Fit2Cloud upon theVM is launched by Cloud Provider such as AWS, then Fit2Cloud manages the runtimes and componentsof all the VMs by EventAgent.

2) For each VM, the VM’s BehaviorEvent initialize, install, start and StatusEvent such as beforeInitialize,afterInitialize, beforeInstall, afterInstall will be fired to EventAgent@Each VM in the cluster in sequence by aStateMachine after the VM is up in AWS.

The sequence is below:

beforeInitialize ­> initialize ­> afterInitialize­> preInstall ­> install ­> afterInstall­> preStart ­> start ­> postStart

3) When EventAgent@VM receive the Self’s BehaviorEvent, it will execute BehaviorEvent’s handler toinitialize, install and start component in the VM.

4) If there are a VM#1 listening on a EventVM#2 ’s StatusEvent, such as beforeInitialize, afterInitialize,beforeInstall, afterInstall, then StateEngine will fires the EventVM#2’s event to EventAgent@VM#1, thenEventAgent@VM#1 execute the corresponding listening event handler.

For example:

3

There is a wordpress cluster, there are two VMs, One is MySQL Role VM, the other is Wordpress­webRole VM.

We write 2 Event Handlers:1. MySQL’s BehaviorEvent install’s EventHandler

2. MySQL’s StatusEvent postInstall’s Wordpress­web EventHandlerWhen MySQL’s StatusEvent postInstall fires, the listening Wordpress­web EventHandler will be executedon Wordpress­web VMs.

Work Flow:1) MySQL Role VM launched

2) MySQL VM BehaviorEvents will happen in sequence ready ­> initialize ­> install ­> start

3) When MySQL VM install BehaviorEvent happens, eventAgent@MySQL VM will execute theinitialize BehaviorEvent’s eventhandler, the eventhandler will install and start mysql on the VM.

4) After 3), MySQL VM’s StatusEvent postInstall will happen, as MySQL’s StatusEvent postInstall’sWordpress­web Handler listening on the MySQL VM’s StatusEvent postInstall, the Wordpress­webHandler will be executed by EvnetAgent@Wordpress­web, the Wordpress­web Handler will get themysql’s IP and configure it to Wordpress­web’s db config file and restart.

5) Then Wordpress service is up in the Cluster.

Take Install Wordpress to a group of vms for example:

1. Create WordpressDev Cluster2. Add Wordpress­mysql Cluster Role and Wordpress­web Cluster Role3. Write Wordpress­mysql VM Role’s Events’ EventHandlers4. Write Wordpress­web VM Role’s Events’ EventHandlers5. Launch WordpressDev Cluster6. Verify Installation by Accessing the Wordpress Web

After Wordpress­mysql VM#1 up, EventAgent on the VM#1 will execute the Install Event’s EventHandler toinstall mysql on the VM.

1.3 Concepts

1.3.1 What is Environment?

Environment is a group of Clusters, All clusters in a Environment, share the same IaaS credential, use thesame IaaS account’s creating resources in IaaS Cloud Provider, such as AWS.

you can name the environment by your cluster types, such as you can name such as the Project, by TeamGroup, by usage or by region etc, for example:

Create environment CrazyBird_Demo_Env for demo project CrazyBird.Create environment Wordpress_Demo_Env for demo project Wordpress.Create environment CrazyBird_DevTeam_Env for dev team use.Create environment CrazyBird_CommonServiceTeam_Env for common service team use.Create environment CrazyBird_QA_Env for QA team use.Create environment CrazyBird_Steven_Env for team member Steven’s self dev use.Create environment CrazyBird_AWS_US_Env for group the clusters in USCreate environment CrazyBird_AWS_BJ_Env for group the clusters in BJCreate environment CrazyBird_AWS_Env for group the clusters in AWSCreate environment CrazyBird_CLOUDSTACK_Env for group the clusters in AWS

1.3.2 What is Cluster?

Cluster :

5

is a group of VMs, it belongs to an Environement, the VMs are all belongs to cloud account registed inEnvironment, all the VMs’ Bill are paid by the cloud account registed in Environment.

Example 1:

We want to run a wordpress for publishing self blogs, we can create a WordpressSelfBlog Cluster first,we put 3 VMs in, 1 nginx VM, 1 Web VM, 1 MySQL VM, then deploy Nginx, Web, MySQL to each VM.

Example 2:We are developing an app CrazyBird, we require 4 Envs for development, QA, Staging, production use.Then we can create a Dev CrazyBird Cluster for development use, create a QA CrazyBird Cluster for QAuse, create a Staging CrazyBird Cluster for staing use, create a production CrazyBird Cluster forproduction use.

In different cluster, it has differnt scale vms, such as1) for Dev Cluster, has 3 VMs2) for QA Cluster has 5 VMs3) for Staging Cluster has 10 VMs4) for Production Cluster has 100 VMs.

1.3.3 What is Cluster Type?

Cluster Type :

is a Cluster’s Type, it is composed of VM Roles, a physical divsion of a Cluster, you can think it asCluster Template, as VM Role is VM Template.

For example, for a Wordpress cluster, it will have 3 different type VM, MySQL, Web and Nginx.Then we define a WordpressClusterType, it contains 3 VM Roles1) MySQL VM Role2) Web VM Role3) Nginx VM Role

Each wordpress cluster is an instance of Cluster’s Type.

1.3.4 What is VM Role?

VM Role is a VM’s Type, it defined by its Behaviors when VM’s BehaviorEvent fires to the VM.

such as1) if a VM going to use as MySQL type server, when the VM BehaviorEvent install happens, it will beinstalled with MySQL, then the VM’s Role is MySQL VM Role.2) If a VM going to use as Webconsole server, install with Wordpress build, then the VM’s Role isWordpress­web VM Role.3) If a VM going to be deployed with all Wordpress required MySQL, Wordpress build, then the VM’s Role isWordpress­AllInOne VM Role.

6

This VM Role is defined by this Role’s VM’s behaviors after launched, we define Role’s VM’s behaviors bywriting event handler of the VM Role’s BehaviorEvent, such as for a VM, after launched and up,StateMachine will fire initialize, install, start BehaviorEvent in sequence, we can define when install event,install a component, for exmaple:

When Wordpress­web VM receive initialize BehaviorEvent, we execute the initialize’s EventHandler, theEventHandler will install the runtimes required, such as php, php­mysql, wget, then VM receive installBehaviorEvent, then install’s EventHandler will download the wordpress build and deploy the build to/var/www/wordpress, then VM receive start BehaviorEvent, the start’s EventHandler will start the web.

We can write the EventHandlers in Fit2Cloud Web to define the VM’s behaviors upon each status.

1.3.5 What is Cluster Role?

After a VM Role added to a Cluster, a Cluster Role is created, in Cluster role, you can control how many therole vms to launch and EBS mount and auto scalr settings.

1.3.6 What is Internal EventHandler?

Internal EventHandler is executed inside EventVM when EventVM receives BehaviorEvent,

In another word, an VM’s Event’s Internal Event Handler is to be executed only in this VM when VM’s eventfires.

VM’s BehaviorEvents includes initialize, install, start, reboot, postReboot, upgrade, backup, checkHealth.

For example, in a wordpress cluster, it includes 2 VMs, 1 wordpress­mysql vm, 1 wordpress­web vm, wedefines an install EventHandler for wordpress­mysql server role’s install event, then whenwordpress­mysql’s install event fires, the install EventHandler will be and only be executed on thewordpress­mysql VM, it will not be executed in wordpress­web VM.

We can implement auto deploy, configure, start a component on a wordpress­mysql VM role’s VM bydefining install event handler of Wordpress­mysql VM role.

1.3.7 What is External EventHandler?

External EventHandler is executed outside EventVM in other external VMs when External VM receivesEventVM’s StatusEvent.

In another word, an VM’s Event’s External Event Handler is to be executed in other VMs outside this VMwhen this VM’s event fires.

After the VM launched, the VM Status became to RUNNING, Fit2Cloud Status became topostStartResponse

7. Validate Wordpress Cluster

7.1 Validate MySQL is running in wordpress­mysql Cluster Role’s VMAfter MySQL VM Role vm launched, you can logon to the server by SSH Console Web.

Logon to the VM to verify the mysql is install and started successfully.

24

8. Create Wordpress­web Cluster Role in Cluster

Note:

If the Wordpress­web VM role already created, then Step 1 is not needed.

This case happens after you already create 1 cluster, when you create the second cluster, you do notneed to create the Wordpress­web VM role.

Step 1 : Create Wordpress­web VM Role1) Go to “VM Roles”2) Add Wordpress­web VM Role

Fill in Name (wordpress­web) Cluster Type (Wordpress­Cluster) Image Group (Amazon_linux_64_201309) Save

28

Save and can see below

8. Launch Wordpress Cluster

1) Go to “Clusters” ­> Select WordpressDevToyko1 ­> Launch

29

After request Launch, can see the Status of WordpressDevToyko1 status change to RNNING

Then, after a while, VMs of WordpressDevToyko1 because 2 VMs, then select “2 VMs”

Then, can see 2 VMs, and their info such as IP address, we can see that wordpress­web cluster role VM’sIP is 54.199.68.94

30

9. Register DNS

You can register it to your DNS Server orcall DNS API to register in Wordpress­web VM Role’s install event handler

Here, we simply implement this by register it to /etc/hosts

echo “54.199.68.94 wordpress.fit2cloud.net” > /etc/hosts

wordpress.fit2cloud.net is set in Wordpress­web VM Role’s install event handler.

10. Open 80 Port of Wordpress­web VM

1) Go to “VM Roles” ­> Select wordpress­web ­> “Actions” ­> Security Rules

2) Click “Add” ­> Fill in port info ­> Save

As currently we did not register the DNS yet, so we temporarily change local PC’s /etc/hosts to make it.echo “54.199.68.94 wordpress.fit2cloud.net” >> /etc/hosts

11. Verify Wordpress ServiceIn web browser, open http://wordpress.fit2cloud.net
