INSTALLING GOOGLE APP ENGINE
Date:

AIM:
To implement on PaaS to Install Google App Engine, create a program to validate
User and create a database login in mysql and deploy to cloud.

PROCEDURE:
Before we proceed with the installation process follow the steps.
 Create a Compute Engine instance
 Install MySQL
 Connect to MySQL

To create a Compute Engine instance in the Google Cloud console:

1. Open the Google Cloud console.
2. Select your newly created project and click Continue.
3. Click Create instance
4. Name the instance mysql-test.
5. In the Public images tab, select an operating system and then click Save.
6. Click Create.

Set up a Cloud SQL instance

 Enable the Cloud SQL Admin API in the project .
 Create a Cloud SQL for MySQL instance.
 By default, Cloud SQL assigns a public IP address to a new instance. We also have the
option to assign a private IP address.

Create a Cloud SQL Second Generation instance.

We can set the password for the default user on your Cloud SQL instance:

gcloud sql users set-password root --host=% --instance [INSTANCE_NAME] --password[PASSWORD]

Record the connection name for the instance:

gcloud sql instances describe [INSTANCE_NAME]

4 PANIMALAR POLYTECHNIC COLLEGE

 CLOUD COMPUTING AND INTERNET OF THINGS PRACTICAL

Create a database on your Cloud SQL instance.

gcloud sql databases create [DATABASE_NAME] --instance=[INSTANCE_NAME]

Setting up your local environment

Authenticate the gcloud tool to use the proxy to connect from your local machine:

gcloud auth application-default login

Setting connection strings and adding a library
Set up the local environment to support connections for local testing. For example, for the
provided code sample:

export MYSQL_DSN="mysql:host=127.0.0.1;port=3306;dbname=DATABASE;"
export MYSQL_USER=USER
export MYSQL_PASSWORD=PASSWORD

To allow your app to connect to your Cloud SQL instance when the app is deployed, add the
user, password, database, and instance connection name variables from Cloud SQL to the related
environment variables in the app.yaml file:

env_variables:
# Replace USER, PASSWORD, DATABASE, and CONNECTION_NAME with the
# values obtained when configuring your Cloud SQL instance.
CLOUDSQL_USER:
CLOUDSQL_PASSWORD:
CLOUDSQL_DSN: "mysql:dbname=DATABASE;unix_socket=/cloudsql/CONNECTION_NAME"

OUTPUT:

RESULT:
Thus, we have installed Google App Engine to implement PaaS.

INSTALLING VIRTUAL BOX
Date:

AIM:
To install Virtual Box on Windows operating System.

PROCEDURE:
 Open Virtual Box download page, scroll down and find the latest version
 Click on the latest version number.
 Scroll down, find the .exe file, and download it
 Once VirtualBox Windows installer is downloaded, run the executable file.
 Follow through onscreen instructions to install VirtualBox on Windows.

 VirtualBox installs virtual network adapters and therefore we may lose network connectivity temporarily
during installation.
 After VirtualBox installation finishes we will have to restart your computer.
 After reboot, VirtualBox should be available in your apps as shown below.
 We can now run VirtualBox and create Windows virtual machine with almost any OS.

The steps required to install OpenStack are as follows:

 Install Virtual Box or Create Virtual Machine.
Download the Oracle virtual box and create the VM machine with a specific configuration of 64 bit
OS with 8GB RAM and 300 GB of memory.
After creating the VM for a specific OS required, open the terminal and disable the firewall.
 Download the OpenStack version.
Use the below command to download the OpenStack version through the terminal. The command
is ‘yum install –y centos-release-OpenStack-newton.’
 Update the packages.
Use the below command to update the package.
The command is ‘yum update –y’.
 Use the tool to install OpenStack.
The command is ‘yum install –y OpenStack-packstack’.
 Installing services.
The below command is used to install all the services or components for OpenStack. The command
is ‘packstack –allinone’.
It will install everything and installation complete for OpenStack.

CASE STUDY
Date:

AIM:
Case study on open source and commercial cloud.

THEORY:

Amazon Web Services (AWS) and Microsoft Azure are the two giants in the world of cloud
computing.

While AWS is the largest cloud computing platform, Microsoft Azure is the fastest-growing
and second-largest.

Azure is a cloud computing platform and an online portal that allows you to access and
manage cloud services and resources provided by Microsoft. These services and resources include
storing your data and transforming it, depending on your requirements. To get access to these
resources and services, all you need to have is an active internet connection and the ability to
connect to the Azure portal.

Azure provides more than 200 services, are divided into 18 categories. These categories
include computing, networking, storage, IoT, migration, mobile, analytics, containers, artificial
intelligence, and other machine learning, integration, management tools, developer tools, security,
databases, DevOps, media identity, and web services.

Amazon Elastic Compute Cloud (Amazon EC2) provides scalable computing capacity in the
Amazon Web Services (AWS) Cloud. Using Amazon EC2 eliminates your need to invest in hardware
up front, so you can develop and deploy applications faster. You can use Amazon EC2 to launch as
many or as few virtual servers as you need, configure security and networking, and manage
storage. Amazon EC2 enables you to scale up or down to handle changes in requirements or spikes
in popularity, reducing your need to forecast traffic.
