DBaaS
Platform as a Service (PaaS) is a way to rent hardware, operating
systems, storage and network capacity over the Internet. The service
delivery model allows the customer to rent virtualized servers and
associated services for running existing applications or developing
and testing new ones.

Cloud is reliable when it comes to the point “Deployment”. Many high-
end infrastructure companies serve a great deal of services.
Two such services that developers get for their easier development and
deployment are Compute Ecosystem and DBaaS.
We shall dive more into it further.*
* A basic and overall knowledge of the platform shall be discussed, rather than diving deep.

PaaS Platform-As-A-Service
 Sounds a bit like “Techhnologyyyy”
 A category of #Cloud computing services
 Provides a computing platform and a solution stack as
a service
 Software as a Service (SaaS) and Infrastructure as a
Service (IaaS) in the model
 Host client application
 Provides controls software deployment and
configuration settings
Database Service Storage Service
Develop & Deploy

Services
Cloud SQL
Cloud Filesystem
Cloud IDE
Cloud NoSQL
Cloud Servers
Cloud Monitoring
What you GET ?

Act upon!
You are
Why ?
 Convention over configuration
 Concentrate only on product development
 Less
 In time completion
 Fear not ! Your project is hosted on high-end
servers
 Doesn’t leave a ‘HOLE in your pocket’
 Better networking (if considered cost effectiveness)
 Monitor your app on a cup of coffee

Diving deep *
o Basic knowledge on dynamic web
programming
o Concurrency & threads
o Database Management System
o Java Programming
Perquisites

Life Cycle
Client
{ Browser | Mobile Application | Desktop Application }
PaaS Platform
Internet
Application Servers
Filesystem
Platform Services Layer
Database Servers

Platform Ideas & Components
Access Layer
o General access through Internet via HTTP
o Make use of HTTP protocol attributes(cache,
stateless)
o SSH protocol for remote shell access
o FTP servers extends the platform’s functionality
for easy file synchronization, using FTP protocol
Concurrency & Communication
o Threads aren’t available everywhere
o Asynchronism via provider dependent APIs.
o Usage of messaging infrastructure

Runtime Environment
o Based on existing runtime environments
o Can be shut down at anytime by PaaS provider
o Partially limited (sandbox)
o Manages database access
Persistence
o No direct disk access
o Hold data on DB, caches or BLOB stores
o Access via provider dependent API or runtime
environment
o Redundant storage

Development Process
o Provider selection (vendor lock-in)
o SDKs and IDE plugins provided
o New development or migration
Programming Model
o Comparable to EE application development
(cluster of application servers with load
balancers)
o Asynchronous

A look at the
Service Providers
Google Microsoft Oracle Amazon Heroku

Google Cloud Platform

Google App Engine
o Language choice
o SDKs
o Platform Tools
o Integration with Google Data Store,
Google Drive or other services
o Compute engine as the execution
ecosystem
Google Data Store
o SQL and NoSQL support
o MySQL as the SQL Database
o Web interface for easy setup and
management
o Great APIs
o Fully managed instances
Google Cloud Storage
o Google Drive
o Filesystem based
o Access control using authentication
o Subscription based

 Similar functionality as in DBMS
 Provide flexible, scalable ,on-demand platform
 No need for application developer to know be database expert
 No need to hire DBA
DBaaS Database-As-A-Service
Database Management System

Flexible
 Variety of preinstalled or preconfigured database
 Resources are elastic
 Easy migration
 Provision a complex database cloud
service in few minutes
 Get started immediately
FAST
Why

Subscription-based
 Choose a simple hourly, monthly or yearly
subscription
 Modify your subscription package as per
requirements
 Server Software
 Database versions
 Database options
 Access methods
Choice
 With few clicks build a complete
Database environment
SIMPLE
Setup
Example of Cloud Database DSN
postgres://awjvlgstnvypar:L9CrrRrPJ5PN2esrtmuoWTTMu8@ec2-54-
235-146-58.compute-1.amazonaws.com:5432/d31l86dqllkqvi

Security
 Account Security :Identity Domains (user pools)
 User Security : Authentication via user login
 Database Security :Schema user for security (user access),data security
 SSH Tunnelling :Generate and store
 Private /public key pair on local PC;
 Create database instance in a VM, using the public key stored on the
cloud server.

Administer
• Full OS root and SYS database access
• Administration control of your VM and your
database via SSH,SQL Developer , Data
pump and other tools
 Fully manage your database or have Oracle
manage standard database operations, such as
backup, patching, and upgrade.
Manage
 Monitor your database
