A Step By Step Guide To Put DB2 On Amazon CloudPresentation Transcript
A step-by-step guide to put DB2 on EC2 Deepak Rao, IBM November 26, 2009
The IBM View of Cloud
“ Cloud” is an emerging consumption and delivery model for many services .
More employee mobility
Responsiveness and agility in delivering new solutions
Allows IT to Shift Focus
Hybrid infrastructure: public and private
What Cloud Computing means to DB2
Cloud Computing means a lot of different things to a lot of people:
Cloud datacenter (Utility Computing)
Data as a Service (DaaS)
Software as a Service (SaaS)
Platform as a Service (PaaS)
DB2 focus is on reducing IT costs by leveraging Utility Computing
What is Utility Computing?
Utility computing is the packaging of computing resources, such as computation and storage, as a metered service similar to a traditional public utility (such as electricity, water, natural gas, or telephone network). This system has the advantage of a low or no initial cost to acquire hardware; instead, computational resources are essentially rented.
The DB2 strategy for the Cloud
Deliver key technologies to support our customers’ private cloud initiatives
Partner with key public cloud providers to fully integrate DB2 in to the ecosystem
DB2 9.7 can now be purchased from IBM through CD/DVD’s or on Amazon as an AMI
Provide robust DBMS for SaaS vendors
Offer terms and conditions and pricing to make DB2 the best DBMS for the Cloud
DB2 options for AWS
Pre-built Development-Use DB2 AMIs
Based on DB2 Express-C (32, 64-bit options)
No DB2 usage fees – just pay for Amazon’s infrastructure
DB2 assistance through online forums
Pre-built Production-Use DB2 AMIs (2Q09)
For DB2 Express (32-bit) and Workgroup (64-bit)
Hourly usage fee includes DB2 license, OS subscription, EC2 charges
Can purchase optional DB2 support
Create your own DB2 AMI
Use your existing DB2 licenses
Get DB2 support from IBM as usual
Amazon Cloud Computing Key Concepts
Elastic Compute Cloud (EC2) : Is a web service provided by Amazon, it is a resizable & scalable compute capacity in the cloud, Run time environment. Five configurations starting at $0.10 per hour.
Simple Storage Service (S3) : Amazon Simple Storage Service (S3) is the distributed storage component of the AWS platform. It can read, write, and delete objects representing data ranging from 1 byte to 5 gigabytes. You can use S3 to store, replicate, and persist an unlimited amount of objects in the cloud. However, you should not think of S3 as a local disk and attempt to run your database from S3. Storage on demand. Pricing starts at $0.15c per GB/Month
Elastic Block Storage (EBS): Amazon Elastic Block Store (EBS) offers persistent storage for Amazon EC2 instances. Amazon EBS volumes provide off-instance storage that persists independently from the life of an instance. Amazon EBS volumes are highly available, highly reliable volumes that can be attached to a running Amazon EC2 instance and are exposed as standard block devices. Amazon EBS volumes offer greatly improved durability over local Amazon EC2 instance stores, as Amazon EBS volumes are automatically replicated on the backend (in a single Availability Zone). Can be attached to EC2 to allow persistent storage. Starts at $0.10 per GB/month
Amazon Machine Image (AMI): An Amazon Machine Image (AMI) is an encrypted machine image that contains all information necessary to boot instances of your software. For example, an AMI might contain Linux, Apache, and your web site or it might contain Linux, A virtual image containing OS + Software; It runs on Amazon EC2 Infrastructure, AMI’s are stored in Amazon S3.
Amazon Instance: An instance is the AWS version of a server. They come in a variety of sizes small, large, and extra-large and are designed to provide predictable and dedicated computing power on demand. Amazon charges you directly based on instance-per-hour usage.
EC2 API’s: Amazon Provides API’s which can be used in Perl, Python, Ruby or Java to write your own code to Develop, Deploy, Manage Cloud Infrastructure through programs.
SSH Key: When you launch an image through AWS, you will specify a particular SSH Key (*.pem) to associate with that image. This allows you to gain access to your machines without using passwords. This is the recommended (and more secure) way to access your instances.
Bundles: Its an Amazon way of providing a ‘build’ of different software which can be instantiated. IBM has several “Builds” for DB2 pre-built, ready to be initialized. Alternatively, You can make your own Builds.
Elastic IP: Elastic IP addresses are static IP addresses designed for dynamic cloud computing. An Elastic IP address is associated with your account not a particular instance, and you control that address until you choose to explicitly release it. Unlike traditional static IP addresses, however, Elastic IP addresses allow you to mask instance or Availability Zone failures by programmatically remapping your public IP addresses to any instance in your account.
Steps for setting up DB2 9.7 on Amazon Cloud Platform
You can setup DB2 on AWS 2 ways, GUI or EC2 API based scripts, However the steps involved are same. They are:-
Setup AWS/EC2 account (One time activity)
Download Security Certificates (One time activity)
Download Firefox UI (One time activity)
Update Personal & Payment information (One time activity)
Login to AWS
Choose a suitable AMI & launch an Instance
Login/SSH to the Instance & accept Product licensing
Setup Security & DB2 settings
Create Database, Test Connectivity to applications
After tests, don’t forget to shutdown AMI Instance to avoid charges to your Credit Card!!
Note: Amazon AWS Cloud computing can be setup 100% without manual intervention through API codes, but for the better understanding of components involved in Cloud Computing we will use the step-by-step method through GUI.
Sign up for a free AWS & EC2 account
Download certificates/Keys to a folder
Download Amazon AWS Plug-in for Firefox: http://developer.amazonwebservices.com/connect/entry.jspa?externalID=609
Setup your personal Information
Setup Payment information
Launch AWS Console
Create an Instance of pre-configured DB2 AMI
Select the Image for DB2 9.7
Launch the AMI Instance
Check the status of the Instance
Confirm the Instance is up & running
Firefox UI Amazon EC2
Launching Terminal for the newly created Instance
Storage (EBS) Configuration
Configuring Users on AWS
DB2 Instance start-up
Connecting to the Database
Shutting down the Server Instance
Yes, Amazon provides a whole lot of API’s which can be downloaded & used in your own programs to automate the steps seen till now.
