Cloud Computing is a computing service provisioning and delivery model in which users get access to dynamically scalable computing capacity over the network in a pay-as-you-use payment scheme.
While its attractiveness may differ depending on whom you've talked to, its service-oriented nature gives users two important benefits: ease of application deployment someone else's hard works laying down the hardware and software foundation and on-demand access anytime from anywhere. These characterstics make Cloud Computing ideally suited for developers who want to quickly try something out in an isolated "good" environment without the overhead of system setup or the capital expenses of paying for systems they no longer need after they are done.
In the past Teradata provided developers a Teradata Express Edition that runs on top of Windows bit platform. Like all programs with installers, it required that users first find a system, then go through the installation, deal with any unexpected setup problems, and finally uninstall and repurpose the system for something else.
Now, Teradata Express 12 for Amazon EC2 is set to change the paradigm and makes developers' life simpler and better. It has Teradata database The old Express Edition limitation with 4GB storage has now been expanded to 1TB, giving developers more freedom to experiment with larger datasets and with more real-life development and testing needs. If you are interested, this post will show you how to automatically setup Teradata Express 12 for Amazon EC2 using an automated script.
Note, this article assumes that you have some working knowledge of Amazon EC2 platform. Please note that while this product is not officially supported, you can talk to other users and get help in the Cloud Computing forum. There are two ways to connect to Amazon AMI instances. The installation procedures for it can be found here. The setup reference for it can be found here.
We will demonstrate the steps using either tools. After you set up Amazon EC2 API Tools, you can launch an instance by running the following command "ec2-run-instances ami-id -k gsg-keypair --instance-type m1. Replace ami-id with Teradata Express 12 for Amazon EC2 ami-id of amidec Note: the ami ID may change in the future so check your confirmation email instance-type m1.
Once the instance is launched, you can check the status of the launched instance: "ec2-describe-instances instance-id" by giving the id of the instance we just launched. Example: Click on Add b utton when credential information is entered and then click on Close button. Once logged in, click on " Images " tab and type into the textbox right below the "Images" tab Teradata Express 12 for Amazon EC2 ami-id , which is amidec Note: ID may change in the future so check your confirmation email.
Subsequently, in the pop-up Launch new Instance s window, select Instance Type if desired. Finally, click on Launch button at the bottom of the window.
Once your Teradata Express 12 for Amazon EC2 instance is launched, grant permission on port so that the database can be accessed from outside of the Amazon EC2 environment.
Finally, attach EBS volumes to your instance. In addition, a volume must be in the same availability zone as the instance that it will be attached to. After the volume is created, we can attach it to a running instance. A dialog box will appear and it allows you to select the Amazon EBS volume that was created earlier from the drop down box and a device name need to be entered in order to attach the volume.
Users with minimal knowledge can interact with Amazon EC2 using Elasticfox, but it is recommended to have basic understanding of web services. Amazon Elastic Compute Cloud is often referred to within this guide as quot;Amazon EC2quot; or simply quot;EC2quot;; likewise the Amazon Simple Storage Service is referred to in this guide as quot;Amazon S3quot;; all copyrights and legal protections still apply.
Amazon EC2 Elasticfox Version 1. The sections below walk you through how to install Mozilla Firefox, the web browser required to use Elasticfox, and the Elasticfox plug-in. To get Mozilla Firefox, please perform the following steps: 1. Save the file, and follow the installation steps on the acknowledgement page.
To do this, please perform the following steps: 1. Click on the download button. After the pop-up box comes up, press the install button. Your Mozilla Firefox browser will prompt you to restart your browser. After you have restarted, you will now have the ability to use Elasticfox. These are three different actions that must be performed separately.
If you don't already have an AWS account, you will be prompted to create one as part of the sign up process. If you already have an Amazon EC2 account, you can skip this step. To sign-up for Amazon EC2 simply perform the following steps: 1. This means you will also need to sign up for Amazon S3.
If you already have an Amazon S3 account, you can skip this step. Click the Sign up for this service button. Setting up Elasticfox The following steps are required to configure Elasticfox with your specific security credentials. These steps only need to be performed once, unless you change your security keys change again. Once you have configured these settings, you will be ready to proceed to the tutorials.
Access identifiers are also used to authenticate requests to AWS. The steps below show how to configure Elasticfox with your credentials, so that it can perform web service requests on your behalf. Enter your Account Name. You can set the Account Name to anything you want.
We recommend something meaningful like the email address you used when you created the account. To generate a keypair, simply perform the following steps: 1. Click on the green Key icon at the top of the tab. You will be prompted for a location to save the. Your KeyPair will now be created; remember this name, because you will use it later. This tutorial assumes that you have completed the necessary setup as described above. Core Concepts The sections below outline the core concepts used in this tutorial.
It contains all the information necessary to boot instances of your software. It is somewhat analogous to a snapshot of the boot partition containing the operating system and installed software running on your server. All instances launched from the same AMI will create a nearly identical running server except for the IP range or computer name. Note that an instance is ephemeral and that any information on it is lost when it is terminated or if it fails.
Security Group The security group is analogous to a firewall that can block all incoming ingress and outgoing egress traffic that does not come in on a specific IP specified by a CIDR or port number range. Each EC2 instance can be a member of up to security groups. Group membership cannot be changed while an instance is running, but the rules within the group can be changed, and will take effect immediately. Multiple security groups can be used to create secure, multi-tiered systems. For example, consider the classic three-tier model consisting of web, application, and database servers.
Placing each tier of servers in a distinct security group allows the web server to be accessible externally, with controlled access to the other tiers on an as —needed basis. Step 1: Setting up a Security Group Every launched instance requires that you have a security group defined to specify what network traffic is allowed to reach the instance.
By default we do not enable any traffic. If you have already defined a security group to allow network traffic from your address you can skip this step.
To open these ports for testing purposes, please complete the following steps: Amazon EC2 Elasticfox Version 1. The Group Name and Description fields are used to help you maintain and organize all of your security groups. Ensure the Security Group is now highlighted and click on the green checkmark in the Group Permissions box.
This will allow you to enable specific ports to receive network traffic. A new dialog box will appear.
