Amazon Public Cloud Design Pattern: Template

Objective: To provide ready to use environment.

Application of Cloud: Applications need environment to run. It requires web server / application server / database server normally. To install all software and make it available to deploy an application successfully takes lot of time in either virtual or physical environment.

The benefit of Cloud / Virtual environment is that, you can create a template in which OS, application server, application etc. are already installed and from that you can create new instances within minutes and you need not to install everything every time it fails. Do it properly once and use it to create similar kind of virtual machine in future. User needs to create baseline instance and from that new virtual machines can be created and it can be configured as per requirement. That is called template.

Implementation on AWS:

As we have seen in Amazon Public Cloud Design Pattern: Snapshots, EBS Disk which is Boot Disk, can be used to create multiple virtual machine with same settings. Launch an EC2 Instance and install all software you need to run application, configure that instance properly; Capture that Amazon Machine Image and use it to create multiple EC2 instances with similar settings.

FreeNAS 8.3 installation on Virtual IDE Hard Drive

NAS is a dedicated hardware device that connects to a LAN where file level computer data can be stored and retrieved across that network.

Open source NAS oriented distributions of Linux and FreeBSD are available such as FreeNAS, NAS4Free. CryptoNAS, NASLite, Gluster, Openfiler, and OpenMediaVault which can be installed in commodity hardware, connected and configured using web browser. Open source NAS implementation can run from virtual machine as well as USB disk; we will see both the cases in the coming section of FreeNAS installation.

FreeNAS is an advanced FreeBSD-based operating system for network-attached storage server having easy to use web UI. FreeNAS is distributed as an ISO image. It is released under a BSD license which imposes nominal limitations on the redistribution of covered software.

Create Virtual machine having 512 RAM, 20 GB Virtual HDD, 1 Processor created on Physical machine having Intel Pentium Dual CPU t2370 @ 1.73GHz, 2 GB RAM, 160 GB HDD and 32bit OS.

VMware workstation or VMware player can be used to create a virtual machine. Attach FreeNAS ISO downloaded from the sourceforge and start the virtual machine.
