Amazon CloudFormations and Oracle Virtual Assembly Builder

Yesterday I blogged about AWS AMIs and Oracle VM templates. These are great mechanisms to stand up an initial cloud environment. However, they don't provide the capability to manage, provision and update an environment once it is up and running. This is where AWS Cloud Formations and Oracle Virtual Assembly Builder comes into play. In a way, these tools/frameworks pick up where AMIs and VM templates leave off.
Once again, there a similar offers from AWS and Oracle that compliant and also overlap with each other. Let's start by looking at the definitions:
AWS CloudFormation gives developers and systems administrators an easy way to create and manage a collection of related AWS resources, provisioning and updating them in an orderly and predictable fashion.

Oracle Virtual Assembly Builder - Oracle Virtual Assembly Builder makes it possible for administrators to quickly configure and provision entire multi-tier enterprise applications onto virtualized and cloud environments.

As with the discussion around should you use AMI or VM Templates, there are pros and cons to each:
1. CloudFormation is JSON, Assembly Builder is GUI and CLI
2. VM Templates can be used in any private or public cloud environment. Of course, CloudFormations is tied to AWS public cloud

Cloud Migration Lifecycle - Step 2 of 5

After setting up the PaaS and IaaS environments, the application owners can take advantage of the PaaS and shared component to more quickly assemble the applications and deploy it through a self-service mechanism. If their role entitles them to make the request, it is automatically provisioned. If not, it gets routed to their management and/or IT for workflow approval (just like a procurement process). The assembly of the applications can be done using the Oracle Virtual Assembly Builder. Oracle Virtual Assembly Builder is used to quickly create and configure end-to-end multi-tier applications and provision them onto virtualized resources. For example, a web server, application server, and database can be package into self-contained assembly and deployed to the Oracle cloud using a seb-based self-provisioning application. The other component of the applications is a central repository for all application assemblies. This central repository can take the form of an "iTunes-like" web accessible location for enterprise applications.

Cloud Migration Lifecycle

The first step in migrating to the cloud is the set up phase. This phase includes: 1. Plan Cloud Setup - Create a project plan. 2. Set up infrastructure - The IaaS and PaaS environments need to be installed and configured. This includes databases, network, hardware, disk and application servers. 3. Set up shared components - Are applications, database objects or other components going to be made accessible in the cloud ? These shared components need to be configured and made accessible. 4. Set up self-service portal - Customer self service provisioning, management and monitoring.
