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.

Forth Key attribute of Cloud Computing - Provisioning

Provisioning the system from end to end - OS, hardware, storage, application, network and datavase need to be self service provisioned. Provisioning is dynamic and self-service provisioning of applications involves deploying applications to your cloud infrastructure with a few mouse clicks. So, when moving to the cloud, application provisioning will be made easier since there are not hundreds or thousands of client machines to deploy too. Self-service provisioning of computing infrastructure in a cloud infrastructure is also very desirable as it can cut down the time it takes to deploy new infrastructure for a new application or scale up/down infrastructure for an existing application. Public cloud service providers like Savvis, Terremark, and AT&T all have self-service portals where users can sign up for cloud services and their compute infrastructure is ready within hours for usage. Oracle Enterprise Manager provides many Application Programming Interfaces (APIs) that can be incorporated into the self-service portals of cloud providers to automate the provisioning of compute infrastructure for Oracle products such as Oracle Fusion Middleware and Oracle database.

Cloud 2.0 migrations versus Cloud 1.0 migrations

In the early 1960s when companies started migrating to the Cloud 1.0 (mainframe-based cloud), existing computerized systems to migrate from did not exist. The manual systems, that sometimes the computerized application replaced, were rudimentary and easily replaced by a computer-based system. This made moving to Cloud 1.0 much easier than Cloud 2.0 migrations as you where implementing a new system clear of any legacy ‘baggage’. Today, companies are shackled with hundreds of business applications based upon mainframes, mid-range, and client/server systems deployed using mostly custom developed applications or Commercial Off-The-Self (COTS) products. Migrating existing IT systems to the Cloud 2.0 involves migrating everything from the data to the application, application deployment solutions or procedures, management and monitoring software, integration, data warehouse, business intelligence, replications solutions and backup and recovery, and perhaps even hardware infrastructure.
