Virtual Telecom Applications and an innovation architecture
I have been looking into virtualization but what I find are mainly operation system based virtualizations. What I am looking for are application, integration and datastore virtualization solutions. Google’s App Engine and Oracle’s JRocket Virtual come closed to what I am looking for application virtualization. Why do you need an operating system if you could virtualize your application directly? It would save resources and would be more secure. My ideal solution allows developers to write applications and run them on a virtual application server. This virtual app server can scale applications horizontally over multiple machines. Each application is running in a sandbox hence badly written or unsecure applications will run out of resources and are not able to impact other applications. We would need a similar solution for integration solutions. Both would need out of the box support for multi-tenancy in which either a tenant gets a separate instance or multiple tenants can share one instance if supported by the software. Integration should be separated from the application logic and so should data storage.
Integration is key because the virtual applications could be running on a public cloud but would have to be able to interact with on-site systems. Enormous high-throughput, security, multi-tenancy and resistance to failure are key. One API can be linked to multiple back-office systems or different versions. Different versions of an API can be link to the same back-office system to prepare applications before a major back-office upgrade.
A distributed multi-tenant data store should hold all the end-user and application data. Ideally in a schema-less manner that avoids having to migrate data for data schema changes.
All these virtual elements should be managed by an automated scaling and highly distributed administration that can let applications grow or shrink based on demand, assure integration links are always up and get re-established if they fail, store data in a limitless way, etc. But there is more. The administration should allow to deploy different versions of the same application or integration and allow for step-wise migration to new versions and fast roll-backs.
Why do we need all this?
The first company that will have such elements at its disposal will have enormous competitive advantages in delivering innovative services quickly. They can launch new applications quickly and scale them to millions of users in hours. They can integrate diverse sources and make them universally available to be re-used by multiple applications. They can store data without having an army of DBAs for every application. They can try out new features and quickly scale them up or kill them. In short they can innovate on a daily basis.
The Google’s of this world understood years ago that a good architecture is a very powerful competitive weapon. There is a valid trend to offshore technical work. However technical work should be separated in extremely high-value and routine. Never off-shore high-value work. Also never assume that because the resources are expensive, it must be high-value. Defining and implementing this innovation architecture is extremely high-value. Writing applications on top of it is routine at least starting from number 5.
