Doing nothing is always the best option when acceptable. So optionally if an existing technology is a good candidate to be an ISA part and that it meets all the requirements above, then it should be retained.
This post is also the opportunity to initiate the building process of ISA.
(02 – Wishes)
The wishes, the requirements that an Ideal Software Architecture should have, in order to legitimately claim to this qualification.
ISA should offer a basic common management for specification, design, test, delivery and the like.
The purpose of ISA is to provide a common set of blocks on which any people involved in software can rely at anytime and anywhere.
Another aspect ISA should address is the continuity in the problem/solution chain thru specification/realisation and the abstraction levels.
Think and design ISA to be durable for several decades. The main design patterns should be incorporated as much as possible. This architecture should not limit itself in changes that it can elaborate to have good performances. And this in both dimensions hardware and software. Remain native : It is the condition to do at best of the possible. Define a solid base and then incorporate an extension mechanism.
Continue reading ISA Wish N°6 – Modern, performant and durableOne of firsts motivation of ISA is to unify the architecture and to make it simple in order to eliminate useless “expertise”.
ISA makes a break with the existent. Thus this architecture is free to make its choices. In other words, compatibility with actual IT is not a concern for ISA. This primary option eliminates the niches for geeks and experts.
Statics and dynamics have pros and cons :
➽ Static often offers the efficiency, an easiest use and the robustness.
➽ Dynamics offers simplicity and flexibility.
An ideal architecture shouldn’t have to choose. It has to incorporate gracefully both statics and dynamics in an unified world.
The first benefit to incorporate security in the lowest layers of ISA is that its safety is generalized every where ISA is deployed, and at anytime. This is a very important advantage when comparing to security problems recurrently occuring on all runtime environments (operating systems, browsers, etc.)

Distributed computing and storage have to be at the heart of ISA in order to adhere to the reality.
An other aspect of distribution paradigm, implies that the data and treatments are scaling horizontally. Taking advantage of all 4 dimensions of our universe.
An old dream to begin, connect a computing unit as easily as we connect any device, like a washing machine or a telephone, and it is ready to run. In other words, all the needed things are either embedded or come from the connections.
Continue reading ISA Wish N°1 – Plug and play generalizedHaving defined the scope of the Ideal Software Architecture (ISA), it’s time first to make a list to Santa Claus of what will be nice to have in computer science. Wish N°1 – Plug and play generalized. An old dream to begin, connect a computing unit as easily as we connect any device, like a …
