Architecture selection
There lies great complexity when it comes to choosing between underlying hardware and software arrangements and their potential architectures. With these there usually is a trade-off and high-quality visuals that end up consuming a whole lot of time or even end up using very low-quality visuals that cannot be completed easily. The whole idea behind architectural selection is to ensure that architect shouldn’t be in apposition to choose between quality and efficiency but maintain the two at a constantly low cost.
There are several factors that should be considered when choosing the best architecture to use. These include:
Pricing involved
Tweak materials directly in your renderer or engine
Renderer and engine ready
Multiple resolutions
Ending up with the perfect architecture is always key and the best for any firm that is practicing distributed systems architecture. The four most important are:
1. Architecture styles
Layered architecture is usually used for client-server system
Object based architecture is for object systems. These may be less structured where component is equivalent to object.
Data-centered architecture
Event-based architecture
The advantage of this architecture method is that all the styles are loosely coupled to each other and therefore do not need explicitly when referring to each other. An event can be defined as a momentous change in state.
Centralized architecture
In this form of architecture, the many processes offering services to both servers and clients can be placed on different machines that follow and allow for the reply model when using servers.
Decentralized architecture
Over the last few years, there has been a tremendous growth in peer-to-peer systems. These can be either structured, unstructured or hybrisDP2P. In most cases when dealing with overlay networks data are routed over connections setup between the nodes and the application-level multicasting. The nodes formed by the processes of the network are an example of overlay network.
The most appropriate architecture that is very appropriate for this distribution system based on the results of the analysis carried out earlier is decentralized architecture. With the peer-to –peer concept it is easy to organize all the nodes in a well -structured overlay network such as a logical ring, and make specific nodes.
All nodes act as both client and server, and ensure interaction is symmetric always.
Each node acts as a sever for part of the total system data
Each node can address their own system for storage and retrieving of data in the system hen required.
Nodes can also route requests to locations that may not be known by the requester or the user of the server.
With a common approach to the use of a distributed hash table (DGT) that can organize the nodes in more traditional hash functions that convert a key to a hash value and can be used as an index into a hash table. With the application and use of unstructured PP systems, there is mainly the reliance of randomized algorithms for the construction of an overly network. However, depending on the exchange of the network can be maintained easily with this kind of architecture.
This selection of architecture is best for the following reasons:
1. The pricing is relatively cheap compared to other architectural methods.
The materials featured are made readily available through substance source. They are also accessible in many for and provide for premiums that the architect is comfortable to work with. The combination and use of the servers and client nodes together also reduce the prices of the required materials.
2. Qualified personnel with high talent levels
There is high reputation for a firm matter and with the decentralized architecture they can understand the team working on the upcoming project.
3. Ability to streamline work of the components
When building a relationship with a firm they must be the long-term visions and short-term project goals. If the decentralized architecture can meet these goals then this is the best option of a firm to use for the upcoming project. The location of the firm is also a key factor is issuing of the tender to an architectural firm. Working remotely and virtually with a building firm has become easier over the years making it easier to choose the best company to go with.
In conclusion, it should be noted that when it comes to searching for, deciding and hiring an architectural, engineering or construction for a project involves many levels of decision making, resourcing and considerable time. The need to use an integrated design build firm comes with many advantages when choosing the right firm to work with. It should also be noted that choosing a different company for each component could result to addition of the work and thereafter increasing the total cost that could have been used. Regardless of whether you hire an integrated firm for all the project components all the factors discussed above that influence the choice of the architectural company should be put into consideration.
