Adoption of Design Tracker by users and projects
DesignSet into Synthetic Request without speaking directly to the
synthetic chemists fi rst. This allows chemists to order reagents and
develop the route without having to repeat the process when more
compounds were added. The synthetic team leaders and chemists can,
therefore, have an understanding of the relative worth of each designset
and assign resource appropriately.
12.4 Infrastructure
Now we discuss the infrastructure required to deliver this. Our production
server is a single server, which cannot provide a robust solution, it was
clear we needed multiple servers. In addition other computing design
principles became apparent. For example the database should run on
different hardware to the application layer. Within the database layer
read and write operations should be restricted to distinct MySQL
instances to improve performance. In the application layer dynamic and
static requests should be separated. Additionally hardware should be
redundant. Software must manage high-availability, loads, failover and
all seamlessly work together. This is not new: Wikipedia, Facebook
and Google all have similar infrastructures to deliver the most accessed
web sites in the world using a similar software stack to us.
