Can anyone help me with a question about webservices and scalability? I have written a webservice as a facade into our document management system and need to think about scalability issues. What areas should I be looking at to ensure performance and availability?
Thanks in advance
Performance is separate from scalability. Scalability means that you can add more servers to linearly increase system throughput (i.e more client connections). The best way to start is having stateless webservices. That way any client can call any of the n webservice intance on n different machines. If there is a shared database at the end for persistence that will ultimately be your bottleneck. There are ways to reduce that with data partitioning and sharding, but only when you get to that point.
