scalability

I am working on a large-scale software infrastructure in C++11 that makes extensive use of variadic templates. My question is the following: what is the scalability of this approach? First, is there an upper limit in the number of arguments that variadic templates can take? Second, is code bloat a major issue with state-of-the-art compilers when many arguments are used (and, by extension, many combinations of these arguments that would yield to many different implementations of the templated methods)? I thought I'd have a go at finding out whether there is any limit on the number of template

What are the problems, if any, of storing binary data in Riak? Does it effect the maintainability and performance of the clustering? What would the performance differences be between using Riak for this rather than a distributed file system? Elad Adding to @Oscar-Godson's excellent answer, you're likely to experience problems with values much larger than 50MBs. Bitcask is best suited for values that are up to a few KBs. If you're storing large values, you may want to consider alternative storage backends, such as innostore . I don't have experience with storing binary values, but we've a

I'm new to Azure architecture and am trying to understand why Azure Resource Groups, which are logical deployment buckets for applications built on Azure, are associated with a region when they are defined. At first I thought it was to provide global distribution for disaster recovery or geographic redundancy, but then I realized that a single Resource Group can contain web apps in different regions, which can provide those features via Traffic Manager. I suppose that using separate Resource Groups would help better identify which resources are in which region, but other than for
