wcf - Facade Pattern for distributed application? -

-

We are in the process of defining a large client's structure while facing financial applications where performance and scalability are major requirements We have proposed an N-level architecture, which is the communication system between the web-level, apparatus tier (mid-tier) and data tier WCF's web-level and app level. Some stakeholders are worried that the WCF will cause performance and want to configure configurable architecture to support in-process calls and WCF. Their approach is to start with in-process calls and to convert it into WCF based communication if horizontal scalability is a concern.

We are considering the following methods:

  • An architectural approach will have to present a customer mask layer that forms a mask between web and app layers Can work in The excuse layer will easily hide the complexity of the remote call and allow easy swapping of the mask for each other, which could potentially implement a separate remote call technique (i.e. WCF)

    • < Li>

    There is another way to use WCF only and use different bindings for different situations. For example, use IPC binding when web and application components are deployed in the same machine or use TCP binding, when application components are deployed in a separate service (using both ends

We are looking for the right architecture approach for the above scenario.

Please advise.

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
