Measuring performance of User Interface and REST service layer separately

Recently we were working on a project where we were looking to separately measure performance of UI (User interface) and REST service layer separately.

Technology involved were- C#.Net 4.5, MVC5.0, JQuery, JSON, XML, Restful Services

So we were searching for a profiling tool which can server our purpose with minimum cost and time/effort involved.

We found several tools that can be used -

• dotTrace
• Mini-Profiler
• MaintainJ
• Dynatrace 

Hope this helps someone who is looking for similar profiling tool.

Few points about Micro-services architecture

Micro-services are not meant to be scaled down version of SOA (Service oriented architecture). They should be based on business context and should not be created based on technical refactoring viewpoint.

Ideal platforms for microservices would be cloud were you can easily scale any one component we want. Example if we notice that one business component (say UI) need support 1000 instances and rest every thing can be 1 or 2 instances then decompose the UI component into a microservice

Cloud platforms and dockers are good area to experiment with micro-services as scaling, and management of  multiple versions can be easily accomplished there.

Few no's for microservices -

• No clustering should be planned
• Try to make integrations independent of programming language (rest, http, xml)
• Avoid single database for multiple microservices

Finally one word of caution, managing multiple microservices is very important. Otherwise after 5 to 6 microservices people loose track of which version is integrated to what.

jQuery data-table with features similar to excel

Recently in one of our projects, we were looking for a jQuery data-table with basic features similar to excel viz. -

• Navigate from cell to cell in a row using right arrow/tab 
• Enable cell edit key press after selecting the cell 
• Enable auto suggest based on the existing data in the column 
• Enable copy of cell and paste to another cell 
• Enable drop-down  to chose values rather than free text 
• Enable column freeze 
• Enable column wise filters

While researching for it, we found few useful components that provides these functionalities. 

1. Slickgrid jQuery plugin
2. Handson table
3. JQGrid

Hope this will help in any teams looking for data-tables with similar functionality.
