Problems in the creation of a cloud deployment option

[Anonymous]

Hi,

I've been using CloudMIG Xpress for a few days, but I didn't succeed in the creation of a cloud deployment option (section 3.7 from CloudMIG's user guide). When I try the option “Automatic Creation – Standard” apparently works fine, but the next step in the general process remains inacessible. The option “Automatic Creation – Optimized” take several hours without significant progress. There is something that I can do in this case? There are specific parameters for the option “Automatic Creation – Optimized” that produces results in less time?

P.S.: I'm using the JPetStore for testing the software and my computer already have a proper instalation of Java 6 32 bits.

Hi,

thanks for your interest in CloudMIG Xpress. The CDOs produced by “Automatic Creation – Standard” are, unfortunately, not available via the GUI for usage in the further general process. It has to be said that the development of CloudMIG Xpress stopped.

The focus was on the “Automatic Creation – Optimized” option. This option includes lots of simulations and produces valid results, but only after several hours to days (depending on the machine you are using). The produced CDOs are also not presented at the GUI, but only logged in a text file (this was sufficient at the time CloudMIG Xpress was written).

Regards

The step after the CDO generation is important for a research that I'm doing, so just to confirm: Will I be able to proceed in the general process after the "Automatic Creation - Optimized" option finish the execution?

Thanks for the help.

No. After the "Automatic Creation - Optimized" option finishes, CloudMIG Xpress 0.5 Beta solely writes a text file to disc that includes an approximation of the pareto optimal front of CDOs.

Hello.

Thanks for your time writing the documentation and answering questions.

I tried to run the Automatic Creation – Optimized option and it takes several days as you said.
My question is can I get an idea of the final output to see if is something I can use? And if this procedure ever finishes on my pc where would the log files be created?

Hi,

the resulting text file includes an approximation of the pareto optimal front of CDOs in CSV format. It will look like the following example content:

Cost;ResponseTime;NrTimeouts
23.349999999997;2162.7985816885484;455.0
0.5000000000000001;1930.0;192.0
47.93000000000002;1608.3807448994776;2357.0
...

The resulting file can be found in a user's or system's temporary directory. Depending on your OS, this may, for example, be

"C:\Users\Username\AppData\Local\Temp" in the case of Windows 7, or
"/tmp/" for Debian-based Linux systems

The results of an optimization run are stored in a directory "GARun_DATE_TIME", where DATE and TIME are set to the date and time the optimization run was started. Therefore, if you cannot find the
location where the results are stored, you can search for the directory by wildcard "GARun_*".

I hope this helps.
