Note To run this application from the local development environment the development storage service and development fabric must be started first. The following screenshots are the test results of Exercise 3-4. 108 CHAPTER 3 WORKING WITH CLOUD QUEUE AND BLOB STORAGE First we upload a large amount of data to blob storage. The results are shown in Figures 3-13 and 3-14. Figure 3-13. File of size 278 MB created and uploaded to blob taking seconds in the local development environment with the system configuration shown in Figure 3-14 Figure 3-14. System conf iguration to run Exercise 3-4 We can also upload a small amount of data to blob storage. 109 CHAPTER 3 WORKING WITH CLOUD QUEUE AND BLOB STORAGE This tool of course can also be used to transmit any size of data between local systems and cloud blob storage. Figure 3-15 shows an example using this tool to upload a small file to a blob storage table. Note that the file name created by the tool in this case has no suffix. Figure 3-15.
