When beginning with AWS, the concepts of Regions, Availability Zones (AZs), Data Centers and Edge Locations can be a little confusing. Let's review some facts that will help clarify what these things are and the relationship among them. For the moment, let's remove Edge Locations from consideration. The intent of an Edge Location differs slightly [...]
Write the file in the current directory with the same name. curl -O http://download.aircrack-ng.org/aircrack-ng-1.2-rc4.tar.gz Note that the -O is the letter "oh", uppercase. According to man, -O: Write output to a file named as the remote file. Featured Photo by Daniel von Appen on Unsplash
As one begins to write more sophisticated AWS Lambda functions, it quickly becomes clear that using shell scripts and the CLI to package, deploy and test will speed up development time. I often start in the AWS Console; then as the code becomes more complex, move to a local editor. Packaging at the Command Line [...]
Note: this is a conceptual, "how does the SWF design pattern work" article, rather than a "how-to". In fact, implementation does not need to be Amazon specific, although SWF supports the pattern. A Naive, Simple Code Example We may write fairly complex algorithms to fulfill the needs of a complex process. One could write a single function [...]
Given a fileserver change, I needed a way to get all the server names for Receive Locations in the BizTalkMgmtDb. The InboundTransportURL would be in the form of \\servername\somepath. This query assumes a valid charindex value -- often a dangerous assumption. This did the trick nicely! select [id], [name], [ActiveStartDT], [InboundTransportURL], replace(left([InboundTransportURL], charindex('\', [InboundTransportURL], 3)), '\', [...]
As with most things involving AWS and the CLI, deleting Log Groups is quite straightforward once you know the syntax. Given a log group called "HelloAgain", use the following: aws logs delete-log-group --log-group-name /aws/lambda/HelloAgain That's it! To easily get a list of logs: aws logs describe-log-groups | grep "logGroupName"
While working on a project, I was looking for a concise introduction to integrating VisualStudio.com with Visual Studio itself. What follows is a step-by-step for what I wish I would have found. My goal was simply to get my project under source control. This isn't the only way, but it is a way. We'll assume [...]
Postman is pretty handy for viewing the return values of POSTs, but also for debugging during the early phases of development. In my case, I was trying to POST to my Alexa app. developer.amazon.com was reporting a 500 error, but nothing beyond that. This was in the early stages where I had not yet created [...]
I was looking for a simple way to deploy files from a machine running Visual Studio to an EC2 instance hosting IIS. My goal was to code-deploy-test / code-deploy-test into AWS. Simple was good. Several options presented themselves including SFTP and CodeDeploy, but I happened across an option that really suited my needs for the [...]
In the AWS Console, log into Route 53 and navigate to Hosted zones. Section I: Create a Record Set for the EC2 Instance Click on the Create Record Set button at the top of the page. In the Name field, add "www". In the Value field, add the IP address of your EC2 instance. (Note [...]
