Introduction When two services, let’s call them Frontend Service and Backend Service, are communicating with each other, the most straightforward way is for one to call the API endpoints of Backend Service. This synchronous call is usually accomplished by making that RESTful call to the service or by using a client package that the receiver…

Previously I talked about how any system can talk to any other system using an API, in Poller’s case, using WebApi. Each area of functionality can be accessed through a controller, e.g. Client Controller, Agency Controller, Polling Controller, etc. Each controller is only the entrypoint for that area, they only receive the request, direct where…

I was originally going to start writing about Data Access, and how it should be abstracted and encapsulated so if the database changes, it’s easier to replace the code that accesses it. However, after doing some research, I read about the term “Persistence”. By using Persistence we are expanding the reach of the application, it…

New Year, New Name (Hopefully New Client)! When I came up with the name for this project I was very proud, I wish I had done more research before I started to code. You know what they say hindsight is 20/20. Oh well, I should’ve failed earlier. I had to go back to the drawing…

At my day job, I have been working with HashiCorp’s Terraform. Terraform is a way to achieve “Config-as-code” or “Infrastructure-as-code,” and I Love it! Setup As a company grows, it acquires more people, more infrastructure, and new third-party tools, and moves more things to the cloud. Managing changes from many developers to infrastructure or third-party…

Before even starting this project I knew I had to use some kind of project management system. I was deciding between two options: Trello and Basecamp. Trello is a simple-to-use online board: A card, which represents a body of work, is organized in a set of lists or columns. Each column is a state in…

When I originally migrated Poller to a Virtual Machine on the cloud, the process was simple and straightforward: Install the services manually, install a database, open the ports so that clients would be able to access the information, and set up a URL that will redirect to that VM. Everything was set for the demo.…

Before I start talking about the back-end, I want to mention the pattern in which web projects are built: any modern web application has different layers, and each layer should only do what it’s supposed to. Mainly it goes Frontend, Backend, and Data Layer (could be a file, database, another API, or any other mechanism…
