Introduction # Today we are going to do a hands-on on how to kill a dangling EIP or in other words, deallocate an unassigned Elastic IP. But before that, let us know…
What is an Elastic IP and why do we need it? # Elastic IPs are simply IP addresses provided by Amazon AWS. These are usually attached to internet gateways such as load balancers, or even EC2 instances. I have been using it with EC2 instances directly for my testing use case.
Introduction # This is second and final post in the series of creating a S3 thumbnail system with Lambda.
You must already be aware of the prerequisites from the last section. To follow this post, familarity with Python would benifit.
This is second part of the 2 section tutorial:
Test the Trigger Make the Thumbnail (you are here) We are doing Make the Thumbnail.
Introduction # In this post, we are going to see how we can use existing AWS infrastructure to create thumbnail for uploaded images. In this venture, we are going to use S3 trigger to execure Lambda function to do whatever we want. But in this case, we’ll create thumbnail so that we can save on some bandwidth when only a smaller version of image is required on the frontend.
Introduction # Started with my Pentium 4 processor desktop with merely 256 MB of RAM. And today I’m port forwarding sitting on my laptop in a cloud enabled web. Today we’ll see how I have manage to make a tunnel between my laptop and EC2 instance that I own.
In this short post, I will show how we can forward port from a remote host to a local computer. We will forward a port from AWS EC2 to local computer with openssl.
Introduction # I have been using AWS with Terraform to provision my development instance on AWS cloud. When I wanted to configure dotfiles, change SSH port and configure some cron jobs, I hit a bottleneck. I literally was not able to do those tasks with user scripts because they had no effect. That was the time when creating custom image of the distro came into my mind.
This is my rundown of AWS’s whitepaper about Implementing Microservices on AWS. Without further ado, let’s get started. In this article I talk more about micrsoservices and less about AWS. I also talk about paths already engraved around microservices.
While you read this post, take a moment to connect with me on LinkedIn.
What are microservices? # Microservices are an architectural and organizational approach to software development where software is composed of small independent services that communicate over well-defined APIs. These services are owned by small, self-contained teams.
In a previous post we discovered how can we run commands on each push and check if the test is passing against multiple versions of go. This is a continuation of the same concept. We are going to deploy our code to Elastic Beanstalk, straight from git push.
Elastic Beanstalk is nothing but a wrapper around it’s EC2 infrastructure. It is a developer-centric view of deploying an application on AWS. Developers just have to push the code and Beanstalk can take care of Auto Scaling Group, Elastic Load Balancer, databases etc. No need to manage infrastructure manually.
You can’t think of deploying your application to production without testing it.
Neither you can manage a large codebase with confidence without it.
Let us go through some basics of unit testing in golang.
This post is structured in the following manner:
unit testing basics in golang (jump) inbuilt code coverage command understanding subtests and helper function (jump) Travis CI integration (jump) running test against multiple version of go Please connect with me on LinkedIn and let’s get started.
