Push Spring Boot app metrics into AWS CloudWatch
Spring Boot is one of our favorite topics on this site. We believe that no matter how much we post about this theme, we still not be able to exhaust the subjects. Recently we found a very interesting library that it deserves to be tried. But before starting discussion about it, let’s say two words […]
Plugin for drawing AWS Step Functions Workflows
Even if we try to be unbiased in our articles, we know that, based on topics we present, you can guess what services we are using, what tools are useful for us and so on. If we speak about orchestrating services, one of our favorite choices is AWS Step Functions. It’s definitely easier to use […]
A better AWS command line interface
We don’t know about you, but as we had mentioned many times, we do love to interact with AWS using command line interface. Yes, we are developers, yes we use the SDK – especially the Java SDK, but there are cases when the CLI gives us more flexibility and helps us making things faster.Recently, we […]
Controlled chaos for testing your microservice
If you run a distributed application you know that even you have 100% code coverage, integration and acceptance tests, there are components you cannot control. You cannot control hardware failure, you cannot control network latency, DNS failure and so on. Today’s post is about a library that can help testing your Spring Boot application with […]
A helping tool to choose EC2 instance type
Whenever we have to make a choice, it’s difficult. But when you have hundreds of available options, the mission is even harder. It’s the same situation when you have to choose hardware type for a service: there are many EC2 host families, generations, number of cores, amount of RAM and so on. Moreover, some instances […]
An interesting library to extract metrics for AWS calls
Probably you know that we published a library that can be used to fetch some basic stats about AWS calls. That library uses an AWS request handler to build metrics that are later published in a text file, in various formats. Recently we found an interesting library that does almost the same things, in a […]
Integrating localstack in your Sprint Boot application
A while ago we presented localstack: a framework that mocks many AWS services allowing you to develop cloud application even when you don’t have Internet connection and without spending any cent. Starting from that, we discovered recently a pretty nice library that can be used to integrate a Spring Boot application with localstack. In that […]
Multiple SSH sessions on EC2 instances in a single place
Recently we changed the audit log format and the old schema became incompatible. The solution acceptable for us was to truncate existing log files instead of making an entire transition with an intermediary step, a cleanup step and so on. Well, this approach seems to be a simple one, but the question is: how to […]
Tool to analyze AWS costs interactively
Recently we discovered a solution that could help you monitor and analyze AWS costs in a very nice manner, providing more details than the default AWS billing console. The tool is named Total Cloud (https://totalcloud.io). First of all, it takes only 2 minutes to sign up. After that you have to create a read-only AWS […]
