Introduction We run some of our services in Docker container, under Elastic Beanstalk (EB). We use circleci for our CI cycle. EB, Docker and Circlec integrate really nice for automatic deployment. It’s fairly easy to set up all the services to work together. In this post, I am summarising the steps to do it. About EB Applications and Versions Elastic ...

Amazon EC2 Container Service (ECS) is Amazon’s solution for running and orchestrating Docker containers. It provides an interface for defining and deploying Docker containers to run on clusters of EC2 instances. The initial setup and configuration of an ECS cluster is not exactly trivial, but once configured it works well and makes running and scaling container-based applications relatively easy. ECS ...

Using HAProxy as a reverse proxy for AWS microservices

devops-logo

Amazon’s EC2 micro instances offer a very affordable option for hosting a Docker-based micro-services architecture. Each micro instance can host several Docker containers.  For example, you may have a simple Node.js-based web application that you would like exposed as subdomain1.myhost.com and another Java/Tomcat webapp surfaced at subdomain2.myhost.com. Each could be hosted through a separate (and perhaps clustered) Docker container, with ...

Long-term log analysis with AWS Redshift

You will aggregate a lot of logs over the lifetime of your product and codebase, so it’s important to be able to search through them. In the rare case of a security issue, not having that capability is incredibly painful. You might be able to use services that allow you to search through the logs of the last two weeks ...

More advanced stuff with JMS and AWS SQS

java-interview-questions-answers
