If you deploy any type of application on AWS, such as a Ruby on Rails web app; then your application will generate large amounts of logs. Hence, you will need to store and monitor these logs somewhere to understand what is going on when an unexpected event occurs. A central log server may be a choice; however, Amazon CloudWatch offers an alternative way without maintaining your log servers and with lots of capabilities.

In today’s blog post, I will describe how you can start storing your application logs on Amazon CloudWatch by using a Ruby on Rails web application as an example. The same principles here would apply to other types of application logs as well.

When you launch an Amazon EC2 instance, you define an Amazon EBS volume size. However, you may eventually need more disk space later for some reason. In this blog post, I will demonstrate an example of how you can increase the root volume size of an EC2 Linux instance.

Angular and Bootstrap are very useful tools when developing front ends. You can build single page applications with powerful features of Angular and make them look pretty by using Bootstrap classes and components. They both have new versions now, coincidentally each has version 4. However, Bootstrap 4 is currently in beta stage.

In this blog post I will explain how to import Bootstrap 4 Sass module in an Angular 4 application as SCSS.

While managing your resources on AWS, you may need accessing services programmatically. You may need to get information about an instance or modify some attribute. In some cases, you may need a cron job that runs every hours or once a day. For example, it can be a job getting the name of the current master node in an ElastiCache Redis cluster.

Writing Python scripts is an easy way to access and use your AWS resources. Besides, you can use Python for coding your AWS Lambda functions. In this blog post, I will give a simple example to listing VPC components using a Python script.

In our Ruby on Rails web applications, we use Amazon S3 to store files. Uploading files to Amazon S3 buckets via HTTP requests requires signing the request. The current recommended, and safe signing method is Signature Version 4, and AWS regions opened after January 30, 2014, such as London and Frankfurt, only support this version.

In this blog post, I will try to explain how to sign HTTP requests for Amazon S3 uploads in a Rails application and make requests by using AngularJS ng-file-upload module.
