Spring Boot is a framework powered by Java. As such, it allows you to use Java code to connect with and interact with a database. Because Java is all about OOP (Object Oriented Programing) the name of the game is to write Java Classes that can be mapped to tables in a relational (SQL) database. The classes are not what technically are mapped, but rather, the objects that the classes generate or instantiate.
In technical terms, We’re talking about an ORM (Object Relational Mapper). This is provided by a Spring Project known as Spring Data JPA.
For the past several months, I have been doing a lot of research and investigation into coding bootcamps. Why exactly have I decided to enroll in a coding bootcamp in the first place? Isn’t this blog and website about my passion to become an expert in Amazon Web Services? Why am I now talking about coding bootcamps?
Well, I found that there was a major gap in my learning of AWS. As I strove to figure out how to build solutions in AWS, I found that nearly all the solutions pretty much require some degree of coding and software development…
An important AWS exam topic is to know what Cloudwatch can monitor by default. If you go to the cloudwatch metrics, you can see some of the default metrics, as seen below:
I registered for the Certified Solutions Architect Associate Exam August 12th, 2018. This is the official final day you can take the older version of the exam. The new version was released in February, 2018 and the word on the street is, it’s harder than the older version. The newer version contains more longer scenario based questions, incorporating more of the “Well Architected Framework“.
So what have I been doing to prepare for the exam? Well the past year and a half or so, I’ve been attending classes, learning, and practicing AWS. Interest is the primary driver to learn. Since…
EC2 Instances primarily utilize storage known as EBS Volumes. But this isn’t the only type of storage that is available. There’s another type, known as Instance Store, or Ephemeral Storage.
Instance Store was first used by Amazon, until they shifted to Elastic Block Store. There are several differences between EBS and Ephemeral Storage that may be worth understanding for us as Cloud Engineers.
[table id=1 /]
The AWS Documentation mentions that Amazon Instance Store is designed for temporary storage for EC2. Things like Buffer, Cache,, in Raid Arrays, or Temporary Backups. are some possible use cases for instance store.

I’m currently going through a course on Amazon Web Services, taught by ACloud.Guru. His course is specifically focused on preparing students to pass all of the AWS certification exams. The course consists of important theoretical concepts as well as hands on labs.
We have a lab today regarding Upgrading our EBS Volumes. The scenario is as follows:
You have a server running a 22 GB magnetic hard disk drive (HDD). You have been requested to upgrade the hard drive of the server to a high speed SSD drive. …
I remember back to my 1980 Macintosh Plus. I always looked forward to getting new floppy disks from my Uncle. One day though, he sent me this large heavy device. He told me to connect it to my computer and then I could start up my mac without any of those floppy disks. I was confused. How can I start a computer without putting in the floppy disks? I wondered.
This was my first experience with a hard drive. Shift forward 30 years later, and now our heads are in the clouds. But even in the Cloud, we still will…

As I’m learning AWS, I’m trying to do everything I can in the AWS ecosystem. It gives me a chance learn more about AWS, and get hands on exposure to the platform. My first AWS project was to host this blog entirely in AWS. I’ll go into details in another post, but briefly, I set up an EC2 instance with a WordPress AMI, then I set up the domain using Amazon Route 53.
WIth most other web hosting providers, like (Hostgator, iPage, Bluehost, 1&1 , etc.) …
