Prevent EC2 Downtime: Setting Up Status Check Alarms to Auto-Reboot an Amazon EC2 Instance
When you’re running a production website on an EC2 instance, the last thing you want is for it to unexpectedly go down while you’re focused on other tasks. Without the right monitoring in place, you might not even realize your site has been offline for a while, and repeated [...]

Don’t Learn AWS Until You Know These Things

Learning AWS is like trying to drink from a firehose. At least, that's how I remember it felt when I jumped into AWS years ago as a non-IT guy. I often bounced around between different articles and Youtube videos, struggling to make sense of all the concepts. One moment, I'd be focusing on an EC2 tutorial but then realize I needed to understand VPCs first, so I'd click over to a video about networking. [...]

Creating And Mounting An Azure File Share

A file server provides organizations with a system to centrally store, manage, and access files within a network, such as documents, images, videos, logs, etc. With file servers, users can easily share and collaborate on files with others. Azure Files is a fully managed file share solution that aims to replace or supplement on-premises file servers. It is a platform as a service (PaaS) offering by Microsoft Azure that is accessible by SMB and [...]

Deploying Docker Images To Azure Container Apps

Containers, cloud-native, and microservices are all used in modern software development and deployment. A container is a standalone executable package that contains everything needed to run a piece of software, creating an isolated environment for the application. While microservices are an architectural paradigm for developing applications composed of small, independent services. This enables teams to autonomously build, deploy, and grow their services, increasing the speed and agility of the development process. In Microsoft Azure, [...]

Reduce The Cost Of Your Lambda Functions With Event Filters (Part 2 of 2)

Introduction In the first part of this post, we covered the concept behind event filtering in AWS Lambda and learned how it could help you save money by invoking functions only when necessary. Now it's time to put that knowledge into practice. In this part 2, we’ll see event filtering in action using Amazon Simple Queue Service (SQS) as the event source. Overview A user sends a JSON message to the SQS queue. Event [...]

Reduce The Cost Of Your Lambda Functions With Event Filters (Part 1 of 2)

Problem statement You are primarily billed based on how long your Lambda functions run and how often it is invoked. This is why AWS Lambda is great for scheduled jobs, short-duration tasks, and event-based processes. But does this mean you shouldn’t use them for high-volume traffic applications? Well, the short answer is... it depends. Whether or not to use AWS Lambda for high-volume traffic workloads ultimately depends on the requirements of your application and [...]

SFTP On Your Ubuntu EC2 Instance – Quick and Simple Setup

SFTP, which stands for Secure File Transfer Protocol, is a method of transferring files between computers. It operates over SSH (Secure Shell) and uses public-key cryptography for authentication. This means that your login credentials and file transfers are encrypted, making them much more secure than the traditional FTP (File Transfer Protocol). Why SFTP over SCP? SFTP and Secure Copy Protocol (SCP) are both network protocols that you can use for transferring files. They also [...]

Automate Resources In Azure Using ARM Templates

Infrastructure as Code (IaC) is a method of running IT infrastructure that automates, configures, and manages systems and networks using scripts or code. It can work with a variety of file formats, including JSON and YAML. YAML (YAML Ain't Markup Language) is a data serialization format that is commonly used in Ansible, Kubernetes, and other tools. While JSON (JavaScript Object Notation) is a popular data interchange format that is frequently used in AWS CloudFormation, [...]

AWS Shared Responsibility Model

Cloud computing is changing the way businesses operate by providing scalable, pay-as-you-go infrastructure and services. The shared pool of configurable computing resources is made up of thousands of powerful physical servers located in data centers around the world and equipped with enterprise-grade processors capable of creating hundreds or even thousands of virtual machines for multiple customers. However, one of the primary concerns when migrating a private infrastructure to a public cloud service provider is [...]

Azure Storage Redundancy Options

What are the Azure Storage Redundancy Options? Azure storage redundancy options provide different levels of protection for data stored in Azure. These options ensure that data is available and retrievable in case of failure or data loss. There are several different types of consistency options available in Azure, each with its own features and benefits. Locally Redundant Storage (LRS) has the lowest level of consistency in Azure storage redundancies. The LRS option stores three [...]
