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

2023-04-27T03:17:39+00:00

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 the cost trade-off you're willing to make. Regardless, if you ever find yourself wanting to use Lambda in a high-activity application like stream processing, it’s good [...]

SFTP On Your Ubuntu EC2 Instance – Quick and Simple Setup

2023-04-27T03:22:05+00:00

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 both run on the same default port (22) for  SSH. However, when it comes to transferring large files securely, SFTP stands out as the better option. [...]

AWS Shared Responsibility Model

2023-04-10T04:05:05+00:00

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 how the customer will manage their resources and ensure the integrity of the system and data. In AWS, security and compliance are shared responsibilities between the [...]

Build Your Own Slack Commands with Lambda Function URL

2023-04-27T03:33:47+00:00

What are Lambda Function URLs? In the past, calling a Lambda function over HTTP required a lot of setup and configuration with API Gateway. The process of setting up API resources and methods, and linking them to the appropriate Lambda function, can be overwhelming, especially for developers who are new to it. With the function URL feature of the AWS Lambda service, you can create a secure HTTPS endpoint dedicated to a Lambda function. This means that instead of using an intermediary service (like Amazon API Gateway), you can directly invoke your function by simply sending an HTTP request to [...]

AWS Cloud Development Kit Cheat Sheet The AWS CDK is an open-source software development framework for defining cloud infrastructure in code and provisioning it through AWS CloudFormation. It provides a high-level object-oriented abstraction on top of AWS CloudFormation that allows you to use pre-built cloud components called constructs. It uses familiar programming languages such as TypeScript, JavaScript, Python, C#, .Net, Java, and Go and deploys everything as CloudFormation stacks.  Concepts: Stacks  a deployment of AWS resources defined in your CDK app. Each stack is a CloudFormation stack and can contain multiple AWS resources.  Constructs:  pre-built cloud components that can be [...]
