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

2023-04-27T03:15:40+00:00

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 source mapping picks up the message from the queue and evaluates it against the specified filtering criteria. Event source mapping invokes the Lambda function synchronously when [...]

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 [...]

Cloud Computing Service Types: IaaS vs PaaS vs SaaS

2023-04-12T02:11:44+00:00

What is IaaS, PaaS, and SaaS? IaaS, PaaS, and SaaS are three types of cloud computing services provided by Microsoft Azure. Each model has its advantages that help customers meet their specific needs. Each type of cloud computing service, and deployment method, provides you with different levels of control, flexibility, and management. With traditional on-premises data centers, customers have complete control over the hardware, server, virtualization, and software deployed. Historically, this has led to hardware procurement decisions focusing on scaling up. An example is purchasing a server with more cores to meet peak performance needs. Unfortunately, this infrastructure might be [...]

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 [...]

2023-04-27T03:39:09+00:00

What is AWS CLI? AWS Command Line Interface (CLI) is a tool used to manage and interact with AWS Services using the command line. Users more comfortable in the command line can leverage the AWS CLI as it offers the exact scope of functionality as the AWS Console.  AWS CLI requires minimal configuration before you can use it. Installed it on your local machine running on Linux, Windows, and macOS.   What is the Difference Between AWS CLI and AWS CloudShell? Likewise, AWS CloudShell is another tool you can use to manage AWS resources using the command line interface. But [...]

AWS Cloud Development Kit (CDK)

2023-06-22T14:02:45+00:00

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 [...]
