Simple Notification Service (SNS)

Unlike SQS, SNS shines in broadcasting messages. Imagine a town crier: SNS publishes messages to "topics" (town squares), and any subscribed "subscribers" (residents) receive copies (hear the message). Perfect for mass notifications like emails, SMS, or app pushes. While delivery isn't 100% guaranteed (unlike SQS), it's ideal for event-driven messaging, spreading the news when something happens.

Cloud services offer a vast menu of tools, like messaging platforms. These platforms enable apps to chat asynchronously, ensuring messages get delivered even if the recipient is offline. This frees developers to focus on core logic, leaving the communication infrastructure to the service. Popular examples include SQS and SNS by AWS, and Service Bus by Azure. SQS, a messaging queue, buffers messages and delivers them in the order they were sent, prioritizing reliability with features like retries and dedicated queues for undeliverable messages. If you need ordered or guaranteed delivery, SQS is a strong choice.

Creating and tearing down a Virtual Private Server on Amazon LightSail involves not only the server but also its related resources like public IP, DNS zones, containers, storages, and databases to avoid additional charges. Users should methodically delete instances, containers, databases, static IP, and DNS zones to prevent unexpected costs and clean up the environment.

This tutorial explains monitoring cloud infrastructure using eG Innovations' SaaS, detailing steps from signing up for a trial to monitoring AWS cloud instances. The process, utilizing a remote agent, covers discovering cloud resources, installing agents for converged monitoring (Metrics, Events, Logs, Traces), and receiving alerts for anomalies. Observability without writing scripts through Metrics-Events-Logs-Traces (MELT) is emphasized, with the promise to later discuss different monitoring methods.

5 Steps to Monitor Lightsail VM using Amazon Cloud Watch

February 5, 2024Posted inCloud Computing, Observability
Amazon Cloud Watch and Azure Monitor are native cloud monitoring tools that can be bundled with cloud subscriptions, sparking debate over their sufficiency for full observability and SRE MELT goals. The post details a five-step process for monitoring AWS Lightsail VMs using Amazon Cloud Watch, covering installation and configuration of the AWS CLI and CloudWatch agent. This process is vital as Lightsail VMs do not natively include AWS CloudWatch agents. Additional metrics, such as memory and network consumption, can also be monitored, though troubleshooting may be necessary for some metrics to appear.
