Amazon S3 Event Notifications

2023-02-22T14:35:34+00:00

With Amazon S3 being virtually unlimited in size, it's quite a challenge to keep everything monitored, especially when you are dealing with a large number of objects that scales up from time to time. With Amazon S3 Event Notifications, you’ll be able to immediately know when an object in your bucket was created, removed, or restored. This feature lets you get notifications whenever an event happens on your S3 bucket. These notifications can then be forwarded to an Amazon Simple Notification Service (Amazon SNS) topic, Amazon Simple Queue Service (Amazon SQS) queue, and AWS Lambda function. The S3 Event Notification [...]

Configuring Notifications for Amazon EC2 Auto Scaling Lifecycle Hooks

2023-06-03T05:15:48+00:00

Auto Scaling Lifecycle Hooks In the previous post, we talked about Auto Scaling Lifecycle Hooks and how to configure it on your Auto Scaling group. You can view the article here. It’s better to read it first before proceeding with this section. In a nutshell, Auto Scaling Lifecycle Hooks allow you to put an instance in the “wait” state while the Auto Scaling group responds to a scale-out or scale-in event. While the instance is in the “wait” state, you perform actions such as installing the application before allowing traffic to the instance or sending out the application logs to [...]

Step Scaling vs Simple Scaling Policies vs Target Tracking Policies in Amazon EC2

2023-06-23T05:27:39+00:00

Bookmarks Simple Scaling  Target Tracking Step Scaling  Creating a Step Scaling Policy for an Auto Scaling Group Amazon’s EC2 Auto Scaling provides an effective way to ensure that your infrastructure is able to dynamically respond to changing user demands. For example, to accommodate a sudden traffic increase on your web application, you can set your Auto Scaling group to automatically add more instances. And when traffic is low, have it automatically reduce the number of instances. This is a cost-effective solution since it only provisions EC2 instances when you need them. EC2 Auto [...]

Bookmarks Auto Scaling Lifecycle Hooks Configure Lifecycle Hooks on your Auto Scaling Groups Amazon EC2 Auto Scaling allows you to scale-out or scale-in your EC2 instances automatically based on policies you configured in response to changing demand on your application. Auto Scaling Groups lets you set a minimum and maximum number of EC2 instances to automatically resize your cluster based on a defined schedule or instance metrics such as CPU utilization, network traffic, etc. This is an excellent way to cut costs and make sure you have the correct number of instances since traffic on [...]

Increasing MTU for Your EC2 Instance

2023-06-05T02:27:26+00:00

What is MTU? MTU (maximum transmission unit) is the maximum size of one packet of data that can be transferred in a network. The default MTU size for Ethernet devices is 1500 bytes. This packet size contains the actual payload data as well as network overhead information needed for communication within the network. All AWS EC2 instances support the default MTU size. But many current instance sizes support 9001 MTU, also referred to as jumbo frames. Enabling jumbo frames for supported EC2 instances can be beneficial because it improves network efficiency by allowing your instance to send fewer packets with [...]

Locking your Glacier Vault using the Amazon S3 Glacier API

2023-06-05T03:07:24+00:00

What is Amazon S3 Glacier Vault Lock A Glacier Vault can be described as a container for your archived objects in S3 Glacier. To begin using Amazon S3 Glacier, you need a vault. Creating and deleting vaults can be easily done in the AWS Management Console, but interacting with them requires you to use the APIs. For example, let’s say you want to upload images or log files to your vault. To do so, you would either use the AWS CLI or write code that would upload these objects. Large corporations often have compliance requirements with how they store their [...]

Amazon S3 Bucket Policies for VPC Endpoints

2023-06-05T03:11:03+00:00

Amazon S3 and Amazon VPC Relationship Amazon S3 is a versatile object storage solution that boasts virtually unlimited storage capacity. You can expect that your files will be durably stored in S3 given that AWS provides an SLA for this service. When creating your S3 bucket, AWS provides you with a unique bucket URL that you can use to access your S3 bucket directly from the public internet, if you have public access enabled.  Amazon S3 is a service that is not used within a VPC. This means that traffic does not pass through VPC resources such as internet gateways [...]
