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 [...]

AWS Global Accelerator vs Amazon CloudFront

2023-04-08T03:37:31+00:00

In this day and age, your site speed performance is an important factor when it comes to user experience. It is widely recommended for websites to have an average load time of 3 seconds as users tend to abandon the site if a page takes longer than 3 seconds to load. According to Amazon, just 100 milliseconds of extra load time cost them 1% in sales. Indeed, every second counts in our fast-paced digital world. Amazon Web Services has always been the global leader in Cloud Computing with its speed, performance, and reliability. With its breadth of services, AWS gives [...]

AWS CodeCommit Repository

2023-06-05T02:10:55+00:00

Amazon Web Services, with its ever-growing breadth of services, offers a fully-managed version control system where developers can privately store their application source code like Github or Bitbucket. CodeCommit can be used as a staging ground coupled with CodeDeploy and CodePipeline to seamlessly deploy code to Amazon EC2 instances.  In this article, I will discuss how we can leverage Amazon SNS to send notifications whenever there are events in our repository. This is particularly useful when we need to keep our work colleagues up-to-date if there are events in our repository. Triggers are used for two things. The first is [...]

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 [...]

2023-06-07T04:11:41+00:00

What is a Customer Master Key (CMK)? In security, a master key is what you use to encrypt all other encryption keys in your system. Customer master keys are logical representations of a master key. They are the primary resources in AWS KMS. The CMK contains the key material used to encrypt and decrypt data. It also contains metadata such as the key ID, creation date, description, and key state. You can start using AWS KMS through the web console or via API. There are two types of CMKs that you can create in AWS KMS: symmetric CMK and asymmetric [...]
