AWS Global Accelerator vs Amazon CloudFront

2021-05-03T13:33:57+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 [...]

Increasing MTU for Your EC2 Instance

2021-05-03T13:34:43+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 [...]

AWS Transit Gateway

2022-07-18T08:56:07+00:00

Bookmarks Features Validate Your Knowledge A networking service that uses a hub and spoke model to enable customers to connect their on-premises data centers and their Amazon Virtual Private Clouds (VPCs) to a single gateway. With this service, customers only have to create and manage a single connection from the central gateway into each on-premises data center, remote office, or VPC across your network. If a new VPC is created, it is automatically connected to the Transit Gateway and will also be available to every other network that is also connected to the Transit Gateway. [...]

Resolve Route 53 Private Hosted Zones from an On-premises Network

2021-05-03T13:35:09+00:00

Route 53 Private Hosted Zones Amazon Route 53 DNS service supports Public Hosted Zones and Private Hosted Zones. Private Hosted Zones are useful when you want to use your private domain and have Route 53 respond to queries on that domain from resources within your VPC.  For example, if you host a database on an EC2 instance on a private subnet, you can create a Route 53 record set (ex: privatedb.tutorialsdojo.com) for that database instance on your Private Hosted Zone to allow other EC2 instances to resolve the domain name.   But what if you have a VPN connection (or AWS [...]

AWS Global Accelerator

2021-05-03T13:44:09+00:00

A service that uses the AWS Global Network to improve the availability and performance of your applications to your local and global users.  It provides static IP addresses that act as a fixed entry point to your application endpoints in a single or multiple AWS Regions, such as your Application Load Balancers, Network Load Balancers or Amazon EC2 instances. AWS Global Accelerator continually monitors the health of your application endpoints and will detect an unhealthy endpoint and redirect traffic to healthy endpoints in less than 1 minute. How It Works Concepts An accelerator is the resource you create to direct [...]

Longest Prefix Match: Understanding Advanced Concepts in VPC Peering

2021-05-03T13:34:47+00:00

VPC Peering Basics In AWS, a Virtual Private Cloud (VPC) peering connection is a networking connection between two VPCs which allows you to route specific traffic between them using either private IPv4 addresses or IPv6 addresses. A VPC peering connection can be created between your own VPCs, or alternatively, a VPC in another AWS account. You can also create an inter-region VPC peering connection where the VPCs are located in different AWS Regions. Amazon EC2 Instances in either VPC can communicate with each other freely as if they are within the same network. One example of VPC Peering is the [...]

How to invalidate API Gateway Cache

2021-05-03T13:34:08+00:00

To invalidate an existing cache entry of a request and retrieve the latest data from the integration endpoint, one must send the request together with the Cache-Control: max-age=0 header. If the recipient is authorized to communicate directly to the integration endpoint, then the integration endpoint will respond with the latest data for the request. This also replaces the existing cache entry with the new response. The IAM Policy that grants a client to invalidate the cache follows: {   "Version": "2012-10-17",   "Statement": [     {       "Effect": "Allow",       "Action": [         "execute-api:InvalidateCache"       ],       "Resource": [ "arn:aws:execute-api:region:account-id:api-id/stage-name/GET/resource-path-specifier"       ]     }   ] }    An alternative option [...]

VPC Peering

2021-05-03T13:34:45+00:00

A networking connection between two VPCs that enables you to route traffic between them privately using private IPv4 addresses or IPv6 addresses. Instances in either VPC can communicate with each other as if they are within the same network. You can create a VPC peering connection between your own VPCs, with a VPC in another AWS account, or with a VPC in a different AWS Region (also called Inter-Region VPC Peering). A VPC peering connection is neither a gateway nor a AWS Site-to-Site VPN connection, and does not rely on a separate piece of physical hardware. There is no single [...]
