As enterprises move to the Cloud, having a reliable network connection to their on-premises data centers is fundamental. In this post, I show how to monitor your AWS Direct Connect links and initiate remediation (including automatic failover) when degradation in end-to-end path quality (packet loss, high latency) is detected. Multiple Direct Connect links at separate […]

Introduction There are several factors that contribute towards your overall costs incurred in AWS cloud. When it comes to networking, many customers ask about data transfer charges. You pay a Data Transfer charge when you send data out from AWS to Internet, between AWS Regions, or between Availability Zones (AZ). Today, there are multiple ways […]

In this post, you will learn how to deliver compressed WebGL websites to your end users. When requested webpage objects are compressed, the transfer size is reduced, leading to faster downloads, lower cloud storage fees, and lower data transfer fees. Improved load times also directly influence the viewer experience and retention, which will help you […]

Introduction You may run into occasions where, due to sanctions from governmental organizations like OFAC (Office of Foreign Assets Control), you need to implement granular city-level embargos for your websites.

Update: On September 27th, 2021, we launched Application Load Balancer(ALB)-type target groups for Network Load Balancer (NLB). With this launch, you can register ALB as a target of NLB to forward traffic from NLB to ALB without needing to actively manage ALB IP address changes through Lambda. You can also use AWS Global Accelerator to […]

AWS Transit Gateway simplifies your network and puts an end to complex peering relationships. It acts as a cloud router and scales elastically based on the volume of network traffic. It can centralize connections (known as attachments) from your on-premises networks, and attach to Amazon Virtual Private Clouds (VPC) Virtual Private Networks (VPN), AWS Direct […]

If your network architecture is complex, and you’d like to quickly identify application connectivity issues due to infrastructure changes, then the new Amazon Virtual Private Cloud (VPC) Reachability Analyzer can help.
